Description

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

In a garbage loading device for a garbage collection vehicle in which a tailgate is pivotally attached to an opening of a loading box that accommodates garbage, the tailgate is closed when loading garbage, and the loading mechanism therein is operated. The tailgate is designed to rotate up and down when removing trash from the cargo box. However, in this type of garbage loading device, the tailgate, including the bottom sump section and side plates, is quite large and heavy, and it is difficult to rotate it upward with a dump cylinder etc. to discharge the garbage. Considerable power is required, and due to the large weight there is a risk that the tailgate will fall from its raised position.

Furthermore, the sump part of the tailgate is constructed integrally with the side plate, and each time the tailgate is opened, the sump part separates from the lower edge of the cargo box opening part. Sewage in the garbage tends to leak at the joint of the box opening. The present invention aims to solve the above-mentioned safety and hygiene problems of the known technology.

Next, embodiments of the present invention will be described with reference to the drawings. 1st
In the figure and Fig. 2, 1 is the packing box of the garbage collection truck.
Dust is collected inside this.

Both side walls 1a of the packing box 1 extend rearward and downward from the opening at the rear end of the packing box to form extended side plates 2, and the bottoms of these side plates 2 are connected integrally by a bottom plate 3. connected. The bottom plate 3 is integrally connected to the floor lb of the cargo box 1 and curved downward from the floor lb to form a sump section 4 for garbage. The lower portions of both side plates 2 are integrally connected by a connecting member 5 at the rear edge of the bottom plate 3. A profile 6 is fixed to the upper part of the opening of the cargo box 1, and the upper end of the side plate 9a of the tailgate 9 is pivotally connected to a bracket 7 fixed to the container by a pivot 8.

The left and right tailgate side plates 9a are formed short so as not to reach the sump part 4, and are connected and integrated by a connecting member 10.

Further, portions of the left and right tailgate side plates 9a near the cargo box opening are connected to a panel-shaped deflector 11 in a saw-like manner. The tailgate side plate 9a is in contact with the inside of the side plate 2 of the sump portion 4 in the tailgate closed position shown in FIG. On the inner surface of the tailgate side plate 9a,
A guide rail 13 having a U-shaped cross section along the deflector 11
is fixed almost vertically.

On the other hand, a slide panel 14 is located between the guide rails 13 on both sides, and a protrusion 15 fixed to the outside of the frame member 14a (FIG. 1) on both sides of this slide panel is inserted into the groove of the guide rail 13. It is fitted so that it can slide up and down. Therefore, the slide panel 14 can be moved up and down while being guided by the guide rail 13. Brackets 17 are fixed to the member 16 that integrally connects the tailgate side plate 9a to the upper part, and the pivot shaft 1 of these brackets 17
The upper end of the vertically movable cylinder device 19 is pivotally mounted by 8, and the lower end of the piston rod of the vertically movable cylinder device 19 is fixed to the bracket 2? It is pivotally connected to by a pivot 21.

Therefore, the slide panel 14 is lowered by the extension of the vertically movable cylinder device 19. A scraping panel 24 is pivotally attached to the lower edge of the slide panel 14 by a pivot 23.

The scraping panel 24 is composed of two panel parts 24a and 24b that protrude at an angle to each other. Ru. The upper end of the raking cylinder device 28 is pivotally attached to the pivot 27 of the bracket 26 provided near the upper end of the slide panel 14, and the lower end of the piston rod of the raking cylinder device 28 is attached to the rear surface of the panel portion 24b by the pivot 29. It is pivoted. Therefore, the scraping panel 24 rotates around the pivot 23 as the scraping cylinder device 28 expands and contracts. A lower end of a cylinder device 32 is pivotally attached to a bracket 30 attached to the side of the cargo box 1 by a pivot 31.
and its upper end is connected to the upper part of the tailgate side plate 9a by a pivot 33.
It is pivoted by.

Note that 34 is a locking member that fixes the tailgate side plate 9a to the sump section side plate 2. In the above configuration, in order to load garbage, the scraping cylinder device 28 is contracted in the state shown in FIGS. 1 and 2.

This causes the scraping panel 24 to flip counterclockwise around the pivot 23 as shown by arrow A in FIG. Next, by expanding the vertically moving cylinder device 19,
The scraping panel 24 descends as shown by arrow B while remaining in an inverted state, and the tip of the panel portion 24 reaches near the entrance of the sump portion 4. Next, the scraping cylinder device 2
8, the scraping panel 40 rotates as shown by arrow C, and the panel portion 24a scrapes the garbage dumped onto the sump portion 4. Next, the vertically movable cylinder device contracts, and the scraping panel 24 rises as shown by arrow D, scraping up the garbage into the load/box 1. To discharge the garbage collected in the cargo box 1 as described above, the lock member 34 is unlocked and the dump cylinder device is extended.

As a result, the tailgate 9 rotates around its pivot 8 as shown by arrow E in FIG. 31 and assumes the position shown in the figure. Next, when the raking cylinder device 28 is retracted, the raking panel 24 is reversed to the position shown in FIG. 3 where it does not interfere with ejection. In this state, a known discharge plate 36 (Fig. 3), which has been retracted deep inside the cargo box 1, is moved forward to the opening of the cargo box by the action of a hydraulic device (not shown) to remove the garbage inside the cargo box. Discharge outside.

The advanced position of the ejector plate 36 is shown in phantom in FIG.
Due to this discharge action, a certain amount of dust remains in the sump section 4. In order to discharge this, after retreating the discharge plate 36 to the back of the cargo box 1, the raking cylinder device 28 is extended to return the raking panel 24 to the raking position, the gump cylinder device 32 is retracted, and the tailgate 9 lower it and lock it with the locking member 34. Next, after extending the vertical cylinder device 19 and lowering the raking panel 24, the raking cylinder device 28 is contracted and the raking panel 24 is reversed as shown by arrow F in FIG. The remaining debris is pushed out of the sump.

After all the dust has been discharged as described above, the raking panel 24 is returned to its original raking position, and the raking panel 24 is raised as shown by arrow G by the contraction of the vertical movement cylinder device 19. Finish the operation. Fourth
In the embodiment shown in the figure, the side plate 2 of the sump part 4 is initially removed to a fairly low position as shown at 2a, and a member 37 with holes for actuating the locking member 34 is inserted upwardly from the upper edge 2a of the side plate 2. It's made to stick out.

In the present invention, the embodiments of which have been described above, the bottom of the tailgate is opened to reduce the weight of the tailgate, and instead, the sump section that functions as a tailgate sump is integrally connected to the vehicle body such as a cargo box. As a result, it is possible to reduce the weight of the tailgate itself while still fulfilling the functions of the conventional tailgate-type garbage loading device, thereby reducing the output required for operating the tailgate and reducing the risk of the tailgate falling.

Furthermore, since the sump section that functions as a tailgate sump is immovably connected to the cargo box, leakage of waste liquid can be completely prevented.
