Description

Tricone bit

Technical Field

The utility model relates to the technical field of drill bits, in particular to a tricone bit.

Background

The drill (zu aint ou u) is a tool for drilling through holes or blind holes in solid materials and reaming the existing holes. Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills. Reamers and reamers are not capable of drilling solid materials, but they are also traditionally classified as drills.

During digging, the drill bit rotates along with the vertical shaft and moves axially. The soil is cut under the action of torque and axial force of the drill bit, loosened under the action of extrusion and centrifugal force of the working blades, pressed to the pit wall by formed soil flow, and lifted to the ground along the page. When the soil flow moves to the position without pit wall blocking, the broken soil is thrown to the periphery of the pit due to the centrifugal force, and the pit digging process is completed.

In the prior art, when a rock body with high hardness is faced, a common drill bit cannot perform rapid pit digging operation, and the common drill bit is often damaged.
