Claims

[Scope of claim for utility model registration] 1. Inside the tailgate provided at the opening of the packing box,
There is a rotating plate that scrapes up the garbage thrown into the sump at the bottom of the tailgate to the level of the opening of the cargo box, and the rotating plate can freely move forward and backward to push the dirt on the rotating plate toward the opening of the cargo box. A garbage collection vehicle having a supported pushing plate and a device for stopping a driving device of the pushing plate by activation of a pushing plate backward limit position detection device, in which the pushing plate can be moved rearward from the backward limit position. A garbage collection vehicle, characterized in that it is provided with an emergency actuation device that operates a drive device for the pushing plate to displace the pushing plate rearward from the backward limit position regardless of the operation of the backward limit position detection device. 2 The push plate backward limit position detection device is configured with a limit switch, and the push plate backward drive device is configured by a limit switch.
Connect to the power supply through the normally open contact of the limit switch, the push plate retraction operation switch, and the normally closed contact of the emergency switch, and connect the normally open contact on the emergency switch to the push plate retraction drive device without going through the limit switch. A garbage collection vehicle according to claim 1, wherein the emergency operating device is constituted by a circuit that performs the following steps. 3. Garbage according to claim 2 of the utility model registration claim, in which the normally open contact provided on the emergency switch is connected to the push plate retraction drive device through another normally open contact provided on the push plate retraction operation switch. Collection car.
