[0002] Glutinous corn is an important food crop. Compared with traditional food crops such as rice and wheat, it has strong drought resistance, cold resistance, barrenness resistance and excellent environmental adaptability. As a high-yield food crop in my country, glutinous corn is an important source of feed for animal husbandry, breeding, aquaculture, etc. When processing glutinous corn, it is usually cleaned in advance and then sorted.

[0003] In the existing corn selection device, dust easily accumulates on the surface of the conveyor belt after long-term use, which affects the cleanliness of the corn. When the conveyor belt needs to be cleaned, it is usually necessary to stop the conveyor belt for wiping, which affects the processing progress. In addition, the existing corn selection device usually adopts a single selection design. This selection method will cause some unqualified corns to be mixed with qualified products, affecting the qualified rate of the finished product. Therefore, the utility model provides a device for quickly selecting the size of corn to solve the problems raised in the above background technology. Utility Model Content
