DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a garbage pushing device for a garbage collection vehicle.

A garbage pushing container with an open front end surface is connected to a rear part of a garbage storage container with an open rear end surface, and the garbage pushing container is provided with a shielding plate for shielding an upper part of a communication part between the two containers. A device is provided, and the device pushes the garbage into the garbage storage container, and the shielding plate prevents the garbage once pushed back into the garbage pushing container, thereby increasing the pushing efficiency. is already known, but the present invention provides a button for such a device to prevent plate-like objects mixed in the garbage from getting caught in the shielding plate and to ensure its smooth operation. The purpose is to increase its strength.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 5. A garbage storage container 1 with an open rear end surface is mounted on the frame of a garbage collection vehicle, and the upper end of the rear end of this garbage storage container 1 is mounted on the frame of a garbage collection vehicle. A push-in container 2 with an open front surface is connected by a hinge pin 3 so as to be able to rotate up and down, and the inside of the garbage storage container 1 and the push-in container 2 are communicated with each other.

The push-in container 2 has an input port 4 opened at its rear, and a bottom portion 5 formed in a downwardly concave arc shape and reinforced with an appropriate reinforcing member.

The push-in container 2 houses a trash processing device that compresses and grinds the trash and pushes it into the trash storage box 1.The device will be described in detail below. A pushing plate 6 having a width so as to be in contact with the left and right inner circular surfaces of the pushing container 2 is accommodated therein, and a roller 14 is supported in a rotatable manner on a support shaft 12 provided at the base of the pushing plate 6. , these rows 214 are pushed into the container 2
The push plate 6 is fitted into a guide member 11 that is attached to both the left and right inner walls of the push plate 6 so as to be inclined downwardly toward the rear, and the base of the push plate 6 can move up and down along the guide member 11.

Located in front of the guide member 11 and above the front part of the push-in container 2, there is an upper part that extends to the full width of the push-in container 2 so as to block the upper part of the communication section between the garbage storage container 1 and the push-in container assembly. A lower shielding plate 2 is provided with a shielding plate 20 fixed substantially parallel to the guide member 11 and also extending to the full width of the push container 2.
1 is provided so as to be movable up and down with respect to the upper shielding plate 20.

As clearly shown in FIG. 2, a roller 22 is rotatably supported at both ends of the upper part of the lower shielding plate 21, and this roller 22 is fitted into the guide member 11.

Further, on the upper shielding plate 20, a plurality of protrusions 23 having a chevron-shaped cross section are arranged in parallel in the vertical direction with intervals in the horizontal direction, and on the other hand, on the lower shielding plate 21, the protrusions 23 A plurality of grooved grooves 24 having a v-shaped cross section and fitting into the grooves 23 are arranged in parallel in the vertical direction with intervals in the horizontal direction.

At the upper part of the rear end of the garbage storage container 1, a first telescopic cylinder 7 such as a hydraulic cylinder is installed at a pivot point coaxial with the hinge pin 3.
The proximal end of the first telescopic cylinder 7 is pivotally supported, and the tip of the piston rod of the first telescopic cylinder 7 is connected to a bracket 25 projecting from the lower part of the lower shielding plate 21.

Therefore, when this first telescoping cylinder 7 is telescopically operated,
The pushing plate 6 is moved up and down along the guide member 11 together with the lower shielding plate 21.

A second telescoping cylinder 8, such as a hydraulic cylinder, disposed on the outer wall of the container 2 is mounted on the bottom 5 of the push-in container 2, and its base end is pivoted on a pivot 15 so that it can swing back and forth. At the distal end of the second telescopic cylinder 8, the distal ends of two links 9 and 10 are respectively pivoted to pivot supports 8'.

The base end of one link 9 is rotatably supported by a button on a pivot 6' at the tip of the push plate 6, and the base end of the other link 10 faces the outer wall of the push container 2. It is pivotally supported on a pivot portion 16 so as to be freely rotatable forward.

An arcuate groove 17 centered on the pivot portion 16 is bored in the outer wall of the pusher container 2, and the pivot portion 8' is fitted into the arcuate groove 17.

Thus, when the first telescoping cylinder 7 is at its most contracted position and the second telescoping cylinder 8 is at its most extended position, as shown in FIG. As shown, in the position where the first telescopic cylinder 7 is the most extended and the second telescopic cylinder 8 is the most contracted, the pushing plate 6 can reach the bottom 5 of the pushing container 2.

Next, the operation process of the device of the present invention will be explained with reference to FIGS. 3 to 5. As shown in FIG.
In the state in which garbage is thrown into the interior, that is, in the state in which the push plate 6 is lifted to the upper position, the first telescoping cylinder 8 is at its minimum contraction, the second telescoping cylinder 8 is at its maximum extension position, and the lower shielding plate 21 is raised. substantially the entire surface thereof is overlapped with the fixed shielding plate 20.

(1) From this state, when the first telescoping cylinder 7 is extended and the second telescoping cylinder 8 is retracted at the same time, the pushing plate 6
The base of the press plate 6 descends backward and downward along the guide member 11 while rolling on the rollers 14, and at the same time, the tip of the push plate 6 also descends, so the push plate 6 is lowered toward the bottom 5 of the push container 2. The garbage thrown into the pushing container 2 can be compressed.

Further, the lower shielding plate 21 also descends along the guide member 11, and the communication part between the garbage storage container 1 and the pushing container 2 above the pushing plate 6 is shielded by the upper and lower shielding plates 20 and 21, and the garbage is stored in the previous step. The garbage pushed into the container 1 is prevented from returning to the pushed container 2.

After the push plate 6 is completely lowered as shown in FIG.
The telescopic cylinder 7 is set to the most contracted state of 1''!, and the first telescopic cylinder 7 is contracted.

Then, the base of the push plate 6 moves forward and upward along the guide member 11, but at this time, the tip of the second telescopic cylinder 8 is held in place by the link 10, and the link 9 is Since it rotates clockwise using the pivot point 8' with the telescopic cylinder 8 as a fulcrum, the push plate 6 connected thereto
While the tip moves forward along the bottom 5 of the push container 2, it rotates clockwise about its base as a fulcrum, gradually widening the angle it makes with the bottom 5, and presses the push plate along this process. 6 grinds the dust between the push plate 6 and the bottom 5,
It can be pushed into the garbage storage container 1.

As mentioned above, while the pushing plate 6 is pushing the garbage, the lower shielding plate 21 moves upward as the first telescopic cylinder 7 contracts and cooperates with the upper shielding plate 20 to push the button above the pushing plate 6. The front open part of the push-in container 2 can be shielded to prevent the push-in garbage from returning to the push-in container 2.

By the way, during the garbage pushing operation shown in FIGS. 3 to 5, the upper and lower shielding plates 20 and 21 for preventing the garbage from returning to the pushing container 2 move relative to each other.
A small gap is provided between these opposing surfaces in order to prevent abrasion due to mutual contact between them and to prevent an excessive load from being applied to move the lower shielding plate 21 up and down.

If this small gap is provided, a plate-like object such as cardboard paper mixed therein may enter the small gap and get caught during the dust pushing operation.

Once such jamming occurs, it becomes difficult to take out the plate-like object, and the small gap is gradually widened by the plate-like object, and the small gap gradually becomes larger, and then the plate-like objects are bitten one after another. Eventually, it becomes impossible to raise and lower the lower shielding plate 20, or the upper or lower shielding plate 20.2
However, in the present invention, this problem can be solved by the upper and lower shielding plates 20° 2 which move relative to each other.
A plurality of convex strips 2 on either one of the opposing surfaces of the
3 is provided in the vertical direction, and the protruding portion 2 is provided on the other side.
3, the plate-shaped object is prevented from entering between the upper and lower shielding plates 20 and 21.

6 and 7 show a second embodiment of the present invention,
The same members as those in the first embodiment are designated by the same reference numerals.

In this second embodiment, the upper end of the shielding plate 20 is supported on the front upper end of the push container 2 via a bracket 26 toward a pivot 27 so as to be able to swing back and forth. Guide rails 28 are formed on both sides.

On the other hand, rollers 29 are rotatably supported on both side edges of the lower shielding plate 21, and this roller 29 is fitted into the guide rail 28, and when the first telescopic cylinder 7 is operated to extend or contract,
The rollers 29 roll along the guide rails 28, and the lower shielding plate 21 moves up and down with respect to the upper shielding plate 20.

In addition, in the first and second embodiments, it is not necessary to provide only the protruding strips 23 on one of the upper and lower shielding plates 20, 21 and only the grooved strips 24 on the other. Convex and concave portions 23 and 24,! The other may be provided with recesses and protrusions 24 and 23 that fit therewith, and it goes without saying that the number, size, and spacing of the recesses and protrusions 24 and 23 can be changed as appropriate.

As described above, according to the present invention, a plurality of protrusions extending in the vertical direction are arranged in parallel on one side of the opposing surfaces of the upper shielding plate and the lower shielding plate provided on the push container, and On the other side, a concave part that fits with the convex part was arranged in parallel,
Even if plate-shaped objects such as cardboard are mixed in the garbage thrown into the push container, they will not enter the small gap between the upper shielding plate and the lower shielding plate and get stuck, and the lower shielding plate will always be connected to the upper shielding plate. The dust pushing efficiency can be improved by raising and lowering the lid smoothly and lightly with little resistance, and the strength of the upper and lower shielding plates can be increased by the concave and convex stripes.
