Description

[Detailed description of the invention] The present invention relates to a garbage collection vehicle.

Conventionally, in a so-called rear rotor type garbage collection vehicle, which has a hopper for loading garbage at the rear of the body that accommodates garbage, and is equipped with a loading device such as a rotating plate and a pushing plate inside the hopper, the hopper part is It is generally designed to rotate upward relative to the body to open the rear part of the body so that the garbage stored within the body can be discharged. In the case where the hopper is provided at the rear of the body so that it can be opened and closed, it is extremely difficult to completely prevent the wastewater in the body from leaking from the joint between the body and the hopper.
There is a drawback that sewage flows down the road while driving in the city, and when the hopper is dumped when discharging dust, the hopper may accidentally fall and cause death or injury to workers, which is extremely dangerous. etc., there are many problems. In order to deal with the above-mentioned problems, a rear rotor type garbage collection vehicle is being considered in which the hopper is integrally formed at the rear of the body as an extension of the body. The mechanism for loading the garbage into the body and the mechanism for discharging the garbage from the body have extremely complicated structures and are quite cumbersome, so they have not yet been put into practical use. The present invention provides a device for loading and discharging garbage with a simple structure and with good functionality in a rear loader type garbage collection vehicle in which the hopper part is integrally formed at the rear of the body as described above. The embodiments shown in the accompanying drawings will be described below. In Figure 1, 1
1 is a body (a garbage storage box) mounted on a frame of an automobile (not shown), and a hopper section 2 having a garbage input port on the rear side is integrally connected to the rear of the body. Reference numeral 3 designates a scraping panel, and the scraping panel 3 is held so as to be slidable on a guide rail 5 rotatably pivoted by a pin 7 along the inner surfaces of both left and right walls at the rear upper part of the body 1. A bracket 4 is attached to the lower end of the slider 4 so as to be rotatable about a shaft 6, and is fixed to the slider 4.
The scraping panel 3 can be controlled to rotate about the shaft 6 by expanding and contracting a first cylinder device 8 whose both ends are pivotally connected between the bracket 3a and the bracket 3a fixed to the scraping panel 3.

Reference numeral 9 denotes a deflector integrally constructed to connect the left and right guide rails 5, and the deflector 9 and the scraping panel 3 move the body 1 at the garbage loading completion position as shown by the solid line in FIG. The rear part of the body 1 is closed to prevent dust from falling into the hopper part 2.

Reference numeral 10 denotes an arm having one end pivotally attached to the shaft 6 and the other end pivotally attached to the side wall of the hopper section with a pin 11;
0 rotates up and down around the pin 11 by the expansion and contraction operation of the second cylinder device 12 (provided on the outside of the side wall of the hopper part), and slides the slider 4 through the shaft 6, while the scraping panel is moved. 3. The guide rail 5 and the deflector 9 etc. provided integrally therewith can be rotated up and down around the pin 7.

13 is a cylinder device 12 provided on the side wall of the hopper section 2
This is an escape slot for the pin 12a that connects the arm 10 to the pin 12a.

In the above configuration, when garbage is put into the hopper section 2 as shown by the arrow A in the state shown by the solid line in FIG. The scraping panel 3 rotates rearward about the shaft 6 and enters the state shown by the chain line. Next, the second cylinder device 12 contracts and the arm 10 pivots downward about the pin 11.

Then, the slider 4 slides downward, and the shaft 6 moves as shown in Fig. 2.
reaches a position near the center of the arcuate surface of the bottom surface of the hopper section 2, which is substantially arcuate in the front-rear direction, and the tip of the scraping panel 3 is located near the rear end of the arcuate bottom surface of the hopper section 2. In this state, the cylinder device 8 then expands and contracts.

Then, the scraping panel 3 rotates forward about the shaft 6, and scrapes the garbage thrown into the hopper 2 forward.
When the scraping panel 3 rotating along the bottom surface of the hopper 2 reaches the position shown by the chain line in FIG. 2, the cylinder device 8
At the same time as the extension operation of the cylinder device 12 stops, the other cylinder device 12
starts to extend, the arm 10 rotates upward while sliding the slider 4 upward, the scraping panel 3 rotates around the pin 11, and the scraped input garbage is transferred to the body 1.
One cycle of the loading operation is completed when the load reaches the state shown in FIG. 1.

During the above operation, the rotational displacement of the deflector 9 fixed to the guide rail 4 around the pin 7 is extremely small, and the deflector 9 continues to take a position that closes the rear part of the body, so that the dust inside the body is prevented during the loading operation. It will not overflow into the hopper.

When discharging the dust inside the pod 1, first, the first cylinder device 8 is retracted from the stop position shown by the solid line in FIG. 1, and the scraping panel 3 is rotated backward as shown by the chain line.
The second cylinder device 12 is extended and rotated upward until the deflector 9 is in a substantially horizontal position as shown in FIG. Then, the rear part of the body 1 is completely opened, and the ejector panel 1 is guided inside the body 1 by a rail 15 and is equipped to move in the front and rear direction by a third cylinder device 16.
4 is moved rearward as shown by the chain line by the extension operation of the cylinder device 16, the dust in the body 1 is forcibly discharged from the rear of the hopper section 2.

To remove the dust remaining in the recess on the bottom of the hopper section 2, move the ejector panel 14 forward and return the scraping panel 3 to the state shown by the solid line in Figure 1, contrary to the loading process. First, the second cylinder device 12 is contracted, and then the first cylinder device 8 is contracted to rotate the scraping panel 3 in the opposite direction along the bottom surface of the hopper section 2 to scrape out.

The forcible ejection mechanism using the ejector panel 14 described above is the same as that conventionally used in general saws, so a detailed explanation will be omitted.

As described above, according to the present invention, there is provided a guide rail which is pivotally mounted above the rear part of the body and has a deflector integrally provided thereon, and a slider which is slidably attached to the guide rail.
a scraping panel rotatably pivoted to the slider;
and a rotating arm that supports the slider, and a first cylinder device for controlling the rotating movement of the scraping panel with respect to the slider, and a first cylinder device for controlling the sliding movement of the slider and the slider and the guide through the rotating arm. By the combination of the operation of the second cylinder device that controls the vertical movement of the rail, etc., at the stop position of these devices, the rear part of the body is closed by the deflector and scraping panel provided on the guide rail, and the inside of the body is closed. This prevents the garbage from falling into the hopper, and when loading the garbage into the hopper, the deflector hardly moves from the position where it closes the rear of the body, and the hopper is moved by operating the scraping panel while holding down the garbage inside the body. The internal dust can be pushed into the body, and when the internal dust is to be discharged, the second cylinder device is activated to rotate the entire device upward to completely open the rear part of the body, allowing the ejector panel to discharge the dust. It is extremely effective in that it is possible to load and discharge garbage in a garbage collection vehicle having a hopper integrally formed at the rear of the body in a functional and accurate manner.

Further, according to the present invention, the rotation fulcrum of the scraping panel is provided on the slider that slides up and down, and the sliding and rotation of the slider is controlled via the arm. It has the advantage that the specified operation can be performed by relatively small stroke operation of each of the first and second cylinder devices, and the space in the hopper section for throwing in the trash can be sufficiently large, making the task of putting in the trash very easy. ing.

Furthermore, when operating these devices, the scraping panel is not located above the garbage inlet, and all operations are performed inside the hopper, so there is no danger to workers, and there is no risk of rainwater entering the hopper. It has a very good practical structure, as it does not interfere with operation even if a cover (roof, rear door, etc.) is installed to prevent the infiltration of water.
