Hydraulic system of intelligent unloading equipment

The invention relates to the field of hydraulic systems, in particular to an intelligent unloading equipment hydraulic system. The hydraulic system of the intelligent unloading equipment comprises a piston rod, a pressure triggering mechanism and the like. The piston rod is connected with a pressure trigger mechanism. According to the hydraulic system of the intelligent unloading equipment, when goods are loaded on the goods loading platform, the pressure triggering mechanism is triggered and pushes the clamping piece to lock the elastic stretching mechanism and the auxiliary piston together, and under the intervention of the elastic stretching mechanism, the elastic stretching mechanism can stretch out of the auxiliary piston; the pressure value of the high-pressure hydraulic oil filled in the cylinder barrel does not need to exceed the maximum bearing pressure value set by a hydraulic system, when goods are suddenly transferred away during unloading, the pressure triggering mechanism unlocks the elastic str
