Optimization of the Adjustable Screw Dosing Parameters of a Grain Seeder Designed for Agricultural Dryland

This study focuses on optimizing the parameters of a screw dosing system in grain seeders for dryland agriculture to improve seed sowing efficiency. While ensuring agronomic requirements for seed distribution remains a challenge, the study addresses this gap by conducting multi-factor experiments using the Hartley-3 design. The research examines the effects of funnel surface area, screw rotation speed, and aggregate movement speed on sowing performance. Results indicate that these factors significantly influence sowing rates and seed distribution. Optimal settings for screw rotation and funnel area were identified, which promote uniform seed distribution. These findings have important implications for enhancing agricultural efficiency in dryland farming.
