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

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.
