Frequently Asked Questions
How to select the right drilling rig bucket according to geological conditions?
For soil or soft rock layers, use a double-bottom sand-sucking bucket. For cobblestone or moderately weathered rock, a rock-embedded double-bottom bucket is preferred. For hard rock, a combination of cylinder drill circular cutting and rock-embedded spiral drills is recommended.
What operations are most harmful to an excavator bucket?
Dropping and impacting rocks with the bucket, prying objects with the back plate, and using slewing force to hit objects are the most harmful operations, often leading to deformation and cracking.
How can I prevent hole collapse during rotary drilling?
Maintain a stable mud liquid level to keep pressure on the hole wall. If bubbles or slurry seepage occur, address them immediately and ensure the rig is parked on solid, flat ground during shutdowns.
What are the risks of overloading handling equipment?
Overloading by just 10% can reduce the fatigue life of the steel structure by 50%. Additionally, oblique pulling can create lateral forces twice the vertical load, causing track deformation.
How do I extend the life of mining handling equipment?
Clean the hydraulic valve groups daily to prevent dust jamming, use wear-resistant wire ropes, and strictly avoid oblique pulling to prevent structural deformation.
How to prevent cracking in welded parts of buckets?
Regularly inspect the welds on the back plate and hinge shaft. Avoid overloaded prying. If cracks appear, use low-hydrogen electrodes for repair welding and reinforce stress concentration points.
