Description

[Detailed Description of the Invention] The present invention relates to a garbage collection vehicle, and more particularly to a garbage collection vehicle in which the strength of the front end of a sump provided at the bottom of the tailgate for temporarily storing garbage is reinforced.

In general, a garbage collection vehicle has a garbage storage box opened at the rear mounted on the chassis, and a tailgate with a built-in loading device is usually attached to the rear opening of the garbage storage box. A garbage storage device called a sump is installed at the bottom of the tailgate. There is.

Thus, the front edge of the sump is bent so as to be parallel to the floor of the garbage storage box, and this portion rests on the lower frame member of the rear frame.

However, this type of conventional sump does not have sufficient strength at its front end, and there has been a demand for improvement in this respect.

The present invention aims to improve the drawbacks of conventional sumps and to provide a garbage collection vehicle that can strengthen the front edge of the sump without increasing the rear overhang required by regulations.

In order to achieve this purpose, the present invention fixes a rear frame body formed by framing an upper frame member, a lower frame member, and a pair of side frame members in a rectangular shape to the rear opening of a garbage storage box, and In a garbage collection vehicle equipped with a tailgate with a sump at the rear of the body, the side frame members of the rear frame body are arranged across the lower area so as to form a gap between the front end of the sump and the lower frame member. The surface dimension is configured to be smaller than the cross-sectional dimension of the upper region, and the front end of the sump is bent almost parallel to the floor surface of the garbage storage box so as to cover the upper part of the above-mentioned gap. This is characterized in that a reinforcing member having an L-shaped cross section is attached to fill the above-mentioned gap, and a packing that can be tightly attached to the lower frame member is fixed to the outer surface of the reinforcing member along the longitudinal direction.

An embodiment of a garbage collection vehicle according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 indicates the chassis of a garbage collection vehicle, and on top of this chassis 1 is a garbage storage box 2.
is listed. A storage chamber 3 is formed inside this garbage storage box 2, and the collected garbage can be stored inside until it goes to the incineration plant. This accommodation chamber 3 has a flat floor surface 3a.

At the rear of the garbage storage box 2, a rear frame 8 is installed, which is formed by framing an upper frame 5, a lower frame 6, and a pair of side frame members 7, 7 in a rectangular shape. A tailgate 10 equipped with a garbage inlet 9 is integrally attached to the rear of the vehicle, and a sump 11 is provided below the tailgate 10 to temporarily store the garbage thrown in through the inlet 9. It is provided. This sump 11 has the form of a receiving groove with an inner cylindrical surface.

A rotating shaft 12 is installed in the space above the sump 11 along the lateral direction, and the rotating shaft 12 is rotatably driven by a drive means such as a hydraulic motor (not shown). Further, a rotating plate 13 is fixed to the rotating shaft 12, and has a curved rake face 13a on the upper surface.

On the other hand, reference numeral 15 indicates a pusher plate that can swing around a pivot point 16, and this pusher plate 1
A rod side 17a of a pushing cylinder device 17 is pivotally attached to the upper end of the push-in cylinder device 5, and a base side 17b thereof is pivotably attached to the upper frame member 5 via a bracket 18.

The bracket 18 also includes a deflector 1.
The upper end of the deflector 9 is supported, and the deflector 19 extends diagonally rearward.

Next, the configuration of the main part of the present invention will be explained. The side frame member 7 that constitutes the rear frame body 8 is composed of a member having a hollow rectangular cross section, and the dimensions of the cross section are the upper area 7A. The lower region 7B is different in that the cross-sectional dimension of the lower region 7B is smaller than that of the upper region 7A.

On the other hand, the front end of the sump 11 is bent so as to be substantially parallel to the floor surface 3A, and below the front end 11a, the lower frame member 6 and the sump 11 are bent.
A gap 20 is formed between them. A reinforcing member 21 having an L-shaped cross section is fixed directly below the front end portion 11a to reinforce the strength of the front end portion of the sump 11.

Note that a packing 22 is arranged between the reinforcing member 21 and the lower frame member 6 to prevent dust from falling under the chassis.

As is clear from the above description, according to the present invention, the cross-sectional dimension of the lower region of the side frame member constituting the rear frame of the garbage storage box is reduced, and the space between the lower frame member and the front end of the sump is reduced. A gap is formed, and by using this gap, a cross section of L is formed on the outer surface of the front end of the sump.
Since the letter-shaped reinforcing member is fixed, the strength of the front end of the sump is reinforced without increasing the rear overhang of the vehicle, and deformation of the front end of the sump can be prevented.

Further, since a gasket that can be tightly attached to the lower frame member is fixed to the outer surface of the reinforcing member along the longitudinal direction, dust does not fall out from the gap between the front end of the sump and the lower frame member.

Claims (1)

[Scope of utility model registration request] A rear frame formed by framing an upper frame material, a lower frame material, and a pair of side frame materials in a rectangular shape is fixed to the rear opening of the garbage storage box, and a tailgate equipped with a sump is attached to the rear of this rear frame body. In the attached garbage collection vehicle, the side frame members of the rear frame body have a cross-sectional dimension in the lower region that is larger than a cross-sectional dimension in the upper region so as to form a gap between the front end of the sump and the lower frame member. The front end of the sump is bent almost parallel to the floor of the garbage storage box so as to cover the upper part of the gap, and the outer surface of the front end has an L-shaped cross section to fill the gap. A garbage collection vehicle is equipped with a reinforcing member, and a gasket is fixed to the outer surface of the reinforcing member in the longitudinal direction so as to be in close contact with the lower frame member.
