Key Features
- Compact Design: Lightweight construction ideal for high-altitude geological operations
- Hydraulic Feeding: Automatic feeding mechanism enhances drilling efficiency and reduces operator fatigue
- Robust Construction: Four vertical shaft boxes provide exceptional rigidity for challenging terrain conditions
- Patented Clutch: Taper clutch design offers high torque transmission with maintenance-free operation
Core Drilling Operation
The drilling system consists of three main components: drilling machine, drill pipe, and drill bit. The rig provides power to drive the drill pipe and bit, enabling deep core sample extraction for geological analysis.
Soil Sampling Methodology
Sample Distribution
Samples should be collected according to soil type and crop distribution patterns, following a zigzag or serpentine pattern for representative sampling.
Sampling Depth
Typically 0-20cm, adjusted based on cultivated layer thickness.
Soil Sampling Procedure
- Divide the field into homogeneous units based on visual assessment
- Clear surface litter at sampling locations
- Drive auger to 15cm depth to collect samples
- Gather 10-15 samples per unit for comprehensive analysis
- Alternative method: Create 'V' shaped cut with spade and collect soil slices
