Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a refuse collection vehicle that dumps a refuse storage box onto a vehicle body to discharge the dust, and particularly to smoothly discharge the dust with a small dump amount. The present invention relates to the structure for discharging dust particles.

[Conventional technology and its problems]

Conventionally, as a garbage truck, as shown in FIG.
A dust storage box 2 is attached to the rear part of the dust storage box 2 so that it can be dumped, and a tailgate 3 that closes the opening 2'of the dust storage box 2 is attached to the tailgate 3 so as to be openable and closable.
It is known that a dust loading device 6 composed of a rotating plate 4 and a pushing plate 5 is provided inside and the dust loaded from the inlet of the tailgate 3 is pushed into the dust storage box 2 while being compressed by the loading device 6. Has been.

In the dust collecting vehicle having the above structure, when the dust storage box 2 is filled with dust, the tailgate 3 is rotated upward to open the rear end opening 2'of the dust storage box 2 and the dust storage box 2 Is dumped onto the car body and the dust inside it is discharged.

However, in such a dump discharge type garbage collection vehicle, when the dust is strongly compressed and pushed into the dust storage box 2 or when the dust has a high viscosity and easily adheres to the inner wall of the dust storage box 2, the dust is collected. A dust bridging phenomenon may occur in the storage box 2, and it may be difficult to discharge the dust only by dumping the dust storage box 2 at a normally set angle (about 45 degrees).

In this case, the operator uses a scraping rod or the like to remove the dust container 2
It is necessary to scrape out the dust inside, which is a troublesome work.

Further, in the dust collecting vehicle having the above structure, since the dust loading device 6 is provided in the tailgate 3 and a large weight is present at the rear end of the dust storing box 2, the dust storing box 2 is dumped rapidly. Then, due to the imbalance of weight, there is a possibility that the garbage truck may overturn to the rear.

On the other hand, as a conventionally known dust collecting vehicle, as shown in FIG. 4, a shield plate 21 is movably attached to guide rails 20 provided on both side walls of the tailgate 3 and the shield plate 2 is provided.
1. A reversing plate 22 is attached to the lower end of 1, and a dust loading device 19 having an arc surface 23 along the rotation trajectory of the reversing plate 22 is provided on the bottom wall of the tailgate 3 and moved back and forth inside the dust storage box 2. Some of them are provided with a push-out plate 24 and a drive cylinder 25 which are possible.

In the dust collecting vehicle of this structure, the dust thrown in through the inlet of the tailgate 3 is crushed between the reversing plate 22 and the arc surface 23 and pushed into the dust storage box 2, so that only the soft dust such as raw dust is Not only that, there is an advantage that even solid materials such as bicycles and refrigerators can be compressed and stored. Further, the dust is discharged by operating the drive cylinder 25 while moving the dust container box 2 horizontally and moving the push-out plate 24 rearward to push out the dust from the rear end opening of the container box 2.

However, in the dust collecting vehicle as described above, since the push-out plate 24 and the drive cylinder 25 are attached, the structure of the dust storage box 2 becomes complicated and the manufacturing cost becomes high. Since the opening is open, there is a problem that the bad odor of dust and sewage leak to the outside from the opening 26 and obstruct the environment.

For this reason, it has long been desired to apply a dump system using a dust storage box having a closed structure and a simple structure to the dust collection vehicle, but as described above, the tailgate 3 is used.
The structure in which the shield plate 21 and the reversing plate 22 are provided inside generally has a larger weight in the rear portion of the dust storage box 2 than that provided with the dust loading device 6 shown in FIG. There is a drawback that a car overturn accident is likely to occur.

The present invention has been made in view of the above problems, and has a structure in which a dust container is dumped onto a vehicle body to discharge dust, and by adding a simple concept, dust can be smoothly discharged with a small dump amount. It is an object of the present invention to provide a garbage collection vehicle that can be discharged to the inside.

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides a plurality of ridges extending from the front end to the rear end of the dust storage box on the inner wall surface of the dust storage box, and these ridges are provided in the dust storage box. The structure was set to a size that forms a gap between the contained dust and the inner wall surface.

In the above means, the ridge may be a ridge that is inclined in the front-rear direction so as to decrease toward the rear end.

[Action]

In the above structure, the ridges provided on the inner wall surface cause a gap between the inner wall surface and the dust, and the frictional force between the two becomes smaller in the front and rear of the dust storage box, so the dust dumps the storage box a little. The pressure on the wall surface is easily released just by letting it discharge smoothly.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the dust collecting vehicle of the embodiment mounts a dust storage box 2 on a rear portion of a vehicle body 1 via a shaft 7 so that the dust storage box 2 can be dumped, and a tailgate 3 is attached to a rear end of the dust storage box 2. The hinge pin 8 is attached so that it can swing back and forth,
The tailgate 3 is provided with a dust loading device 6 including a rotating plate 4 and a pushing plate 5. The tailgate 3 is an opening / closing cylinder 9 provided between both side surfaces of the tailgate 3 and the dust storage box 2.
It is opened and closed by.

The dust storage box 2 is formed in a box shape in which the front surface is closed and the rear surface is opened, and the front opening of the tailgate 3 faces the opening of the rear end.

In addition, on the inner wall surface of the dust storage box 2, as shown in FIGS.
13 are provided. The ridges 11, 12, 13 are formed in a triangular cross section, and the ridges 1 provided on the bottom plate 2a
1 is formed in an inclined shape so that the height gradually decreases from the front end to the rear end. In addition, each ridge 11, 12,
The size of 13 is set to such a size that when dust is stored inside the dust storage box 2, a gap is formed between the dust and the inner wall surface of the dust storage box 2. Further, the surface of each of the ridges 11, 12, 13 is coated with a lubricating resin layer 14 of fluororesin, polyamide, polyethylene or the like to reduce the slip resistance of the surface.

In the above structure, a gap is formed between the dust and the inner wall surface of the dust storage box 2 due to the ridges 11, 12, and 13, and the crimped state of the two is relaxed in the front-back direction of the storage box 2 to store the dust. Box 2 dumps a little, and ridges 11,
It slides along 12 and 13 and is smoothly discharged from the storage box 2.

In this embodiment, as the dust loading device, the rotary plate 4 and the pushing plate 5 are combined, but as shown in FIG. 4, the dust loading device 19 is composed of the shielding plate 21 and the reversing plate 22. The present invention can also be applied to. That is, since the structure of the present invention can discharge dust with a very small amount of dump, even if there is a heavy dust loading device 19 at the rear of the dust storage box 2, it is possible to prevent a capsizing accident to the rear. As a result, it is possible to provide an ideal dust collection vehicle that combines a dump discharge type dust collection box with a simple structure and a dust loading device that can collect any dust regardless of raw garbage or solid matter. it can.

[Effect of device]

As described above, in the present invention, the protrusions are provided on the inner wall surface of the dust container to reduce the frictional force acting between the inner wall surface and the dust, so that the dust inside the container can be smoothly removed with a small dump amount. Can be discharged to. Therefore, there is an effect that the operation of discharging the dust can be facilitated and an accident in which the dust truck is overturned backward can be prevented.
