Specific embodiments

[0022] Figures 1-6 is the best embodiment of the road working vehicle with a spraying function. The following will further explain the present utility model in conjunction with the attached Figures 1-6 drawings.

[0023] Referring to Figures 1-2 , the road working vehicle with a spraying function includes a working vehicle body 1, a chassis 2, a first road surface working mechanism 3 and a second road surface working mechanism 4. The working vehicle body 1 is rotatably arranged on the upper side of the chassis 2 through a rotating disc 7. The first road surface working mechanism 3 is arranged on the front side of the working vehicle body 1, and the second road surface working mechanism 4 is fixed on the rear side of the chassis 2. A water tank 14 is provided on the working vehicle body 1.

[0024] In this embodiment, the first road surface working mechanism 3 is a cleaning device. The cleaning device is fixed on the front side of the working vehicle body 1 through a hydraulic swing arm 5. The second road surface working mechanism 4 is a milling machine. A milling installation seat 6 is fixed on the rear side of the chassis 2, and the milling machine is slidably arranged on the milling installation seat 6. During road construction, the milling machine excavates the road surface to be repaired into a square groove, then the cleaning device cleans the gravel in the groove, and finally the repair material is filled into the groove to complete the repair of the road surface. A large amount of dust will be generated during milling and cleaning operations. Therefore, a spray structure needs to be designed for dust suppression.

[0025] See Figures 3-4, in this embodiment, the first road surface working mechanism 3 includes a cleaning fixed box body 301, a cleaning swing seat 302 and a cleaning brush 304. The cleaning swing seat 302 is rotatably connected to the opening side of the cleaning fixed box body 301. A swing oil cylinder 303 is connected between the cleaning fixed box body 301 and the cleaning swing seat 302. The cleaning brush 304 is rotatably arranged inside the cleaning swing seat 302. When cleaning is required, first, the cleaning swing seat 302 and the cleaning brush 304 are lifted by the swing oil cylinder 303, and the crushed stones in the groove are scraped out by the cleaning fixed box body 301. In this way, the workload of the cleaning brush 304 can be effectively reduced, the work efficiency can be improved, and the wear of the cleaning brush 304 can be reduced. Then, the swing oil cylinder 303 swings the cleaning swing seat 302 and the cleaning brush 304 back to the opening side of the cleaning fixed box body 301, and the cleaning brush 304 works to sweep the crushed stones into the cleaning fixed box body 301.

[0026] A horizontally arranged first spray pipe 8 is fixed on the upper side of the front end of the cleaning swing seat 302. The first spray pipe 8 is connected to the water tank 14 through a water supply pipe. A number of cleaning spray nozzles are arranged on the first spray pipe 8. When the cleaning brush 304 works, the working surface is sprayed with dust suppression through the cleaning spray nozzles on the first spray tank, so as to improve the working environment, reduce environmental pollution, and ensure the normal driving of other surrounding vehicles.

[0027] See Figure 5 , inside the end of the milling machine far from the working vehicle body 1, a second spray pipe 10 is provided. A plurality of milling spray nozzles 11 are provided on the lower side of the second spray pipe 10. The dust generated during the operation of the milling machine is directly suppressed by the second spray pipe 10 inside the milling machine.

[0028] See Figure 6 , in this embodiment, the rotating disk 7 includes a fixed seat 702 and a rotating seat 701. The rotating seat 701 is fixed on the lower side of the working vehicle body 1. The fixed seat 702 is fixed on the chassis 2. The rotating seat 701 is rotatably connected to the fixed seat 702. A water supply slip ring structure is provided between the rotating seat 701 and the fixed seat 702. The water supply slip ring structure communicates with the water tank 14 and is connected to the second spray pipe 10 through a water supply pipe. A thrust bearing 704 is provided between the lower side of the rotating seat 701 and the fixed seat 702. In order to ensure the seal between the rotating seat 701 and the fixed seat 702, a sealing ring 703 is also provided between the upper side of the fixed seat 702 and the rotating seat 701.

[0029] Specifically, the water supply slip ring structure includes a first water supply flow channel 12 and a second water supply flow channel 13. The first water supply flow channel 12 is opened inside the rotating seat 701. The second water supply flow channel 13 is opened on the fixed seat 702. The second water supply flow channel 13 is annular. The inlet of the first water supply flow channel 12 communicates with the water tank 14. The outlet of the first water supply flow channel 12 communicates with the second water supply flow channel 13. The second water supply flow channel 13 is connected to the second spray pipe 10 through a water supply pipe.

[0030] Working process: The road surface to be repaired is excavated into a rectangular groove by a milling machine, and then the working vehicle body 1 is rotated 180 degrees by the rotating disk 7, and the cleaning device is rotated to the same side of the milling machine. Secondary milling may be carried out after cleaning. During the rotation of the rotating disk 7, the first water supply channel 12 and the second water supply channel 13 are always connected to ensure the normal operation of the second spray pipe 10. The cleaning device is used to clean the gravel in the groove, and finally the repair material is filled into the groove to complete the repair of the road surface. A large amount of dust is generated during the milling operation and the cleaning operation. The first spray pipe 8 and the second spray pipe 10 are used to spray and suppress the dust generated during the operation of the first road surface working mechanism 3 and the second road surface working mechanism 4 respectively.

[0031] In other embodiments, the first road surface working mechanism 3 and the second road surface working mechanism 4 may also be other road surface working equipment.
