The excavator-modified drilling rig has a drilling diameter of 42-110mm and is suitable for ordinary hardness stone layers. It achieves excellent results on common bluestone and limestone, with a drilling efficiency of 0.5-2 meters per minute. The drill arm track length is either 3 meters or 6 meters, and the drilling depth can reach 20 meters (achieved by changing rods). How can we reduce operating costs and extend service life during use?

The hydraulic assembly of the excavator-modified drilling rig provides the torque for the high-speed hydraulic motor, while the air compressor assembly is responsible for the main drilling operations, supplying the impact force of the impactor and completing slag removal. Due to the high requirements for the air compressor, a high-air-volume compressor may not be mountable on a small excavator and may need to be towed separately. It is recommended to modify an excavator with a low tonnage of 8 tons.

1. Avoiding Impurities: For an excavator-modified hydraulic rock drilling rig that needs to operate in harsh environments or complex conditions, first, use high-quality, compatible parts, grease, and lubricating oil to block the source of harmful impurities. Second, ensure proper mechanical protection at the worksite to guarantee that relevant mechanisms function normally and prevent various impurities from entering the equipment.
2. Appropriate Temperature: During the use of the excavator-modified drilling rig, avoid overloading at low or high temperatures. Ensure the normal operation of the preheating phase so that the equipment reaches the standard operating temperature before proceeding with movement or operation.
3. Corrosion Prevention: Based on local weather conditions and pollution levels at the time, take effective measures to reduce the impact of chemical corrosion on the equipment. The key focus is to prevent rainwater and chemical components in the air from invading the equipment.

II. Appropriate Operating Load: The size and nature of the operating load of the excavator-modified drilling rig have a critical impact on the equipment’s wear process. Stable loads result in less wear, fewer failures, and a lower lifespan compared to dynamic loads. Therefore, first, ensure that the normal operating load does not exceed the maximum load the equipment can handle. Second, strive to maintain uniform load increases and decreases, keeping the equipment under relatively gentle load changes.

III. Proper Use of Lubricating Oil: Due to the precision coordination of the components in the excavator-modified hydraulic rock drilling rig, good lubrication can maintain normal working gaps and appropriate operating temperatures, thereby reducing wear on parts and minimizing equipment failures. Proper and effective lubrication is one of the useful measures to reduce equipment failures. Therefore, first, select the correct lubricating fluid. Second, frequently check the quantity and quality of the lubricating fluid.

IV. Timely Maintenance and Repair: Some faults in the excavator-modified drilling rig may have minimal impact on the equipment, while others can be more severe. Serious mechanical failures are often caused by smaller faults. Therefore, regardless of the scale of mechanical faults, they should be addressed promptly, and appropriate maintenance and repair work should be conducted.

V. Coordination of Technology and Organization:

1. Pay attention to preventing damage, deformation, or rusting of the excavator-modified drilling rig during transportation and storage processes.
2. Adhere to the principles of daily maintenance work for the machinery to keep the equipment in good technical condition.
3. Train operators to correctly use and operate various excavator-modified drilling rigs, reducing and preventing equipment failures caused by human error.
4. Carefully maintain the excavator-modified drilling rig, ensuring that regular and irregular maintenance is carried out correctly and effectively. Keep the equipment clean and tidy, regularly inspect its technical condition, address abnormalities promptly, tighten and adjust loose or misaligned parts immediately, and perform preventive replacement of certain wear-prone components.
