Abstract

This research aims to optimize the working parameters of the sawtooth-type recovery device for cotton fallen on the ground to enhance cotton’s recovery effect. Firstly, the cotton-picking mechanism and cotton unloading mechanism of the cotton recovery device were designed. The movement trajectory of the serrated tooth end of the designed device, the cotton non-missing picking condition, and the cotton unloading condition were noted. Secondly, virtual simulation technology developed a model of the interaction process between the picking equipment and the soil. To determine the optimal combination of operating parameters for the recovery device, a three-factor, three-level response surface optimization test was conducted using Box–Behnken’s central combination method with operating machine speed, spacing between serrated discs, and serrated disc speed as the test factors, and the picking and impurity rate as the test indexes. In addition, a response surface regression model was developed to analyze the effects of the selected factors on the recovery unit, and each factor was optimized. When the picking and impurity rates were 79.09% and 35.12%, respectively, the optimal operating speed of the machine was 0.96 m/s, the spacing of the serrated discs was 40 mm, and the speed of the serrated discs was 68 rpm. The relative error between the experimental findings and the theoretical optimized values was less than 5%, and the optimized working parameters were reliable. This study can provide a reference for the device used to recover cotton that has fallen to the ground.
