Design And Simulation Analysis Of Peanut Sheller With Vertical Tapered

Peanut is an important oil crops in the world and in China. However, in the presence of peanut shelling during the off the net rate is not high, the rate of serious injury problems, seriously affecting the peanut commodity value and economic benefits, in particular a greater impact on breeding peanuts. Peanut shelling off the net for the low rate of serious damage and other issues, this paper Doctoral Program of Higher Specialized Research Fund Project "Peanuts pick picking Combine Harvester core agencies working principle and key technology" (project number.20122103110009) and the National Natural Science Foundation of China "shelling and damage mechanism peanut sheller machinery and low-loss technology research" (project number:50775151), For Shenyang Agricultural University Institute of peanut peanut breeding needs, peanut shelling machine technology at home and abroad on the basis of a review, to start the test study the mechanical properties of peanut pods from physics to study the vertical cone cell breeding peanut shelling device was key theoretical analysis and design of structural components and parameters, husking and shelling process device simulation analysis, in-depth study of peanut shelling devices provide a frame of reference. The main contents and conclusions are as follows:(1) The existing theory and existing peanut shelling shelling technology to analyze the structure of the device, to provide a theoretical basis and technical reference for the breeding cone stand peanut shelling device design.(2) Peanut and peanut pod varieties typical physical parameters related triaxial size and grain weight measurement and statistical analysis to determine the agricultural flower, flower mound, Huayu three varieties of peanut and peanut pod basic dimensions to afford pod triaxial size ratio and nuts substantially normal distribution.(3) Typical varieties of peanuts and peanut pod physical and mechanical properties were studied. By Peanut physical and mechanical properties test typical varieties analyzed obtained elastic modulus and peanut elastic modulus peanut pod and peanut shell breaking force and breakage force at different moisture content, as well as under different moisture content of peanut pods; through the peanut pods under different loading directions of stress analysis to study the broken shell force loading position of peanut pods significant.(4) Through previous theoretical research and experimental results, proposed legislation cone design cell breeding peanut shelling device, and it gives the vertical cone cell breeding peanut shelling device key component of the design basis, and each part was related design.(5) To measure the results of triaxial peanut pod size, Poisson’s ratio, elastic modulus, density, and other related physical parameters as the basis for the opposition motion cone cell breeding peanut shelling device was simulated, focusing viewed particles in the collision during the distribution of the particles, as well as during exercise motion vector peanut peanut pods to give the movement direction substantially perpendicular to the peanut pods and Grid type gravure screen directions to meet the design requirements of the husking apparatus verified off feasibility and rationality of housing means for the future design of peanut shelling device provides data movement and other particles collide with the traditional design methods do not have the relevant.
