Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a drilling rig facilitating bit replacement. Background Technique

[0002] A drilling rig is a mechanical device that drives a drill string to drill underground in exploration or the development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.) to obtain physical geological data. Its main function is to drive the drill string to break the rock at the bottom of the hole, lower or lift the drill string in the hole. When drilling underground, substances such as rocks that are relatively difficult to drill through are often encountered. After long-term operation, the drill bit is prone to wear and damage and needs to be replaced in a timely manner.

[0003] The existing drill bits are usually fixed to the drilling rig through threaded grooves or inserted at the top. When the drill bit needs to be replaced, it is necessary to manually rotate or pull out the drill bit, which is time-consuming and laborious. Moreover, when the drill bit is working underground, a large amount of mud will adhere to the surface of the drill bit. If the drill bit is not flushed in a timely manner, the drilling efficiency of the drilling rig will also be reduced. Therefore, this patent proposes a drilling rig facilitating bit replacement to solve such problems. Content of the Utility Model
