Improved Design and Experimental Research on Seed Supply Device of Pre-cut Sugarcane Transverse Planter

To realize the stable and orderly seeding of sugarcane, the seeding device of the existing pre-cut sugarcane horizontal planting machine is improved. This paper analyzes the movement of sugarcane seeds in the process of seed supply and explores the movement mechanism of the seed supply. Adams was used to analyzing the process of sugarcane seed supply by simulation, which verified the feasibility of the improved seed supply device. The single factor experiment and orthogonal experiment were carried out to study the effects of four factors including seed number, drop height, offset distance and opening size on seeding effect, and the factors affecting the seeding quality were found out. Experiments show that the offset distance and opening size have a significant effect on the order rate and the pass rate, and the optimal parameter combination is A1 B3(the offset distance is 90 mm, the opening size is 180°).
