Abstract
Provided is a novel wear-resistant and collision-resistant polycrystalline diamond compact (PDC) drill bit with rostriform teeth and a plurality of blades, including an upper joint and a drill matrix. The PDC drill bit with rostriform teeth and a plurality of blades breaks rocks jointly by the primary teeth by way of penetration-splitting and the secondary teeth by way of shearing, so that the torque needed to break the rocks is greatly reduced. The design of the plurality of blades balances force distribution between rocks and blades at a shaft bottom, so that the abrasion loss of the teeth within a unit time is reduced. The present invention solves the technical problems in the prior art that cutting positions are abraded, and the teeth are fed slowly and are unreasonably distributed.
