To solve existing problems of tobacco manual transplanting such as high labor intensity,poor in-dependence of mechanized equipment and low reliability,design of transplantation-cavitation mechanism for self-propelled tobacco transplanter was optimized.ADAMS was used to simulate and analyze the trans-plantation-cavitation mechanism,and EDEM was applied to construct the simulation model of threaded burrower.Through orthogonal combination tests,significance among threaded burrower indices was ana-lyzed,and the best parameter combination was concluded as the threaded burrower diameter of 160 mm,thread number of 3,and rotation speed of 1 800 r/min.The field experiments were carried out and the rate of injury seedlings was 0.33％,the rate of qualified plant spacing was 85.67％,and the rate of leakage of transplanting was 1.33％.Transplanting holes could be watered simultaneously,and the continuous bur-rowing transplanting was realized,which could meet the agronomic requirements of modern tobacco trans-planting.
