NL 50 Core Drilling Rig Application Scope
1. Geological survey work in a highly difficult area that is small and light and convenient for high altitudes
2. Adopting an automatic hydraulic feed mechanism to increase drilling efficiency and reduce labor intensity of workers.
3, Using 8 HP high-efficiency diesel engine as a power for you to export a steady stream of strong power.
3, Application of positive and negative four-speed operation to facilitate a variety of terrain exploration drilling
4. The four-axis bearing positioning of the vertical shaft box ensures that the gyrator is rigid enough to deal with complex geological conditions such as gravel layer and pebble layer.
5. The machine adopts the national patented technology of the taper clutch, which has the outstanding characteristics of large transmission torque, convenient operation and maintenance-free.
Soil sampling method are as follows:
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
