The bucket teeth of the excavator are so selected that the wear resistance...

Bucket teeth, which are common in the market, are classified according to the scope of application:

1. Earthwork teeth (used for excavating soil, sand, gravel and other light working environment) generally, the earthwork teeth are matched with the bucket with large bucket mouth area, which has a large stacking surface, so it has a high filling coefficient, saves operation time and high efficiency.

2. Rock teeth (used for ore and stone ore) are used for ore loading after blasting, heavy operation strength wear-resistant steel, better excavation performance and more prominent economy.

3. Conical teeth (used for mining of coal mines and geological mines) are mainly suitable for drilling rock layers with low hardness and have great impact.

Bucket teeth installation

Common installation methods include straight mounted bucket teeth and horizontal mounted bucket teeth,

Direct installation means that the pin shaft is installed vertically with the front of the digging bucket teeth,

Horizontal installation means that the pin shaft is installed parallel to the front of the digging bucket teeth.

Straight mounted bucket teeth:

It is convenient to disassemble. It can be smashed directly from above and has a large operation space.

During excavation, the directly installed tooth pin will be squeezed by the excavated materials. If the excavation force is large, the clamping force of the expansion spring can not meet the requirements, which is easy to cause the tooth pin to fall off. Therefore, although this structure is easy to disassemble, it is generally used on excavators with small excavator and low tonnage.

Horizontal bucket teeth:

It is not very convenient to disassemble, the side operation space is small, and it is difficult to awesome. When disassembling a single bucket tooth, special long rod tools must be used in sequence.

During excavation, the front face of the transversely mounted gear pin will not be squeezed by the excavated materials and can bear a large excavation force. However, when the expansion spring is subjected to the reciprocating lateral force in use, it is easy to wear and fail, resulting in the falling off of the gear pin. Generally, it is more common when the excavation force is more than 20 tons.
