Experimental Study On Horizontal Small Breeding Peanut Shelling Machine

Sheller is the most important link in peanut production. Peanuts as a world and an important oil crop, and also the export trade in foreign currency in the most competitive agricultural production in the world’s core product. Shelling is caused peanut seed internal injury and shape broken or cracking of main processing link, but is processing and production get peanut seed process will by of key link, shelling mechanical on species with peanut of shelling need more strictly, face of peanut species quality resources precious, requirements test species data precision, planting of community number more, and each species community processing seed volume small, and peanut seed cannot mixed,, both guarantee each shelling job clear species convenient reliable, shelling injury and loss smaller, and has high of shelling job efficiency.Combined the National Natural Science Foundation named "peanut shell and the principle of mechanical damage,and the research on how to reduce the damage in the process of peanut shell"(The number of this project is 50775151), For currently peanut shelling machine General exists shelling rate low, and peanuts injury serious, shortcomings, in research peanut pod and the nuts physical mechanical characteristics of based Shang, research has drum-intaglio screen each other group distribution work of device, for has key parts structure and parameter of theory analysis and design, development has prototype and for has shelling performance test, determine has shelling device of best structure parameter, for in-depth research peanut and related material of shelling device provides has must of reference according to.Paper based on the literature review at home, using a combination of theoretical and experimental methods, the main research contents and conclusions were as follows:(1) Analysis China and the Liaoning province peanut production profile, on China peanut shelling mechanical equipment status and the shelling technology of development course of research analysis, antibody summary has existing peanut shelling mechanical main shelling parts of advantages and disadvantages, analysis summary currently China peanut seed in mechanical shelling process in the exists of several main injury features and injury of against, proposed design a efficient low loss of species with peanut shelling equipment on peanut industry development of major meaning.(2) Analysis of physical characteristics to determine parameters of typical varieties. Detailed determination of the flower, flower mound, flower sterile, United States Georgia 06G pod of peanut varieties and the nut size and other physical properties, and test results are analyzed. Shell plate width size choices, shell gap intaglio and screen space provides a theoretical basis for selection.(3) Universal materials testing machines to Mons flower, flower and shell the fertility related mechanical characteristics testing, testing demonstrated that peanut varieties, moisture content and position differences on the crushing force of law for shell prototype of the theoretical reference for the design parameters.(4) Design new horizontal species with peanut shelling machine, proposed horizontal species with peanut shelling machine of General design programme, used drum-intaglio screen group distribution of shelling device, for used this device of shelling drum and intaglio screen respectively began optimization design, and for peanut pod in shelling indoor of movement process for mechanical Shang of theory analysis, for paper on horizontal breeding with peanut shelling prototype of design processing provides has theory of support.(5)New horizontal shell with a peanut shelling machine performance testing, including a large number of single-factor experiment and parameters of orthogonal, horizontal type peanut shelling machine was studied indicators of main parameters on Shell peanut seed threshing performance and damage effects. Through orthogonal test playing board form, and intaglio screen form and playing board cut angle of parameter for optimization summary out took horizontal species with peanut shelling prototype the performance parameter on peanut seed shelling index of effect relationship, and obtained has effect test index of the parameter of significantly sex level and the primary and secondary order, determine has best parameter combination, and through validation sex test to test has parameter optimization Hou of machine shelling job work effect.
