ENERGY RECOVERY AND REUSE SYSTEM FOR LOADER-DIGGER AND CONTROL METHOD THEREFOR, AND LOADER-DIGGER
The present disclosure relates to a backhoe loader energy recovery and reuse system and a control method thereof, and a backhoe loader, wherein the system comprises: an actuator, configured to drive a working device to perform an action with hydraulic oil as a medium, and having a first cavity and a second cavity; a reversing valve, having a first working oil port communicated with the first cavity and a second working oil port communicated with the second cavity, the reversing valve being configured to reverse the actuator; a stabilizing valve group, having 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 being communicated with the first cavity and the second cavity, respectively, and the third oil port being communicated with an oil tank; and an energy storage part, communicated with the fourth oil port and configured to store hydraulic energy; wherein the first oil port and the third oil port have a first communication state therebetween, in which the hydraulic oil in the first cavity can enter the oil tank; the second oil port and the fourth oil port can be selectively connected or disconnected, and in a connected state, the second cavity is communicated with the energy storage part.
