KG520/KG520H Down the Hole Drill Rig - China Suppliers & Factory, Environmentally Friendly and High Efficiency
Product Introduction
The KG520/KG520H down the hole drill rig for open use.
This device is an upgraded and improved device. It is equipped with Yuchai non-road four-cylinder engine to meet emission standards and environmental protection requirements. The use of flanged track frame and four-wheel belt, improve the working pressure, increase the rotary torque and speed, increase the lifting cylinder and chain. The shell is hemmed with thickened profiles to increase strength and rigidity. Convenient loading, unloading and hoisting.
At the same time, we increase the dust collector, can make the operation more environmental.
The core component of the DTH drilling rig is the DTH hammer, which uses compressed air to drive the internal piston to reciprocate at high speed, generating powerful impact. The impact force is transmitted to the rock through the drill bit, causing the rock to break. At the same time, the drill pipe drives the drill bit to rotate, further breaking the rock and discharging the drill cuttings out of the hole. Compressed air not only drives the DTH hammer, but is also used to cool the drill bit and remove cuttings.
Key Components
1. DTH Hammer
Installed at the end of the drill pipe, responsible for generating impact force. Select the appropriate DTH hammer model and specifications according to different geological conditions and drilling needs.
2. Drill Bit
Used in conjunction with DTH hammer to break rocks. Common drill bit types include ball-tooth drill bits and cross-bit drill bits.
3. Drill Pipe
Connects the drilling rig and DTH hammer to transmit rotational force and compressed air. The length and diameter of the drill pipe are selected based on the drilling depth and diameter.
4. Compressor
Provides high-pressure air to drive the DTH hammer and remove drilling chips. The compressor capacity and pressure should meet the needs of the drilling rig.
5. Power System
It is usually powered by a diesel engine or electric motor to drive various functions of the drilling rig.
6. Control System
Used to operate and monitor various parameters of the drilling rig to ensure the safety and efficiency of the drilling process.
Diesel engine portable screw air compressor: kaishan Lgcy-18/17, kaishan Lgcy-19.5/19.

Frequently Asked Questions
Q: What engine is used in the KG520/KG520H drill rig?
The KG520/KG520H drilling rig is equipped with a Yuchai non-road four-cylinder engine, which is designed to meet emission standards and environmental protection requirements.
Q: How does the dust collector benefit the drilling operation?
The integrated dust collector significantly reduces dust emissions during operation, making the drilling process much more environmentally friendly and safer for operators.
Q: What is the working principle of the DTH hammer?
The DTH hammer uses high-pressure compressed air to drive its internal piston to reciprocate at high speed. This action generates a powerful impact force that is transmitted directly to the rock via the drill bit, breaking the rock efficiently.
Q: What are the drilling capacity specs for the KG520/KG520H?
It supports a drilling diameter range of 105-152mm and can reach a maximum drilling depth of 25 meters under suitable geological conditions.
Q: Which air compressors are recommended for this DTH drilling rig?
The recommended portable diesel screw air compressors are the Kaishan Lgcy-18/17 and Kaishan Lgcy-19.5/19 models.
