Corn threshing device

Abstract

The invention relates to the technical field of agricultural production, in particular to a corn threshing device. The corn threshing device comprises a threshing device body, a first rotating roller, a second rotating roller and a collecting frame, the first rotating roller is installed in the top end of the threshing device body, and the second rotating roller is installed at the top end of the threshing device body through a bearing; and a driving mechanism is arranged on the surface of the second rotating roller. According to the corn threshing device, a scraping rod and a filter plate are arranged, falling corn kernels can be screened and collected through the filter plate, large-particle impurities or crushed corn ears can be separated from the corn kernels, and the situation that after the corn kernels are threshed, a large number of impurities mixed in the corn kernels are difficult to clean can be avoided; by arranging the scraping rod, impurity corn kernels on the surface of the filter plate can be scraped, so that the situation that the corn kernels are accumulated on the surface of the filter plate, blockage is caused, the corn kernels cannot be separated clearly, the filtering efficiency of the corn kernels is affected, and too many corn kernels exist in a dust discharging opening is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a corn threshing device. Background technique [0002] Compared with traditional rice, wheat and other food crops, corn has strong drought tolerance, cold resistance, barrenness tolerance and excellent environmental adaptability. Corn has high nutritional value and is an excellent food crop. In the process of processing, it is necessary to peel off the corn kernels. Generally, a corn thresher is used for threshing. The corn thresher refers to a mechanical device for threshing corn ears, mainly for threshing the dried corn ears. It is easy to operate, simple in structure, sturdy and durable, reliable in operation and convenient in use and maintenance, so it has been welcomed by farmers for many years. When the existing corn threshing device is in use, a large amount of corn ears needs to be put into the threshing device, but when the instantaneous feeding amount o...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the prior art that when the instantaneous feeding amount of corn ears is large, the feed port will be blocked, and the threshing device will not clean the corn ears and the corn kernels will produce a large number of broken and corn kernels. There will be a large amount of impurities or broken ears of corn, which will cause the sieve surface inside the threshing device to be blocked, making the separation of corn kernels unclear, and the dust outlet will also discharge a large number of corn kernels.
