Design and Research of Multi-line Metering Device with Ring Groove Push Movement
摘要
Abstract
A multi-line metering device was designed for hill-drop of rice with ring groove push movement .Working principle of the multi-line metering device and force on dropping seed were analyzed , improvement design of structure for cleaning and protecting seeds were made , and the theoretical maximum speed of the metering plate was investigated by theoretical calculation of precision sowing condition .On the base of agronomic requirement for hole distance , a hole space adjustable mechanism was designed.It' s change gears engagement to obtain different transmission ratio and rea lized the sowing distance adjustable under the certain range .Kinematics simulation analysis for the hole space adjusta-ble mechanism was made on the base of Pro/E, the results showed that the transmission ratio can meet the theoretical re-quest , the adjustable range of hole distance is rational and device working stable and performance well .关键词
