Description

[Detailed description of the invention] (a) Industrial application field This invention is a garbage truck in which garbage is pushed into a garbage storage box by a pusher plate in the garbage truck, and when the pusher plate pushes the garbage, sewage, etc. is scattered backwards. It is used in the field of preventing

(b) Prior Art Conventionally, a garbage truck has been configured to use a scraping plate to scrape up the garbage thrown into the dustbin, and to push the garbage on the scraping plate into a garbage storage box using a pushing plate.

(c) Problems to be solved by the invention However, in the case of the above structure, when the pushing plate is used to push, the sewage in the garbage and the broken glass, plastic, etc. It may scatter backwards through the gap with the board.
It was extremely dangerous for workers.

(d) Means for Solving the Problems The present invention attempts to solve the above-mentioned drawbacks, and is provided with a packer having a garbage inlet at the rear of the garbage storage box, and a packer with a garbage inlet in the back of the garbage storage box. In a garbage truck that is provided with a scraping plate that scrapes thrown garbage upward and a pushing plate that pushes the garbage scraped up by the scraping plate into a storage box, a pushing plate is provided below the back of the pushing plate. At times, a pipe is provided to cover the gap between the pushing plate and the scraping plate, and the pipe is provided with holes in at least two places, and one end of a support rod bent appropriately is inserted into the hole, and the one end is inserted into the inner surface of the pipe. This invention relates to a device for preventing scattering of sewage, etc. in a garbage truck, in which the other end of the support rod is pivotally supported in a swingable manner at the lower part of the rear surface of the push plate.

(e) Function The garbage inputted from the input port is scraped up by the scraping plate, and the garbage on the scraping plate is pushed into the garbage storage box side by the pushing plate.

At that time, the glass bottles and plastic bags in the garbage are crushed, and the broken glass pieces and sewage inside the plastic bags try to scatter backwards through the gap between the pushing board and the scraping board, but the gap is behind the pushing board. It is shielded by a pipe suspended at the bottom to prevent it from flying backwards.

(f) Example The following example will be explained with reference to the drawings. 1 indicates the vehicle body 2.
A garbage storage box is mounted on the storage box 1, and a packer 3 is provided in communication with the rear of the storage box 1.

The packer 3 is supported at the upper end of the storage box 1 so as to be able to rotate upward, and a garbage inlet 4 is connected to the rear part of the packer 3.
is provided.

Further, inside the trash can 3, there is rotatably provided a scraping plate 5 that scrapes up the garbage thrown in from the garbage input port 4 at the lower part, and the garbage scraped up by the scraping plate 5 is placed in the storage box 1 at the upper part. A push-in plate 6 for pushing in is swingably provided.

7 is a hydraulic cylinder for swinging the pushing plate 6.

The pushing plate 6 has a pushing plate main body 8 that comes into direct contact with the garbage, and a box-shaped reinforcing frame 9 for reinforcing the main body 8 welded to the back of the main body 8. is a scattering prevention device 10 that prevents sewage etc. from scattering from the gap between the raking plate 5 and the pushing plate 6;
is provided.

The scattering prevention device 10 will be explained below.
1... is a pipe that is provided below the reinforcing frame 9 and shields the gap between the scraping plate 5 and the pushing plate 6 when pushing the garbage, and the pipe 11... has a substantially cylindrical cross section and is linear. There are multiple locations. The plurality of pipes 11... have the same structure, so to explain one of them, holes 12, 12 are provided at the top of both ends of the pipe 11, and the holes 12,
One end of the support rods 13, 13 bent in a U-shape is inserted through the pipe 12, and the other end is connected to the pipe 11.
It is engaged with the inner surface.

The other ends of the support rods 13, 13 are supported by brackets 14, 14 welded to the lower part of the reinforcing frame 9 so that they face each other and are parallel to the push plate 6. This allows the pipe 11 to Support rod 1
It is designed to be able to swing somewhat around one end or the other end of 3 and 13.

15... is a reinforcing pipe for shielding the gap between the pipe 11... and the reinforcing frame 9, and the reinforcing pipe 1
5 is supported at each end of a support rod 13 that protrudes from the bracket 14.

FIG. 6 shows another embodiment, in which the pipe holes in the previous embodiment are made into notched holes 12', 12', and U-shaped support rods 13', 13' are inserted into the notched holes 12', 12'. , support rod 13' for the pipe 11' on the pushing plate side,
It is swingably supported via 13'.

In addition, although the support rod is formed into a U-shape in the embodiment, it is not necessarily limited to the U-shape.
Any structure that can engage with the pipe and swingably support the pipe will be satisfactory.

The present invention has the above-mentioned structure, and its operation will be explained next. In Fig. 1, when garbage is thrown in from the garbage inlet 4 of the packer 3, the scraping plate 5 rotates in the direction of the arrow to collect the garbage at the bottom of the packer 3. Raise it up and stop at the solid line position.

Next, the pushing plate 6 swings from the solid line position to the one-dot chain line position due to the extension of the hydraulic cylinder 7, thereby pushing the garbage on the scraping plate 5 into the storage box 1.

By the way, when the pushing plate 6 is pushed in, there is some gap between the lower end of the pushing plate 6 and the scraping plate 5. Fragments such as plastics try to scatter backwards from the gap, but the gap is blocked by a plurality of pipes 11...
Moreover, since the gap between the pipes 11 and the reinforcing frame is covered by the auxiliary pipes 15, it is possible to reliably prevent dirty water and the like from scattering to the rear.

Furthermore, even if a hard substance in the garbage hits the pipes 11, the pipes 11 swing to reduce the impact.

(g) Effect of the invention As described above, the present invention has a supporting rod swingably provided at the lower part of the back of the pushing plate, the pipe is supported by this supporting rod, and the gap between the pushing plate and the scraping plate is fixed by the pipe. Since the pipe is shielded, it is possible to prevent sewage, glass, plastic, etc. fragments from scattering backwards, and it is also possible to prevent pipes, etc. from being damaged due to contact with hard dust.

In addition, since the support rods are inserted through holes made in the pipes, the gaps between each pipe can be made very small, and the pipes can be extended to the side of the package, which further prevents scattering. can be made certain.
