The sealing material 7 is provided over the lower end edge 41 as shown in FIG. Specifically, the sealing material 7 is placed on a mounting angle 71 laid on the lower edge 41 as shown in FIG. 3, and one end of the sealing material 7 is connected to the mounting angle 71 by a stopper 72. The thin portion 7a is firmly held by bolts 73 or the like.

  In the state where the lower bottom portion 51 is joined to the lower end edge 41, the thick portion 7b is pressed against the bottom surface of the lower bottom portion 51 of the sealing material 7, thereby sealing the joint portion of both.

  The joining structure and the sealing structure between the inclined edge 42 and the inclined portion 52 of the push plate 5 are the same as those described above.

  The sub-plate 6 is for filling a gap generated at the upper part of the entrance / exit 4 when the push plate 5 is arranged at the lower part of the entrance / exit 4 as described above. The sub-plate 6 is closed at the upper part of the entrance / exit 4. A pair of left and right flange members 61 are provided for securing the sub-plate 6 in a state where the sub-plate 6 is secured. The eaves member 61 is detachable from the sub-plate 6 by a pair of telescopic cylinders (not shown) provided on the left and right sides of the compactor A, which will be described later.

  The sub-plate 6 is provided with a holding means 8 for stably holding the push plate 5 in the above-mentioned joined state at the lower part of the entrance / exit 4.

  As shown in FIG. 4, the holding means 8 includes a pressing member 81 slidably provided on the upper and lower sides of the sub plate 6 such that a lower end portion 81 a protrudes below the sub plate 6, and the pressing member 81. And a spring 82 provided on the peripheral surface of the member 81 and biasing the pressing member 81 downward. As a result, when the inlet / outlet 4 is closed by the sub-plate 6 and the push plate 5, the lower end portion 81 a of the pressing member 81 presses the push plate 5 downward by the repulsive force of the spring 82. It is made to hold | maintain in the stable state which did not drop | omit fitted in the lower part of 4. As shown in FIG.

  The container 1 is provided with an engagement pin (not shown) on the upper portion of the front wall, and a hook of a cargo handling device (not shown) of the container cargo handling vehicle is engaged with the engagement pin so that the vehicle is driven by the cargo handling device. The vehicle can be loaded onto the vehicle body, and conversely, the vehicle can be lowered from the vehicle body onto a moving carriage of a facility equipped with a compactor, which will be described later, or on the ground.

  In addition, the load (dust) in the container 1 can be discharged to the outside by opening the tailgate 2 by tilting (dumping) the container 1 backward on the vehicle body by the cargo handling device.

  On the other hand, the container 1 configured as described above has a rear portion (tail gate 2 side) detachably attached to a compactor A as shown in FIG. Inside the compactor A is provided an extrusion plate A2 that reciprocates with a hydraulic cylinder A1. When the container 1 and the compactor A are connected, the dust introduced from the hopper A3 provided at the top is pushed out by the pusher plate A2 toward the pusher A5 at the front end of the compactor A together with the push plate 5. The container is compressed and transferred into the container 1 through the inlet / outlet 4 communicating with the outlet A4.

  Specifically, for example, a movable carriage (not shown) is provided in front of the compactor A so as to be movable in a direction perpendicular to the direction in which the container 1 is connected. The container 1 is unloaded from the container handling vehicle (not shown) on the movable carriage, After the container 1 is arranged in front of the compactor A by the moving carriage, the container 1 is captured and drawn by a connecting cylinder (not shown) provided at the center of the lower surface of the compactor A, or the container 1 after filling is pushed out. ing. In this case, the container 1 is moved via wheels (not shown) provided on the front, rear, left and right of the bottom so that the container 1 can be smoothly pulled or pushed out by the connecting cylinder. .

  When the tailgate 2 of the container 1 is connected to the front end of the compactor A, the push plate 5 is engaged with the extrusion plate A2 of the compactor A so that the inlet / outlet 4 and the extrusion port A4 of the compactor A communicate (connect). )

  At this time, the push plate 5 is connected to the extrusion plate A2 and the joined state at the entrance 4 is released. Specifically, the push plate connecting portion of the extrusion plate A2 is provided with an elevating mechanism A5, and the push plate 5 is moved upward at the entrance / exit 4 by the elevating mechanism A5. As a result, the push plate 5 is released from the lower part of the entrance / exit 4, and the push plate 5 can be reciprocated between the compactor A and the container 1 for the reciprocating motion of the extrusion plate A <b> 2.

  At the same time, on the side of the sub-plate 6, the eaves member 61 is pulled out by extension of the telescopic cylinder to release the locked state of the sub-plate 6 at the entrance / exit 4.

The sub plate 6 is integrally connected to a moving mechanism (not shown) provided on the compactor A side, and is moved upward by the moving mechanism. As a result, a space corresponding to the amount of movement of the sub-plate 6 is generated in the upper part of the push plate 5, and the holding means 8 is also moved upward and detached from the push plate 5. Can be detached by releasing the push plate 5 from the joint.
Then, the container 1 is connected to the compactor A in this way, and the push plate 5 is reciprocated between the compactor A and the container 1 by the reciprocating motion of the extrusion plate A2, so that it is introduced from the hopper A3 of the compactor A. The collected dust is compressed and transferred to the inside of the container 1 through the extrusion port A4 and the entrance 4. That is, the push plate 5 is configured to substantially compress and transfer the dust.

  At this time, the dust can be smoothly packed into the container 1 by the push plate 5 while preventing the dust from being caught by the space generated by the upward movement of the sub-plate 6.

  In addition to the mechanisms described above, a tying mechanism for tying and holding the tailgate 2 in a closed state, and a fixing mechanism for fixing and holding the container 1 connected to the compactor A so as not to move are also provided. ing.

  Since the push plate 5 is arranged at the entrance / exit 4 of the container 1 in this manner, when the container 1 is compressed and packed with dust, a lot of sewage contained in the dust is collected on the bottom surface of the container 1. Even when the container 1 is inclined when the container 1 is unloaded between the container handling vehicle and the equipment in such a state, the sealing material 7 can reliably prevent the sewage from leaking to the outside, Deterioration of the surrounding work environment due to leakage of sewage can be reliably prevented.

  Note that the above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof.

  For example, the holding means 8 is not limited to the pinned pressing member 81 as in the present embodiment, and the number of pressing members 81 is not limited to one.
