Optimization and Experiment of Cleaning Device of Semi-feeding Peanut Combine Harvester Based on EDEM
摘要
Abstract
In order to solve the problems of high impurity rate and loss rate of semi-feeding peanut combine harvester in clay soil environment,based on the comprehensive analysis of the whole structure of peanut harvester,a cleaning device was designed,combined with the actual harvest situation and peanut physical characteristics,the structure and size pa-rameters of the key components were optimized.Through theoretical analysis,the motion model of sieve body and material was established,and the main factors affecting the screening effect were vibration frequency,vibration amplitude and screen surface inclination angle.The discrete element model of cleaning device and material was established,the quadratic regression orthogonal combination simulation experiment of three factors and three levels was carried out.The re-sponse surface regression model of impurity rate and loss rate was established,and the multi-objective comprehensive optimization of each factor was carried out.The results showed that the inclination angle of sieve surface was 4°,vibration amplitude was 9.7 mm and vibration frequency was 10.8 Hz.The working parameters were set based on the EDEM simu-lation test data,and the field experiments in clay soil environment were carried out.The optimized cleaning device opera-tion results showed that the impurity content was 2.91%and the loss rate was 1.40%.The results met the operation re-quirements of semi-feeding peanut combine harvester,and the operation effect was excellent in clay environment,which could provide reference for the research and optimization of cleaning device of semi-feeding peanut combine harvester.关键词
