EXPERIMENT AND PARAMETERS OPTIMIZATION OF SEED DISTRIBUTOR OF MECHANICAL WHEAT SHOOTING SEED-METERING DEVICE

In order to solve problems of lower seed-filling stability and wheat seed damage mechanical shooting seed-metering device, the filling structure device was optimized. The effects movement were obtained through analysing kinematics dynamics distributor. influence factors inner diameter distributor, rotational speed distributor inclination angle window. discrete element software (DEM) used simulate motion process explore different on seeds’ characteristics in device. coefficient variation uniformity selected as test indicators. A verification experiment conducted, a high-speed camera taken obtain seed’s speed. showed that constant uniform amount average depth 8.6% 32 mm, respectively.
