Core Drilling Bucket with Roller Bits for Accurate Core Sampling Drilling

It is prohibited to use the bucket to drop and impact rocks, avoid prying objects with the back plate, and do not use slewing force to hit objects.

Use reinforced rock buckets with thickened plates, keep the bucket fixed to the boom arm, use backward dragging instead of vertical hitting, and replace worn teeth timely.

For soil/soft rock, use double-bottom sand-sucking buckets; for cobblestones, use rock-embedded double-bottom buckets or double-layer cylinder drills; for hard rock, use joint construction of cylinder drill and rock-embedded spiral drill bits.

Keep the mud liquid level stable, deal immediately with bubbles or slurry seepage, and park the rig on solid flat ground away from soil-taking slopes during shutdown.

Observe if the main hoist depth gauge matches the drill rod joint position, monitor rotation speed (decreases under high load), and check if drill cuttings match the stratum after lifting.
