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 civil engineering work, soil improvement work or house demolition 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. In addition, the mesh-shaped skeleton bucket can be sieved, but cannot excavate earth and sand.

[0003]

With the above-mentioned ordinary power shovel, 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,
In the demolition work of a wooden house or the like, it was necessary to bring a fork glove separately in addition to the bucket. Therefore, a bucket crumb that can perform both excavating work by a bucket and grasping work has been proposed. However, the bucket crumb, which can perform both excavating work with a bucket and grabbing work, is not suitable for work such as sorting concrete pieces and rocks and earth and sand in the remaining soil, improving soil, and sorting by rock size. Was. On the other hand, in order to sort concrete pieces and rocks in the remaining soil, a bucket having a mesh-like bottom called a skeleton bucket is used, but this skeleton bucket is not suitable for excavation of earth and sand.

SUMMARY OF THE INVENTION An object of the present invention, which has been made in view of the above-mentioned conventional disadvantages, is to provide a bucket crumb that can perform any of a concrete mass sorting operation, a normal excavation operation, and an object holding operation in remaining soil. is there.

[0005]

A bucket crumb according to the present invention comprises a bracket fixed to the tip of an arm of a construction machine or the like, and a mesh-shaped skeleton bucket rotatably attached to a part of the bracket. It is characterized in that a wear plate is detachably arranged on the skeleton bucket.

A sub-bucket is rotatably attached to a part of the bracket, a part of the sub-bucket is connected to a part of the skeleton bucket, and a sub-link for interlocking the opening and closing operations of the two is attached to a construction machine or the like. The skeleton bucket and the sub bucket can be opened and closed by expansion and contraction of a hydraulic cylinder disposed therein. Further, the wear plate is made of rubber. Further, the wear plate is a sheet material.

As described above, the bucket crumb according to the present invention is extremely easy to convert the remaining soil into waste, to excavation work, and to gripping work.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view showing a main bucket used in an embodiment of the present invention, FIG. 2 is a side view showing the main bucket, FIG. 3 is a cross-sectional view of a main part showing the main bucket, and FIG. It is a side view which shows the bucket crumb of No. In this embodiment, the main bucket 10 is connected to a shaft hole 13 rotatably attached to a tip of an arm 11 of a construction machine or the like via a bracket 12 as shown in FIG. Connection hole 1 where sub-link 15 is connected
6 and a pin hole 19 attached via a link 18 to the tip of a hydraulic cylinder 17 disposed on an arm 11 of a construction machine or the like (not shown).

The bottom of the main bucket 10 has a mesh shape, and is a so-called skeleton bucket in which earth and sand smaller than the mesh fall and rocks larger than the mesh fall.
The mesh comprises a flat bar 20 and a round bar 21 arranged at right angles to the flat bar 20. Further, a plurality of claws 22 are arranged at equal intervals at the tip of the main bucket 10.

A claw 22 is fixed to the front end of the lip plate 23, and a flat bar 20 is fixed to the rear end. On the upper surface of the lip plate 23, a guard plate 24 whose end is chamfered is fixed in the width direction. In the lip plate 23, bolt holes 25 are formed at appropriate intervals. Further, a shoulder plate 26 is attached to the back end of the main bucket 10,
Bolt holes 27 are formed at appropriate intervals. A wear plate 28 made of rubber or the like can be attached to the mesh portion of the main bucket 10 configured as described above. The wear plate 28 is fixed to the lip plate 23 with a bolt nut 29 at the front end, and is fixed to the shoulder plate 26 with a bolt nut 30 at the rear end.

As shown in FIG. 4, the sub-bucket 14 has a shaft hole rotatably supported by the bracket 12, a connection hole to which the sub-link 15 is connected, and a fixed arm for fixing to the arm 11. 31. Also, the fixed arm 31
Has a pin hole 31a.

A bracket 12 is fixed to a tip of the arm 11 by pins 32 and 33, and a main bucket 10 is rotatably supported by a part of the bracket 12. A sub bucket 14 is attached to a part of the bracket 12 so as to be rotatable at a position facing the main bucket 10. Then, a part of the sub-bucket 14 and a part of the main bucket 10 are connected by a sub-link 15, and the opening and closing operations of both are linked. That is, when the main bucket 10 is opened by the hydraulic cylinder 17, the sub bucket 14 is also opened. Conversely, when the main bucket 10 is closed, the sub bucket 14 is also closed.

A sub-link 15 for connecting a part of the sub-bucket 14 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 excavating earth and sand, the wear plate 28 is fixed to the mesh portion of the main bucket 10 with bolts and nuts 29 and 30 as shown in FIGS. In this way, even with a skeleton bucket, earth and sand can be excavated in the same manner as a normal bucket. Since the guard plate 24 is provided at the tip of the wear plate 28, it is not turned up by earth and sand.
Although the case of rubber has been described as an example of the wear plate 28, the present invention is not limited to this, and may be a sheet or an iron plate.

When sorting rocks and concrete blocks in the remaining soil, the wear plate 28 is removed from the main bucket 10 and a normal skeleton bucket is used. In this way, rocks and concrete blocks larger than the mesh can be sorted out and removed.

Further, when performing a gripping operation such as demolition of a house, the main bucket 10 and the sub-bucket 14 are connected by a sub-link 15 so as to be interlocked as shown in FIG. 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 sub-link 15 is detached from the main bucket 10 and attached to the arm 11 so that the sub-bucket 14 does not hinder the work, as shown by the broken line in FIG. Then, the fixed arm 31 is fixed to a part of the arm 11 with a pin. With this configuration, even if the hydraulic cylinder 17 expands and contracts, the sub bucket 14
Remains fixed, and only the main bucket 10 rotates. Therefore, an operation suitable for use as an excavation work or a skeleton bucket 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.

[0019]

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 or the like, and a mesh rotatably attached to a part of the bracket. Since the wear plate is detachably provided on the skeleton bucket, the work of excavation and the removal of stones and concrete blocks in the residual soil by the skeleton bucket can be performed with one bucket.

A sub-bucket is rotatably attached to a part of the bracket, a part of the sub-bucket is connected to a part of the skeleton bucket, and a sub-link for interlocking the opening and closing operations of the two is attached to a construction machine or the like. The skeleton bucket and sub-bucket can be opened and closed by the expansion and contraction of the hydraulic cylinder provided, so excavation work and removal of stones and concrete blocks from the remaining soil by the skeleton bucket,
Alternatively, the dismantling operation can be performed by a gripping operation using the main bucket and the sub bucket.

When the wear plate is made of rubber, abrasion due to earth and sand can be reduced. When the wear plate is deteriorated, it can be easily replaced.
