Description

Technical Field

[0001] This utility model relates to the field of asphalt spraying technology, and more specifically, to an emulsified asphalt spraying device. Background Technology

[0002] my country is a vast country with numerous highways of various grades. The most common damage to highways is potholes and cracks. Once these appear, road maintenance personnel need to repair them quickly. During the repair process, asphalt spraying equipment is often used to spray asphalt to fill the damaged road surface.

[0003] A search revealed that Chinese utility model patent application number CN202120667853.6 discloses an emulsified asphalt spraying device, including a support frame, an installation plate in the middle of the support frame, a heating mixing tank on the installation plate, a transmission rod inside the heating mixing tank, multiple stirring blades on the transmission rod, a heating plate fixedly connected to one side of the inner wall of the heating mixing tank by bolts, a heater mounted on the installation plate, a booster pump mounted on the installation plate and located on one side of the heater, a booster pipe sealed to the output end of the booster pump, the other end of the booster pipe extending into the heating mixing tank and sealed thereto, an emulsifier storage tank at the bottom of the installation plate, and the emulsifier storage tank sealed to the heating mixing tank via a pipe, and multiple nozzles at the bottom of the heating mixing tank.

[0004] When filling damaged roads with asphalt, emulsified asphalt is sprayed out through nozzles supported by a spray pump. However, because the nozzles are located directly below the mounting plate and other structures, it is difficult to observe their position and align them with the damaged road surface. This results in emulsified asphalt being sprayed onto good surfaces, affecting spraying accuracy and causing waste. Furthermore, because the damaged road surface is irregular, the nozzle position needs constant lateral adjustment during spraying. This requires adjusting the entire equipment, making nozzle lateral adjustment difficult and reducing its practicality. Utility Model Content

[0030] Please see Figures 1-5The emulsified asphalt spraying device includes a vehicle body 1, a spray pump 2, and a heated mixing tank 3. The heated mixing tank 3 is mounted on the vehicle body 1. A connecting pipe 4 is connected to the bottom of the heated mixing tank 3, and the bottom end of the connecting pipe 4 extends to the bottom of the vehicle body 1. A valve 5 is installed on the connecting pipe 4. A second rotating shaft 23 is fixedly connected to the rotating rod of the valve 5. A handle 24 is fixedly connected to the side end of the second rotating shaft 23 to facilitate operation of the valve 5. A sealing plate 6 is fixedly connected to the outer side of the bottom end of the connecting pipe 4 to seal the area. A guide hopper 7 is slidably mounted on the bottom end of the sealing plate 6. A second insulation sleeve 21 is fitted over the guide hopper 7. Two L-shaped strips 8 are fixedly connected to the top end of the guide hopper 7, and a groove 9 is formed between the two L-shaped strips 8 and the guide hopper 7. The sealing plate 6 slides in cooperation with the two grooves 9. An adjusting plate 10 is fixedly connected to the top end of the two L-shaped strips 8, and a screw 11 is threaded onto the adjusting plate 10. A mounting plate 12 is fixedly connected to the side end of the vehicle body 1, and a first motor 13 is mounted on the mounting plate 12. The output end of 13 is fixedly connected to the side end of screw 11. The side end of screw 11 is fixedly connected to limit plate 22, which limits the adjustment plate 10. The bottom end of guide hopper 7 is connected to a conveying mechanism. The end of the conveying mechanism extending to the outside of the vehicle body 1 is connected to a heat preservation box 14. The conveying mechanism includes a conveying pipe 16. The outside of the conveying pipe 16 is covered with a first heat preservation sleeve 20. The conveying pipe 16 is connected to guide hopper 7. A second motor 17 is installed on the side end of the conveying pipe 16. The output of the second motor 17 is... The first rotating shaft 18 is fixedly connected to the inside of the conveying pipe 16. The spiral blade 19 is fixedly connected to the outside of the first rotating shaft 18. The first rotating shaft 18 and the spiral blade 19 are driven to rotate by the second motor 17. The spiral blade 19 rotates to transport the emulsified asphalt falling into the conveying pipe 16 to the inside of the insulation box 14. The spray pump 2 is installed at the bottom of the insulation box 14. The input end of the spray pump 2 is connected to the inside of the insulation box 14. The output end of the spray pump 2 is equipped with a nozzle 15.

[0031] Specifically, by setting up the guide hopper 7 and conveying mechanism, the nozzle 15 is positioned on one side of the vehicle body 1. This facilitates observation of the nozzle 15's position when spraying emulsified asphalt on damaged road surfaces, ensuring easy contact between the nozzle 15 and the damaged road surface, and accurately spraying the emulsified asphalt onto the damaged surface. This improves the accuracy of emulsified asphalt spraying and avoids waste. The first motor 13 drives the screw 11 to rotate, which in turn moves the adjusting plate 10. The adjusting plate 10 then drives the two L-shaped bars 8, the guide hopper 7, and the conveyor. The structure, spray pump 2, and nozzle 15 can move laterally, avoiding the need to adjust the entire device when adjusting the lateral position of nozzle 15. This reduces the difficulty of adjusting the lateral position of nozzle 15 and improves its practicality. The material guide hopper 7 is covered with a second insulation sleeve 21, and the material conveying pipe 16 is covered with a first insulation sleeve 20. At the same time, the first insulation sleeve 20, the second insulation sleeve 21, and the insulation box 14 provide insulation for the emulsified asphalt, which can effectively prevent the emulsified asphalt from solidifying due to low temperature.

[0032] Please see Figure 5 A tank cover 25 is fixedly connected to the top of the heating mixing tank 3. A feeding pipe 29 is connected to the tank cover 25 to facilitate the addition of emulsified asphalt raw materials into the heating mixing tank 3. A third motor 26 is installed on the tank cover 25. A third rotating shaft 27 is fixedly connected to the output end of the third motor 26. Multiple stirring plates 28 are fixedly connected to the outer wall of the third rotating shaft 27.

[0033] Specifically, the third motor 26 drives the third rotating shaft 27 and multiple mixing plates 28 to rotate. The multiple mixing plates 28 stir the emulsified asphalt inside the heated mixing tank 3, which facilitates the uniform mixing of the emulsified asphalt and the uniform heating of the emulsified asphalt by the heating structure inside the heated mixing tank 3.

[0034] In summary, when using the overall equipment:

[0035] Emulsified asphalt raw materials are added into the heated mixing tank 3 through the feeding port. The third motor 26 drives the third rotating shaft 27 and multiple stirring plates 28 to rotate, and the multiple stirring plates 28 stir the emulsified asphalt inside the heated mixing tank 3. The heating structure inside the heated mixing tank 3 heats the emulsified asphalt evenly. After the emulsified asphalt is prepared, the vehicle body 1 is moved to the side of the damaged road surface, and the nozzle 15 is positioned above the damaged road surface. Then, the second rotating shaft 23 is rotated to control the opening and closing of the valve 5, adjusting the flow rate of emulsified asphalt into the guide hopper 7. The emulsified asphalt falling into the guide hopper 7 flows into the conveying pipe 16, and the second motor 17 drives the first rotating shaft 18 and the spiral blade 19 to rotate. The system is activated by rotating the spiral blades 19, which transport the emulsified asphalt falling into the conveying pipe 16 to the interior of the insulation box 14. Simultaneously, the spray pump 2 transports the emulsified asphalt inside the insulation box 14 to the interior of the nozzle 15. The emulsified asphalt is then sprayed onto the damaged road surface through the nozzle 15. When the position of the nozzle 15 needs to be moved laterally, the first motor 13 drives the screw 11 to rotate. The rotation of the screw 11 causes the adjusting plate 10 to move. The adjusting plate 10 drives the two L-shaped bars 8, the guide hopper 7, the conveying mechanism, the spray pump 2, and the nozzle 15 to move laterally, thereby adjusting the lateral position of the nozzle 15 according to the curvature of the damaged road surface. This also facilitates the spraying of emulsified asphalt onto the wider damaged road surface.
