However, in the bucket device for construction machinery described in Patent Documents 1 and 2, since the capacity of the bucket body is reduced by installing the electromagnet, the bucket body can be thrown into the crusher or loaded into the dump truck in one operation. There was a problem that the amount of rubble was reduced and the work efficiency was poor.

The present invention has been made by paying attention to such a problem, and an object of the present invention is to provide a bucket device for construction machinery, which is capable of sorting iron materials by an electromagnet and has good work efficiency by a bucket body. ..

In order to achieve the above object, the bucket device for construction machinery according to the present invention has an electromagnet between the inside of the bucket body having an opening and a bottom and the bottom, and the electromagnet is placed on the outer surface of the bottom. The bucket body is characterized by having a suction portion and having an increased capacity corresponding to the installation space of the electromagnet.
In the bucket device for construction machinery according to the present invention, the bucket main body is made after removing the reinforcing bars and the like contained in the concrete rubble generated from the building demolition site, etc. by the suction part of the electromagnet on the outer surface of the bottom of the bucket main body. Concrete rubble can be put into a crusher or loaded into a dump truck. Since the capacity of the bucket body is increased by the installation space of the electromagnet, the work efficiency is good without reducing the capacity that can be accommodated.

In the bucket device for construction machinery according to the present invention, it is preferable that the operation switch of the electromagnet is provided in the cab for driving the bucket body.
In this case, since the electromagnet can be operated by the operation switch in the driver's cab, the work of sorting the iron material by the electromagnet is easy.
In the bucket device for construction machinery according to the present invention, it is preferable that the power source of the electromagnet is shared with the power source for driving the bucket body.
In this case, since it is not necessary to provide the power supply for the electromagnet separately from the power supply for the bucket body, the cost of the power supply can be reduced and the overall size can be reduced.

According to the present invention, it is possible to provide a bucket device for construction machinery, which is capable of sorting iron materials by an electromagnet and has good work efficiency by a bucket body.

It is a perspective view which shows the bucket device for construction machinery of the Embodiment of this invention. It is a partial notch side view of the bucket device for construction machinery shown in FIG. 1. It is a rear view of the bucket device for construction machinery shown in FIG. 1.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a bucket device for construction machinery according to an embodiment of the present invention.
The bucket device 1 for construction machinery has a bucket main body 10 and an electromagnet 20. The bucket body 10 has a divergent U-shaped cross section, side plates 11 are parallel to each other, and have a rectangular opening 12. The bucket body 10 has a bottom portion 13 on the front side adjacent to the opening 12. Further, the bucket main body 10 has a claw portion 14 projecting to the front side of the opening portion 12.

The bucket body 10 has two pairs of upper and lower bearings 15 and 16 at the rear portion. The pair of bearings 15 on the upper side are arranged at a position higher than the opening 12. The lower pair of bearings 16 is located lower than the upper pair of bearings 15. The tip of an arm 2 of a construction machine such as a hydraulic excavator is rotatably attached to a pair of bearings 15 on the upper side. One end of a link 4 connected to a hydraulic cylinder 3 is rotatably attached to a pair of bearings 16 on the lower side. The angle of the opening 12 of the bucket body 10 can be changed by moving the lower pair of bearings 16 with respect to the upper pair of bearings 15.

The electromagnet 20 is in contact with the bottom 13 and is arranged between the inside of the bucket body 10 and the bottom 13. The electromagnet 20 is covered with a cover material 17 inside the bucket body 10. The suction portion 21 of the electromagnet 20 has a plate shape and is attached to the outer surface of the bottom portion 13. Since the suction portion 21 is not covered with a cover or the like, the reinforcing bar or the like can be strongly sucked. The power source of the electromagnet 20 is shared with the power source for driving the bucket body 10. The operation switch of the electromagnet 20 is provided in the driver's cab that drives the bucket body 10. The operation switch consists of a push button type switch that is easy to operate.

The capacity of the bucket body 10 is increased by the installation space of the electromagnet 20. The capacity can be increased by attaching a frame material matching the size of the opening 12 to the opening 12. The material and thickness of the frame material are set in consideration of strength. Instead of attaching the frame material to the existing bucket main body 10, a bucket main body designed and manufactured in consideration of capacity, strength, depth, width and the like may be used.

Next, the action will be described.
For example, when disposing of concrete rubble generated from a building demolition site, the bucket device 1 for construction machinery removes the reinforcing bars and the like contained in the concrete rubble, and then throws the concrete rubble into a crusher or dumps it. Suitable for loading on trucks. First, the push button type operation switch provided in the driver's cab is operated to turn on the electromagnet 20.

The bucket body 10 is operated, and the bottom 13 of the bucket body 10 is placed on the concrete rubble. The suction portion 21 of the electromagnet 20 attached to the outer surface of the bottom portion 13 attracts the reinforcing bars and the like contained in the concrete rubble, and moves the bucket body 10 to a predetermined accumulation place while being attracted. If the electromagnet 20 is turned off by operating the operation switch, the reinforcing bars and the like can be separated from the suction portion 21 and collected at the accumulation place. By repeating the work, iron materials such as reinforcing bars can be removed from the concrete rubble.

Next, the bucket main body 10 can be driven with the electromagnet 20 turned off, and the bucket main body 10 can throw concrete rubble or the like into a crusher or load it into a dump truck. Since the bucket main body 10 has an increased capacity corresponding to the installation space of the electromagnet 20, the work efficiency is good without reducing the capacity that can be accommodated.
Since the power supply of the electromagnet 20 is shared with the power supply for driving the bucket main body 10 and it is not necessary to provide the power supply of the electromagnet 20 separately from the power supply of the bucket main body 10, the cost of the power supply can be reduced and the whole can be reduced. Can be miniaturized.
