摘　　要：三节臂式破碎反铲机构集成了破碎和铲装功能,作业过程中不需要进行属具换装,匹配煤矿井下空间受限、负载大的使用需求。针对破碎、挖掘2种作业工况,分析了最大破碎高度、最大破碎宽度、最大破碎深度、挖掘作业4种典型作业姿态下,各驱动油缸的受力特性,并以此为依据完成了各油缸的参数设计。The three arm type crushing backhoe mechanism integrates both crushing and shoveling functions,working equipment do not need to be changed during operation,match the coal mine environment with limited space and large load.For crushing and shoveling two working conditions,four typical working attitudes of maximum crushing height,maximum crushing width,maximum crushing depth and excavation operation were analyzed,the mechanical characteristics of each drive cylinder were obtained,and the parameters of each cylinder were designed.
