Description

Threshing by wiping or squeezing the seeds with a stationary and rotating high surface of two drums is used in machines for threshing of some industrial crops, such as peanuts, equipped with a drum rotating inside a cylindrical surface.

The peculiarity of the proposed mologil; a1 consists in applying the method; 1a squeezing the corn cobs by iix between the rubberized working surfaces of two, inserted one into the other, conical drums of different sizes, arranged vertically with smaller bases of the cones down and eccentric to each other, moreover, the inner drum rotates from the engine, and the outer drum is fixed non-strung on the thresher frame. A simple and original thresher scheme provides a productive and high-quality technology for threshing corn cobs without damaging the grains.

The drawing shows a thresher in a section The thresher consists of two drums that are inserted one into the other and have the shape of a truncated cone. The outer surface of the inner drum / and the inner surface of the outer drum 2 are upholstered with a rubber strap or rubber 3 and 4. The drums are located vertically, smaller than the axis; the tips of the cones are down, 1 eccentric to each other. The inner drum rotates, and the outer drum is fixedly mounted with the smaller base above the hole of the frame lid 5. With the larger base to three legs.

The inner drum is seated on a square shaft 6, along which it can move in a vertical plane to adjust the gap between the tapered surfaces. The retaining ring 7, mounted on the shaft, ensures that the inner drum is fixed in height in a vertical position. The shaft rotates in two double-row sub-supports 8 and 9, fortified in brackets 10 and //. Between the bearing housings and the brackets there are rubber pads 12 and 13 and pcL "111564

pads, through which regulate the gap between the surfaces of the drums. The upper bearing and, consequently, the inner drum is spring-loaded with two springs 14 with a force of 15-20 kg each. Springs l. rubber pads give the internal drum the flexibility needed to avoid jamming the cobs. The inner drum receives rotation from the electric motor / 5. Corn cobs are loaded into the receiver 16, 2-3 pieces at a time, at any time, manually. The cob, hitting between the walls of the drums, occupies a vertical depression and is pulled through, turning around its axis into a narrow gap between the conical surfaces, where the extrusion of the corn grains takes place. or another container. The cob, uninscribed in the first turn, is lowered down between the walls of the drums and subjected to repeated grinding. The threshed cob falls through the gap between the walls of the drums in the lower tea cup, onto the pitched board, and leaves the sieve. In the case of a sturdy cob between cones, the inner drum will move away, the springs will be squeezed, the cob will turn and no jamming will occur. Springs and rubber pads protect the grain and cob from crushing.

Subject invention

Thresher for threshing corn cobs, excl. and with the fact that, in order to eliminate the damage of the grains and the best threshing of the noodles, a method was used to squeeze the grains out of them by passing:; l between the rubberized working surfaces of two, inserted one into the other, drums of different sizes, located vertically, smaller bases of the iKopnycoB, and eccentric from each other, aspta, one other, and the inner drum rises from the engine, and the threshing wheel is fixed to the thresher frame.
