Concrete Core Barrel Bucket With Rock Drilling Teeth For Rotary Drill Rig

Concrete Core Barrel Bucket With Rock Drilling Teeth For Rotary Drill Rig

 

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.

3.Apply to obvious layered medium weathered sandstone (high probability of coring) hard rock cutting.

4.In higher compactness of soil or part of the soft rock strata,slippage due to selection of friction Kelly bar,can try to use core barrel.

 

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.

6.Adopts wear resistant block between teeth holders due to protect teeth holder and stiffening ring from serious wearing .
