[0020] Referring to

[0021] Please refer to Figures 1-4, the embodiments provided by the present utility model: An open-pit mining mountain perforation device, which includes a limit frame 1 and a limit frame 2 movably connected in the middle of the limit frame 1. The top end of the limit frame 1 is fixedly provided with a servo motor 3 through bolts. The output end of the servo motor 3 is fixedly provided with a threaded screw rod 4. The other end of the threaded screw rod 4 is rotatably connected to the surface of the base 8. A screw rod slide 5 is fixedly provided on the side wall of the limit frame 2. The screw rod slide 5 moves on the outer surface of the threaded screw rod 4. Starting the servo motor 3 can drive the threaded screw rod 4 to rotate, thereby driving the screw rod slide 5 to move vertically along the threaded screw rod 4, improving the convenience of height adjustment of the limit frame 2. A limit plate 15 is fixedly provided on the side wall of the limit frame 2 away from the screw rod slide 5. A limit rod 14 is fixedly provided on the inner side wall of the limit frame 2 close to the limit plate 15. The bottom end of the limit rod 14 is fixedly provided at the top end of the base 8. The limit plate 15 is slidably connected to the outer surface of the limit rod 14. The limit rod 14 and the limit plate 15 can limit the lateral displacement of the other end of the limit frame 2, improving the stability of the vertical movement of the limit frame 2. A servo motor 6 is fixedly provided at the inner bottom of the limit frame 2. The output end of the servo motor 6 is fixedly provided with a chuck 7 through a coupling. The bottom end of the limit frame 1 is fixedly provided with a base 8 by welding. A notch 9 is opened in the middle of the base 8. A limit sleeve 11 is inserted into the notch 9. The limit sleeve 11 is sleeved on the outer surface of the chuck 7. Two notches 10 are symmetrically opened on the inner side wall of the notch 9. Limit plates 17 are fixedly provided on the side walls of the limit sleeve 11 close to the notches 10. Both the limit plate 17 and the limit sleeve 11 are made of stainless steel. The limit sleeve 11 is in a flared shape and is fixedly connected to the limit plate 17 to form an integral structure, improving the stability of the insertion protection of the limit sleeve 11. The limit plate 17 and the limit sleeve 11 are respectively adapted to the internal dimensions of the notch 10 and the notch 9 in sequence, improving the convenience of installation and positioning of the limit sleeve 11. When the blade foot at the bottom end of the limit sleeve 11 is inserted into the ground surface, it can isolate the ground surface and the opened hole groove. When the chuck 7 lifts the opened hole groove, it can prevent the crushed stones on the ground surface from entering the hole groove, thereby improving the quality of the hole opening.

[0022] Rollers 12 are rotatably connected to the four corner positions at the bottom end of the base 8, improving the convenience of moving the device. Pins 13 are inserted into the surface of the base 8 close to the rollers 12 to improve the stability of the device during perforation. Cylinders 16 are fixedly provided at the inner bottoms of the two notches 10. The output ends of the cylinders 16 are symmetrically and fixedly provided at the bottom ends of the limit plates 17 in sequence, improving the convenience of inserting the limit sleeve 11.

[0023] Working principle: When this kind of mountain piercing device for open-pit mining is in use, the operator first connects to an external power supply, fixes the device through the roller 12 and moves it to the designated position, inserts the pin 13 through the base 8 in sequence and plugs it into the ground surface to prevent the device from moving. Starting the second servo motor 6 can drive the chuck 7 to rotate at high speed, and then starting the first servo motor 3 drives the threaded screw rod 4 to rotate, so as to drive the limit frame 2 to move vertically downward inside the limit frame 1, so that the chuck 7 rotates downward to open a hole. The limit sleeve 11 is sleeved on the outer surface of the chuck 7 in a horn shape. The second limit plate 17 and the limit sleeve 11 are respectively adapted to the internal dimensions of the second notch 10 and the first notch 9, which improves the convenience of installing and positioning the limit sleeve 11. When the blade foot at the bottom end of the limit sleeve 11 is inserted into the ground surface, it can isolate the ground surface and the opened hole groove. When the chuck 7 is lifted out of the opened hole groove, it can prevent the crushed stones on the ground surface from entering the hole groove, thereby improving the quality of the hole opening.

[0024] Secondly, the operator can drive the limit sleeve 11 to move vertically by starting the cylinder 16, which improves the stability and efficiency of the insertion of the limit sleeve 11.
