The double-lobed soil drilling bucket, also commonly known as a two-lobed bucket, open-bodied bucket, or open-face drill, is a type of drilling tool widely used in rotary drilling rigs.#hole machine#
The following is a detailed explanation of the double-lobed soil drilling bucket:
I. Working Principle
The double-lobed soil drilling bucket utilizes a lever mechanism to achieve automatic opening. Its cylinder and bottom plate are integrated; during drilling, the two lobes close, forming a complete bucket for excavating and containing soil.
When the drill is lifted, the bucket is reversed, opening the two lobes and allowing the clay cuttings to fall naturally, thus reducing soil ejection time and damage to the drilling rig.#hole machine#
II. Applicable Formations
Initially, the double-lobed soil drilling bucket was primarily used in clay layers that were difficult to dump. Due to its advantages of fast drilling speed and convenient soil dumping, its application range has now expanded to include dense gravel layers, low-strength sedimentary rocks, and completely weathered and strongly weathered rocks.
III. Advantages and Features
High Drilling Efficiency:
The automatic opening design of the double-lobed soil drilling bucket makes the drilling and soil unloading processes faster, thereby improving drilling efficiency.
Reduced Damage:
The reverse-rotating drill bucket for dumping drill cuttings reduces damage to the drilling rig and extends the equipment's lifespan.
Strong Adaptability:
With continuous technological advancements, the application range of the double-lobed soil drilling bucket is constantly expanding, meeting the needs of more diverse geological formations.
IV. Precautions
When using the double-lobed soil drilling bucket, it is necessary to select the appropriate bucket type and drilling parameters based on the actual geological conditions to ensure drilling effectiveness and construction efficiency.
At the same time, regular inspection and maintenance of the drill bucket are also necessary to ensure it is in good working condition.
In summary, the double-lobed soil drilling bucket is a highly efficient and practical drilling tool that plays an important role in rotary drilling rig construction.#hole machine#
