YG hydraulic rock drill and splitter is an excavator attachment integrating drilling and splitting functions. It consists of key components including a feed beam, hydraulic rock drill, splitting head, wireless remote control system, and booster cylinder. It adopts imported wedge material together with Swedish drilling technology, and the patented drill frame structure guarantees precise positioning. The Italian hydraulic booster system delivers lightweight and stable power output. Synchronous pressurization of two-stage splitting cylinders generates double rock splitting force. The machine weight is cleverly concentrated on the rear side of the excavator head and stick. It keeps balance even when mounted on a 20-ton small excavator working at high reach. The whole unit supports wireless remote control and can be operated by a single person. Drilling speed reaches nearly one meter per minute, and the splitting crack can be as wide as 5.5 cm.
How Does a Hydraulic Rock Drill and Splitter Work?
The working logic of a hydraulic rock drill and splitter can be summarized as “drill first, then split”. The detailed steps are listed below:
Drilling Stage: The excavator’s hydraulic circuit drives the hydraulic rock drill to drill precise holes of 115–130mm in diameter and up to 1900mm deep on rock surfaces. Drilling speed reaches 800–1000 mm/min.
Switch to Splitting: Once drilling is finished, the equipment automatically rotates the splitting head and inserts it accurately into the pre-drilled hole.
Apply High Pressure: The hydraulic system provides high pressure. Two-stage splitting cylinders apply pressure synchronously, and the wedge assembly creates a double-boosting effect to release massive splitting force.
Rock Fracturing: The rock cracks statically along the preset direction. The crack width can reach 5.5 cm with long fractures, ensuring the rock breaks completely from the base.
Full Process Control: The whole operation proceeds under static hydraulic conditions with high safety. One operator can finish all procedures via wireless remote control.
Comparison: Hydraulic Rock Drill and Splitter Vs Traditional Blasting
Compared with traditional explosive blasting, the drilling and splitting machine holds overwhelming advantages in multiple aspects:
Safety: Blasting involves risks such as misfires, flying rocks, and vibration, requiring complicated safety protection. The drill & splitter works under static hydraulic pressure without safety hazards. No isolation or warning zones are needed.
Environmental Protection: Blasting causes severe vibration, loud noise, and massive dust. This unit generates no vibration, no impact, low noise, and little dust. It can operate without disturbance in densely populated areas or near precision equipment.
Cost Efficiency: Blasting requires high expenses, including approval procedures, explosive transportation, charging, and evacuation. The drill-splitter completes splitting within seconds for continuous operation. It features low running and maintenance costs, with extra security expenses eliminated.
Precision: Blasting cannot easily control fracture direction and block size. hydraulic rock drill and splitter predefines splitting direction, shape, and dimension precisely, reducing overbreak and underbreak.
Efficiency Comparison: Hydraulic rock drill and splitter delivers 4 times higher productivity than conventional hydraulic breakers with larger output volume, making hard rock mining much more efficient.
Advantages of YG Excavator Rock Drill and Splitter
Equipped with multiple proprietary technologies, the YG hydraulic rock drill and splitter stands out among similar products. Its key strengths are shown below:
Premium Power System: Adopts an Italian hydraulic booster system with a lightweight design for stable and efficient performance. Synchronous pressurization of two-stage splitting cylinders achieves double-boosting capacity to handle ultra-hard rock easily.
Robust Material & Precise Structure: Imported wedge material combined with Swedish rock drilling technology. The patented drill frame features a simple, stable structure for accurate positioning, long service life, and low failure rate.
Excellent Operating Experience: Adopting new materials and technologies, the whole unit supports wireless remote control. A single operator can complete drilling and splitting work effortlessly to cut labor costs.
Balanced Gravity Design: All equipment weight concentrates on the rear excavator head and stick. It prevents forward weight shift and loss of balance when the boom is fully extended or lifted. As a result, it can be matched with excavators starting from 20 tons with great compatibility.
High-Efficiency Dust Removal System: Fitted with China’s advanced screw air compressor for high-pressure slag blowing and dust suppression. Low noise, compact size, and energy-saving guarantee dust-free construction for all kinds of rock fragments and dust.
Multi-Angle Operation Capacity: When the excavator boom stretches or lifts high, the excavator rock drill and splitter can drill vertically or upside down accurately. It easily handles harsh working conditions such as steep mountain slopes and sites without free faces.
Application Scenarios of Rock Drilling and Splitting Machine
The rock drilling and splitting machine covers an extremely wide range of working fields. Typical applications are listed as follows:
Mining: Quarrying of dimension stones including granite, marble and limestone; hard rock breaking for metallic and non-metallic mines with controllable block size and high yield.
Tunneling: Excavation of urban underground tunnels, trimming of underbreak and tunnel contour finishing. Low dust and low noise make it ideal for regions with strict environmental standards.
Municipal Construction: Foundation pit excavation, pipeline trench digging, road & bridge foundation works, reinforced concrete demolition. It works silently in residential blocks and commercial zones.
Metro & Underground Works: Can be lowered underground by crane with outstanding flexibility, suitable for hard rock treatment inside metro platforms and tunnels with limited space.
Other Fields: National defense projects, water conservancy works, slope stabilization, replacement for static rock blasting. It fits all projects requiring hard rock breaking where blasting is restricted.
FAQ About Hydraulic Rock Drill and Splitter
Below are frequently asked questions from users with concise answers: Q: What rock hardness is a hydraulic rock drill and splitter suitable for? A: It works for all types of hard rock, including granite, basalt, marble, and limestone. The two-stage boosting system enables efficient splitting even on ultra-hard rock.
Q: Is maintenance easy?
A: The machine features a simple structure and quick replacement of wear parts. Daily maintenance only requires routine hydraulic oil inspection and slag cleaning. It has a long service life and low maintenance costs.
Q: What requirements are there for matched excavators?
A: YG-130 can be fitted on excavators starting from 20 tons with strong adaptability. No complicated modification on excavators is required. Small excavators can achieve powerful performance.
Q: How to guarantee complete rock breakage from the root?
A: It has a long splitting stroke inside the holes and a maximum crack width of up to 5.5 cm. Together with synchronized pressure from two-stage cylinders, cracks extend fully to ensure rocks break cleanly from the base with neat output.
Q: Which components are most vulnerable during construction? How to extend service life?
A: The main wearable parts are wedges of the splitting gun (central wedge and side wear plates), as well as drill bits and drill rods for the rock drill.
Wedge Maintenance: Special ultra-high-pressure wear-resistant grease must be applied every time before inserting the splitting head into holes. Dry friction is strictly forbidden. Dry operation will scratch or even break wedges within a few splits.
Anti-Jamming for Drill Bits: Always monitor airflow/water flow for slag discharge. Prevent drill jamming when working in fractured rock zones.
