to machines for harvesting potatoes and root crops. The purpose of the invention, the reduction of damage to the root crops. The machine contains installed in series the plowshares with sidewalls 7 and the ripper of the reservoir, containing a rotating shaft 5 with half-disks 6, installed with a circumferential displacement. The half-disks of 6 elliptical form are isggy with their small axis. When moving the car sidewall 7 pruned the soil along the edges of the beds, and eliminate the collapse of the reservoir, digging up the plowshare. The undermined reservoir enters the separator and is exposed to a ripper, which, with its half-discs 6, loosens the reservoir, shifting the soil alternately in different directions. 2 Il.

The invention relates to the industry

agricultural engineering,

in particular, for potato and root harvesting machines.

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

Figure 1 shows schematically the separating device of a root-harvesting machine, side view; figure 2 is the same, top view.

The machine contains successively installed undermining passive or active sharers 1, a seam ripper 2, a separating grain elevator'3 with 1G shaker 4 of its web. Above the ploughshare 1 or the place of transition, the ploughshield is set to a ripper of the formation 2, which is a rotating shaft 5 with half disks 6 installed with a circumferential displacement. The latter are formed by bending at an angle (ώ) or (180-ώ) to the shaft of the ripper of an elliptical-shaped disk along its small axis. Angle (οζ) can vary in the range of 20 ... 35 °. The projection of a curved elliptical disk on a plane perpendicular to the axis of the shaft, has the shape of a circle, the Ploughs have sidewalls 7.

The machine works as follows.

When moving the machine, the sidewall 7 cuts the soil along the edges of the beds and eliminates the collapse of the seam undermined by the plowshares' 1. The undermined formation is exposed to the ripper 2, which half-disks 6 actively loosen the formation, shifting the soil alternately in different directions, destroying lumps and leveling the tuberiferous formation along the width of elevator 3. The half disks, in contrast to solid discs, make not only two but four displacements of soil in one turn of the ripper (figure 2), i.e. half the amount of soil is moved, and the amplitude of soil movement by half disks is half the size of soil movement by elliptical disks, which reduces the likelihood of potato tubers being crushed and stones sticking between half disks 6 and sidewalls 7. Shaker 4 additionally intensifies the process of soil separation. At the exit from the elevator, 3 tubers are cleaned of adhering soil with brush elements of the cleaner.

Claims (1)

Claim Separating device of a root-harvesting machine, containing a separating elevator and a ripper in the form of a transversely placed shaft with loosening elements of elliptical shape, set at an angle to the axis of its rotation and at different angles to each other, characterized in that, in order to reduce damage to the roots , loosening elements are made in the form of half-disks placed offset from each other on the circumference of the shaft by a half-disk, each half-disk having an elliptical shape being curved along its minor axis. 1366094
