We designed a mechanical horizontal disc radish seeder. To verify the reliability of the seed discharger, we analyzed and optimized the rotational speed, thickness and rounded hole size of the seeding disc by discrete element software, and through the experimental simulation, we successfully achieved the effects of uniform seed discharge, low seed jamming rate, and reduction of the leakage phenomenon, with the qualified index of grain spacing S = 85.21%, the index of replanting D = 13.73%, and the index of leakage M = 1.05%.
