Abstract

The invention discloses an excavator bucket tooth assembly convenient to replace. The excavator bucket tooth assembly comprises a tooth base and a bucket tooth. The bucket tooth comprises a tooth tip, a tooth body and four tooth plates. The front surface, the back surface, the left side surface and the right side surface of the tooth body are each provided with a second fixing hole. Second fixing nails are inserted into the second fixing holes to fix the four tooth plates to the tooth body. The tooth body is internally provided with a first cavity. The first cavity is internally provided with a sliding block. A communicating hole is formed between the first cavity and the back end of the tooth body. One end of a connecting rod is connected with the tooth base. The other end of the connecting rod penetrates through the communicating hole and is connected with the sliding block. A buffer spring is connected between the tooth base and the tooth body. The technical effects that only parts of the bucket tooth components need to be replaced, replacing is convenient, the replacing cost is low, and damage is not prone to occurring are achieved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an excavator bucket tooth assembly that is easy to replace. Background technique [0002] Excavator bucket teeth are important consumable parts on excavators, similar to human teeth, they are combined bucket teeth composed of tooth holders and bucket teeth, and the two are connected by pins. [0003] According to the environmental classification of excavator bucket teeth, excavator bucket teeth can be divided into rock teeth (for iron ore, quarry, etc.), earth square teeth (for digging soil, sand, etc.), conical teeth (for coal mine). Divided according to the bucket tooth seat: excavator bucket teeth can be divided into vertical pin bucket teeth, horizontal pin bucket teeth, and rotary bucket teeth. [0004] In the prior art, due to the working mode of the excavator, the working environment of the bucket teeth is harsh and the working intensity is high. After a period of use...
