Abstract

The invention belongs to the technical field of geological prospecting, and particularly relates to a multifunctional geological prospecting drilling device. The multifunctional geological prospectingdrilling device comprises a drill bit, a mounting plate is fixed to the top of the drill bit through bolts, a drill rod is welded to the top of the mounting plate, a cavity is formed in the drill bit, a baffle is arranged on the inner surface of the cavity, a sampling pipe is placed in the cavity, and a cushion block is welded to the outer surface of the sampling pipe. By arranging a motor, the motor drives the drill rod to rotate, the drill bit located at the top end of the drill rod can smoothly move downwards, at the moment, the sampling pipe mounted in the drill bit can collect related soil samples along with the penetration of the drill bit, and the other end of the sampling pipe extends to the top end of the drill rod; and an air outlet hole is formed in the top end of the drill rod, so that the sampling work is prevented from being influenced by air pressure in the sampling pipe, a worker can sample soil while hole drilling, the geological exploration steps of the worker are omitted, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a multifunctional geological exploration drilling device. Background technique [0002] Geological prospecting is an investigation and research activity that conducts geological exploration and detection through various means and methods, determines the appropriate bearing layer, determines the foundation type, and calculates the foundation parameters according to the foundation bearing capacity of the bearing layer. It is the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks and strata in a certain area. Conduct investigation and research work on geological conditions such as geolog...
