Multifunctional corn thresher

The utility model discloses a multifunctional corn thresher, this corn thresher threshes to the maize through the rotation of axes of threshing to effect through the spiral plate tooth is moved the dextrad gradually, and the corncob pushes the movable plate, makes the corncob get into the blanking pipe through the corncob export and smashes and get into the corncob collecting box, is favorable tothe sparingly required parking space of corncob, and the corncob after just smashing can also be collected in order to make his usefulness, saves the resource, the kernel of corn passes through fan screening, gets rid of impurity, is favorable to avoiding because the increase of wasting time and energy of containing in the kernel of corn that the extra clearance of impurity needs causes and cost of labor improvement production efficiency, kernel of corn after the edulcoration gets into spiral helicine discharging pipe to carry out particle size's screening at the removal in -process, the quality is hierarchical simple
