The container 11 can be mounted on the vehicle body frame 101 while being lifted by the attaching / detaching mechanism 102, or the mounted container 11 can be dropped on the ground.

Next, the container 11 constructed as described above is used.
Will be described. First, in FIG. 3, the oil pump 73 is activated to supply the pressure oil to the hydraulic motor 67, and the rotation shaft 68 of the motor 67 is rotated in the reverse direction. Then, the first to fourth ball screws 52 to 55 are reversely rotated by the driving sprocket wheels 69 and 70, the chains 71 and 72, and the driven sprocket wheels 61 to 64, and discarded by the first to fourth ball nuts 57 to 60. The object moving plate 41 is translated rearward. Although not shown, the stop operation of the movable plate 41 at the last retreat position is performed by a limit switch provided on the frame 12 side so as to detect the movable plate 41.
This is performed when 1 is detected and the pump 73 is stopped.

In this state, waste is put into the storage space 40 through the inlet 24. When the waste is accumulated in the space 40 near the inlet 24 so as to be crowded, the hydraulic motor 67 is rotated forward to move the waste moving plate 41 forward. At this time,
Since the lifting rods 83 to 83 for return prevention are lifted upward, the waste does not interfere with the rod 83, and the waste moves forward with the waste moving plate 41, that is, the open / close lid 32.
Moved to the side. The waste moved forward by the waste moving plate 41 is compressed between the open / close lid 32 and its volume is reduced.

For adjusting the pressing force of the waste by moving the movable plate 41 forward, for example, the pressure of the pressure oil supplied to the hydraulic motor 67 is detected by a sensor (not shown), and this is set to a set value. In this case, the operation is performed by stopping the oil pump 73.

When the forward movement of the waste moving plate 41 is stopped, the hydraulic motor 67 is switched to the reverse rotation, and the motor 87 is activated to lower the lifting rod 83 and stop at the return preventing position. .

After compressing the waste, the waste transfer plate 4
When 1 is further moved backward beyond the lifting rod 83,
If the compressed waste is an elastically deformable member, the waste tends to return to the inlet 24 side. However, this is prevented by the lifting rods 83-83.

When the above-described waste input and compression operations are repeated and the waste in the container 11 is full, the lid 26 is closed, and the lifting rod 83 is kept in the return preventing position. Will be retained.

Thereafter, the container 11 is moved to the vehicle body frame 101 by the attaching / detaching mechanism 102 of the truck 100 shown in FIG.
Mounted on top. When the container 11 is transported to the destination by the truck, the container 1 remains mounted on the truck.
The waste in 1 is discharged to a predetermined place. The waste may be discharged after unloading the container from the truck. This waste discharging operation is performed as follows.

When the lock mechanism 34 of the opening / closing lid 32 is released,
The lid 32 is lifted upward. In this state, when the hydraulic motor 67 is driven, the first to fourth ball screws 52 to
55 is synchronously rotated forward and the waste moving plate 41 is advanced from the last retreat position. For this reason, the waste in the container 11 is pushed forward by the moving plate 41, and
Is discharged to the outside.

Next, the container 11 constructed as described above is used.
The effects of the above are listed together with the configuration. (1) In the above embodiment, the first to fourth ball screws 52 to 55 are provided at predetermined positions of the frame 12, and the first to fourth ball nuts 57 to 60 screwed to the respective ball screws 52 to 55. The waste moving plate 41 was mounted so as to be able to move in the front-rear direction. Therefore, there is no need to use an actuator such as a cylinder that is long in the front-rear direction as a mechanism for moving the waste moving plate 41 in parallel.
7, the space occupied in the front-rear direction can be reduced. Therefore, the waste storage space 40 in the container 11 can be set large.
