D-Shaped Drilling Bucket

The D-shaped drilling bucket is a drilling tool specially used for drilling and dredging sand by rotary drilling rigs under complex geological conditions. With its unique D-shaped structure and specially designed bucket teeth, it can effectively work in silt layers, soil layers and other strata that are prone to shrinkage and collapse, improve drilling efficiency, and prevent shrinkage and collapse.

Features of D-Shaped Drilling Bucket

Structural design: The D-shaped drilling bucket usually adopts a cylindrical structure connected by two straight plates and two arc plates. This design can prevent rolling during transportation and reduce the risk of damage to the kelly bar and drill bit.
Applicable formations: Especially suitable for formations such as silt layers and soil layers that are prone to shrinkage and collapse, which can effectively avoid the problem of shrinkage caused by lifting the drill.
Efficient soil unloading: During the lifting process of the D-shaped drilling bucket, the pressure rod mechanism on the upper part of the D-shaped drilling bucket is pushed open by the drilling rig pressure plate, so that the bottom plate of the D-shaped drilling bucket hung by it is opened, so as to quickly unload the mud and sand in the cylinder.
