A kind of permanent magnetic precision seedmetering device was designed. The seeding component was a cylindrical permanent magnet. According to the working principles of the permanent magnetic precision seedmetering,the model of seeds pickup process was established.A Matlab program based on this model was made. The influences of angular velocity, pickup angle, and relative coefficient of friction on pickup ratio were simulated and analyzed. Combination of optimal parameters was found. The relationship between pickup ratio and angular velocity, pickup angle, relative coefficient of friction were S type, exponential type and loglinear type. With the combination of optimal parameters, the pass percentage of seeding could reach to 97%.
