Comb-type Cotton Picker Seed Cotton Cleaning Device Theoretical And Experimental Study

Xinjiang, as the largest commodity cotton base and export high-quality cotton base, cotton yields, total production and quality has always been among the best in the country. However, due to the cotton-growing area, harvest is relatively concentrated. Pick cotton difficulty become an obstacle to the development of cotton industry in Xinjiang and the Corps, become the prominent contradictions. Cotton picker is a achieve full mechanization of cotton production in the key equipment, due to short of this equipment. It has restricted the development of Xinjiang cotton industry. Over the years, the core of Cotton Picker manufacturing technology is monopolized by a few countries, but only has single tablet models of picking cotton, mechanized harvesting of cotton and the popularization of technology has created a significant barrier. This article through research comb-type cotton picker machine of cleaning equipment to optimize its performance and improve the stability of comb-type cotton picker, Add a new model for cotton harvesting machine, ease the labor shortage in the cotton harvest season.The main contents are as follows:Briefly analysis the Comb-type cotton picker device structure and operating principle, introduces the main characteristics of the device. Focused on the principle of barbed nails roller, serrated roller, brush clean cotton flower roller, to determine its quantity, diameter and other parameters.In comb-type cotton picker of seed cotton cleaning device cleaning parameter optimization experiment, through the seed cotton cleaning device's main performance parameters and motion parameters-barbed nails roller speed, serrated roller speed, brush clean cotton flower roller speed experiment, mainly studies the device of different parameters with clear relationship between the seed cotton cleaning effect obtained indicators of primary and secondary factors and the significance of each factor level.Through a large number of performance tests and results analysis, the comb-type cotton picker of seed cotton cleaning device, the main performance parameters and motion parameters-barbed nails drum speed, serrated roller speed, brush speed and clean cotton roll between the device performance regression model, and analyzes the performance of various factors on the degree of influence complex clearance.Application the Matlab optimization toolbox that the mathematical model of multi-objective optimization, the seed cotton cleaning devices is integrated optimization of operating parameters.The results of this study have practical significance for the seed cotton cleaning device's design. At the same time in the future development of the cotton harvesting machinery to provide the theoretical basis and scientific guidance.
