1. Introduction: The TQZ-2B portable sampling drill can not only take soil samples and core samples, but also guide holes for grouting. It is a multi-purpose micro engineering drill.

A core drilling rig that can be operated by 2 people! The drilling depth can reach 30 meters! It is powered by a lightweight gasoline engine (or optional electric motor). The split type is light and practical, and is very convenient for relocation. The bracket is stable and reliable, and can be used when wild vehicles cannot enter areas. Use; The drilling rig is simple to operate, easy to learn and understand. It can meet the needs of drilling with alloy and diamond drill bits, twist spiral drilling and pilot hole drilling with non-coring tri-blade alloy drill bits and composite chip non-coring drill bits.

During the drilling process, lifting and feeding are accomplished by relying on the pressurized hand wheel through the sprocket chain, which greatly increases the lifting and pressurizing force of the drilling rig. During the drilling process, the mud pump is used to cool the rotor and drill bit, and carry soil and cuttings back to the surface. As the drilling tool extends underground, the required soil and rock samples continue to enter the core tube. When the soil and rock samples reach the predetermined depth, the drill pipe can be taken out, realizing a single-pass sampling operation. Repeat the above steps until all wells are sampled.

The TQZ-2B lightweight sampling drill is designed and built by domestic professionals through experience accumulation and field inspection for mining survey, oil field survey, and geological research and exploration. It uses imported components and is launched through field inspection and is widely suitable for field operations with inconvenient transportation. Sampling equipment. It is widely used in industrial and civil construction, bridges, railways, highways, hydropower, mining and other industries.
