“…The seed-metering device is a key component in this technology (Singh et al, 2020;Inderpal et al, 2020;Singh et al, 2021). Their efficiency and reliability play a decisive role in sowing quality and ensuring that agronomic production is carried out properly (Balappa et al, 2021;Zhang et al, 2021a). Currently, there are two main types of maize seed-metering devices: pneumatic and mechanical (Liao et al, 2020).…”

To solve the current problems of poor seeding stability and complex maintenance of maize seed-metering devices, a clamp-holding precision maize-seed-metering device is designed. The structure and working principle of the seed-metering device are described, the optimum state of maize seed clamping is analyzed, and the range of each working area of the seed-metering device is determined. The profile and structural parameters of the limit guide plate are designed by analyzing the laws of motion of the seed-picking block. A mechanical model of maize seeds under the critical state in each working area of the seed-metering device is established. The influence of the seed-metering device's rotational speed and the clamping force of the seed-picking block on the seeding performance are analyzed. A physical prototype of the seed-metering device was made for bench tests and field verification tests. The qualified, multiple seeding, and missed seeding rates of the designed seed-metering device were 94.21%, 3.52%, and 2.27%, respectively, meeting the agronomic requirements of maize sowing. The study provides theoretical guidance for designing and optimizing precision maize-seed-metering devices.
