At the bottom of the chassis 3, a threaded elastic tube 13 is provided. At the bottom of the threaded elastic tube 13, a dust suction disc 1 is provided. At both ends of the side of the top of the chassis 3 close to the water tank 6, mounting plates 12 are installed. One end of the mounting plate 12 is movably hinged to a connecting block 10 through a hinge. At equal intervals at the bottom of the connecting block 10, a plurality of spray heads 11 are connected. One end of the connecting block 10 is connected to a water pipe 7. At the top of the connecting block 10, an adjusting structure is provided;

[0020] One end of the water pipe 7 penetrates through one side of the water tank 6 and is communicated with the water tank 6. The water tank 6 is communicated with the connecting block 10 through the water pipe 7. One end of the threaded elastic tube 13 penetrates through the bottom of the chassis 3 and is communicated with the dustbin 5. The dustbin 5 is communicated with the dust suction disc 1 through the threaded elastic tube 13;

[0021] Please refer to Figures 1-4 , a low-noise safe road sweeper further includes an adjusting structure. The adjusting structure further includes a mounting block 8. The mounting block 8 is installed at both ends of the side of the bottom of the chassis 3 close to the water tank 6. Inside the mounting block 8, at one end close to the mounting plate 12, a pneumatic telescopic cylinder 16 is installed. One end of the pneumatic telescopic cylinder 16 is connected to a connecting block 15. At the bottom of the connecting block 15, a movable rod 9 is hinged through a hinge;

[0022] One end of the movable rod 9 penetrates through the bottom end inside the mounting block 8 and is hinged to one end of the top of the connecting block 10 through a hinge. The movable rod 9 and the mounting plate 12 are respectively arranged at both ends of the connecting block 10;

[0023] Specifically, as Figure 1 and Figure 2As shown in the figure, in this device, water inside the water tank 6 is transferred to the inside of the connecting block 10 through the water pipe 7, and the water is sprayed out by using the spray head 11, so as to realize watering the road surface. In order to prevent affecting pedestrians on the roadside during the watering process, when there are pedestrians on the roadside, the user can control the pneumatic telescopic cylinder 16 to expand and contract. Under the expansion and contraction of the pneumatic telescopic cylinder 16, the movable rod 9 can be driven to move, so that the connecting block 10 can rotate as a whole around the mounting plate 12, thereby adjusting the output direction of the spray head 11, so as to avoid affecting pedestrians on the roadside and improve the practicability of this device.

[0024] Embodiment 2: A lifting structure is provided at the top of the suction cup 1. The lifting structure further includes a fixing plate 19. The fixing plate 19 is installed at the bottom end of the chassis 3, and a plurality of servo motors 20 are installed at one end of the fixing plate 19. The output end of the servo motor 20 penetrates through one end of the fixing plate 19 and is connected to a bidirectional threaded rod 14. Two threaded blocks 18 are sleeved on the outer side of the bidirectional threaded rod 14. A cross bar 17 is installed at one end of the threaded block 18, and one end of the threaded block 18 is hinged to the connecting rod 2 through a hinge. One end of the connecting rod 2 is hinged to the top of the suction cup 1 through a hinge;
