Abstract

The invention discloses an alloy anchor bolt drill bit. The alloy anchor bolt drill bit includes a drill bit body, a connecting hole, a reinforcing rib, a water passing hole, a cutting head, a chip guiding groove, a clamping block, an adjusting bolt, a sliding groove and a bearing; the drill bit body is internally provided with the connecting hole, the reinforcing rib is fixed to the outer part of the drill bit body, and the cutting head is fixed to one end of the drill bit body; the water passing hole is formed in the middle part of the end, close to the cutting head, of the drill bit body; the water passing hole communicates with the connecting hole, and the chip guiding grove is formed in the outer part of the cutting head; a connecting opening is formed in the end, away from the water passing hole, of the drill bit body, and the connecting opening is located at the end, away from the water passing hole of the connecting hole; and the adjusting bolt is installed on the outer part of the connecting opening, the adjusting bolt penetrates through the wall of the connecting port, and the clamping block is slidably connected with the drill bit body through the sliding groove. The alloy anchor bolt drill bit is provided with a clamping mechanism for re-fixing a connecting rod, and the alloy anchor bolt drill bit is fixed through methods of screw connection and clamping connection.

Description

technical field [0001] The invention relates to the technical field of drill body drill bits, in particular to an alloy anchor drill bit. Background technique [0002] The main body of the drill bit is the most basic part of roadway support in contemporary coal mines. It binds the surrounding rock of the roadway together so that the surrounding rock can support itself. The main body of the drill bit is the drilling tool used in coal mines to fix the main body of the drill bit. . [0003] Although there are many types and quantities of alloy bolt bits on the market, most alloy bolt bits are only fixedly connected by a threaded connection, the connection effect is not good, and there is no good guarantee. Cutting has a large resistance, and the debris generated after cutting is not guided and exported, which will affect the production and processing process. Contents of the invention [0004] The purpose of the present invention is to provide a kind of alloy anchor drill b...
