FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to machines for harvesting root and field crops.

The purpose of the invention is to increase the productivity and separation of the soil by eliminating the dumping of the excavated reservoir on the share and intensifying the separation process at the elevator.

Figure 1 shows the undermining working body, side view; figure 2 is the same, top view.

The machine consists of a plowshare 1, which serves for undermining the soil layer and installed with an elevated angle of lead 2 and driven 3 stars connected to each other by chain 4. frame 5, rigidly connected to the connecting rod 6. supports 7. fingers 8, cleaning their grilles 9 , Elevator 10, axis 11, rigidly mounted on a link in chain 4 and shnrnirno connected with the frame 5.

The machine works as follows.

Ploughshare 1 digs up the soil layer and crumbles it well due to the increased angle of inclination. However, an increase in the angle a leads to an unloading of the soil on the plowshare. The frame 5 with fingers 8 is designed to eliminate this. The front part copies the trajectory of the chain, and the rear part oscillates in a vertical plane.

When sprockets 2 and 3 rotate, chain 4, by means of an axle 11 mounted on it, carries frame 5 with fingers 8 fixed to it. to the elevator 10. Subsequently, during the bending around the axis 11 of the drive sprocket 2, the tine arms emerge from the soil layer and

move over the soil to its front position. The stems stuck on the tine bars are cleaned with the grid 9. The point of entry of the tillers into the soil layer is located at a distance of 1 / 2-1 / 3 of the toe of the plowshare, where a stable elevation of soil is ensured.

The hinge joints of the front part of the frame with 5 fingers with an axis 11, and the rear part with a support 7, allow movement of the fingers 8 along the path of the irregular ellipse while maintaining their plane-parallel arrangement of each relative in all phases of work.

The presence of a leading 2 and a driven 3 stars, spaced apart from each other at a certain distance, makes it possible to ensure stable soil transportation parallel to the upper branch of the elevator by the amount of this distance.

Bearing 7 has a mechanism allowing its position to be adjusted in a vertical plane, which makes it possible to adjust the angle of entry of the fingers into the soil.
