Abstract

PROBLEM TO BE SOLVED: To perform excavating work and gripping work by a single unit by constituting a bucket clam of a main bucket, a sub-bucket and a sub-link on the tip of an arm through a bracket, and opening/closing the main bucket and the sub-bucket by extension/contraction of a hydraulic cylinder. SOLUTION: A bracket 19 is fixed to the tip of an arm 11 by pins 20 and 21, and a main bucket 10 is rotatably supported by a part of the bracket 19. A sub-bucket 13 is rotatably installed in a part of the bracket 19 so as to be opposed to the main bucket 10. A part of the sub-bucket 13 and a part of the main bucket 10 are connected to each other by a sub-link 14, and are interlocked with opening/closing operation of both. When the main bucket 10 is opened by a hydraulic cylinder 16, the sub-bucket 13 is also opened. When the main bucket 10 is closed, the sub-bucket 13 is also closed. The sub-link 14 can be mounted and demounted, and is fixed by a pin to a part of the arm 11 by removing an end part on the main bucket 10 side.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a bucket crumb used for excavation in civil engineering work and construction work.

[0002]

2. Description of the Related Art Generally, a power shovel or the like performing an excavation operation cannot perform a gripping operation only by scooping earth and sand with a bucket.

[0003]

Therefore, with the above-mentioned conventional power shovel or the like, even if the earth and sand can be scooped, the work of grasping an object and dismantling the building cannot be performed. For this reason, conventionally, for dismantling work of a wooden house or the like, it has been necessary to bring a fork glove separately in addition to the bucket. Conventionally, when attaching another attachment to a power shovel or the like, it has been necessary to modify or weld the tip of the arm or the like.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bucket crumb which can perform both ordinary excavation work and work for grasping an object and does not require remodeling of the tip of an arm. It is in.

[0005]

SUMMARY OF THE INVENTION A bucket crumb according to the present invention comprises a bracket fixed to the tip of an arm of a construction machine, a main bucket rotatably mounted on a part of the bracket, and one of the brackets. A sub-bucket rotatably mounted on the part, a sub-link connecting a part of the sub-bucket and a part of the main bucket, and interlocking the opening and closing operations of the two, and a hydraulic pressure disposed on a construction machine or the like. The main bucket and the sub-bucket can be opened and closed by expansion and contraction of a cylinder.

A sub-link for connecting a part of the sub-bucket and a part of the main bucket is detachable. By removing an end on the main bucket side and fixing it to a part of an arm of a construction machine or the like. The feature is that work can be performed only with the main bucket. The main bucket is rotated via a side link rotatably connected to a part of the bracket and a link rotatably connected to a part of the main bucket. It is.

As described above, the bucket crumb according to the present invention can perform both the excavating operation and the gripping operation with one unit, and is efficient.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side view showing a bucket crumb according to one embodiment of the present invention, FIG. 2 is a side view showing a main bucket used in the bucket crumb according to one embodiment of the present invention, and FIG. It is a side view which shows the sub bucket used. In the present embodiment, the main bucket 10
As shown in FIG. 2, there is provided a shaft hole 12 rotatably attached to a tip of an arm 11 of a construction machine or the like via a bracket 19, and a sub-link 14 connected to a sub-bucket 13 described later. It has a hole 15 and a pin hole 18 that is attached via a link 17 to the tip of a hydraulic cylinder 16 disposed on an arm 11 of a construction machine (not shown). The main bucket 10 has a concave portion 10a for scooping earth and sand.

As shown in FIG. 3, the sub-bucket 13 has a shaft hole 13a rotatably supported by a bracket 19, a connection hole 13b to which a sub-link 14 is connected, and an arm 11
And a fixing arm 22 for fixing the arm. The fixed arm 22 has a pin hole 22a.

A bracket 19 is fixed to the tip of the arm 11 by pins 20 and 21, and the main bucket 10 is rotatably supported by a part of the bracket 19. A sub bucket 13 is rotatably attached to a part of the bracket 19 at a position facing the main bucket 10. A part of the sub-bucket 13 and a part of the main bucket 10 are connected by a sub-link 14, and the opening and closing operations of both are linked. That is, when the main bucket 10 is opened by the hydraulic cylinder 16, the sub-bucket 13 is also opened. Conversely, when the main bucket 10 is closed, the sub-bucket 13 is also closed.

A sub-link 14 for connecting a part of the sub-bucket 13 and a part of the main bucket 10 is detachable, and a part of the arm 11 of a construction machine or the like is removed by removing an end on the main bucket 10 side. Can be fixed with a pin 23.

Next, a method of using the bucket crumb configured as described above will be described. When performing a gripping operation such as demolition of a house, the main bucket 10 and the sub-bucket 13 are connected by a sub-link 14 such that the main bucket 10 and the sub-bucket 13 are interlocked as shown in FIGS. In the case of such a configuration, it is possible to open and close by the bucket crumb of the present invention to perform a gripping operation. The house can be dismantled by the grasping operation.

When working only with the bucket 10, the main bucket 10 side of the sub-link 14 is removed and attached to the arm 11 so that the sub-bucket 13 does not interfere with the sub-bucket 13 as shown in FIG. Arm 22 with pin 23
To fix a part of the arm 11. With this configuration, even if the hydraulic cylinder 16 expands and contracts, the sub bucket 13
Remains fixed, and only the main bucket 10 rotates. Therefore, an operation suitable for excavation work can be performed.

Incidentally, the present invention is not limited to the above-described embodiment, and various design changes can be made based on the technical idea of the present invention.

[0015]

As described above in detail, according to the bucket crumb according to the present invention, a bracket fixed to the tip of an arm of a construction machine, etc., and a main bucket rotatably mounted on a part of the bracket A sub-bucket rotatably attached to a part of the bracket, a sub-link connecting the part of the sub-bucket and a part of the main bucket, and interlocking the opening and closing operations of both, The main bucket and sub-bucket can be opened and closed by the expansion and contraction of a hydraulic cylinder disposed in the arm, so that the arm of a conventional construction machine or the like can be mounted without remodeling. Both bucket and sub-bucket gripping work can be used for dismantling work.

Further, in the present invention, the sub-link for connecting a part of the sub-bucket and a part of the main bucket is detachable, and a part of an arm of a construction machine or the like is removed by removing an end on the main bucket side. Since the work can be performed only by the main bucket by fixing to the sub-bucket, the sub-bucket does not hinder the excavation work during the excavation work.
