为解决各种山地果园中除草难度大、除草效率低、难以实现机械化等问题,研制高效的新型除草机具有重大意义。为能够更好地适应南方果园的复杂地形,提高除草率,设计的除草机采用履带式行走机构和新型双轴式除草作业头机构;利用Inventor三维软件对除草机整机进行设计建模,并验证整机结构的合理性;对除草机关键零部件除草作业头进行设计,并通过力学分析验证了除草刀的适用性,确定除草作业头的关键性能参数。通过现场试验分析了除草甩刀的转速、甩刀质量以及底盘行走速度对除草机除草效率的影响,通过分析试验数据得出：当行走速度为0.5 m/s、转速为1 600 r/min、甩刀质量为0.347 kg时,除草效率以及防...

In order to solve the weeding problems in the context of difficult operation, low efficiency and hard to achieve mechanization in various mountain orchards, it is significant to develop an efficient type of weeding machine. Through the analysis on the development and research status of domestic and foreign weeders, it was found that both the existing weeders at home and abroad can not adapt well to the complex terrain of hilly hills in the south of China. By analyzing the physical characteristics of the operating objects and the on-site investigation of the operating environ-ment, the design b...
