The two fixed rods 9 are both slidably connected to the moving block 8. A water collecting block 10 is fixedly installed on the lower side of the moving block 8. Three high-pressure nozzles 11 are fixedly installed on the lower side of the water collecting block 10. A water pipe 12 is fixedly installed on the side wall of the water collecting block 10. The water pipe 12 is externally connected to a water pump. The water pump is used to The water is pumped into the water pipe 12, and then enters the water collecting block 10 and is sprayed out from the high-pressure nozzle 11. The high-pressure nozzle 11 contains a high-pressure pump, which can turn the water into high pressure, so that it is sprayed out through the tiny holes at the nozzle. The water sprayed by the high-pressure nozzle 11 here will not cause damage to the vacuum suction roller body 2. This is the existing technology and will not be elaborated on. The side wall of the moving block 8 is fixedly connected with two clips 29. The two clips 29 can clamp and fix the water pipe 12, thereby avoiding interference caused by the movement of the water pipe 12.

[0022] A cleaning structure is installed on the moving block 8, and the cleaning structure includes a support block 13 fixedly connected to the side wall of the moving block 8, and a fixed block 14 is fixedly connected to the side wall of the support block 13. A long slider 15 is slidably connected to the inner side of the fixed block 14, and an electric hydraulic device 30 is fixedly installed on the upper side of the fixed block 14. The electric hydraulic device 30 is a device that converts electrical energy into hydraulic energy and then outputs mechanical work through a hydraulic actuator. It consists of an electric motor, a hydraulic pump, an oil tank and a control valve. It can extend the output end and has a self-locking function. This is a prior art and will not be described in detail. The output end of the electric hydraulic device 30 is fixedly connected to the long slider 15, and the movement of the long slider 15 can be controlled by the electric hydraulic device 30, so that the long slider 15 can be retracted when cleaning is not required. , which will not affect the normal use of the vacuum suction roller body 2. A cleaning plate 16 is fixedly connected to the lower side of the long slider 15. The side wall of the support block 13 is rotatably connected to two hollow shafts 17. The inner sides of the two hollow shafts 17 are slidably connected with slide rods 18. The lower ends of the two slide rods 18 are fixedly connected with circular plates 19. The two slide rods 18 are rotatably connected to the cleaning plate 16. The two circular plates 19 and the lower sides of the cleaning plate 16 are fixedly connected with cleaning brushes. A spur gear 20 is fixedly sleeved on the outer side of one of the hollow shafts 17. A support rod 21 is fixedly connected to the side wall of the fixed bracket 1.

Two blocks 31 are fixedly installed on the inside of the water collecting block 10, and the block 31 can limit the moving distance of the adjustment block 25. An extrusion block 26 is fixedly connected to the side wall of the movable plate 24, and a support rod 27 is fixedly connected between the two fixed plates 5. An extrusion plate 28 is fixedly connected to the upper side of the support rod 27. The middle protrusion of the extrusion plate 28 can squeeze the extrusion block 26 upward through the inclined surfaces on both sides.

[0024] In the present utility model, first, the staff starts the water pump to make the water pipe 12 deliver water to the water collecting block 10, and at the same time starts the servo motor 6 to rotate the ball screw 7. The rotation of the ball screw 7 can make the moving block 8 move. When it moves to the other end, the ball screw 7 is controlled by the servo motor 6 to rotate in the opposite direction, so that the moving block 8 moves in the opposite direction. This reciprocating motion makes the moving block 8 reciprocate, and the long slider 15 is controlled to move downward by the electric hydraulic device 30, so that the cleaning plate 16 is close to the vacuum suction roller body 2. When the moving block 8 moves, the spur gear 20 drives one of the hollow shafts 17 to rotate through the spur rack 22, and the hollow shaft 17 drives the other hollow shaft 17 to rotate through the pulley assembly 23. The two hollow shafts 17 respectively drive The movable slide bar 18 rotates, thereby causing the slide bar 18 to drive the cleaning brush to rotate through the circular plate 19. The rotating cleaning brush can extend into the circular hole of the vacuum suction roller body 2, thereby performing better cleaning. The slide bar 18 is slidably connected to the hollow shaft 17, so the slide bar 18 can move with the movement of the long slider 15 without affecting the rotation of the hollow shaft 17. When the moving block 8 moves, the extrusion block 26 is also squeezed upward by the extrusion plate 28, so that the extrusion block 26 drives the movable plate 24 to move upward. The upward movement of the movable plate 24 causes the adjusting block 25 to partially block the water pipe 12, thereby reducing the water output of the water pipe 12, so that when the moving block 8 moves to the middle position that is easy to clean, the water output can be reduced, thereby reducing the waste of water resources.
