[0026] Reference Figure 2-3As shown in this embodiment: the lever-lifting mechanism 4 includes a lifting frame 41, a lifting cylinder 42 is provided on one side of the lifting frame 41, the lifting cylinder 42 is installed on the outer surface of the base 1, the output rod of the lifting cylinder 42 is fixedly connected to one side of the top of the lifting frame 41, a telescopic frame 43 is provided at the top of the lifting frame 41, a telescopic cylinder 44 is provided on one side of the telescopic frame 43, the output end of the telescopic cylinder 44 is fixedly connected to one end of the telescopic frame 43, a mechanical arm 45 is fixedly connected to one end of the telescopic frame 43, and two second hydraulic rods 46 are provided at the bottom end of the mechanical arm 45. The output rods of the second hydraulic rods 46 are fixedly connected to clamps. When the rod-taking mechanism 4 operates, the telescopic cylinder 44 operates to shorten and control the telescopic rod to move towards the placement box 21, so that the bottom clamping block 47 is located above the top of the placement box 21. Then, the lifting cylinder 42 on one side of the lifting frame 41 operates to shorten and control the lifting frame 41 to descend, so that the two clamping blocks 47 are located on the left and right sides of the drill rod respectively. Then, the two second hydraulic rods 46 operate to extend and control the two clamping blocks 47 to clamp on both sides of the outer surface of the drill rod respectively. The lifting cylinder 42 operates again to extend and control the lifting frame 41 to rise. The telescopic cylinder 44 operates to extend and control the telescopic rod to extend and move the arm 45 to the upper rod mechanism 3.

[0027] Reference Figure 2-3As shown in this embodiment: the upper rod mechanism 3 includes a slide 31, which is fixed to the outer surface of the base 1. A power head 33 is slidably connected to the outer surface of the slide 31. A feed cylinder 32 is installed inside the slide 31. The output rod of the feed cylinder 32 is fixedly connected to one side of the bottom end of the power head 33. A chuck 34 is installed on one side of the power head 33. Several hydraulically driven chucks are installed inside the chuck 34. A collet 35 is installed at the end of the slide 31 away from the power head 33. A hydraulically driven chuck is installed inside the collet 35. When installing the drill rod, a drill rod is moved above the slide 31 by the rod-taking mechanism 4. Then, the feed cylinder 32 operates to drive the power head 33 to move towards the drill rod, so that the chuck 34 is fitted onto the outer surface of one end of the drill rod. Then, the chuck 34 is controlled to operate so that the chucks clamp the drill rod. The feed cylinder 32 is then controlled to operate so that the power head 33 moves towards the collet 35 to install the drill rod. The drill rod passes through the chuck 35. The chuck 35 is operated to clamp the drill rod using the chuck inside the chuck 35. Then, the chuck 34 is operated to release the drill rod. The feed cylinder 32 is operated to control the power head 33 to move away from the chuck 35. Then, the rod removal mechanism 4 moves the next drill rod to the top of the slide block 31. The feed cylinder 32 is operated to drive the power head 33 to move towards the drill rod, so that the chuck 34 is fitted onto the outer surface of one end of the drill rod. Then, the chuck 34 is operated to clamp the drill rod. Then, the feed cylinder 32 is operated to drive the power head 33 to move towards the chuck 35 so that one end of the second drill rod is fitted onto the tail end of the first drill rod. Then, the power head 33 is operated to drive the drill rod to rotate and connect with the threaded connection of the first drill rod. After the connection is completed, the chuck 35 is controlled to release the drill rod. The feed cylinder 32 is operated to control the power head 33 and the two connected drill rods to continue to move forward. This step can be repeated to install the remaining drill rods.

[0028] Reference Figure 1-5As shown in this embodiment: the feeding mechanism 2 includes a placement box 21, the bottom end of which is fixedly connected to the surface of the base 1. The bottom end of the inner wall of the placement box 21 is inclined. A sliding plate 24 is slidably connected to the inner wall of the placement box 21. A support rod 23 is fixedly connected to one side of the sliding plate 24. A first hydraulic rod 22 is provided on the outer surface of the base 1. The output rod of the first hydraulic rod 22 is fixedly connected to one side of the support rod 23. Several support blocks 25 are fixedly connected to the top of the sliding plate 24. The top of the support blocks 25 has a groove. When using the feeding mechanism 2, several drill rods are placed inside the placement box 21. The sliding plate 24 is located on the lower side of the bottom end of the inner wall of the placement box 21. The position of the drill rod is restricted. When the drill rod needs to be removed, the first hydraulic rod 22 is controlled to retract, causing the support rod 23 and the slide plate 24 to move downward. This moves the support block 25 at the top of the slide plate 24 to below the bottom of the inner wall of the placement box 21. Then, the first hydraulic rod 22 is operated to extend, causing the support rod 23 and the slide plate 24 to move upward. The support block 25 at the top of the slide plate 24 lifts up one of the drill rods located above the support block 25, and the drill rod stops inside the groove at the top of the support block 25. At the same time, the upward movement will push away the remaining drill rods outside the support block 25. After the support block 25 moves to the top of the placement box 21, the operation of the first hydraulic rod 22 stops.

[0029] Reference Figure 2-5 As shown in this embodiment: the top two edges of the support block 25 are arc-shaped. By setting the top two edges of the support block 25 to be arc-shaped, it is easier to push away excess drill rods when the support block 25 moves upward. An auxiliary rod 26 is fixedly connected to one side of the slide plate 24. A rectangular groove 27 is opened on one side of the bottom of the placement box 21. The outer surface of the auxiliary rod 26 is L-shaped. The end of the auxiliary rod 26 near the slide plate 24 has an upward sloping surface. When the slide plate 24 moves downward, the auxiliary rod 26 will enter the rectangular groove 27. When the slide plate 24 moves upward, the upward sloping end of the auxiliary rod 26 can further push away the drill rods on one side of the slide plate 24, preventing excess drill rods from following the slide plate 24. 4. After rising, the subsequent fall causes an impact between drill rods or between the drill rod and the placement box 21. The inclined surface of the auxiliary rod 26 away from the slide plate 24 faces downward. When the slide plate 24 moves downward, the inclined surface of the auxiliary rod 26 will push away the drill rod located at the rectangular groove 27, thus preventing the drill rod from obstructing the descent of the slide plate 24 and the auxiliary rod 26. Two support rods 28 are fixedly connected to the outer surface of the support rod 23. The ends of the two support rods 28 away from the support rod 23 are respectively fixedly connected to both sides of the output rod of the first hydraulic rod 22. By setting the support rods 28, the connection between the support rod 23 and both sides of the output rod of the first hydraulic rod 22 can be reinforced, thereby improving the stability of the connection structure between the output rods of the first hydraulic rod 22.

[0030] Working principle: After the drilling rig is installed underground in the coal mine, several drill rods are placed inside the placement box 21. The sliding plate 24, located on the lower side of the inner wall of the placement box 21, restricts the position of the drill rods. When a drill rod needs to be removed, the first hydraulic rod 22 is operated to retract, causing the support rod 23 and the sliding plate 24 to move downwards. This moves the support block 25 at the top of the sliding plate 24 to below the bottom of the inner wall of the placement box 21. Then, the first hydraulic rod 22 is operated again to extend, causing the support rod 23 and the sliding plate 24 to move upwards. The support block 25 at the top of the sliding plate 24 lifts one drill rod located above the support block 25, causing the drill rod to stop inside the groove at the top of the support block 25. At the same time, the upward movement pushes away the remaining drill rods outside the support block 25. The support block 25 moves to the position below the bottom of the inner wall of the placement box 21. After the first hydraulic rod 22 stops operating above the top of the placement box 21, the rod-taking mechanism 4 operates. The telescopic cylinder 44 shortens, controlling the telescopic rod to move towards the placement box 21, placing the bottom clamping block 47 above the top of the placement box 21. Then, the lifting cylinder 42 on one side of the lifting frame 41 shortens, controlling the lifting frame 41 to descend, placing the two clamping blocks 47 on the left and right sides of the drill rod respectively. Next, the two second hydraulic rods 46 extend, controlling the two clamping blocks 47 to clamp the outer surface of the drill rod on both sides respectively. The lifting cylinder 42 extends again, controlling the lifting frame 41 to rise. The telescopic cylinder 44 extends, controlling the telescopic rod to extend, moving the arm 45 to the upper rod mechanism 3. When installing the drill rod, the rod-taking mechanism 4 moves one drill rod to the slide block 31. Above, the feed cylinder 32 operates, driving the power head 33 to move towards the drill rod, causing the chuck 34 to fit onto the outer surface of one end of the drill rod. Then, the chuck 34 is controlled to operate, causing the chuck to clamp the drill rod. The feed cylinder 32 continues to operate, driving the power head 33 towards the chuck 35, allowing the drill rod to pass through the chuck 35. The chuck 35 operates, using the chuck inside the chuck 35 to clamp the drill rod. Then, the chuck 34 is operated to release the drill rod. The feed cylinder 32 controls the power head 33 to move away from the chuck 35. Then, the rod removal mechanism 4 moves the next drill rod above the slide block 31. The feed cylinder 32 operates, driving the power head 33 towards the drill rod, causing the chuck 34 to fit onto the outer surface of one end of the drill rod. Then, the chuck 34 is controlled to operate, causing the chuck to... Clamp the drill rod, then continue to operate the feed cylinder 32 to move the power head 33 towards the chuck 35 so that one end of the second drill rod is fitted onto the tail end of the first drill rod. Then operate the power head 33 to rotate the drill rod and thread it onto the first drill rod. After the connection is completed, control the chuck 35 to release the drill rod. Operate the feed cylinder 32 to control the power head 33 and the two connected drill rods to continue moving forward. Repeat this step to install the remaining drill rods. When removing the drill rod, operate the feed cylinder 32 to move the power head 33 towards the drill rod so that the chuck inside the chuck 34 clamps the drill rod. At the same time, operate the chuck 35 so that the chuck inside the chuck 35 clamps the other end of the drill rod. Then operate the power head 33 to rotate one drill rod to release the threaded connection between the two drill rods.Subsequently, the lifting cylinder 42 controls the arm 45 to descend, causing the two clamping blocks 47 to be positioned on either side of the disconnected drill rod. The second hydraulic rod 46 extends and clamps the drill rod through the clamping blocks 47. With the help of the chuck 34 to fix the drill rod, the feed cylinder 32 moves away from the drill rod, and the upper rod mechanism 3 moves the drill rod into the placement box 21.
