Why is your drilling tool stuck?

(1) Dense and solid geology: Dense and solid geology is an important factor for jamming, such as hard plastic soil, dense sand layer, gravel layer, pebble layer and solid rock layer, etc. When the bottom plate of double-bottom or single-bottom drill bucket is opened in the hole, the bottom plate or side teeth are stuck in the dense and solid hole wall due to the offset of the bottom plate during lifting.

(2) Vibration: When drilling into the pebble layer and strongly weathered rock geology with strong vibration, the bottom plate locking mechanism is easily vibrated open and the bottom plate opens during lifting leading to stuck drilling.

(3) Spring metal fatigue: The spring of the drilling bucket drive opening device is fatigued by long-term use, causing the hook to be weak and the locking mechanism to be unstable, and the bottom plate to open, resulting in a stuck drill.

(4) Wear and tear of the drilling tool: The bottom of the drill body is most easily worn out. When the bottom of the drill body is worn thin or worn out, the bottom plate of the drill bucket is weighted at the bottom of the hole, the hook is not weighted and separated from the hanging ring, the hook is free, and when drilling into vibrating or blocky geology such as gravel, pebbles, and strongly weathered rocks, when the particles of the same size enter the hook and block the hanging ring, the bottom plate opens in the process of lifting the drill or lifting the drill, which may cause jamming. The auger may get stuck if the bottom plate is opened during the start of the augering process or during the lifting process.

(5) Deviated hole: If the hole is sharply deviated, after the bucket is lifted to the position of the sharply deviated hole, the drive opening device at the top of the bucket will touch the wall of the sharply deviated hole and cause the bottom plate to open, resulting in a stuck drill.

(6) Smashing rod: The smashing rod falls on the spring pallet and the huge impact vibrates the bottom plate of the bucket, causing a jam.
