Description

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

In the so-called rear loader type garbage collection vehicle, which has a hopper for loading garbage at the rear of the pode that stores garbage, and is equipped with a loading device such as a rotating plate and a pushing plate in the hopper,
Conventionally, a portion of the hopper is generally rotated upward relative to the body to open the rear part of the body so that the garbage stored in the body can be discharged.

In the case where a part of the hopper is installed at the rear of the hopper so that it can be opened and closed, it is extremely difficult to completely prevent sewage in the body from leaking from the joint between the body and part of the hopper. However, there is a drawback that sewage flows down the road while driving in the city, and when a part of the hopper is dumped when discharging dust, the hopper part that was accidentally dumped may fall, resulting in death or injury to workers, which is extremely dangerous. Dangerous, etc.
It has many problems.

In order to deal with the above-mentioned problems, a garbage collection vehicle with a rear loader type garbage collection vehicle in which a part of the hopper is integrally formed at the rear of the body as an extension of the body has been considered. In a type garbage collection vehicle, when the garbage compressed and stored in the body is discharged from the entrance part behind a part of the hopper, the garbage accumulates in the garbage input recess of the hopper, and the garbage accumulated in the recess is not left behind. It is extremely difficult to expel the liquid.

The present invention provides a dust discharge device that can follow the bottom surface of any shape of a body or a part of a hopper and can discharge all dust in one operation, and will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a body (garbage storage box) mounted on the frame of an automobile, and a hopper part 2 having a closing part for inputting and discharging garbage is integrally connected to the rear of the body.

Reference numeral 3 denotes a dust ejecting device according to the present invention. The ejecting device 3 is attached to the upper part of the body 1 so that one end can be rotated up and down on the chest 8, and the other end is positioned above the rear of the body 1 by a spring 7. A discharge panel 5 is rotatably attached to the rear end of the link 4 by a shaft 9, and one end is pivoted to the upper front end of the body 1, and the other end is supported so as to maintain a substantially horizontal state. It is constituted by a combination of a cylinder device 6 pivotally attached to a discharge panel 5.

When the cylinder device 6 is in a contracted state, the link 4 is moved by the spring 7 so that its tip is located at the rear upper part of the body 1.
The discharging panel 5 is supported with its tip close to the upper part of the front wall of the body, and the entire garbage discharging device 3 is located at the storage position 1 along the upper part of the podium 1 as shown by the solid line in the figure. Retained.

The hopper part 2 includes a guide rail 11 which is pivotally attached to the front upper part of the hopper part 2 by a shaft 17 and can rotate along the left and right side walls of the hopper part 2, respectively. A slider 2 is mounted on the slider 2, and an axis 1 is attached to the slider 2.
A scraping panel 13 is rotatably mounted at 8, an inside cylinder device 14 for controlling the rotation of the scraping panel 13 with respect to the slider 12, and one end of the scraping panel 13 is attached to the rear part of the side wall of the hopper by a pin 19. A garbage loading device 10 is provided, which includes a rotary arm 15 that is rotatably attached and whose other end is pivotally connected to the ball 18, an outside cylinder device 16 that controls the rotation of the rotary arm 15, and the like. 2
This is a deflector fixed to the guide rails 11 on the left and right sides of the river.

When discharging the garbage in the garbage loading device 1 and the body 1, the outside cylinder device 16 is extended as shown in the figure to position it above the hopper part 2, so that the rear closed part of the hopper part is completely covered. Normally, it is located inside the hotspot 2, and the rotation of the scraping panel 13 due to the operation of the inside cylinder device 14 and the sliding movement of the slider 2 due to the operation of the outside cylinder device 16 are controlled. In combination, the dust thrown into the recessed part 2a of the hopper part 2 from the rear is scraped up and pushed into the body 1.

However, since the garbage loading operation performed by the loading device 1 has no direct relation to the present invention, a detailed explanation will be omitted. When discharging dust, when the dust filling device 10 rotates upward to fully open the rear opening as described above, the cylinder device 6 of the discharge device 3 begins to extend. Then, the discharge panel 6 rotates around the shaft 9, and its tip moves downward along the arcuate front wall surface la of the body until it reaches 0'. In this case, the reaction force of pushing out the dust inside the body 1 acts in a direction to force the link 4 upwardly through the shaft 9, but the spring 7
If the spring force is set sufficiently large, the position of the shaft 9 will hardly move. Further, the arc of the front wall la of the body 1 may be appropriately set in consideration of the fact that the shaft 9 moves slightly upward. When the cylinder device 6 is further extended from the position B, the tip of the discharge panel 5 is located at the bottom surface lb of the body 1.
At this time, the discharge panel 5 continues to move backward from M to the W position while pushing up the link 4 via the shaft 9, pushing out the garbage and reaching the position V at the front end of the hopper section 2. When the cylinder device 6 continues to expand further, the link 4 rotates downward due to the spring force of the spring 7, and the tip of the discharge panel 5 rotates backward while descending along the bottom surface 2b of the recess 2a of the hobber part 2. From this position, the hopper part 2 reaches a skin position at the rear end of the hopper part 2, and all the dust in the recessed part 2a of the hopper part 2 is discharged to the outside.

When the cylinder device 6 contracts, it returns to the original storage position 1, completing the dust evacuation cycle.

In the figure, reference numeral 21 denotes a shielding plate.The shielding plate 21 is rotatably attached to the upper part of the joint between the body 1 and the hopper part 2 by means of a shaft 22, and a rotational force is applied in the clockwise direction in the figure by a spring or the like (not shown). The tip of the discharge panel 5
The body 1 is in contact with the rear lower surface thereof, and the upper part of the body 1 behind the shaft attachment point 9 of the discharge panel 5 is closed, thereby preventing dust from protruding from the upper part of the body 1. The shielding plate 21 is pushed and rotated rearward as the discharge panel 5 performs the discharge operation.
Also, following the return of the discharge panel 5 to the front upper part, it returns to the solid line position at the front upper part. As described above, according to the present invention, the position of the discharge panel is restricted by a spring, and the discharge panel is equipped to be rotatable in the front and rear directions via a link, and a cylinder device for rotating the discharge panel rearward is provided, which is extremely simple. With this configuration, all the dust in the body and hopper can be accurately discharged, and the cost is low, and the practical value is extremely great. It goes without saying that the garbage loading device is not limited to the one shown in the illustrated embodiment, but that the present invention can be applied to any type of garbage loading device that can move to open the rear closing part when discharging garbage. Furthermore, the present invention can also be applied to conventional garbage collection vehicles that can dump a portion of the hopper onto the body.
