Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a spraying device for polyurethane asphalt pavement paving. Background Technology

[0002] During the paving of shallow asphalt pavements, pure water is sprayed onto the surface to induce a reaction, followed by compaction with a paver for better compaction. Spraying pure water forms a thin water film on the asphalt surface, reducing friction between the asphalt and the paver during paving, promoting uniform asphalt distribution, and preventing cracks and deformation. Moisture may improve the fluidity of polyurethane asphalt, making it easier to form a smooth, uniform surface during paving. The water film also reduces asphalt adhesion to rollers or other construction equipment, reducing cleaning work and improving construction efficiency. For some polyurethane asphalts, moisture may accelerate the curing process, allowing the asphalt to reach its design strength and stability more quickly.

[0003] However, existing technologies have the following problems in practical use:

[0004] In the existing technology, when spraying asphalt pavement, the sprayer is carried out manually on the paved asphalt surface. This makes it difficult to spray water evenly on the asphalt pavement. At the same time, it is difficult for workers to control the water flow rate and volume, which makes the operation difficult. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 6 This utility model provides a spraying device for polyurethane asphalt pavement paving. This spraying device is used in the scenario of spraying water to maintain asphalt pavement. In this embodiment, the structure of the spraying device is improved to make it have the advantage of more uniform water spraying.

[0028] Example 1:

[0029] Please see Figures 1 to 6To facilitate the connection of the device with other equipment, the device includes a mounting block 18 fixedly installed on the upper end of the base plate 1, a spray pump 17 fixedly installed on the upper end of the mounting block 18, a flow meter 23 fixedly installed on the upper end of the spray pump 17, a connecting plate 10 for protection fixedly connected to the side of the base plate 1, a connecting sleeve 11 for connection fixedly connected to the side of the connecting plate 10, a fixing bracket 24 for connection fixedly installed on the other side of the base plate 1, a connecting ring 25 for positioning fixedly installed on the other side of the base plate 1, a conveying pipe 15 for flow fixedly installed on one side of the spray pump 17, and a flexible hose 16 for conveying fixedly installed on the other side of the spray pump 17.

[0030] The connecting plate 10 and sleeve 11 can protect the diversion pipe 8. The fixing frame 24 and connecting ring 25 can make it easier for workers to fix the device on the paver and move forward or backward in sync with the paver, further improving the convenience of the device. The conveying pipe 15 and hose 16 can deliver the water in the water tank 4 to the diversion pipe 8 more conveniently and stably for spraying.

[0031] Example 2:

[0032] Please see Figures 1 to 4 To ensure the overall stability of the water bucket 4, a fixed base 2 for positioning is fixedly installed on the upper end of the base plate 1. The water bucket 4 for storage is fixedly installed on the upper end of the fixed base 2. A heating plate 3 is snapped into the upper end of the fixed base 2. A screw 14 for fixing is inserted into the lower end of the fixed base 2. The screw 14 passes through the upper end of the fixed base 2 and is threaded to the upper end of the base plate 1. A bearing 5 for positioning is fixedly installed on the inner bottom wall of the water bucket 4. A rotating shaft 6 for rotation is snapped into the upper end of the bearing 5. A scraper 7 for rotation is fixedly connected to the outer surface of the rotating shaft 6. A retaining ring 12 for positioning is snapped into the outer surface of the rotating shaft 6. A stirring blade 13 for mixing is fixedly connected to the side of the retaining ring 12. A top cover 19 for connection is installed on the upper end of the water bucket 4. A connecting column 20 for support is fixedly installed on the upper end of the top cover 19. A motor 21 is fixedly installed on the upper end of the connecting column 20.

[0033] With the heating plate 3 and screws 14, the fixed base 2 can be more stably fixed to the upper end of the base plate 1, further supporting and limiting the water bucket 4, ensuring the stability of the water bucket 4. With the bearing 5, rotating shaft 6, scraper 7, retaining ring 12, stirring blade 13, top cover 19, connecting column 20 and motor 21, by turning on the motor 21, the rotating shaft 6 can be driven to rotate, and the scraper 7 and stirring blade 13 can be driven to rotate, which can clean the water stains remaining on the inner wall of the water bucket 4. At the same time, when it is necessary to use the device to spray other repair materials, the materials can be fully stirred, further improving the practicality of the device.

[0034] Example 3:

[0035] Please see Figure 4 and Figure 5 In order to reinforce the diversion pipe 8, a diversion pipe 8 for flow is fixedly installed at the lower end of the base plate 1. A spray nozzle 9 for spraying is threadedly connected to the lower end of the diversion pipe 8. A bolt 22 for fixing is inserted into the upper end of the diversion pipe 8. The bolt 22 passes through the upper end of the diversion pipe 8 and is threadedly connected to the lower end of the base plate 1.

[0036] By using bolts 22, the diversion pipe 8 can be more securely fixed to the lower end of the base plate 1, further ensuring that the diversion pipe 8 will not fall off the base plate 1 when the operator moves the device, thus further improving the overall stability of the device.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0038] In this invention, the working steps of the device are as follows:

[0039] First, water is fed into the bucket 4 through the inlet at the top of the top cover 19. Then, the spray pump 17 is started, and the water inside the bucket 4 is transported to the diversion pipe 8 through the delivery pipe 15 and the hose 16. The water is then initially diverted through the diversion pipe 8 and then sprayed evenly onto the asphalt pavement through the nozzle 9. Next, the motor 21 is started, which drives the rotating shaft 6 to rotate, thereby driving the scraper 7 to rotate. Finally, the scraper 7 scrapes the inner wall of the bucket 4 during the mixing process to prevent water stains from remaining, thus facilitating the cleaning of the bucket 4 by the staff.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
