Abstract

(57) [Abstract] [Purpose] Easily improve the wear resistance performance of an excavating bucket in which a wear resistant steel plate is welded to the bucket body. [Structure] Wear resistant steel plates 2 and 3 to be welded to the bucket body 1
.. are provided with a plurality of excavated earth and sand press-fitting holes 7.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an excavation bucket having a wear-resistant structure which is attached to a work machine such as a hydraulic excavator, a wheel loader, a mechanical excavator, a tractor shovel or the like.

[0002]

[Prior art]

 FIG. 4 and FIG. 5 are conventional excavation buckets in which wear-resistant steel plates 2, 3, 4, 5, 6 are welded to places where the bucket body 1 is easily worn, that is, the side surface, the bottom, and the corners of the bottom. An example is shown.

[0003]

[Problems to be solved by the device]

 In such an excavating bucket, if a thick anti-wear steel plate is used to further improve the anti-wear performance, the weight of the bucket increases and the speed of excavation work decreases.

The present invention has been made in view of the above, and an object thereof is to provide an excavation bucket that can extremely easily improve the wear resistance performance without increasing the weight of the bucket.

[0005]

[Means for Solving the Problems]

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

[0006]

[Action]

 Along with the excavation work, excavated earth and sand are pressed into each hole of the wear-resistant steel plate, and the wear-resistant steel plate and the sand and sand pressed into each hole prevent wear of the bucket body.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In these figures, the same members as those in FIGS. 4 and 5 are designated by the same reference numerals.

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

[0009]

[Effect of device]

 According to the present invention described above, the wear of the bucket can be prevented and the service life can be extended by the wear-resistant steel plates and the excavated earth and sand pressed into the holes. In addition, by providing holes, the wear-resistant steel plate becomes lighter, and by excavating earth and sand in each hole, the wear area of the wear-resistant steel plate due to the earth and sand during excavation is reduced, and the wear-resistant steel plate itself The property is also improved.
