[0002] Industrial sweepers are cleaning machines that integrate sweeping, vacuuming, and mopping. Powered by environmentally friendly new energy batteries, they are suitable for factory workshops, road sanitation, and other similar locations. Currently, when an industrial sweeper is working, a rotating brush sweeps dust, garbage, and debris from the ground to the vicinity of the machine's suction port. The suction system then draws this dust, garbage, and debris into a dust collection box or garbage bag inside the machine. A filtration system filters the intake air to prevent dust and debris from being released back into the air and causing secondary pollution. However, because the brush only has bristles, when stains on the ground are stubborn, cleaning is often incomplete, requiring cleaning personnel to use the brushes again for a second cleaning.

The center of the first arc-shaped plate 2 and the center of the second arc-shaped plate 4 are both coincident with the axis of the disc 1. The shape of the first arc-shaped plate 2 is the same as the shape of the second arc-shaped plate 4. A groove 6 is formed on the surface of the disc 1, and a positioning post 7 is attached to the inner wall of the groove 6. The upper surface of the first arc-shaped plate 2 and the upper surface of the second arc-shaped plate 4 are both attached to the positioning post 7. The bottom of the positioning post 7 is fixedly connected, and a retaining ring 8 is fixedly connected to the surface of the positioning post 7. The bottom of the retaining ring 8 is in contact with the upper surface of the disc 1. A connecting block 9 is fixedly connected to the upper surface of the disc 1. A bearing 10 is fixedly connected to the inner wall of the connecting block 9. A locking bracket 11 is fixedly connected to the inner ring of the bearing 10. A fixing post 12 is fixedly connected to the upper surface of the positioning post 7. A fixing groove 13 is opened on the upper surface of the fixing post 12. The inner wall of the fixing groove 13 and the bottom of the fixing post 12 are both in contact with the surface of the locking bracket 11. A column 14 is fixedly connected to the upper surface of the disc 1. A mounting plate 15 is fixedly connected to the upper surface of the column 14.
[0027] The locking bracket 11 includes a rotating rod 111, a cylinder 112, a side fixing block 113, a sliding sleeve 114, a first strip hole 115, a spring 116, a hollow block 117, and a lower fixing block 118. The inner wall of the rotating rod 111 is fixedly connected to the surface of the cylinder 112, the inner ring of the bearing 10 is fixedly connected to the surface of the cylinder 112, one end of the rotating rod 111 is fixedly connected to the surface of the side fixing block 113, and reinforcing blocks 21 are fixedly connected to the upper surface of both the rotating rod 111 and the upper surface of the side fixing block 113. The surface of the rotating rod 111 is in contact with the inner wall of the fixed groove 13. The first strip hole 115 is opened in the rotating rod 111. The surface of the rotating rod 111 is in contact with the inner wall of the sliding sleeve 114. The upper and lower sides of the hollow block 117 are fixedly connected to the inner wall of the sliding sleeve 114. The inner wall of the hollow block 117 is fixedly connected to the surface of the spring 116. Both ends of the spring 116 are fixedly connected to the inner wall of the first strip hole 115. The bottom of the sliding sleeve 114 is fixedly connected to the upper surface of the lower fixed block 118. The upper surface of the lower fixed block 118 is in contact with the bottom of the fixed post 12.
[0028] It should be noted that the first arc plate 2 and the second arc plate 4 placed at the bottom of the disc 1 can be positioned by the cooperation of the groove 6 and the positioning post 7. The first arc plate 2 and the second arc plate 4 are in contact with the disc 1 by the retaining ring 8 on the positioning post 7. The rotating rod 111 can rotate around the cylinder 112 by the bearing 10. When the side fixing block 113 is inserted into the fixing groove 13, the lower fixing block 118 at the bottom of the sliding sleeve 114 can contact the fixing post 12 by the spring 116. At this time, the side fixing block 113 is fixed in the fixing groove 13 by the cooperation of the lower fixing block 118 and the fixing post 12. The positioning post 7 is fixed in the groove 6 by the cooperation of the side fixing block 113 and the fixing groove 13. After the lower fixing block 118 is separated from the fixing post 12, the side fixing block 113 can be separated from the fixing groove 13 by rotating the rotating rod 111, and the positioning post 7 can be separated from the groove 6.
[0029] A guide cylinder 16 is fixedly connected to the bottom of the disc 1. A hammering post 17 is fitted to the inner wall of the guide cylinder 16.

The upper surface of the limiting post 19 is fixedly connected to the bottom of the hammering post 17. An arc-shaped post 20 is fixedly connected to one end of the hammering post 17.
[0030] It should be noted that multiple hammering posts 17 can be connected together by the arc-shaped post 20, and the movement trajectory of the hammering post 17 can be guided by the guide cylinder 16. Through the cooperation of the limiting post 19 and the second strip hole 18, the hammering post 17 can be prevented from separating from the guide cylinder 16. When the user hammers the arc-shaped post 20, the hammering post 17 can apply an instantaneous impact force to the first arc-shaped plate 2 or the second arc-shaped plate 4 stuck at the bottom of the disc 1, and the instantaneous impact force can loosen the first arc-shaped plate 2 or the second arc-shaped plate 4, thereby making it easier for the user to remove the first arc-shaped plate 2 or the second arc-shaped plate 4 stuck at the bottom of the disc 1.
[0031] The working principle of this invention is as follows: First, the positioning pins 7 on the first arc plate 2 and the second arc plate 4 are inserted into the corresponding grooves 6, and the retaining ring 8 is made to fit against the upper surface of the disc 1. Then, the sliding sleeve 114 on the rotating rod 111 is pushed to make the distance between the lower fixing block 118 and the cylinder 112 reach the minimum value. By rotating the sliding sleeve 114, the side fixing block 113 is inserted into the fixing groove 13. After the side fixing block 113 is inserted into the fixing groove 13, the sliding sleeve 114 is released, and the lower fixing block 118 is made to contact the bottom of the fixing pin 12 by the elastic force of the spring 116. At this time, the side fixing block 113 is fixed in the fixing groove 13 by the lower fixing block 118. By the cooperation of the side fixing block 113 and the fixing groove 13, the first arc plate 2 and the second arc plate 4 are both fixed on the disc 1. At this time, the brush 3 and the steel wool 5 can be fixed on the cleaning device.
[0032] Then, the cleaning device with brush 3 and steel wool 5 is fixed to the sweeper, and the sweeper drives the cleaning device to rotate. At this time, the stains on the ground can be cleaned by the rotating brush 3 and steel wool 5.
[0033] When it is necessary to disassemble the brush 3 on the cleaning device, first push the sliding sleeve 114 on the rotating rod 111 to separate the lower fixing block 118 from the fixing post 12, and then rotate the sliding sleeve 114 to separate the side fixing block 113 from the fixing groove 13. Then, by pushing the first arc plate 2, the brush 3 can be disassembled.
[0034] When it is necessary to remove the steel wool 5 from the cleaning device, first push the sliding sleeve 114 on the rotating rod 111 to separate the lower fixing block 118 from the fixing post 12, and then rotate the sliding sleeve 114 to separate the side fixing block 113 from the fixing groove 13. Then, by pushing the second arc plate 4, the steel wool 5 can be removed.
[0035] The above description is merely a preferred embodiment of the present invention.
