摘　　要：为提高我国的种子玉米脱粒质量,提出复式双滚筒玉米脱粒装置的总体设计思路和关键结构的设计方案。通过脱粒装置参数优化试验,得出各参数的最优组合。试验证明,影响综合指标的因素主次顺序为主滚筒转速>纹杆螺旋角度>副滚筒转速。This paper expounds on the general structure of the double roller corn threshing device and the working principle of threshing device. The optimal combination of various parameters is obtained through optimization experiment on the parameters of the threshing device. The experiment shows that the primary sequence of the influence factors on the comprehensive index is as follows：Master drum speed 〉Threaded rod spiral angle 〉 vice roller speed, and in the optimal combination level, the damage rate of the device is 0.35%, no clean rate is 0.62%.
