People who are interested in gardening equipment often want to find out how to make a plow for a motoblock with their own hands. With the help of such a design, various works related to agriculture can be performed. Such work can be attributed to: pc, sowing, plowing, planting vegetables, etc. However, a corresponding agricultural device is needed for each of the types of work. Therefore, almost every dacket wishes to make a homemade plow for a motoblock.

The construction of a plow for a motoblock with their own hands, whose drawings are shown in Fig. 1 is not a complex process.

Plows are different speciesEach of which is a special device. For example, for plowing, in most cases, a single-door, rotary or revolving plow is used.

The easiest way to make a one-circuit plow. It has a simple design and consists of only several elements. This option is most suitable for subsidiaries, which have no appropriate work experience.

Making a plow is very simple. For this, special devices or tools will not need. You can use the items that are stored in the garage room.

Motoblock Plow Construction Process

Figure 1. Plow drawing for a motoblock.

Lemeh Plow must be removable. The cutting element of the design is recommended to be made from doped steel, which is used in the production of circular saws.

Stal 45 is suitable, which can be tested to hardness 50-53 by hardening. If there is only ordinary steel, which does not work out to be treated with a thermal method, it can also be used to cut the soil reservoir. To do this, you need to repel the edge for cutting cold lemhery on the anvil, then sharpen it.

Elements that will be needed:

• steel tube;
• dense cardboard;
• welding device;
• sandpaper;
• a hammer;
• steel sheet with dimensions 50x50 cm.

How to construct yourself?

There are several methods for making a dump for a plow. The working basis of the dump should be given a cylindrical shape. If there are rollers for flexible sheets, then give the details the necessary form is very simple.

Figure 2. Drawing of a plow dump.

The drawing of the dust of the plow can be seen in Fig. 2.

To obtain the desired result, you will need a piece of dump, which is cut with a 2-3 mm thick welding of the sheet, cut on the rollers at an angle of 22-24 °. Next, the element must be taken, after which the hammer to give the necessary form. You can do this by using a template.

There is another manufacturing method. The detail for the dump can be made from the steel tube with a diameter of 55-60 cm. The thickness of the walls of the workpiece must be 3-4 mm. First of all, from dense cardboard, you need to make a dump pattern. After that, the part should be applied to the tube so that the lower part of the duck pattern was with an angle of 21-22 ° forming the tube in the form of a cylinder.

The shape of the dust from the tube with a diameter of 55-60 cm is shown in Fig. 3.

Figure 3. Shape of dust from the tube.

The loop circuit should be drawn with chalk, then cut out welding and handle sandpaper. If required, the shape of the dump can be adjusted by the hammer on the manufactured pattern.

The most time-consuming method of the construction of the dump is to install the part in the mountain for heating. Next, the item will need to exit by the matrix, which can be taken away from the finished design.

A sheet of steel can be used as a material for the plow hull.

The drawing of the plow elements can be seen in Fig. four.

First of all, it is recommended to produce plow elements from paper, after which it is recommended to clean them with an adhesive mixture. Indicators of one corner on different parts The housings can be from 25 ° to 120 °, of the other - from 40 ° to 50 °. If the design of the paper suits all criteria, then you can start making a metal device.

Figure 4. Drawing of plow elements.

When parts of the steel plow are made, an additional sheet 50x50 cm will be needed to build a case. It will still be necessary to prepare a welding machine. On a sheet with an indentation from extreme parts, you will need to postpone the angle Γ.

With the use of blades on the sheet, you will need to install the lemhech and welcome the item on both sides.

With Lemeh, you will need to dock the side panel of the rack vertically so that its extreme part goes to the extreme parts of the lemum for 6-7 mm. The side shield should be raised above the lemis blades by 6-8 mm. In this case, Lemeh will be able to cut the earth without free. The shield should be welcomed to the lemmone and sheet.

Figure 5. Fastening of the lemum.

If it turns out that the bases or angles will not match, then the damage should be finalized by the hammer. After the dump fit is performed, the detail in the back should be grabbed with the welding to the lemule and the shield in the side zone of the structure. Next, the side element will need to be welded with a rake for spacers and a plate. In the next step, using welding, you should grab the corners for the stop.

Next, the plow should be inspecting, after which it is overhamed to cook. An additional sheet that is used to assemble the plow must be separated from the case a chisel or saw with a disk for cutting. Corners for stop should be welded to the base plate. Next, welding seams need to be cleaned, and the base of the dump and the lemhech is treated with a grinding tool.

How to make a swivel plow self?

The swivel tool is a universal design that assumes the presence of a manual mechanism on an ordinary coupling. In the process of soil plowing, the soil reservoir can be turned over with a lemene one way. In order for the land of another row to turn over in the same direction, it will take back to the beginning of the first row and start from this site.

With the help of such a plow, the plow can be made much faster - after the design of the structure at the end of the row, the lemeh can be deployed in the opposite direction. Next, you can continue to handle the soil.

The rotary product can be characterized by the presence of several structural planes. If, after dismantling the lemum and dust, the plow mount on the horizontal table, which is close to the wall, then press its side base to the vertical wall, the base of the table coincides with the lower horizontal base of the car. The vertical wall at the same time coincides with the side base of the car.

Nuances that should be considered:

1. The first condition for high-quality design is the placement of the lower cutting part of the mounted lemum 15-20 mm below the horizontal base of the car.
2. Another condition of a reliable design is the docking of the front base of the lemum with a blade in a single plane and without cracks. In this case, there should be no protruding parts for fasteners. All items must be polished.

When all work with a plow will be completed, the polished bases will be cleaned from the soil, pour with machine oil, after which it is lost with a rag. Such actions will protect polished bases from corrosion.

The back side of the lemch must be smooth, with a flat base of the plow, it should be an angle of 18-20 °. The side edges for cutting must have rear corners of 12-20 °.

How to mount a plow on the motor-block?

Before performing the Plow setting, you will need to prepare a motoblock and mount a plow on it. To do this, the device should be positioned on the working base. Wheels with tires made of rubber will be removed, after which you can mount the gripped wheels from the steel. This is necessary in order to reduce the bushing of the motoblock in the process of plowing due to the resistance of the soil.

When the plow on the motoblock is installed, you can begin to fix the attachment of the plow for the motoblock. Fixation nuts will need to be tightened not to the end so that the unit can be adjusted. Next, you will need to attach the device to the fixing ring by several steel pins. After that, the manufactured design is adjusted.

Plow adjustment for the motoblock is made taking into account all existing rules, since the quality of plowing will depend on this process. First of all, the motoblock wheels need to be installed on the stand, after which it is balancing.

After the plow is fixed, it will take a motoblock with a stand and install on the ground. The steering wheel is exhibited so that the handles are located at the height of the user's belt.

You can find a rotary type plow. The design provides for the presence of existed lemhehov, which are mounted on the axis. A rotary device can handle the ground to a depth of about 26-30 cm, while the cost of the user's forces will be minimal. However, it is very difficult to build a similar device.

Conclusion

Make a plow simply. To do everything correctly, you need to follow the sequence of actions.

At the end, it will be necessary to evaluate the correctness of the design settings. To do this, check the control plow, then measure the cutting depth. In the end, you will need to measure the distance between the grooves. If the distance between them is more than 10 cm, then you will need to re-adjust.

Figure 1 - Single-door mounted homemade plow.

Before starting work on creating a self-made plow for a motoblock, you need to carefully approach all the available documentation. Check out the process first in theory, then you can go to practice.

We warn that the tools should be professional, then they will help to perform all work manually and at a high level.

Amateur tool is not suitable for creating a plow for the reason that it has low strength.

If there are no skills in such matters, first, first talk with specialists who will tell how to make a plow for a motoblock with their own hands and describe the main pitfalls that begin the beginner constructors.

Plow design

Plows are divided into several species, each of which has features of the shape and design.

• one-poultry;
• rotary;
• turns.

Figure 2 - an example, as a self-made plow for a motoblock looks like.

A single-door plow for a motoblock is the simplest in its design, drawings for this type of products are a lot. It is suitable for beginners of Kuznetsov, because to make it simple.

The homemade revolving plow for the motoblock is interesting because the top of the case is a curved pen, so that the gardener has the opportunity to immediately turn the earth during processing. This product is perfect for solid land. Such an aggregate will be able to sow only professionals.

The most complex design is a rotary plow. It is most like a cultivator due to the presence of several lempets that are attached on one axis. When processing the soil, the axis turns, and due to this, the whole reservoir of the soil is coated.

How to make a plow do it yourself

We must take into account that without drawing you can do a plow. Drawings of a self-made plow for a motoblock See at the end of the article in the photo section. You need to accurately comply with all instructions and read the parameters carefully. After all, the slightest blot can significantly affect the character of the plow. Let's start with a single-dulled motorcoall that makes it yourself.

Figure 3 - drawing of a single-duty homemade plow.

Lemeh

Figure 4 - Drawing of a single-populated plow.

For the creation of working elements, the plow is perfectly suitable with a thickness of 3-5 millimeters. First, it is recommended to work on a removable lemmet, best Material For it, this is a disc from the circular saw (alloyed steel 9xc).

For lack, it is possible to use an ordinary, not subject to thermal processing Steel, for the cut of the layer of the Earth. The cutting part of the lemis should fight back on the anvil, and then hide, like the working part of the braid.

Dump

When Lemeh is ready, you can begin to make it dump. Here, a pipe with a diameter of 0.5 meters is perfectly suitable as a material, the wall thickness should not exceed 5 millimeters. The billet of the dump is cut with a gas cutter, on the finished template (template, make from dense cardboard). And then it is communicated to the condition on the anvil, and then on the grinding machine.

Figure 5 - Drawing of a plow dump for a motor-block.

Plow assembly

Figure 6 - Plow assembly with lemhery angle.

To collect the details of the plow to the motoblock into a single design, we recommend that you perform this operation first on the layout. From thick cardboard, cut the appropriate parts and glue with each other, sticking to the necessary angle:

• angle of alpha 25 ° - 130 ° in different parts of the case;
• the angle of gamma 42 ° - 50 °.

If the cardboard layout is constructed correctly and withstand all the parameters, you can start working with a plow.

After the decoration of the lemis, the dump and auxiliary parts for fastening, a steel sheet will be required (thickness 2-3 mm, an area of \u200b\u200b500x500 mm). We make an indent on the edges of 40 mm, align that the angle of gamma was zero. At the angle of alpha 25 °, using wedges, we apply a lemeh onto a sheet and make a point welding from 2 sides.

The rack shield is also joking with the lemche. The junction occurs in a vertical position, the edge of the shield enters the edge of the lemis by 5-8 mm. The shield must be higher than the lemis blade (above the steel sheet) by 6-10 mm. The indent is needed for unhindered cutting with the lemmet of the soil.

Dumping with the lemmet is joined tightly, without gaps. Their design should be one. The angle between the lemhery blade and the upper edge of the dust should be in the limit of 6-8 °.

Figure - 7 drawing of plow details.
Figure 8 - Fastening the plow lemis.

If the molding of the lemis with the dump does not coincide with the parameters, then the desired angle of the hammer give the right. After fitting, the rear of the back clutches with the lemche and the side shield welding. After, the side shield is welded with a spacer plate and a base plate. At the end to the plate, stubborn corners for the lemum are grabbed.

After point welding, inspect the plow if all the necessary parameters are sustained, welded. Steel sheet, which was welded to a plow, separate from the housing with the help of a grinder or hammer and chisel. Give the design to cool and after clean all the welds. The surface of the lemis and duck clean the sandpaper.

Setting the Plow.

Setting up in several stages. But first you need to twist nuts on the mount, but at the same time you do not delay them. Then it is necessary to fix the unit with the fastening of the stitch of the motoblock, using two metal pins. Everything can be moved to the setup, it is performed in several actions:

1. Motoblocks put wheels on a flat surface and carry out balancing;
2. With the help of special bolts, an angle of inclination of the plow is exhibited. Note that the "heel" of the plow at the same time should be parallel to the surface of the soil;
3. Now the motoblock can be removed and put on the ground. The steering wheel should be at the level of the pahahar's lumbar;
4. The last setting step is the assessment of the correct configuration.

Video homemade plow for the motoblock.

Probably such a problem arises from many gardeners and gardeners. Available little plot Earth is one or three weave, and it needs to be pumped. Shovel Murotno, the horse is nowhere to find anywhere, the tractor will not enter. Buy what a cultivator for a piece of bucks and use it for an hour a year - presses the toad. He began to dig through the spaces of the Internet - was it really a manual plow, only our invention - and what came up with greedy bourgeois?

It turns out that bourgeois such a device existed for a long time, but they used it only for subsequent improvements of the Earth - superficial cultivation, shallow crimping, the manufacture of furrows when landing. That is, to manually pull the plow along the turne instead of a horse with two people, this is not observed there. Probably better to fall off in the district of several owners and buy a motoblock. So the collective farms and socialism appear, which is also not happy. But how they plowed; Women in the Dutch field 1919. Make a manual plows of grooves for landing poppy:

Hand plugs with large wheels at the beginning of the 20th century were made almost in bulk:

According to the same principle of bourgeois, manual cultivators did.

Now let's stop on our needlewomen. In connection with the frequent need of manual plugs, they began to produce almost every factory. The designs of such a product are almost identical and are intended for use as rated the Great Association, which will make it, and the parents will help. It looks like this:

These structures are constantly being improved by both enterprises and folk craftsmen. Rollers and discs are set, either a rope or a pipe with cross-country are used in the form of thrust. Frame from a bike can be used:

Very interesting Belarusian homemade, I liked the shape of a hand plow - Okootper:

In parallel with such searches, the ancient American manual lawn mower found. Everything is primitive - a pair of knives, two wheels. And the manual harrow of old cowboys. Maybe someone will try:

Here he is a drawing of a hand plow:

Buying a motoblock, we often cannot acquire all attachments to it. For example, the price of the mounted plow is from 800 to 6000 rubles. Such a difference in prices is due to the type and quality, the various complexity of the execution of plows. And it is not always possible to buy what we need. Tools made with your own hands are much smaller. Therefore, let's look at how to make a plow for a motoblock with your own hands. With drawings, with explanations.

Plows are invented and created a lot. On the panstones Enough to use such:

• one-poultry;
• revolving;
• rotary.

Singlepussian - The most common, it is easy to handle. Anyone who does not have skills will be able to work with him not familiar with the process of mechanized plowing. There is a lot of information on the network, how to make a self-made plow for a motoblock, drawings to it. This disposable is not very difficult to do.
Reverse - It is well used on solid soils. It has a curved shape. Due to this, the land is plowing in such a way that the reservoir turns over. This plow make it harder. It is necessary to have skills to work with such a labor item to properly make the product.
Rotary plow Even more difficult than revocable. It consists of several Lemekhov, walking on each other - on one axis. Scrolling axis. The layers turn over. Due to physical inertia and progressive movement, the process of plowing is facilitated. This processing makes it possible to effectively make the uninstall to 30 cm. In depth. A rotary plow with your own hands has another plus: you can make a dispenser along any trajectory, not only in a straight line. A plot with oblique or curvature edges by this device can be patched as you like. Naturally, it is convenient.

How to make a one-circuit plow

Such a plow looks approximately this way. Do not necessarily have a wheel near.

There is a single-door without wheels:

It is necessary to do, thoroughly obstructed, thinking in advance drawing. Here is an example of such a drawing:

A layout made of solid cardboard, completely identical in size and forms of the plow. If the layout succeeds, then it is duplicated from steel. Steel must be chosen alloyed, 3 mm thick.
When the steel form is cut, the problem arises, how to make a lemch of the peculiar oval screw form. Stamping form at home and even in a workshop is problematic. Therefore, again we make a shape of thick cardboard, now just direct. After that, cut (grinder) steel shape neatly on steel strips. Note every strip. Cut the cardboard form exactly to the same strips. Note. Experiment with a fold and gluing (tape, tape) of the bands so that the curved and glued bands accepted, repeated the form of the first cardboard model. We study the position and bending of each strip.
We carry out an operation on bending, twist - already steel stripes. Alternately, welding the twisted stripes and twisting with a layout. We use vice and infridate tools. When Lemeh is ready in black, carefully grind the place of welding.
Now about the LEMEX knob that below. For him, he needs hardened alloy steel. It is desirable to do it removable so that you can take off and change to ready-made, sharpened. So more convenient. Fresh knife on short durable secret bolts. Three hint bolts under the end key from the blade side is enough.

LEMAGE MANUFACTURE

It was a variant of the most sophisticated way to create a single-populated plow. There are methods simpler, but working.
There is a way of making a lemhery from the pipe. In the drawing, which is higher, it is indicated. For the manufacture of a simple spacker is suitable. Only for an exclusive, powerful plow version of the manufacture of pipe will not go. Opportunities to give the desired form less. A bent piece from the pipe can only be warm and bend, try to achieve the desired form. One-piece metal is difficult to bend in household conditions, even heated.

There is a simple way, but quite effective for shallow plowing. The image of this method is given in this picture of the shopping plow for the motoblock.

You can perform this in your own manually. Two steel blanks are cut on the desired form. They need to bendled, cook under a bevelled corner. The lower part of the main side of the square is to rejoice in a big hammer, give the form. Make a blade. Close to blade bolts. Find a metal square rack. To arrange it from the inside of the sideline of the lemis, drilled everything and strengthening bolts.
To the top of the rack perpendicularly, it is addicted to the square craving, which will connect the unincarnis with the motor-block. So that the plow can be adjusted in the depth of plowing (above, below), on the sides of the thrust to weld two strong plates with two bolt holes. In the rack, drill holes under the bolts. In a row - above, below the rack. Fresh traction through the paintings of the plates with bolts with nuts on the rack. The product is ready to work.

Singleproke plow zykov

On the Internet you can find a popular one-plow plow zykov, drawings, sizes for its execution with your own hands. That's what it looks like:

Such a form of Lemeh can be given, working with a large hammer and gas burner for warming up metal. Thus, this model is famous - efficiency and simplicity. Here is a drawing:

How to make a swivel plow for a motoblock

The easiest way is clearly presented in this image:

Rack. Two lem humans are welded on it. One - Cutting. Other (top) - turning and leaving the land. At the top, to strengthen the stiffness of the lemis overturning land, the corner is welded, resting in the upper edge of the tipper. Stiffness is observed. We see the store version.
When independent execution, you can change, make it better and easier for rearrangement of plowing depth. Coast, which is associated with the rack bolts, you need to cook with a plow. To make it all long. No box that in the picture is not needed. To the crossbar in front to adjust the bracket, in which one more vertical rack should be strengthened. A small but sufficient to get out of the zone of the turning land.
In this vertical small rack (square shape), drill several holes for the bolts. Through the holes at the desired height, the thrust coming from the motor-block at a right angle. The thrust is attached to this front rack with two welded plates with eye pieces. Two bolts are inserted and attached nuts. They are connected to one whole traction and rack.
This connection is easier and efficient. And the plowing depth can be adjusted. You can also here so that the Earth can not stick in the interval, between the top and bottom of the lemmet, the slim sheet of tin. This additional factor will help the earth to go smoothly and quickly along the arc and turn over to the reservoir.

Swivel plow zykov

Now consider another one swivel plow - Zykov.

Here, the strengthening of the lemhehs is made by strips of steel on bolts. And at the top, and below - at an angle. A good design solution of the increase is implemented - reducing the distance between the upper and lower lemchom. Simple and economically. A tail with a welded device holds two lemishes with racks, laid in the device. Two locking bolts hold a knot of ligaments. For the stability of the plow on the chassis, the wheel is traditionally.

"Motoblock in a pair with a transport cart (thanks" M-K "!) I smeared. And now take-bring something on the household for me, as they say, is not a problem. But a good plow still did not get. I am waiting for a detailed material on the pages of such a magazine, a thorough thing about how such a plow is to calculate and do. Similar requests wishes comes to the editors a lot. Apparently, from those subscribers who failed to familiarize themselves with the previous speeches of the magazine on their item you are interested in (see, for example, M-K 1'88, 3'89, 9'90, 5'91, 10'91). And therefore - a new publication dedicated to the ancient and, as the life itself is evidenced by the powerful tool of the landpash.

The invention of the plow historians refer to the end of the fourth millennium BC. It was then that was guessed to use a pointed strong bitch for loosening soil. Hence the word "Sokh", which translated from Sumerovsky means nothing more than the "pahacary tree". And the metal tip to this tool was invented in ancient Egypt, having obtained, in fact, the dealer with a sole formed by the horizontally supplied by the lemche, but not having a duck. The latter appeared in the design of the plow only during the time of the Roman Empire and is clearly in no hurry to take the conquered positions (see illustrations).

With all the diversity of technical solutions laid in it, the modern plow consists mainly of the working bodies, auxiliary nodes and mechanisms. The knife (disk, as shown in the figure, or a cutlets reproducible by the magazine earlier, see, for example, "M-K" 5'91) cuts off the soil reservoir equal to the width of the body capture. The Certifier removes the top layer covered with vegetable residues, weeds and their seeds, puts it on the bottom of the furrow formed at the previous passage. The housing is cut down from the bottom of the reservoir equal to the width of its capture, takes it off from the non-discharged field, turning and crumbling, moves to the side and resets into the furrow. Soil bunch behind the housing is fringed with a layer of soil, without throwing it to the surface. Well, the auxiliary nodes and mechanisms provide all technological process Plowing, performed by the working bodies (in this case, three) guns.

In a small-sized agricultural machinery (mini-tractors, motoblocks), only the housing is used from the working bodies above. Yes, and the number of auxiliary nodes and mechanisms in order to simplify and reduce the cost of plows are often minimized. How it is done, for example, in the design published in No. 4 of the journal for 1984.

The lemch and the blade of the housings form its overall leverage-dumped surface of a certain geometric shape. As practice shows, an important task - choose it optimal optionBased on the technological requirements of tillage, kinematic and energy conditions, as well as the real possibilities that the developer and the manufacturer of the Plow has. Up to construction materials, the presence of machine equipment, gasoelectrics, mini-shabby, etc.

1 - Knife, 2 - Certifier, 3 - body, 4 - soil bunch.

1 - cylindrical. 2 - Cultural (transitional), 3 - half-welded, 4 - a screw surface, 5 - a housing with replaceable breasts. 6 - cut, 7 - disk, 8 - roller, 9 - with rotor.

1 - trapezoidal, 2 - bit-shaped, 3 - with a welded cheek in front, 4 - toothed, 5 - with retractable bit.

1 - cylindrical, 2 - screw, 3 - cylindridoid types.

1 - trapezoidal, 2 - twisted.

1 - the base ("driving" the LEMECH of the factory production), 2 - tooth welded sink (segment of a spring leaf from the car ZIL-150), 3 - tooth of the welded straight line of the lemheh (from the refrigerated springs from the car GAZ-51, 2 pcs.).

1 - Duck worn (from the refined PP-40 or another plow), 2 - the defective part, 3 - the scan of the self-made plow.

Many stop their choice on a general purpose plow. And try to use the housings with cylindrical (see figure), and the cultural leverage-dummy surface. When plowing, such plows are well crumble, but not fully wrapped the layer. Therefore, it is used mainly for processing old-phase soils, which medium strip Russia, as you know, is not deprived.

The housings with a semi-shine leverage-dummy surface are better wrapping, but the layer looser is worse. They are used for the processing of hidden marriage, dried peat and swamp soils. Cases with screw leverage-unscrewed surfaces plow virgin, seal, meadow and other heavy soils, as they turn the plastic well. Significantly less often turn to housings with replacement breasts, cut, disc, with a rotor, etc.

Each of the above-mentioned structures has its advantages. And accordingly, its drawbacks. For example, the roller dump reduces friction losses, but it is composed on the device. And high-speed dumps of other buildings in a number of high-speed places are more intense, it turns out, crumble the soil, it is more densely put it on the surface of the field, which in turn leads to a significant increase in energy consumption.

Or take the lem. The greatest distribution, as statistics shows, the trapezoidal and chopped structures were obtained (see illustrations). Working in difficult conditions, cutting off the reservoir of the soil and directing it to the dump, they are rapidly wear out and break. Toothless lemroys are harder in the manufacture. But they reduce the traction resistance of the case, since the reservoir requires a significantly less effort than the soil section. For work in particularly severe conditions, lemmes are used with a welded cheek in front. And when processing particularly dense soils or a deep smell of good results show lemmers with retractable bit. All this is impossible, naturally, not to take into account. As, however, the differences in the structures of wild boards and racks of the enclosures due to certain requirements or conditions of operation.

And further. It is easy to see that the plow hull is based on (see illustrations) Tri-marginal Wedge Avo, the parameters of which are largely determining when designing a specific design, giving it those or other operational and technological properties.

In particular, the angle A, located in the longitudinal-vertical plane, contributes to the bending and clarification of the soil reservoir. With the help of an angle in the cross-vertical plane, the layer turns around. And the angle y, located in the horizontal plane, contributes to the movement of the latter to the side. In this case, the reservoir bends properly and crumble. The indicated parameters of the triggered wedge are interconnected by trigonometric dependence:

Consequently, here you can arbitrarily change only two angle, and the third is determined by the values \u200b\u200bof the first two. The output for the designer is important. As, however, the fact that the three-way wedge under consideration, depending on the change in its parameter, can acquire the leverage-dumped surface of the plow housing of a certain type (see illustrations): cylindrical in the development of angle A, screw with an appropriate change in angle in and cylindridal - with the development of angles A and B in standard plow enclosures. Their geometric parameters developed for serial motoblocks and mini-tractors, we strongly recommend adhering to the design of homemade motor components:

There are several practical methods for constructing the leverage-dust surfaces of plow enclosures. The simplest of them involves the movement of the horizontal forming of AB on two guide parabolams 1-1 'and 2-2', which are arranged in the plane of the walls of the furrow and in the plane parallel to it at the distance of the width of the body capture. To select the parameters of the guides, it is necessary to specify alone values, while others determine the calculated or experimental way.

In particular, it is established: some parameters of the Plow hull depend on the width of the processed formation, the specific resistance and density of the soil, the speed of movement, and a number of other factors. Based on this, the length of the lemum with sufficient accuracy is determined by the ratio:

When calculating the plow, another no less valuable, according to the testimony of specialists, the ratio, according to which the width of the capture in the designed body should exceed the possible plowing depth of 1.5 times. This is necessary for normal turnover of the formation. The application in the design of the Certifier leads to a decrease in the most mentioned fraction. But on small-sized tillage tools, the claims, as already noted, are usually not used. And it should naturally take into account.

Armed with the above prerequisites and mathematical formulas, you can develop plows, to the maximum extent that meet modern agrotechnical requirements, characteristic features Specific small-sized technology, a soil-climatic zone. The beginners are also recommended to keep the geometric parameters of the serial prototype, as well as samples manufactured to industrial mini-tractors and motor-blocks of structures.

Of course, there is no blind copying of the plow that you like for one or another reasons. Including the finished developments from those successful structures, which at different times appeared on the pages "M-K". But it is better to approach the case creatively by taking the ideas of the most interesting technical solutions. For example, the shape of a cutlery knife, field board and a leverage-dust surface with relevant tabular data, as well as the principle of operation rotary mechanismpublished in the fifth issue of the magazine for 199) year.

A lot of valuable can be found, say, from the design of a self-made plow, the body of which is made from the old, clamped with the uncertainty of the Certifier with the welded steel plates (see "M-K" 3 / B9). And how interesting will it find a novice Samoreppy (and not only) in the material published in the number 1 of the magazine for 1988, where with sufficient completeness outlines the method of making a lemhery, duck and supports of a removal of segment ... 550-mm pipes!

To the one who is familiar with blacksmithing works, it is quite possible to fulfill excellent, it is necessary to say, the lemhery from the worn, but having a metal reserve on the back side. The required sizes and configurations are achieved here by the hot logging (dimensions L and L1 - see illustrations - calculated) and forging delay. For this purpose, the lemche was placed on the mountain and slowly heating his blade to a width of 70-80 mm to a temperature of 500-600 ° C (before the advent of the glow), after which the heating rate is gradually increased. It is adjusted to 1100-1200 ° C (light yellow color). Moreover, not to subjected metal hazard danger, prevent disorders between the grains of steel and increase its fragility, it is usually heated only that section of the lemhery, which is currently subject to hardware or delay. The rest of the surface is falling asleep with fresh coal (to reduce heat losses and at the same time in order to prevent carbon burning from the surface layer of metal and, consequently, to reduce its hardness).

LEMEX TAGE stops as soon as the temperature decreases to 800 "C (light-fishing color). After all, otherwise cracks may appear. Therefore, in order not to allow the repeated heating harmful to metal, they try to delay the lemhery "without wires". Then work on the finishing of each of the sections of the future product can be performed from one heating.

During the delay, the curvature of the surface of the lemhery is changing. Speak sometimes fasteners in it. Therefore, the product needs to be adjusted forms, which is usually performed on a concave mandrel with a shank strengthened in anvil. Mandrel is made according to the new Lemeh. The curvature of the surface is installed on the lumen between the blade and the stove: there must be about 3-5 mm in a minor product. As for the displacement of the mounting holes, it is eliminated by precipitate on the end and the corresponding edge of the lemis.

The drawn, but did not cooled still lemche clap in the vice and wash it with the blade. And the cooling - sharpened on the sandpaper with the front (working) surface. The width of the ribbon (chamfers) should reach 5-6 mm, the thickness of the blade is 0.5-1.0 mm. And you do not need to sharpen it. Otherwise, it is possible to block the blade when quenching, and in the process of work - choking.

To quench the lemeh, he is heated to 50-840 ° C (light cherry color) along the entire length of the blade for 1/3 width. After the back is lowered down into the salted (1-1.5 kg / l), heated to 30-40's water. And the frail lemeh before immersion in the salt solution also needs in additional cooling. It is performed in order to avoid cracks, for which at the place of the transition from the blade to the sock is applied for 2-3 seconds a wet cloth.

And one more, this time already overall for both types of lemhery, feature. To reduce the fragility of the product after hardening, spend a vacation at a temperature of 350 ° C followed by cooling in air. The degree of heating here is judged by the color of passion.

Hardening quality is determined by a file: it should not leave noticeable on the eye of the tracks on the blade of the lemis. This corresponds to 444-653 bringel units. After checking the hardness of the blade control the straight line of the lemhery.

The design of the lemis is very promising. After all, it works on plowing dry soils 7-10 times longer than standard. Moreover, the teeth are made from the thrown automotive springs and are welded to the base (the front side) at the same distance from each other (see Figure). The angle of inclination of the front edge of the teeth to the cutting edge of the 4V ° blade. Sharpening teeth top, at an angle of 45 °.

Cutting down teeth from spring sheets is facilitated by heating the latter in blacksmith Horny to a temperature of B50-1000 ° C (orange color). It helps heat treatment and in the exercise of the self-delicent of another no less valuable idea: the manufacture of dust from the bundled thorough body of the serial plow (see illustration). As practice shows, they will not be superfluous, unclaimed and other knowledge and skills. So dare, and your hardworking, perseverance in achieving the goal will be rewarded by a hundredfold.
