Bucket assembly for excavator

Abstract

Provided is a bucket assembly having a grappling member for excavator. The bucket assembly includes: a forward and backward tilting unit for forwardly and backwardly tiling a supporting plate mounted at a boom of the excavator through a first hinge bracket; a rotating unit rotatably disposed under the supporting plate of the forward and backward tilting unit; a driving unit including a supporting frame disposed under the rotating unit, a bucket member and a grappling member mounted to face the bucket member for driving the bucket member and the grappling member using an oil pressure, wherein the supporting frame and the grappling member have a bucket tooth with a hard metal tip and a grappling tooth with a hard metal tip; and a left and right tilting unit mounted at both of the forward and backward tilting unit and the rotating unit to tilt the rotating unit using oil pressure.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a bucket assembly having a grappling member for an excavator; and more particularly, to a bucket assembly having a grappling member for conveniently and efficiently laying stones and armored stones, loading and unloading woods, burying concrete pipes, and saving people from disasters by allowing an excavator to rotate a bucket member and a grappling member within 360° as well as tilting them in a left direction and a right direction in order to change a posture of a holding object and to move the holding object without damaging. DISCUSSION OF PRIOR ART [0002] In order to expand functions and applicable fields of an excavator, a grapple was additionally equipped with a bucket or independently assembled without the bucket at the excavator. [0003] Such a conventional grapple for the excavator was introduced in Korea Patent Publication No. 2001-003054, entitled “EXCAVATOR HAVING GRAPPLE,” and FIG. 1 shows the excavator havin...

AI Technical Summary

Benefits of technology

[0018] A bucket assembly having a grappling member for an excavator, which includes a forward and backward tilting unit, a rotating unit, a driving unit and a left and right tilting unit, according to the present invention provides following advantageous effects.

[0019] At first, the bucket assembly having the grappling member according to the present invention requires less man power to lay stones for landscape or armor stones for building a breakwater, to load or unload woods, to bury a concrete pipe and to save people from disasters. Therefore, cost thereof can be reduced.

[0020] Secondly, the bucket assembly having the grappling member according to the present invention requires less number of workers for manual processors at a construction field. Therefore, the number of processes for the target construction is reduced and the period of construction is shortened, accordingly.

[0021] Furthermore, the bucket assembly having the grappling member according to the present invention enables the excavator to tile a holding object using a tilting oil pressure cylinder.

[0022] Moreover, the bucket assembly having the grappling member according to the present invention enables the excavator to rapidly hold a target object by including both of the bucket member and the grappling member and to rotate the holding object within 360° in the clockwise and the counter clockwise. Therefore, the excavator is allowed to change the posture of the holding object and to stack the holding object without moving itself, conveniently.

[0023] Additionally, the bucket assembly having the grappling member according to the present invention enables the excavator to rapidly change the posture of the holding object. Therefore, the excavator having the bucket assembly according to the present invention can perform accurate operations such as laying stones for landscape and armor stones for a breakwater and burying the concrete pipes.

Problems solved by technology

However, the conventional excavator must move or rotate by itself to change a posture of the stone or the wood due to the lack of capability to turn and to rotate the bucket 2 and the grappling arm 6 to a right and a left direction.

Therefore, the productivity thereof is reduced and the operational range is limited due to the lack of capability to turn and to rotate.

Therefore, the holding operation may be malfunctioned due to the externally-exposed gear assembly 10.

Such a limitation makes the excavator unable to perform accurate operations.

It cannot be used for excavating because the bucket is not assembled with the grapple 8.

Therefore, various operations cannot be alternatively performed.

However, it cannot be used to lift up the stone, the woods or the pipes.

Also, it cannot be used to tilt in the left direction and the right direction.
