Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo handling bucket which can easily discharge highly viscous cargo such as clay and water-containing powder.

[0002]

2. Description of the Related Art Buckets are used to pick up, transport, and discharge cargo materials such as earth and sand and powder in cargo vehicles such as shovel loaders, tractor shovels, and forklifts. For example, as shown in FIG. 5, in the shovel loader 9, the bucket 91 is rotatably supported by a bucket bracket 93 having a triangular plate shape. A rod 96 and a lift arm 97 are connected to the bucket bracket 93. Further, the bucket 91 has a dump cylinder 95 for scooping and discharging operations.
Are connected via a piston rod 951. By the way, in the conventional cargo handling bucket, as shown in FIG. 5, when the cargo handling article 8 is discharged, the cargo handling article 8 may adhere and remain on the bottom of the bucket 91. In particular, when handling a highly viscous cargo-handling material 8 such as clay or a tofu residue (okara) containing water, a large amount is often attached. Therefore, conventionally, when the above-mentioned adhesion occurs, the piston rod 951 of the dump cylinder is caused to make a piston motion, and the stopper 911 on the bucket 91 side and the stopper 931 on the bucket bracket 93 side violently collide. Then, due to this collision, a dump shock was given to the bucket 91 to discharge the attached cargo work.

[0003]

[Problems to be Solved] However, even if the dump shock is given, the cargo handling material 8 having a high viscosity remains in the bucket 9
There is a problem that the work efficiency is lowered because the dump shock is repeatedly performed without dropping from 1 easily, and in some cases, the worker needs to get off and scrape the cargo. Further, due to repeated dump shocks, a large amount of shock and vibration are applied to each part of the machine base such as the bucket 91, the bucket bracket 93, etc., which may cause discomfort to the operator and shorten the life of each part of the machine base. . Furthermore, when a dump shock is performed, a tapping sound is generated, which may reduce discomfort to the worker or a person near the workplace. In view of such conventional problems, the present invention intends to provide a cargo handling bucket which can easily discharge cargo handling goods in the bucket, which has good working efficiency and excellent durability .

[0004]

According to the present invention, in a bucket attached to a work arm of a cargo handling vehicle, a flexible discharge plate made of a flexible plate is arranged on an inner surface of the bucket, and the flexible discharge plate is disposed. The tip of the plate is fixed to the inner surface of the bucket, while the rear end of the flexible discharge plate is connected with a wire for pulling the flexible discharge plate.

When the wire is connected to the cylinder device, the piston rod of the cylinder device is actuated to pull the flexible discharge plate and discharge the adhered cargo (see Embodiment 1). Such cylinder devices include hydraulic type, pneumatic type, and electromagnetic type. In particular, when a hydraulic cylinder device is used, a hydraulic system used for operating a bucket of a cargo handling vehicle can be used, which is convenient. Also,
When connecting the wire to the above bucket bracket,
During the operation of discharging the cargo in the bucket, the bucket bracket pulls the wire (see Example 2). Therefore, the rear end portion of the flexible discharge plate is pulled, and the cargo material attached to the flexible discharge plate is peeled off and discharged.

[0007]

[Operation and effect] In the cargo handling bucket of the present invention,
When scooping the cargo, the cargo enters inside the bucket opening. Therefore, the flexible discharge plate is pushed rearward by the cargo and contacts the inner wall surface of the bottom of the bucket. When the cargo is discharged to the destination, the bucket opening is directed downward. Therefore, many cargoes in the bucket are dropped and discharged. However, cargo materials with high viscosity such as clay adhere to the surface of the flexible discharge plate in the bucket and are not discharged. Therefore, the wire is pulled by the cylinder device or the like. As a result, the flexible discharge plate is pulled forward to swing and deform, and the cargo material attached to the surface of the flexible discharge plate is separated, dropped, and discharged. Therefore, the work efficiency of transporting cargo is improved. Further, since it is easy to discharge the adhered cargo, it is not necessary to perform a dump shock which hits both the stoppers of the bucket and the bucket bracket as in the conventional case. Therefore, neither damage nor noise is generated. Ma

[0008]

Embodiment 1 A cargo handling bucket according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The cargo handling bucket in this example is
It is attached to a shovel loader, and the flexible discharge plate 1 is arranged on the inner side surface 30 of the bucket 3, and the tip 10 of the flexible discharge plate 1 is fixed to the inner side surface 30 of the bucket 3.
On the other hand, at the rear end portion 19 of the flexible discharge plate, the flexible discharge plate 1
Connect the wire 13 for pulling. The cylinder device 2 is connected to the rear end 131 of the wire 13. Further, the bucket bracket 93 and the like attached to the rear portion of the bucket 3 are the same as those in the above-mentioned conventional technique.

The flexible discharge plate 1 is, as shown in FIG.
It is a flexible rubber sheet and has a mounting hole 11 at its tip 10 for fixing to the inner surface 30 of the bucket 3. Further, the flexible discharge plate 1 has a mounting hole 12 for mounting the wire 13 at the rear end portion 19. The mounting hole 1
A wire 13 is connected to 2 via a connection fitting 15. On the other hand, in the bucket 3, as shown in FIG. 3, a fixing plate 32 having an L-shaped cross section is welded to the lower portion of the inner side surface 30 thereof. Further, guide rolls 35 and 36 for guiding the wire 13 are provided above and on the upper end of the inner surface of the bucket 3. The guide rolls 35, 36
Is rotatably supported by roll brackets 351 and 361.

When the flexible discharge plate 1 is attached to the bucket 3, as shown in FIG.
The tip portion 10 of the flexible discharge plate 1 is positioned between the fixing plate 32 and the inner surface of the bucket, and both are fixed by bolts 33. As a result, the tip portion 10 of the flexible discharge plate 1 is fixed to the bucket 3 and covered by the fixing plate 32. The cylinder device 2 is fixed to the upper outer surface of the bucket 3 as shown in FIG. The tip end 131 of the wire 13 is connected to the tip of the piston rod 21. Further, the cylinder device 2 utilizes a part of a hydraulic operating system used for operating the shovel loader, and its operating lever is provided in the driver's seat.

Next, the function and effect will be described. In the cargo handling bucket of this example, when the cargo is scooped, the cargo 8 enters inside the opening of the bucket 3. Therefore, the flexible discharge plate 1 is pushed backward by the load 8 and comes into contact with the inner wall surface of the bottom of the bucket 3. At this time, the piston rod 21 of the cylinder device 2 is in the extended state and the wire 13 is in the loose state. Then, when carrying the picked-up cargo 8 and then discharging it, the opening of the bucket 3 is directed downward as in the conventional case. As a result, most of the cargo 8 is discharged.

At this time, when a part of the cargo 8 remains in the bucket 3 as shown in FIG. 1, the cylinder device 2 is operated and the piston rod 21 is contracted. As a result, the wire 13 becomes the guide roll 3
It is guided by 5,36 and pulled. Therefore, as shown by the dotted line in the figure, the flexible discharge plate 1 is also pulled forward,
It deforms as it rocks. Therefore, the remaining cargo material 8 is separated from the flexible discharge plate 1 and easily dropped and discharged. Further, in this example, the tip portion 10 of the flexible discharge plate 1 is
Is covered with the L-shaped fixing plate 32, the tip portion 10 is not damaged when the cargo is scooped up. Further, the wire 13 is the guide rolls 35, 36 described above.
Since it is suspended on the inside of the bucket 3,
The wire 13 does not hang down. Therefore,
That the wire is damaged when the yard 13 comes into contact with the cargo 8
I don't care. After discharging the entire amount, the piston rod of the cylinder device 2 is extended. Then move on to the next scooping operation. The pulling operation of the wire 13 can be performed every time whether the cargo 8 is attached or not, or can be performed every several discharging operations, or can be performed several times after one discharging operation. . Further, according to this example, it is not necessary to perform the dump shock as in the conventional technique. Therefore, the bucket, bucket bracket, etc. are not damaged and no noise is generated.

Embodiment 2 In this embodiment, as shown in FIG. 4, the rear end portion 13 of the wire 13 is
In this example, 1 is fixed to the bucket bracket 93. Others are the same as in the first embodiment. In this example, as indicated by the solid line in the figure, the flexible discharge plate 1 is in contact with the bottom inner surface of the bucket 3 when the bucket 3 is picking up the cargo 8. At this time, the wire 13 is in a slightly loosened state. On the other hand, when the cargo 8 is discharged, the bucket 3 rotates about the connecting pin 935 of the bucket bracket 93 and the bucket 3 as a fulcrum, as shown by the dotted line in FIG. By this rotation, as is known from the figure, the distance between the rear end portion 131 of the wire 13 fixed to the bucket bracket 93 and the roller 36 for guiding the wire 13 becomes long. Therefore, at the time of discharging, the wire 13 and the flexible discharging plate 1 are automatically pulled in the direction of the bucket bracket 93 as shown by the dotted line in FIG. Then, the cargo material attached to the flexible discharge plate 1 is separated and discharged as in the first embodiment. Therefore, according to this example, the flexible discharge plate 1 can be automatically pulled every time the cargo is discharged. Moreover, the same effect as that of the first embodiment can be obtained.
