Excavation tooth components, tooth holders and bucket teeth

Abstract

An excavation tooth assembly, a tooth seat and a bucket tooth. The excavation tooth assembly includes the tooth seat and the bucket tooth, and includes a locking member. A cavity is provided at the rear of the bucket tooth, and a tooth seat head is provided at the front end of the tooth seat. The cavity and the adapter head are firmly combined through the locking piece. The upper part of the adapter head is provided with a first transition connection surface, the first mating surface and the third mating surface, and the lower part of the adapter head is provided with a second transition connection surface , the second mating surface and the fourth mating surface, the first mating surface and the third mating surface are connected by the first transition connection surface, the second mating surface and the fourth mating surface are connected by the second transition connection surface, the first mating surface and the The second mating surface forms a predetermined angle with the central axis of the tooth seat head respectively, the third mating surface and the fourth mating surface are respectively parallel to the central axis of the tooth seat head, and the inner surface of the cavity of the bucket teeth provides Multiple mating surfaces in surface contact.

Description

technical field [0001] The invention relates to a excavating component in engineering machinery or mining machinery, in particular to a fixed connection structure between bucket teeth and tooth seats. Background technique [0002] Excavators, loaders, and mining machines in the field of construction machinery and mining machinery perform excavation or loading operations through buckets, and buckets play the role of cutting and loading materials. The bucket is subject to huge wear and tear, if no protective measures are added to its front end, it will be blunt or even damaged soon, and it is required to work efficiently for a long time, so in most cases it will be on the side of the bucket. The purpose of installing an excavating tooth assembly or a wear-resistant plate is: first, to protect the working end of the bucket from being worn prematurely and too quickly; second, to increase the sharpness of the front end of the bucket and enhance the cutting and loading capabilitie...

AI Technical Summary

Problems solved by technology

The first disadvantage is that once the spring leaf fatigues and fails during the excavation process, the bucket teeth will be lost. The second is that in order to ensure sufficient friction, the size interference between the spring leaf and the tooth seat hole is large, and the disassembly process needs to be knocked vigorously. click, inconvenient to install
