    摘要:

    為降低撿拾脫粒機撿拾損失，采用響應(yīng)面分析方法對撿拾部件的參數(shù)進行試驗。試驗結(jié)果和分析表明：影響撿拾損失的重要因素是機組前進速度、輸送帶速和輸送傾角；3個影響因素按重要性排序為：機組作業(yè)速度、輸送帶速、輸送傾角。確定了一組最優(yōu)的參數(shù)組合：機組前進速度0.80m/s，輸送帶速0.78m/s，輸送傾角11.19°，優(yōu)化后撿拾損失率的理論值為2.91%?？紤]實際機械作業(yè)過程中的參數(shù)調(diào)整問題，推薦參數(shù)組合為：機組前進速度0.71m/s，輸送帶速0.80m/s，輸送傾角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°.
