前言近年来我国在铺膜播种机上采用滚筒式排种装置的日益增多,这种装置中的种子是随滚筒(种子室)一起转动的。目前对其中的种子流动规律及其影响因素探讨还不多,为此,我们通过试验观察种子流动的情况并作初步的运动分析,为进一步选取排种装置的最佳参数提供参考。种子相对于滚筒运动的情况,直接影响到取种器取种和分种的能力。为此,我们对旋转 In recent years, our country in the film-seeder with roller-type seed metering device is increasing, this device is the seed with the drum (seed chamber) with the rotation. At present, there is not much research on the law of seed flow and its influencing factors. Therefore, we observe the flow of seed through experiments and make initial kinematic analysis, which will provide a reference for further selecting the best parameters of seed-setting device. Seed relative to the drum movement, a direct impact on the ability of seed seeders and seeds. To this end, we are rotating
