The nine core upgrades comprehensively address construction pain points and enhance equipment performance. However, the product price remains affordable and reasonable, truly achieving "comprehensive performance evolution without increased investment burden".
Currently, the upgraded version of the LANDSONG JH7 fully hydraulic core drilling rig has launched a limited-time discount campaign.
Drilling rig operators have almost all encountered various problems on construction sites: during high-altitude operations, engine black smoke frequently occurs and power is insufficient; when drilling in clayey soil layers, problems such as clogged drill bits and blocked holes often arise, causing the drilling progress to stagnate; the disassembly of drill rods relies on manual operations with sledgehammers and pipe wrenches, which is time-consuming, labor-intensive, and poses a high risk of equipment overheating and malfunction during continuous operation in summer, making the construction completely unreliable.
Through multi-site on-site investigations, we deeply collected various pain points in the first-line construction. In fact, to overcome these construction difficulties, there is no need to spend a large amount of money to customize an exclusive drilling rig. The upgraded version of the LANDSONG JH7 fully hydraulic core drilling rig offers an extremely high cost-effectiveness solution to address all kinds of construction problems, providing high-quality solutions for field exploration and construction!
1. Targeted solutions to address the five major core problems in construction
（1）. Cures low engine power and black smoke emission problems in high-altitude areas | Exclusive high-altitude mode
In high-altitude and low-pressure environments, the engines of ordinary drilling rigs are prone to insufficient air intake and incomplete combustion, frequently causing problems such as black smoke emission, vehicle stalling, and power loss, which directly reduces the overall construction efficiency.The upgraded version of the LANDSONG JH7 core drilling rig is specially equipped with an altitude operation mode. It relies on a high-pressure filtration system and dedicated valve groups to optimize the fuel combustion logic, enabling the engine to fully combust in high-altitude conditions and continuously output stable power. This completely eliminates black smoke and vehicle stalling issues, making outdoor construction in high-altitude areas more stable and efficient.
（2）. Solving the problem of stuck drill and blocked hole in clayey strata | Adding an external flushing interface
When dealing with muddy and highly viscous complex rock formations, even if the flushing flow rate of conventional drilling rigs is increased, the problems of clogged drill and blocked holes still cannot be avoided. The troubleshooting process is time-consuming and labor-intensive, seriously delaying the construction progress.This upgrade independently installs an external flushing interface at the position of the equipment's mud pump. When encountering viscous and complex formations, it can quickly connect with auxiliary flushing equipment to efficiently solve the problems of blocked holes and clogged drill, significantly improving the adaptability of complex formations in construction, and ensuring the reliability of various drilling operations in such formations.
（3）. Improve the difficulty in removing the drill pipe | High-torque function for removing the drill pipe
Under the high-speed and low-torque operation conditions of conventional drilling rigs, the disassembly of drill pipes can only be accomplished by using pipe wrenches in conjunction with manual brute force. This method is not only slow and inefficient but also greatly consumes manpower and physical strength.The upgraded JH7 model adds a high-torque drill pipe disassembly function. During the operation of disassembling the power head of the equipment, it can output an extremely large torque, enabling rapid disassembly and assembly of drill pipes. It completely eliminates the need for manual brute force operations, significantly reduces the duration of auxiliary operations, and directly improves the construction efficiency.
（4）. Optimize the problem of high operational threshold and difficulty in getting started | Intelligent motor automatic speed regulation
Traditional drilling rigs rely on manual speed adjustment by operators. The operation is highly dependent on the experience of experienced workers, making it difficult for beginners to quickly master. The cost of manual operation is high and the limitations are significant.The equipment has been upgraded with an automatic speed adjustment system for hydraulic motors. It can automatically match the optimal speed based on the real-time construction load, with sensitive response and simple operation. Whether it is a senior worker or a novice, they can easily and proficiently operate the equipment, significantly reducing the operational threshold of the equipment.
（5）. Overcoming the overheating issue during continuous high-temperature operations | New water-cooling cooling system
Under the high-temperature conditions in summer, if the drilling rig operates continuously for a long time, the body temperature is prone to rise sharply, and the risk of equipment failure increases significantly. The construction stability cannot be guaranteed.The upgraded JH7 model adds a professional water cooling system, which can efficiently control the temperature rise during equipment operation. It effectively avoids problems of overheating shutdown and failures. Even when conducting continuous construction in the hot summer environment, the equipment remains stable in performance and ensures the uninterrupted progress of the construction.
2. Multiple detailed upgrades, comprehensively enhancing the construction experience
In addition to the optimization of the five core pain points, the equipment has completed iterative upgrades in multiple detailed configurations, further strengthening the construction performance:
(1). Upgraded power generation system: Optimized the power supply performance in the field, making the power supply more stable and more adaptable, suitable for complex working conditions without city power supply in the field.
(2). Drag chain mast structure: Strengthened the overall structural strength, making the telescopic operation more stable, and significantly improving the operational stability.
(3). Upgraded main oil cylinder: Faster drilling speed, lower operational energy consumption, and a balance between efficient construction and energy conservation advantages.
(4). Optimized constant pressure feed system: More uniform and stable pressure output during drilling, effectively improving the hole formation accuracy and quality.
3. All the classic hardcore configurations are retained, and the performance remains undiminished.
This comprehensive upgrade does not remove any of the original high-quality features. The core and powerful performance of the equipment is fully retained, ensuring its effectiveness:
（1）. Maximum drilling depth of 1400m, capable of fully meeting the needs of various engineering projects such as medium and deep-hole exploration and well construction
（2）. Equipped with a WEICHAI 140kW engine, with abundant power and lower energy consumption, the equipment has strong operational stability and a long service life
（3）. Utilizing the dual processes of electroplating and KTL powder spraying, the body is resistant to corrosion and wear, and is less likely to be damaged during long-term outdoor operations
（4）. Compact and lightweight design of the body, high adaptability to the site, flexible and convenient for transportation during relocation, and suitable for various narrow construction sites
