Rotary Drill Rig B47K Teeth Drilling Rock Core Barrel Bucket
Application:
1.When rotating, the drill core of the core rock drill has several different cutting angles that are matched with each other, and it is repeatedly broken and knocked at the position of the ring groove in the hole.
2.Fractured rocks and hard rocks that the hardness is less than 80 MPa, relatively hard bedrock formations, large boulder layers and hard permafrost layers.
Feature
1.Cutting ring with rock drilling bits and releases the internal stress of rock;
2.Rock drilling bits perform stage breaking and drilling;
3.Small barrel facilitates the coring operation, large barrel performs stage breaking;
4.Barrel adopts spiral wear resistant strips ,anti-attrition,prolong service life.
5.Heightening design,high construction efficiency ,efficiency reduce construction cost.
