The invention relates to the technical field of drill rods, in particular to a rotary drilling machine drill rod with an adjusting mechanism, comprising: a drill bit, the top end of the drill bit is provided with a limiting ring, and the surface of the drill bit is provided with a cross recess; and the protective grains are arranged on the surface of the limiting ring, a mounting groove is formed in the surface of the limiting ring, a first drill rod body is fixedly connected to the bottom end of the drill bit, a positioning ring is arranged on one side of the first drill rod body, and a second drill rod body is arranged at the bottom end of the positioning ring. Through the design of a limiting ring and a mounting groove, a drill bit can be limited, a certain limiting effect is improved, stable operation can be guaranteed, when the second drill rod body is integrally drilled into the ground, the second drill rod body abuts against the ground through a positioning ring, an inserting rod can also rotate on the surface of the ground, and the drilling efficiency is improved. Therefore, the installation stability can be improved, a certain limiting effect is achieved, and the fixing effect is guaranteed.
Description
technical field [0001] The invention relates to the technical field of drill rods, in particular to a drill rod for a rotary drilling machine with an adjustment mechanism. Background technique [0002] The drill pipe is a steel pipe with threads at the end, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit, and raise and lower together with the drill bit Or rotating bottom hole device, the drill pipe must be able to withstand huge internal and external pressure, twisting, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used multiple times. The drill pipe is divided into kelly, drill pipe and weighted There are three types of drill pipes, bare pipes and raw steel pipes are made into drill pipes after multiple processing steps. Fi...
