Abstract

The invention relates to the field of agricultural engineering, in particular to machines for harvesting root and field crops. The purpose of the invention is to increase the efficiency of supplying a buried tuberiferous stratum and cleaning the surface of the rollers. Digging device of the root crops contains rollers 1, undercut disks 2, plowing up plowshares 3, unit 4 for feeding a tuberiferous layer and separator 5. Each roller 1 has a central zone 6. Disks 2 are installed on one drive shaft 7 with a beater 8 which has elastic blades 9. When the device is moving along the rows, the roller 1 forms a clump. The disks 2 cut the soil layer along the edges of the bed, which, by the ploughshare 3, is cut from the bottom. Elastic blades 9 of the beater 8 rotate from the drive shaft 7, move the top layer of the tubers formation to the separator 5. At the same time, the blades 9 of the beater 8 clean the surface of the roller from sticking soil. 2 Il.

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 efficiency of supplying a buried tuberiferous stratum and cleaning the surface of the rollers.

FIG. 1 shows the digging device of the root and field crops; in fig. 2 is a view A of FIG. one.

The root-and-groove digging device contains rollers 1 for profiling a tubular trunk, undercutting discs 2, dropping pins 3, block 4 feeding the upper zone of the tubular reservoir and separator 5. Each roller 1 has a central zone 6. Disks 2 are mounted on the drive shaft 7. Between the adjacent discs 2 on the shaft 7 is fixed a beater 8 with elastic blades 9. The shaft 7 is provided with a drive element 10. Block 4 contains a drive shaft 11, a blade 12 and a drive element 13. The roller 1 and the beater 8 are arranged so that the sum of the radius R is cylindrical center noy zone 6 of the roller 1 and the radius r of the trajectory of the beater blades 8 9 exceeds the distance - of O | O2 between the axles of the roller 1 and the beater 8.

The device works as follows.

As it moves along the rows to be harvested, each roller 1 forms a tuber-bearing pile and draws in the soil. Each disk 2 cuts the soil layer along the edges and at the same time increases pulling force due to the forced rotation from the drive shaft 7. Ploughshare 3 cuts the tuberiferous layer from the bottom.

The elastic blades 9 of the beater 8 are forcibly rotated from the shaft 7, move the top layer of the tuberiferous formation towards the separator 5 and at the same time loosen it when it is fed. The blades 9 of the beater 8, while rotating, periodically meet the central zone 6 of the roller 1, clean the surface of the roller from sticking soil and simultaneously shake at the exit from the contact and self-clean from soil stuck to the surface. The tuberiferous stratum is fed to the separator 5 by moving the aggregate and acting on the upper layer by the blades 9 of the beater 8. At the entrance to the separator 5, the partially destroyed upper layer of the tubular stratum is fed forward by the blades 12 of the block 4.
