The JRC200 reverse circulation drilling rig is a new multi-purpose, high-efficiency, environmentally friendly multi-track-type machine that employs advanced foreign gas lift reverse circulation technology. It effectively collects rock dust through a dust collector to prevent environmental pollution and allows for slagging collection via a cyclone separator, ideal for geological prospecting and sampling analysis. This rig is the preferred equipment for geological exploration drilling, well drilling, monitoring wells, ground source heat pump air-conditioning, and other deep hole applications. All systems, including lifting, guide compensation, drill pipe handling, rotation, feed, legs, winch, and walking, are hydraulic, significantly reducing labor intensity while improving construction efficiency and quality.

Functions and Features

Main Components

Reverse Circulation with DTH Technology Combines reverse circulation and DTH methods, where an air compressor supplies pressurized air for impact drilling and efficient dust collection.
Positive Circulation Compatibility Also supports positive circulation drilling using standard tools for versatile applications.
Self-Walking Mobility System Features a self-propelled walking system with four hydraulic legs for easy relocation; can be loaded directly onto a truck without additional hiking.

Hydraulic System Integration Diesel engine mounted hydraulic system encompasses walking, rotation, feed, lifting, legs, compensation, and rod change, ensuring seamless operation and reduced manual effort.
Dual Tube Drilling Mechanism Utilizes a reverse circulation hammer with double tubes; pressurized air enters between the tubes, and cuttings are expelled through the inner tube for contamination-free samples.
Adjustable Drilling Parameters Axis pressure, feed speed, and rotary speed are fully adjustable to optimize performance based on site conditions.
Stability and Balance Features Four hydraulic legs maintain rig balance during operation, enhancing safety and precision.

Features Introduction

Product Description

The JRC200 Hydraulic DTH Reverse Circulation Drilling Rig is a high-efficiency and environmentally friendly drilling solution designed for geological exploration and sampling applications. It supports drilling diameters from Φ105 to Φ350 mm with a maximum drilling depth of 200 m, and is suitable for geological prospecting, well drilling, monitoring wells, ground source heat pump installation, and civil engineering projects.

Integrating advanced reverse circulation and DTH drilling technology, the JRC200 enables clean and accurate sample collection through a cyclone separator and dust collector, effectively reducing environmental pollution. All major functions—including walking, rotation, feeding, lifting, rod handling, and leveling—are fully hydraulically driven, significantly reducing labor intensity while improving drilling efficiency, stability, and overall operational quality across diverse field conditions.

Reverse Circulation DTH Drilling System

The combined reverse circulation and DTH technology ensures efficient impact drilling while delivering clean, contamination-free cuttings through the inner tube for accurate sampling.

Full Hydraulic Integrated Operation

All drilling, handling, and mobility functions are hydraulically powered, providing smooth operation, precise control, and reduced manual workload on site.

Mobile & Stable Field Design

The self-walking system with four hydraulic legs allows quick relocation and stable positioning, ensuring safe and efficient operation in varied terrain and working environments.
