摘要
本文按“零速投种”的要求,通过对种子在导种筒内几种运动可能的分析,从理论上找出影响种子在导种筒内的相对速度的主要因素以及相对速度的数值范围,为播种机导种筒工作曲面的设计提供了计算方法和设计步骤。
In accordance with the requirment of Zero-Speeding, this paper has theoretically figured out the factors affecting the speed range based on the analysis of several possibilities that seeds move along the seeding tube, paving the road to a desirable calculation method and design procedure of the working surface curve of the seeding tube.
