摘　　要：搅拌装置是棉秸秆发酵饲料设备的重要组成部分,文章通过基于对搅拌装置的结构和工作原理的分析,对搅拌轴、搅拌支杆、螺带式叶片进行设计。通过Solidworks软件对搅拌装置建立模型,利用ANSYS软件对发酵设备的搅拌装置进行有限元分析,得到静态和工作状态下的总变形云图和等效应力云图。结果表明:搅拌轴空转与工作过程中最大变形分别为2.079 9×10^(-6)mm和127 740×10^(-6)mm,最大等效应力分别为1 045.5 Pa和5.180 8×10^(7)Pa,强度符合使用要求。经样机试验验证,发酵设备作业后的饲料发酵时间比自然发酵作业少10 d,物料含水率偏差≤±1.0%,物料发酵温度偏差≤±1.5℃。The structure and working principle of the agitator were analyzed,and the agitator shaft,the agitator branch and the screw-belt blade were designed in this paper.The agitator was modeled by Solid⁃Works software,and analyzed by ANSYS software,and the total deformation and equivalent stress nepho⁃grams under static and working conditions were obtained.The results showed that the maximum deforma⁃tion are 2.0799×10^(-6) mm and 127740×10^(-6) mm respectively,and the maximum equivalent stress is 1045.5 Pa and 5.1808×10^(7) Pa respectively,which provides theoretical support for the design of fermen⁃tation equipment for cotton straw feed.The experimental results of the prototype indicated that the fer⁃mentation time of the feed was 10 days less than that of the natural fermentation,and the deviation of the moisture content and the fermentation temperature of the feed were≤±1.0%and±1.5℃.
