出芽的水稻种子由于含水率较高,流动性差,芽容易损伤,故直播时难以保证较低的伤芽率.为了降低水稻芽种直播的伤芽率,根据振动改变物料特性的原理设计了一种振动式水稻芽种直播装置,并进行相关计算证明振动排种的可行性.同时以振动参数为影响因素,以伤芽率为试验指标,测定了伤芽率与其影响因素的关系.结果表明,选择振动频率为50Hz,振幅为0.8mm,振动倾角为4°时排种均匀性良好,且有效的解决了播种过程中幼芽损伤问题.

Abstract： The material feature of rice bud seeds are poor fluidity and the large angle of repose. And it is misfit the working condition in southern china hilly region. According to this situation, a Small Vibrated Seeding Apparatus of Rdce Bud Seeds was designed. And some Theoretical Calculation has been done to prove the feasibility of Small Vibrated Seeding Apparatus .And the test Used seeding rate work as the test index. This test indicated the relationship between the test index and the vibration parameter. The optimum V-shaped cavity amp...
