Influences of Working Parameters on Performance of Elastic-Friction Seed-Metering Device

Abstract:

The influences of the two working parameters of elastic-friction seed-metering device—motion velocity (v) and rotate velocity (n) on CV of seeding uniformity in the lines (v1), CV of seeding consistency between the lines (v2) and CV of seeding rate stability (V) are analyzed by two factors quadratic orthogonal rotational combination experimental design. With DPS 9.50 data processing system these mathematical models are set up. There is a very significant regression between v, n and v1, v2, V and all factors are significantly at level α=1%. The results show range of v1 is at 3.0996%-5.8912%, range of v2 at 4.1105%-5.9297%, range of V at 1.6274%-2.8504% in the values range of the two factors.
