Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is applied to the field of a pushing mechanism for a garbage collection vehicle that increases the amount of garbage stored in a garbage storage box.

(b) Prior Art The pushing mechanism of a conventional garbage collection vehicle has a guide member 02 mounted inside a garbage input box 01, as shown in FIG.
An actuating plate 04 fitted with a support shaft 03 at its base.
and a first shaft whose tip is connected to the support shaft 03.
It consisted of a telescoping cylinder 05 and a second telescoping cylinder 08 whose base was pivotally supported on the bottom of the input box 01 and whose tips were pivotally supported by a tension link 06 and a press link 07. Since the actuating plate 04 can only be pushed up to the opening 09 of the input box 01, it will not be able to push the garbage inside the storage box 010 into high density, so the garbage inside the storage box 010 will not be compressed to a high density.
There was a problem that the amount of garbage stored in 0 was small.

(c) Problems to be Solved by the Invention The present invention has been made to solve the above-mentioned problems, and the actuating plate is positioned closer to the opening of the input box so that the garbage can be stored in the storage box at a high density. Furthermore, it has a pushing mechanism that allows pushing forward.

(d) Means for Solving Problems The present invention is characterized in that the garbage in the garbage storage box is contained by a pushing mechanism installed inside the garbage input box connected to the rear of the garbage storage box. In the garbage collection vehicle that is housed in a box, the pushing mechanism includes an actuating plate whose support shaft at its base is fitted into a downwardly inclined guide member attached to both front inner walls of the input box; a first telescopic cylinder whose tip is connected to a support shaft and allows the base of the actuating plate to slide up and down; its tip is pivoted to the tip of the actuating plate, and its base is pivoted at one end in front of the input box; a second telescoping cylinder pivotally supported on the other end of the substantially triangular arm; and a third telescoping cylinder having its tip pivotally supported on the intermediate end of the arm and swinging the arm up and down about its pivot support. This is what we have configured.

(e) Embodiment An embodiment of the present invention will be described below with reference to the drawings. A hinge pin 4 is attached to the rear upper end of a garbage storage box 3 mounted on a vehicle frame 2 of a garbage collection vehicle 1 so that a garbage input box 5 can swing. The rear part of the storage box 3 is connected to
The input box 5 has an opening 6 .

The input box 5 has an input port 7 formed at the rear thereof, and a bottom portion 8 formed in an arcuate shape, which is reinforced with an appropriate reinforcing member.

A pushing mechanism G that compresses and crushes the garbage and pushes it into the storage box 3 is housed in the input box 5.

The pushing mechanism G will be described in detail below. The input box 5 houses an actuation plate 9 having a width that touches both inner surfaces of the input box 5. The support shaft 10 has a first telescopic cylinder 1 whose base is supported 11 on the upper part of the input box 5.
The rollers 13 are connected to each other at the ends of the rollers 13 and are rotatably supported at both ends of the support shaft 10. The rollers 13 are fitted into guide members 14 mounted on both inner walls of the input box 5 and inclined rearward and downward. The base of the actuating plate 9 can move up and down along the guide member 14.

Reference numeral 15 denotes a second telescopic cylinder 15 whose tip is pivoted 16 to the tip of the actuating plate 9;
5 is pivoted 19 to the other end of a substantially triangular arm 18 whose one end is pivoted 17 in front of the input box 5.

20 has a tip portion pivoted to the upper end of the arm 18 21
This is a third telescoping cylinder whose base is pivotally supported 22 on the upper part of the input box 5. By the way, the base of the first telescoping cylinder 12 may be pivoted near the bottom 8 of the charging box 5, and the base of the third telescoping cylinder 20 may also be supported near the bottom 8 of the charging box 5.
It may be pivoted near the bottom 8 of the.

The present invention has the above-mentioned structure, and its operation will be explained next.

First, as shown in FIG.
2 is the most contracted position, and the second telescopic cylinder 15 and the third telescopic cylinder 20 are also the most contracted position,
The actuating plate 9 is held substantially horizontally in the raised position.

In this state, garbage is thrown into the throw-in box 5 through the throw-in port 7.

Next, as shown in FIG.
At the position where is extended to the maximum and the second telescoping cylinder 15 and the third telescoping cylinder 20 are extended, the actuating plate 9 can reach the bottom 8 of the input box 5,
The garbage thrown in at this time is compressed and crushed within the throwing box 5.

Next, when the first telescopic cylinder 12 is contracted the most along the guide member 14, the state shown in FIG. 4 is reached, and the garbage in the input box 5 is stored in the storage box 3.

Next, when the second telescopic cylinder 15 is extended to its maximum extent, the actuating plate 9 is further pushed forward as shown in FIG. 5, and the garbage in the storage box 3 can be compressed to a high density.

By repeating the above cycle, a large amount of garbage can be compressed to a high density and stored in the storage box 3.

By the way, the same effect can be obtained even if the base and tip of the first, second, and third telescopic cylinders are replaced.

(f) Effects of the Invention As described above, according to the present invention, since the actuating plate can be pushed further forward than the opening of the input box, garbage can be stored in the storage box at a high density. , the amount of garbage that can be accommodated can be increased.
