The oscillations of the movable fingers 3 are made from the cam as the drum rotates. The movable fingers 3 are connected via a collar 8 by a spring 9 with a washer 10. Ploughshare 1, undermining adjacent rows, serves a layer on rotating drums 2, which crush and

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to working bodies of root-harvesting machines. ;

The purpose of the invention is to increase productivity and reduce clogging of the working bodies, leafs and plants with J and residues.

FIG. 1 shows a sub-separating and separating device, side view; in fig. 2 - the same, top view; in fig. 3 is a section A-A in FIG. one.

The tilting and separating device contains plowshares 1 for undermining potato wedges, followed by drums 2, which are perpendicular to their plane; they provide; the wives are driven by a drive mechanism; 0 are rotating and have rotation bodies, in concave form; The generators of which are placed by poche-i red mobile 3 and fixed 4 fingers. Based on drum 2, you-; filled in the form of a bar ring, the lower ends of the mobile fingers are pivotally connected, rigid fingers are fixed. The upper ends of the fixed fingers are rigidly connected to the disk 5, through the grooves of which the upper ends of the mobile fingers pass. On diametrically opposite two mobile fingers, above the surface of potato wedges, cutting elements (knives) are installed.

The oscillations of the movable fingers are made from the cam disc 6 when the drum rotates in the bearings 7 mounted in the machine body. The movable pins 3 through the collar 8 by the spring 9 are connected to the washer 10.

A separator transporter 11 is installed behind the reels.

The paping-separating device works in the following way.

When the potato harvester 1 is moving, two adjacent rows of potatoes are broken in. Drums, turning towards each other, crumbling

shift it on. separating conveyor 11. At the same time, the vegetation and tops are wound on the drum, raised to the cutting knives of the moving fingers, which, with their vibrations, cut them and move them to the separating conveyor. 3 il.

undermined reservoir and move it to the separating conveyor 11. In this case, the moving fingers, rolling over the cams of the disk 6, vibrate, which improves the crumbling of the soil.

The springs 9 with the connecting washer: 10 provide a constant, even contact of all the moving fingers and cams, and the grooves, the disk 5, serve on; they are the guides for moving the moving fingers.

Crumble additionally improves; with because of the shape of the fingers of the drum. Tiny soil through the gaps. Between: drum fingers are sifted on; the bottom of the furrow, and the tubers and plant residues are transported to a separating conveyor .;

With the rotation of the drums movable; in the process of vibration, the fingers approach and are retracted to the axis of the drum, and the position of the fixed fingers is constant. As a result, the surface of the drum periodically takes on a corrugated shape, which improves its separation capacity. At the same time, the vibrations of mobile Yalevs exclude the sticking of the soil to the surface of the rods in the inter-bar spacing.

Plant and other vegetation; winding on the drum, due to the conicity of its surface, rise up to the cutting knives and at the time of sliding the moving fingers with the knives are cut and fed to the separator conveyor 11.

Claims (1)

Invention Formula An undercutting and separating device of a root-harvesting machine, which contains plowshares, behind which are spacers rotating towards each other, the lateral surfaces of each of which are formed by fingers, characterized in that. in order to increase productivity and to reduce clogging of the working bodies of the tops and plant residues, the upper end is made in the form of a disk, the diameter of which is less than the lower end, made in the form of a ring, the fingers have a concave shape, and their connection with the ring is carried out but alternately rigidly and articulated with oscillation in radial vertical planes, with the upper ends of the moving fingers mounted in the spring-loaded grooves of the disk, and at least two diametrically opposite fingers in the upper part are provided with cutting elements. eleven  / ten
