Description

[Detailed description of the invention] The present invention relates to a garbage fall prevention device for a garbage collection vehicle, and in particular, while the discharge plate reciprocates in the front and back force direction within the garbage storage chamber, the garbage exceeds the upper surface of the discharge plate and is discharged. This invention relates to a garbage fall prevention device for a garbage collection vehicle that can prevent garbage from falling into a cylinder chamber on the back side of a plate.

Garbage collection vehicles that are generally configured to input garbage into the storage chamber through an input port formed on the top surface of the garbage storage box are equipped with a discharge plate that can reciprocate in the front and rear directions within the garbage storage chamber.
This discharge plate is used to compress the garbage and load it into the storage chamber, and at the place where the garbage is disposed of, the rear door is opened and the discharge plate is pushed backwards to discharge the compressed garbage out of the garbage storage box. .

The front surface of this discharge plate is an inclined pressing surface so that the garbage can be scooped up when compressing the garbage in the storage box, and there is also a space between the outer peripheral surface of the discharge plate and the inner wall surface of the garbage storage chamber. An appropriate gap is formed between the discharge plate and the inner wall surface of the dust storage chamber to prevent the discharge plate from colliding with the inner wall surface of the dust storage chamber when the discharge plate reciprocates in the front and back direction within the dust storage chamber.

To do this, a hydraulic cylinder device installed on the back side of the discharge plate is driven to move the discharge plate back and forth, and when the garbage is compressed and loaded into the garbage storage chamber, some of the garbage touches the top surface of the discharge plate. It overflows and falls onto the back side of the discharge plate.

Cleaning work to remove this fallen dust is difficult, and if the fallen dust is left unattended, there is a problem in that it stains or damages the hydraulic cylinder device and its auxiliary devices.

Therefore, an object of the present invention is to provide a garbage fall prevention device for a garbage collection vehicle that can reliably prevent a part of the garbage from exceeding the upper surface of the discharge plate and falling onto the back side of the discharge plate. There is a particular thing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a device for preventing the fall of garbage for a garbage collection vehicle according to the present invention will be described with reference to the drawings.

In FIG. 1, a garbage storage box 4 having a garbage storage chamber 3 formed therein is mounted on a vehicle frame 2 of a garbage collection vehicle, which is generally designated by the reference numeral 1.

A garbage inlet 5 is formed in a part of the top wall of this garbage storage box 4, and garbage can be thrown into the garbage storage chamber 3 through this garbage inlet 5.

The garbage inlet 5 is normally closed by a canopy 6.

Further, the rear end of the garbage storage box 4 serves as a garbage discharge lower, which is opened and closed by a rear door 8.

A discharge plate 10 that can reciprocate in the front and rear directions within the garbage storage chamber 3 is incorporated in the garbage storage chamber 3. It is now possible to move toward the ejection lower from the retracted position shown in .

The discharge plate 10 is reciprocated by a hydraulic cylinder device 12 disposed within a cylinder chamber 11.

This hydraulic cylinder device 12 preferably uses a telescope type hydraulic cylinder having a multi-stage tube-shaped rod so as to ensure a sufficient movement stroke.

As shown in FIG. 2, the discharge plate 10
In the illustrated embodiment, the pressing surface 13 is inclined with respect to the horizontal plane by an angle of attack θ, so that the discharge plate 10 does not move into the garbage. When pushed in, the dust is scooped up along the pressing surface 13 to improve compression efficiency.

Furthermore, the cylinder chamber 1 is provided at the upper end of the discharge plate 10.
A flange 14 is provided extending substantially horizontally toward the flange 1, and the tip of the flange 14 is chamfered so as to be tapered.

A gap is formed between the upper surface of the flange 14 and the ceiling surface of the garbage storage chamber 3.

On the other hand, a hopper plate 15 that expands upward is attached to the front edge of the garbage inlet 5 of the garbage storage box 4, and a lower end 16 of this hopper plate 15 projects into the garbage storage chamber 3. It is set in.

Further, a scraper 17 is provided on the side surface 16a of the lower end portion 16.
is attached with screws 18.

This scraper 17 may be constructed of, for example, a rubber plate or a flexible plastic plate.
The amount of protrusion of the tip 7 is adjusted in advance so that it can slide into contact with the upper surface of the flange 14 of the discharge plate 10.

Further, in this embodiment, the scraper 17 has a plurality of scraper pieces 19, 19 as shown in FIG.
. . . , 19 are arranged with a slight interval between them.

Instead of these scraper pieces, a long rubber plate may be attached over the entire width of the discharge plate 10 in the lateral direction to serve as a scraper.

Furthermore, the scraper 17 does not necessarily need to be installed at the lower end 16 of the hopper plate 15 as shown in FIG. It is sufficient to set it just before 10.

Next, the operation of the above-mentioned garbage fall prevention device for the garbage collection vehicle will be explained.

The hydraulic cylinder device 12 is contracted to the maximum, the discharge plate 10 is placed in the retracted position as shown in FIG.

When the garbage is piled up, the canopy 6 is closed, and then the hydraulic cylinder device 12 is extended to move the discharge plate 10 forward toward the rear door 8 as shown by the imaginary line in FIG. Compress by surface 13.

Then, the hydraulic cylinder device 12 is contracted and returned to the retracted position.

Insert the garbage into the storage chamber 3 from the input port 5 again.
It reciprocates to carry out the work of compressing and loading garbage.

During this time, part of the dust that has risen up the pressing surface 13 of the discharge plate 10 adheres to the upper surface of the flange 14 of the discharge plate 10, as shown in FIG. Dust that has slid onto the upper surface of the housing 14 and adhered thereto is scraped off into the dust storage chamber 3.

Therefore, it is possible to reliably prevent dust from climbing over the upper surface of the flange 14 of the discharge plate 10 and falling to the cylinder chamber 11 side.

In addition, in FIG. 2, the symbols 20.20.・・・・・・
, 20 indicate triangular pyramid-shaped projecting claws projecting on the pressing surface 13, and these projecting claws 20, 20°...,
20 acts to effectively prevent the garbage from rising upward during the garbage compaction process.

As is clear from the above description, according to the present invention, a plurality of scraper pieces made of a flexible material and arranged with a slight interval between them are arranged over the entire width of the discharge plate in the lateral direction. Since the scraper is constructed by setting up the scraper, even if the upper surface of the discharge plate has horizontal undulations or some unevenness, each scraper piece can act independently and separate from the adjacent one. Even if a piece of debris is caught between any scraper piece and the top surface of the discharge plate, only that scraper piece will be lifted, and all the remaining scraper pieces and the top surface of the discharge plate will be lifted up. The press-sliding state between them is maintained, and as a result, it is possible to reliably prevent the dirt that has risen up the pressing surface of the discharge plate from climbing over the upper surface of the discharge plate and falling into the cylinder chamber.

Therefore, there is no need for cleaning work to remove dust that has fallen into the cylinder chamber, and it is possible to prevent the cylinder device and its auxiliary equipment from being contaminated and damaged due to the falling dust being left unattended.
