摘要:

为降低捡拾脱粒机捡拾损失，采用响应面分析方法对捡拾部件的参数进行试验。试验结果和分析表明：影响捡拾损失的重要因素是机组前进速度、输送带速和输送倾角；3个影响因素按重要性排序为：机组作业速度、输送带速、输送倾角。确定了一组最优的参数组合：机组前进速度0.80m/s，输送带速0.78m/s，输送倾角11.19°，优化后捡拾损失率的理论值为2.91%。考虑实际机械作业过程中的参数调整问题，推荐参数组合为：机组前进速度0.71m/s，输送带速0.80m/s，输送倾角12°。

Abstract:

In order to reduce the loss rate in picking up, parameters of pickup device with response surface analysis methods was studied. The results showed that main factors of impacting pickup loss rate were the moving speed, belt speed and conveyor inclination. The three factors gradation of importance was the moving speed, belt speed and conveyor inclination. Optimal group of parameters was the moving speed of 0.80m/s, the belt speed of 0.78m/s，the conveyor inclination of 11.19°, the optimal loss rate of 2.91%. Considering of parameters adjusting in actual conditions, recommended parameters were that the moving speed of 0.71m/s, the belt speed of 0.80m/s, the conveyor inclination of 12°.
