Abstract:  The reasonable operating parameters of the leaf stripping element of the tensile sugarcane leaf stripping machine can effectively improve the quality of the leaf stripping mechanism. In order to reduce the impurity rate, a simulation model of sugarcane leaf stripping process was established. The single factor simulation test was used to analyze the influence of the rotation speed of the leaf stripping roller, the leaf stripping angle and the center distance of the leaf stripping roller (the staggered depth of the leaf stripping element) on the peak stress of the sugarcane leaf and the peeling fracture of the sugarcane leaf, and the parameter range was determined. On the basis of simulation analysis, through the prototype test of sugarcane leaf stripping, the central combination method was used to explore the influence of three operating parameters on the impurity rate and the optimal operating parameters were obtained, including leaf stripping angle 120°, leaf stripping roller center distance 77.2 mm, leaf stripping roller speed 128 r/min, minimum impurity rate 2.03%. The impurity rate obtained from the prototype test was 2.09%. The results of this study provide a reference for improving the leaf stripping effect and operation adaptability of the pulling sugarcane leaf stripper.
