Sand-collecting drill bits, also known as rotary drilling bits, play a vital role in geological exploration and construction engineering.#drill machine set#
The main functions of sand-collecting drill bits are as follows:
Formwork Breaking and Drilling:
Sand-collecting drill bits use cutting tools such as bucket teeth and cutting teeth to break up formations and achieve drilling operations.
These cutting tools can be combined according to different formation hardness; for example, soil teeth are used for softer formations, while cutting teeth are used for harder formations.
In the design of double-bottom sand-collecting drill bits, the cutting tools can flexibly use bucket teeth, cutting teeth, or combinations of teeth to adapt to the needs of different formations.
Drill Cuttings Collection and Discharge:#drill machine set#
During drilling, sand-collecting drill bits can collect drill cuttings from the bottom of the hole into the drill barrel.
When the drill bit is raised, the drill rig pressure plate opens the pressure rod mechanism at the top of the drill bit, causing the bottom plate that was held there to open and dump the extracted cuttings.
The double-bottom plate design ensures that drill cuttings are effectively stored inside the barrel, improving drilling efficiency.
Improved Drilling Efficiency:
Optimized design of the sand-dredging drill bucket, such as the double-support plate unlocking design, the use of internationally standardized steel, and the design of the bucket top connection protection block, are all aimed at improving drilling efficiency and stability.
The tooth arrangement method, developed through thorough design calculations and product testing, can optimize the cutting surface while ensuring the pile dimensions, thereby improving cutting efficiency and reducing tooth wear.
Adaptability to Different Formations:
Sand-dredging drill buckets are available in various types, such as soil sand-dredging buckets and rock-embedded sand-dredging buckets (cutting tooth sand-dredging buckets), making them suitable for different formation conditions, such as silt layers, sand...#drill machine set#
