Description of the Related Art A conventional garbage truck collects garbage discharged from households and offices, mainly garbage stored in garbage bags, by a garbage truck operating on a predetermined course. I have to. In addition, simply collecting garbage by operating garbage trucks limits the amount of garbage collected at one time, and requires garbage trucks to be dispatched many times. To improve this, increase the amount of garbage collected at one time, and increase the garbage collection capacity, garbage collection vehicles are provided with a compression function to compress and collect garbage. In addition, any of the refuse collection vehicles discharges into a garbage pit at a designated garbage incineration site or a garbage disposal site and incinerates and disposes of it.

[0003]

However, conventional refuse collection vehicles have only a function of collecting garbage, and in particular, household refuse in a garbage bag is separated for refuse after discharge. Garbage bags should be broken manually, or the collected garbage bags should be thrown into a dedicated device for crushing the bags. There was no.

[0004] Accordingly, labor is required in the work of breaking the garbage bags, a separate bag breaking device is required, a dedicated bag breaking device is provided in the pit of the garbage incineration plant, and the garbage crane is agitated. There was a problem that necessary work was required. Also, without breaking the bag enough,
If the garbage stored in the bag is incinerated at the garbage incineration plant, the garbage will not be sufficiently agitated and the quality of the garbage will be uneven, or the moisture enclosed in the garbage bag together with the garbage will be removed. Since it is incinerated as it is, there is a problem that the incineration temperature of the refuse in the incinerator fluctuates, and harmful substances such as dioxin are easily generated.

The present invention has been made in view of the above-mentioned various problems in the conventional refuse treatment, and by reliably breaking the garbage bag during refuse collection, it is possible to suppress the generation of toxic dioxins and the like, thereby achieving an overall refuse treatment system. Lower cost in the process,
It is an object of the present invention to provide a garbage truck that can save labor and energy.

[0006]

In order to achieve the above object, a refuse collection vehicle according to the present invention includes a garbage collection vehicle having a function for temporarily storing and discharging garbage collected while moving, and A bag breaking device for breaking the waste bag is provided adjacent to the waste storage unit.

This garbage collection vehicle can surely break the garbage bag at the time of garbage collection, so that the garbage can be sufficiently stirred and homogenized. Water contained can be reliably separated, the temperature during incineration can be easily maintained at a constant high temperature, and the generation of toxic dioxins and the like can be suppressed. In this case, the garbage bag can be broken when it is put into the garbage truck and / or when it is discharged.

In this case, the bag breaking device can be constituted by a swing arm having a plurality of projections for breaking the garbage bag.

Thus, when the garbage bag is discharged, the bag can be reliably broken with a simple structure only by swinging the swing arm.

[0010] In this case, the bag breaking device can be constituted by a turntable having a plurality of projections for breaking the garbage bag.

As a result, the garbage bag put into or discharged from the garbage collection vehicle is torn by the rotating bag-breaking projection, and is reliably broken.

In this case, a deodorizing device can be provided in the garbage truck.

[0013] Accordingly, the odor generated from the refuse collected in the refuse collection vehicle is suppressed, and the odor is not leaked outside, so that the working environment can be improved.

[0014] In this case, a waste water receiving tank can be provided in the refuse collection vehicle.

[0015] Thus, the moisture from the broken garbage bag can be collected before the incineration of the garbage, so that the moisture of the garbage can be easily adjusted, and the generation of harmful dioxins and the like can be suppressed by a simple method. .

Then, the garbage bags 10 collected by hand or the like are thrown into the opening portion and the turntable 6 which is temporarily fixed at the illustrated position, and the turntable 6 is turned to remove the garbage bags 10 on the turntable 6. It is stored in the inner part of the storage unit 2. Reference numeral 11 denotes bag-breaking garbage already stored in the garbage truck.

In this way, the collected garbage bags are stored between the turntable 6 and the opening, and when this portion is filled with the collected garbage bags, as shown in FIG. The guide plate 5 is turned rightward around the center 61, and when the guide plate 5 reaches the position shown in the figure, the guide plate 5 is turned next. This guide plate 5
However, when the rotating disk 6 rotates about the pivot 51 as shown in FIG. 3, the rotating disk 6 further rotates to the illustrated position. The guide plate 5 and the turntable 6 alternately perform a series of rotating operations in this manner, so that the thrown refuse bag enters the refuse storage unit 2 and becomes stored refuse. Next, when a garbage bag is to be inserted, the guide plate 5 rotates again to the position shown in FIG. 1, and the above operations are sequentially repeated to collect garbage until the garbage storage unit 2 becomes full.

Next, a case of discharging the garbage bag 10 stored in the garbage storage section 2 will be described with reference to FIG. When the garbage bag 10 is discharged, the discharge plate 7 located inside the garbage storage unit 2 is moved to the right, that is, to the opening side of the garbage storage unit 2, and the garbage bag 10 in the garbage storage unit 2 is moved in the exit direction. And discharge while compressing. At this time, the guide plate 5 is retracted to the illustrated position, and the bag breaking device 4 rotates to the illustrated position about the pivot 41. Therefore, the discharge portion of the garbage bag 10 is sandwiched between the protrusion 40 of the bag breaking device 4 and the turntable 60, and the garbage bag 10 compressed by the discharge plate 7 is sandwiched between the protrusions 40 and 60. The garbage bags are torn out of the garbage truck while being torn. At this time, if the garbage bag is hard or large, the bag breaking device 4 can rotate around the pivot 41, so that the bag breaking operation is stably continued while evacuating as indicated by the broken line in the figure. It is possible to do.

FIG. 5 shows a refuse storage unit 2 serving as a loading platform which can be tilted in the first embodiment, and the refuse storage unit 2 is tilted as shown to be stored in the refuse storage unit 2. At the same time. In this case, since the refuse storage unit 2 can be tilted and disposed on a refuse collection vehicle and tilted to discharge refuse, as shown in the embodiment shown in FIGS. Although the discharge plate 7 is omitted, the other configuration is the same as that of the first embodiment, and the detailed description is omitted. In the case of the second embodiment, the storage garbage bag in the garbage truck falls down naturally because the garbage storage unit 2 is inclined, and the bag is broken by the bag breaking device 4 in the same manner as described above. The garbage bags are discharged outside the collection vehicle, and the action of breaking the garbage bags is the same as in the first embodiment.

FIGS. 6 to 8 show a second embodiment of the garbage truck of the present invention.
An example will be described. The same as in the first embodiment, the refuse collection vehicle 1 is provided with a refuse storage unit 2 and an openable / closable cover 3, and the refuse storage unit 2 is provided with a bag breaking device 4 and a movable discharge plate 7. It is. In the second embodiment, a large number of projections 40 are provided on the peripheral surface of a bag-breaking drum 43 on which the bag-breaking device 4 rotates. A plurality of protrusions 60 are also provided on the bag breaking drum 63, and the two bag breaking drums 4 are disposed so as to face up and down when a garbage bag is charged and discharged.
The bag is broken by controlling the rotation directions of 3, 63. The garbage truck is provided with a deodorizing device 7 and a sewage receiving tank 8 at a lower position of the garbage storage unit 2.
A shielding plate 9 is arranged on the upper part of the bag-breaking drum 43 so that the garbage bag is not unintentionally discharged from the upper part of the bag-breaking device. Reference numeral 80 denotes sewage stored in the sewage receiving tank 8 by collecting and collecting the sewage stored in the bag when the garbage bag is broken.

Next, a refuse collection vehicle 1 according to a second embodiment of the present invention.
Will be described. At the time of refuse collection, the cover 3 is opened by a driving device (not shown), the discharge plate 7 is retracted to the left inside the refuse storage unit, and the bag breaking drum 4 of the bag breaking device 4 is opened.
3 is rotated to the right and the bag-breaking drum 63 is rotated to the left by a driving device (not shown). The bag drum 63 is rotated slowly. In this way, the projections 40 and 60 are driven to rotate so as to provide a difference in the moving speed and the peripheral speed. At this time, the upper part of the bag breaking drum 63,
That is, when the garbage bag 10 is thrown between the bag-breaking drum 43 and the bag-breaking drum 63 of the bag-breaking device 4, the bag is broken by the tearing force due to the speed difference between the projections 40 and 60.
Together with the garbage bags, the garbage is stored in the garbage storage unit 2 as bag breakage refuse 11. At this time, the shielding plate 9 prevents the bag-breaking debris 11 from jumping out of the upper portion of the bag-breaking device 4,
It is securely stored in the garbage storage. The offensive odor from the bag-breaking refuse 11 is deodorized by the deodorizing device 7 and is released to the outside of the storage unit as clean air. In addition, sewage discharged from garbage and the like naturally flows downward and is stored in the sewage receiving tank 8.

Next, the operation of discharging the bag-breaking waste 11 from the waste collection vehicle 1 will be described with reference to FIG. At this time, the bag-breaking drum 43 and the bag-breaking drum 63 of the bag-breaking device 4 are respectively reversed with respect to the dust collection. In addition, the discharge plate 7 moves from the inner part of the refuse storage unit to the right of the opening, moves the refuse 10 in the refuse storage unit 2 toward the outlet, and discharges the refuse while compressing. At this time, if there is a speed difference between the projections 40 and 60, the garbage bags that have not been sufficiently broken at the time of collection can be completely broken. The bag-breaking refuse 11 is released from the garbage truck 1 by the rotation of the bag-breaking drum 63, and is, for example, thrown into a garbage incineration plant (not shown) from a garbage inlet 20 of a garbage incineration plant and finally treated in an incinerator. Is done. The wastewater 80 stored in the wastewater receiving tank 8
Can be processed by removing it from a drain or the like (not shown).

As described above, the garbage bag is broken at the time of storage and temporarily stored in the garbage truck 1, and is further ruptured at the time of discharge, so that the unbagged garbage bag at the time of storage is completely removed. Can be broken. FIG. 8 shows a different method of discharging waste in the second embodiment. This is similar to FIG. 5 in that the waste storage unit is configured to be tiltable, and the waste is naturally tilted downward by tilting the storage unit. It drops and is discharged, and the other configuration is the same as that of the embodiment shown in FIGS. 6 and 7 except that the discharge plate 7 is omitted.

[0026]

According to the garbage truck of the present invention, the garbage bag can be reliably broken at the time of garbage collection.
When the garbage bag is discharged from the garbage truck, the bag is automatically broken by the bag breaking device, so there is no need to manually break the bag in post-processing.In addition, a special bag breaking device is installed at the pit of the waste incineration plant. While eliminating the need for complicated work such as installation and stirring with a garbage crane, the garbage can be sufficiently stirred to homogenize the garbage and reliably separate the water contained in the garbage. The temperature at the time of incineration can be easily maintained at a constant high temperature, and the generation of toxic dioxins and the like can be suppressed. Furthermore, since only a simple device is attached to the refuse collection vehicle, it is possible to reduce the cost, labor and energy in the entire refuse disposal system and process.

Further, when the garbage bag is put into the garbage collection vehicle and / or when the garbage bag is discharged, the bag is broken by the bag breaking drum, so that it is not necessary to break the bag manually.
Further, it is not necessary to provide a dedicated bag breaking device in the pit of the refuse incineration plant, or to perform a troublesome operation such as shaking with a refuse crane.

When a deodorizing device is installed in a garbage truck, a bad odor is generated outside the garbage truck,
Do not leak.

When a sewage receiving tank for storing sewage from garbage is installed, sewage can be naturally moved downward in the garbage collection vehicle. Temperature control can be easily performed.
