The modified hydraulic rock drilling machine, known as the excavator converted into a down-the-hole (DTH) drill rig, is a mature mechanical rock excavation equipment. It only requires the hydraulic system of the excavator’s hydraulic hammer as the power source. The installation process is simple and involves connecting the inlet and outlet ports of the hydraulic hammer to the drill rig. This allows the hydraulic oil from the excavator to provide pressure to the drill rig’s boom, feed, and rotation systems, enabling rock drilling and hole drilling operations.
The diesel-powered screw air compressor used in conjunction with the drill rig does not require the hydraulic oil from the excavator. It operates independently and provides ample air pressure and volume for effective impact and debris discharge. If a dust collector needs to be installed, the excavator’s hydraulic power source can be directly used. This allows the excavator to gain rock drilling and dust removal capabilities, enhancing its overall performance and productivity.
The modified rock drilling excavator can operate in various rock formations. It is primarily used for drilling with diameters ranging from Φ90 to Φ300 and rock hardness between f=6-18.
Utilizing the excavator’s own hydraulic power source results in minimal power consumption and high energy utilization efficiency. The modification process is also convenient, allowing for easy installation and removal.
The modified drill rig can automatically adjust parameters such as rotary torque, speed, thrust, and impact frequency, optimizing the drilling operation under various conditions while maintaining the total power output. This maximizes the efficiency of the machine.
Operators can work from the excavator’s cabin, controlling the drill rig’s operations directly through an operation control box, ensuring safety and comfort during operation.
Optional dust removal system can be equipped, consisting of a primary settling tank and a secondary electromagnetic pulse dust removal box. This significantly improves the working environment on-site, protects the health of the workers, and effectively reduces dust pollution.
By mounting the down-the-hole drill on the excavator and utilizing its hydraulic system, the excavator is transformed into a crawler-mounted drill rig, expanding its functionality and versatility.
The power source for the down-the-hole impactor is a diesel-powered screw air compressor, which is installed on the excavator. This eliminates the need for separate towing of a mobile air compressor and solves the difficulties associated with moving and climbing slopes.
