Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage truck that sorts and collects garbage packaging containers discharged from stores such as convenience stores, supermarkets and hotels.

[0002]

2. Description of the Related Art In recent years, environmental awareness such as recycling and clean energy has been increasing. For example, foods, packaging containers, disposable chopsticks, etc. to be disposed of at convenience stores, supermarkets, hotels, etc. Regarding `` packaging containers ''), there is a problem that if they are incinerated as they are, harmful substances such as dioxins will be generated from the packaging containers, and that the moisture in the garbage will reduce the combustion efficiency of the incinerator. When used as livestock feed, there is a problem that livestock is injured by mixed chopsticks and toothpicks.

[0003] Therefore, after separating the packaging container containing the garbage into the garbage and the packaging garbage, the garbage is not incinerated but used, for example, as a feed for livestock, or biogas produced by fermentation decomposition. It is used to generate electricity. Various proposals have been made for a device for separately collecting and collecting the packaging container containing food waste into the garbage and the packaging container waste, a device for recycling the garbage without incineration, and the like.

For example, in Japanese Unexamined Patent Publication No. 11-333315, a half-drum body is provided in a case provided with a charging port, a rotary shaft having rotary blades is provided in the drum body, and packed food is packaged. And an automatic separating and crushing device that separates the packaging material and the waste food that have been separated into waste food.

Further, Japanese Unexamined Patent Publication No. 8-12005 discloses that
There is described a waste disassembling vehicle in which a garbage truck is equipped with a food waste disposer, and the garbage is fermented and decomposed by microorganisms while the vehicle is running, and the garbage is recycled without incineration. Further, in Japanese Unexamined Patent Publication No. 2000-289805, a garbage transporting device that conveys garbage to the upper part of the vehicle, a packaging material crushing device that crushes the packaging material of the transported garbage, and the garbage and the packaging material are separated. There is described a garbage recycling vehicle provided with a packaging material sorting device and a garbage decomposing device that decomposes and treats garbage separated by a microorganism while the vehicle is running.

Further, as shown in FIG.
The packaging material sorting vehicle 100 for packaged food described in Japanese Patent Publication No. 01-130707 has an insertion port 1 provided on a side surface of a vehicle body.
When the packaged food is put into 01, the packaged food is conveyed to the inside of the input hopper 103 by the conveying means 102 and is put into the inside of the sorting chamber 104. Then, in the sorting chamber 104, the packed food is sorted into raw garbage and packaging material, and the raw garbage is collected in the lower garbage collection chamber 105 and the packaging material in the rear packaging material collection chamber 106. . Then, when the separately collected food waste and the packaging material are discharged to the outside, as shown in FIGS. 7B and 7C, the garbage collection chamber 105 or the packaging material collection chamber 106 is moved to the right of the vehicle. By rotating it by a predetermined angle to the garbage discharge door 107 or the discharge door 1
This is done by opening 08.

[0007]

However, the automatic separating and crushing device described in Japanese Patent Laid-Open No. 11-333315 is stationary, that is, it is costly because it needs to be installed in each store such as a convenience store. However, there is a problem that it takes time for safety management and hygiene management. Further, the waste decomposition vehicle described in JP-A-8-12005 is for fermenting and decomposing raw garbage to recycle it, and separates the packaging container containing the garbage into the garbage and the packaging container garbage. There is a problem that you cannot do it. Further, since the food waste recycling vehicle described in JP 2000-289805 A is configured to be equipped with many devices such as a food waste conveying device, a packaging material crushing device, a packaging material separating device, and a food waste disassembling device, The cost of the vehicle will increase, and as the weight of the vehicle increases, the load of raw garbage and packaging materials will decrease and the stability of the vehicle will deteriorate.Furthermore, each of these devices will have a complicated configuration as a whole and maintainability will deteriorate. There is a problem of doing.

Further, in the packaging material sorting vehicle 100 for packaged food described in JP 2001-130707 A, since the sorting chamber 104 is provided above the garbage collecting chamber 105, the capacity of the garbage collecting chamber 105 is small. Moreover, since the food waste that has fallen inside the food waste collection chamber 105 is conveyed as it is, there is a problem that the internal space of the food waste collection chamber 105 cannot be used efficiently. Further, since the raw garbage or the packaging material is discharged to the outside by rotating the raw garbage collecting chamber 105 or the packaging material collecting chamber 106 by a predetermined angle to the right of the vehicle, for example, when the raw garbage having high adhesiveness is discharged. Requires a large rotation of the garbage collection chamber 105 and the packaging material collection chamber 106, and there is also a problem that it is difficult to ensure the stability of the vehicle.

According to the garbage truck 4 of the present embodiment, since the dust discharging device 80 is roughly constituted by the dust pushing plate 81 and the pushing cylinder 82, the structure of the dust discharging device 80 becomes relatively simple. The manufacturing cost of the dust discharge device 80 can be reduced and the reliability can be improved.

Since the dust separating device 70 and the dust discharging device 80 are arranged in the left-right direction, a large space is formed behind the dust separating device 70 and the dust discharging device 80.
Therefore, the worker uses this space to collect the dust separating device 70.
Further, the maintenance of the dust discharge device 80 can be easily performed, and the dust input port 71 and the packaging container dust outlet 7 can be easily used.
2. A space for disposing the container receiver 73 and the like can be secured. Furthermore, since the installation space for the dust separating device 70 and the dust sending device 80 is short in the front-rear direction, the dust separating device 70 and the dust sending device 80 can be installed even in a vehicle with a relatively short wheelbase.

When the garbage is discharged to the outside of the vehicle,
The discharge opening portion 32 is rotated rearward and upward, and the dust discharge device 8
By moving the 0 waste pushing plate 81 forward, it is possible to discharge the raw garbage remaining in the waste discharging device 80 to the outside of the vehicle, so that the cleaning work of the waste discharging device 80 after the waste collecting work is completed. Can be simplified.

In each of the first and second embodiments, the dust separator 10 having the stirring blade has been described. However, the dust separator 10 is not limited to this and is generally used. If it is good. In addition, although the one using the screw feeder 21 and the one using the dust pushing plate 81 have been described as the dust sending devices 20 and 80,
Any structure may be used as long as the garbage can be sent forward. In addition, the hinge portion 33 is provided to provide the discharge opening portion 32.
Although the one configured to rotate is shown, the discharge opening portion 3
It goes without saying that any structure may be used as long as the second container moves to open the rear of the waste container box body 31.

In each of the first and second embodiments, the discharge plate 41 is moved rearward by the extension of the discharge cylinder 42. However, what kind of mechanism is used to move the discharge plate 41? It may be. Similarly, in each of the first and second embodiments, the discharge opening portion 32 is rotated by the extension of the opening cylinder 34, but what kind of mechanism is used to rotate the discharge opening portion 32? May be. Further, in the second embodiment, the dust pushing plate 81 is moved forward by extension of the pushing cylinder 82, but any mechanism may be used to move the dust pushing plate 81. .

The shape of the step member 60 and the arrangement position of the packaging container dust container 50 in each of the first and second embodiments are also arbitrary, and other specific detailed structures can be appropriately changed. Of course there is.
