This article explores challenges in soybean plot breeding, focusing on seed cleaning/replacement and variety adaptability, introducing an innovative seeder using an alternating cleaning-seeding principle. Composed of a main frame, handle, and electric sliding seed metering device, it features two independent brush wheel seeders on one slide for seamless sowing-cleaning transitions. Equipped with 5 variable-sized seed plates, it addresses variety adaptability, while a seed cleaning knife and guiding groove eliminate empty placements. Structural analysis sets parameters: seed box lower limit angle (135°), brush angle (45°), seed plate diameter (130mm), and 26 cells. EDEM simulations verified residue-free variety switching via metering zone dynamics. A 3D-printed prototype underwent bench/field tests: bench tests showed row spacing adjustment capability (needing speed coordination refinement), while field tests confirmed residue-free seeding, simple cleaning, and high quality (90.1% row spacing qualification, 4.5% reseeding, 5.4% miss rate). This achievement enhances plot seeding precision, replacement efficiency, and labor reduction, offering critical insights for plot seeder development.
