Description

[Detailed description of the invention] Industrial application field This invention is a compression type garbage collection vehicle used for collecting bulky garbage, etc., in which garbage adheres to a shielding plate installed between a garbage storage box and a garbage input box. This invention relates to a device that prevents

BACKGROUND TECHNOLOGY In general, a compression type garbage collection vehicle, as shown in Fig. 1, temporarily stores garbage thrown in through a garbage storage box 1 (hereinafter simply referred to as storage box) and an input port 2 provided at the rear. It has a garbage input box 3 (hereinafter simply referred to as the input box). A discharge plate 5 is installed inside the storage box 1 so as to be slidable in the longitudinal direction of the vehicle body 4, and this discharge plate 5 is slid by the expansion and contraction operation of a discharge cylinder 6 attached to the front part of the storage box 1. . Further, the input box 3 is attached to the rear end opening of the storage box 1 so as to be rotatable about the upper end of the opening as a pivot.
The rear end opening of the storage box 1 is opened and closed by the input box 3 by the expansion and contraction operation of the opening/closing cylinder 7 provided at a predetermined position. Incidentally, upper and lower movable plates for loading the thrown garbage into the storage box 1 are arranged in the above-mentioned input box 3. FIG. 2 shows the basic (initial) position of the upper and lower actuating plates, and as shown in the figure, the upper and lower ends of the upper actuating plate 8a are free of the two support arms 9, 9 that are supported at different rotation centers. connected to the end. This upper actuating plate 8a is used for telescopic operation of a first telescopic cylinder 10a whose base end is pivotally attached to the bottom of the input box 3 and whose rod tip is rotatably attached to the upper end of the upper actuating plate 8a. performs the prescribed operation. Further, the lower actuating plate 8b is rotatably attached to the lower end of the upper actuating plate 8a,
Furthermore, the base end is pivotally connected to the upper end of the upper actuating plate 8a,
Further, a predetermined operation is performed by the telescopic operation of the second telescopic cylinder 10b, the tip of which is rotatably attached to the protrusion on the rear surface of the lower operating plate 8b. Further, a shield plate 11 is fixed to the upper end of the input box 3 between the storage box 1 and the input box 3, and shields the upper half of the rear end opening of the storage box 1. This prevents the garbage loaded into 1 from returning.

Therefore, when the garbage 12 is charged from the input port 2 provided in the input box 3 with the upper and lower movable plates 8a and 8b in the basic position shown in FIG. Due to the contraction operation, the lower actuating plate 8b rotates counterclockwise by a predetermined angle and stops (see FIG. 3). In this state, the first telescopic cylinder 10a performs a contracting operation, causing the upper and lower actuating plates 8a, 8b to descend, and when they reach a certain position, the second telescopic cylinder 10b performs an extending action at the same time as the first telescopic cylinder 10a contracts. The lower actuating plate 8b begins to rotate clockwise [4th
See figure]. Due to the downward pressing force of this lower actuating plate 8b, the dust is compressed between the lower actuating plate 8b and the bottom inner wall of the input box 3, and the first telescopic cylinder 10a is compressed to the minimum as shown in FIG. ,and,
When the second telescopic cylinder 10b is extended to a predetermined length and the upper and lower actuating plates 8a and 8b are arranged substantially in a straight line, the first telescopic cylinder 10a is extended and the upper and lower actuating plates 8a,
8b rises diagonally forward and moves to the basic position shown in FIG. 2, and the compressed garbage 12 is loaded into the storage box 1. The above is one cycle of operation of the upper and lower operation plates 8a and 8b during loading operation, and the garbage 12
The upper and lower actuating plates 8a, 8b each time the
performs the above-mentioned one-cycle operation, the garbage 12 is sequentially loaded into the storage box 1, and when the garbage in the storage box 1 is full, the loading operation is finished and the garbage collection vehicle is moved to a garbage processing site, etc. After that, the input box 3 is raised to a predetermined angle, and the ejection plate 5 is placed at the front position inside the storage box 1.
is slid rearward by the extension operation of the discharge cylinder 6, and the dust inside the storage box 1 is discharged from the rear end opening of the storage box 1.

Problems that the invention aims to solve By the way, most of the garbage handled by the above-mentioned compaction type garbage collection vehicle is bulky, and this includes the boards of furniture and the like that are no longer needed. When garbage including this type of plate material is put into the input box 3, the upper and lower actuating plates 8 as shown in FIGS. 3 and 4
After the predetermined operation of the upper and lower actuating plates 8a and 8b, the upper and lower actuating plates 8a and 8b rise as shown in FIG. is displaced while drawing a gentle arc, so when the upper actuating plate 8a rises, the gap between the upper actuating plate 8a and the shielding plate 11 changes, and if the gap becomes larger, the plate material A in the garbage will move upward. It is scraped up as the actuating plate 8a rises,
In some cases, it adhered to the plate surface 13 of the shielding plate 11 on the input box side (see Fig. 2). This shielding plate 11
If the plate material A adheres to the plate material A, the upper operating plate 8a may come into contact with the plate material A during the subsequent loading operation, making it impossible to carry out a smooth loading operation, and it is also difficult for the worker to remove the plate material A. It was hot. Therefore, it has been desired to prevent the plate material A from adhering to the shielding plate 11 as much as possible and to promptly remove the plate material A.

Means for solving the problem: A shielding plate installed in the upper half of the garbage collection vehicle between the garbage storage box and the garbage input box, an upper operating plate and an upper actuator housed inside the garbage input box. A lower actuating plate is rotatably attached to the lower end of the plate, and the upper actuating plate is configured to draw an arcuate trajectory extending in the vertical direction within the garbage disposal box without coming into contact with the shielding plate. In the case where the garbage in the garbage storage box is loaded into the garbage storage box from below the shielding plate after being oscillated and the lower operating plate is rotated in conjunction with this oscillation to compress the garbage in the garbage storage box, A protruding member is formed over the entire width of the intermediate position of the plate surface of the shielding plate on the side of the garbage input box to prevent plate-shaped garbage from adhering to the plate surface of the shielding plate due to the upward movement of the upper operating plate, Further, the tip of the protruding member is located at a position where it does not come into contact with the upper operating plate when the upper operating plate swings.

Function As described above, by forming the protruding member over the entire width of the intermediate position of the plate surface on the garbage disposal box side of the shielding plate, the plate material scraped up by the upward movement of the upper operating plate is This prevents the shielding plate from being scraped up along the plate surface to the top of the shielding plate.

Embodiment An embodiment of the present invention is shown in FIGS. 6 to 9 and will be described. In the drawings, the same reference numerals as in FIGS. 2 to 5 indicate the same components, and the explanation will be omitted. The difference from the conventional device of the present invention is that a protruding member 14 is provided on the plate surface 13 of the shielding plate 11 on the side of the input box over the entire width of the shielding plate 11 at approximately the middle position in the height direction, and The tip of the protruding member 14 is located at a position where it does not come into contact with the upper actuating plate 8a when the upper actuating plate 8a swings, and the other configurations are the same as the conventional device.

In the above configuration, the protruding member 14 according to the present invention
During the garbage loading operation using a compression type garbage collection vehicle equipped with a compression type garbage collection vehicle, the upper and lower operating plates 8a and 8b in the input box 3 are in the state shown in FIG. 6, that is, the first telescopic cylinder 10a is contracted to the minimum. When the second telescoping cylinder 10b is activated and the second telescoping cylinder 10b is extended to a predetermined length to be arranged in a substantially straight line and the garbage 12 is compressed, the first telescoping cylinder 10a is then extended as in the conventional case. When activated, the upper and lower actuating plates 8a, 8b rise diagonally forward and move to the basic position shown in FIG. 7, and the compressed garbage 12 is loaded into the storage box 1. At this time, even if the plate material A, such as a plastic plate, contained in the garbage 12 is scraped up as the upper actuating plate 8a rises and enters the gap between the upper actuating plate 8a and the shielding plate 11, the plate material A will protrude. The shielding plate 1 is locked along the plate surface 13 of the shielding plate 11 by the shaped member 14.
Since the plate material A is prevented from being scraped up to the upper part of the shielding plate 11, the plate material A does not completely adhere to the plate surface 13 of the shielding plate 11. After that, the next garbage 12' is thrown into the input box 3, and in order to compress and load this garbage 12', from the state shown in FIG. 7, the lower actuating plate 8b is turned counterclockwise as shown in FIG. After rotating the upper and lower actuating plates 8 in the direction shown in FIG.
When a and 8b are lowered, the gap between the shielding plate 11 and the upper actuating plate 8a increases due to this movement.

At this time, since the plate material A is not completely attached to the plate surface 13 of the shielding plate 11, the plate material A is not completely attached to the plate surface 13 of the shielding plate 11.
It naturally falls from the plate surface 13 due to its own weight, and is then loaded into the storage box 1 together with the garbage 12'. Therefore, the plate material A will not become a problem in the subsequent garbage loading work.

In addition, although the above embodiment shows an example in which the protruding member 14 has an L-shaped cross-section, the cross-sectional shape of the protruding member 14 is not limited to this, and the upper actuating plate Of course, the shape may be other than the L-shape as long as the shape protrudes from the plate surface 13 of the shielding plate 11 to the extent that it can hold the plate material A that is raised as the plate 8a rises.

Effects of the Invention In this invention, the upper actuating plate performs an arcuate swinging motion, which changes the interval between the gaps formed between the shielding plate and the upper actuating plate. Even if the board material scraped up by the above-mentioned gap comes into contact with the plate surface of the shielding plate, the board material is prevented from being scraped up along the board surface of the shielding plate to the top of the shielding plate. By focusing on the fact that when the upper actuating plate begins its downward movement and the gap between the shielding plate and the upper actuating plate expands, the plate will naturally fall from the surface of the shielding plate due to its own weight. A protruding member is formed over the entire width of the intermediate position of the surface of the shielding plate to prevent it from being raised to the upper part of the surface of the shielding plate. Therefore, even if the plate material contained in the dust enters through the gap between the upper actuating plate and the shielding plate, the plate material will not remain attached to the plate surface of the shielding plate, but will naturally fall under its own weight, so that the upper and Loading work can be carried out smoothly using the lower actuating plate, and there is no need for an operator to remove the plate material attached to the shielding plate as in the past, which saves time and effort.
