Abstract

The invention provides a drilling device for geological exploration. The drilling device is applied to drilling operation in geological exploration so as to ensure the drilling efficiency and prevent rock fragments from blocking a drill bit water outlet hole and drill rods. The drilling device comprises a drill bit, an anti-blocking rod, a first drill rod and a plurality of second drill rods, wherein a cutting edge is arranged at the end part of the first end of the drill bit; the first end of the anti-blocking rod is in threaded connection with the second end of the drill bit; the first end of the first drill rod is in threaded connection with the second end of the anti-blocking rod; an auxiliary rod is arranged on the periphery of the first drill rod; a cutting edge is arranged at the end part, close to the anti-blocking rod, of the auxiliary rod; the second drill rods are arranged in sequence; the second drill rods positioned at the end parts are in threaded connection with the first drill rod; AND the first drill rod, the second drill rods, the anti-blocking rod and an inner cavity of the drill bit communicate. The drilling device can ensure the drilling efficiency and prevent the rock fragments from blocking the drill bit water outlet hole.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a drilling device for geological exploration. Background technique [0002] Geological prospecting is the investigation and research activity of conducting geological exploration and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. In order to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, conduct investigations on rocks, strata, structures, minerals, hydrology, landforms and other geological conditions in a certain area research work. Geological exploration is also required before coal mining operations, and holes are drilled to facilitate ...
