[0036] A movable plate 1 is fixedly connected to a loading tank 2. A stirring rod 3 is rotatably connected inside the loading tank 2. The loading tank 2 is connected to a discharge pipe 4. A first control valve 5 is installed on the discharge pipe 4. The paint is put into the loading tank 2. The stirring rod 3 rotates to stir the paint inside the loading tank 2. The first control valve 5 is opened to allow the paint inside the loading tank 2 to be discharged through the discharge pipe 4.

[0037] The processing box 6 is fixedly connected to the movable plate 1. The movable plate 1 has an inlet 7. The processing box 6 has a collection box 8 inside. The bottom of the collection box 8 has a filter screen 9. The first fan 10 is fixedly connected inside the collection box 8. The first fan 10 works to make the dust on the road enter the collection box 8 through the inlet 7.

[0038] The blower 11 has a first air outlet 12 on the movable plate 1. The first air outlet 12 is connected to the blower 11 and the processing box 6. A heating block 13 is fixedly connected inside the first air outlet 12. When the road is wet, the heating block 13 works to heat the nearby air. The air discharged by the first fan 10 is blown to the road through the blower 11 for drying.

[0039] The bottom of the movable plate 1 is equipped with rollers 14. When marking lines on the road with this device, the movable plate 1 is easy to move on the road because the bottom of the movable plate 1 is equipped with rollers 14.

[0040] A push rod 15 is fixedly connected to the movable plate 1. When marking lines on the road using this device, the worker can manually push the push rod 15 to move the movable plate 1 on the road because the bottom of the movable plate 1 is equipped with rollers 14.

[0041] An L-shaped plate 16 is fixedly connected to the loading tank 2, and a drive motor 17 is fixedly connected to the L-shaped plate 16. The drive shaft of the drive motor 17 is fixedly connected to the stirring rod 3. When the paint is put into the loading tank 2, the drive motor 17 works to make the stirring rod 3 rotate. During the rotation of the stirring rod 3, the paint inside the loading tank 2 is stirred.

[0042] A support plate 18 is fixedly connected inside the processing box 6. The support plate 18 supports the collection box 8. One end of the collection box 8 is located outside the processing box 6. When the collection box 8 is placed inside the processing box 6, it is supported by the support plate 18.

[0043] An annular plate 19 is fixedly connected to the inner wall of the filling barrel 2. A cavity 20 is opened on the annular plate 19. A second air outlet 21 is opened at the bottom of the cavity 20. The cavity 20 is connected to the treatment box 6 through a connecting pipe 22. A second control valve 23 is installed on the connecting pipe 22. When the inner wall of the filling barrel 2 is covered with paint, the operator manually opens the second control valve 23. The first fan 10 works to allow dust on the road to enter the interior of the collection box 8 through the inlet 7. The purified gas enters the interior of the cavity 20 through the connecting pipe 22. The gas inside the cavity 20 is discharged through the second air outlet 21. Since the second air outlet 21 faces downward toward the inner wall of the filling barrel 2, the air discharged from the second air outlet 21 blows the paint attached to the inner wall of the filling barrel 2 downward to the bottom, so that the paint can be discharged through the discharge pipe 4 at the bottom.

[0044] A U-shaped plate 24 is movably connected to the lower part of the movable plate 1. A second fan 25 is fixedly connected to the U-shaped plate 24. After the paint inside the loading tank 2 is stirred evenly, the staff opens the first control valve 5, so that the paint inside the loading tank 2 flows through the discharge pipe 4 to the road for line marking. After the paint is applied to the road surface, the second fan 25 works to dry the paint on the road surface, which can accelerate the drying of the paint.

[0045] A pneumatic telescopic rod 26 is fixedly connected to the movable plate 1. The movable end of the pneumatic telescopic rod 26 is fixedly connected to the U-shaped plate 24. After the paint inside the filling barrel 2 is stirred evenly, the staff opens the first control valve 5, allowing the paint inside the filling barrel 2 to flow through the discharge pipe 4 to the road for line marking. After the paint is applied to the road surface, the staff manually pushes the push rod 15. During the movement of the push rod 15, the movable plate 1 moves, which in turn moves the U-shaped plate 24, positioning it above the road paint. The pneumatic telescopic rod 26 then moves the U-shaped plate 24 downwards, allowing the second fan 25 to approach the paint applied to the road. The second fan 25 then dries the paint on the road surface, thus accelerating the drying process.

[0046] A stirring method for hot-melt reflective coatings, the method comprising the following steps:

[0047] The operation of the first fan 10 causes dust from the road to enter the collection box 8 through the inlet 7;

[0048] The heating block 13 heats the surrounding air, and the air discharged from the first fan 10 is blown to the road through the air pipe 11 for air drying.

[0049] The paint is placed inside the filling tank 2, and the stirring rod 3 rotates to stir the paint inside the filling tank 2. The first control valve 5 is opened to allow the paint inside the filling tank 2 to be discharged to the road through the discharge pipe 4 for marking.

[0050] Working principle: The paint is put into the inside of the loading tank 2, and the drive motor 17 works to make the stirring rod 3 rotate. During the rotation of the stirring rod 3, the paint inside the loading tank 2 is stirred.

[0051] Before the paint is applied to the road surface, the first fan 10 operates to allow dust on the road to enter the collection box 8 through the inlet 7. The first air outlet 12 is fixedly connected to the heating block 13. When the road is wet, the heating block 13 operates to heat the surrounding air. The air discharged by the first fan 10 is blown to the road through the air pipe 11 for drying, which makes it easier to apply paint to the cleaned and dried road surface.

[0052] The staff manually pushes the push rod 15, causing the moving plate 1 to move on the road. The staff opens the first control valve 5, allowing the paint inside the loading tank 2 to flow through the discharge pipe 4 onto the road for marking. After the paint is applied to the road surface, the staff manually pushes the push rod 15, causing the moving plate 1 to move. The moving plate 1 drives the U-shaped plate 24 to move, positioning the U-shaped plate 24 above the road paint. The pneumatic telescopic rod 26 then moves the U-shaped plate 24 downwards, allowing the second fan 25 to approach the paint applied to the road. The second fan 25 then dries the paint on the road surface, thus accelerating the drying process.

[0053] Example 2

[0054] The following technical features are added based on Embodiment 1:

[0055] A mixing device for hot-melt reflective coating has an L-shaped plate 16 with a receiving cavity 27 and an air inlet 28 facing a drive motor 17. The receiving cavity 27 is connected to a second fan 25 via a hose 29. Since the drive motor 17 will generate heat during operation, the second fan 25 blows the heat near the drive motor 17 through the air inlet 28, the receiving cavity 27, and the hose 29 to the coating on the road surface, accelerating the drying of the road surface coating.

[0056] Working principle: The paint is put into the inside of the loading tank 2, and the drive motor 17 works to make the stirring rod 3 rotate. During the rotation of the stirring rod 3, the paint inside the loading tank 2 is stirred.

[0057] Before the paint is applied to the road surface, the first fan 10 operates to allow dust on the road to enter the collection box 8 through the inlet 7. The first air outlet 12 is fixedly connected to the heating block 13. When the road is wet, the heating block 13 operates to heat the surrounding air. The air discharged by the first fan 10 is blown to the road through the air pipe 11 for drying, which makes it easier to apply paint to the cleaned and dried road surface.

[0058] The staff manually pushes the push rod 15, causing the moving plate 1 to move on the road. The staff opens the first control valve 5, allowing the paint inside the loading tank 2 to flow through the discharge pipe 4 onto the road for marking. After the paint is applied to the road surface, the staff manually pushes the push rod 15, causing the moving plate 1 to move. The moving plate 1 drives the U-shaped plate 24 to move, positioning the U-shaped plate 24 above the road paint. The pneumatic telescopic rod 26 then moves the U-shaped plate 24 downwards, allowing the second fan 25 to approach the paint applied to the road. The second fan 25 then dries the paint on the road surface, thus accelerating the drying process.

[0059] Since the drive motor 17 will generate heat during operation, the second fan 25 will work to blow the heat near the drive motor 17 through the air inlet 28, the receiving cavity 27, and the hose 29 to the paint applied to the road surface, thereby accelerating the drying of the road surface paint.
