Abstract：Anorchardobstacleavoidance inter-rowweedingcultivator was designedtoaddressthe problemofdificult weed removalbetweenthe tre trunks in the orchard，which mainly included inter-row weeding mechanism，intrarow weeding mechanism，hydraulic obstacle avoidance components，and could achieve inter-row and intra-row cultivating and weding operations.The obstacle avoidanceof the intra-row weeding mechanism was achieved by the linkage ofthe touch spring obstacle avoidancerodand the hydrauliccylinder-driven four-barlinkage mechanism. UsingEDEM software，thre-factor thre-level orthogonal simulation experimentsand 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 folows：the weeding wheel rotation speed of 500r?min-1 ，the soil tillage depth of 80 mm，and the forward speed of1.2m* s-1 .Field experiments of the prototype were conducted，with a weed avoidance rate of 100% ，amissed 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 1.38hm2?h-1 . Above results could provide reference for the design of obstacle avoidance and weeding machines in orchards.
