Standard of Working Condition of Bucket Teeth
The whole process of excavator excavation is that the bucket tooth tip takes the push key as the starting point for rotating fitness movement, and the track of the tooth tip is the majority of vortex lines.
The key role of bucket teeth is:
1. Separate the material.
The blade of bucket teeth first touches with minerals and separates the material, and the guiding effect is easy to load the bucket.
The friction resistance of the newly installed bucket teeth is 10 ~ 25% less than that of the non-bucket teeth.
2. Maintain the front wall of the bucket.
In the excavation, the chisel damage caused by the impact of the material on the bucket teeth continues to reduce the size of the bucket teeth, thus maintaining the front wall of the bucket and increasing its service life.
In China, the standards of ore and rock mining are complex, which are mainly manifested in the wide variation of strength of ore and rock, such as iron ore F = 10-20, rock F = 10-18;
In mining, if the lump rate is high and the foundation is many, the load of bucket teeth is improved.
The load borne by the bucket teeth of the domestic pedal-type excavator is very impact load, which is far more than that of the hydraulic excavator. The raw material and structure of the bucket teeth have a higher bearing capacity and the working ability of chipping damage under high in-situ stress
