[0002] Corn belongs to the Zea mays genus of the Poaceae family, with the scientific name Zea mays, commonly known as corn cobs, corn, corn, and corn. It is native to Mexico and Peru in Latin America along the Andes foothills. With the development of the world's shipping industry, corn has gradually spread to all parts of the world and has become one of the most important food crops. Corn usually needs to be separated during processing, so a corn threshing device is needed. The current corn threshing device mainly relies on the working parts to hit, crush, differentially rotate, squeeze or rub the corn cobs to destroy the connection between the corn kernels and the corn cobs, so that the kernels are separated from the corn cobs to achieve the effect of threshing and separation. However, some existing corn threshing devices require the user to put the corn and the device in a horizontal state when the corn enters the device. Because the corn that enters the corn threshing device horizontally has poor contact with the threshing working parts of the corn threshing device, it is easy to cause unclean threshing, which is inconvenient for the staff to use.
