Be machine's turn to have mainly enter expect that the mouth , bars form notch board and nail tooth the cylinder threshing and drive component etc. are composed of. Take electric motor as driving force source, driving force exports axis output from the electric motor , the nail tooth seed-husking cylinder threshes on the cylinder threshing again by the fact that belt delivery arrives at the nail tooth, coordinating bars form notch board with the corns, besides seeds complies with bars form notch board separation and the outside discharging airframe, but the maize core discharges airframe from another one end entering material.Its process flow :The corn ears though hopper entering the threshing device, under the high speed rolling cylinder which installed the nails crash and the corn ears squeeze with the notch board, the seed will be drained. Than drained seeds will through the board slipped outside. Cob drained outside under the spiral nails help.In oder to make corn ears fluently entering the body ,and can not clog th the body ,the steel board of the bottom of hopper, should be designed set a angle .The corncob escapement should maintain certain distance with the grain escapement, in order to avoid the corncob and the grain are mixed.Corn threshing's production efficiency decides in the necessary power size. Its power dissipation may be possible to escape 600~1000kg according to the 1kw.h merit to dial the corn skin computation. That has not skinned when directly the corn carries on the seed extraction, its productivity approximately is 30%~50%.
