Abstract

The invention provides a drill bit for geological exploration, which relates to the technical field of drill bit structure, including a drill pipe body, a stamping drill bit assembly, a crushing drill bit assembly and a reaming drill bit assembly; since the stamping drill bit assembly is arranged at the bottom end of the drill pipe body, The rock and soil can be broken in advance by using the impact force of the impact drill bit assembly. On the basis of the rock and soil crushed by the impact drill bit assembly, the drill pipe body drives the crushing bit assembly to rotate to form a primary well hole in the rock and soil. After forming the primary well hole Basically, the drill pipe body drives the reaming bit assembly to rotate, expand the size of the primary well hole, and finally obtain a well hole that meets the requirements; based on the above, through the cooperation of the percussion bit assembly, the breaking bit assembly and the reaming bit assembly, the The drill bit in this application has three functions of rock-soil crushing, preliminary hole forming and hole reaming. On the basis of rock-soil crushing, drilling and reaming are carried out sequentially. long.

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...
