Abstract

The invention relates to a rock-breaking PDC diamond drill bit. The drill bit comprises a body and at least three blades arranged on the body and used for fixed cutting; a bit leg is arranged betweenevery two adjacent blades; a cone is arranged on each bit leg; first cutting teeth are arranged on each cone; a main cutting layer is arranged on each blade; and a water spraying hole is formed in theside part of each blade. According to the rock-breaking PDC diamond drill bit provided, in the process of drilling into a hard stratum, diamond cutter particles are not prone to collapsing.

Description

technical field [0001] The invention relates to the technical fields of construction engineering and water conservancy engineering, in particular to a rock-breaking PDC diamond drill bit. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. [0003] In the process of water conse...
