Excavator bucket tooth is the main vulnerable component of excavator, similar to human teeth, is composed of tooth seat and tooth tip, the two by the pin shaft, because the bucket tooth wear failure part is tooth tip, as long as the tip can be replaced.

According to the bucket tooth seat. The bucket teeth of excavator generally have two structural forms, respectively direct and horizontal. Direct installation refers to the vertical installation of the pin shaft to the front of the excavation tooth; horizontal installation refers to the parallel installation of the pin shaft to the front of the excavation tooth.

Direct installation type: more convenient when disassembly, directly hit from the above, the operation space is large. When digging, the directly installed tooth pin will be under the extrusion pressure of the excavated material. If the digging force is large, the tension force of the rising spring cannot meet the requirements, which is easy to cause the tooth pin to fall off.

So the direct installation type is generally used in the excavator smaller, lower tonnage excavator.

Horizontal type: it is not convenient in disassembly, the side operation space is small, and it is difficult. When removing a single bucket tooth, you must use special long rod tools in order. When digging, the front of the transverse tooth pin will not be subjected to the extrusion pressure of the excavated material, and can bear the excavation force. However, when the rising spring is subjected to the reciprocating lateral force in the use, it is easy to wear and fail, resulting in the loss of the tooth pin.

So the horizontal type is generally used in the excavation force of more than 20 tons of the excavator.

Environmental classification according to the use of excavator bucket teeth. Excavator bucket teeth can be divided into rock teeth (used for iron ore, stone ore, etc.), earth teeth (used for digging soil, sand, etc.), and conical teeth (used for coal mine). But the bucket tooth shape of different brands of excavators also has their own characteristics.
