Description

[Detailed description of the invention] The present invention relates to a garbage discharge device for a garbage collection vehicle, and in particular to a garbage collection vehicle that is capable of suppressing the rise of garbage on the pressing surface of a discharge plate that reciprocates in the front and rear directions into a garbage storage chamber. Concerning car dust evacuation devices.

Generally, garbage collection vehicles that 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 back and forth 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 that can scoop up the garbage when compressing it in the storage box, improving the efficiency of compressing the garbage.
Ru.

For this reason, while the hydraulic cylinder device installed in the cylinder chamber on the back side of the discharge plate is driven to compress and load the garbage into the garbage storage chamber, the garbage rises upward along the pressing surface, causing the garbage to collapse. There was a problem in that a portion of the discharge plate climbed over the top surface of the discharge plate and fell 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.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a garbage discharge device for a garbage collection vehicle that can prevent garbage from rising on the pressing surface of a discharge plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a garbage discharge device for a garbage collection vehicle according to the present invention will be described below 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.

Preferably, the hydraulic cylinder device 12 uses a telescope type hydraulic cylinder having a multi-stage tube-shaped rod so that a sufficient number of movable strobes can be secured.

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 that extends substantially horizontally toward 1, and the tip of this flange 14 is chamfered to be tapered.

According to the present invention, the pressing surface 1 of the discharge plate 10
3 has a plurality of protruding claws 15.15.3 for preventing dirt from rising. ..., 15 are provided so as to protrude from the pressing surface 13.

According to this embodiment, these protruding claws 15.15. ...
. . , 15 are formed in the shape of a triangular pyramid, and, as is clear from FIG. 3, are arranged in a staggered manner in the upper half region of the pressing surface 13.

Next, the operation of the above-mentioned garbage discharge 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 shown by the solid line 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. Compact the garbage by

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

Inject the garbage into the storage chamber 3 again from the input port 5, and then remove it from the discharge plate 1.
0 is reciprocated to perform the work of compressing and loading garbage.

During this compression process, dirt rises on the pressing surface 13 of the discharge plate 10, but in the upper half region of the pressing surface 13, the protruding claws 15, 15. . . . 15 prevents the dirt from rising, so the pressing surface 1 of the pressing plate 10 of the discharge plate 10
It is possible to prevent dust from going up the top surface of the discharge plate 10 and falling into the cylinder chamber 11 on the back surface of the discharge plate 10.

In addition, dust and dirt may be removed from the protruding claws 15, 15. ....... 15, when the dust passes through the protruding claws 15.15. ...15
Since it is crushed by

The reference numeral 16 in FIG. 2 indicates a scraper, and this scraper 16 is made of, for example, a rubber plate or a flexible plastic plate, and the tip of the scraper 16 is attached to the upper surface of the flange 14 of the discharge plate 10. The amount of protrusion is adjusted in advance to allow sliding contact.

According to such a scraper 16, the dust adhering to the upper surface of the flange 14 can be scraped off into the dust storage chamber 3.

As is clear from the above explanation, according to the present invention, since a plurality of protruding pawls are arranged on the pressing surface of the discharge plate, it is possible to prevent the dust from rising on the pressing surface during the compression process, and the upper surface of the discharge plate The amount of dust that falls onto the back side of the discharge plate after climbing over it can be kept to an extremely small amount.

Further, since coarse dirt rising up on the pressing surface is crushed by the protruding claws, the compression efficiency can be increased compared to the conventional one having a flat pressing surface.
