DTH Drill PipeWhat are the technological principles of the drill pipe?

With the continuous development of industry, people have more and more tools on hand. More and more abundant, in which the earth drill is a kind of active drill pipe commonly used by people, so what is his principle?DownDTH Drill PipeLet's talk about it:

In the design of the borrow drill, the main problem to be solved is how to reduce the resistance of the soil. Bearer cutting soil during sampling, by the soil on the drill cutting resistance, mainly including penetration resistance, friction, adhesion and so on.

The traditional method of reducing soil cutting resistance is to reduce the adhesion and cutting resistance by reducing the contact area between the soil and the drill bit, thereby reducing the soil resistance and achieving the purpose of reducing viscosity and resistance.DTH Drill PipeFoundThis method can effectively reduce soil resistance to a certain extent, but the effect is not ideal when encountering harder soil.

The methods of penetration, soil cutting, soil loosening, soil lifting and soil throwing are adopted to realize rapid soil collection. The earth-boring drill consists of a sleeve and a spiral drill pipe, and the blade end of the spiral drill pipe is made into a blade shape.DTH Drill PipeDuring sampling, the sleeve vertically penetrates into the soil under the action of hydraulic pressure, and at the same time, the auger drill pipe rotates to chop the soil, and the chopped soil is transported to the soil outlet at the top of the sleeve under the combined action of the blade and the sleeve. After the sleeve is raised, the soil directly enters the collection box through the hose under the action of gravity, thus completing the soil collection and collection.
