A deep rock automatic sampling device for geological exploration

Abstract

The invention discloses an energy-saving and environment-friendly automatic deep rock sampling device for geological prospecting, belonging to the technical field of deep rock geological prospecting. The technical scheme of the invention is as follows: the energy-saving and environment-friendly automatic deep rock sampling device for geological prospecting comprises a support frame, and an opening is formed in the bottom of the support frame; the support frame is internally and respectively provided with a powder driving mechanism, a drilling mechanism and a limiting mechanism arranged at one side of the drilling mechanism. The energy-saving and environment-friendly automatic deep rock sampling device has the beneficial effects that ground rock debris and mud are automatically transmitted to a mud inlet and a mud outlet together so as to be discharged while automatic drilling and automatic mud feeding of the deep rock are lubricated; the device is environmentally-friendly and energy-saving, overcomes the waste of rock and mud caused by the fact that the rock debris and mud permeate into a surrounding foundation pit in a process of pumping out the rock debris and mud by a traditional outer circulation way, and solves the problem that the health of workers is influenced by the air pollution caused by the rock debris and mud which suspend in the air due to dryness when reaching the earth surface.

Description

technical field [0001] The invention relates to the technical field of deep rock geological exploration, in particular to an automatic deep rock sampling device for geological exploration. Background technique [0002] In geological exploration, drilling methods are often used to observe the natural state of rock and soil layers and the geological structure of each layer. Drilling refers to the use of drilling rigs to drill holes in the layers to identify and divide subsurface layers, and to take samples along the depth of the drill holes. A method of exploration that yields deep geological data. When drilling the formation, the function of the mud is very important. It can suspend and carry cuttings, balance the formation pressure, help the drill bit to break the rock, and cool the drill bit and drilling tools. [0003] In the existing drilling, the mud feeding process is to pour the mud powder into the container, and then transport the mud powder to the mud tank through t...

Problems solved by technology

[0003] In the existing drilling, the mud feeding process is to pour the mud powder into the container, and then transport the mud powder to the mud tank through the action of the centrifugal pump, and make the mud liquid through the stirring action of the agitator in the mud tank, and then put the mud powder into the mud tank. Under the action of the vacuum pump, the mud is injected into the drill bit to cool the drill bit. The external circulation of mud injection and extraction not only wastes mud resources, but also increases the labor intensity of workers. The waste of rocks and mud caused by the infiltration of mud and mud into the surrounding foundation pits, and the air pollution caused by the drying and suspension of rock chips and mud in the air when they reach the surface affect the health of workers
