Description

Technical Field

[0001] The utility model belongs to the technical field of excavating equipment, in particular to an excavator bucket tooth. Background Art

[0002] The bucket tooth of an excavator is one of the most important components in excavation operations. It directly bears the impact, cutting and extrusion of materials such as soil and rocks. For example, a single-hook bucket tooth disclosed in patent application number CN202223055857.2 includes a bucket tooth body, which includes a tooth tip, a middle part and a mounting part. The middle part is located between the tooth tip and the mounting part. The tooth tip, the middle part and the mounting part are integrally formed. A wear-resistant strip is installed between the middle part and the tooth tip.

[0003] During use, the bucket teeth of this existing excavator are easily subjected to excessive impact and vibration. The vibration of the bucket teeth will also be transmitted to the connecting part and the bucket, causing the bucket teeth to easily fall off and be damaged, thereby reducing the service life of the bucket teeth. At the same time, during use, the surface of the bucket teeth is also prone to material accumulation, which increases the working load, so it is necessary to make improvements. Utility Model Content
