Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to an attachment used for a bucket of a power shovel used for civil engineering work.

[0002]

2. Description of the Related Art A power shovel is a civil engineering machine whose main purpose is excavation work. However, there are cases in which ground leveling work is performed after the excavation work. In this case, the excavation claw at the tip of the excavation bucket has a bucket width and A method is used in which rectangular iron plates each having a claw length on one side are welded, and grounding work is performed on the end faces of the iron plates.

[0003]

However, when the excavation work is finished and the ground leveling work is to be performed, the method of welding the iron plate to the bucket is such that the on-site welding is troublesome, and the excavation work is performed again. The work of removing the welded iron plate is difficult.

An object of the present invention is to provide a bucket attachment for a power shovel that can perform both excavation work and ground leveling work without such trouble or difficulty.

[0005]

This invention for achieving the above object is described as follows. An iron sheath 5 for covering a claw 2 of a bucket 1 and one end of the sheath 5 are provided at the other end of the bucket 1. It is an attachment for a bucket of a power shovel, which comprises an arm 6 having a fixing portion 6a fixed to the drainage hole 7. Further, the bucket attachment of the power shovel comprises the sheath body 5 and a long arm 9 having one end provided on the sheath body 5 and the other end attached to the rear portion of the bucket 1 provided with a mounting portion 10. Also, the sheath body 5 has an outer side 5
The attachment for a bucket of the power shovel has a leveling member 18 orthogonal to the sheath body 5 at a.

[0006]

In the case of excavating a groove or the like with a power shovel and subsequently leveling the remaining soil, the iron sheath 5 is mounted and fixed to the bucket 1 with a claw used for excavating the groove. Power shovel, from the driver's seat, bucket 1
Since it is possible to make a horizontal reciprocating motion back and forth, it is possible to level the ground by horizontally reciprocating the end face of the sheath body 5 while applying the end face of the sheath body 5 to the ground. When the leveling is completed, the sheath body 5 can be removed and the bucket 1 can be returned to the excavation work again.

Next, when using the leveling member 18,
The leveling member 18 fixed to the sheath body 5 is applied to the ground in a posture of standing vertically on the ground, and the power shovel is moved forward or backward from the driver's seat of the power shovel while swinging the bucket 1 left and right. It becomes possible to level the ground leaving the locus.

1 is a perspective view showing a first embodiment of the present invention. Reference numeral 1 is a bucket, 2 is an excavating claw fixed to the bucket 1, 3 is a side cutter, and 4a and 4b are arm portions for operating the bucket. 5 is an iron sheath that forms the main part of the detachable grounding work attachment of this invention.
A flexible strip-shaped arm 6 attached to cover the claw 2 and fixed to the base end of the iron sheath 5 is formed in the bottom plate 1a of the bucket 1 to drain water. 7, the fixing portion 6a having a hole is fixed to the drain hole 7 with a bolt nut 8. Therefore, the sheath body 5 is firmly attached and fixed to the claw 2 and forms a part of the bucket. FIG. 2 shows another method of fixing the sheath body 5 to the bucket 1. An arm 6 made of a wire is used as an example instead of the strip plate, and a fixing portion 6a having a thimble is provided at the tip of the arm 6, and the thimble is fixed. It is fixed to the drain hole 7 with a bolt nut 8. In addition, FIG. 3 shows, as an example, a mounting portion 10 such as a hook is provided at the tip of the long arm 9 using a wire, hooked on the end of the bottom plate 1a of the bucket 1, and tightened by a turnbuckle 12, and the sheath 5 is attached to the bucket 1. It is firmly attached.

How the grounding work is performed by the sheath body 5 thus attached to the bucket 1 will be described with reference to FIG. By operating the arm portions 4a, 4b and the arm rod 4c, the sheath body 5 is reciprocated in the direction of arrow A5 while holding the tip of the sheath body 5 in a position in contact with the ground. , Cut the embankment 17 and level it.

In another embodiment, as shown in FIG. 5, a leveling member 18 is fixed to the center of the outer side 5a of the sheath body 5 so as to be orthogonal to the outer side 5a, and the outer surface of the bucket 1 looks like a dorsal fin. A shape-equalizing member 18 is provided. Further, FIG. 6 shows a narrow iron sheath 5s corresponding to one of the claws 2,
The leveling member 18 is fixed. A method for leveling work according to this embodiment will be described with reference to FIG.
When the sheath body 5 is held at a position where the distal end of the sheath body 5 is in contact with the ground by operating the a, 4b, and the arm rod 4c, the sheath body 5 points to the ground 16.
Stands upright against. In this state, the bucket 1 is shaken to the left and right by the operation of the driver's seat, so that the embankment 17 is broken down to level the ground. Further, by moving the power shovel forward or backward while swinging the bucket 1 to the left or right, it is possible to perform leveling that leaves a fan-shaped trajectory.

[0011]

As described in the present embodiment, the detachable attachment for ground leveling work is prepared to weld the iron plate to the claw for power shovel work in which excavation work and ground leveling work occur alternately. It is possible to omit the troublesome welding of an iron plate on site and the difficult work of removing the iron plate in the conventional method.

The ground leveling attachment of the present invention can be attached to and detached from the conventional bucket for excavation work with almost no processing modification, and thus has a high utility value.

Further, when performing a leveling work using an attachment for leveling work in which a leveling member is fixed to the sheath body,
Even if the bucket is moved back and forth or shaken to the left and right, the ground leveling function is provided, so that the ground leveling work can be effectively performed.
