At the same time, the servo motor 3 524 causes the rotating shaft 4 522 to rotate, thereby causing the grinding rod 523 to rotate, thereby grinding the cylindrical steel pipe. In order to avoid grinding the non-rusted parts, the centrifugal force causes the telescopic spring 2 5210 to stretch. At the same time, the electromagnetic ball 5211 has no repulsive effect on rusty iron. After the iron filings are ground, a repulsive force is generated on the steel pipe, thereby pushing the grinding rod 523 to move backward and separate from the steel pipe. At the same time, the servo motor 4 527 drives the fan shaft 528 and the fan blades 529 to rotate, thereby cooling the ground part to prevent deformation caused by excessive temperature during grinding.

[0025] The watering mechanism 53 includes a hanging plate 2 531, the lower surface of the hanging plate 2 531 is fixedly connected to a supporting plate 3 532, the upper surface of the supporting plate 3 532 is fixedly connected to a water tank 533, the lower surface of the supporting plate 3 532 is fixedly connected to a fixing plate 3 534, the outer surface of the fixing plate 3 534 is rotatably connected to a rotating shaft 535, the outer surface of the rotating shaft 535 is fixedly connected to a rotating water plate 536, and the lower surface of the rotating water plate 536 is fixedly connected to a high-pressure water gun 537. The rotating shaft 4 522 drives the baffle plate 2 to move during the movement. When the baffle plate 2 525 is not in contact with the rotating water plate 536, the high-pressure water gun 537 sprays water on the tool to remove the dust remaining on the tool. After the contact, the rotating shaft 535 and the rotating water plate 536 are rotated, thereby changing the angle of the high-pressure water gun 537, impacting the rusty steel plate, thereby removing impurities on the steel plate, and also having a cooling effect.

[0026] The water removal and cleaning mechanism 6 comprises a ball screw mechanism 61 , and a drying and scratching mechanism 62 is fixedly connected to the outer surface of the ball screw mechanism 61 .

[0027] The ball screw mechanism 61 includes a hanging plate three 611, an end of the hanging plate three 611 away from the protective shell 3 is fixedly connected to a support plate four 612, an end of the support plate four 612 away from the hanging plate three 611 is fixedly connected to a fixed block 613, an end of the fixed block 613 away from the support plate four 612 is rotatably connected to a screw 614, and an external motor drives the screw 614 to rotate, thereby driving the sliding block 621 to move.

[0028] The drying and rubbing mechanism 62 includes a sliding block 621, the inner surface of the sliding block 621 is fixedly connected to the outer surface of the lead screw 614, the outer surface of the sliding block 621 is fixedly connected to a telescopic spring 3 622, the end of the telescopic spring 3 622 away from the sliding block 621 is fixedly connected to an impact ball 623, the end of the sliding block 621 close to the telescopic spring 3 622 is fixedly connected to a drying device 624, the end of the sliding block 621 close to the drying device 624 is fixedly connected to a wire sheet 625, and the inner surface of the wire sheet 625 is rotatably connected to a rotating column 62 6. An impact spring 627 is fixedly connected to the outer surface of the rotating column 626. When the sliding block 621 moves, the iron wire sheet 625 scratches the iron filings that fall into the bottom of the steel plate during grinding, causing them to fall. At the same time, the impact ball 623 hits the cylindrical steel pipe. The impact generates vibrations that cause the firmly attached iron filings to fall. At the same time, the rotating column 626 rotates, driving the impact spring 627 to hit the iron wire sheet 625, causing the attached iron filings to fall, thereby preventing the scratching effect from weakening. At the same time, the drying device dries the falling moisture to prevent rusting again.

[0029] The specific workflow is as follows: During operation, the servo motor 414 drives the rotating shaft 413 to rotate, thereby driving the supporting plate 415 to rotate, and at the same time, the telescopic spring 417 pushes the baffle 416 to fix the bottom of the cylindrical steel plate, thereby driving the cylindrical steel plate to rotate, so that the steel plate and the grinding knife move in opposite directions, thereby removing rust and grinding the baffle, and further, the servo motor 424 drives the rotating shaft 423 to rotate, and drives the stirring plate 425 to rotate during the rotation process, thereby generating wind force to cool down the grinding tool and steel pipe above, preventing damage caused by excessive temperature, and at the same time, cleaning the iron filings dropped by grinding during the rotation process. The wind resistance generated by the rotation causes the rotating shaft 3 427 and the small leaf fan 426 to rotate. When the iron filings pass through them, the iron filings are crushed, thereby reducing the floor space and space occupied by the iron filings and facilitating the subsequent recycling of the staff. At the same time, the external motor causes the rotating disk 517 to rotate in the rotating groove 512. The centripetal force generated by the rotation causes the rotating shaft 4 522 to move on the slide 521. Since the slide 521 narrows from the outside to the inside, the rotating shaft 4 522 is limited. At the same time, the servo motor 3 524 causes the rotating shaft 4 522 to rotate, thereby causing the grinding rod 523 to rotate, thereby grinding the cylindrical steel pipe. In order to avoid grinding the non-rusted parts, the centrifugal force stretches the telescopic spring 2 5210, and the electromagnetic ball 5211 has no repulsive effect on the rusted iron. Therefore, after the iron filings are ground, a repulsive force is generated on the steel pipe, thereby pushing the grinding rod 523 to move backward and separate from the steel pipe. At the same time, the servo motor 4 527 drives the fan shaft 528 and the fan blades 529 to rotate. The shaft 4 522 drives the baffle 2 to move during the movement. When the baffle 2 525 is not in contact with the rotating water plate 536, the high-pressure water gun 537 sprays water on the tool to remove the dust remaining on the tool. After the contact, the shaft 5 535 and the rotating water plate 536 rotates, thereby changing the angle of the high-pressure water gun 537 to impact the rusty steel plate. Finally, the external motor drives the lead screw 614 to rotate, thereby driving the sliding block 621 to move. During the movement, the iron wire sheet 625 scratches the iron filings that fall into the bottom of the steel plate during grinding, causing them to fall. At the same time, the impact ball 623 impacts the cylindrical steel pipe, and the impact generates vibration to cause the firmly attached iron filings to fall. At the same time, the rotating column 626 rotates, driving the impact shrapnel 627 to impact the iron wire sheet 625, causing the attached iron filings to fall, preventing the scratching effect from weakening. At the same time, the drying device dries the falling moisture to prevent rusting again.
