Abstract:
The invention discloses a high-speed drilling bit, comprising a drill bit rigid body and drill teeth installed above the rigid body. The exterior surface of the drill bit rigid body is sleeved with an annular cylinder, which has grooves and water channels on its outer surface. Groove teeth are located in the grooves, and the inner surface of the annular cylinder has connection slots that match with connection axles on the exterior surface of the drill bit rigid body. The top surface of the drill teeth is equipped with raised excavation wings, and the groove teeth are triangular prism-shaped, evenly distributed in a stepped fashion within the grooves. The sides of the drill teeth are equipped with drilling edges, and the top side of the drill bit rigid body is curved. The top of the drill bit rigid body has several water permeation holes extending to the side of the bit, and the raised excavation wings have a rough texture. The configuration of an annular cylinder on the outer surface of the drill bit rigid body, with grooves and water channels, and groove teeth within the grooves, allows effective clearance of blockages caused by mud and sand, ensuring continuous operation of the drill bit.
