胡萝卜联合收获挖掘部件运动及力学特性分析
Analysis of Motiom and Mechanical Properties of Digging Parts of Carrot Combine Harvester
摘要
Abstract
Aiming at the problems of difficult digging and shoveling of carrot combine harvester,inaccurate clamping caused by digging backwater,large digging resistance and so on,motion and mechanical properties of carrot digging parts was studied in this paper.The mathematical model of the soil penetration characteristics of the digging parts and the me-chanical characteristics of the interaction with the soil is constructed,and the correlation between the soil penetration an-gle,the soil penetration stroke,the excavation resistance and the structure of the excavation parts were theoretically ana-lyzed.By using of EDEM discrete element simulation software,the penetration stroke and mechanical characteristics of shovel soil interaction of excavation shovel were studied and analyzed,and the field verification test was carried out.The results show that the soil blocking height and excavation resistance are directly proportional to the penetration angle.When the final penetration angle is 14 °～22 °,the net yield of carrot is≥98%and the damage rate is≤1.5%.The blocking phenomenon is not significant and meets the harvest requirements.关键词
