Description

Technical Field

[0001] This utility model relates to the field of diamond drill bit technology, specifically a mining diamond drill bit. Background Technology

[0002] The rock-breaking action of diamond drill bits is accomplished by diamond particles. In hard formations, a single diamond particle, under drilling pressure, puts the rock under extremely high stress (approximately 4200-5700 MPa, some sources suggest up to 6300 MPa), causing a lithological transformation in the rock, changing it from brittle to ductile. The single diamond particle penetrates the formation and cuts through the rock under torque. The cutting depth is basically equal to the penetration depth of the diamond particle. This process is like "plowing the ground," hence the term "plowing cutting action of diamond drill bits."

[0003] Currently, most existing mining diamond drill bits have a fixed connection between the mounting rod and the drill bit. When the drill bit is severely worn, the mounting rod needs to be replaced along with it, which increases the operating cost. Furthermore, the method of pumping water from the outside to the inside of the drill bit results in poor heat dissipation, which significantly reduces the lifespan of the drill bit. Therefore, there is an urgent need for a mining diamond drill bit to improve these problems. Utility Model Content

[0032] Reference Figure 2 and Figure 3 The threaded cylinder 8 is engaged inside the through hole 4 and the mounting hole 11. The threaded rod 9 is adapted to the threaded cylinder 8. The positioning block 10 is engaged inside the positioning hole 13. The limiting plate 12 is fixedly connected to the bottom of the positioning block 10. In this embodiment, the threaded cylinder 8 serves to engage the positioning block 10, the threaded rod 9 serves to fix the threaded cylinder 8, and the mounting hole 11 serves to engage the threaded cylinder 8.

[0033] Reference Figure 4 and Figure 5 The installation rod 1 is equipped with a cooling device 14. The cooling device 14 includes a connecting groove 15 and a diversion hole 16. The connecting groove 15 is equipped with a rotary joint 17. The diversion hole 16 is equipped with a one-way valve 18 and a steel pipe 19. One end of the steel pipe 19 is equipped with a nozzle 20. In this embodiment, the connecting groove 15 serves to fix the rotary joint 17, the diversion hole 16 serves to transport water, and the rotary joint 17 serves to facilitate water filling.

[0034] Reference Figure 4 and Figure 5Both the connecting groove 15 and the diversion hole 16 are opened inside the mounting rod 1. The one-way valve 18 is fixedly connected to the inside of the diversion hole 16. The rotary joint 17 is fixedly connected to the inside of the connecting groove 15. The steel pipe 19 is snapped into the inside of the limiting plate 12. In this embodiment, the one-way valve 18 plays the role of preventing water backflow, and the steel pipe 19 plays the role of transporting water.

[0035] Reference Figure 5 A drill bit 21 is provided on the outside of the nozzle 20. The nozzle 20 is fixedly connected to the inside of the drill bit 21. The end of the steel pipe 19 away from the diversion hole 16 is clamped to the inside of the drill bit 21. In this embodiment, the nozzle 20 plays the role of spraying water, and the drill bit 21 plays the role of mining.

[0036] The implementation principle of this embodiment is as follows:

[0037] When the mounting rod 1 is connected to the inside of the equipment, the top of the baffle 7 will fit against the equipment to prevent the baffle 7 from sliding accidentally during the operation of the drill bit 21.

[0038] When drill bit 21 is severely worn and needs to be replaced, first remove mounting rod 1 from the inside of the equipment. During the process of removing mounting rod 1 from the equipment, baffle 7 will gradually move away from the equipment until mounting rod 1 is pulled out of the equipment. Baffle 7 will then be unrestricted. At this time, baffle 7 can be pushed upward. During the process of pushing baffle 7 upward, slider 5 will slide inside slide groove 3, and the output shaft of spring rod 6 will be gradually compressed. When the output shaft of spring rod 6 is fully compressed, threaded cylinder 8 and threaded rod 9 are exposed. At this time, a tool can be used to rotate threaded rod 9 or threaded cylinder 8 to separate threaded rod 9 from threaded cylinder 8. After threaded rod 9 and threaded cylinder 8 are separated, threaded cylinder 8 is pulled out from the inside of through hole 4 and mounting hole 11. Then, force is applied by limiting plate 12 to pull positioning block 10 out from the inside of positioning hole 13. After positioning block 10 is pulled out from the inside of positioning hole 13, mounting rod 1 will be partially separated from drill bit 21. Then, a new drill bit 21 is taken out and installed at one end of mounting rod 1.

[0039] When assembling the mounting rod 1 and the drill bit 21, the positioning block 10 needs to be inserted into the positioning hole 13 first. After the positioning block 10 is fully inserted into the positioning hole 13, the through hole 4 and the mounting hole 11 will be concentric. At this time, the threaded cylinder 8 is inserted into the through hole 4 and the mounting hole 11, and the threaded rod 9 is installed into the threaded cylinder 8. The threaded rod 9 is then tightened with a tool. The replacement of the drill bit 21 is now complete. Then, the baffle 7 is released, and the output shaft of the spring rod 6 will quickly extend outward and push the baffle 7 downward. When the output shaft of the spring rod 6 is fully extended, the baffle 7 will hide the threaded rod 9 and the threaded cylinder 8 to prevent damage during operation.

[0040] During the mining process, a pipe is connected to the inside of the rotary joint 17. During the operation of the drill bit 21, water is added to the inside of the diversion hole 16 through the rotary joint 17. When the water enters the inside of the diversion hole 16, it first passes through the one-way valve 18 (the one-way valve 18 is installed inside the diversion hole 16 to effectively prevent water backflow). After passing through the diversion hole 16, the water enters the inside of the steel pipe 19. After passing through the steel pipe 19, it is sprayed out by the nozzle 20, which is located inside the drill bit 21. The water is first stored in the internal space of the drill bit 21 until the internal space of the drill bit 21 is filled with water. However, as the water pressure continues to increase, the water will seep out from the connection gap between the drill bit 21 and the mineral, thereby dissipating heat from the drill bit 21 and ensuring that its service life is within the normal range.

[0041] Compared with the prior art, the present invention has the following advantages:

[0042] The sliding groove 3 and the slider 5 work together to facilitate the sliding of the baffle 7. The addition of the spring rod 6 facilitates the resetting of the baffle 7. The baffle 7 also protects the threaded rod 9 and the threaded cylinder 8. The through hole 4 and the mounting hole 11 allow for the mounting of the threaded cylinder 8. The cooperation between the threaded cylinder 8 and the threaded rod 9 fixes the positioning block 10. The cooperation between the positioning block 10 and the positioning hole 13 facilitates the fixing of the drill bit 21. By using the above structure, the mounting rod 1 and the drill bit 21 can be separated and can be replaced individually. The replacement of drill bit 21 reduces operating costs. A rotary joint 17 is installed inside the connecting groove 15 to facilitate water injection. A one-way valve 18 is added inside the diversion hole 16 to prevent water backflow. The diversion hole 16, in conjunction with the steel pipe 19, transports water. A nozzle 20 is placed inside the drill bit 21 to spray water. Through the above structure, water is sprayed from the inside out. After the water fills the internal space of the drill bit 21, it seeps out to improve the cooling effect and thus ensure the service life of the drill bit 21.

[0043] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
