Corn crusher

The utility model discloses a corn crusher. The corn crusher comprises a shell and a breaking mechanism in the shell, wherein the breaking mechanism is connected with a drive motor via a connection rotation shaft and comprises symmetrical movable and fixed tooth plates, and movable and fixed teeth distributed on the movable and fixed tooth plates along an axial direction; the movable teeth rotate relative to the fixed teeth; and the movable and fixed tooth plates are made of wear-resistant hard alloy materials. By virtue of the breaking mechanism with the combination of a movable state and a fixed state, the concentricity of movable and fixed plate bases is ensured, the structure of the crusher is simplified, the time for maintaining a traditional mechanism is reduced and the labor strength is greatly reduced; and meanwhile, the service life of the crusher is prolonged due to the anti-corrosion materials.
