    摘要:

    分析了双螺旋机构立姿输送长茎秆作物的机理;利用室内试验台,通过正交试验找出了影响输送效果的显著因素,通过回归试验找出了显著因素的较优参数值:螺旋输送器转速为319r/min,上下螺旋输送器距离575mm, 螺旋输送器叶片顶端相对动刀水平距离10mm,叶片升角30°。进行了该组参数下的验证试验,综合评价指标达到89.8,能够较好地适应玉米秸秆的立姿输送要求。

    Abstract:

    Principle of double helix mechanism was analyzed. Through orthogonal tests, the prominent elements were defined. Though regression tests, the optimization parameters of prominent elements were calculated as below: helix-dragon rotating speed of 319r/min, distance between up and down helix dragons of 575mm,distance between helix top and cutting knife of 10mm, lift angle of helix dragon of 30°. And the transporting index reached to 89.8, which could meet the demand of transporting long-straws.
