The pulse of the earth is hidden within the rock layers. Each section of the rock core is like a historical record written by the earth. And how to accurately and completely read this history book depends on the soul of a drilling machine - whether it was designed specifically for extracting cores. The LANDSONG L-6 fully hydraulic rock core drilling machine is precisely such a professional equipment dedicated to rock core drilling. With a calm demeanor, it helps you uncover the true face of the underground world.
Compact in shape, with steady power
The L-6 complete machine is 4.3 meters long, 2.3 meters wide and 2.3 meters high, weighing 6.6 tons. It has a compact structure yet maintains stability. It is equipped with a Yuchai 92-kilowatt engine, which provides stable and reliable power output. Combined with the 24V electrical system, it can adapt to complex working conditions in the field. The hydraulic system adopts a three-pump independent configuration - the main pump, auxiliary pump and auxiliary pump work together, with a reasonable distribution of flow and pressure, and quick response in actions. The hydraulic oil is cooled by air, ensuring that the system temperature is controllable for long-term continuous operation, and the stability is better.
Deep drilling and coring, combining hardness and flexibility
As a fully hydraulic core drilling machine, the core mission of L-6 is to obtain high-quality core samples. It is compatible with four types of drill pipes: B, N, H, and P. Among them, the B specification can reach a drilling depth of 800 meters, the N specification 600 meters, the H specification 400 meters, and the P specification 100 meters. This covers a wide range of needs from shallow exploration to core extraction at medium and deep depths.
The rotating power head adopts a plunger motor structure and has an automatic speed control function. Its maximum torque can reach 1800 NM and the maximum rotational speed is 1200 rpm. When dealing with hard rock layers, it can maintain a stable rotational cutting force, ensuring both drilling efficiency and the integrity of the core samples - this is the fundamental difference between core drilling rigs and water well drilling rigs: what we aim for is the authenticity and integrity of every meter of the core sample, rather than just the drilling rate.
Strong feed, flexible angles
The "strength" of the drilling rig determines the ease of the pulling operation. The L-6 has an input force of 70 kilonewtons and an uplift force of up to 111 KN. This data stands out among similar models, ensuring smooth pulling of the drill tools and reducing the risk of stuck drill. The drilling angle can be freely adjusted between 45 degrees and 90 degrees. Whether it is a vertical deep hole or an inclined exploration hole, it can handle them with ease. It is compatible with 1.5-meter or 2-meter drill pipes, making the construction organization more flexible.
Mud circulation, process durability
Core drilling cannot be carried out without an efficient and reliable fluid circulation system. The L-6 is equipped with a three-cylinder piston high-pressure mud pump, with a maximum flow rate of 160 liters per minute and a maximum pressure of 8 megapascals. It provides stable and powerful mud transportation at the bottom of the hole, effectively carrying rock debris, cooling the drill bit, and ensuring the stability of the hole wall. The entire machine adopts an electrophoretic and KTL powder spraying coating process, with outstanding anti-corrosion and rust resistance, and is not affected by outdoor weather erosion. The standardized and modular assembly mode makes daily maintenance and component replacement more convenient.
Integrated advantages, clear at a glance
In summary, the L-6 fully hydraulic core drilling rig of the LAND SONG series boasts the following core advantages:
· Professional core extraction capability: With a drilling depth of 800 meters for the B specification, it is specifically designed to obtain genuine rock cores, far surpassing the capabilities of water well drilling rigs.
· The hydraulic system is highly sophisticated: three pumps are independently controlled, the energy distribution is reasonable, the action response is swift, and it is suitable for long-term continuous operation.
· Powerful motor: 1800 Newton-meters of torque and 1200 rpm of rotational speed, ensuring stable and reliable drilling in hard rock.
· Outstanding lifting capacity: 111 kilonewtons of lifting force. The lifting operation is carried out with great composure and strength, significantly reducing the risk of stuck drill pipes.
· Wide adjustable range: 45 to 90 degrees with continuous adjustment, suitable for various drilling inclination requirements.
· Robust and durable: Electrostatic painting + KTL spraying process, modular assembly, easy maintenance.
LANDSONG L-6 does not compromise on quality for the sake of speed, nor does it abandon depth to cater to superficiality. With its precise and composed full-hydraulic operation, it accompanies every geologist, listening to the sounds deep within the earth. Choosing L-6 means choosing a sense of reverence for rock cores and honesty towards data. Let every drilling session become a deep dialogue with the Earth.
