A combination device of a new buffer excavator gear seat and bucket teeth

Abstract

The invention discloses a combination device of a novel cushioning excavator gear seat and bucket teeth, which comprises a gear seat, bucket teeth, bayonet pins and shock absorbing pads, the tooth seat includes a tooth seat head and a tooth seat tail, and the tooth seat head Including the boss, the bayonet positioning seat and the excessive reinforcing rib, the boss, the bayonet positioning seat and the excessive reinforcing rib are integrally formed, the bayonet positioning seat is located at the end of the boss away from the head of the tooth seat, and the transitional reinforcing rib connects the boss The table and the tail are on the same side as the lower connecting plate. The bayonet pin is a hollow steel pipe structure. The inner wall of the bucket tooth installation cavity is fitted with the boss of the tooth seat head. The inner wall of the bucket tooth installation cavity is locked with the tooth seat head. There is a gap between the positioning seats, and the shock absorbing pad is directly poured on the inner cavity wall of a week where the bucket tooth and the boss of the head of the tooth holder fit together. The advantage of the present invention is that the improvement measures reduce the various forces generated between the tooth seat, bucket teeth, bayonet pins, foreign materials, blades, etc., increase the service life of the tooth seat, save material costs, and improve the work efficiency.

Description

technical field [0001] The invention relates to the technical field of excavator auto parts, in particular to a combination device of a novel buffer excavator tooth seat and bucket teeth. Background technique [0002] An excavator is an earth-moving machine that uses a bucket to excavate materials above or below the bearing surface, and loads them into transport vehicles or unloads them to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The traditional excavator gear seat is connected to the bucket tooth through bayonet pins. The bayonet hole will reduce the strength of the tooth seat. The assembly gap between the bucket tooth and the tooth seat will cause a rigid collision between ...

AI Technical Summary

Problems solved by technology

The traditional excavator gear seat is connected to the bucket tooth through bayonet pins. The bayonet hole will reduce the strength of the tooth seat. The assembly gap between the bucket tooth and the tooth seat will cause a rigid collision between the bucket tooth and the tooth seat when the excavator is working. , this position is the location with high incidence of tooth seat fracture failure; secondly, there is no transition part between the tooth seat convex part and the base, which is the second stress concentration part; at present, all the connecting welds between the tooth seat and the bucket blade are located in the tooth seat At the same time, due to the right-angle structure of the opening position of the tooth seat, the joint surface of the tooth seat and the blade plate cannot be completely fitted. When the bucket is excavated, the weld is not only impacted, but also subject to material friction. Extends to the entire blade, causing damage to the entire bucket; not only wastes material, but also affects the construction period
