[0036] Initially, the bellows 4 is externally received in the collecting container, and the pipe joint is first moved between the upper and lower conical frames 18, and the hole position is made to correspond to the drill rod 7, and the electric push rod 6 is started. The telescopic rod 11 of the electric push rod 6 is extended to drive the upper and lower mounting frames 5 to move in a direction close to each other, and the mounting frames 5 drive the upper and lower electric rotating cylinders 3 to move in a direction close to each other, and the electric rotating cylinder 3 drives the upper and lower conical frames 18 to move in a direction close to each other, and the conical frame 18 moves to contact the pipe joint, and the pipe joint squeezes the conical frame 18, so that the conical frame 18 moves to push the six cross rods 181 to move in a direction close to each other, and the compression spring 182 is compressed, and the cross rod 181 moves to contact the pipe joint, and the cross rod 181 centers the pipe joint. Position, close the electric push rod 6, and then start the electric screw 17. The electric screw 17 rotates forward to drive the frame 12 to move to the left to cover the pipe joint. The frame 12 drives the movable frame 8 to move to the left. The movable frame 8 drives the drive motor 71 to move to the left through the electric mounting frame 81. The drive motor 71 drives the drill rod 7 to move to the left through the inner hexagonal tube 72. The drill rod 7 and the frame 12 move to the left synchronously. At the same time, the frame 12 also drives the arc cover plate 13 to move to the left. The arc cover plate 13 drives the arc plate 15 to move to the left. Since the arc plate 15 is in contact with the lower fixed plate 2, the lower fixed plate 2 pushes the arc plate 15 moving to the left to swing. The swing of the arc plate 15 drives the arc cover plate 13 to swing. The connecting spring 14 is stretched, and the arc cover plate 13 swings to close the frame 12 and close it. The electric screw 17 is then started, and the drive motor 71 is started to drive the inner hexagonal cylinder 72 to rotate. The rotation of the inner hexagonal cylinder 72 drives the drill rod 7 to rotate. The electric mounting frame 81 is started to slide leftward, and the drive motor 71 and the inner hexagonal cylinder 72 drive the drill rod 7 to slide leftward. The drill rod 7 moves leftward to open a hole for the pipe joint. The frame 12, the arc-shaped cover plate 13 and the elastic cloth 16 can block the debris ejected during the hole opening process. The blocked debris passes through the lower conical frame 18 and falls into the lower electric rotating cylinder 3. The debris in the lower electric rotating cylinder 3 falls into the collection container through the bellows 4 to prevent the debris from ejecting to the surrounding working area and affecting the environment. There is no need to manually remove the debris, thereby ensuring a good working environment and production efficiency. At the same time, the air pump 192 is started to The air is discharged into the hose 191, and the air in the hose 191 is discharged into the sealing cover 19. The sealing cover 19 discharges the air into the pipe joint through the upper electric rotating cylinder 3. The air blows the debris in the pipe joint due to the hole opening downward, and the debris blown downward continues to be discharged into the collection container through the lower electric rotating cylinder 3 and the bellows 4 for collection. When a hole is opened in the pipe joint, the electric installation frame 81 is started to drive the drill rod 7 to move right and reset through the driving motor 71 and the hexagonal inner cylinder 72, and then the electric screw 82 is started to rotate and drive the movable frame 8 to move up and down. The movable frame 8 drives the electric installation frame 81 to move up and down, which makes the drill rod 7 move up and down to the next hole opening position, and the electric screw 82 is closed. According to the above operation, the pipe joint can continue to be opened.When the pipe joint needs to be rotated to drill holes at other positions, the electric rotating cylinder 3 is started to rotate and drive the cone frame 18 to rotate. The cone frame 18 rotates and drives the pipe joint to rotate. When the pipe joint rotates so that the next drilling position is on the right, the electric rotating cylinder 3 is closed. When the drilling on the pipe joint is completed, the drive motor 71 is turned off, the drill rod 7 stops rotating, and the air pump 192 is turned off at the same time. The hose 191 stops exhausting air into the sealing cover 19, and the electric screw 17 is started to reverse and drive the frame 12 to move right and reset. The frame 12 stops covering the pipe joint. The frame 12 moves to the right and drives the arc cover 13 to move to the right. The arc cover 13 moves to the right and drives the arc The plate 15 moves to the right, and due to the action of the connecting spring 14, the arc cover plate 13 swings in the opposite direction to reset and stop to close the frame 12. The electric screw rod 17 is closed, and the electric push rod 6 can be started to drive the upper and lower mounting frames 5 to move and reset in the direction away from each other. The mounting frame 5 drives the upper and lower electric rotating cylinders 3 to move and reset in the direction away from each other, which also makes the cone frame 18 move and reset to break contact with the pipe joint. The cone frame 18 loosens the pipe joint. Due to the action of the compression spring 182, the six cross rods 181 move and reset in the direction away from each other. The cross rod 181 drives the upper and lower cone frames 18 to slide and reset, and the pipe joint with the hole completed can be removed.

When the driving component is in operation, the driving component can drive the U-shaped The brush 211 moves up and down; the driving assembly includes a vertical rod 212, a straight hole plate 213, a rotating rod 214, a disc 215, a contact rod 216 and a rotating blade 217. The vertical rod 212 is fixedly connected to the right side of the top of the U-shaped brush 211, and the top of the vertical rod 212 is fixedly connected to the straight hole plate 213. The rotating rod 214 is rotatably connected to the upper right side of the cylinder 202, and the disc 215 is fixedly connected to the left end of the rotating rod 214. The contact rod 216 is fixedly connected to the eccentric position of the left side of the disc 215. The contact rod 216 is located in the straight hole plate 213. When the contact rod 216 rotates, the contact rod 216 can drive the straight hole plate 213 to move up and down.

[0040] When the air pump 192 is started, the air pump 192 also discharges air into the air outlet pipe 218. The air in the air outlet pipe 218 flows through the discharge frame 219, making the fixed frame 21 in a negative pressure state. At the same time, the air flow in the air outlet pipe 218 drives the rotating blades 217 to rotate. The rotation of the rotating blades 217 drives the rotating rod 214 to rotate through the synchronous belt assembly. The rotating rod 214 drives the disc 215 to rotate. The disc 215 drives the contact rod 216 to rotate. The contact rod 216 drives the straight hole plate 213 to move up and down. The straight hole plate 213 drives the vertical rod 212 to move up and down. The vertical rod 212 drives the U-shaped brush 211 to move up and down. When the drill rod 7 after use rotates to contact with the U-shaped brush 211, the U-shaped The brush 211 moves up and down to remove the debris remaining on the drill rod 7, and the removed debris falls into the fixed frame 21. The debris in the fixed frame 21 is discharged into the discharge frame 219 under the action of negative pressure, and the debris in the discharge frame 219 is discharged into the air outlet pipe 218, and the air outlet pipe 218 discharges the debris. When the air pump 192 is turned off, the air stops being discharged into the air outlet pipe 218, and the rotating blade 217 also stops rotating, and the rotating blade 217 stops driving the rotating rod 214 to rotate, and the rotating rod 214 stops driving the disc 215 to rotate, and the disc 215 stops driving the straight hole plate 213 to move up and down through the contact rod 216, and the straight hole plate 213 stops driving the U-shaped brush 211 to move up and down through the vertical rod 212. In this way, it can prevent the debris remaining on the drill rod 7 from affecting the effect of subsequent use, thereby ensuring the effect of subsequent use of the drill rod 7.
