The refuse collection vehicle according to the present embodiment has the above-described configuration. Hereinafter, a method of using the refuse collection vehicle according to the present embodiment will be described.

First, when collecting garbage, the side plate 1
5 and 15, the pin 11b is immersed in the crusher side table 11 by the handle 11c of the crusher side table 11, the crusher side table 11 is rotated to a horizontal state, and the pin 11b is
It is engaged in 15 holes 15a.

The worker discriminates the garbage to be collected into garbage that does not need to be crushed and garbage that needs to be crushed. When collecting garbage that does not need to be crushed,
The door 4a is opened, and refuse is introduced through the upper refuse input port 4. The dust input from the upper dust input port 3 falls into the tail gate 2, is scraped up by the rotating plate 22, and is sent into the dust storage box 1 by the pushing plate 21.

When collecting dust that needs to be crushed, the door 4a of the upper dust input port 4 is closed,
The loading table 12 is tilted horizontally with respect to the crusher-side table 11, the stopper piece 12a is inserted through the hole 11a, and the dust input port 3 is opened as shown in FIG. The garbage is placed on the garbage loading table 10 and pushed into the crusher 6 side.

The pushed dust is crushed by the crusher 6 and falls into the tailgate 2, and is scraped up by the rotating plate 22 in the same manner as dust thrown in from the upper dust inlet 4, and is pushed in. It is sent to the garbage storage box 1 by 21.

When the collecting operation is completed, the stopper piece 12a is detached from the hole 11a, the mounting table 12 is folded toward the crusher table 11, and the garbage loading table 10 is erected. 15 to close the refuse input port 3 and move the traveling vehicle D to a destination such as a garbage disposal site.

After reaching the destination, the opening and closing cylinders 9, 9
Then, the opening 1a of the dust storage box 1 is opened, and the dump cylinder D2 is extended, as shown in FIG.

The garbage collection vehicle of this embodiment is used as described above. At the time of garbage collection, the garbage storage box 1 is connected to the dust collection device 8 at the upper front, so that the garbage input ports 3 and 3 can be used. Four
Therefore, there is an advantage that the dust can not be scattered, and the work can be performed smoothly without the worker being bothered by the dust.

When a worker puts dust into the dust inlet 3 on the lower side, the dust can be placed on the loading table 10 and pushed into the crusher 6. Can easily push the trash into the crusher 6.

Furthermore, even if an operator pushes dust into the crusher 6 side, the mounting table 10 for dust input is configured so that a human hand does not reach the crusher 6, so that the human hand is crushed by mistake. Never touch machine 6.

Further, since the crushing blades 16a and 16b are arranged side by side to face the refuse input port 3 and mesh with each other, the crushing blades 16a and 16b
Since the refuse existing near 16b is caught and drawn into the crusher 6, the crushing operation can be easily performed.

Furthermore, since the entire mounting table 10 is rotatable about the pivot shaft 3b on which the crusher table 11 is pivotally mounted, the crushing blades 16a and 16b do not sufficiently bite the trash. In addition, the dust can be bitten by the crushing blades 16a and 16b by tilting the mounting table 10 for dust input. In particular, the side plate 15 is provided with four holes 15a, into which the pins 11b can be inserted, so that the pins 11b can be inserted into the desired holes 15a to tilt the garbage loading table 10. It has the advantage that it can be kept.

Further, when the crusher 6 is crushing garbage, the sheet 15 is hung down at the garbage input port 3, so that
There is an advantage that scattering of dust generated by the crusher 6 can be prevented.

Further, when the crusher 6 is used, the upper dust input port 4 is closed by the door body 4a, so that scattering of dust from the upper dust input port 4 can be prevented.

When the placing table 12 is not level with the crusher table 11 by the limit switch 14, the driving of the crushing hydraulic motor 18 is stopped. The crushing machine 6 is not driven when the crushing machine side table 11 is folded, etc., and the crushing machine 6 is driven only when the crushing machine side table 11 is opened horizontally and human hands cannot reach the crushing machine 6. Therefore, a human hand does not accidentally touch the crusher 6 being driven.

Further, a hydraulic circuit for operating the crushing hydraulic motor 18 is provided separately from the hydraulic circuit such as the pushing device 5 and the crushing hydraulic pump of the hydraulic circuit is of a variable displacement type. Even if the discharge pressure and the flow rate are changed by the load applied to the crusher 6, crushing suited to the properties of the dust can be reliably and easily performed without changing the rotation speed of the car engine. In addition, since the required horsepower of the crushing hydraulic pump is constant, there is an advantage that the load on the vehicle engine is constant and the operation of other hydraulic pumps connected to the same engine is not affected.

Further, even large-sized refuse can be crushed by the crusher 6 and sent to the refuse storage box 1 by the rotating plate 22 and the pushing plate 21, so that the size of the rotating plate 22 and the pushing plate 21 can be reduced. Regardless, garbage can be sent in accurately, and garbage collection work can be performed smoothly.

In each circumferential groove 26a,. By doing so, the number of times of crushing per rotation of the crushing rotor 26 can be increased. Thus, each circumferential groove 26a,.
Even if a plurality of crushing blades 28, ... are provided, the rotation locus is the same,
The crushing frequency per rotation of the crushing rotor 26 can be increased while the same fixed blade 27 is used.

<Other Embodiments> Although the first embodiment and the second embodiment have the above-described structure and have the above advantages, the refuse collection vehicle according to the present invention is not limited to these. A crusher 6 is provided in the vicinity of the opening 3, and the crushed crusher 6 pushes the trash into a trash storage box.
The design can be changed as appropriate as long as it has a configuration that feeds into 1.

That is, in any of the above-described embodiments, the dust collecting vehicle provided with the pushing device 5 composed of the pushing plate 21 and the rotating plate 22 has been described, but the pushing plate 21 for feeding the dust into the dust box 1 is described. The present invention can be appropriately changed in design as long as it is a refuse collection vehicle provided with the pushing device 5 provided with the rotary plate 22, and the rotating plate 22 is not an essential requirement. For example, as shown in FIGS. 10 and 11, the movable plate 40 in the tailgate 2 is formed to move along the guide rail 41 by a vertically moving cylinder 43 fixed to the frame 2a of the tailgate 2, This is a dust collecting vehicle equipped with a pushing device 5 in which a pushing plate 21 pivotally attached to the movable plate 40 is rotatably provided by expansion and contraction of a rotating cylinder 44. As shown in FIG. The movable plate 40 is lowered by the contraction of 43, the pushing plate 21 pivotally attached to the movable plate 40 is turned forward by the extension of the rotating cylinder 44, and the dust crushed by the crusher 6 is scraped up. Next, even if the pushing plate 21 is moved upward by the extension of the vertical moving cylinder 43 to feed the trash into the trash storage box 1, it also belongs to the scope of the present invention.

In the first embodiment, a biaxial crusher 6 is used. In the second embodiment, a crusher 6 having a crushing blade 28 and a fixed blade 27 is used. However, the type of crusher 6 used in the present invention is not limited, and for example, the scope of the present invention is not limited to a triaxial crusher, etc. It belongs to

Further, even when the two-shaft crusher 6 is used as in the first embodiment, the specific configuration is not limited to that of the first embodiment.

In particular, in the above embodiment, the two crushing shafts 17a and 17b rotate at the same rotation speed.
It may be one that rotates at a different number of revolutions, so that even for thin sheet-like dust, there is no inconvenience that the dust is not sufficiently crushed and is sent between the crushing blades 16a and 16b,
Crushing can be performed accurately.

Further, when collecting various kinds of dust, the rotation ratio between the crushing shafts 17a and 17b may be formed so as to be changeable, so that the rotation ratio can be changed according to the properties of the dust. It is possible to crush garbage accurately. For example, as shown in FIG. 12, the ends of two crushing shafts 17a and 17b are inserted into the gear box 20, and one of the crushing shafts 17b is fixed with large and small gears 20c and 20d, and the other crushing shaft is fixed. A large and small integrated gear 20a, 20b capable of meshing with the gears 20c, 20d is slidably mounted on 17a, and a handle 20e for sliding the gears 20a, 20b in the axial direction and sliding means of a lever 20f are provided. The gears 20a and 20b are slid by the handle 20e via the lever 20f to engage the gear 20a and the gear 20d as shown by the solid line in FIG. 12 (a), or to engage the gear 20b as shown by the broken line in FIG. 12 (a). The gear ratio between the crushing shafts 17a and 17b can be adjusted in two stages by meshing the gears 20c with each other or changing the meshing between the gears 20a. Here, the sliding means does not need to be composed of the handle 20e and the lever 20f, but may be a means for sliding the gears 20a and 20b by electric or hydraulic pressure. Further, each of the crushing shafts 17a, 17b may be connected to a separate crushing hydraulic motor so that the rotation ratio of the crushing shafts 17a, 17b can be changed. Because the rotation ratio can be adjusted at other stages,
Crushing according to the properties of the garbage can be performed more reliably.

Further, in the first embodiment and the second embodiment, the refuse collection vehicle provided with one crusher 6 has been described. However, the present invention is not limited to these. Two or more crushers 6 may be provided for the trash input port 3. For example, a crusher 6 for crushing garbage roughly may be provided on the side of the trash input port 3 and a crusher 6 for continuously crushing finely, so that garbage can be crushed more finely.

[0080]

As described above, in the refuse collection vehicle according to the present invention, a crusher is provided on the trash input port side of the pushing device, and the crushed crusher sends the trash crushed into the trash storage box. Therefore, even if the garbage has a certain form, such as wood or plastic products, the garbage can be stored in a tighter state than the conventional garbage trucks. This has the effect that the capacity can be fully exhibited.

Further, since the pushing plate feeds the dust crushed by the crusher, the mechanical strength of the pushing plate can be reduced as compared with the conventional one, so that the pushing device can be downsized.

Further, even when the garbage collected by the garbage collection vehicle according to the present invention is landfilled or recycled, it is not necessary to use a crusher or the like at a disposal site or a factory. For this reason, much labor and equipment can be made unnecessary in the treatment process, and the effect of increasing the efficiency of the treatment of collected dust can also be obtained.

Further, installing a two-shaft crusher
Therefore, when crushing the garbage input from the garbage input port , the garbage can be crushed smoothly by the biaxial crushing blade rotated by the two crushing shafts, so that the garbage collection work can be performed more smoothly. Is possible , and various garbage can be removed.
When collecting, use a crushing shaft according to the nature of the garbage.
By changing the rotation ratio of each other, it is possible to crush garbage accurately
It is possible.

[0084] Also, as in claim 2, wherein, by mounting the crusher to perform the crushing by the crushing blade and the fixed blade attached to the crushing rotor, replacement of the crushing rotor itself or crushed mounted on the crushing rotor By replacing the blade, the number of crushing operations per rotation of the crushing rotor can be increased or decreased.According to the type of garbage to be collected, garbage collection can be performed quickly and accurately, and each circumferential groove is Multiple breaks
The same fixed blade is used because the rotation locus is the same even if a crushing blade is provided
The number of crushes per rotation of the crusher rotor
You can do it.

Furthermore, if two or more dust inlets are formed in the tailgate and a crusher is provided near at least one dust inlet, the operator can determine the type of dust. By selecting the garbage input port to put in, the crusher is not overly burdened,
In addition, there is also an effect that the collection operation can be performed quickly by selecting the refuse input port that matches the property of the refuse.
