Abstract

(57) [Summary] (Correction) [Purpose] For power shovels, ground leveling work is performed after excavation work. In addition, during this leveling work, an iron plate may be welded to the excavation bucket. However, this method is also troublesome in welding, and it is difficult to remove the iron plate in the next excavation. Therefore, the ground leveling work attachment is detachably attached to the excavation work bucket to improve efficiency and save labor. [Structure] An iron sheath 5 covering the claws 2 of the excavation bucket 1
Was formed, and the arm 6 or the long arm having the fixing portion for fixing to the drainage hole 7 of the bucket or the rear portion was provided on the sheath body. Further, a leveling member was provided outside the sheath body and vertically.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an attachment used for a bucket of a power shovel used for civil engineering work.

[0002]

[Prior art]

 Power shovels are civil engineering machines whose main purpose is excavation work, but there are cases where ground leveling work is performed after excavation work.In this case, the bucket width and the length of the pawl are A method is used in which rectangular iron plates each having a length of one side are welded and the end surface of the iron plate is grounded.

[0003]

[Problems to be solved by the device]

 However, when the excavation work is completed and the ground leveling work is performed, the method of welding the iron plate to the bucket is complicated in the field welding, and when the excavation work is performed again, the welded iron plate is removed. The work is difficult.

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

[0005]

[Means for Solving the Problems]

 This invention which achieves the above-mentioned object is described as follows: an iron sheath 5 covering the pawls 2 of the bucket 1 and one end of the sheath 5 fixed to the drain hole 7 of the bucket 1 at the other end. It is an attachment for a bucket of a power shovel, which comprises an arm 6 having a portion 6a. Further, the bucket attachment of the power shovel comprises the sheath body 5 and a long arm 9 provided at one end of the sheath body 5 and attached to the rear portion of the bucket 1 at the other end thereof. Further, it is a bucket attachment of a power shovel in which a fixing member 13 having a fixing portion for fixing 6a to the side cutter 3 is provided on the sheath body 5. Further, the sheath body 5 is an attachment for a bucket of the power shovel, which has a leveling member 18 orthogonal to the sheath body 5 on the outer side 5a.

[0006]

[Action]

 When excavating a groove or the like with a power shovel and subsequently leveling the remaining soil, etc., the iron-made sheath body 5 is fixedly attached to the bucket 1 with a claw used for excavating the groove. Since the power shovel can make a horizontal reciprocating motion of the bucket 1 back and forth from its driver's seat, it is possible to make a horizontal reciprocating motion of the end face of the sheath body 5 against the ground while leveling the ground. I can. 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 the leveling member 18 is used, the leveling member 18 fixed to the sheath body 5 is applied to the ground in a posture in which the leveling member 18 stands vertically on the ground, and the power shovel driver seats By moving the power shovel forward or backward while swinging 1 to the left or right, it is possible to level the ground leaving a fan-shaped trajectory.

【Example】

 FIG. 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. Reference numeral 5 is an iron sheath that forms the main part of the removable grounding work attachment of the present invention, and is attached so as to cover the claw 2 and is fixed to the proximal end of the iron sheath 5. The strip-shaped arm 6 having elasticity extends to the drain hole 7 formed in the bottom plate 1a of the bucket 1, and the fixing portion 6a having the hole is fixed to the drain hole 7 with the bolt nut 8. There is. Therefore, the sheath body 5 is firmly attached to and fixed to the claw 2 and forms a part of the bucket. FIG. 2 shows another method for 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. It is fixed to the drain hole 7 with a bolt nut 8. In addition, FIG. 3 shows an example in which a mounting portion 11 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 the turn puckle 12 tightens the sheath body 5 to the bucket 1. It is firmly attached. Another embodiment for mounting the sheath body 5 will be described with reference to FIG. 4. Since the side cutter 3 (see FIG. 1) is not necessary in the ground leveling work, the side cutter 3 is removed and its attachment is performed. The bolt holes 14 are used, and the side plates 13 are fixed to both sides of the sheath body 5 as shown in FIG. 4, and the side plates 13 are fixed by the bolt nuts 15 using the bolt holes 14 of the side cutter 3. .

How the grounding work is performed by the sheath body 5 attached to the bucket 1 in this way will be described with reference to FIG. By operating the arm portions 4a, 4b and the arm rod 4c, the sheath body 5 is made substantially vertical to the ground 16, and while the tip of the sheath body 5 is held in a position in contact with the ground, the sheath body 5 is reciprocated in the direction of arrow A5. Cut down the embankment 17 and level.

In another embodiment, as shown in FIG. 6, 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. It is provided with a leveling member 18 having a regular shape. Further, in FIG. 7, the leveling member 18 is fixed to the narrow iron sheath 5s corresponding to one of the claws 2. A method for leveling work according to the present embodiment will be described with reference to FIG. 8. The distal end of the sheath body 5 is brought into a state in which the sheath body 5 points to the ground 16 by operating the arm portions 4a, 4b and the arm rod 4c. Is held in contact with the ground, the leveling member 18 rises perpendicular to the ground 16. In this state, by operating the driver's seat, the bucket 1 is swung to the left and right to break the embankment 17 and level the ground. In addition, it is possible to level the ground leaving a fan-shaped trajectory by moving the power shovel forward and backward while swinging the bucket 1 left and right.

[Effect of device]

 By preparing a detachable attachment for ground leveling work as described in this embodiment, in the conventional method of welding an iron plate to a claw in a bower shear work in which excavation work and ground leveling work occur alternately, It is possible to omit the troublesome welding of steel plates on site and the difficult work of removing the steel plates.

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

In addition, when performing a leveling operation using an attachment for leveling work in which a leveling member is fixed to the sheath body, a leveling function is provided when the bucket is moved back and forth and when it is shaken left and right. Therefore, the ground leveling work can be performed effectively.
