大多数谷物条播机排种器采取外槽轮式,它具有构造简单、通用性好、播种量稳定、各行播量一致性好、播量调整方便等特点。但使用时间长了,排种器的阻塞套和排种槽轮接触面,发生磨损及偏磨,出现空隙。造成播种机排种量不稳,各行排量不一致,破碎率升高,从而影响了排种质量,所以应及时修理。 Most of the cereal seed drill seeders take the outer wheel, it has the advantages of simple structure, good versatility, stable seeding rate, good consistency of seeding lines and convenient sowing adjustment. But the use of a long time, the blocking device of the seeding device and seeding sheave contact surface, wear and partial wear, there gap. As a result, the seeder displacement is not stable, the row displacement is inconsistent and the rate of crushing increases, which affects the quality of the seed, so it should be promptly repaired.
