Description

[Detailed explanation of the invention] (Industrial application field) This invention is a garbage collection vehicle (hereinafter referred to as a collection vehicle).
The present invention relates to a device for preventing sewage from flowing out from a joint between a garbage storage box (hereinafter referred to as the storage box) and a garbage input box (hereinafter referred to as the input box).

(Prior Art and Problems) As shown in FIG. 2, a collection vehicle includes a storage box 1 which is placed on a chassis and whose rear end is pivotally supported by the chassis to dump garbage when discharging garbage, and the storage box 1. A front opening 2 is connected to the rear opening of the storage box 1 by being pivotally supported at the upper part of the rear end.
A (see Fig. 4) is connected to the dumping box 2 which is dumped diagonally upward, but during the garbage loading operation and when traveling, sewage overflowing from the compressed garbage in the storage box 1 is connected to the above-mentioned junction. It is necessary to prevent it from flowing out from the outside.

Conventionally, the following devices have been used to prevent this problem.

That is, as shown in FIG. 3, the sealing material has a substantially chestnut-shaped cross section and a cavity 3 having substantially the same shape inside.
Packing 3 (made of rubber material) having a is used.

As shown in FIG. 4, the packing holder shown in FIG. 5 (having a substantially dovetail-shaped cross section) is attached by welding, and the packing 3 is applied with an adhesive and fitted and bonded to the packing receiving metal fitting 5.

FIG. 6 is a sectional view taken along the line A-A' in FIG. 4, showing the state in which the packing 3 is attached.

Therefore, when loading garbage and when driving,
The input box 2 is secured to the storage box 1 by a securing mechanism (not shown).
At this time, the packing 3 comes into pressure contact with the frame 6 (see Fig. 2) formed around the rear opening of the storage box 1, and the presence of the cavity 3a is removed. This produces smooth elastic deformation and is put into practical use as a watertight sewage outflow prevention device, but since it is a single cavity 3a, it is difficult to obtain uniform deformation over the entire area of the packing holder 5. It could not be said that it was a complete sewage outflow prevention device.

(Means for Solving the Problems) The present invention provides a fan which has a circular cross section and expands in the radial direction on either the storage box or the input box at the joint surface between the storage box and the input box. The reason is that a packing is installed in which a plurality of small cavities in the same shape and a single large cavity in the same fan shape that expands in the radial direction are arranged radially and at equal intervals.

(Example) The present invention is characterized by the shape of the packing, and its attachment means etc. are the same as those of the conventional example, so only the embodiment of the packing will be described with reference to the drawings.

As shown in FIG. 1, the packing 10 has a circular cross section and has three fan-shaped small cavities 10a that expand in the radial direction from the center, and a fan-shaped small cavity 10a that also expands in the radial direction. A single large cavity 10b is provided radially and at equal intervals, and the large cavity 10b
A mounting portion 10c is formed on the outer circumferential wall of the packing 3 on the b side, and is fitted into the packing receiving fitting 5 shown in FIG. 5.

Note that the packing 10 is made of a rubber material and can also be provided on the storage box 1 side.

(Effects) As described above, since the packing of the present invention, which is attached to the joint surface of the storage box and the input box, has a round, perforated shape, smooth elastic deformation is achieved due to the cooperative action of the three small cavities. , and the ability to follow uniform elastic deformation is improved due to the action of the large cavity, which has the effect of enhancing the sealing function to prevent the outflow of sewage.
