| 针对残膜机械化回收过程中残膜回收率低、回收的残膜成捆质量差、膜捆遍地卸及作业油耗高等问题，设计了一种残膜回收打捆与秸秆粉碎联合作业机。介绍了残膜回收打捆与秸秆粉碎联合作业机的结构组成及工作过程，重点对残膜捡拾装置、打捆装置进行设计，并对残膜捡拾、打捆作业过程进行运动学和动力学分析。为验证残膜回收打捆与秸秆粉碎联合作业机作业性能，进行了以收膜链耙转速、机具前进速度、收膜弹齿入土深度为试验因素，以残膜捡拾率、残膜含杂率、机具耗油量为响应值的田间试验，建立回归模型，并进行参数优化与试验验证。试验结果表明：影响残膜捡拾率的因素由强到弱依次为机具行驶速度、收膜链耙转速、弹齿入土深度；影响残膜含杂率的因素由强到弱依次为机具行驶速度、弹齿入土深度、收膜链耙转速；影响机具耗油量的因素由强到弱依次为机具行驶速度、弹齿入土深度、收膜链耙转速。理论最优的作业参数为链耙转速119.06 r·min-1、机组前进速度6.319 km·h-1、弹齿入土深度63.29 mm。田间验证试验表明：在圆整后的最佳工作参数条件下，残膜捡拾率均值为93.88%、残膜含杂率均值为79.76%、机具油耗量均值为14.85 L·hm-2。 |

| A combined machine for residual film recycling, bundling, boxing, and straw crushing was designed to address the issues of low residual film recovery rate, poor bundling quality, widespread unloading of film bundles, and high fuel consumption during the mechanized recycling process. This study introduced the structural composition and working process of a combined machine for residual film recycling, bundling, and straw crushing, with a focus on optimizing the design of the plastic film picking device, bundling device, and straw crushing device. Through kinematic and dynamic analysis of the process of picking and bundling plastic film, the structural and working parameters of each functional component were determined. To verify the operational performance and fuel consumption of the combined machine for residual film recycling, bundling, and straw crushing, a three factor three\|level quadratic regression experiment was conducted with the speed of the film harvesting chain rake, the forward speed of the machine, and the depth of the film harvesting bullet teeth entering the soil as experimental factors. The response values were film picking rate, film impurity rate, and unit fuel consumption. A regression model was established to examine the effects of each factor on film picking rate, film impurity rate, and unit fuel consumption, and parameter optimization and experimental verification were carried out. The experimental results showed that the factors affecting the recovery rate of plastic film, from large to small, were as follows: machine driving speed>film harvesting chain rake speed>depth of tooth penetration into the soil. The factors influencing the impurity content of plastic film were ranked as follows: machine driving speed > depth of tooth penetration into the soil > speed of the film harvesting chain rake. Similarly, the factors affecting the implement’s fuel consumption are ranked as follows: travel speed of the implement > depth of tooth penetration into the soil > speed of the film harvesting chain rake.The theoretically optimal operating parameters include a chain rake speed of 119.06 r·min-1, a unit forward speed of 6.319 km·h-1, a tooth penetration depth of 63.29 mm. Field validation experiments demonstrated that under the optimal working parameters (rounded values), the average plastic film recovery rate was 93.88%, the average impurity content of recycled plastic film was 79.76%, and the average of implement’s oil consumption was 14.85 L·hm-2. |
