Description

Known universal hammer mills for the processing of corn stalks include a loading elevator with pick-up, a threshing and crushing device, a cleaning system with a lattice stand and a fan, a receiving hopper ic discharger, grain elevators, a conveyor for cobs of corn and a frame with running wheels .

In the proposed crusher, the threshing and crushing devices are interconnected by grain elevators through a chute that directs the threshed grain directly to the receiving hopper or to the crusher. This almost completely eliminates manual labor when loading the unit and unloading the recycled product.

The drawing shows the proposed grinder crusher. It consists of a loading elevator / with pick-up 2, a threshing 3 and a crushing 4 devices, a cleaning system with a mill 5 and a fan 6, a receiving hopper 7 with a unloader, elevators S and 9 for grain, a conveyor 10 for cobs. The threshing and crushing devices are connected by grain elevators through a pour-over tray 11, which directs the grain to the receiving hopper or to the crushing device.

The technological process of threshing corn cobs on seed and fodder grain proceeds as follows. The machine collides with a coil of cob, and the pick-up passes the cob to the loading

an elevator that transports them to the threshing device. Here, the cobs are grabbed by the threshing drum and pressed against the surface of the deck bars. Beale separates the grains from the rods. The bulk of the threshed grain and small impurities passes through the holes in the deck and enters the sieve of the cleaning system. The rods and part of the threshed grain pass through the sieve through the hole in the rear disk of the deck.

As a result of oscillations of the sieve mill, the corn grain passes through the sieve holes on the elevator 8. The rods descend on the sieve onto the conveyor, which mixes them to the ground into a roller on the left side of the machine. All light impurities are blown by the cleaning system fan away from the machine.

The cleaned grain is fed by an elevator to a tray, then to a crushed grain elevator and, finally, to a receiving bin, from where it is unloaded by a unloader.

The threshed grain, to be crushed, is directed by the chute to the crushing device. From there, through a replaceable sieve, it is fed to the elevator of the crushed grain, and from there to the receiving one (bunker.

To crush the coals of milky-wax ripeness into a silo, a replaceable sieve is replaced with a deaf one, blades are installed on the working disk, the cover is removed from the crusher chamber pipe and the conduit through which the ground silage material is transported to it.

Subject invention

The threshing crusher is universal for treating corn cobs, containing a loading elevator with pick-up, pick, threshing and crushing devices, a cleaning system with a sieve mill and a fan, receiving bin with unloader, grain elevators, a conveyor for cobs of cobs and a frame with running wheels characterized in that, in order to reduce the complexity of servicing the thresher-crusher and increase its hourly productivity, the threshing and crushing devices are interconnected by grain elevators through a tray, threshed grain directly into the receiving hopper or into the crusher bucket.
