Description

Universal elevator potato diggers are known, consisting of copying rollers, base elevator, elevator-separator, topper-removing elevator with pressure conveyor, and pon-river conveyor.

In contrast to the well-known 11ed.lozhp universal elevator potato digger, D of which, in order to increase its separation capacity, the elevator-separator is equipped with an agitator operating independently of the linear speed of movement of the e.vovator web and made in the form of an eccentric shaft, shatuni and levers that transmit vibrations to the rollers mounted under the elevator web.

. In order to carry out the selection of tubers from a swath, in the proposed potato digger, selected swaths are used, mounted instead of plowshares.

The drawing shows a diagram of a universal e. Chev; 1 torn () go potato hoekeepers.

The potato digger consists of two plowshares /, the main elevator 2, the elevator 3 with active shaking, the topper-removing elevator 4 with the forward conveyor, the transverse conveyor 5 n copying rollers 6. In the case of the selection of tuber lancers. In place of the plowshares / mounted rotating rollers are fitted.

The work of the proposed potato digger is as follows.

During the movement of the potato digger, two piles of potatoes are being undermined simultaneously by two flat wedge-shaped sharers and the boat mass is fed to the main elevator 2. At the main elevator 2, the soil is separated from the tubers.

No. I4J0262

Tubers, tops and remaining from the soil enter elevator 3 with active shaking. Klubn and soil lumps pass through: 5, and a grain elevator, and the tops, hanging on its rods, are pressed against the conveyor and taken out behind the machines. The tubers left on the leaves are stripped of the baffle rods and fall down the elevator.

At the elevator, vigorous separation takes place by active shaking, since its oscillation frequency does not depend on the linear velocity of the elevator web, and the separating surface of the elevator is not covered by tops. The shaking mechanism of the elevator 3 is made in the form of an e.Syntric shaft, a hatch and levers preventing oscillation of the rollers mounted under the leaf of the equipment, and h D1I1ZHONI1 from the power output shaft of the tractor.

K iyrtfiii from the head of J i stand on iaierschny eleator 4, which pushes the tubers out of the machine and puts them in a row 300-500 mm wide from 2, 4, 6 or 8 grades, depending on working conditions and condition of the floor.

This is done by moving the conveyor in the transverse direction. Under optimal working conditions, the proposed potato digger yields potatoes with small admixtures of soil clumps up to 13% and plant residues up to 11%, so the tubers can be tared immediately.

The advantage of a potato digger is that they can harvest potatoes on light, medium and heavy soils. When working on light soils, it can be used as a combine with an additional cleaning of the tubers from impurities when sorting potatoes.
