Core Drilling Rig For Soil Sampling

The system combines an axial piston pump with an oblique axis piston motor, featuring a two-stage mechanical gear speed change and a stepless speed regulation system. This allows intelligent matching of speed and torque based on rock hardness, with a maximum torque of up to 1400 N·m. This ensures stable drilling efficiency in hard rock formations while reducing energy consumption by 15% compared to traditional rigs.
The load-sensitive hydraulic system continuously monitors drilling resistance and automatically adjusts pump volume and pressure. This minimizes idle losses, improves operational efficiency by 30%, reduces drill wear, and extends equipment lifespan.

Multi-Angle Drilling Capability: The mast can be steplessly adjusted between 0° and 90° via a cylinder, supporting horizontal, inclined, and vertical drilling. This enables the rig to meet specific construction requirements, such as tunnel inverts and slope anchoring.

Quick Positioning System: Standard hydraulic leveling legs and telescoping masts, combined with hydraulic wooden horse grippers, allow for fast site leveling and drill calibration within 3 minutes. The system ensures leveling accuracy of ≤0.5° on complex terrains.

Wireless Remote Control Crawler: Equipped with a remote control module, the rig supports wireless operation of the crawler within a 100-meter range. This feature is especially useful in high-risk environments, such as steep slopes and wetlands, allowing operators to monitor and control the rig from a safe distance to minimize accident risks.

Dual-Speed Feed Mechanism: The power head is equipped with a cylinder chain-type dual-speed feed system (fast/slow mode). Fast mode boosts drilling efficiency, while slow mode ensures a core recovery rate of up to 95% in soft or fractured formations. The rig also includes a lateral translation device (±150mm stroke), facilitating precise adjustments in drilling position and preventing redundant drilling.

Modular Design: The rig utilizes a lightweight steel structure, with key components like the power head and mast designed for quick disassembly and assembly. This reduces transportation size by 40%, making it more suitable for hoisting and transport in narrow spaces such as mountains and plateaus.
