High-abrasion-resistance excavator bucket tooth with external chilling reinforcing ribs
The invention provides a high-abrasion-resistance excavator bucket tooth with external chilling reinforcing ribs. The excavator bucket tooth comprises a bucket tooth body and the external chilling reinforcing ribs arranged on the front side and the rear side of the bucket tooth body. The bucket tooth body comprises an installing region, a working region and a tooth point. The chilling reinforcing ribs are multiple cylindrical structures distributed in longitudinal columns and parallel to the length direction of the bucket tooth, a cutting bevel is arranged at the position, close to the tooth point, of each chilling reinforcing rib, the chilling reinforcing ribs are solidified preferentially in the casting and solidifying process of the bucket tooth and form a chilling effect on the bucket tooth body on the inner side to promote grain refinement of the bucket tooth, and the tissue is more uniform, so that the bucket tooth has higher rigidity and better shock resistance in the excavating process and is effectively prevented from being damaged by a hard object, and the passing performance of excavating and the abrasion resistance of the bucket tooth are improved. The bucket tooth is simple in structure, capable of improving excavating efficiency and reducing energy consumption of a machine and wide in application range, and the service life of the bucket tooth is prolonged.
