Feature

1. Fully automated drill rod handling system significantly reduces manual labor intensity
Equipped with an automated drill rod handling unit, the system enables one-touch execution of rod loading, coupling, unloading, and storage. Operators no longer need to manually handle the rods; this not only boosts continuous drilling efficiency but also eliminates safety hazards such as collisions or hand-pinching injuries associated with manual operation. The system offers superior stability during prolonged, high-intensity drilling, making it ideal for large-scale, continuous deep-hole projects.
2. Lightweight aluminum alloy feed beam ensures high drilling efficiency and exceptional operational stability
The main feed beam is manufactured as a single piece from high-strength aluminum alloy, achieving a lightweight design without compromising structural rigidity or resistance to vibration and impact. Compared to traditional heavy steel beams, this design reduces the load on the machine during travel, ensures smoother feed motion, improves drilling straightness, and lowers drilling resistance. It guarantees vertical hole accuracy and resists deformation during frequent, long-term rock drilling, balancing operational efficiency with equipment longevity.
3. Imported core mechanical components offer dust and water resistance, withstanding harsh mining environments
Key hydraulic, transmission, and control components are sourced from top-tier international brands and undergo rigorous factory sealing to ensure excellent resistance against dust, water, and sediment intrusion. Even in challenging site conditions-such as heavy airborne dust, standing water, and flying debris-internal valves, piping, and transmission mechanisms remain free from jamming, corrosion, and failure. This significantly lowers the overall failure rate and greatly enhances reliability for continuous field operations.
4. Built-in single-stage high-efficiency screw air compressor delivers abundant, reliable airflow
The unit integrates a high-power, single-stage, high-efficiency screw air compressor that provides stable pressure, high air volume, and superior generation efficiency, ensuring a continuous and ample air supply for the DTH (Down-The-Hole) impactor. The system operates with minimal vibration and optimized fuel consumption; the cooling system is tailored for specific working conditions to prevent overheating or shutdowns during prolonged full-load operation, ensuring uninterrupted power for deep-hole drilling. Additionally, the integrated layout eliminates the cumbersome steps of transporting and connecting a separate external air compressor.

5. Equipped with an Eaton rotation motor for powerful rotation and outstanding drilling efficiency
The rotation system features a renowned Eaton motor, delivering ample torque and responsive power with smooth, robust rotational force. It resists stalling or jamming when drilling in hard rock, granite, or fractured strata. Rotation speed adapts flexibly to rock hardness, ensuring excellent coordination between impact and rotation for superior penetration, high drilling efficiency, and low failure rates.
6. High-capacity 14-element dust-filtering air cleaner; supports standard 90–115mm hole diameters
Comes standard with a 14-element air filter offering a large filtration area. With superior dust-holding capacity and interception efficiency, it effectively filters the large volumes of rock cuttings and fine dust generated during drilling. This protects the engine and air compressor intake systems, extends the machine's service life, and reduces dust pollution at the work site. It supports standard hole diameters from 90mm to 115mm, perfectly meeting requirements for open-pit blasting and pre-splitting holes with exceptional versatility.
7. Spacious, open-access maintenance design for quick and easy replacement of wear parts
The machine's structure was designed with maintenance in mind, featuring large, open access points on the side and top. High-wear components-such as internal hydraulic lines, motors, filter elements, impactor connections, and seals-are clearly visible and accessible. Maintenance personnel can quickly replace filters and service oil lines, motors, and impactors without extensive disassembly of the housing, significantly reducing downtime and increasing equipment availability.
8. Dual-stage air filtration system for robust performance in high-dust mining environments
In addition to the main dust-filtering air cleaner, two supplementary progressive filtration stages are included, creating a comprehensive, multi-layer protective filtration system. Designed for the extremely harsh operating conditions of quarries and open-pit mines-characterized by excessive dust and flying rock debris-this system employs multi-stage filtration to block impurities from entering the powertrain and pneumatic systems. It minimizes internal wear on cylinders, screw rotors, and impactors, thereby reducing failures caused by intake contaminants at the source, extending the interval between major overhauls, and lowering long-term maintenance and operating costs for the customer.

The YRID 101 High-Efficiency Integrated DTH Drill Rig for Mines combines automated operation, durable core components, robust dust protection, and an easy-to-maintain structure. Balancing operational efficiency, stability, and cost-effectiveness in maintenance, it is widely applicable to various field projects-such as open-pit mine blasting, quarry excavation, road infrastructure, slope stabilization, and photovoltaic pile drilling. It is a preferred choice for overseas contractors and mining enterprises seeking highly reliable drilling equipment.

FAQ

Q1: What is the drilling diameter range for the YRID101 integrated DTH (Down-The-Hole) drill rig, and what types of projects is it suitable for?

A: It features a standard hole diameter range of 90–115mm and comes equipped with a 14-element high-capacity dust-filtering air cleaner, ensuring robust dust removal and cuttings discharge capabilities. It is primarily used for rock drilling operations in hard rock formations-such as open-pit mine blasting holes, quarrying, slope anchoring for road infrastructure, earthworks, and pile foundation drilling for photovoltaic power plants-offering excellent versatility for both mining operations and remote field sites.

Q2: What specific practical benefits does the fully automatic drill rod handling system offer?

A: The machine is equipped with a fully automatic drill rod handling mechanism that executes the entire process-loading, connecting, unloading, and storing rods-with a single-button operation, eliminating the need for manual rod handling. This significantly reduces labor intensity and prevents safety accidents like hand injuries or crushing. Additionally, it enables continuous deep-hole drilling without interruption, markedly boosting overall construction efficiency, making it ideal for projects requiring large volumes of closely spaced blast holes.

Q3: What are the advantages of the aluminum alloy feed beam compared to a steel one? Is there a risk of insufficient rigidity?

A: The main feed beam is manufactured from high-strength aluminum alloy using an integrated molding process, achieving a lightweight design while maintaining the structural strength needed to withstand vibration and impact. This reduces the load during machine travel and ensures smoother feed motion, resulting in better verticality and reduced hole deviation. It resists deformation during long-term, high-frequency drilling and lowers fuel consumption, striking an optimal balance between stability, drilling efficiency, and durability.

Q4: How does the equipment handle dust and water, and can it withstand the harsh, high-dust environments found in mines across Africa and Southeast Asia?

A: Core hydraulic and transmission components are sourced from premium international brands, and the entire machine features comprehensive sealing and dust/water protection. It utilizes a dual-protection system-combining a 14-element main dust-filtering air cleaner with a two-stage progressive air filtration system-to effectively block dust, silt, and debris from entering the engine and air compressor. This ensures stable, continuous operation over long periods in high-dust, muddy, or high-temperature open-pit mining environments with a lower failure rate.

Q5: What brand is the rotation motor, and is the rig prone to getting stuck when drilling in hard rock?

A: The rotation system features an Eaton rotation motor, offering ample torque reserve and smooth power response. Rotation speed can be flexibly adjusted for granite and hard, fractured rock formations. The high degree of matching between impact and rotation effectively minimizes stalling and bit-sticking, ensures strong hard-rock penetration, and maintains stable, reliable operation during prolonged use.
