Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wear-resistant digging bucket mounted on a working machine such as a hydraulic shovel, a wheel loader, a mechanical shovel, and a tractor shovel.

[0002]

2. Description of the Related Art FIGS. 4 and 5 show that abrasion-resistant steel plates 2, 3, 4, 5, and 6 are welded to a portion of a bucket body 1 where wear is likely to occur, that is, a side portion, a bottom portion, and a corner portion of the bottom portion. 1 shows an example of a conventional digging bucket.

[0003]

In such an excavating bucket, when a wear-resistant steel plate having a large thickness is used in order to further improve the wear resistance, the weight of the bucket increases and the speed of the excavation operation decreases. .

The present invention has been made in view of the above circumstances, and has as its object to provide an excavating bucket which can extremely easily improve the wear resistance without increasing the weight of the bucket.

[0005]

In order to achieve the above object, the present invention is characterized in that a plurality of holes for press-fitting excavated earth and sand are provided in a wear-resistant steel plate to be welded to a bucket body.

[0006]

With the excavation work, excavated earth and sand is pressed into each hole of the wear-resistant steel plate, and the wear of the bucket body is prevented by the wear-resistant steel plate and the sand pressed into each hole.

[0007]

1 to 3 show an embodiment of the present invention.
This will be described below. In those figures, FIGS. 4 and 5
The same members as those described above are denoted by the same reference numerals.

A plurality of holes 7 for press-fitting excavated earth and sand 8 are provided in each of the wear-resistant members 2, 3, 4, 5, and 6 at intervals. During the excavation work, excavated earth and sand 8 is pressed into each hole 7.

[0009]

According to the invention described above, the wear of the bucket can be prevented by the wear-resistant steel plates and the excavated earth and sand pressed into the respective holes, and the life can be extended. In addition, by providing holes, the wear-resistant steel plate becomes lighter, and since each hole is filled with excavated earth and sand, the wear area of the wear-resistant steel plate due to earth and sand during excavation is reduced, and the wear resistance of the wear-resistant steel plate itself is reduced. Also improve.
