Threshing and deslagging integrated device for corn

Abstract

The invention discloses a threshing and deslagging integrated device for corn. The device comprises a threshing part, a separating part and a deslagging part, wherein the threshing part comprises a horizontally arranged box body and a first threshing mechanism and a second threshing mechanism; the first threshing mechanism comprises a plurality of pressing assemblies, a supporting plate and a plurality of rotor drums; each of the pressing assemblies comprises an air cylinder and a needle head; a bottom plate is hinged to the bottoms of the rotor drums; a sensor is arranged on the bottom plate; the air cylinder, the rotor drums, the bottom plate and the sensor are connected with a controller; the second threshing mechanism comprises a roll shaft assembly and a conveyor belt; the separating part comprises a barrel body, wherein a space where corn kernel roll is formed between the barrel body and the box body; the deslagging part comprises a serpentine pipeline, an exhaust fan and a dust box. By threshing the cobs in two sections, corn kernels and cobs are separated; the cobs are deslagged in two sections, so that the corn kernels are separated from small particle slag body impurities and cob impurities; the device has the advantages of being sanitary, energy-saving, convenient, high in threshing efficiency, good in corn kernel quality and the like.

Description

technical field [0001] The invention relates to the field of agricultural machinery. More specifically, the invention relates to an integrated device for corn threshing, dust removal and slag removal. 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 wi...

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
