Claims

[Scope of Utility Model Registration Claim] Hydraulic/electrical system in which a discharge cylinder for discharging dust from a storage box, an opening/closing cylinder for opening and closing the input box, and a locking cylinder for locking the input box are each connected to a hydraulic power source via a switching valve. In the circuit, three-position type first and second switching valves connected to the discharge cylinder and the opening/closing cylinder and capable of telescopically switching the respective cylinders are connected in series to the hydraulic power source, and are connected to the locking cylinder. A two-position type third switching valve that can telescopically switch the cylinder is connected in parallel, and has a normally closed and open contact, and a switch that opens and closes each contact after a predetermined period of time has elapsed. inserting the electric circuit for switching the switching valve to the forward drive position and the electric circuit for switching the second switching valve to the open position of the input box, and simultaneously closing the electric circuit and the electric line for switching the third switching valve to the unlocked position when the input box is opened; It is characterized by the provision of a hydraulic/electrical circuit that simultaneously closes the electric circuit that switches the second switching valve to the loading box lowering position when the loading box is closed, and the electric circuit that switches the third switching valve to the locking position when the loading box completes lowering. A loading box opening/closing device for a garbage collection vehicle.
