一种果园中耕避障除草机的设计与试验
Design and Experiment of Orchard Obstacle Avoidance Weeding Cultivator
摘要
Abstract
An orchard obstacle avoidance inter-row weeding cultivator was designed to address the problem of difficult weed removal between the tree trunks in the orchard,which mainly included inter-row weeding mechanism,intra-row weeding mechanism,hydraulic obstacle avoidance components,and could achieve inter-row and intra-row cultivating and weeding operations.The obstacle avoidance of the intra-row weeding mechanism was achieved by the linkage of the touch spring obstacle avoidance rod and the hydraulic cylinder-driven four-bar linkage mechanism.Using EDEM software,three-factor three-level orthogonal simulation experiments and operational parameter optimization were conducted with weeding wheel rotation speed,soil tillage depth and forward speed as indicators.The optimal parameter combination was found as follows:the weeding wheel rotation speed of 500 r·min-1,the soil tillage depth of 80 mm,and the forward speed of 1.2 m·s-1.Field experiments of the prototype were conducted,with a weed avoidance rate of 100%,a missed tillage rate of 3.44%,no damage,an average tillage depth of 80.9 mm,a tillage depth stability coefficient of 97.8%,and a productivity ranging from 0.86 to 1.38 hm2·h-1.Above results could provide reference for the design of obstacle avoidance and weeding machines in orchards.关键词
