In addition, the blades shown in Modifications 6 to 9 are not limited to those provided to extend in the front-rear direction of the vehicle body, but may be provided to extend in the left-right direction of the vehicle body or in directions crossing each other.

Next, a second embodiment of the present invention will be described with reference to FIGS.

In this embodiment, not only plastic containers but also a wide range of containers including empty cans can be collected. The configuration of the pressing plate is changed so that the pressing operation of the container by the pressing plate can be performed. Thus, the pre-compression operation of the container is performed.

That is, in this embodiment, as shown in FIG. 14 to FIG. 22, the back surface 61a of the pushing plate 61 of the loading device 13 has a container G such as a plastic or empty can.
A pre-compression plate 62 for pre-compressing the compressed air with the back surface 61a of the pushing plate 61 and discharging the residual air in the container G in advance is provided so as to be able to approach and separate from the back surface 61a of the pushing plate 61.
The precompression plate 62 is supported between the left and right support pieces 22 so as to be swingable in the vehicle longitudinal direction. As shown in FIG. 23, brackets 63 (only one is shown in the figure) protruding toward the support piece 22 at a position inside the vehicle body than the respective support pieces 22 of the pushing plate 61 at both left and right ends of the pre-compression plate 62. ) Is provided. In addition, the pushing plate 6
A cylinder tube 64a of a rotary cylinder 64 extending in the left-right direction of the vehicle body is fixedly mounted on the upper surface of 1. The rotary cylinder 64 is conventionally known, and is configured to rotate a cylinder rod 64b projecting from an end face of the cylinder tube 64a forward and backward around an axis of the cylinder tube 64a. The above cylinder rod 64
b, a bracket 63 of the pre-compression plate 62 is rotatably connected to the cylinder 63, and the operation of the rotary cylinder 64, that is, the cylinder rod 64 with respect to the cylinder tube 64a.
The pre-compression plate 62 swings in the vehicle front-rear direction by the forward / reverse rotation about the axis b. In particular,
The pre-compression plate 62 is in an open position in which the pre-compression plate 62 is separated rearward from the back surface 61a of the pushing plate 61 (for example, the state shown in FIG. 15)
And a closed posture (for example, a state shown in FIG. 14) approaching the rear surface 61 a of the pushing plate 61. In this case, the axial center of the rotary cylinder 64 and the connection point on the support piece 22 side of the pushing cylinder 23 match each other in FIG. 23, but the pre-compression plate 62 swings in the vehicle longitudinal direction. It is not always necessary to match them if possible.

When the pressing plate 61 performs the compression step, the squeezing step and the pressing step, the pre-compression plate 62 is close to the back surface 61a of the pressing plate 61 to maintain the closed position. I have. On the other hand, after the pressing operation of the pressing plate 61 is completed, that is, when the pressing plate 61 is positioned at the front swinging position and stopped, the pre-compression plate 62 is rotated on the back surface 61 a of the pressing plate 61 by the reverse rotation of the rotary cylinder 64. When the container G on the bottom plate 6a is pre-compressed by descending from the open posture while holding the open posture separated from the rear, the rotary cylinder 64 approaches the rear surface 61a of the pushing plate 61 by the forward rotation of the rotary cylinder 64. After the pre-compression, the container G pre-compressed by the reverse rotation of the rotary cylinder 64 is removed from the bottom plate 6a.
The push-in plate 61 is separated from the rear surface 61a of the push-in plate 61 again to keep the open position in order to prepare for the compressing operation of the push-in plate 61. Further, the pre-compression plate 6
Reference numeral 2 denotes a state in which the pushing plate 61 holds the closed position when the pushing plate 61 reverses backward after the pushing operation is completed, and when the pushing plate 61 swings backward, the rotary cylinder 63 rotates forward to rotate the pre-compression plate. 62 swings forward so as to maintain the closed position with respect to the back surface 61 a of the pushing plate 61. In this case, even if the pre-compression plate 62 oscillates forward, the pre-compression plate 62 is positioned at the rear by being offset by the backward swing of the pressing plate 61, and the back surface 61 a of the pressing plate 61 and the pre-compression surface of the pre-compression plate 62. 62a gradually approaches and the pushing plate 61 reverses to the rear swing position, the back surface 61a of the pushing plate 61 approaches the pre-compression surface 62a of the pre-compression plate 62, and the pre-compression plate 62 The closed posture is maintained.

Further, on the pre-compression surface 62a of the pre-compression plate 62, a plurality of projections 65 protruding toward the back surface 61a of the pushing plate 61 are provided over the entire area.
The remaining structure other than the pushing plate is the same as that of the first embodiment, and the same portions are denoted by the same reference numerals and detailed description thereof will be omitted.

Here, the loading procedure of the container G by the loading device 13 will be described with reference to FIGS. In this case, it is assumed that the pushing plate 61 is positioned at the upper front position (the pushing process completion position) immediately after the pushing process is performed, and the pre-compression plate 62 is held in the closed posture.

First, as shown in FIG.
Is positioned in a state in which the container G is pushed into the storage box 4 from the loading port 4a by the pushing operation, that is, in the upper front position. In this case, a plurality of containers G to be pushed in next are thrown in from the throwing port 11 and stored on the bottom plate 6a of the throwing box 6.

Next, as shown in FIG. 15, the pre-compression plate 62 is swung rearward with respect to the back surface 61a of the pushing plate 61 by rotating the rotary cylinder 64 in the reverse direction to maintain the open position. Thereafter, as shown in FIG. 16, the precompression plate 62 is lowered together with the pushing plate 61 to the lower position of the precompression plate 62 by the lowering operation of the elevating plate 15. In this case, since the pushing plate 61 descends while being positioned at the front swinging position, the backflow of the container G pushed into the storage box 4 to the loading box 6 side through the loading port 4a is prevented. .

Then, as shown in FIG. 17, the rotary cylinder 64 is rotated forward to move the pre-compression plate 62 from the open position to the rear surface 61a of the pushing plate 61 to hold it in the closed position. As a result, the container G on the bottom plate 6a is scraped by the pre-compression plate 62 and
1a, and the residual air in the container G can be discharged in advance. In this case, even if the amount of the container G put on the bottom plate 6a is small, the small amount of the container G is surely stored between the pre-compression surface 62a of the pre-compression plate 62 and the back surface 61a of the pushing plate 61.

In this case, the pre-compression plate 62 holds the open position above the insertion port 11 while the reversing operation of the pushing plate 61 is performed.

Thereafter, as shown in FIG.
With the pre-compression plate 62 held down, the pre-compression plate 62 is lowered to the lowering position together with the pushing plate 61 while the pre-compression plate 62 is held in the closed position, and the pre-compressed container G on the bottom plate 6a is compressed in the compression process of the pushing plate 61. Accordingly, the container G from which the residual air has been discharged in the pre-compression step can be reliably compressed by the compression operation of the pushing plate 61.

Next, as shown in FIG. 22, the pushing cylinder 23 is extended to move the pushing plate 61 together with the pre-compression plate 62 around the shaft support 24 from the rear swing position to the front swing position. Then, a scraping step of scraping the container G compressed in the compression step to the front side of the bottom plate 6a is performed. Thereafter, the pushing plate 61, which has been swung to the front position in the scraping step, is moved up along with the pre-compression plate 62 along the front wall of the bottom plate 6a to the ascending position by the ascending / descending operation of the elevating plate 15, and A pushing step of pushing the raked container G from the loading port 4a into the storage box 4 is performed (a state shown in FIG. 14).

In the second embodiment, the pre-compression plate 62 is moved toward and away from the back surface 61a of the pushing plate 61 by rotating the rotary cylinder 63 forward and backward.
A switch is provided to stop the forward / reverse rotation of the rotary cylinder. When the switch is turned on, the pre-compression plate is always pushed in with the pre-compression plate kept in the closed position approaching the back of the pushing plate without rotating the rotary cylinder forward / reverse. It is also possible to operate together with the plate, in which case dust other than the container, for example, other garbage such as garbage, cardboard and bulky garbage, is compressed, scraped and pushed into the storage box. It can also be stored in garbage and is also used as a dedicated collection vehicle for garbage, cardboard and oversized garbage.

However, the bracket of the precompression plate is rotatably supported on the elevating plate, and is provided between the upper surface of the charging box and the precompression plate. A telescopic cylinder may be provided so that the pre-compression plate swings in the vehicle longitudinal direction by the telescopic operation of the telescopic cylinder. In this case, when the pre-compression plate falls down on the back surface of the push plate and swings integrally with the push plate, the hydraulic switching valve is configured so that the supply and discharge of hydraulic pressure to the telescopic cylinder is in a free state. Then, it is necessary to configure the telescopic cylinder as a simple telescopic rod.

Further, in the second embodiment, the protrusion 6
5 is provided on the pre-compression surface 62a of the pre-compression plate 62,
A plurality of protrusions projecting toward the pre-compression surface side of the pre-compression plate are provided only on the back surface of the press plate over the entire area, or the protrusions are provided on both the pre-compression surface of the pre-compression plate and the back surface of the press plate. It may be.

Further, in the second embodiment, the pre-compression plate 62 is positioned at the separated position above the insertion port 11 during the reversing operation of the pressing plate 61. However, the pre-compression plate 62 is opened when the pressing plate 61 performs the reversing operation. The inlet may be closed by a pre-compression plate that holds the posture. In this case, when the loading port is opened by the reversing operation of the push plate, even if the container flowing backward from the loading port of the storage box to the loading box side tries to jump outward through the loading port, the loading port is not Since the container is closed by the pre-compression plate that holds the open position, the container can be effectively prevented from jumping out of the container by the pre-compression plate.
