The drilling system includes a drill tower, drill rod, and drill bit, in which the drill bit directly contacts the rock or soil for crushing and sampling.

[0004] When existing mineral geological exploration drilling rigs are in use, the electric motor in the power system provides power to the drilling rig. Then, the drill rod and drill bit in the drilling rig break up and sample the soil. However, when the drill rod needs to be maintained and repaired after long-term use, the workers need to use special tools to disassemble the entire drilling system and then disassemble the drill rod. This increases the difficulty of disassembling the drill rod, increases the workload of the workers, and reduces the efficiency of drill rod maintenance and repair. Utility Model Content

[0031] Please see Figure 1-4 This utility model provides a technical solution: a mineral geological exploration drilling rig, including a base 1 and a second electric motor 9;

[0032] The second electric motor 9 is equipped with a limit device;

[0033] The limiting device includes a fixed mounting base 21, a fixed base 10, and two protective shells 19. The upper surface of the fixed mounting base 21 is fixedly connected to the output end of the second motor 9. A sliding block 16 is fixedly connected to the upper surface of the fixed base 10. A sliding block groove 18 is formed on the lower surface of the fixed mounting base 21. The outer wall of the sliding block 16 is slidably connected to the inside of the sliding block groove 18. The two protective shells 19 are fixedly connected to the outer walls on both sides of the fixed mounting base 21. A first limiting block groove 15 is formed on the outer walls on both sides of the sliding block 16. The outer walls of the two protrusions on the sliding block 16 are slidably connected to the inside of the two grooves inside the sliding block groove 18. A first limiting block groove 15 is formed on the inside of both sides of the sliding block groove 18. There is a second limiting block groove 17, and the interior of each of the two second limiting block grooves 17 is slidably connected to a limiting block 13. The ends of the two limiting blocks 13 near the first limiting block groove 15 are slidably extended into the interior of the sliding block groove 18 and respectively contact the inner wall of the corresponding first limiting block groove 15. The interiors of the two protective shells 19 are respectively connected to the interiors of the corresponding second limiting block grooves 17. A drill rod 11 is installed on the lower surface of the fixed base 10. The outer walls of the two protective shells 19 are threadedly connected to rotating threaded rods 14. The ends of the two rotating threaded rods 14 near the limiting block 13 are threadedly extended into the interior of the second limiting block groove 17 and respectively rotatably connected to one side of the corresponding limiting block 13.

[0034] The base 1 has a support column 3 fixedly connected to its upper surface. A threaded rod 22 is rotatably connected to the outer wall of the support column 3 via a groove. A sliding seat 4 is threadedly connected to the outer wall of the threaded rod 22. Limiting grooves 2 are formed on both sides of the outer wall of the support column 3. The outer walls of the protrusions on both sides of the sliding seat 4 are slidably connected to the corresponding limiting grooves 2. A first motor 5 is fixedly connected to the upper surface of the support column 3. The output end of the first motor 5 extends rotatably into the interior of the support column 3 and is fixedly connected to one end of the corresponding threaded rod 22. A mounting groove 12 is formed on the outer wall of the sliding seat 4 on the side away from the support column 3. The groove 12 has a sliding connection to a mounting base 8. The outer wall of the upper protrusion of the mounting base 8 is slidably connected to the groove on one side of the sliding base 4. A level 6 is installed on the upper surface of the sliding base 4. The outer wall of the second motor 9 is fixedly connected to the outer wall of the mounting base 8 on the side away from the sliding base 4. Two fixing bolts 7 are threadedly connected to the upper surface of the upper protrusion of the mounting base 8. Two fixing bolt grooves 20 are opened on the upper surface of the sliding base 4 on the side close to the mounting base 8. The ends of the two fixing bolts 7 close to the fixing bolt grooves 20 are threaded to the outside of the upper protrusion of the mounting base 8 and respectively connected to the internal threads of the corresponding fixing bolt grooves 20.

[0035] Furthermore, when using this device, it is started by connecting to an external power source. First, the device is checked for levelness by observing the level indicator 6. If it is not level, it is adjusted to levelness using external tools. Then, the output of the second motor 9 rotates, causing the fixed mounting base 21 to rotate, which in turn rotates the fixed base 10. Then, the rotation of the fixed base 10 rotates, causing the drill rod 11 to rotate, which in turn rotates the output of the first motor 5, causing the threaded rod 22 to rotate. Then, the rotation of the threaded rod 22 rotates, causing the sliding seat 4 to move downwards, which in turn moves the second motor 9 downwards. This will cause the drill rod 11 to move downwards and contact the ground. Then, through cooperation, the drill rod 11 will break up and sample the soil. At the same time, the outer wall of the drill rod 11 is provided with a spiral groove, which makes it easy to leave the sample inside the spiral groove of the drill rod 11. Then, when it is necessary to remove the drill rod 11, turn the threaded rod 14 to rotate and move it in the opposite direction, which will cause the limiting block 13 to move in the opposite direction, while making its other end of the outer wall disengage from the inside of the first limiting block groove 15. Then, pull the fixing seat 10 to remove the first limiting block groove 15 and the drill rod 11 from the fixing mounting seat 21.

[0036] By rotating the threaded rod 14 in the limiting device, the limiting block 13 moves in the opposite direction, causing its other outer wall to disengage from the inside of the first limiting block groove 15. Then, by pulling the fixed seat 10, the first limiting block groove 15 and the drill rod 11 can be removed from the fixed mounting seat 21. This makes disassembling the drill rod 11 simple and quick, thus avoiding the need to disassemble the entire drilling system before disassembling the drill rod 11. This effectively improves the maintenance and repair efficiency of the drill rod 11 and reduces the workload of the workers. The output end of the first motor 5 rotates, driving the threaded rod 22 to rotate. Then, the rotation of the threaded rod 22 drives the sliding seat 4 to move downward, which in turn drives the second motor 9 to move downward. This causes the drill rod 11 to move downward and contact the ground, making it easy to adjust the height of the drill rod 11. This effectively improves the practicality and flexibility of the equipment and increases the work efficiency of the workers.

[0037] Working principle: First, the equipment is checked for levelness by observing the level 6. If it is not level, it is adjusted to levelness using external tools. Then, the output of the second motor 9 rotates, driving the fixed mounting base 21 to rotate, which in turn drives the fixed base 10 to rotate. The rotation of the fixed base 10 then drives the drill rod 11 to rotate, which in turn drives the threaded rod 22 to rotate through the output of the first motor 5. The rotation of the threaded rod 22 then drives the sliding seat 4 to move downwards, which in turn drives the second motor 9 to move downwards. This causes the drill rod 11 to move downwards and contact the ground. The drill rod 11 then breaks up and samples the soil. The outer wall of the drill rod 11 has a spiral groove, which makes it easy to leave the sample inside the spiral groove of the drill rod 11. When it is necessary to remove the drill rod 11, the threaded rod 14 is turned and rotated in the opposite direction, which causes the limiting block 13 to move in the opposite direction, while the outer wall of its other end disengages from the inside of the first limiting block groove 15. Then, the fixed base 10 is pulled to remove the first limiting block groove 15 and the drill rod 11 from the fixed mounting base 21.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
