Multifunctional reamer for geological prospecting

Abstract

The invention discloses a multifunctional reamer for geological prospecting. The reamer comprises a drill pipe, a drill bit, three spiral reamer plates and a fixing band; an impactor is fixed on the upper portion of the drill pipe, the fixing band is fixed on the lower portion, close to the drill bit, of the drill pipe, three rotating shafts are uniformly fixed on the edge of the fixing band, each spiral reamer plate is rotatably connected with the fixing band through the corresponding rotating shaft, the portions, close to the fixing band, of the upper portion and the lower portion of the internal surface of each spiral reamer plate are connected with the drill pipe through telescopic cross rods, a compression spring is installed in each telescopic cross rod, protruding blocks are uniformly welded to the outer surface of each spiral reamer plate, and a dust cover is rotatably connected to the portion, above the impactor, of the drill pipe through a thread. According to the multifunctional reamer for geological prospecting, the structure is simple, the reaming effect is rapid and significant, time and labor are saved, the functions of achieving reaming and discharging mud and gravel to prevent blocking and dust are achieved simultaneously, and the multifunctional reamer is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of geological exploration equipment, and in particular relates to a multifunctional geological exploration hole reamer. Background technique [0002] "Geological exploration" means to survey and detect the strata through various means and methods, determine the thickness of different strata, take core samples of rocks in different strata, and then determine the chemical and physical properties of rock minerals through testing and mechanical analysis. For mineral deposits with industrial significance found 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, strata and structures in a certain area , mineral resources, hydrology, geomorphology and other geological conditions to carry out ...

AI Technical Summary

Problems solved by technology

[0003] The reamer is a commonly used reaming tool in geological exploration. There are many types of reamers on the market, such as: barrel reamers, rock reamers, etc. These reamers are large in size and low in drilling efficiency. The parts are very vulnerable, and the cutting power for soil and rock is insufficient. There are large pie
