Hydraulic oil path system

The utility model discloses a hydraulic oil way system which comprises an oil pump, a plurality of oil way blocks connected with an outlet of the oil pump and an oil recovery device connected with pressure relief openings of the oil way blocks. When the hydraulic oil way system is in a cleaning state, a proportional reversing valve connected to a high-pressure oil way is replaced with a cleaning device, and the cleaning device comprises a high-pressure oil inlet communicated with the oil pump, a plurality of first connecting ports used for being connected with different high-pressure oil waysand a second connecting port connected with the pressure relief oil way. Wherein the high-pressure oil inlet is communicated with one of the first connecting ports, so that high-pressure oil enters the corresponding high-pressure oil path to be circularly cleaned, and the high-pressure oil path corresponding to the other first connecting ports is not communicated with the pressure relief oil path.According to the hydrauli
