Description

Reversible plow

The utility model relates to agricultural engineering, in particular to plows for smooth plowing with laying seams in one direction when moving the arable unit by shuttle.

The reversible plows of the German company Lemken and the Norwegian company Kverneland are known, which are a fixed part mounted on a tractor and a revolving frame pivotally connected to it with a right-handed one mounted on it1; and left-turning housings (Prospectus Lemken Gmbh Co KG Weseler Str. 5. D --10519 Alpen Kverneland Klepp AS N-4344 Kverneland Norway from the international exhibition Agricultural Machinery for Farmers held in St. Petersburg in 1999). In the plows of the indicated manufacturers of the Opal, EurOpak, Vari - EurOpayuh m models Kvernet-land LB Variomat revolving frame ZsKreg ;. ; it appears; -: and the cantilever part of the shaft mounted in ball bearings of the fixed part of the plow, mounted on a tractor.

Domestic reversible plows for smooth plowing of the PNO-3-35 type are also known (Catalog of agricultural machinery, edited by V. Chernoivanov Scientific Research Institute of Information and Scientific and Technical Research. M., Informgrotech, 1991, v. 1, p. 133) and plows according to the patents of the Russian Federation No. 2084090 and No. 2109418, having similar designs of articulated joints.

Distinctive features of the proposed utility model of a reversible plow from those indicated above is an increase in the reliability of the articulated joint and an increase in the same frame.

This is achieved by the fact that the fixed part of the plow has longitudinal bars with hinges at the ends, connected to the transverse beam, and the hinge fingers are fixed in racks mounted on the crossbars connecting the longitudinal bars, and the movable hinge bushings are fixed - one on the cross member of the revolving frame and the other on the hull beam in place before it intersects with the longitudinal plane of symmetry of the fixed part of the plow with the possibility of rotation of the revolving frame relative to an axis located in this plane, with the supporting or support A non-transport wheel with a mechanism for controlling the depth of plowing is located on the longitudinal bars of the fixed part.

The reversible plow (FIG. 1) contains a fixed part consisting of a transverse beam 1, a rack 2 with fastening elements to the tractor attachment and longitudinal bars 3. A revolving frame consisting of a cross member 4 and a housing beam 5 is pivotally connected to the fixed part of the plow b hinges are fixed in racks 7 on crossbars 12 connecting the longitudinal bars of the fixed part of the plow, one at the point of their connection with the transverse beam 1, and the other at opposite ends of the bars 3. The movable bushings 8 of the hinges are located - one on each the list 4 of the revolving frame, and the other on the hull beam 5 connected to it in place before it intersects with the longitudinal plane of symmetry of the fixed part of the plow. Right-handed and left-handed plow bodies 9 (shown conditionally) are rigidly fixed on the hull beam. The reversible plow frame has the ability to rotate about an axis located in the longitudinal plane of symmetry of the fixed part, under the action of the rotation mechanism 10. The rotation mechanism 10 of the reversible plow frame consists of

a hydraulic cylinder connected by eyes with a rack 2 and a cross-beam 4 and hydraulic control elements. Hinges, consisting of fingers 6 and bushings 8, can be structurally combined into one hinge. On the longitudinal bruyah 3 mounted supporting (opornotransportnoe) wheel 11 with a mechanism for changing the depth of plowing.

The work of the plow is as follows: the fixed part of the plow using the fingers of the transverse beam 1 and the holes on the rack 2 is mounted on the attachment of the tractor aggregated with it, the hydraulic equipment of the plow is connected to the hydraulic system of the tractor. Using the mechanism for changing the depth of plowing, the distance between the supporting surfaces of the working bodies of the housings 9 and the support wheel 11 is set equal to, taking into account its pressing into the ground, the depth of plowing. When the tractor hinged device rods are raised to the upper extreme position, the plow mechanism 10 turns into the transport position, in which the hull beam 5 with plow bodies 9 is set to the middle position. The tractor and the plow aggregated with it occupies its original position before plowing.

At the beginning of plowing, on the left (in the direction of travel) side of the field, the revolving frame should be moved to the left extreme position, and the tractor hitch to the “floating. In this case, the plow will lower to the contact of its bodies 9 with the surface of the field to be treated, which should be followed by smooth movement of the tractor without jerking. The plow bodies 9 will go deeper into the soil until the support wheel 11 is in contact with the field surface, causing the layers to fall off with left-turning bodies. At the end of the aisle, stop the tractor, raise the linkage of the attachment and turn the frame 5 to the right extreme position with the rotation mechanism 10. Expand the tractor for passage in the opposite direction, set it relative to the plowed area, put the attachment in position

"Floating and start moving. The plow will roll out the layers with right-handed bodies until the end of the return passage. After that, all the above actions should be performed in the same order until the tillage of the field being cultivated is completed.

At the beginning of plowing, on the right side of the field, the revolving frame should be moved to the right extreme position and the actions should be performed in the same sequence, moving the arable unit by shuttle.
