Loader-digger energy recycling system, control method and loader-digger
The invention relates to an energy recycling system of a backhoe loader, a control method and the backhoe loader, and the system comprises an executing mechanism which is used for driving a working device to execute actions by taking hydraulic oil as a medium and is provided with a first cavity and a second cavity; the reversing valve is provided with a first working oil port and a second working oil port, the first working oil port is communicated with the first cavity, the second working oil port is communicated with the second cavity, and the reversing valve is used for reversing the executing mechanism; the stabilizing valve group is provided with a first oil port, a second oil port, a third oil port and a fourth oil port, the first oil port and the second oil port are communicated with the first cavity and the second cavity respectively, and the third oil port is communicated with the oil tank; the energy storage component is communicated with the fourth oil port and is used for storing hydraulic energy; a first communicating state exists between the first oil port and the third oil port, and in the first communicating state, hydraulic oil in the first cavity can enter the oil tank; the second oil port and the fourth oil port are selectively connected or disconnected, and the second cavity is communicated with the energy storage component in the connected state.
本公开涉及一种挖掘装载机能量回收再利用系统及控制方法、挖掘装载机，其中系统包括：执行机构，用于以液压油为介质驱动工作装置执行动作，具有第一腔和第二腔；换向阀，具有第一工作油口和第二工作油口，第一工作油口与第一腔连通，第二工作油口与第二腔连通，换向阀用于使执行机构换向；稳定阀组，具有第一油口、第二油口、第三油口和第四油口，第一油口和第二油口分别与第一腔和第二腔连通，第三油口与油箱连通；和蓄能部件，与第四油口连通，用于存储液压能；其中，第一油口与第三油口之间具有第一连通状态，在第一连通状态下，第一腔的液压油可进入油箱；第二油口与第四油口之间可选择地接通或断开，在接通状态下使第二腔与蓄能部件连通。
