Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry, particularly to working bodies for loosening and slotting the soil. The subsoil cultivator comprises a vertical rack consisting of two rigidly connected parts. The upper part of the rack is provided with a curved front edge in which lower part a hoe is located symmetrically. The lower part of the rack is tilted back in the direction of travel of the machine and has a chisel in the lower part. A tube of rectangular cross-section is put on the upper part of the rack with a gap. The lower part of the rack with sharp ground cutting edge tilted back in the direction of travel of the machine is welded to the tube.

EFFECT: constructive implementation enables to improve the reliability, working capacity, and to reduce metal consumption of the subsoil cultivator.

Description

The invention relates to the field of agricultural engineering, in particular to the working bodies for loosening and slitting soil.

Known working body of the deep-ripper [1], containing a vertical stand, consisting of two rigidly connected parts: the upper with a curved front face, the lower part of which is symmetrically located paw, and the lower, deviated backward in the direction of movement of the machine and having a bit in the lower part.

The disadvantage of this working body is that the lower rack is rigidly attached at the bottom to the back of the upper rack. This reduces the reliability of the design, because the force transmitted from the bit maximizes the bending moment of the upper strut relative to its attachment to the unit frame. In addition, when adjusting the working body to a different depth of loosening (because on different soils in structure, the plow sole lies at different depths from the day surface), it is necessary to remove the lower stand and replace it with a similar one, but with different geometric parameters (longer or shorter) . This reduces operational performance and increases metal consumption, as you must have in stock several interchangeable lower racks of various sizes.

The technical result of the invention is to increase reliability, operational productivity and reduce the metal consumption of the deep-ripper.

The specified technical result is achieved by the fact that on the frame a rigidly fixed upper strut with a front face in the shape of a parabola, having a paw in the lower part, is equipped with a lower strut with a chisel, which allows relative movement along the vertical part of the upper strut and is fixed with a locking bolt.

A comparable analysis with the prototype shows that the inventive device is characterized by the presence of a vertically moving lower strut.

Thus, the claimed device meets the criterion of "novelty."

The combined use of the upper rack with a curved front side, in the lower part of which there is a paw, and the lower, deflected back, having a chisel and allowing relative movement along the vertical part of the upper rack, leads to increased reliability, operational productivity and reduced metal consumption of the subsoiler.

This allows us to conclude that the technical solution meets the criterion of "significant differences".

The invention is illustrated by drawings, in which two figures are presented. The figure 1 shows a subsoiler, front view; figure 2 is the same side view.

The subsoiler contains an upper rack 1, the front face of which has the shape of a parabola. A paw 2 is located symmetrically relative to its longitudinal axis 2. A pipe 3 of rectangular cross section with a locking bolt 4 is put on the vertical part of the rack 1 (FIG. 2) with a locking bolt 4. A lower column 5 with a sharpened cutting edge is welded to the pipe 3 back in the direction of movement of the machine and having a bit 6 in the lower part.

Subsoiler works as follows.

With the movement of the paw 2 loosens the soil to a depth of 15 cm with the formation of a finely lumpy structure, and the bit produces coarse deep loosening at a depth of 15 to 35 cm with the destruction of the plow sole. To adjust the working body to the required processing depth, just release the locking bolt 4 and move the lower rack 5 along the rack 1 up or down.

This arrangement of structural elements can improve the reliability of the working body, because the fastening of the lower rack to the upper is moved higher and on the rack 1, the bending moment decreases; increase productivity due to faster tuning to the required processing depth; reduce metal consumption due to the uselessness of interchangeable lower racks of various sizes.
