FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to potato harvesters.

A multi-potato potato harvester is known, comprising a frame mounted on support and running wheels, undermining organs, a sectional separation elevator, a device for separating impurities from tubers and an unloading conveyor I.

A disadvantage of the known construction is increased damage to potato tubers due to their prolonged stay on the cleaning bodies and overloading of the latter.

A pell of the invention is to reduce the damage to potato tubers by separating them into fractions after primary separation.

The goal is achieved by the fact that the device for separating impurities from tubers has a conveyor installed transversely to the separation elevator to separate the coarse fraction

tubers and separators placed in its contour with counter-directed feed.

In addition, the combine is equipped with a longitudinal conveyor with a pinnacle, the receiving part of which is installed under the unloading parts of the separators, and the driving wheels are placed in the gaps between the sections of the separating elevator.

FIG. 1 schematically shows a combine, side view; in fig. 2 - the same, top view} in FIG. 3 — view A in FIG. 2,

The multiply combine harvester contains support rollers 1, undermining organs — ribs 2, for which 1 rotating finger drums 3 are installed. Between the undermining organs 2 there are medium plowshares 4, and at each drum 3 rods 5 are placed to guide the tops to the rollers 6 pressed to smooth the surfaces of the drums 3. Behind the plowshares 4 there are sections of the separating elevator 7, the output parts of which are equipped with booms 8 and rollers 9. Transversely to the elevator 7 there is a device for separating impurities from tubers, which has a transporter 10 for isolating a large fraction of tubers and separators 11 with counter-directed feed placed in its contour. On the continuation of the conveyor 10 is installed on the upper conveyor 12.

A separating conveyor 13 and a finger slide 14 with a pick roller 15 are placed along the longitudinal axis of symmetry of the combine. The receiving part of the conveyor 13 is installed under the unloading parts of separators 11. A system of conveyors 16 and 17 is provided in the scheme of the combine to dispose of the small fraction of tubers. conveyor 13, intended for removal of soil.

The running wheels 19 are installed in the gaps between the sections of the elevator 7, and the supporting control wheels 20 are located at the rear of the combine. The cab 21 and the engine are fixed to the frame 22 above the driving wheels 19.

The combine works as follows. When the combine is moving, the rollers 1 copy beds and destroy soil clumps. The plowshares 2 undermine the pile and the drums 3 destroy the layer with their fingers and move the remaining mass to the middle plowshares 4. At the same time, the rods 5 send the tops and plant impurities to the target between the top of the drums 3 and the rollers 6 ,. who take them to the cleaned field.

From the plowshares, 4 tubers with impurities enter the elevator 7, which makes the separation of the soil. Plant impurities are removed by the joint action of rods 8 and rollers 9. Tubers with soil impurities enter the 1O conveyor, which separates coarse fractions of tubers and transfers them to the unloading conveyor 12. The fines and soil passed through the surface of the conveyor 10 to separators 11, which, continuing the separation of the soil, transfer the tubers to the conveyor 13. The latter brings the mass to the hill 14, which finally separates impurities from the tubers. The roller 15 reflects the tubers to the conveyor 16, which transfers them to the conveyor 17 and further to the conveyor 12. The flap 18 prevents soil impurities from getting onto the conveyor 16. The soil entering the flap 18 is removed by the lower branch of the IB conveyor. Separating a large fraction of potatoes at the beginning of the process reduces damage to them. In addition, the installation of the traveling wheels in the front of the combine allows the power units to be located in

the underflooding zone and, thereby, simplify the frame of the combine and reduce its metal intensity.
