In view of the problems of a poor seed-filling state and poor seed-cleaning effect of a
precision metering device under high-speed working conditions, an inside-filling air-assisted …

This study proposed a pneumatic type of high-speed maize precision seed metering device
and analysed the motion mechanism of maize seeds during the filling, cleaning, and seed …

Vacuum-type pneumatic metering device has gradually replaced traditional mechanical
seeder and been widely used for corn precision planter in China because of its low damage …

A high-speed seed-metering device was designed utilising centrifugal force for seed filling
and clearing and air movement to achieve efficient and stable single seed filling. To avoid …

Combined with the good filling performance of the inside-filling seed metering device, in this
study, one kind of combined nozzles was designed using the principle of gas cleaning of air …

In this paper, a centrifugal filling and cleaning high-speed precision seed metering device
for maize is designed based on the principle of centrifugal force generated by high-speed …

This study introduced a high-speed precision dual-chamber maize seed metering device
and examined the impact of irregular-shaped holes on the planting quality in order to …

This work aimed to improve the seeding quality of maize and to investigate the influence of
the seed drop tube on the seeding quality. The airflow-assisted seed-dropping device (the …
