Homemade cultivators. Homemade cultivator for motoblock

Technical support in the farm of a modern farmer necessarily includes means for cultivating the land. For this purpose, cultivators and motoblocks are used, which depending on the model can perform tasks on loosening, leveling, weed cutting and other operations. Since the device of the working organ is technically elementary, it is not difficult for a skilled home master to make such a device with his own hands. As a rule, self-made cultivators are not inferior in efficiency to factory analogues, but it is important to calculate the ways of their installation on a motor-block or tractor. However, today manual models are also common, the operation of which does not require connection to other equipment.

General information about cultivators

The term "cultivators" in many associates with minitractors and motor blocks that perform the functions of soil cultivation. However, if you delve deeper into the terminology, it turns out that the cultivator is only a part of the technical equipment directly involved in the processing. Depending on the design, self-made cultivators can perform several operations. They can be versatile in both processing and in combination with optional equipment. Before you start making such a tool, you should evaluate the nature of the work and the need for its connection to a tractor or other equipment.

Hand cultivator with own hands

The simplest version of the cultivator at home. This is a small design, the capacity of which is enough to capture a strip 20 cm wide. The base of the device will be a handle in the form of a metal tube with a diameter of 2.4 cm. The length of the element is selected specifically for the growth of the user. On the lower part of the pipe it is necessary to install a solid axle made of wood. The processing organs will be attached to it. Despite the simplicity of the design, self - made hand cultivators can be supplemented with wheels. They can be cut from a metal sheet 0.3 cm thick and fixed using nuts.

There is another version of the design, assuming a base in the form of a strip of spring metal. In this case, the workpiece parameters should be as follows: length - 5 cm, width - 2 cm, and thickness - about 2 mm. A wooden handle is attached to this part, through which processing will be carried out. The tape is bent, so it can be shaped like a loop, then double-sided the edges with a file. The diameter of the loop can be any, this parameter is calculated based on the area of the garden.

Rotary disc cultivator

This is a more serious unit, with which you can perform both loosening, and leveling the soil, and hilling. In its construction, the cultivator homemade hogweed assumes the presence of the following elements: a disk, an axle, a rod and bushings, large and small staples, a handle and a pipe. The functions of the working components are performed by disks welded to the bushings. The latter, in turn, are placed on the axis of the cultivator. Axial endings are fixed in brackets with the help of a cotter pin. In a large bracket in special grooves a pipe with a crossbeam and a handle is installed. A rod with a length of 25 cm and a diameter of 2.4 cm is installed on the smaller bracket (by welding).

Also in the rod is screwed a rod 1.6 cm thick, which should protrude slightly above the level of the crossbar. The most difficult thing in making this model is to make the discs spherical. In general, this is a common question among gardeners and summer residents interested in how to make a self-made cultivator with reliable working elements. Without special equipment, there can be only one way - to change the shape of the discs with a hammer, forming a bowl in the central part. Next, it is important to calculate the angle of fixation of spherical discs with respect to the processing direction. This parameter should be adjusted with the help of thumbscrews mounted on the crossbar.

Chainsaw Cultivator

This variety of self-made cultivators is also suitable for larger scale works. By its capacity the device will not yield to some versions of minitractors. In addition, it is possible to make a self-made cultivator for a motor block from a chain saw by providing the appropriate connection points in the structure. But a more profitable solution is a fully mechanized unit with a motor from a chainsaw.

The basis will be a cubic frame welded from the corners. The power plant will be located on the transverse corners in the upper area of the body. The tank with fuel can be installed even lower with the help of brackets. The front pillars will act as the supporting frame for the middle shaft. To fix the running gear bearings, the posts should be attached to the longitudinal members. As a result, you will get a homemade motoblock, whose center of gravity will be above the surface with a wheelbase. As a wheel, you can use a rubberized roller, and handles made of pipes.

Cultivator from the electric meat grinder

In this case, the power unit is borrowed from the meat grinder, but otherwise the concept remains the same. The frame from which self-made cultivators for a tractor or a motor block are made can also become a base for autonomous machinery. A feature of this design is the ability to quickly break up soil layers into large clods. If the operation is supposed to be at a low speed, the treatment will be delicate and will provide a loose cover.

It is necessary to weld two corners to the crankcase of the reducer removed from the meat grinder. They are also installed two pipes, which must first be bent end - in the future they will become handles. The axles of the wheels are also attached to the base of the corners. Excessively large wheels should not be chosen, because in the process of processing they will bring unnecessary trouble. But small ones are undesirable, because they fall into the soil. Accordingly, the best option - medium-sized wheels with a diameter of 20 cm. From the scrap you need to cut the shaft. With the help of a sledgehammer or a large hammer, it is necessary to sever the nozzle of the meat mincer, which will allow the bushing to be removed, which will accept the shaft with the claw screw.

Motor milling by one's own hands

This unit is a cross between manual models and a full-time motoblock. If you want to get a self-made cultivator, the cutter of which performs processing without a third-party drive, then this option will be optimal. Any installation with a working volume of 50 cm ^{3 is} suitable for the engine. The tasks of the cutters can be shifted to a structure assembled from metal strips with parameters of 0.5 x 4 cm. For one cutter, 8 elements are needed. Next, the strips need to be shaped like the letter G and connect them to each other in the center with bolts so that four crosses are formed.

The carrier base is a metal box, in which the reducer deceleration should also be placed. This frame can be made from 0.4 cm thick plates and bearing housings. To pass the intermediate shaft at the top of the formed box, two holes must be made. The shaft will rotate in two bearings mounted in two welded plates from the plates. To adjust the positions of self-made cultivators with this design are supplied threaded studs. They can be welded to the base of the plates.

Lancet cultivator

The unit has a simple construction and does not require a combination with other equipment, but it does provide good results in the processing of the land. The output is a lancet equipment with five working paws. The base of the structure will form a rocker frame, also made of steel corners. It is equipped with flat-cutting paws of the pointed type. Take such elements can be from the factory-mounted KPN-4A. The cutting components must be fixed in such a way that one middle and two last paws are staggered. Their bracing should provide a hinged frame on the springs. The assumed width of processing with such paws is 33 cm.

Disc harrow for cultivation

The disc harrow can be constructed from a battery formed by 8 discs that have a spherical shape. According to the type of work it will be a self-made cultivator for the motoblock, the width between the cutting elements will be 15 cm. With the frame, the harrow interacts on the hinge principle. The length of the base can reach 130-140 cm, and the width - 65 cm. In this case, the corners are used for corners with a cross-section of 45 x 45 cm. The depth of penetration into the soil is up to 10 cm, and the approximate width of capture is 120 cm. To the merits of such a harrow It is also necessary to include the possibility of adjusting the angle - up to 17 degrees.

Single-hull plow

One of the best solutions for making auxiliary equipment for the tractor will be a single-hull plow. With its help for an hour of work, you can plow from 0.12 to 0.2 hectares. The depth of processing is small at this, only 22 cm, and the width reaches 35 cm. Homemade cultivators for a mini-tractor made of a metal frame base are manufactured. The plow can be made of channels, and the body can be borrowed from a trailed attachments such as a lopper, but with a shortened blade.

Conclusion

Constructional solutions for the development of cultivators are many, and the choice of concrete is determined by the requests of the future user. The material costs of manufacturing land-cultivating devices are minimal, and this despite the fact that factory analogs are sometimes estimated at tens of thousands of rubles. This largely accounts for the fact that self-made cultivators are increasingly being used not only in private farms, but also in professional farming organizations. On reliability, they are slightly inferior to branded units, and the quality of processing the land can and exceed. It is possible to make a cultivator with your own hands from improvised metal blanks, but the main advantage of such devices is the ability to diversify designs and, if necessary, make technical adjustments without the help of specialists.
