摘　　要：为了减小绞龙轴的磨损深度,提高洗麦机工作性能,以绞龙轴的叶片直径、叶片螺距、轴径、转速为影响因素,运用单因素试验、正交试验、响应面优化试验相结合的方法,分析各因素对研究目标的影响情况并进行参数优化。结果表明,绞龙轴的磨损随叶片直径、叶片螺距、轴径、转速的增大而增大,影响因素的权重:转速>叶片直径>叶片螺距>轴径;绞龙轴的输送效率随叶片直径、叶片螺距、轴径、转速的增大而增大,影响因素的权重:转速>叶片直径>轴径>叶片螺距。绞龙轴最佳参数组合:绞龙轴叶片直径195 mm,叶片螺距105 mm,轴径75 mm,转速250 r/min。研究结果可为洗麦机设备的设计研究及优化提供借鉴。In order to improve the working performance of the wheat washer,the influence of each factor on the research objectives was analyzed and the parameters were optimized by taking the blade diameter,pitch,shaft diameter and rotation speed as the influencing factors,and improving the working efficiency of the auger shaft and reducing the maximum wear of the auger shaft.The results show that the wear of the auger shaft increases with the increase of blade diameter,pitch,shaft diameter and speed,and the weights of the influencing factors are ranked as follows:speed>blade diameter>pitch>shaft diameter.Addtionally,the conveying efficiency of the auger shaft increases with the increase of blade diameter,pitch,shaft diameter and speed,and the weights of the influencing factors are ranked as speed>blade diameter>shaft diameter>pitch.The optimal parameter combination for tauger shaft is:auger shaft blade diameter 195 mm,auger shaft pitch 105 mm,auger shaft diameter 75 mm,auger shaft speed 250 r/min.The above research results can provide some reference for the research and equipment optimization of wheat washer.
