基于EDEM仿真的机械式辣椒精量排种装置设计与试验
Design and Experiment of Precision Mechanical Metering Device for Pepper Seed Based on EDEM
摘要
Abstract
Aiming at the problems of high labor intensity,low seeding efficiency and high labor cost existing in manual hill-drop seeding in pepper floating seedling raising,this paper proposes a pepper seed precision mechanical metering device adapted to pepper floating seedling raising on the basis of magnetic return-type seed metering mechanism,and the design and motion analysis of the key structure was carried out using SOLIDWORKS and other software and simulation of the seed metering device was conducted by using EDEM.Taking crank rotary speed,seeds quantity,and crank diameter as factors,and the single grain rate,reseeding rate,and missed seeding rate as evaluation indexes,the response surface test,using Box-Behnken design,was conducted and the results were analyzed.The parameter combinations of the seed metering device are evaluated combining weight with membership degree.The optimal parameters combination for the seed metering device is determined to be crank rotary speed of 260 r∙min-1,seed quantity of 4 000 grains,and crank diameter of 28 mm.The single grain rate,reseeding rate and missed seeding rate of the prototype test were 91.46%,7.29%and 1.25%,respectively,which met the technical requirements of pepper floating seedling production.关键词
