Description

Technical Field

[0001] This utility model relates to the field of excavator bucket teeth technology, specifically a wear-resistant excavator bucket tooth. Background Technology

[0002] Excavator bucket teeth are crucial components of excavators, similar to human teeth, and are also wear parts. They are composite teeth consisting of a tooth base and tooth tips connected by a pin. Since the wear and failure of the bucket teeth occurs only at the tooth tips, simply replacing the tooth tips will resolve the issue.

[0003] However, existing excavator bucket teeth need to come into frequent and continuous contact with objects during actual use. When used with harder materials, this will cause accelerated wear of the excavator bucket teeth, which will lead to damage. Therefore, we propose a wear-resistant excavator bucket tooth.
