Drill bit holder

Abstract

The invention discloses a drill seat for a drilling rig, comprising a top plate, a transparent cylinder is fixed on the bottom of the top plate, a mounting seat is provided inside the transparent cylinder, and a plurality of mounting threads with different apertures are provided on the outer wall of the mounting seat. hole, a drill bit is threadedly connected to the mounting threaded hole at the bottom of the mounting seat, a fixing plate is provided on the left and right sides of the mounting seat, and a slide groove and a limit guide rail are respectively provided on the inner side of the fixing plate. The outer walls of the left and right sides of the seat are respectively provided with grooves, and a rotating shaft passes through the inside of the mounting seat, and a slider is connected to both ends of the rotating shaft in rotation, and the slider is slidably arranged in the chute of the corresponding fixed plate, so that A plurality of fixed rods uniformly distributed around the circumference are provided inside the groove on the side of the rotating shaft, and the fixed rods are matched with the limit guide rails, and a support rod is connected between the top of the fixed plate and the bottom of the top plate. , It is convenient for quick replacement and fixing of the drill bit, which is convenient to meet different drilling needs.

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...
