Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for separating impurities from root and tuber crops. The purpose of the invention is the reduction of damage and loss of roots. The device comprises a rotor 5 with elastic rods and a drum 2 with spiral winding 3, also mounted above the last belt conveyor, mounted successively over a bar conveyor. The elastic rods of the rotor 5 are made interacting with the working branch of the belt conveyor and the spiral winding 3 of the drum 2. During operation, the rotor 5 rods presses the vegetable impurities to the winding 3, which are then clamped by the belt conveyor and carried out of the device. 2 Il.

The invention relates to agricultural machinery and can be used in machines for harvesting and sorting of roots and vegetables.

The purpose of the invention is to reduce the damage and loss of root crops.

FIG. 1 shows a device for separating impurities from root and tuber crops, side view; figure 2 is the same, top view.

The device consists of a separating conveyor 1, above which are located a drum 2 with spiral winding 3 and a fender roller 4, rotating in opposite directions to the movement of the working branch of the separating conveyor. In front of the drum 2, in the zone of action of the spiral winding 3, a rotor with elastic elastic rods 5 is installed, having the opposite direction of rotation relative to the rotation of the drum 2 and the possibility of independent movement of the axis in the horizontal and vertical planes due to screw 6 and 7 or other mechanisms. A belt conveyor 8 is placed above the drum 2 with spiral winding 3, covering the upper part of the lower branch, while the ends of the elastic rods 5 contact both the conveyor 8 and the winding 3. Next to the separating conveyor 1, there is a subsequent working member 9 on which it moves processed mass using spiral winding 3.

The technological process of separation of impurities is carried out as follows.

A heap containing soil impurities, root crops, tops, and other plant impurities enters the separating conveyor 1. Some of the small impurities, the dimensions of which are commensurate with the separator conveyor slits, are sieved through these slots, and the remaining portion of the heap is fed to the separation conveyor branch 1 to a spiral winding drum 2 3. The elastic rods 5 of the rotor of the tops and other plant matter are pressed against the working branch of the conveyor 1 and in this state they pass into the gap between the turns of the winding 3 and the conveyor 1 to the baffle roller 4, which does not allow the roots to go beyond the separator, and the impurities are removed from the device; Unsolicited soil lumps and roots are moved by spiral winding 3 along the axis of the drum 2 to the next working element 9. Plant impurities, raised

the surface of the heap spiral coiling 3, fall under the action of the elastic rotor rods, which are pressed back to the winding 3 and fed into the pinch zone,

formed by a belt conveyor 8 and winding 3, where they are trapped, and then carried out of the separating device. The degree of compression of the pile to the working branch of the separating conveyor and plant residues to the spiral winding of the drum can be changed by moving the rotor axis in the vertical and horizontal planes. Koroblubneplody, rebounded as a result of exposure to

they spiral coiled 3, fall on the elastic rotor rods and return them back to the winding 3, which gradually moves them to the subsequent working body 9, and then drops it onto it,

large soil impurities (lumps) also move there.

Removal of long vegetable impurities with such a device already on the first separating conveyor significantly

improves the separation process on subsequent working bodies. Technological failures of the device due to the loading of the pile in front of the spiral-wound drum and on the subsequent working bodies, due to the absence of vegetable impurities, are significantly reduced, and the damping of the rebound rate of the root-and-vegetable crops by the elastic rotor rods and the avoidance of their impact with harder working surfaces.

organs of the separator and among themselves reduce the damage and loss of root and shrub crops.
