Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage loading device for a garbage collection vehicle.

In a so-called rear loader type garbage collection vehicle, which is equipped with a hopper having a garbage inlet on the rear surface at the rear of the body for storing garbage, and equipped with a garbage loading device that loads the garbage thrown into the hopper into the body. Conventionally, the garbage loading device used a combination of a compare panel that rotates around a shaft installed in the hopper to scrape up the garbage inside the hopper, and a ram panel that swings back and forth to push the scraped up garbage into the body. It is commonly used.

Although the above-mentioned garbage collection device has many advantages such as being easy to operate and having accurate functions, the rotation axis of the compare panel passes through the hopper, so the volume of garbage thrown into the hopper is limited. However, in recent years, a scraping panel for scraping up the dust in the hopper and pushing it into the body has been rotatably attached to another member that is attached to the upper part of the hopper so as to be able to move up and down. A so-called centerless system has been developed in which the rotation axis of the panel itself can be moved in the vertical direction.

However, with the above-mentioned centerless type, the support of the scraping panel itself moves, which inevitably makes the support unstable, causing horizontal shake, and also causes problems such as mirror-locking operation. This is done by turning the raking panel backward from the front stop position, lowering it, and rotating it forward along the bottom of the hopper. There are problems such as the garbage being pushed backwards or getting caught in the garbage near the input port when descending. It was quite difficult to set it up so that it would not occur.

The present invention solves the above-mentioned conventional problems with an extremely simple structure, and will be described below with reference to embodiments shown in the accompanying drawings.

In the figure, 1 is a body (garbage storage box) mounted on the frame of an automobile (not shown), and at the rear of the body is a hopper 2 having a garbage inlet 2' on the rear surface. It is mounted so that it can rotate.

3 is an upper panel, and a lower panel 4 for scraping dirt is connected to the lower end of the upper panel 3 so as to be rotatable about a shaft 5;
One end of the arm 6 is swingably attached to the rear upper part of the hopper 2 with a pin 7, and the other end of the arm 6 is pivotally attached with a pin 8, and the shaft 5 is attached to a guide horizontal 9 provided on the left and right side walls of the hopper 2. Guide pieces 10 such as rollers provided on both sides of the upper panel 3 are guided by the guide laterals 91 and moved downward, while the upper part of the upper panel is moved forward or forward by the rotation of the arm 6. It is designed to be able to rotate towards the body side.

Reference numeral 11 denotes a first cylinder device whose upper end is fixed to the body 1 side and whose lower end is pivotally connected to the shaft 5;
1, the upper panel 3 is guided by the guide 9 and controlled to move up and down.

Reference numeral 12 denotes a second cylinder device installed between the upper panel 3 and the lower panel 4, and the lower panel 4 can be rotated about the shaft 5 by the expansion and contraction operation of the second cylinder device 12.

13 is a deflector provided to cover the upper part of the front end of the hopper 2.

The garbage loading operation in the above configuration will be explained below.

The first cylinder device 11 contracts and the second cylinder device 12
In the extended state, the upper panel 3
is located above and its lower surface is substantially connected to the lower end of the deflector 13, and the o-a panel 4 is located above the hopper 2.
Located at the front end, the rear closing portion 1' of the body 1 is closed by the deflector 13, upper panel 3, and lower panel 4 to prevent the garbage inside the body 1 from falling into the hopper 2. This state is maintained while driving.

When collecting dust, first the second cylinder device 12 is contracted, and the lower panel 4 is turned backward about the shaft 5 as shown in the chain diagram in FIG.

Next, the first cylinder device 11 is extended. Then information piece 1
0 is guided by the guide lateral 9 and moves downward, but at this time, the arm 6 rotates downward around the pin 7 and pushes the upper part of the upper panel 3 forward via the pin 8, thereby pushing the lower part of the deflector 13. Press the garbage against the body 1 side. The lower panel 4 also moves downward due to the downward movement of its pivot point 5, but at this time, as the upper part of the upper panel 3 moves forward as described above, the upper pivot point of the second cylinder device 12 also moves forward. Therefore, the lower panel 4 detours backward, that is, toward the input port 2' side, as shown by the arrow x in FIG.
It descends in a trajectory as if it is being scratched inwards, and reaches a point where its tip is located near the rear end of the arcuate bottom surface 2a, as shown by the solid line in FIG. Next, when the second cylinder device 12 is expanded. The panel 4 rotates forward along the arc-shaped bottom surface 2a, scrapes the input garbage from this section onto the rising bottom surface 2b in front, reaches the position shown in FIG. 3, and then contracts the first cylinder device 11. As a result, the lower panel moves upward as the upper panel 3 rises, scooping up the thrown-in garbage and pushing it into the body until the state shown in FIG. 1 is reached, and one cycle of including the garbage is completed. In addition, 14 in Figure 1
is a dump stopper provided near the lower end of the guide lateral 9, and after the dump stopper 4 is rotated from the storage position, which is deviated by the guide lateral 9 shown by the solid line, to the use position located on the guide lateral 9, When the first cylinder device 11 is extended, the guide piece 5 hits the top surface of the dump stopper 14 on its way down, and as the first cylinder device 11 is further extended, the hopper 2 is dumped upward rearward centering on part A, and the body The rear opening 1' of the body 1 is opened to discharge dust inside the body 1. As described above, according to the present invention, the lower panel for scraping dirt has a structure in which its ball portion is guided and supported next to the guide side of the hopper side wall, so that the support is very reliable and there is no left or right wobbling. This allows for stable operation. In addition, since the upper part of the upper panel is pivoted to the front end of an arm pinned to the upper rear part of both side walls of the hopper, the upper part of the upper panel moves forward as the upper panel descends, and the debris inside the body is moved into the hopper. At the same time, the lower panel takes a trajectory that detours around the garbage inlet from the inverted position and descends in such a manner as to scrape inside the garbage at the inlet, scraping out the input garbage to the rear. There are no encroaching rips, and the loading operation can be carried out accurately.This, combined with the simple construction, can bring about great practical effects.
