摘　　要：为了探索和优化茶园履带掘耕机的耕作质量,得到最佳工作参数,对茶园履带掘耕机的耕作原理进行了运动学分析,并以根深为目标优化得到多组杆件参数;在重耕漏耕的理论分析基础上,以耕深、重耕漏耕量作为试验指标,以杆件组合、前进速度和曲柄转速作为试验因素设计正交试验,得到最佳工作参数组合;最后,进行了样机试制和实地验证。结果表明:曲柄l 3=81 mm、连杆l 4=175 mm、曲柄转速115 r/min、作业速度450 mm/s的工作参数组合为相对最佳组合。In order to explore and optimize the cultivation quality of the tiller machine for tea plantations,obtain optimal operating parameters,the cultivation principle of tiller machine was analyzed in kinematics,and several groups of bar parameters were optimized with the goal of root depth.Based on the theoretical analysis,using root depth and missed plowing as experimental indicators,orthogonal experiments were designed to obtain the optimal working parameter combination by rod combination,forward speed and crank speed as experimental factors.Finally,through prototype trial production and on-site verification.The results showed that:crank l 3=81 mm,connecting rod l 4=175 mm,crank speed was 115 r/min,forward speed was 450 mm/s,these parameter combinations could meet the design requirements.
