Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of Application The present invention is applied to the field of garbage trucks that perform collection work by pushing garbage put into a packer into a garbage container using a pushing device. It is something that is used.

(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 of 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 container from the above state using the discharge plate inside the container, you will need a drive device with a very large output, making it expensive.Also, if you try to dump the container and discharge it, it will generate dust. remains in the container, causing the entire center of gravity to move backwards and roll backwards, causing the garbage truck to fall into the bit when discharging into the bit, resulting in an accident resulting in injury or death.

Then, a garbage container is mounted on the vehicle body, a puffer is connected to the rear of the container, a pushing device inside the puffer pushes the garbage into the container, the puffer is rotated upward, and the container is dumped. In a garbage truck for discharging garbage from a container, a rope is provided with one end attached to the vehicle body and the other free end having a scraping member facing into the container, and an intermediate portion of the rope is placed in the container, A garbage discharge auxiliary device for a garbage truck, characterized in that the scraping member is moved by a dumping operation of a container.

(e) Operation When performing garbage collection work, operate the pushing device,
The garbage put into the puffer bag is pushed into the container by a pushing device, and the pushing operation is continued until the container is filled with garbage.

At this time, near the end of the collection work, the garbage stored in the rear of the container is compressed to a high density, and the scraping member of the ejection auxiliary device, one end of which is attached to the vehicle body, is positioned in the dense garbage. Become.

Next, when discharging garbage, the puffer is first rotated upward to open the rear of the container. The container is then dumped backwards and the garbage is discharged. At this time, since the scraping member in the garbage is pulled rearward as the container is dumped, the highly compressed garbage is broken up and the entire garbage can be smoothly discharged.

(f) Examples Below, examples will be explained using drawings. (1) is a vehicle body (2
), the dump frame (1) is supported so as to be tiltable backwards, and a garbage storage container (3) is fixed to the dump frame (1), and a dump frame is provided between the vehicle body (2) and the dump frame (1). A device (not shown) allows the container (3) to be dumped.

A puffer (4) is connected to the rear of the container (3), and the puffer (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 puffer (4) is pivoted at the upper rear end of the upper tν container (3), and can be rotated upward by a backer dump cylinder (7) provided between the container (3) and the puffer (4). It has become.

At the top of the communication port (6) of the backer (4), there is a container (3).
A cover (8) is provided as a part of the puffer bag (4) to prevent the dust inside from flowing back to the puffer bag (4) side, and the cover (8) has reinforcing girders ( 9) (9
) is fixed.

Inside the puffer bag (4), there is a pushing device (10) for pushing the garbage thrown in from the inlet (5) into the container (3) side.
is provided.

The pushing device (lO) includes a pushing plate (11) and a pushing plate (1).
1) A cylinder (
13) and a cylinder (15) that rotates the pushing plate (11) via links (14) (14), and the pushing plate (11) is rotated backward, lowered, and raised in the previous movement cycle. It is designed to push in dust when activated.

(17) is an ejection auxiliary device, and the ejection auxiliary device (17) has one end of a rope (18) attached to a mounting member (13) of a vehicle body (2), and an intermediate portion attached to a container (3).
) along the front surface (20) and top surface (21) of the container (3) and the free end of the tip from between the container (3) and the puffer (4).
), and a disk-shaped scraping member (22) is provided at the free end, and this scraping member (22) is adapted to catch on the garbage.

Due to the above structure, when the container (3) is empty, the free end of the rope (18) hangs down as shown by the solid line in Figure 1, and when the container (3) is full of garbage, it extends forward as shown by the dashed line. It is located in the garbage. (23)-
is a guide member attached to the container (3), and the guide member (
23)- to prevent the rope (18) from breaking.

Note that the drawing member and the pushing device are not limited to the structure of the embodiment, and the scraping member may have any structure as long as it can catch on the garbage, and the pushing device can push the garbage within the loose force into the container side. Furthermore, by providing a rotatable arm or link on the container and interposing the arm or link in the middle of the rope, it is possible to adjust the amount of dump movement of the container and the amount of movement of the free end of the rope. It is possible.

The present invention has the above-mentioned structure, and the operation will be explained next. Before the collection work is performed, the rope (18) is attached as shown in Fig. 2.
The free end of is in a hanging state. In this state, both cylinders (13) and (15) are operated to interlock the pushing plate (11) in cycles. As a result, the garbage input from the input port (5) is pushed into the container (3) by the pushing plate (11), and by repeating this process, the container (3) is filled with garbage as shown in Figure 3. , finish the collection work.

At this time, at the beginning of the collection operation, the free end of the rope (18) swings up and down every time the garbage passes through the communication port (8), but as the collection operation approaches the end, the garbage becomes denser at the rear of the container (3). At the same time, the scraping member (22) of the discharge assisting device (17) comes to be located in the garbage as shown in FIG.

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

After the puffer bag (4) is rotated upward, the container (3) is dumped by a launching device as shown in FIG. 4, and the garbage inside the container (3) is discharged. By the way, as the dumping operation of the container (3) also pulls the free end of the rope (18) backward, the scraping member (22) can catch on the garbage and break up the highly compressed garbage. The entire garbage can be smoothly discharged.

(g) Effects of the invention As described above, the present invention provides a rope with one end attached to the vehicle body and the other free end having a scraping member facing inside the container, and the intermediate part of this rope is placed in the container, When the garbage is pushed into the container, the scraping member is positioned in the garbage, and the scraping member can be pulled when the container is dumped, so that the garbage in the container can be smoothly discharged. This makes it possible to reliably eliminate the causes of backward rollover accidents that occur in the past.
