The number of water outlet holes 261 is 3 or 4, and the plurality of water outlet holes 261 corresponds to the positions of the plurality of water outlet rods 23 that are adjacent to each other in sequence. The positions of the water outlet holes 261 need to correspond to the positions of the water outlet rods 23 to ensure that water can be discharged normally. However, the number of water outlet holes 261 needs to be determined according to the target water sweeping range, that is, 4 water outlet holes 261 are used if a larger water sweeping range is required, and 3 water outlet holes 261 are used if a smaller water sweeping range is required. Figure 5 As shown, in this embodiment, the number of the water outlet holes 261 is 4. A mounting plate 11 is fixedly provided on one side of the frame 1, and a mounting hole is provided on the mounting plate 11.

A driven pulley 34 is fixedly provided at a position corresponding to the driving pulley 33 on the outside of the first rotating body 25. The driven pulley 34 is connected to the driving pulley 33 by a belt 35. Among them, a bearing 13 is fixedly arranged between the second cavity 311 and the output shaft 321. The bearing 13 can be a deep groove ball bearing. The bearing 13 ensures the stability of the output shaft 321 when it is working. There are two bearings 13 and they are vertically distributed up and down, a bushing 14 is installed between the two bearings 13, and an oil injection hole 17 is provided on the side of the mounting seat 31 between the two bearings 13. Lubricating oil can be injected into the second cavity 311 through the oil injection hole 17 to prevent the bearing 13 from wearing too quickly and extend the service life of the bearing 13. A hole retaining ring 15 is fixedly provided at the end of the second cavity 311 close to the motor 32, and an oil seal 16 and a hole retaining ring 15 are fixedly provided at the end of the second cavity 311 away from the motor 32.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, on the basis of the above embodiment, a belt tensioning mechanism 4 is further provided between the frame 1 and the mounting seat 31. The belt tensioning mechanism 4 includes a locking bolt 42, and a waist groove 41 is processed on the mounting seat 31. There are multiple waist grooves 41 and they are located at the corners of the mounting seat 31. The locking bolt 42 is threadedly installed at the position corresponding to the waist groove 41 on the frame 1, and the locking bolt 42 crosses the waist groove 41. The frame 1 is provided with a slide groove 18, and the mounting seat 31 is located in the slide groove 18. By rotating the locking bolt 42, the mounting seat 31 and the frame 1 can be locked and fixed and freely slided. A fixing block 44 is fixedly provided on the top of the frame 1, and an adjusting screw 43 is threadedly provided on the fixing block 44. A threaded hole is provided at the position corresponding to the adjusting screw 43 of the mounting seat 31, and the adjusting screw 43 is threadedly connected with the threaded hole. The adjusting screw 43 has a further locking effect on the mounting seat 31, so that the stability of the mounting seat 31 when fixed is better.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, on the basis of the above embodiment, further, a protective cover 5 is fixedly arranged at the bottom of the frame 1, and the protective cover 5 covers the nozzle 24. The protective cover 5 has the function of protecting the nozzle 24 and preventing the nozzle 24 from being damaged by collision. A notch 51 is arranged on one side of the protective cover 5, and the position of the notch 51 belongs to the water spraying range of the nozzle 24, that is, the water sweeping range of the water sweeping mechanism 2. The angle value of the water sweeping range of the water sweeping mechanism 2 is 120 to 160 degrees at any angle within the range of 360 degrees. Since the number of water outlet holes 261 is less than the number of water outlet rods 23, during the rotation of the second rotating body 22, only the water outlet rod 23 connected to the water outlet hole 261 can enter water each time, while the cylinder 26 and the water inlet rod 21 are fixed and do not rotate. As long as the position of the water outlet hole 261 on the cylinder 26 corresponds to the position of the notch 51 of the protective cover 5, the nozzle 24 that rotates to the notch 51 position can spray water each time, and the nozzles 24 at other positions are in a waterless state, achieving the effect of directional washing and sweeping.

[0035] like Figures 1 to 6 As shown, when working, the water inlet rod 21 is first connected to the water tank on the washing and sweeping vehicle through a water pipe, and the water in the water tank enters the interior of the cylinder 26 through the water pipe and the water inlet rod 21 in turn, and then enters the water outlet rod 23 corresponding to the position of the water outlet hole 261 through the water outlet hole 261 on the side of the cylinder 26, and finally the water in the water outlet rod 23 is sprayed onto the road surface through the nozzle 24 to wash the road surface; at the same time, the power supply of the motor 32 is turned on, the motor 32 drives the active pulley 33 to rotate, the active pulley 33 drives the driven pulley 34 to rotate through the belt 35, the driven pulley 34 drives the first rotating body 25 and the second rotating body 22 to rotate, and the second rotating body 22 drives the nozzle 24 to rotate. Due to the action of centrifugal force, the flushing force of the nozzle 24 on the road surface can be increased; sewage and garbage are sucked into the sewage tank through the suction cup on the washing and sweeping vehicle.

[0036] By collecting daily data, we know that the existing brushes need to be replaced once a week at the shortest, and only need to be replaced after two weeks of work at the longest, resulting in high cost of use. However, the components on the water sweeping mechanism of the utility model do not need to be replaced frequently, which reduces the cost of use and improves work efficiency.

[0037] The above are only preferred embodiments of the present invention, and do not limit the scope of the present invention. A person skilled in the art should understand that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principles and purposes of the present invention, which should all be included in the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims and their equivalents.
