摘要
建立了种子在滚筒内的运动微分方程，导出了种子的水平位移公式，从而确定出种子在下落时的初始位置——落种角（临界角）０，由此可在滚筒上配置接种漏斗或排种鸭嘴。
A differential equation of seed motion inside the rolling drum of the planter was established and a horizontal displaccment formula of the seed was sriven out. The seed dropping angle (critical angle) and the location of the seed reception funnel inside the rolling drum or the seed dibbling hoe on the rolling drum might be determined.
