Description

Detailed Description of the Invention (a> Industrial Application Fields The present invention is used in the field of garbage trucks that collect garbage by pushing the garbage put into a packer into a garbage container using a pushing device. It is something that

(b) Conventional technology A conventional garbage truck has a packer connected to the rear of the garbage container.
A pushing device is installed inside the packer, and when garbage is collected, the garbage put into the packer is pushed into the container by the pushing device to collect the garbage, and when discharging the garbage, the packer is rotated upward. After this, the waste is discharged by moving the discharge plate inside the container or by dumping the container.

(C) Problem to be solved by the invention In the above-mentioned garbage truck, at the beginning of the garbage collection operation, the garbage is sent to the front of the container without being compressed very much, but near the end of the collection operation, that is, the container becomes full of garbage. The pushing force from the pushing device acts on the garbage at the rear of the container, compressing the garbage at a high density and creating a very large frictional resistance with the inner surface of the container, making it impossible to discharge the garbage smoothly.

Therefore, if you try to discharge the above-mentioned condition using the discharge plate inside the container, there is a drawback that a drive device with a very large output is required and becomes expensive.Also, if you try to dump the container and discharge it, the garbage will be removed from the container. Since the garbage truck remains in the pit, the center of gravity of the entire garbage truck moves backwards, causing the garbage truck to roll backwards, causing the garbage truck to fall into the pit, resulting in an accident resulting in injury or death.

(d) Means for Solving the Problems The present invention solves the above-mentioned problems by mounting a garbage storage container on the vehicle body, connecting a packer to the rear of the container, and disposing the container inside the packer. In a garbage truck that pushes garbage into a container with a pushing device and rotates a packer upward to discharge the garbage from the container, a part of the packer or pushing device is configured to be located in the garbage at the rear of the container. This invention relates to a garbage discharge auxiliary device for a garbage truck, in which a discharge auxiliary member is attached to a garbage vehicle.

(e) Operation When performing garbage collection work, the pushing device is operated to push the garbage put into the packer into the container using the pushing device, and the pushing operation is continued until the container is filled with garbage.

At this time, near the end of the collection operation, the garbage stored in the rear part of the container is compressed to a high density, and the discharge assisting member attached to the para-force or pushing device is positioned in the high-density garbage.

Next, when discharging garbage, the packer is first rotated upward to open the rear of the container.

At this time, the discharge auxiliary device inside the garbage is also pulled backwards, so the highly compressed garbage is broken up.

Thereafter, the dust inside the container is smoothly discharged by appropriate means.

(f) Example The following example will be explained using drawings. (1) is a vehicle body (2)
a dump frame supported upwardly so as to be tiltable backward; a garbage container (3) is fixed to the dump frame (1);
The container (3) can be dumped by a launching device (not shown) provided between the vehicle body (2) and the dump frame (1).

A packer (4) is connected to the rear of the container (3), and the packer (4) has an input port (5) at the rear and a communication port (6) communicating with the container (3) at the front. have.

Further, the upper part of the packer (4) is pivotally supported on the upper rear end of the container (3), and can be rotated upward by a packer dump cylinder (7) provided between the container (3) and the packer (4). It has become.

A cover (8) is provided as part of the packer (4) above the communication port (6) of the packer (4) to prevent the dust in the container (3) from flowing back toward the packer (4). The cover (8) is fixed to reinforcing beams (9) (9) extending on both sides.

Inside the packer (4), there is a pushing device (a cylinder (13) that moves up and down along the side frame (12) and a pushing plate for pushing the garbage thrown in from the input port (5) into the container (3) side. It consists of a cylinder (15) that rotates (11) via a link (14) (14), and the pushing plate (11) is operated in a cycle of backward rotation, lowering, forward movement, and raising to push the garbage. It's starting to look like this.

(16) is an auxiliary cover attached so as to be raised and lowered together with the push plate (11), and like the cover (8), this auxiliary cover (16) is designed to prevent the dust in the container (3) from falling into the packer (4).
It is designed to prevent backflow.

(17) (17) is a discharge auxiliary member attached to the inner surface of the packer (4), and the discharge auxiliary member (17) (17) plays the role of breaking up the garbage in the container (3) when discharging the garbage. ing.

As shown in FIGS. 1 and 2, the ejection auxiliary members (17) (17) have U-shaped mounting members (18) fixed to the left and right sides of the inner surface of the packer (4). )
A structure in which a connecting rod (19) (19) is rotatably attached to (18), and a disc-shaped scraping plate (20) (20) is attached to the tip of the rod (19) (19). It has become.

When the container (3) is empty, it is in a hanging state as shown by the dotted chain line in FIG. 1, and when the container (3) is full of garbage, it extends forward as shown by the solid line and is located in the garbage.

In the example, the ejection auxiliary member is attached to the inner surface of the packer, but it is also possible to attach it to a part of the cover, reinforcing girder, or pushing device, and it can also be in a state where it extends forward instead of in a swinging type as in the example. Even if it is a fixed type, it has the same effect.

Also, the connectors are not limited to rods, but wires, etc.
A chain can also be used, and the scraping plate can also have the same effect as long as it has a structure that can catch on dirt.

Furthermore, the pushing device is not limited to the structure of the embodiment, and any structure that can push the garbage in the packer into the container side will have the same effect.

The present invention has the above-mentioned structure. Next, the operation will be explained. Before the collection work is performed, the discharge assisting member (1
7) is in a drooping state.

In this state, both cylinders (13) and (15) are operated to move the pushing plate (11) in cycles.

As a result, the garbage input from the input port (5) is removed from the push plate (1).
1), and by repeating this process, the container (3) is filled with garbage as shown in FIG. 4, and the collection work is completed.

At this time, at the beginning of the collection operation, the discharge auxiliary member (17) (17) swings up and down every time the garbage passes through the communication port (6), but as the collection operation approaches the end, the garbage is removed from the rear of the container (3). In a highly compressed state, the pair of left and right discharge assisting members (17) (17) both come to be located in the garbage as shown in FIG.

When discharging garbage next time, extend the packer dump cylinder (7) from the state shown in Fig. 4 to remove the packer (
4) upwards to open the rear of the container (3).

At this time, as shown in FIG. 5, when the backer (4) is rotated upward, the ejection auxiliary members (17) (17) are also pulled rearward, and the packer (4) is rotated upwardly, and then as shown in FIG. The container (3) is then dumped by a launching device, and the dust inside the container (3) is discharged.

At this time, the highly densely compressed garbage is in a broken state, so the garbage can be smoothly discharged.

In the embodiment, the container is dumped to discharge the garbage, but it is also possible to provide a discharge plate inside the container and discharge the garbage using the discharge plate.

(g) Effects of the Invention As described above, the present invention has an ejection auxiliary member attached to a packer that can rotate upward or a pushing device located inside the packer, and when garbage is pushed into a container, the ejection auxiliary member is positioned in the garbage. By rotating the packer upward, the ejection assisting member can be pulled.
It is possible to reliably break up the dust in the container, especially the highly compressed dust at the rear of the container, and to smoothly discharge the dust inside the container, thereby reliably eliminating the causes of backward rollover accidents that occur in the past. It is possible.
