摘　　要：针对机械式播种种箱机种群起拱,以及新疆宽幅作业播种机整机结构复杂臃肿、振动大、动力消耗大等问题,提出了基于有序供种条件下机械式精量取种的方案,设计了一种基于有序充种的集排滚筒式排种器。同时,阐述了有序充种工作原理,以棉花种子为试验对象,以供种倾角、滚筒转速、窝孔开口大小为影响因子,以单粒率、多粒率、漏播率为排种性能指标,选择二次旋转正交组合试验,分析各影响因子对排种性能的显著性与规律。试验结果表明:供种倾角为38°、滚筒转速为8r/min、窝孔开口为13mm时,性能指标达到最佳,单粒率为91.5%,多粒率为4.66%,漏播率为2.4%,满足棉花精量播种要求。Aiming at the problem of arching of the mechanical seeder box machine, the complex structure of the Xinjiang wide-operation seeder, bloated structure, large vibration, and large power consumption, a mechanical precision seeding scheme based on ordered seeding conditions was proposed. A sorting and collecting drum seeder based on orderly seeding is provided.The working principle of orderly seeding was elaborated, cotton seeds were used as test objects, the inclination angle of seed supply, the rotation speed of the drum, and the size of the hole openings were taken as the influencing factors. Carry out the second rotation orthogonal combination test, analyze the significance of each influencing factor on seeding performance Sex and regularity. the best parameter combination is obtained: the inclination angle of the seed is 38°, the rotation speed of the drum is 8 r/min, and the hole opening is 13 mm. 4.66%, the missed sowing rate was 2.4%;after the experimental verification, which met the requirements of cotton precision seeding.
