中文摘要:
      针对目前残膜回收机具存在的拾净率低和含杂率高等问题，设计了一种垂直双排链式残膜回收机。阐述了整体结构和工作原理，对输送装置的关键结构及参数进行分析，开展了垂直双排链作业过程中输膜和卸膜过程的运动学和动力学研究，通过理论计算确定了主要工作部件的作业参数，获得了影响残膜回收性能的关键因素；以输送链转速、卸膜链转速和输送链转运角为试验因素，以残膜拾净率及含杂率为试验指标进行响应面试验。结果表明：影响残膜回收性能的最佳工作参数为输送链转速86.08 r·min-1、卸膜链转速128.97 r·min-1、输送链转运角91.92°，最优参数组合下残膜拾净率为86.3%，含杂率为36.57%。在最优参数组合下进行田间验证试验，得到最优参数组合下的残膜拾净率为86.7%，含杂率为35.9%，满足行业要求。
英文摘要:
      A vertical double\|row chain residual film recovery machine was designed to address the problems of high contamination rate and poor utilization rate of residual film recovery in the current residual film recovery machine. The structure and working principle of the machine were introduced, and the key structure and parameters of the conveying device were analyzed. The kinematics and dynamics of the conveying and unloading process of the vertical double\|row chain operation were studied. The operating parameters of the main working parts were determined by theoretical calculation, and the key factors affecting the performance of film recovery were obtained. The results showed that the optimum parameters affecting the film recovery performance were 86.08 r·min-1 of conveyor chain speed, 128.97 r·min-1 of unloading chain speed and 91.92° of transfer angle of conveyor chain. The film recovery rate was 86.3% and the trash rate was 36.57% under the optimum combination of parameters. The actual recovery rate of residual film under the optimal combination of parameters was 86.7% and the trash rate was 35.9%, which met the industry requirements.
