摘  要:
Based on working principle of a horizontal plate precision metering device, the causes of seed damaging and delivery precision of the existing pusher and ejector were analyzed and a new type of ball bearing pusher and ejector was developed. The results from both field and laboratory experiments show that the ball bearing pusher and ejector improves metering performance and reduces seed damage.
