General Description
The RCJ800C diamond core drilling rig is a powerful tool for hard rock drilling. Full hydraulic drive and advanced power head technology provide strong power and flexible rotation speed. The two-speed feed and transverse translation mechanism ensure the stability and reliability of the operation. The lifting and sliding design of the drilling tower allows the drilling angle to be adjusted freely. Load-sensitive hydraulic system improves operating efficiency and torque output.
Core drilling is a drilling method that extracts cores during the drilling process to research underground geological conditions. The RCJ800C diamond core drilling rig is equipped with hydraulic clamps, leveling legs, and telescopic derricks to achieve rapid positioning and safe drilling operations. The wireless remote control crawler chassis allows the diamond core drilling rig to operate flexibly in complex terrain to ensure operator safety.

The equipment is equipped with a 3-meter-long pipe pole and a sturdy steel crawler chassis, which enhances its maneuverability and transportation convenience in complex terrain. A 92kW 6-cylinder Yuchai engine provides abundant power source for the drilling rig. The rotation speed of up to 1400 rpm ensures the drilling rig's ability to drill quickly in rock formations.
RCJ800C diamond core drilling rig
The performance of geological core drilling rigs depends on many key technologies, and RCJ800C has outstanding performance in these technologies, providing reliable guarantees for various geological exploration work.
key technology
Drill rod design
The drill rod is a fundamental component of the drilling rig. The RCJ800C drill rod is made with optimal strength and rigidity to handle the various loads during the drilling process. Additionally, the design prioritizes both deadweight reduction and ease of transportation, ensuring high operational efficiency while minimizing costs.
Drill Bit Selection
Choosing the right drill bit is critical for successful drilling operations. The RCJ800C is compatible with various geological conditions, including loose soil and bedrock (hardness F6 - 20). By selecting the appropriate drill bit based on specific strata, users can improve drilling speed and achieve higher core sample quality.
Circulation System Optimization
The RCJ800C has an optimized circulation system. It is equipped with the BW160/10 mud pump, a horizontal three-cylinder reciprocating piston pump. Key parameters, such as a 70mm cylinder diameter, 70mm stroke, and 200 strokes per minute, enhance flushing efficiency and rock cuttings removal. This reduces the risk of drill bit jamming and borehole collapse while improving energy efficiency, reducing environmental impact, and enhancing work safety.
Drilling Process Control
Effective drilling process control is crucial for maintaining the integrity and accuracy of core samples. With the RCJ800C, real-time monitoring of drilling parameters, core sampling, and drilling path control enables immediate identification and resolution of issues.
Application
The selection of core samples is a very important task. In addition to directly observing the core, the important content of core sampling is to determine the rock physical properties, organic geochemical characteristics, oil saturation, etc. through the analysis of core samples. RCJ800C diamond core drilling rig is mainly used for metal and non-metallic solid mineral exploration, and can also be used for engineering geological exploration, hydrogeological survey, oil and gas field survey and exploration, and water well drilling.
