| Abstract: | On the basis of analyzing the construction characteristics and the working process of a revolving spade soil opener a mathematical model was established to describe spade moving trace. The working principle and the influences of construction parameters of the soil opener on the length and the width of soil hole formed by spade on the soil surface were analyzed. The results show that the length of the soil hole increases with the increment of the horizontal and vertical angles of the declined spade soil opener and the width of the soil hole increases with the increment of the horizontal angle. |
