Description

[Detailed description of the invention] [Industrial application field] The present invention is a garbage for preventing sewage in a garbage storage box mounted on a garbage collection vehicle from flowing out from the front of the garbage storage box to the outside. The present invention relates to a sewage treatment device for a collection vehicle.

[Conventional technology]

As shown in FIG. 4, the garbage collection vehicle has a garbage storage box 3 mounted on a body frame 2 extending to a lower rear portion of the cab 1,
A tail gate 4 is connected to the rear end opening of the dust storage box 3 and a discharge plate 6 is accommodated inside the dust storage box 3 so as to be movable back and forth. There is one that compresses and discharges the refuse 5 stored in the refuse.

In this type of refuse collection vehicle, the back of the trash storage box 3 is sealed by a tailgate 4, but the front of the trash storage box 3 needs to be opened for cleaning and maintenance of the inside. For this reason, conventionally, a plate-shaped sewage weir 8 is generally arranged at the lower front part of the trash storage box 3 in order to block the sewage 7 collected at the bottom of the trash storage box 3.

In addition, a sewage tank is provided on the bottom of the trash container, and sewage contained in the trash is stored in the sewage tank, and the sewage collected here is discharged to the outside (for example, 55-78605, 59-114
No. 201, etc.).

[Problems to be solved by the invention]

However, in the case of the conventional example shown in FIG. 4 described above, every time the garbage truck stops suddenly, the sewage 7 collected at the bottom of the trash storage box 3 jumps over the sewage weir 8 as shown in FIG. In some cases, the spilled wastewater 7 scatters on the back surface of the cab 1 and contaminates the cab 1 to emit odor and deteriorate the driver's rear view.

Further, even if an attempt is made to provide a sewage tank, not only is it not possible to provide the sewage tank due to space limitations, but if the capacity of the sewage tank is small, the same problem as described above occurs. was there.

In view of the above, the present invention does not provide a sewage tank on the bottom of the trash storage box, etc., and has a relatively simple configuration, and prevents the sewage collected at the bottom of the trash storage box from jumping out of the front as much as possible. The purpose is to provide things.

[Means for solving the problem]

In order to achieve the above object, the wastewater treatment apparatus for a garbage truck according to claim 1 of the present invention prevents the sewage in the garbage storage box mounted on the garbage truck from flowing out to the front of the vehicle body. A sewage weir standing upright on the front bottom surface of the garbage storage box; and a sewage return plate erected on the bottom surface of the garbage storage box behind the vehicle body relative to the sewage weir. And an extended portion extending upward from the upper end of the inclined portion toward the rear of the vehicle body.

Further, the sewage treatment apparatus for a refuse collection vehicle according to claim 2 is:
A sewage weir is provided on the bottom surface of the front of the garbage storage box to prevent sewage in the garbage storage box mounted on the garbage collection vehicle from flowing out to the front of the vehicle body. A sewage drain portion protruding from the center in the height direction toward the rear of the vehicle body, an inclined portion that is continuously provided from an upper end portion of the sewage weir and inclines toward the rear of the vehicle body and rises, And an extending portion extending from the upper end toward the rear of the vehicle body.

[Action]

According to the present invention configured as described above, even if the garbage truck stops suddenly and the sewage collected at the bottom of the trash storage box moves forward by inertia, the sewage is erected behind the sewage weir. The sewage return plate or the sewage weir is provided at the sewage weir, and is returned backward by the sewage draining portion, the inclined portion, and the extension portion. This can prevent sewage from jumping over the sewage weir and flowing out from the front of the refuse storage box.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show the first embodiment. The differences from the conventional example shown in FIG. 4 are as follows.

That is, a waste plate 8 is provided which can move back and forth to compress and discharge the dust 5 stored therein, and a plate-like sewage weir 8 stands upright at the lower front part of the dust storage box 3 mounted on the body frame 2. The upper part of the sewage weir 8 is opened for cleaning and maintenance of the inside of the garbage storage box 3.
A sewage return plate 9 that is flat and extends over the entire length of the garbage container 3 in the width direction of the garbage storage box 3 at a position separated by a predetermined distance behind the sewage weir 8.
Is erected on the floor plate 3a of the garbage storage box 3.

The sewage return plate 9 includes a linear inclined portion 9a that rises inclining rearward, and a horizontal portion (extended) that is integrally connected to the upper end of the inclined portion 9a and extends horizontally toward the rear of the vehicle body. 9b, and the height of the sewage return plate 9 is
The height of the sewage weir 8 is set to be substantially the same as that of the sewage weir 8, so that the opening above the sewage weir 8 is not obstructed by the presence of the sewage return plate 9.

The upper end of the sewage weir 8 and the upper end of the sewage return plate 9 are connected by a connecting rod 10.

By providing the sewage return plate 9 in this way, even if the garbage collection vehicle stops suddenly and the sewage 7 collected at the bottom in the garbage storage box 3 moves forward due to inertia, the sewage 7 is retained in the sewage weir 8. Is returned along the inclined portion 9a and the horizontal portion 9b of the sewage return plate 9 erected from the rear, so that the sewage 7 does not jump over the sewage weir 8.

Although the inclined portion 9a in the above embodiment is straight, it is needless to say that the inclined portion 9a may be curved. Also,
The horizontal portion 9b may be slightly inclined with respect to the horizontal direction.

FIG. 3 shows another embodiment. In the above embodiment, the sewage return plate 9 is provided separately from the sewage weir 8, but in this embodiment, the sewage weir 18 itself is provided with sewage. It is provided with a configuration that does not jump over this.

That is, a sewage drain 18a protruding rearward in a V-shape is provided on the side surface of the flat sewage weir 18 substantially at the center in the height direction on the rear side of the vehicle body. The upper part of the sewage weir 18 has a slope 18
and a horizontal portion (extended portion) 18c integrally connected to the upper end of the inclined portion 18b and extending horizontally toward the rear of the vehicle body.

As a result, the garbage truck stops suddenly and the garbage storage box 3
Even if the sewage 7 collected at the bottom inside moves forward by inertia,
The upward flow of the sewage is first blocked by the sewage drain 18a, and the sewage is returned to the rear along the horizontal portion 18c from the inclined portion 18b of the sewage return portion 18d.
Never jump over.

The horizontal portion 18c may be slightly inclined with respect to the horizontal direction.

[Effect of the invention]

Since the present invention is configured as described above, the sewage collected inside the garbage storage box is removed from the front of the garbage storage box every time the garbage collection vehicle stops suddenly without providing a sewage tank on the bottom of the garbage storage box. It can be prevented as much as possible from scattering on the rear surface of the cab. In addition, there is an effect that the structure is relatively simple and can be easily applied to existing refuse collection vehicles.
