Deep hole sampling device

Deep Hole Sampling Device   KQ-73S Deep Hole Rapid Sampling Device

The deep hole sampling device is made of stainless steel, featuring an exquisite appearance and convenient installation and transportation. It is equipped with extraction ports, feeding ports, discharge doors, etc., and the main body of the device has excellent sealing and practicality.

The deep hole sampling device is suitable for efficiency inspection of boreholes in coal mines. Based on the "taper expansion" hole-sealing principle and a three-way device, the deep hole fixed-point sampling device controllably collects gas-containing coal ejected during the construction of cross-layer boreholes in high-gas and coal-and-gas outburst mines into a sealed container. This avoids injuries and gas over-limit accidents caused by gas blowouts. The borehole sampling device also reduces construction dust and improves occupational hygiene levels, making it one of the auxiliary equipment for modern production mine drilling operations.

Technical Parameters of the Deep Hole Sampling Device

Drill rod: diameter 73mm, torque ≥10000N/m;
