Drill bit seat of drilling machine

Abstract

The invention discloses a drill bit seat of a drilling machine. A top plate is included. A transparent cylinder is fixed at a bottom of the top plate. A mounting base is arranged in the transparent cylinder. A plurality of mounting threaded holes with different hole diameters are arranged in an outer wall of the mounting base. A drill bit is in threaded connection with a mounting threaded hole ina bottom end of the mounting base. A left side and a right side of the mounting base are provided with fixing plates respectively. A sliding groove and a limiting guide rail are arranged on the innerside of each fixing plate. Grooves are arranged in the outer walls of the left side and the right side of the mounting base. A rotating shaft penetrates through the mounting base. Two ends of the rotating shaft are rotatably connected with sliding blocks. The sliding blocks are arranged in the sliding grooves of the corresponding fixing plates in a sliding mode. A plurality of fixing rods which are evenly distributed in a circumferential direction are arranged in the groove in a circumferential side of the rotating shaft, the fixing rods are matched with the limiting guide rails, and a supporting rod is connected between the top of each fixing plate and the bottom of the top plate. In the invention, the drill bit is conveniently and rapidly replaced and fixed, and different drilling requirements are conveniently met.

Description

technical field [0001] The invention relates to the technical field of drill bit holders, in particular to a drill bit holder for a drilling rig. Background technique [0002] A drilling rig is a complex set of machines, which consists of machines, units and mechanisms. A drilling rig is a mechanical device that drives a drill bit to drill underground to obtain physical geological data during exploration or mineral resource development, also known as a drilling rig. The main function is to drive the drilling tool to break the rock at the bottom of the hole, and the drilling tool that is lowered or raised in the hole can be used to prove the underground geology and mineral resources. [0003] The drill bits of the existing drilling rigs are complicated to replace and cannot be suitable for the installation and fixing of various types of drill bits; meanwhile, due to the difficulty in fixing the drill bits in the existing drilling rigs, the positioning accuracy of the drill b...

Problems solved by technology

[0003] The drill bits of existing drilling rigs are complicated to replace and cannot be suitable for the installation and fixing of various types of drill bits; at the same time, due to the difficulty in fixing the drill bits in the existing drilling rigs, the positioning accuracy of the drill bits is poor, which affects the actual work of the drill bits
