A plurality of injection holes 63 as shown in FIG. 5 are provided at predetermined intervals over the entire length of the pipe member 62, and communicate with the upper end thereof as shown in FIG. A tube 64 is connected.

The communication pipe 64 is guided to, for example, a front portion of the container body 4 and communicates with a cleaning liquid supply device 7 (see FIG. 6) as a supply source provided on the vehicle frame 11 side.

As shown in the piping diagram of FIG. 6, the cleaning liquid supply device 7 includes a tank 71 for storing a cleaning liquid such as water, and a hydraulic pump 73 driven by an electric motor 72. The suction port of the hydraulic pump 73 has a suction port. The tank 71 is connected to the communication pipe 64 via a suction pipe 74 and a discharge port of a hydraulic pump 73 is connected to the communication pipe 64 via a supply pipe 75.

The connecting portion between the supply pipe 75 and the communication pipe 64 is detachable via a connecting member 76 such as a coupling so that the vehicle frame 11 and the container 3 can be separated from each other at the connecting portion. ing.

The operation of the electric motor 72 is controlled by a control device 78 based on the operation of an operation section 77, and the driving of a hydraulic pump 73 is controlled accordingly.

The reference numeral 79 shown in FIG.
The cleaning liquid can be returned to the tank 71 from the unload valve 79 through the return pipe 79a.

Further, an appropriate sealing mechanism is provided so that the input port 41 is also hermetically closed when the opening / closing lid 43 is closed. That is, the container body 4 is hermetically closed when the opening / closing lid 43 and the opening / closing gate 45 are closed.

The fixed frame 5 is formed in a rectangular parallelepiped as a whole as shown in FIGS. 1 and 2, and is fixedly integrated with the container body 4. At each of four corners on the bottom surface of the fixed frame 5, a locking portion 51 is provided, which is detachable by a container connecting fitting (not shown) at each locking portion 22 provided on the tilting frame 2 shown in FIG. 1. ing. Therefore,
The container 3 is arranged at a predetermined position on the tilting frame 2 and

It can be stably mounted on the top.

The container 3 can be loaded not only on the container transport vehicle 1 but also on a container transport ship (not shown). In this state, it can be fixed and stably placed.

The container 3 is unloaded between the container carrier 1 and the container carrier by lifting and moving the container 3 using a crane.

For example, when transferring garbage stored in a certain garbage storage site to a final disposal site or the like, the garbage in the garbage storage site is inserted into the container 3 of the container transport vehicle 1 through the input port 4.
Then, the container carrier 1 transports the container to the port where the container carrier is anchored. next,
The container 3 is transferred from the container carrier 1 to a container carrier by a crane, and transported to the nearest port of the final disposal site by the container carrier. At the port, the container 3 is reloaded from the container carrier to the container transport vehicle 1 by a crane, and the container 3 is transported to the final disposal site by the container transport vehicle 1.

When the container 3 is transported in this way, the inside of the container 3 is closed in a closed state by the opening / closing lid 43 and the opening / closing gate 45, so that the garbage and odor inside do not leak to the outside. Since watertightness is ensured, garbage and the like do not leak to the outside, and can be transported sanitarily without adversely affecting the surrounding environment.

When discharging the dust in the container 3, the container 3 is placed on the vehicle frame 11 via the tilting frame 2, and the locking of the opening / closing gate 45 is released. Is tilted about the rear hinge 21 to tilt the container 3 together with the tilting frame 2 as shown by a two-dot chain line in FIG. As a result, the opening / closing gate 45 is opened downward around the upper hinge 44, and the dust inside is discharged from the outlet 42 opened by the downward opening.

In order to discharge the dust, the dust easily adheres to the peripheral edge of the rear surface of the container body 4 forming the opening / closing gate 45 and the discharge port 42. If dust adheres to these parts, particularly to the seal mechanism 6, when the opening / closing gate 45 is closed, the dust is removed from the packing material 61 and the pipe material 6 of the seal mechanism 6.
2 and the sealing function such as water tightness is significantly reduced.

For this reason, after discharging the dust, the seal mechanism 6 is cleaned as follows. When the container 3 is folded down to the original horizontal position together with the tilting frame 2, the container 3 is once folded down before being placed at this horizontal position, that is, before the opening / closing gate 45 closes the discharge port 42 as shown in FIG. To stop. Subsequently, in this state, the hydraulic pump 73 of the cleaning liquid supply device 7 is driven by operating the electric motor 72 by the operation unit 77 to supply the cleaning liquid such as water in the tank 71 to the supply pipe 7.
5. The pressure is fed into the pipe member 62 through the communication pipe 64, and is injected from the injection hole 63 of the pipe member 62 toward the packing member 61.

By the injection of the cleaning liquid, the packing material 61 is formed.
The dust adhering to the nozzles is removed, and the dust adhering around the injection holes 63 is also removed. Thereafter, the container 3 is folded down to the original horizontal position together with the tilting frame 2, so that the opening / closing gate 45 closes the discharge port 42 via the seal mechanism 6, and is secured by the securing device in the closed state.

After the dust is discharged from the container 3 as described above, the dust adhering to the seal mechanism 6 is removed just before closing the opening / closing gate 45, whereby the sealing function is reduced due to the dust entering the seal mechanism 6. Can be reliably prevented. In addition, since the cleaning operation is not performed manually by the operator as in the related art, but is performed by injecting the cleaning liquid, the operation can be efficiently performed in the flow of the discharging operation without burdening the operator.

[0035]

As described above, according to the apparatus for cleaning a sealing mechanism of a container opening / closing gate according to the present invention, the sealing mechanism is provided between the packing member provided along the joint on the container body side and the packing member. A hollow pressure-contact material provided on an opening / closing gate so as to press against the packing material, wherein the pressure-contact material has a plurality of injection holes formed at predetermined intervals in a portion facing the packing material. Since the supply source for supplying the cleaning liquid into the pressure contact material is communicated with the pressure source, the cleaning liquid supplied from the supply source into the pressure contact material can be ejected from the ejection holes to remove dust adhering to the seal mechanism.
As a result, it is possible to reliably prevent the sealing function from deteriorating due to dust entering the sealing mechanism. In addition, since the cleaning is not performed manually by the operator as in the related art, but is performed by spraying the cleaning liquid, there is no burden on the worker.
It can be performed efficiently in the flow of the discharge work.
