Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a garbage pushing device provided in a garbage processing frame at the rear of a garbage storage box, so that garbage thrown into the garbage processing frame can be efficiently accommodated in the garbage storage box. The present invention relates to a garbage collection vehicle, in which the garbage inlet can be provided at a low position to facilitate the input of garbage and to prevent the garbage from returning.

Embodiments of the present invention will be described below with reference to the drawings.1
is a garbage storage box, the lower end of which is pivoted 3 on the chassis 2, and is configured so that it can be tilted rearward using the pivot 3 as a fulcrum by a hydraulic cylinder (not shown).

Further, a garbage processing frame 4 is rotatably supported 5 at the upper end of the garbage storage box 1, and a garbage inlet 6 is opened at the lower back surface of the processing frame 4, and a garbage inlet 6 is opened at the lower part of the processing frame 4. A storage chamber 7 is formed, and the garbage input from the input port 6 is stored in the voice storage chamber 7.
stored within.

The garbage processing frame 4 is equipped with a garbage pushing device.The configuration of this device will be explained below.A telescopic device 8 is installed above the garbage processing frame 4, and this The upper part of the outer frame 10 is rotatably supported 9 on the ceiling wall of the garbage processing frame 4, and the inner frame 11 is slidably fitted into the outer frame 10. The inner frame body 11 expands and contracts by the operation of an internally installed hydraulic cylinder 12.

On the other hand, a scraping plate 13 is provided at the tip of the inner frame body 11, and the scraping plate 13 is pivoted 15 times by the expansion and contraction of a hydraulic cylinder 14 installed between the back surface of the scraping plate 13 and the inner frame body 11. The scraping plate 13 and the hydraulic cylinder 14 move together with the inner frame 11 as the hydraulic cylinder 12 expands and contracts.

Further, a hydraulic cylinder 16 is installed between the rear upper part of the garbage storage box 1 and the outer frame 10, and as the hydraulic cylinder 16 expands and contracts, the outer frame 10 can rotate around the pivot 9. It is composed of:

Note that the hydraulic cylinder 16 may also be used for raising and lowering the five pivot parts of the garbage processing frame 4 by appropriately securing the rotation of the outer frame body 10 around the pivot parts 9. .

Reference numeral 17 denotes a shielding plate for shielding the hydraulic cylinder 16 from dust.

Next, the operating process of the embodiment of the device of the present invention will be explained with reference to FIG. 2. First, the hydraulic cylinder 16 is extended from the pushing end position shown in FIG. When this happens, the outer frame 10 rotates counterclockwise nine times on the pivot and returns to the rearward opening position (Fig. 2b).
.

Thereafter, the hydraulic cylinder 16 is stopped at the extended position to hold the outer frame 10 in that position, and then the hydraulic cylinder 14 is retracted, and the scraping plate 13 rotates counterclockwise to move to the position shown in FIG. 2C. Operate.

Next, the hydraulic cylinder 14 is stopped at the retracted position and the scraping plate 13 is held at that position, and in this state, the hydraulic cylinder 1
2, the scraping plate 13 descends substantially vertically as the inner frame body 11 moves, reaches the upper part of the garbage thrown into the storage chamber 7, and compresses the garbage, as shown in FIG. 2d. become.

After the scraping plate 13 reaches the lowered position, the hydraulic cylinder 1
4 is extended and the scraping plate 13 is rotated clockwise to scrape up the dirt in the storage chamber T onto the scraping plate 13 (Fig. 2e).

After that, when the hydraulic cylinder 12 is operated to retract while the hydraulic cylinder 14 is held in the extended position, the scraping plate 13 is moved to the inner frame 11 while keeping the dirt scraped up on the scraping plate 13.
2, and the state shown in FIG. 2f is reached.

Next, when the hydraulic cylinder 16 is operated to contract, the outer frame 10
At the same time, the dust accumulated on the scraping plate 13 is pushed into the storage box 1, returning to the state shown in FIG. 2a, and one cycle of dust pushing is completed.

As described above, according to the present invention, after the garbage in the storage chamber is scooped up by the pushing device, it is raised and further pushed into the garbage storage box. The garbage inlet can be provided at a low position, which facilitates the garbage input operation and prevents the garbage from returning from the garbage storage box to the garbage processing frame.

In addition, since the raking plate of the pushing device moves up and down in parallel on a straight track, the dirt on the raking plate is held stably, and there is no spillage of dirt from the raking plate while it is being raised, and the rotation of the raking plate is Since the drive device is provided between the expansion and contraction device and the raking furnace, the drive device can be attached separately from the garbage processing frame, making it easy to manufacture.

[Brief explanation of the drawing]

FIG. 1 is a partially cutaway side view of the garbage collection vehicle of the present invention, and FIG. 2 is an operational diagram showing the garbage processing process. 1 is a garbage storage box, 4 is a garbage processing frame, 6 is an input port, 7 is a storage chamber, 8 is an expansion/contraction device, and 13 is a scraping plate.

Claims (1)

[Claims] 1. A garbage processing frame that is connected to the rear opening of the garbage storage box and has a garbage inlet and a storage chamber formed below, and a garbage pusher that supplies the garbage in the storage chamber to the storage box. The dirt pushing device has a scraping plate housed in the processing frame, a first drive device that moves the scraping plate up and down on a linear trajectory, and a scraping plate that moves the scraping plate up and down on a straight track. a second driving device disposed between the plates and rotating the scraping plate; and a third driving device rotating the first and second driving devices and the scraping plate further inward of the storage box. Garbage pushing device such as Toyoshi Naru garbage collection truck.
