Influences of Main Parameters on Performance of Seed-Filling Device in Plot Seeder

Abstract:

Seed-filling device of plot seeder is the research object. Influences of the four test factors (motion velocity (v), rotation speed of filling device (ω), generatrix length of seed-filling device (l), base angle of seed-filling device (α)) on the uniformity in seeding-filling process for wheat seed are analyzed by DPS7.05. The effect order of four test factors on wheat seed is obtained. Optimum parameters for wheat seed established are as follows: motion velocity of plot seeder 0.4m/s, rotation speed of seed-filling device 0.25rad/s, generatrix length of seed-filling device 0.1m, base angle of seed-filling device 50º. The best plot length for the seed-filling device is 10m and the best CV in seed-filling process for wheat seed is 7.85% when seeding rate for wheat seed are 180g per plot.
