[0028] See also Figure 1-4The utility model provides a drilling faucet, comprising a core shaft 1 and a copper sleeve 2 rotatably connected to the outside of the core shaft 1, the core shaft 1 having a hollow inner cavity; the core shaft 1 is a rotating part, and the copper sleeve 2 is a non-rotating part; the upper end of the core shaft 1 is a female head 11, and the lower end is a male head 12, the female head 11 is used to connect the main shaft of the drilling rig, and the male head 12 is used to connect the drill rod; the copper sleeve 2 is provided with a water injection hole 21, and the water injection hole 21 is used to connect the water pipe; specifically, the female head 11 and the water injection hole 21 are both provided with internal threads, and the male head 12 is provided with external threads, and the drilling faucet is detachably connected to the main shaft, drill rod and water pipe of the drilling rig through threads; the core shaft 1 is provided with a water through hole 13 that passes through the inner cavity, and the water through hole 13 is connected with the water injection hole 21 in coordination; the water through hole 13 is provided with at least four, and the plurality of water through holes 13 are equidistantly arranged on the core shaft 1. During specific use, the main shaft of the drilling rig drives the core shaft of the drilling faucet to rotate, and then drives the drill rod connected to the core shaft 1 to rotate, and the purpose of geological exploration is achieved by drilling with the drill bit; while the drill bit is drilling, the water pipe connected to the copper sleeve 2 transports the coolant from the pump station to the water injection hole 21, the water hole 13, the inner cavity, the drill rod, and the drill bit in sequence. Since there are multiple water holes 13, the multiple water holes 13 on the core shaft 1 under high-speed operation are respectively connected to the water injection hole 21, and the water injection hole 21 can continuously transport coolant to the water hole 13; and since the core shaft 1 rotates at a high speed, the non-conducting area of the water injection hole 21 briefly overlaps, which can briefly store power for the output coolant, but will not affect the normal delivery of the coolant.
[0029] A first groove 14 is provided on the outside of the core shaft 1, and a second groove 22 is provided on the inside of the copper sleeve 2 to match the first groove 14. A sealing ring 3 is provided between the first groove 14 and the second groove 22. The sealing ring 3 is used to form a seal at the connection between the core shaft 1 and the copper sleeve 2; at least six sealing rings 3 are provided, and multiple sealing rings 3 are evenly distributed on the upper and lower sides of the water hole 13; by providing a sealing ring 3 between the core shaft 1 and the copper sleeve 2, and providing multiple sealing rings 3, the upper and lower sides of the matched water injection hole 21 and the water hole 13 can be sealed to avoid leakage of coolant at the connection between the core shaft 1 and the copper sleeve 2, thereby improving the connection effect between the core shaft 1 and the copper sleeve 2, and thereby improving the application effect of the drilling faucet.
[0030] The outside of the core shaft 1 is also provided with a third groove 15 and a convex portion 16, and a retaining ring 4 is provided in the third groove 15, and the retaining ring 4 abuts against the upper end of the copper sleeve 2, and the convex portion 16 abuts against the lower end of the copper sleeve 2; the retaining ring 4 and the convex portion 16 can cooperate to limit the copper sleeve 2, thereby avoiding the connection between the core shaft 1 and the copper sleeve 2 under high-speed operation from being offset, ensuring the penetration effect of the water injection hole 21 and the water through hole 13, and thereby improving the effect of adding coolant using the drilling faucet.
[0031] The water hole 13 is set to be a stepped type with a narrow outside and a wide inside, and the lower end surface of the water hole 13 is set to be an inclined surface with a high outside and a low inside. Since the coolant enters the water injection hole 21 through the water pipe, and then enters the water hole 13 from the water injection hole 21, and is then sent to the drill rod and the drill bit through the inner cavity, by setting the water hole 13 to be stepped, the stepped water hole 13 with a narrow outside and a wide inside can form a water pressure from the outside to the inside, which is conducive to the coolant quickly entering the water hole 13 from the water injection hole 21, reducing or even avoiding the coolant to be retained in the water injection hole 21, and improving the liquid addition effect; the lower end surface of the inclined surface with a high outside and a low inside of the water hole 13 can use gravity to make the coolant naturally flow downward into the inner cavity, avoiding the coolant to be retained in the water hole 13, and improving the coolant delivery effect. The aperture of the narrow end of the water hole 13 close to the water injection hole 21 is consistent with the aperture of the water injection hole 21, and the water injection hole 21 and the water hole 13 can be fully coordinated and connected.
