1双齿轮式排肥器设计与试验显示文摘为了提高颗粒肥料的施肥均匀性,设计了双齿轮式排肥器。利用离散元软件对排肥过程进行仿真分析,以排肥轮压力角、排肥轮间隙为试验因素,以排肥均匀度变异系数为排肥效果评价指标,分析因素对指标的影响。单因素试验结果表明,排肥轮压力角在15°~25°,排肥轮间隙在4~6 mm,排肥效果较好;通过二次通用旋转组合试验,建立了两个因素与评价指标的回归方程,试验结果表明,随排肥轮压力角、排肥轮间隙的增大,排肥均匀度变异系数均呈现先增大、后减小的趋势,当排肥轮压力角为19.52°、排肥轮间隙为4.7 mm时,排肥器具有最优的排肥效果,此时理论计算和仿真试验的排肥均匀度变异系数分别为15.30%和14.58%,两者偏差为0.72个百分点,说明回归模型准确。最优结构参数组合下双齿轮式排肥器的台架试验结果表明,排肥量可通过排肥轮转速线性调节,排肥均匀度变异系数为15.42%,与仿真值及理论值基本一致;同等条件下外槽轮排肥器的排肥均匀度变异系数为20.29%,试验排肥器排肥均匀度变异系数提高了31.58%,排肥均匀性得到明显改善。顿国强 于春玲 郭艳玲 纪文义 ISLAM K R 杜佳兴 2020农业机械学报2020,51,3:17
