摘要/Abstract

摘要： 针对丘陵山区茶树管理中修剪环节存在劳动强度大、适用机器少、作业环境差等问题,设计了一款纯电动自走轻简型悬臂茶树修剪机。基于茶园管理农艺要求,分析了整机结构及工作原理,创新设计了“折叠+旋转”的悬臂结构,进行了关节运动学仿真分析,对行走装置关键部件进行了理论分析和选型计算,样机试制后开展了爬坡和田间性能试验。试验结果显示,修剪机可顺利通过25°斜坡,漏剪率为0.55%,修剪撕裂率为1.36%,各项性能指标均符合DG/T 110—2024《茶树修剪机》的要求。本研究结果可为丘陵山区茶树修剪提供新的参考依据。

Abstract: To address issues of high labor intensity, few applicable machines and poor working conditionsin tea plant management in hilly and mountainous areas, a self-propelled lightweight cantilever tea pruning machine was designed. Based on the agronomic requirements for tea garden management, the overall structure and working principle of the machine were analyzed. An innovative “folding + rotation” arm structure was designed and dynamic simulation analysis was carried out. The key components of the walking device were theoretically analyzed and selected. After creating the prototype, field slope climbing performance test and tea plant pruning test were carried out. The results show that the maximum climbing ability of the pruning machine was 25°, the working performance of the pruning machine was stable, the missed detection rate was 0.55%, the tear rate of tea plants after pruning was 1.36%, and all performance indicators met the requirements of DG/T 110—2024. This study provided a new solution for tea plant pruning in hilly and mountainous areas.
