Sieving Analysis and Experiment of Threshing Material of Cyperus Esculentus Based on Discrete Element Method
摘要
Abstract
As a new type of oil crop,the sieving of the threshing material from the combine harvester is an important part of mechanized harvesting,and in order to improve the sieving effect,this study takes the sample material of the Cyperus esculentus sampled in the field as the research object,and determines the quality fraction of the sample material Cyperus esculentus particle fraction is 76.8%,and the particle size is 13-18mm;establishes the discrete element model of the material particles,and imports the EDEM software for different sieve surface simulation test analysis,the best mesh size of the weave screen is 18mm,the sieving effect is 91.46%;the best mesh size of the punching sieve is 20mm,the sie-ving effect is 87.77%;the best mesh size of the fish scale screen is 20mm,the sieving effect is 87.47%;for the bench sieving test analysis,the selection of the mesh size of 20mm preparation;The best overall sieving efficiency of 94.32%can be obtained.The conclusion of the study provides a theoretical basis for the design and optimization of the mecha-nized screening device for cyperus esculentus.关键词
