【摘要】 为了深入研究影响弹齿式拾膜机构工作性能的因素,确定弹齿式拾膜机构的最佳工作条件,对该机构运动进行了理论分析和仿真分析。利用土槽台架试验系统对影响机构拾膜率的机具行进速度、速比(弹齿轴与机具行进速度的比值)、托膜铲入土深度3个主要因素进行了正交试验,结果表明,理论分析及运动仿真与台架试验结果一致,速比的变化对机构拾膜率的影响程度大于机具行进速度和托膜铲入土深度的变化,当机具行进速度为0.7 m/s、速比为1.0、托膜铲入土深度为110 mm时,弹齿式拾膜机构的拾膜率较优。更多还原

【Abstract】 To investigate factors influencing the performance of mulching plastic film collector and determine the optimal working conditions,the theoretical analysis and motion simulation were carried out.By using the soil-bin trolley experiment,the orthogonal experiment with influence factors of machine operating speed,speed ratio( the ratio of spring-tooth axis speed and the speed of machine operating)and the embedded depth of the shovel for lifting film was carried out.Consistent with theoretical analysis,simulative studies demonstrated that the collection ratio of mechanism could reach the optimal when the machine operating speed was 0.7 m/s,the speed ratio was 1.0,and the embedded depth of the shovel for lifting film was 110 mm.更多还原
