[0002] Engineering facilities for the passage of various vehicles and pedestrians are classified according to their usage characteristics into highways, urban roads, rural roads, factory and mining roads, forestry roads, examination roads, competition roads, automobile testing roads, workshop passages, and school roads, etc. They bear the vehicle load transmitted from the road surface and are constructed of materials such as earth and stone. They directly bear the action of vehicles and pedestrians and should have sufficient strength, stability, smoothness, and anti-skid properties. Depending on the materials, they can be divided into asphalt pavement, cement concrete pavement, and gravel pavement, etc.

[0003] In the early days, spraying of municipal roads and bridges often relied on manual labor, with workers using handheld spray guns. This method was extremely labor-intensive, requiring workers to be exposed to the outdoors for extended periods, especially in high temperatures, cold weather, or other harsh conditions. The working environment was harsh, and manual spraying was very inefficient. For large-scale municipal road and bridge networks, it was difficult to complete the comprehensive spraying task in a short time. Furthermore, the uniformity of manual operation was difficult to guarantee, often resulting in some areas being over-sprayed while others were under-sprayed, affecting the maintenance effect. Therefore, a municipal road and bridge spraying device was proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a municipal road and bridge spraying device, which aims to improve the existing technology where large-scale municipal road and bridge networks are difficult to complete the comprehensive spraying task in a short time, and the uniformity of manual operation is difficult to guarantee, which easily leads to some areas being sprayed too much and some areas being sprayed too little, thus affecting the maintenance effect.

First, water and disinfectant can be poured into the water tank 2, and then the water and disinfectant can be mixed by the mixing assembly 7. After the water and disinfectant are mixed, the road and bridge can be sprayed by the spraying assembly 6.

[0029] Reference Figure 1-3 The spraying assembly 6 includes a hollow disc 61. A nozzle 62 is connected to the bottom of the hollow disc 61, and a connecting pipe 63 is connected to the top of the hollow disc 61. The top of the connecting pipe 63 extends to the top of the base plate 1. A rotary sealing joint 64 is fixedly installed on the top of the connecting pipe 63. A water pump 65 is fixedly installed on the top of the base plate 1. One end of the water pump 65 extends into the water tank 2, and the other end connects to the top of the rotary sealing joint 64. Through the cooperation of the hollow disc 61, nozzle 62, connecting pipe 63, rotary sealing joint 64, and water pump 65, when it is necessary to spray disinfectant on roads and bridges, water and disinfectant can first be added to the water tank 2. Then, the water pump 65 can be started to draw water from the water tank 2. The water in the water tank 2 will enter the rotary sealing joint 64, and the water in the rotary sealing joint 64 will enter the hollow disc 61. The water in the hollow disc 61 will be sprayed onto the ground through the nozzle 62. The top of the base plate 1 is fixedly installed. A first motor 66 is installed, and a worm gear 67 is fixedly installed at the output end of the first motor 66. A worm wheel 68 is fixedly installed on the surface of the connecting pipe 63. The worm wheel 68 and the worm gear 67 mesh. A rectangular block 69 is rotatably installed on the back of the worm gear 67. The bottom of the rectangular block 69 is fixedly installed on the top of the base plate 1. Through the cooperation of the first motor 66, the worm gear 67, the worm wheel 68 and the rectangular block 69, when it is necessary to spray the road and bridge, the first motor 66 can be started first. The output end of the first motor 66 drives the worm gear 67 to rotate. The rotation of the worm gear 67 drives the worm wheel 68 to rotate. The rotation of the worm wheel 68 drives the connecting pipe 63, the hollow disc 61 and the nozzle 62 to rotate, thereby spraying the road and bridge. Two sets of cleaning brushes 75 are fixedly installed at the bottom of the base plate 1. The cleaning brushes 75 are located on the left side of the hollow disc 61. By setting the cleaning brushes 75, after the road and bridge are sprayed with water, the cleaning brushes 75 can also clean the stones and other objects on the road and bridge.

[0030] Reference Figure 1-3The mixing component 7 includes a stirring rod 71, the top of which extends through and communicates with the top of the water tank 2. A second motor 72 is fixedly installed on the top of the water tank 2, with its output end fixedly installed on the top of the stirring rod 71. The bottom of the stirring rod 71 is rotatably installed on the bottom of the inner wall of the water tank 2. A stirring blade 73 is fixedly installed on the surface of the second motor 72. Through the cooperation of the stirring rod 71, the second motor 72, and the stirring blade 73, when it is necessary to mix the water and disinfectant inside the water tank 2, the second motor 72 can be started. The output end of the second motor 72 drives the stirring rod 71 to rotate, which in turn drives the stirring blade 73 to rotate. The rotation of the stirring blade 73 can adjust the water and disinfectant in the water tank 2. The internal water and disinfectant are mixed to disinfect roads and bridges. U-shaped brushes 74 are fixedly installed on the top and bottom of the mixing rod 71. The two sets of U-shaped brushes 74 are arranged in opposite directions. When the mixing rod 71 rotates, it can drive the U-shaped brushes 74 to rotate. Since the two sets of mixing rods 71 ​​are arranged in opposite directions, the water and disinfectant inside the water tank 2 can be quickly mixed. A pull ring 8 is provided on the left side of the base plate 1. The right end of the pull ring 8 is threaded to the left side of the base plate 1. The pull ring 8 can limit the rope or other connecting object to the pull ring 8. At this time, the base plate 1 can be moved by pulling the external transport vehicle, so as to spray water and clean the roads and bridges.

[0031] Working principle: When it is necessary to spray disinfectant on roads and bridges, water and disinfectant can first be added to water tank 2. Then, the second motor 72 can be started. The output end of the second motor 72 drives the stirring rod 71 to rotate. The rotation of the stirring rod 71 drives the stirring blade 73 and U-shaped brush 74 to rotate. The rotation of the stirring blade 73 and U-shaped brush 74 can mix the water and disinfectant inside. Then, the water pump 65 can be started to draw water from the water tank 2. The water in the water tank 2 will enter the rotary sealing joint 64. The water will enter the hollow disc 61, and the water inside the hollow disc 61 will be sprayed onto the ground through the nozzle 62. In order to prevent uneven spraying in some areas of the bottom of the base plate 1, the first motor 66 can be started. The output end of the first motor 66 drives the worm gear 67 to rotate, the worm gear 67 rotates, and the worm wheel 68 rotates, which in turn drives the connecting pipe 63, the hollow disc 61 and the nozzle 62 to rotate, thereby spraying the road and bridge. When the base plate 1 moves, it will drive the cleaning brush 75 to move, thereby cleaning stones and other debris on the road and bridge.
