[Problem to be solved by the invention]

However, in the case of the above conventional example, although the mechanism is relatively simple, only reciprocating one loading panel, when loading garbage into the container body, small garbage and sewage are loaded. If it goes around the back of the panel (the opposite side of the container from the loading panel), and if it gets deep inside, it is difficult to take it out, and in some cases, it may reduce functionality or damage the equipment due to dirt. There was a problem in that it could lead to problems.

In view of the above, the present invention is designed to prevent small waste, sewage, etc. from getting around to the back of the loading panel when loading waste into the container body, and even if it gets around, it can be easily prevented.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a container main body 1. The container main body 1 is provided with an input port 2 at the front thereof, and is open at the rear end. 4 are connected. The waste thrown into the hopper 5 from the input port 2 is compressed and pushed into the container body 1 by a pushing device 6 disposed below.

As shown in detail in FIG. 2, the pushing device 6 includes a pair of approximately triangular upper panels 7a arranged in 1L rows along the side plate 8 of the hopper 5, and a pair of upper panels 7a extending over almost the entire width of the hopper 5. A loading panel is provided, which includes an extending, packet-shaped lower panel 7b, which pushes the waste thrown into the hopper 5 into the container body 1.

This upper panel 7a is a frame 9 of the container body 1.
A rocking mill on the pivot 10 installed in the ? A lower panel 7b is rotatably supported on the lower end of the upper panel 7a via a pin 11.

The upper end of a filter panel cylinder (second cylinder) 12 is rotatably connected to a pivot shaft 10 provided on the frame 9, and the lower end of this inside cylinder 12 is connected to the lower panel 7b via a lower panel hinge 13. are rotatably connected. As a result, the lower panel 13 swings back and forth about the pivot 10 as the lower panel cylinder 12 expands and contracts.

On the other hand, a pair of upper panel cylinders (second cylinders) 15 whose base ends are rotatably supported by the container body 1 via a fixed hinge 14 are disposed outside the side plate 8. The upper end of pin 16
It is connected to the upper panel 7a via. As a result, by the expansion and contraction of the upper panel cylinder 15,
The upper panel 7a is configured to swing back and forth about a pivot 10.

Note that the side plate 8 is provided with an arcuate notch 8a through which the pin 16 is inserted when the upper panel 7 swings so that the swing is not hindered.

By configuring as described above, the lower end of the lower panel 7b follows a locus 17 that is a combination of four arcuate loci 17a to 17d as shown.

The bottom plate 18 of the hopper 5 is formed in a shape along the lower loci 17c and 17d of the lower panel 7b, that is, by joining two plates 18a and 8b.

Next, the operation of the above embodiment will be explained with reference to FIG.

FIG. 3(d) shows a state in which the work of pushing the countertop has been completed, and in this state, the lower panel 7b is compressed to cover the countertop that has been pushed into the container body 1.
In addition to preventing the backflow of waste and sewage, a space for loading the waste is secured so that this loading can be carried out efficiently. From this state, one cycle of loading is started.

That is, in this state, after loading waste into the hopper 5 from the input port 2, a reversing process is performed in which the lower panel 7b is reversed along the trajectory 17a by contracting the lower panel cylinder 12 (FIG. 3(d)). →Figure (a)).

Next, by contracting the upper panel cylinder 15, a return stroke is performed in which the lower panel 7b is returned along the trajectory 17b via the upper panel 7a (FIG. 3(a)→FIG. 3(b)).

Then, by extending the lower panel cylinder 12 in this state, the upper panel 7b is rotated along the locus 17c, thereby performing a scraping process to scrape the waste in the hopper 5 (Fig. 3 (b) → Same figure (C)).

Thereafter, by extending the upper panel cylinder 15, the lower panel 7b is advanced along the trajectory 17d via the upper panel 7a, thereby performing a pushing process to push the waste into the container body 1, returning it to the initial state. (FIG. 3(C)-FIG. 3(d)).

In the above process, the hopper bottom plate 18 is located close to the input port 2 at the front part, and its shape is almost the same as the locus 17 of the lower end of the lower panel 7b, so the waste is placed on the lower panel (loading panel). 7b, it is neatly pushed into the container body 1. Even if the dirt gets around to this back side through the gap between the lower panel 7b and the hopper bottom plate 18, the dirt will only remain inside the hopper 5.
This can be pushed into the container body 1 in the next cycle, and cleaning is easy.
