The container body is mounted so as to be able to be loaded and unloaded by a fluid-driven loading / unloading device provided in the vehicle, such as a waste dumping room provided in the basement of an apartment or building. After being mounted on the vehicle and transported, after being lowered from the vehicle to the ground by the loading / unloading device of the vehicle, a pair of fluid cylinders on the container main body side are disposed on the ground side provided in the waste dumping chamber. It is connected so that the fluid is supplied and discharged through the electromagnetic switching valve and the communication pipe with the fluid supply / discharge device, and the waste put in from the above-mentioned inlet is pushed into the container body by the swing of the pushing plate. Then, when the container body is full of waste,
The connection to the fluid supply / discharge device on the ground side via the electromagnetic switching valve and the communication pipe is cut off, and the container body is loaded and unloaded, mounted on a vehicle by the device, and transported to a waste disposal site or the like. In this case, the electromagnetic switching valve is provided in the fluid supply / discharge device on the ground side of the waste dumping chamber, and the electromagnetic switching valve is switched by the power supply of the waste dumping chamber.

[0003]

However, in the above-mentioned conventional container with a push-in device, the electromagnetic switching valve is provided in the fluid supply / discharge device on the ground side in the waste dumping room (above the ground). The supply and discharge of the fluid to and from the fluid cylinder are performed via a communication pipe with the electromagnetic switching valve on the ground side. Therefore, for example, with the container body mounted on a vehicle, a pair of fluid cylinders on the container body side, and a fluid supply / discharge device on the vehicle side for driving the loading / unloading device of the vehicle, the electromagnetic switching valve and the communication pipe. Even if it is connected so that fluid is supplied / discharged via this, since the electromagnetic switching valve of the fluid supply / discharge device on the vehicle side is dedicated to lowering the volume of the container, the pair of fluid cylinders on the container body side Can not supply and discharge fluid properly. In addition, the power source on the vehicle side is typically a DC (direct current) 24
V, while the power supply on the ground side is AC (al
Since the power supply is set to 200 V and the power supplies are different from each other, the power supply on the vehicle side cannot be used as it is as the power supply on the container side using the power supply on the ground. From the above, in a place where there is no fluid supply / discharge device provided with an electromagnetic switching valve dedicated to supplying / discharging fluid to / from a pair of fluid cylinders on the container body side, the pushing device cannot be operated and the container body is installed. The location was naturally limited.

Further, since the fluid after switching by the electromagnetic switching valve is supplied to and discharged from the pair of fluid cylinders, a fluid supply / discharge port of the fluid cylinder for connecting a communication pipe to the pair of fluid cylinders. Three fluid supply ports for individually supplying fluid to a pair of fluid cylinders and at least one fluid discharge port for discharging fluid from the pair of fluid cylinders are required. And
Connecting and disconnecting the fluid supply / discharge ports (the ports dedicated to fluid supply and the ports dedicated to fluid discharge) between the ground-side fluid supply / discharge device and the push-in device via the communication pipe is very troublesome.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a push-in device which operates only by connection through a communication pipe and a power supply to a fluid supply / discharge device on a vehicle side.
