固定式打孔播种机工作过程的理论分析与计算机仿真

Theoretic Analysis and Computer Simulation of a New Spade Punch Planter Working Process

提出一种结构新颖的打孔式播种机——固定式打孔播种机，对这种播种机的工作过程进行了理论分析和计算机仿真，为这种播种机的设计和使用奠定了理论基础。

In this paper, a new spade punch planter is provided and working process of the planter is theoretically analyzed. Based on these, the mathematic models of punching and dropping and the curve equations of the hole are presented. Working process of the planter is simulated on computer by the models. The results in this paper lay the foundation for designing and using of the planter.
