| Abstract: |
| To solve the problem of unreliable performance of the film unwinding device in the film recovery machine for the plow layer, a device for loosening the film by reversing the roller and forcibly unwinding the film from the unwinding roller was designed. The film unwinding device mainly consists of a forward and reverse mechanism and an unwinding roller, effectively achieving the film unwinding function. Analysis and parameter calculations were conducted for key working components, and effect of film unwinding conditions were determined. The experiment set the unwinding roller speed set at 167.86 r·min-1 and the roller reversal speed at 43 r·min-1. Using the forward speed of the implement, the unwinding roller speed, and the roller reversal speed as experimental factors, and using the film unwinding rate and the soil content in the recovered mixture as evaluation indicators, a three\|factor, three\|level orthogonal experiment was used. The experimental results were analyzed using Design\|Expert 13.0 software to obtain the interaction effects between each factor and the evaluation indicators. It was found that the factors affecting the film unwinding rate (in decreasing order of impact) were the roller reversal speed, the unwinding roller speed, and the implement’s forward speed. For the soil content in the recovered mixture, the influencing factors (in decreasing order of impact) were the unwinding roller speed, the implement’s forward speed, and the roller reversal speed. By optimizing the regression model, the most suitable parameter combination for the operation of the film unwinding device was determined to be an implement forward speed of 4.37 km·h-1, a roller reversal speed of 184.70 r·min-1, and an unwinding roller speed of 61.95 r·min-1. Field tests were conducted using this optimal parameter combination. The results demonstrated that the film unwinding rate of the device was 73.21%, and the soil content in the recovered mixture was 16.20%. The relative errors compared to the theoretically optimized values did not exceed 1%, meeting the design requirements. |
