摘　　要：在水平螺旋输送试验装置上对切碎玉米秸秆的螺旋输送性能进行了单因素试验和正交试验,研究了螺旋轴转速、填充系数和螺距对输送量和功率消耗的影响。单因素试验结果表明:螺旋轴转速、填充系数和螺距对输送量和功率消耗的影响显著;且随着螺旋轴转速、填充系数和螺距的增大,输送量和功率消耗都呈上升趋势。正交试验结果表明:因素对输送量影响的主次顺序是螺距、填充系数、转速;因素对功率消耗影响的主次顺序是转速、螺距、填充系数。采用综合平衡法最终得到的较优水平组合是A1B1C3,即螺旋轴转速56r/min、填充系数0.3、螺距3 0 0 mm。本试验可为提高玉米秸秆螺旋输送综合质量提供参考。This paper studied the single factor test and the orthogonal test of the screw conveyor performance of chopped corn stalks in the horizontal screw conveyor test device .The experiment studied the influence to the productivity and power consumption on the screw shaft speed , filling coefficient and pitch .The single factor test showed that the screw shaft speed , filling coefficient and pitch influenced the productivity and power consumption significantly ;and with the in-crease of screw shaft speed , the increase of filling coefficient and the increase of pitch , the productivity and power con-sumption are on the rise .The orthogonal test showed that these three factors impact on the productivity of the primary and secondary order is pitch , filling coefficient , screw shaft speed;these three factors impact on the power consumption of the primary and secondary order is screw shaft speed;pitch , filling coefficient .By the integrated balance method , the opti-mal level combination to maximize the productivity is A 1 B1 C3 , namely screw shaft speed 56 r/min, filling coefficient of 0.3, the pitch of 300 mm.This experiment can provide reference to improve the overall quality of the corn stalks spiral conveying .
