and at present the research on rotation mechanism in the backhoe device still blank basically at home.
目前,国内对挖掘装载机反铲装置回转机构的研究还基本上是空白的。
a series of feasible scheme of backhoe device is given out. the method of innovative design provides a powerful tool for avoidings. existing mechanisms which have patent protection.
并给出了液压挖掘机构反铲装置的一系列可行方案,该创新设计方法为回避已受专利保护的现有机构提供了强有力的工具。
backhoe device is an important part of hydraulic excavator to achieve its functions, its structure affects the performance of excavator directly.
反铲装置作为液压挖掘机实现其各项功能的重要组成部分,它的结构直接影响到挖掘机的工作性能。
now wz25-20 is regarded as an example, its backhoe device consists of moving arm, pole, bucket, guiding organization and rotation mechanism.
把wz25-20挖掘装载机作为研究样机,其反铲挖掘装置主要由动臂、斗桿、铲斗、导轨机构、回转机构和连接架组成。
