Compared with prior art, the invention have the benefit that
null1、The present invention uses the methods of threshing of ripple threshing，It is to innovate based on the threshing under bionical thinking，Observe and find，On corn ear, the gap between longitudinal two row seeds is moved towards to approximate zigzag，But the corner angle of sawtooth can damage seed，Therefore the actual zigzag size to corn kernel gap carries out curve fitting and obtains the threshing unit of ripple，Seed will not be caused damage by this shape，The threshing band being made up of some threshing unit is similar to ripple，Therefore this methods of threshing is referred to as ripple threshing，The principle of ripple threshing is that ripple threshing unit is inserted in the gap between two row seeds，The ratio engaged with seed gap is more complete，The triangular shape side of seed can be close on the N-Side surf of ripple threshing unit，Contact area is bigger，The intensity that seed is born is less，Therefore the damage to seed is minimum，Ripple threshing unit produces lateral pressure by rotating to seed，Therefore seed is taken off from fruit ear；
2, the present invention uses the bionic principle of first discrete rear threshing, traditional manual threshing corn seed is first to wash out string seed with awl, grasp corn ear the most again to rotate and rub and taken off by seed, this threshing is summarized as the principle of first discrete rear threshing, discrete tooth in the present invention discrete can take off a small amount of seed, the transmission of power between corn kernel is interrupted, it is simple to the threshing of ripple threshing band；
3, the taper threshing cylinder of the present invention designs based on differential principle, enter vertically into and between the corn ear of cylinder and the cylinder of high speed rotating, form obvious differential, threshing band and discrete tooth are distributed in around seed, by differential action thus seed is taken off between ripple threshing band and seed, the inlet diameter of cylinder is more slightly larger than complete corn ear, single corn ear can only be accommodated enter vertically into, this brand-new drum threshing is similar to people and holds the process of corn ear rotation threshing, there is good low damage Threshing, and outlet diameter is less than the corn ear diameter diameter more than corn cob, this being designed to ensures that the corn cob only purified can from outlet out, it is effectively guaranteed the percentage of thresh；
4, the conical drum of the present invention has novelty on works, devise the shaftless cylinder of gear elongate support formula, by engaging each other between master bevel gear and secondary bevel gear, cylinder is fixed up, secondary bevel gear serves and supports and the effect of transmission, and cylinder can be stably rotated under the mating reaction of bevel gear；
5, the present invention can provide solution for realizing the low damage threshing of Semen Maydis, and this maize sheller has the advantage that breakage rate is extremely low, threshing performance is high, continuous core, principle are novel, and the threshing being not only suitable for conventional corn also is adapted for the threshing of corn seed.
