Abstract

The pneumatic conveying metering technology is used to enhance the filling and clearing capacity of the seed metering device by forming a rotary air flow field inside the airflow distribution. The simulation test results show that the increase of the number of fan blades, the velocity of flow field at different outlets of the seed cleaning area decreases linearly, but the average velocity basically remains unchanged. The flow field velocity in the seed filling area decreased significantly with the increase of fan angle, and the difference between seed filling area and clearing area remains unchanged. When the blade angles in the filling area are the same, the fan blades size has no effect in flow field velocity.
