Abstract

The invention provides a drill bit for geological exploration, and relates to the technical field of drill bit structure. The drill bit for geological exploration comprises a drill pipe body, a punchdrill bit assembly, a crushing drill bit assembly and a reaming drill bit assembly. According to the drill bit for geological exploration, since the punch drill bit assembly is arranged at the bottomend of the drill pipe body, the rock and soil can be crushed in advance by using the impact force of the punch drill bit assembly, on the basis of the rock and soil crushing by the punch drill bit assembly, the drill pipe body drives the crushing drill bit assembly to rotate, a primary well hole is formed in the rock and soil, on the basis of forming the primary hole, the drill pipe body drives the reaming drill bit assembly to rotate, expanding the size of the primary well hole is carried out and finally the well hole meeting the requirements is obtained; and in summary, through the cooperation of the punch drill bit assembly, the crushing drill bit assembly and the reaming drill bit assembly, the drill bit has three functions of rock and soil crushing, preliminary hole forming and hole expanding, drilling and hole expanding are carried out successively on the basis of rock and soil crushing, the function is powerful, the wear degree of the drill bit in one use is less, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a drill bit for geological exploration. Background technique [0002] Geological prospecting is a general term for geological prospecting and detection through various means and methods. The main purpose of geological prospecting is to obtain information on mineral resources stored underground, such as coal, oil and natural gas reserves, or to obtain geological data, such as rock formations. structure, hydrology and geomorphology. [0003] The most widely used method in geological exploration is drilling, that is, drilling through drilling equipment, so as to intuitively obtain the profile of the stratum or the reserves of mineral resources. Among them, the drill bit for geological exploration is among the more important parts of the drilling equipment. The traditional drill bit assembly has a simple structure and relatively single function, which is easy to be damaged and ha...
