摘　　要：阐明了玉米秸秆的冲击式茎叶分离原理 ,并建立了茎叶分离效果数学模型 ,优化确定了茎叶分离的最佳条件 ,分析了各参数对分离效果的影响规律。试验得出了玉米秸秆茎叶分离的最佳分离条件 :冲击头线速度为2 6 .76 m / s,茎叶含水率为 31.5 1% ,喂入速度为 0 .14 m / s。The principle of the shocked separation of stalks and leaves of cornstalk was described and the mathematical models used for evaluating the separation efficiency were established based on the experimental results. The optimum operating condition and the effects of parameters on separation results were analyzed by using the models. The analyzing results showed that the optimum operating condition was 26 76 m/s of shockpiece velocity, 31 51% of cornstalk moisture content and 0 14 m/s of feed rate.
