The container Ct is provided with lower and upper locking devices Ll and Lu for preventing the lower bar-tacking member 30 on the main gate side and the upper bar-tacking member 31 on the sub-gate side from slipping out. Since these lock devices Ll and Lu both have the same structure, the structure of the lower lock device Ll on the main gate side will be explained in detail with reference to FIGS. 5 to 7. , an inner lock mechanism 43, and an outer lock mechanism 44. The inner lock mechanism 43 includes a lock lever 46 that is swingably supported on a pin 45 protruding from the side wall of the container Ct.
The lock spring 47 is stretched between the lock lever 46 and the side wall of the container Ct and biases the lock lever 46 to the locked position. As shown in FIG. 7, the lock lever 46 has a locking piece 46 ₁ formed in a hook shape, and the tip of this locking piece 46 ₁ is engaged with the bar-tacking rod of the lower bar-tacking member 30 by the elastic force of the locking spring 47. The locking position (FIG. 6), in which the bar-tacking rod 32 faces the end surface, and the unlocking position (FIG. 5), in which it does not face the end surface of the bar-tacking rod 32, can be swung between the locking position (FIG. 6), in which the lock release member 52 (to be described later) collides with the bar-tacking member 52, which will be described later. There is. In addition, the outer lock mechanism 44
On the outside of the inner lock mechanism 43, there is a lock lever 49 which is pivotally supported on the side wall of the container Ct by a pin 48, and a lock lever 49 which is stretched between the lock lever 49 and the side wall of the container Ct.

5) and an unlocked position (FIG. 5) in which the bar-tacking rod 32 does not face the end surface by abutment with an unlocking member 52, which will be described later.

Upper locking device Lu that locks sub-gate Gs
It has exactly the same structure as the lower locking device Ll, and the same members are given the same reference numerals.

Thus, the upper and lower locking devices Lu and Ll cooperate to lock the upper and lower barlock members 30 and 31.
It constitutes a double lock mechanism.

On the other hand, lock release members 52 are provided on both sides of the compactor main body 1 of the compactor Cp to simultaneously abut the upper and lower lock devices Lu and Ll to operate them both to the unlock position when the compactor Cp is connected to the container Ct. It will be done. As shown in FIGS. 1 and 5, the lock release member 52 is constructed by fixing an abutment piece 54 extending in the vertical direction to a bracket 53 fixed to the side surface of the compactor Cp. When the compactor Cp and the container Ct are connected, the abutting piece 54 abuts against the locking levers 46, 49 of the upper and lower locking devices Lu, Ll, and swings the levers 46, 49 to the release position.
The lower bar tacking members 31, 30 can be removed.

Next, the operation of this embodiment will be explained.

Now, when the container Ct is moved toward the front of the compactor Cp in order to pack waste such as garbage into the container Ct by the compactor Cp, the container
The locking levers 46 and 49 of the upper and lower locking devices Lu and Ll provided on Ct collide with the abutting piece 54 of the lock release member 52 of the compactor Cp, and these locking levers 46 and 49 are arranged as shown in FIG. Both are swung to the unlocked position against the resilient force of lock springs 47, 50.

After the compactor Cp and container Ct are connected together by a conventionally known lashing device (not shown),
When both the upper and lower bar-tacking members 31 and 30 are removed, the main gate Gm and the sub-gate Gs are separated from the entrance/exit 28 of the container Ct, and at the same time, the main gate Gm is attached to the pushing surface 6 of the pushing ram 5.
Further, the sub-gates Gs are respectively fixed to storage recesses 19 on the front surface of the elevating plate 15. Thereafter, the elevating cylinder 16 is contracted to raise the elevating plate 15 above the pushing passage to form a sufficient gap between the upper surface of the extrusion port 2 and the pushing ram 5, and by repeatedly moving the pushing ram 5 back and forth. The container Ct is filled with waste.

When the waste is filled in the container Ct, the main gate Gm is positioned at the push-in port 2 so that its insertion hole 36 and the communication hole 35 of the container Ct are aligned (Fig. 3), and the lifting cylinder 16 is opened. The elevating plate 15 is extended and lowered, and the sub-gate Gs fixed to the front side is inserted into the insertion hole 41 and the container Ct.
It is positioned in the push-in port 2 so that the communication hole 40 of After that, the pair of bar-tacking rods 32 and 33 of the lower bar-tacking member 30 on the side of the tailgate 26 closer to the main gate are inserted into the communication holes 35 and 35 and the insertion hole 3.
6 and 36, the bar tacking rod 3
2 and 33 push up the engagement hook 10 (Fig. 3) to release the connection between the pushing ram 5 and the main gate Gm, and at the same time fix the main gate Gm to the tailgate 26. A pair of bar-tacking rods 37 and 38 of the upper bar-tacking member 31 on the side of the gate 26 and closer to the sub-gate are connected to the communication holes 40 and 4.
0 and the insertion holes 41, 41, the bar-tacking rods 37, 38 are inserted into the engagement hook 20 (the third
) can be pushed up to release the connection between the elevating plate 15 and the sub-gate Gs, and at the same time, the sub-gate Gs can be fixed to the tailgate 26.

Next, the lashing device (not shown) is released and the container is secured.
When Ct is advanced away from the compactor Cp, the outer lock levers 46, 49 and 46, 49 of the upper and lower locking devices Lu, Ll are all separated from the abutting piece 54 of the retaining release member 52, and their The lock levers 46, 49 and 46, 49 all lock the bar-tacking members 30, 31 as shown in FIG.
The bar-tacking members 30, 31 are rotated to a position opposite to the end surfaces of the bar-tacking rods 32, 38, that is, to a locked position, thereby preventing the lower and upper bar-tacking members 30, 31 from being pulled out. In this case, a portion of the inner lock lever 46 and the outer lock lever 49 overlap each other and oppose the end surfaces of the bar-tacking rods 32, 38, respectively, so that the bar-tacking members 30, 31 are doubly locked. Therefore, the inner locking mechanism 4
3 and the outer lock mechanism 44 malfunction for some reason, the bar-tacking member 3
The locking action of 0.31 is ensured.

C. Effects of the invention As described above, according to the invention, the container is provided with lower and upper bar-tacking members for bar-tacking the main gate and sub-gate that shield the entrance/exit of the tailgate of the container to the tailgate. The lower and upper locking devices can securely lock the container so that it does not slip out, so even if the container shakes or vibrates when it is loaded onto a transport vehicle, etc. Both the main gate and the sub-gate can be reliably fixed to the tailgate without the members accidentally slipping out, and the stability of the container during transportation can be greatly improved.

Also, when connecting a container to a compactor,
The locking states of the lower and upper locking devices are automatically released by the engagement of the abutment member provided on the compactor with the lower and upper locking devices, thereby easily and easily removing the lower and upper bar-tacking rods. can significantly improve work efficiency.

As shown in the above embodiment, by providing the lower and upper locking devices with an inner locking mechanism and an outer locking mechanism, it is possible to double lock the lower and upper barlock bars, further improving stability.
