Corn threshing and slag removal device

Abstract

The invention discloses a corn threshing and residue-removing apparatus including a threshing portion which includes a first cylinder body, a first threshing mechanism and a second threshing mechanism, wherein the first threshing mechanism and the second threshing mechanism are arranged in the first cylinder body and arranged from one side to the other side in order; the first threshing mechanism includes a plurality of pressing assemblies, a sieve plate, a screw type conveying spring, and a motor; the second threshing mechanism includes a roll shaft pair, a conveyor belt, and a separating portion; the separating portion includes a second cylinder body and a residue-removing portion; and the residue-removing portion includes a snakelike pipeline, a drawing fan, and a residue collection box. The corn threshing and residue-removing apparatus realizes the separation of corn kernels and corncobs by carrying out two-stage type threshing on ears of corn. The corn threshing and residue-removing apparatus realizes the separation of corn kernels and granule residue bodies as well as corncob residues by carrying out two-stage type residue-removal on the ears of corn. The corn threshing and residue-removing apparatus has the advantages of hygiene, energy conservation, convenience, high threshing efficiency, and good corn kernel quality.

Description

technical field [0001] The invention relates to the field of agricultural machinery. More specifically, the present invention relates to a corn threshing and deslagging device. Background technique [0002] Corn is the third crop in my country after rice and wheat, and crop harvesting is an important link in agricultural development. The corn thresher is a kind of agricultural machinery, mainly used to separate the dried corn kernels from the corncobs. [0003] A conventional corn threshing device includes a drum-type threshing part arranged in a closed frame body, a sieve-type separation part surrounding the threshing drum, a cleaning part composed of a sieve plate and a fan, and only the feeding port and the The discharge port is the entry and discharge of corn. But there are still some problems: (1) Threshing part: the motor drives the rotation of the threshing drum at high speed, and the corn collides with the threshing drum to thresh, which will inevitably crush a sm...

AI Technical Summary

Problems solved by technology

But there are still some problems: (1) Threshing part: The motor drives the rotation of the threshing drum at high speed, and the corn collides with the threshing drum to thresh, which will inevitably crush a small part of the corn cob, resulting in more impurities in the processed corn kernels , need to carry out several times of filtering and sorting; (2) separation part: the existing sieve is a plane sieve, and the corn kernels and miscellaneous materials coming out of the threshing drum will continuously fall on the sieve, and the sieving speed is lower than the accumulation speed, resulting in A large number of corn kernels accumulate on the surface of the sieve, which greatly reduces the working efficiency; (3) cleaning part: the fan can only remove the dust, but not the crushed corncobs, resulting in a large amount of impurities in the obtained product
