Description

[Detailed Description of the Invention] This invention relates to a sewage treatment device for a garbage collection vehicle that prevents sewage discharged from garbage stored in a garbage storage box from leaking to the outside.

In a garbage collection vehicle that has a garbage storage box and a garbage input box that is rotatably supported above the rear of the garbage storage box and closes the rear opening of the garbage storage box, water is present in the garbage and the input box is closed. Since the garbage thrown into the storage box is compressed and pushed into the storage box by the pushing device, sewage comes out from the stored garbage.

The sewage leaks out from the joint between the rear opening of the storage box and the front opening of the input box, and the sewage is scattered on the road surface, causing a foul odor and staining the garbage collection vehicle.

Conventionally, therefore, an elastic sealing material is interposed at the lower part of the joint between the rear opening of the storage box and the front opening of the input box, and both boxes are tightened by a tightening device to maintain the watertightness of the joint.

In addition, a sewage receiver is provided on the bottom of the garbage disposal box near the joint to allow sewage from inside the storage box to flow into it.

However, the tightening device between the storage box and the input box is disassembled and the garbage is discharged outside from the rear opening of the storage box, but when the joint is opened, the sewage that has been stored by the elastic sealing material is sprayed out all at once. They cause damage to workers and pollute the surrounding area, seriously impairing environmental hygiene.

Further, if dust adheres to the joint, when both boxes are closed, the adhered dust abnormally deforms the elastic sealing material, and sewage leaks out from there.

Furthermore, since the upper joint of the sewage receptacle is sometimes blocked by debris, sewage does not flow into the sewage receptacle, and the sewage flows out along the joint.

In order to prevent these, conventionally,
As seen in the publication, a waste water receiver is provided along the bottom of the joint between the garbage storage box and the waste input box, a drain port is provided at the bottom of this waste water receiver, and one end of the drain pipe is connected to this drain port. However, it has been proposed to connect the other end of this drain pipe to a sewage tank installed at the bottom of the garbage disposal box, but this requires a separate sewage receiver and also requires the use of a drain pipe. Therefore, there is a drawback that this drain pipe is easily damaged or clogged.

Therefore, in this invention, instead of installing a sewage receiver, an elastic sealing material is provided at the joint to create a sewage receiver, and instead of providing a drain pipe, the inside of the garbage disposal box is used as a conduit to the sewage receiving tank. A sewage introduction hole communicating with the input box is provided directly above the elastic sealing material so that the sewage can be stored in a sewage receiving tank provided at the bottom of the garbage input box without leaking to the outside.

Hereinafter, this invention will be described in detail based on embodiments shown in the accompanying drawings.

The garbage collection vehicle has a subframe 2 placed on a frame 1 that extends back and forth, and a garbage storage box 3 which is pivotally connected to the lower rear end of the subframe 2 so as to be dumpable. A garbage disposal box 5 is provided to close the rear opening 4 of the container.

A garbage pushing plate 6 is housed in the input box 5, and its central portion is rotatably pivoted, and its upper end is connected to the tip of a piston rod of a drive cylinder 7 whose base end is pivoted to the upper inner wall of the rear end of the storage box 3. do.

As the driving cylinder 7 expands and contracts, the pushing plate 6 rotates back and forth to send the garbage into the storage box 3 and compress it.

On the other hand, the rotary plate 8 is located below the push plate 6 in the input box 5 and is pivoted at its base end, and the push plate 6 collects the garbage thrown in from the garbage input port 9 opened at the rear of the input box 5. Rotate so that pushing is possible.

To discharge garbage from the garbage collection vehicle, the input box 5 is opened as shown by the two-dot chain line in FIG. 1, and then the storage box 3 is dumped.

A frame material 1 is installed in the left and right direction at the lower part of the periphery of the rear opening 4 of the storage box 3.
0 is arranged, and the bottom plate 11 of the storage box 3 is provided in a planar shape facing forward on the upper surface of the frame member 10.

On the other hand, a plywood plate 12 is provided at the front lower part of the input box 5, facing the frame material 10, and lifts both ends slightly upward so as to abut the rear surface of the frame material 10, and makes the center horizontal. The elastic sealing material 13 is attached to the plywood 1 via the U-shaped holding fitting 14.
Attached to 2.

Note that a gutter member 15 is arranged horizontally below the elastic sealing material 13 and fixed to the plywood 12 in case of an emergency.

Therefore, in the unlikely event that the elastic sealing material 13 cannot maintain the watertightness of the sewage and the sewage flows out, it will be captured by the gutter member 15 and
A sewage introduction hole 16 is provided in the wall of the input box 5 to communicate the bottom of the input box 5 with the inside of the input box 5, and the sewage is introduced into the input box 5 and stored in a sewage receiving tank 17 on the bottom of the input box 5.

In addition, a waste water introduction hole 18 is provided in the wall of the charging box directly above the elastic sealing material 13 to communicate with the inside of the charging box 5.
The wastewater stored above is guided into the input box 5 into the wastewater receiving tank 1
7 is stored.

Next, a tightening device for the storage box 3 and the input box 5 will be described.

A hook 20 is fixed to the tip of the shaft 19 that protrudes laterally from the subframe 2, and the piston rond tip of the cylinder 21 whose base end is pivotally connected to the subframe 2 and the shaft 1
9, and the hook 20 can be rotated by the expansion and contraction operation of the cylinder 21.

A bracket 22 is fixed to the abutment plate 12 of the input box 5, and a U-shaped engagement IE is provided on the tip surface at a position where it engages with the hook 20.
The material 23 is provided so as to be adjustable.

The cylinder 21 is extended, the hook 20 is engaged with the locking member 23, the storage box 3 and the input box 5 are tightened, the cylinder 21 is retracted, the hook 20 is released from the locking member 23, and the storage box is closed. 3 and the input box 5 are separated.

The elastic sealing material 13 serves as a sewage receptacle for the sewage flowing out from the storage box 3, and the sewage collected here flows through the sewage introduction hole 18, enters the input box 5, and is stored in the sewage receiving tank 17.
The sewage that cannot be kept watertight enough by the elastic sealing material 13 and flows downward is captured by the gutter member 15 and sent to the sewage receiving tank 17.
guided by.

Thus, the wastewater introduced into the charging box flows down along the inner wall of the charging box.

This invention provides a wastewater receiving tank in a garbage collection vehicle that has a garbage storage box and a garbage input box that is rotatably supported above the rear of the garbage storage box and closes the rear opening of the garbage storage box. is attached to the bottom of the garbage disposal box so as to communicate with the interior of the disposal box, and an elastic sealing material is attached at the position of the plywood plate of the garbage disposal box opposite to the peripheral lower frame material of the rear opening of the garbage disposal box, and an elastic sealing material is attached directly above this elastic sealing material. A sewage inlet hole that communicates with the inside of the garbage disposal box is installed so that the flowing sewage flows down the inside wall of the garbage disposal box and into the sewage receiving tank, so there is no need for a separate sewage receiver, and there is no need to install a drain pipe, etc. Since the elastic sealing material is used as a sewage receptacle and the inside of the garbage disposal box is used as a sewage conduit, the structure is extremely simple, and there is no drain pipe exposed to the outside, so this damage can be avoided. There is no need to worry about blockages.
