Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage vehicle in which a tailgate equipped with a garbage loading device is pivotally mounted on the top horizontal member of the rear end opening of the cargo box.

In such garbage trucks, the loading device compresses the garbage against the top plate of the cargo box, so during the rainy season and summer, the garbage sticks to the top of the cargo box due to the adhesive force of the wet garbage, causing the load to become In some cases, it may be difficult to discharge the garbage smoothly simply by tilting the box.To enable operation in incinerator facilities with low ceilings or narrow alleys, some or all of the top horizontal members may be moved from the bottom surface of the top plate of the cargo box. This tendency is remarkable when the vehicle height is lowered by protruding downward.

In order to solve this problem, the present invention has an opening in the top plate of the cargo box just in front of the top horizontal member, a rear end of the ejection auxiliary plate that constantly closes the opening, and a lever that moves the ejection auxiliary plate up and down. is pivoted to the top horizontal member, and between the input side terminal of the lever and a tailgate side hinge metal fitting pivoted to the top horizontal member, an ejection auxiliary plate can be pressed down in conjunction with opening of the tailgate. By attaching a toggle joint and setting the dead center of the toggle joint to approximately the half-open position of the tailgate, the discharge auxiliary plate can be rotated in conjunction with the tailgate so as to push out the full garbage in the cargo box while the tailgate is open. Moreover, when the opening of the tailgate is completed, the discharge auxiliary plate automatically returns to a position where it does not interfere with the discharge of dirt.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a loading box whose rear end is pivoted on a shaft 3 so as to be tiltable rearward on the automobile body 2; 4 denotes a top horizontal member fixedly protruding downward from the rear end opening top plate 5 of the loading box; 6; 7 indicates a bracket for pivoting the tailgate fixed to the top horizontal member 4; 7 indicates a hinge fitting of the tailgate 9 pivoted by a shaft 8 between the brackets 6 and 6 on both sides; , there is an opening 5 bored in the top plate 5 of the cargo box almost adjacent thereto.
The rear end of the ejection auxiliary plate 10 that closes the a is pivoted by a shaft 11.

The ejection auxiliary plate 10 has a width slightly smaller than the horizontal length of the top horizontal member 4, and has an arc-shaped closing plate 10a centered on the pivot shaft 11 at its front end, and an inner wall of the cargo box 1 on both sides. Side plates 10b which are in substantially sliding contact with each other are fixed to each other, and the arcuate closing plates 10a, together with the ejection auxiliary plate 10, always close the opening 5a regardless of whether the ejection auxiliary plate moves up or down.

Reference numeral 12 denotes a bell crank-shaped lever that moves the ejection auxiliary plate 10 up and down.The base of the lever 12 is pivotally mounted 13 between the brackets 6 and 6 on both sides, and its output end is connected to the ejection auxiliary plate 10 via a link 14. connected to.

Reference numeral 15 denotes an arm provided on the tailgate side hinge fitting 7 so as to protrude upward from the pivot shaft 8, and the arm 15 and the input side end of the lever 12 are connected by a link 16.

The link 16 cooperates with the arm 15 to form a toggle joint whose dead center O is located at the tailgate 9.
is set to the half-open position.

Therefore, when the tailgate 9 is closed with respect to the cargo box 1 as shown in FIG. 2, and when the tailgate is opened as shown in FIG. 3, the connecting shaft 17 between the arm 15 and link 16 is As shown by the dotted line and the solid line in FIG. 3, the ejection auxiliary plate 10 assumes the same position at a symmetrical position below the road with respect to the dead center O.

As shown in FIG.
It is equipped with a rotary plate 19 that is rotated, and a push plate 22 that is swung back and forth by a hydraulic cylinder 21 about a shaft 20, and the base end of the hydraulic cylinder 21 is connected to the top horizontal member 4,
As before, it is also used as a tailgate opening/closing cylinder.

The illustrated hinge fitting 7 is attached to the upper bulkhead plate 2 in the tailgate.
It is integrated with 3.

Loading box 1 by garbage loading device 19.22 inside the tailgate
When discharging the compressed garbage, first extend the hydraulic cylinder 21 and move the tailgate 9 to the position indicated by the chain line A in FIG.
When the tailgate begins to rotate upward about the shaft 8, the arm 15 moves to the link 16.
The lever 12 is rotated counterclockwise via the lever 12 to begin to push down the dust discharge auxiliary plate 10.

That is, as the rear end opening 1b of the cargo box 1 opens, the ejection auxiliary plate 10
Since this presses down the garbage, the built-in garbage near the rear end collapses and is discharged, creating a space in the rear upper part of the seedling box.

Toggle joints 15 and 16 as the tailgate rises
When the connecting shaft 17 of the tailgate reaches the dead center O, the ejection auxiliary plate 10 descends to the position shown by the chain line in FIG. When the ejection auxiliary plate 10 starts to be pulled up and the tailgate 9 is fully opened as shown in FIG. 3, the lever 12 and the ejection auxiliary plate 10 return to the same position as when the tailgate is closed.

Therefore, if the packing box 1 is tilted rearward about the pivot shaft 3 as shown by the chain line B in Figure 1, a space is formed at the rear upper part of the packing box, so that the garbage inside the packing box can be removed. It is smoothly discharged from the rear end opening 1b by the action of gravity.

In the illustrated embodiment, the arc-shaped closing plate 10a is provided at the tip of the ejection auxiliary plate 10, so that the notch 5a is closed regardless of whether the ejection auxiliary plate 10 moves up or down, and the ejection auxiliary plate 10 and the top plate 5 are closed.
This is to prevent dust from entering between the top horizontal member 4.
protrudes downward from the lower surface of the top plate 5 and is fixed to the top horizontal member 4.
The reason why the discharge auxiliary plate 10 is mounted on the pivot 11 at the lower front end of the seedling box is to lower the vehicle height and eliminate the possibility that the garbage will get caught on the top horizontal member 4 when the garbage inside the seedling box is being discharged. It's for a reason.
