The main working part of the corn thresher is the rotor installed on the machine. The rotor is rotated at a high speed and hits the drum to thresh. The grain is separated by the sieve holes, the corn cob is discharged from the tail of the machine, and the corn silk and skin are discharged from the tuyere. The feed port is located on the upper part of the machine's upper cover. The corn cob enters the threshing chamber through the feed port. In the threshing chamber, the corn kernels fall off by the impact of the high-speed rotating rotor, and are separated through the sieve holes. There is a baffle in the lower part of the feed inlet to prevent falling The splash of corn kernels hurts people, and it is the most widely used economical threshing equipment. The new corn thresher has many advantages such as small size, light weight, easy installation, operation, maintenance, and high production efficiency. The corn thresher is mainly composed of a screen cover (that is, a drum), a rotor, a feeding device, and a frame. The screen and the upper cover rotor form a threshing chamber. The rotor is the main working part, and the corn is threshed. Just finished in the threshing room.
