Abstract

PROBLEM TO BE SOLVED: To attract metallic materials in wastes, by fixing a magnet at the bottom to apply or disconnect the magnetic force at the cab and forming fixed breaking disks at the bottom plate of the body and pivotting movable breaking teeth at the body and providing shearing cutters in the breaking disk and the breaking tooth. SOLUTION: Fixed breaking disks 11 are formed at both right and left side faces of the scoop board 10 of a bucket and movable breaking teeth 13 are pivotted to shafts 12 so as to be set opposite to the fixed breaking disks 11. The movable breaking teeth 13 are connected to hydraulic cylinders 14 to break concrete blocks or the like and transfer waste materials by holding them between the fixed and movable breaking disks and teeth. And shearing cutters 15, 16 for reinforcements are arranged near the pivot shafts of the fixed breaking disks and the movable breaking teeth to cut off long reinforcements or the like. In this way, not only concrete waste materials can be scooped but also metallic wastes like reinforcement chips can be attracted, and hence, the capacity of the bucket can be increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a novel idea for a bucket used in an excavator of a civil engineering machine.

[0002]

The object of the present invention is to perform the function as a bucket of this kind, and at the same time scoop up concrete waste materials scattered at the site of demolition of buildings, etc., and at the same time, rebar scraps and other metal materials contained in the waste materials. It is to obtain a product having the ability to adsorb.

[0003]

Means for Solving the Problems According to the means of the present invention, a magnet is fixedly mounted on the bottom of a bucket, means for sending and receiving the magnetic force is provided in the driver's seat, and the bottom plate of the bucket body is a fixed crusher. The movable crushing tooth plate facing this is pivotally attached to the bucket body, and a shearing cutter is provided in the fixed crushing disc and the movable crushing tooth disc in the vicinity of the pivoting portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 in FIGS. 1 and 2 denotes a working arm of an excavator 2 to which a bucket 3 is attached at its tip. The bucket body 3 has an electromagnet or a permanent magnet 4 fixed to the bottom surface or side surface of the bottom. In the case of the electromagnet 4, equipment that can be operated from the driver's seat 5 is provided. Reference numeral 20 in FIG. 5 is an operation handle. The permanent magnet 4 is also provided with means for removing the rebar scraps or the like adsorbed to the permanent magnet 4 to a predetermined position, and then leaving the magnetism absorption region. It is conceivable to make the magnetic absorber holding the permanent magnet rotatable or to eliminate the other magnetic force. Next, in the example shown in FIG. 3, in addition to equipping the bucket 3 with the permanent magnets 4, fixed crushers 11 are formed on both left and right sides of the scooping board 10 of the bucket 3, and the shaft 1 is opposed to the fixed crusher 11.
The movable crushing toothed disk 13 having the fulcrum 2 as a fulcrum is pivotally connected to the movable crushing toothed disk 13 by connecting it to the hydraulic cylinder 14 to crush concrete C and the like, and as shown in FIG. The movable crushing dental disc 13 can be grasped and carried. Fixed crusher 11 and movable crusher 13
Shear cutter 1 of rebar S on one side in the vicinity of the axis of
5 and 16 are provided, and things such as long rebars can be cut off by the shear cutters 15 and 16.

[0005]

According to the present invention, the performance of the excavator as a bucket is improved because the concrete waste material and the like can be scooped by the bucket and the metal waste material such as the reinforcing bar scrap can be adsorbed and treated. Further, if necessary, the concrete or the like is crushed, grasped, and the rebar scraps grasped together can be cut off by a shearing cutter, which further increases the actual profit.
