Drill bit with automatic gas detection function

Abstract

The invention belongs to the technical field of geological drill bits and particularly relates to a drill bit with an automatic gas detection function. The drill bit comprises a three-wing drill bit, wherein a bottom end of the three-wing drill bit is fixedly connected with a connecting plate connected with a clamping block in a clamping manner, a clamping groove is formed in a surface of the connecting plate, and a lower end of the three-wing drill bit is connected with a first connecting rod in a clamping manner; a bottom end of the first connecting rod is rotationally connected with a rotating module, an inserting hole used for controlling opening and closing is formed in a surface of the rotating module, by arranging the connecting plate and the rotating module, connection between the three-wing drill bit and the first connecting rod is more convenient and stable, mounting and dismounting are convenient, the limiting effect is good, operation is easy, and time is saved; the three-wing drill bit is prevented from falling off during use to affect normal use of equipment, use stability and convenience are improved, a first adjusting rack and a second adjusting rack are limited by arranging a sliding groove and a second adjusting rack, the first adjusting rack and the second adjusting rack can only stably slide in the direction of the sliding groove, the position is stable and accurate, and practicability is improved.

Description

technical field [0001] The invention belongs to the technical field of geological drill bits, and in particular relates to a drill bit with the function of automatically detecting gas. Background technique [0002] At present, there are many types of drill bits used in geological exploration. The drill bits are classified according to different drilling methods. They can be divided into diamond drill bits, roller cone drill bits and scraper drill bits. These three drill bits are the most basic drill bit forms. These three drill bits are one of the important tools for geological exploration. Whether the drill bit is suitable for rock properties and its quality plays a very important role in the selection of drilling technology, especially for drilling quality, drilling speed, drilling It has a huge impact on cost, which can effectively improve the service life of mechanical drilling tools, shorten the drilling cycle and reduce drilling costs. [0003] The original drill bit ...

AI Technical Summary

Problems solved by technology

[0003] The original drill bit with the function of automatic detection of gas is cumbersome to install and disassemble during use, it is inconvenient to replace the time-consuming angle, the limit is unstable and the operation is not convenient enough. Now a drill bit with the function of automatic detection of gas is proposed to solve the above problems
