Dynamic Analysis to the Seeds in Indent of the Indent Cylinder Separator

Recently, traditional rules of male sterile lines and restorer lines to regularization planting, with harvesting respectively, labor intensive, uneven pollination, and seriously affecting to the quality and yield of seeds, have been changed by the technology of Engineered Seeding Production, which can reduce the production cost and greatly raise the level of seeds breeding mechanization. But, there are also many problems, in particular, purity of the seeds and high working efficiency are hard to guarantee. So developing a separator is the crux of further popularization. On the basis of parents in different lengths, this paper designs a model Indent Cylinder Separator to study dynamics analysis, and obtains the factors influencing the results of separation are radius, angular velocity and rake angle of the cylinder. Meanwhile, mathematics models between structural, kinetic parameters of the cylinder and different lengths seeds are founded to provide theory basis for further study of structure and parameter design.
