Design and Test of Vibration Excavation Device of Cyperus esculentus Harvester Based on EDEM-ADAMS Coupling
摘要
Abstract
Aiming at the problems of difficult mechanical operation and high energy consumption during the harvesting of Cyperus esculentus,a vibration excavation device for Cyperus esculentus combining rotary tillage excavation and vibration excavation was designed.The structure and parameters of the above key components were designed.The discrete element model of Cyperus esculentus,grass and soil bin were established.The excavation process of Cyperus esculentus was simula-ted by EDEM-ADAMS coupling method.The rotation speed of rotary blade,amplitude and vibration frequency of vibra-ting screen were taken as experimental factors,and the orthogonal simulation test design was carried out with the transport efficiency of Cyperus esculentus,sand transport efficiency,sand leakage rate and operation power as experimental inde-xes.The effects of operation parameters such as rotation speed,amplitude and vibration frequency of rotary blade on ex-cavation effect were explored.The simulation results showed that when the rotation speed of rotary blade was 370 r/min,the amplitude was 9 mm,and the vibration frequency was 12.5 Hz,the conveying efficiency of Cyperus esculentus could reach 97.8%.At this time,the damage rate,root-grass crushing rate and root-grass soil rate of Cyperus esculentus in the field test were 2.67%,65.51%and 59.52%,respectively,which could meet the agronomic requirements of Cype-rus esculentus harvest and provide reference for the design of Cyperus esculentus vibration digging device.关键词
