Geological drill rod

Abstract

The invention discloses a geological drill rod, comprising a drill rod body and a first spring, wherein one side of the drill rod body is fixedly connected with a male connector, the other side of thedrill rod body is fixedly provided with a female connector, water passing tanks are formed inside the drill rod body, the male connector and the female connector, one end, away from the drill rod body, of the male connector is fixedly provided with a connecting head, fixing rod grooves are formed in the middles of two sides of the connector, the first spring is located inside the fixing rod grooves, the first spring is connected with a fixing rod at a place close to an opening side of the fixing rod groove, a control system is arranged inside the drill rod body, the male joint drives the connecting head into the interior of a connecting groove, when the connecting head drives the fixing rod to reach the position of a fixing groove, the first spring pushes the fixing rod into the interiorof the fixing groove, the connecting head is prevented from moving out of the connecting groove, so that the male connector is fixedly connected to the female connector through the connector, and whenthe male connector drives the female connector to rotate through the connecting head, damage to the fixing rod is avoided.

Description

technical field [0001] The invention relates to the technical field of drill pipes, in particular to a geological drill pipe. Background technique [0002] Geological drill pipes are mainly suitable for drilling mines in geological, hydrological and coal fields. Most of the existing geological drill pipes are produced and processed by advanced friction welding welding technology. The drill pipes have the characteristics of high bending strength and firm welding. [0003] Although there are many kinds and quantities of present geological drill pipes, certain problems still exist in the existing geological drill pipes, which bring certain inconvenience to the use of geological drill pipes. [0004] When the existing geological drill pipes are in use, the male joint and the female joint are mostly connected by threads. However, when the drill pipe encounters resistance when the drill pipe is rotating, it needs to rotate in the opposite direction, so that the male joint and the ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of geological drill pipe, to solve the problem that the current geological drill pipe proposed by the above-mentioned background technology is used. If it encounters resistance, it needs to be rotated in the opposite direction, which is easy to separate the male joint from the female joint, and in order to facilitate drilling into the ground, it is necessary to set up a water channel in the drill pipe. When drilling underground, the soil can easily enter the interior of the water channel, so that The sink is blocked, making it inconvenient to use
