Since The Material Analysis And Optimization Of Key Parts Of Cotton Picker

Cotton is our country especially Xinjiang important economic crops, in themechanization of cotton production process mechanization harvest cotton has becomean inevitable trend.Hand picking don’t only high labor intensity, low efficiency, andhigh cost. Therefore, it is necessary to design a machine can replace manual pickingcotton, to reduce the heavy manual labor, improve work efficiency, adapt to therequirements of social development of agricultural mechanization. Xinjiang areabegan to introduce foreign large-scale self-propelled cotton picker, some domesticmanufacturers also began to introduce foreign advanced technology and independentresearch and development of color cotton machine. At present, the domestic marketmainstream products are mainly collected cotton American Deere Company, KeyesCo and Guihang Group production of horizontal spindle type cotton picker. Domesticcotton picker is the performance can meet the requirements, but with the Americathere is still a certain gap, the key parts especially cotton picker spindle is stilldependent on imports, fully realize the localization is still a long way to go. Thecotton picker is gradually applied in the actual production, mechanization of cottonharvesting and greatly reduces the cost of cotton, reducing the labor intensity,improve the enthusiasm of face.Picking head is the core component of cotton picker picking head, at present inXinjiang area of cotton picker for horizontal spindle rolling, the domestic productionof the cotton picking head parts are from abroad to buy, no domestic independentproduction enterprises. So, on the material analysis and optimization of theself-propelled cotton picker level ingots study a cotton picker localization is verynecessary, has the important meaning.In this paper, according to key parts of the self-propelled cotton pickerespecially the level of abstract principle of ingot and the material analysis. Create a cotton picking head spindle, seat tube, elbow and other key parts solid model andrealize the simulation model by UG software installation and combination function of3D graphics, drawing the design drawings.In this paper, the finite element analysis software ANSYS_static structuralanalysis, to calculate the maximum of stress and strain of spindle of cotton picker;after checking, the maximum value in the allowable range.Aiming at the domestic self-propelled cotton picker spindle hook parts platinglayer and the substrate layer combined form and its thickness, inclusion, crackelement classification analyze optimization solution. Using the method of selfwalking type cotton picker picking head key parts for research, design optimization ofhorizontal cylinder ingots and colored cotton and preparation of relevant parts andtooling design calculation manual, lay a good foundation for further improvement ofcotton head localization.The results of this study on the self walking optimization type domestic cottonpicker spindle function has the guiding role, for the development of AgriculturalMechanization in China, has important significance for improving the quality ofdomestic cotton picker.
