Kqd Hand Hole Digging Tools Small Electric Pneumatic Rock Drill/Water Well Drilling Machine

Portable Small Slope Protection DTH Drilling Rigs: Affordable, efficient, and ideal for a wide range of geotechnical applications.
1, Brief Introduction:
The KDQ series pneumatic DTH drilling rig is a versatile and reliable solutionfor road construction, national defense projects, water conservancy, large stone projects, and slope protection. Ideal for small blasthole drilling.This rig is exceptionally useful in rugged and uneven terrains where other DTH rigs struggle. Featuring a compact structure, user-friendly operation, fast drilling speeds, high efficiency, easy disassembly, and convenient portability.

2. Features:
(1) Suitable for various types of down-the-hole impact with high rock drilling efficiency.
(2) Powered by compressed air for single-source, safe, and reliable operation.
(3) Simple structure, easy to operate, short auxiliary time, and lightweight design.

1. Working Principle
   The rig operates using compressed air to convert it into mechanical force to break rocks. It is equipped with a hammer and bit.
   During operation, the piston's continuousimpacts on the bit's tail allow the alloy teeth to continuously break the rock. Therotating torque generated by the reducer rotates the drilling tool and propelsthe axial force from the cylinder, driving the drill into the ground.
2. 4. Structural Characteristics
3. This down-the-hole drilling rig comprises a powerhead assembly (including a speed reducer and a pneumatic motor), a propulsion cylinder assembly, a control console with an oil lubricator and pressure gauge, a hammer, and a bit.
   5. Operating Procedures
   (1) Preparation for Transportation
   (1) After transporting the drilling rig to the site, inspect all components for defects and then assemble and refuel.
   
   (2) Position the front legs of the carriage at the working site and adjust the support rod to set the carriage angle.
   
   (3) Before connecting the motor and hose, clean the hose thoroughly. Open the pipeline valve for a few seconds to blow away any foreign matter with compressed air.
   (4) Check all bolt connections for tightness and ensure there are no leaks in the pipelines.
   (5) Fill the oil mister with an appropriate amount of 30# oil.(6) Set all pneumatic control valve handles to the 'stop' position.
   
   Once preparation is complete, conduct a no-load test to ensure functionality.
