Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to working bodies for extracting root crops from the soil used in root-harvesting machines. In order to reduce traumatizing of root crops, soil crushers 7 and 8 are installed in the working part of the Kopach with displacement relative to each other in the horizontal plane. When the working body moves progressively, the soil layer with the roots is grasped on both sides, and the dislocators of soil compaction 7 and 8 displaced relative to each other break the connection of the root crop with the soil. Moreover, at first, the linkage of the root crop with the soil of the lanyard with the soil crusher 8 is broken, which makes it possible to stretch the digging process, and then both the lemeshka with the soil crushers 7 and 8 loosen the roots and remove them from the soil without injury. Mutually shifted soil binders allow the digging process to be stretched and thereby reduce the injury to root crops. 2 Il.

The invention relates to agricultural machinery, in particular to working bodies for extracting root crops from the soil used in root-harvesting machines.

The purpose of the invention is to reduce trauma to the roots.

FIG. Figure 1 shows schematically the proposed working body for extracting root crops from the soil, side view; in fig. 2 - the same, in “d from above.

The working body for extracting root crops contains two-blade copacs, fixed on frame 1 by means of a hinge, containing 1 axis 2. Copacs contain paws 3 and 4 connected by a lever 5 to the drive mechanism 6. The inner working surfaces of the paws 3 and 4 are made at the same time with soil crushers 7 and 8, which are offset from each other.

The working body for extracting root crops from the soil works as follows.

Frame I is lowered to the working position, and lemepki 3 and 4 are buried in the soil to the required depth. The crank mechanism 5 and 6 is actuated, which provides for reciprocating and swiveling movements of the lugs 3 and 4.

At the displacement of the working body, the soil layer with root crops is grasped on both sides, and soil billers 7 and 8 displaced one against the other break the connection of the root crop with the soil, and at first the linkage of the root crop with the soil compaction destroyer breaks. This makes it possible to stretch the process of digging, and then both lemeshka 3 and 4 with crushers 7 and 8 soil loosen the roots and remove them from the soil without injury. At the end of the lemeshka 3 and 4 (where there is a minimum distance between them), the roots are extracted to the soil surface.

Mutually shifted soil binders allow the digging process to be stretched and thereby reduce the injury to root crops.
