[0028] See also Figure 1-7 The present invention provides an embodiment of a road marking spraying device, comprising a frame, on which is mounted an equipment box 1 and a material storage tank 2, a frame base 3, and handrails 4. A control panel 27 is mounted between the handrails 4 and operates via an electrical signal control device. The equipment box 1 and the material storage tank 2 are fixedly mounted on the base 3. A chute 31 is defined on the sidewall of the base 3, within which a slider is disposed, and a spraying mechanism is fixedly connected. The position of the spraying mechanism can be easily adjusted by moving the slider along the chute 31.

[0029] The spray mechanism includes a first fixed plate 5 and a second fixed plate 6. An electric telescopic rod 17 is installed between the first fixed plate 5 and the slider, which controls the position and distance of the spray mechanism.

[0030] The limiting mechanism includes a connecting rod 9, which is rotatably mounted on the inner wall of the machine box 7. Two ends of the connecting rod 9 are respectively provided with two threaded sections in opposite directions. Two limiting plates 10 are sleeved on the connecting rod 9. The two limiting plates 10 are respectively located at the two threaded sections. The top of the limiting plate 10 is slidingly connected to the top of the machine box 7. A forward and reverse motor 11 is installed on the second fixed plate 6. The output shaft of the forward and reverse motor 11 passes through the second fixed plate 6 and is coaxially connected to the connecting rod 9.

[0031] A discharge barrel 12 is installed on the top of the machine box 7. The discharge barrel 12 is connected to the nozzle 8. A feeding pipe 13 is connected between the discharge barrel 12 and the storage tank 2. A first stirring mechanism is provided in the discharge barrel 12. The first stirring mechanism is used to evenly stir the paint in the discharge barrel 12.

[0032] The first stirring mechanism includes a first rotating shaft 14, which is rotatably connected to the inner side wall of the discharge barrel 12. A plurality of stirring rods 15 are evenly spaced on the first rotating shaft 14, and the first rotating shaft 14 is connected to a driving mechanism. The driving mechanism includes a connecting shaft, which is coaxially connected to the first rotating shaft 14. The other end of the connecting shaft extends through the discharge barrel 12 and is coaxially mounted with a first belt pulley 16. A second belt pulley 26 is coaxially mounted on the output shaft of the forward and reverse motor 11. The first belt pulley 16 is connected to the second belt pulley 26 by the first belt 16.

[0033] The first belt 16 enables the forward and reverse motor 11 to simultaneously drive the first rotating shaft 14 to move during operation, thereby stirring the paint in the discharge barrel 12 evenly, making the paint sprayed from the nozzle 8 more uniform, and ensuring the quality of the spraying and marking.

[0034] Four rollers 18 are mounted on the outer bottom of the base 3, and are located near the four corners of the base 3. A second stirring mechanism is provided within the storage tank 2. The second stirring mechanism includes a second rotating shaft 19, which is rotatably mounted on the inner bottom of the storage tank 2. A plurality of circular tubes 20 are evenly connected to the second rotating shaft 19 at equal intervals.

The worm 25 is meshed with the worm gear 24. A second belt 26 is connected to the worm 25 and the shaft.

[0036] When the roller 18 on the frame is moving, the second rotating shaft 19 in the storage tank 2 is rotated through the linkage of the rotating rod 22, the worm gear 24, the worm 25 and other structures, so as to achieve the effect of evenly stirring the paint in the storage tank 2.

A scraper 30 is installed at the end of the support rod 28 outside the circular tube 20. By adjusting the centrifugal force applied to the support rod 28, the scraper 30 can be brought into contact with the inner wall of the storage tank 2, thereby facilitating the cleaning of residual paint in the storage tank 2.

[0038] Specific implementation: When performing road marking construction, the paint in the storage tank 2 enters the discharge barrel 12 through the feeding pipe 13, then enters the nozzle 8 through the discharge barrel 12, and finally is sprayed out through the nozzle 8 to complete the road marking construction.

[0039] During the marking construction process, the forward and reverse motor 11 is provided to drive the connecting rod 9 to rotate. During the rotation of the connecting rod 9, the limit plate 10 connected thereto will move toward or in the opposite direction. The position distance between the two limit plates 10 can be adjusted to facilitate shielding the sprayed paint and avoid the problem of paint scattering everywhere.

[0040] A discharge barrel 12 is provided on the top of the nozzle 8, and the paint to be sprayed is first discharged into the discharge barrel 12. The first belt 16 makes the forward and reverse motor 11 rotate, thereby synchronously driving the first rotating shaft 14 to move, and the stirring rod 15 on the rotating shaft can promptly and evenly stir the paint to be sprayed, thereby ensuring the quality of the spraying.

[0041] At the same time, a second stirring mechanism is provided in the storage tank 2. Through the rotation of the roller 18, the worm gear 24 on the rotating rod 22 drives the worm 25 to rotate, and the worm 25 drives the second gear 23 and the first gear 21 to rotate through the second belt 26, thereby realizing the rotation of the second rotating shaft 19 in the storage tank 2, and realizing uniform stirring of the paint in the storage tank 2.

[0042] By controlling the rotation speed of the roller 18, the centrifugal force exerted on the support rod 28 in the circular tube 20 is varied, thereby controlling the distance at which the support rod 28 slides out of the circular tube 20, so that the scraper 30 contacts the inner wall of the storage tank 2. After the paint in the storage tank 2 is used up, the paint on the inner wall of the storage tank 2 can be scraped out and cleaned, which is highly practical.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
