Description

Technical Field

[0001] The utility model belongs to the technical field of bucket teeth, and in particular relates to a wear-resistant bucket tooth. Background Art

[0002] Bucket teeth are important parts of excavators. They are similar to human teeth and are also consumable parts. They are composed of tooth seats and tooth tips, which are connected by pins. During excavation, each working surface of the bucket teeth contacts the excavated material, and its force conditions change with different stages of the excavation process. As the excavation depth increases, the force conditions of the bucket teeth will change. When the bucket teeth cut the material, there is relative movement between the bucket teeth and the material, which generates a lot of friction. If the material is a rock block or concrete with a high hardness, the friction will be very large. The result of this process is repeated, resulting in different degrees of surface wear on the working surface of the bucket teeth, which in turn generates deep furrows and causes the bucket teeth to be scrapped. Therefore, the quality of the wear-resistant layer on the surface of the bucket teeth directly affects the service life of the bucket teeth.

[0003] The utility model with application number CN201320228525.1 discloses an excavator bucket tooth with a convex point layer, including a bucket tooth body, a protective layer arranged on the outer edge of the bucket tooth body, a protective convex block arranged on the upper end of the bucket tooth body, the protective convex block is arranged on the bucket tooth body in an inverted trapezoidal shape, a convex point layer is arranged on the bucket tooth body, and spurs are arranged on the convex point layer. The length of the convex point layer decreases from top to bottom. The purpose of the utility model is to design an excavator bucket tooth with a convex point layer. The protective layer arranged on the bucket tooth body effectively protects the service life of the bucket tooth and makes it more wear-resistant. The convex point layer arranged on the bucket tooth body can keep the bucket tooth sharp. The utility model has a simple structure and a long service life. The bucket teeth in the utility model are easily worn or deformed and damaged after long-term use, and need to be disassembled and replaced. The disassembly and assembly of the bucket teeth are cumbersome, and the replacement efficiency is low. Utility Model Content
