## 5 Conclusions  
The step-by-step sugarcane harvesting model is tailored to China's diverse sugarcane cultivation, but there is a significant gap in the research regarding the front-end conveying system of the relevant tension-type sugarcane defoliation equipment, necessitating the design and development of a uniform and efficient conveying device. As a result, this research develops a three-dimensional model of a sorting and conveying device and conducts both simulation and physical prototype testing of the sugarcane sorting and conveying process. The key findings are as follows:  
1. In order to address the issues of step-by-step sugarcane harvesting and stripping equipment's inability to efficiently sort and transport the sugarcane in the pile--which is prone to clogging, necessitates manual sorting, and fails to realize the entire mechanized operation, etc.--a sorting and transporting device comprising a lifting conveyor belt, a cane collecting plate, and a sorting mechanism has been designed. The collision process between the sugarcane and the collecting plate has been examined, and it has been found that the two variables influencing the sorting and transporting are the plate's angle of inclination and the sprocket's rotation speed (sorting speed)
2. Based on the ADAMS simulation, the influence mechanisms of the cane collecting plate inclination angle and sprocket rotational speed on the percentage of sorting three canes is studied. The simulation study shows that the percentage of sorting three canes is significantly impacted by the inclination angle of the cane collector plate, the sprocket wheel's rotational speed, and the interaction between the sprocket wheel's rotational speed and the cane collector plate's inclination angle. After analyzing the interaction effect, it was determined that when the inclination angle of the cane collecting plate was 35\({}^{\circ}\) and the rotating speed of the sprocket wheel was 24 r/min, the sorting three cane percentage attained the ideal value of 87.96%. 3. Based on the simulation's optimal parameters, the sorting and conveying device's physical prototype was tested and analyzed. The average percentage of sorting three sugarcane was 80.56%, which was lower than the simulation's value of 87.96%; the relative error between the simulation and test values for the percentage of sorting three sugarcane was 8.4%, and the average percentage of sorting four sugarcane was 1.11%, which fell within a reasonable error range. These results showed that the sorting and conveying device was feasible and practical, and that it could sort sugarcane and avoid blockages. It demonstrates that this sorting and conveying mechanism can efficiently sort sugarcane while preventing blockages, which is both realistic and useful. This paper concludes a simulation analysis and experimental research on the effects of the sprocket speed of a sorting conveyor device and the inclination angle of the cane collecting plate on the stable conveying and efficient sorting of sugarcane, respectively, based on the pull-type sugarcane defoliation equipment developed by the group. The sorting impact of sugarcane is influenced by various combinations of sprocket rotation speed and raising conveyor belt speed (loading speed). The sensors that measure the sugarcane's quality on the loading platform and modify the loading speed might be used in future studies. Furthermore, the sugarcane was defaulted to the straight stalk state during the research process, and experimental validation was also performed on relatively straight sugarcane. In contrast, there was a deficiency in the theoretical research and experimental analysis of curved sugarcane, which can be examined further. To reduce the amount of computer calculations, this paper substitutes a cylindrical rigid body for the sugarcane model in the simulation of the sugarcane sorting and conveying process, due to the limitations of the author's computer equipment.
