| 为提高新疆棉田残膜回收机械化水平，解决机具残膜回收率低、含杂率高等问题，研究设计一种秸秆还田残膜回收一体机。根据新疆棉花的种植模式和田间作业要求对整机的关键零部件进行设计，确定了甩刀型粉碎刀、绞龙转速为1 500 r·min-1、捡膜滚筒回转半径为245 mm、脱模板回转半径为278.5 mm等零部件参数。选取机具行进速度、捡膜齿入土深度、输出轴转速为影响因素，以残膜回收率、含杂率为试验指标，设计三因素三水平正交试验并进行测试，确定了最优参数组合：机具前进速度7 km·h-1、捡膜齿入土深度25 mm，输出轴转速760 r·min-1。根据最优参数进行试验验证，结果表明：在最优参数组合下，残膜回收率的均值为85.03%，含杂率的均值为15.88%，其与理论值对比误差均小于3%，模型可靠。该研究成果可以满足残膜回收机田间作业要求。 |

| To improve the mechanization level of film residue recovery in cotton field in Xinjiang and solve the problems of low film residue recovery rate and high impurity rate of machine tools, this study designed an integrated machine for film residue recovery and straw returning to field. According to the planting mode and field operation requirements of Xinjiang cotton, the key parts of the whole machine were redesigned. The parameters of the spinner type crushing knife and the skein speed was 1 500 r·min-1. The rotary radius of the film picking drum was 245 mm, and the rotary radius of the template stripping was 278.5 mm. The moving speed of the machine tool, the depth of the pick\|up film teeth in the soil and the rotation speed of the output shaft were selected as the influencing factors, and the recovery rate of the remnant film and the impurity content rate were taken as the test indexes. The design\|expert 8.0.6.1 software was used to carry out three\|factor three\|level orthogonal experiment design. The optimum parameters were determined as follows: the forward speed of the machine tool was 7 km·h-1, the depth of the collecting film teeth into the soil was 25 mm, and the rotation speed of the output shaft was 760 r·min-1. The experimental results showed that under the optimal parameters, the average recovery of residual film was 85.03%, the average impurity content was 15.88%, and the comparison error with theoretical value was less than 3%. The model was reliable. The research results met the requirements of the field operation of the residual film recovery machine. |
