| Abstract: |
| For improving the seeding quality of cole, exploring the best parameter for Spiral Wobble Wheel Seed Metering Device, by using EDEM analyze the speed , diameter, position of different type of seeding device; defined the relationship between speed, diameter of the whirling hole, rising angle and the seeding quality. Simulation results showed: when the speed was 30 r·min-1, whirling hole diameter was 3 mm, and the rising angle was 59.31°, the qualification rate was over 93.7%, missing rate by 1.3%, reseeding rate was 5%; By increasing the speed, will decrease the qualification rate, and increase the missing rate, reseeding rate as well as variation figures. According to the variance analysis, the order of the significance among those factors was first speed, second whirling hole diameter and then the rising angle. Because of the highly matching of the simulation results and the field experiments proved that it's possible to use the method of the discrete element for analyzing the Cole seeding machine. |
