Description

For the threshing of corn cobs, the industry produces corn flakes and augers with corn hammers.

The proposed corn thresher is an original device. The food in it is designed for the organized supply of corn cobs from the bunker to the working chambers. The threshing process is performed in six chambers, due to the action of a finger pin drive system together with bevel gears.

Pa drawing shows a diagram of the thresher (side view and nlan).

The thresher consists of the following main components: a receiving conveyor, a feed mechanism, a threshing device, a screen and a fan.

Above the upper working branch of the receiving belt conveyor / is located oscillating with a brush-type grating 2 with a hopper 3.

The feeding mechanism consists of six feeding corrugated rollers (coils) 4 mounted on one shaft and six conical

gears 5, also mounted on the same shaft, as well as guide snails 6, spring-loaded plate unregulated springs 7 and spiral adjustable springs 8 with an adjusting thumb 9.

The threshing apparatus consists of four finger discs 10 and / / located on the same shaft and isolated from one another by three hollow partitions 12, which divide the threshing chamber into six separate threshing chambers. On the disc 10, fingers for threshing are placed on one side, and on disks // on both sides. Under the disks 10 and // there are arcuate decks (troughs)} 3, which prevent the spillage of corn kernels and serve as guides when moving the peeling products (threshing) to the upper screen of the J4 roar.

The screen consists of the upper plate M to the bottom sieve 15. The fan 16 is placed under the belt conveyor and injects a stream of air flow into the threshing chamber and under the screen.

The threshing process is as follows. Corn cobs are loaded through hopper 3 onto a belt conveyor. Inserting sieve 2 ensures that the cobs are evenly distributed and flow along the conveyor 1.

The speed of movement of the belt and the yro; i slope between the conveyor / and the sieve 2 may vary. From the conveyor belt 1, the shelters enter the feeding mechanism, where they are turned, and the cochlea 6 rotates with them for threshing from all sides and provides a feed at a certain angle to the frosting chamber.

The threshing process is performed in six threshing chambers by acting on the cobs of a finger-drive system of 10 m 11 bevel gears 5.

From the threshing chambers, grain and threshed cob rods through decks 13 enter the upper sieve of screen 14, the rods remain, and grain spills onto the lower screen of screen 15. The crushed cobs of corn, finely crushed corn and other small impurities are removed from the sieve 15 by air flow the blower fan 16, and the whole grain flows down and enters the tarpaulin, or bags.

Subject invention

Claims (2)

1. Mo; a corn fork consisting of a pickup boot, a belt conveyor, a threshing drum with a screen and a fan mounted on a wheel frame, characterized in that there is a multi-section oscillator above the belt conveyor with a grille and a grooved roller providing combined with a guide snail, organized feeding on the cobs of corn by working chambers formed by three partitions. 2. The form of embodiment according to claim 1 is distinguished by the presence of a system of rotating discs with fingers on the end surfaces located in the working chambers, which, in cooperation with the guide snails and conical scabies, produce threshing of corn cobs.
