[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a refuse loading apparatus for a refuse collection vehicle according to the present invention will be described below with reference to FIGS. Note that the same or corresponding parts as in FIGS. 4 and 5 are denoted by the same reference numerals and described.

In FIG. 1, reference numeral 11 denotes a press plate,
A base plate 13 rotatably provided at the lower end of the packer plate 3 via a pivot 12, and a tip side plate 15 rotatably provided at a lower end of the base plate 13 via a pivot 14. And divided in the height direction. A base side rotation cylinder (not shown) is connected between a bracket 13a located on the back side of the base side plate 13 and a bracket (not shown) located on the back side of the packer plate 3, and is connected to the base side rotation cylinder. The base plate 13 is rotated about the pivot 12 as a fulcrum. A not-shown tip-side rotation cylinder is connected between a bracket 15a located on the back side of the tip-side plate 15 and a bracket 15a 'located on the back side of the packer plate 3, and the tip-side rotation cylinder is used by the tip-side rotation cylinder. 13 and the distal plate 15 are integrally rotated about the pivot 12 as a fulcrum, or the distal plate 15
Is pivoted on a pivot 14 separately from the base plate 13. The root-side rotation cylinder and the tip-side rotation cylinder automatically rotate the base-side plate 13 and the tip-side plate 15 separately or integrally by sequence control.

Next, the operation of the refuse loading apparatus of the present invention will be described with reference to FIG.
It will be explained by.

First, when the previous loading of dust is completed, the state is as shown in FIG. 3 (a). That is, the packer plate 3 is at the ascending end position and the press plate 1
1 is in the forward rotation end position. In this state, the next dust is thrown into the dust throwing box 1.

Next, the distal end side plate 15 of the press plate 11 is inverted (rotated counterclockwise in the figure) about the pivot 14 from the state shown in FIG. 3A to the state shown in FIG. 3B. . In this state, between the lower end of the packer plate 3 and the upper end 1b 'of the front of the drum plate 1b of the garbage input box 1,
The base plate 13 of the press plate 11 is located. Therefore, the opening between the lower end of the packer plate 3 and the upper front end 1b ′ of the drum plate 1b of the dust bin 1 is narrowed by the base plate 13 of the press plate 11, and the dust loaded in the dust storage box is reduced. Garbage input box 1
Backflow to the side can be prevented.

Next, the packer plate 3 is moved to the position shown in FIG.
From the state shown in FIG. 3 to the state shown in FIG.
Lower along 2 Since the press plate 11 is pivotally supported by the packer plate 3, the press plate 11 is also lowered simultaneously with the lowering of the packer plate 3. At this time, at the same time when the packer plate 3 starts descending, the base plate 13 of the press plate 11 is
From the state shown in FIG. 3B to the state shown in FIG.
2 is rotated around the fulcrum (counterclockwise in the figure), and the distal end plate 15 is moved from the state shown in FIG.
The pivot 14 is rotated forward (turned clockwise in the figure) around the pivot 14 until the state shown in FIG. Thus, at the position shown in FIG. 3 (f), the base plate 13 is completely inverted, and the tip plate 15 is arranged linearly with respect to the base plate 13. Press plate 1
1 is referred to as a fully inverted state. The position in the height direction when the press plate 11 is in the fully inverted state can be arbitrarily set with a dial by sequence control according to the type, size, amount, and the like of the dust.

Further, the packer plate 3 is shown in FIG.
From the state (1) to the state shown in FIG. 3 (g) by continuous operation. That is, FIG.
Between the state shown in FIG. 3 (f) and the state shown in FIG. 3 (g), the press plate 11 in the fully inverted state is further lowered as the packer plate 3 is lowered, so that the dust box 1 on the drum plate 1b is lowered. The dust is primarily compressed by the press plate 11.

Next, the press plate 11 is moved to the position shown in FIG.
From the state shown in FIG. 3H to the state shown in FIG. That is, while maintaining the base plate 13 and the tip plate 15 of the press plate 11 in a straight line, the pivot 12
Is rotated forward integrally with the fulcrum. Thereby, the primary compressed dust is secondarily compressed by the press plate 11.

Next, the packer plate 3 is moved to the position shown in FIG.
From the state shown in FIG. 3 to the state shown in FIG.
Raise along 2. As a result, the secondary compressed dust is loaded into the dust storage box by the press plate 11. Thus, one cycle of the loading cycle is completed, and the same operation as above is repeated thereafter.

The above operation describes the case where dust loaded in the dust storage box is prevented from flowing back to the dust input box 1 side. However, the dust loading status, the type and size of the dust are described. It is also possible to load dust that does not prevent backflow by switching the switch depending on the amount or the like. In this case, in order to prevent the backflow, the base plate 13 and the tip plate 15 of the press plate 11 are separately rotated at the time of inversion and integrally rotated at the time of normal rotation. Rotate integrally during both rotations.

[0023]

As described above, according to the present invention, the press plate is rotatably mounted on the base plate provided rotatably at the lower end of the packer plate and the lower end of the base plate. The top plate and the top plate provided in the above are divided in the height direction, and the base plate and the top plate are separately or integrally rotated by separate rotation means, so that the previous dust accumulation When moving from the state where loading is completed to the next loading of garbage, the opening between the lower end of the packer plate and the upper front of the drum plate of the garbage loading box can be narrowed by the base plate of the press plate Therefore, it is possible to prevent the refuse loaded in the refuse storage box from flowing back to the refuse input box side, and it is expected that the loading efficiency is improved.
