摘　　要：简述了解决气力轮式排种器技术关键的途径。对型孔轮式排种器及其带充填轮和加设气力充填三种情况进行了对比试验分析,从种子尺寸出发正确设计型孔参数,试验分析了投种点位置、型孔参数及壳体材料(及其表面粗糙度)对投种精度的影响。这些对常见型孔式和气力式排种器设计研究有参考价值。The methods to solve the key technical problems of pneumatic wheel-type seed-metering derice have briefly been introduced. Test results of three cases which are cell wheel-type seed-metering device alone, the same with filling roller added and that with air pressure filling, are compared and analysed. Cell parameters are properly chosen according to seed sizes. The seed dropping position, the number of cells and the effect of casing material and surface rating on seed dropping accuracy are tested and analysed. That is valuable for design and research of cell wheel-type and pneumatic seed-metering devices.
