NL50 Engineering Drilling Rig Features
1. Small and light, convenient for high altitude geological operations;
2. The hydraulic automatic feeding mechanism is adopted to improve the drilling efficiency and reduce the labor intensity of workers.
3. The vertical shaft box 4 sets ensure that the gyrator has sufficient rigidity to deal with complicated terrain conditions such as gravel layer and pebble layer;
4. It adopts national patent taper clutch, which has large transmission torque, convenient operation and maintenance-free.
Principle of core drilling
The principle of core drilling machine is basically the same, and the main components are drilling machine, drill pipe, drill bit, etc. The drill provides power to drive the drill pipe and drill bit to drill and obtain deep core samples
soil sampling method
1. Distribution: samples shall be taken according to the soil type and the distribution of crop varieties, and according to the different soil fertility. The sampling points are distributed in zigzag or snake shape, which should be as uniform and random as possible.
2. Determine the sampling position and depth: the sampling position and depth shall be determined according to the thickness of the cultivated layer. Generally, the sampling depth is 0-20cm
Soil Sampling Procedure
Divide the field into different homogeneous units based on the visual observation and farmer's experience.
Remove the surface litter at the sampling spot.
Drive the auger to a plough depth of 15 cm and draw the soil sample.
Collect at least 10 to 15 samples from each sampling unit and place in a bucket or tray.
If auger is not available, make a 'V' shaped cut to a depth of 15 cm in the sampling spot using spade.
Remove thick slices of soil from top to bottom of exposed face of the 'V' shaped cut and place in a clean container.
