Core drill rig   Core drilling rig is a professional drilling equipment used in geological exploration, mineral exploration and other fields, mainly used to extract rock samples to understand the properties, structure and geological conditions of underground rocks.     Classification of core drilling machines   -According to the driving method, there are hydraulic drive, electric drive, and mechanical drive. Hydraulic driven drilling rig has strong power and wide speed range; Electric driven drilling rig runs smoothly and has low noise; The mechanical driven drilling rig has a simple structure and low cost. -According to the drilling method, it can be divided into rotary, impact, and vibration types. Rotary drilling machines are the most widely used, cutting rocks by rotating the drill bit; The impact drilling rig uses impact energy to break rocks and is suitable for hard formations; A vibrating drilling rig breaks rocks through vibration and is commonly used in so…
