Abstract

The utility model discloses a geological drill pipe comprising a drill pipe body, wherein the center of the drill pipe body is provided with a water through hole; a female connector with an internal thread is welded at the tail part of the drill pipe body; a male connector with an external thread is welded at the front part of the drill pipe body; and the centers of the male connector and the female connector are respectively provided with a water through hole. The female connector is used for being connected with the male connector of the former section of drill pipe or a drilling machine, and the male connector is used for being connected with the next section of female connector or a drill bit. Screw threads of the male connector and the female connector are both taper threads which are conveniently connected and disconnected. One section of the peripheral part of the female connector is of a tetrahedron to facilitate clamping the drill pipe and connecting the screw threads. The geological drill pipe is convenient to machine, rapid in drilling, high in efficiency, higher in fatigue resistance and longer in service life.

Description

Geologic drilling rod
Technical field
The utility model relates to a kind of geologic drilling rod, mainly is applicable to geology, the hydrology, coalfield, underground heat, engineering drilling mine.
Background technology
Traditional geologic drilling rod is the ordinary steel overall structure, and this drilling rod is totally oversize, and two ends threaded portion engine lathe can't be processed, and difficulty of processing is large, and machining accuracy is difficult to guarantee, and two ends threaded portion frangibility, and application life is short.
Summary of the invention
The purpose of this utility model provides a kind of geologic drilling rod, solves the existing large problem of geologic drilling rod difficulty of processing.
The purpose of this utility model realizes as follows: this geologic drilling rod, comprise the drilling rod body, there is the limbers at drilling rod body center, and the welding of drilling rod body afterbody is with the female joint of internal thread, the anterior welding of drilling rod body is with externally threaded male joint, and all there is the limbers at the center of male joint and female joint.Female joint is used for being connected with male joint or the rig of upper joint drilling rod, and male joint is used for being connected with female joint or the drill bit of lower joint.
The screw thread of male joint and female joint is taper thread, the convenient connection and dismounting.
The outer peripheral portion of female joint has one section to be tetragonal body, conveniently blocks the drilling rod connecting thread.
The convenient processing of the utility model is crept into fast, and efficient is high, and higher fatigue resistance and long life-span are arranged.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, a drilling rod body 2 is arranged, there is limbers 3 at drilling rod body 2 centers, the welding of drilling rod body 2 afterbodys is with the female joint 4 of internal thread, the 2 anterior welding of drilling rod body are with externally threaded male joint 1, all there is the limbers at the center of male joint 1 and female joint 4, and the screw thread of male joint 1 and female joint 4 is taper thread.The outer peripheral portion of female joint 4 has one section to be tetragonal body.
