Hydraulic Hard Rock Drilling Machine With 200m Drilling Depth Automatic Feed GK200

Hydraulic GK200 Core Drilling Machine / Mining Exploration Borehole Drilling MachineThis small borehole drilling machine is widely applied for geology general check exploration, earth physics exploration, road and high layer building ground survey, water bore well, blast opening, and various drilling engineering applications.

• Hydraulic automatic feed mechanism improves drilling efficiency and reduces manual labor
• Card holder mechanism replaces ball chuck, enabling non-stop down lever operation
• Bottom hole pressure gauge indicates pressure for easy hole situation monitoring
• Centralized handles for convenient operation
• Light weight with strong decomposition for easy transportation
• Suitable for plains or mountain areas
• Compact structure with drill, water pump and diesel engine installed on one base frame
• Safe and reliable operations

• General geological investigation
• Geophysical exploration
• Highway and building construction
• Blast-hole drilling
• Water bore well drilling

The drill pipe is fixed on the main winch drum through the steel wire rope, and the drill pipe can be raised or lowered accordingly when the drum is wound or released with the steel wire rope. The power of the drum comes from the main winch motor that has been decelerated for multiple times.

During lifting or lowering operations, if the operating handle is returned to the middle position and the drill pipe cannot stop quickly, there may be three potential causes:

• Brake lag
• Failure of the two hydraulic locks at the motor outlet, preventing immediate motor stop under wire rope torque
• Delayed disconnection of solenoid valve 2, which connects oil inlet and outlet pipes during drill pipe release function operation
