| Abstract: |
| 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. |
