Study on Seeding Performance of Rape Seeding Device of Socket-roller

The test method of seed quantity、seeding uniformity、broken rate and seed quantity of per revolution is introduced in this paper. and the relation curve between the speed of seeding device and seed quantity、seeding uniformity and broken rate is attained by the test. It also analyzes that the speed has the influence on seed quantity、seeding uniformity and broken rate. The apiece row consistency of seeding quantity and the stability of full seeding quantity for this type of seeding device are attained in this paper. The suitable speed range of seeding device was got by the test.
