Spiral guider of water-exploring drilling machine

The utility model provides a spiral guider of a water-exploring drilling machine and belongs to the technical field of underground water exploration and drainage. The spiral guider mainly solves the problem that a guider in the prior art will cause blockage by rock powder and even an accident. The spiral guider of the water-exploring drilling machine comprises a guider body and is characterized in that the outer surface of the guider body is provided with a spiral protrusion in the length direction; one end of the guider body is provided with external threads, and the other end of the guider body is provided with internal threads. The spiral guider reduces an annular gap, effectively controls the deflection of a drilled hole and improves the hole deflection control effect; with respect to a fault fracture zone and other geologic structure zones, the rock powder can be discharged easily; the rock powder discharge path is expanded, and the drilling efficiency is improved.
