Thresher based on differential inversion principle of corn ear grains

Abstract

A thresher based on the differential inversion principle of corn ear grains comprises a rack and a motor, wherein two vertical plates which are oppositely arranged on the rack are respectively provided with a corn ear clamping device and a threshing device, each threshing device comprises a roller and a belt wheel connected with one end of the roller and driven by the motor, one end of each roller is hung in the air, the end, hung in the air, of each roller is provided with at least two threshing components, and each threshing component is composed of a bolt arranged on the circumferential face of the corresponding roller in a penetrating mode, a fixing block connected to the bolt and threshing blades arranged on the fixing block; the other end of each roller is arranged on the center shaft of the corresponding belt wheel in a sleeved mode, a bearing in rolling fit with each center shaft is arranged in the corresponding roller, a hollow sleeve and a bearing end cover are arranged on each center shaft, and the two ends of each center shaft are respectively provided with a shaft end baffle. According to the thresher based on the differential inversion principle of corn ear grains comprises, through the threshing blades capable of being located in the line gaps of the corn ear grains, rows of grains are removed from corncobs, the grains in different positions of one core ear can be threshed at differential speeds through the same threshing blade, and it is guaranteed that the grains are totally separated from the corncobs.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a thresher based on the principle of differential velocity inversion of corn ears. Background technique [0002] Maize is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. Every link of corn cultivation, planting, picking, threshing, and transportation has a great impact on the next use of corn, and corn ear damage is inevitable in every link. Most of the existing corn threshing devices are threshing devices based on the principle of impact threshing, that is, the corn ears are threshed by the high-speed rotation of the rotor and the impact of the drum. Shock threshing has a certain damage effect on the grain. The damaged corn grain is stored in short-term or long-term, and it is prone to mold and insects. Moreover, the germination rate of damaged corn is low. The breakage ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem that the existing threshing devices easily cause grain damage, according to the growth and arrangement of the grains on the corn ears, the present invention provides a thresher that can reduce the damage rate of corn grains during threshing and is based on the principle of differential inversion of corn ear grains
