摘　　要：为实现甘蔗种植机的供种系统与播种系统的联调工作,设计了一种倒三角状的集蔗箱并优化其参数,使蔗种从供种系统到播种系统过程中不乱序、不卡蔗、不堵塞。通过对蔗种在集蔗箱中的运动分析和EDEM运动仿真,探究了蔗种的运动机理和影响蔗种落种有序的因素。通过单因素试验和正交试验,研究了落种高度、导蔗板倾斜角和集蔗量对蔗种有序率和充种率的影响,结果表明:落种高度和集蔗量对落种有序率有着极显著影响,导蔗板倾角对落种有序率有着显著影响;对蔗种充种率,落种高度有着极显著影响,集蔗量影响显著,导蔗板倾斜角影响不显著。综合考虑后,最佳因素组合为:落种高度为200mm,导蔗板倾斜角为45°,集蔗量为25根。In order to realize the joint work of seed supply and seeding system of sugarcane planting machine,an inverted triangular-shaped seed collection box was designed and its parameters were optimized so that the seeds would not be disordered,stuck or blocked during the process from seed supply system to seed system.By analyzing the movement of seeds in the seed collection box and EDEM motion simulation,the movement mechanism of seeds and the factors affecting the order of seed drop were investigated.Through the single-factor experiments and orthogonal experiments in the workshop,the effects of seed drop height,tilt angle of seed guide plate and seed collection volume on seed orderly rate and seed filling rate were studied.The results of the platform experiments show that seed drop height and seed collection volume have extremely significant effects on seed drop orderly rate,and tilt angle of seed guide plate has a significant effect.For the seed filling rate,seed drop height has an extremely significant effect,seed collection volume has a significant effect,and tilt angle of seed guide plate has an insignificant effect.The optimal combination of factors are determined to obtain more optimal the qualification rate based on the orthogonal experiments,that is,the seed drop height is 200mm,the seed plate is tilted at an angle of 45°,and the amount of seed collected is 25.
