It is to remove the grains of the harvested crops from the ears, and at the same time separate other removed materials such as short stalks, husks, and debris from the grains as much as possible. Corn is the crop with the highest total output in the world and has always been known as a longevity food. Corn is rich in protein, fat, vitamins, trace elements, cellulose, etc. The process of threshing corn requires the use of a corn threshing device.

[0003] A search revealed a Chinese utility model patent publication numbered CN221203392U, which discloses a corn threshing device comprising a base plate, the base plate being provided with a placement structure for placing corn; the placement structure comprising a support rod mounted on the base plate and a first electric telescopic rod, the telescopic end of the first electric telescopic rod being provided with a second electric telescopic rod, the telescopic end of the second electric telescopic rod being provided with a mounting rod, one end of which being provided with a blade; and a threshing structure being provided on the base plate for threshing the corn.
