[0049] The intelligent drilling and milling device is placed just above the conveyor belt to be drilled, with the two long sides of the bracket 1 located on both sides of the conveyor belt, and the linear guide rail 20 is parallel to the conveyor belt. The PLC of the intelligent drilling and milling device is used to start the No. 1 power source 21, which drives the driving wheel 23 to rotate, and the driving wheel 23 drives the driven wheel 24 to rotate through the transmission belt 25, and the driven wheel 24 drives the No. 1 screw rod 26 to rotate, so that the No. 1 screw rod nut 27 moves forward and backward on the No. 1 screw rod 26, and the moving part 3 follows the No. 1 screw rod nut 27 to move forward and backward along the linear guide rail 20, and the laser distance sensor of the moving part 3 measures the distance from the conveyor belt The maximum distance between them is used to identify the position of the conveyor belt groove. When the drill bit 3345 reaches the conveyor belt groove, the No. 1 power source 21 is turned off, the moving part 3 stops moving, and the No. 2 power source 313 is started. The No. 2 power source 313 drives the No. 2 screw rod 314 to rotate, so that the No. 2 screw rod nut 315 moves left and right along the No. 2 screw rod 314. When the No. 2 screw rod nut 315 drives the up and down moving part 32 to move to the appropriate position, the No. 2 power source 313 is turned off, the up and down moving part 32 stops moving, and the No. 3 power source 323 is started. The No. 3 power source 323 drives the No. 3 screw rod 324 to rotate, so that the No. 3 screw rod nut 325 moves up and down along the third screw rod 324. When the third screw rod nut 325 drives the drilling part 33 to move to a suitable position, the third power source 323 is turned off, the drilling part 33 stops moving, and the fourth power source 3342 and the fan 3335 are started at the same time. The fourth power source 3342 drives the first gear 3343 to rotate, the first gear 3343 drives the second gear 3344 to rotate, and the second gear 3344 drives the drill bit 3345 to rotate. When the drill bit 3345 rotates, it drills a hole in the conveyor belt. The spur 3346 reduces the contact surface between the drill bit 3345 and the conveyor belt, so that the pressure between the two is increased. It is more conducive to drilling holes in the conveyor belt and prolongs the service life of the drill bit 3345. When the fan 3335 rotates, the air in the dust collecting cylinder 3331 is extracted, and negative pressure is formed at the connecting pipe 3336. The air at the end of the drill bit 3345 is sucked into the dust collecting cylinder 3331 through the drill hole 3347 through the connecting pipe 3336, and then filtered by the filter layer 3334 and discharged from the top of the dust collecting cylinder 3331. As the drilling progresses, a large amount of debris is generated on the conveyor belt. The debris is entrained by the air at the end of the drill bit 3345 and enters the drill hole 3347, and then enters the dust collecting cylinder 3331 through the connecting pipe 3336 for collection.When the dust collecting cylinder 3331 is full of debris, the fourth power source 3342 and the fan 3335 are turned off, the drill 3345 stops drilling, the chip outlet cover 3333 is unscrewed, and the debris flows out through the chip outlet 3332 and falls into a specific container. After all the debris flows out, the chip outlet cover 3333 is screwed on. After the fan 3335 works for a period of time, the filter layer 3334 is full of debris and loses its filtering effect on the air. The old filter layer 3334 is pulled out from the notch on the side of the dust collecting cylinder 3331, and a new filter layer 3334 is inserted. The fourth power source 3342 and the fan 3335 are turned on again, and the conveyor belt can continue to be drilled. ;
