NQ core drilling rig
The NQ core drilling rig is a specialized piece of equipment designed for geological exploration and mineral development. Its core function is to efficiently obtain intact underground rock core samples. It uses a rotating drill rod to drive a drill bit to break up the rock and continuously extract core samples for geologists to analyze stratigraphic structure, mineral composition, and resource reserves. In core fields such as geological exploration, mining development, and infrastructure surveying, the accuracy and efficiency of core sampling directly determine project progress and cost control. The YG NQ core drilling rig, designed specifically for medium-to-deep exploration, has become the preferred equipment for exploration teams worldwide due to its stable performance from a fully hydraulic drive and its adaptability to various scenarios. Whether in complex terrains like high mountains and dense forests or harsh environments of extreme cold and heat, this equipment can achieve efficient and accurate core sampling, providing reliable support for geological data analysis and resource assessment.

The core working principle of the YG NQ core drilling rig is to transmit power through a fully hydraulic system to achieve drill rod rotation and feed, while a cooling and lubrication system ensures core extraction quality. The overall process can be divided into three key steps, which can be simply understood as follows:
Step 1: Power Drive. The equipment’s engine drives the hydraulic pump, converting mechanical energy into hydraulic energy. Hydraulic oil is delivered through sealed pipelines to various actuators, such as the rotation mechanism and feed mechanism, providing power for the equipment’s operation. This step is like a “hydraulic engine,” transmitting power through oil, which is smoother and more controllable than traditional mechanical transmission.
Step 2: Precise Core Extraction. The operator sets drilling parameters through a centralized control panel. The hydraulic system drives the top drive rotating head, causing the NQ drill rod to rotate at high speed. Simultaneously, the feed mechanism controls the drill rod to descend slowly. The drill bit contacts and cuts the rock formation to form a core. During this process, the cooling system continuously delivers coolant, both to reduce the drill bit temperature and to carry rock dust out of the borehole, ensuring the integrity of the core.
Step 3: Core Extraction. Once the drill rod reaches the set depth, the hydraulic winch is activated to lift the drill rod containing the rock core to the ground. The rock core is then removed using specialized tools, completing one core sampling operation. Throughout the process, the intelligent control system monitors data such as pressure and rotation speed in real time to ensure stable and safe operation.
Advantages of the YG NQ Core Drilling Rig
Significant Efficiency Improvement: Fully hydraulic drive and stepless speed regulation design increase hard rock drilling speed by 40% compared to traditional equipment, reducing single-hole operation time by 30%, and facilitating earlier project delivery.
Reduced Maintenance Costs: Core components use wear-resistant materials, extending service life by 50%; modular design facilitates component replacement and maintenance, eliminating the need for a professional team for routine maintenance, reducing annual maintenance costs by 35%.
Optimized Personnel Costs: The equipment uses a centralized control panel, integrating all operation buttons and data dashboards, allowing a single person to control the operation, reducing the need for 2-3 operators and saving on labor costs in the long term.
Versatile and Cost-Effective: Compatible with multiple specifications, such as the BQ core drilling rig and HQ core drilling rig, a single unit can cover exploration needs at different depths and hole diameters, avoiding the need for multiple equipment purchases and reducing initial investment costs.
Factory Direct Sales Guarantee: YG directly connects with customers, eliminating intermediate agents and offering more competitive prices; it provides a 2-year warranty and global on-site repair service, with 24-hour response to equipment failures to ensure uninterrupted operation.
