Painting the guardrails of highways plays an important role in the use of guardrails of highways, such as preventing corrosion and rust, improving aesthetics, increasing wear resistance, and extending the service life of guardrails. Most of the current painting equipment is open, that is, the guardrails are painted in a completely open manner. This painting method will cause part of the paint to fly into the air and scatter into the environment, which will pollute the environment on the one hand and waste paint on the other.

[0035] The use principle of this embodiment is as follows: when in use, according to the height and width of the guardrail board on site, the height of the entire frame and the distance between the entire frame and the support column 12 are adjusted according to the method described above, and the height of the semi-elliptical concave notch composed of notch 16 and notch 2 17, notch 3 20 and notch 4 21 is adjusted, so that the semi-elliptical concave notch can eat the guardrail board into the frame, and almost completely cover the guardrail board at the part to be painted, so as to reduce the amount of paint drifting into the air; according to actual needs, the angle between the nozzle 26 and the corresponding baffle 1 14 and baffle 2 15 is adjusted, and the angle of the nozzle 26 tilting upward or downward can be adjusted. At the same time, the position of the corresponding nozzle 26 at the threaded rod 2 50 or the position at the threaded rod 4 52 can be adjusted by rotating the ring 51. After adjustment, use a car or other driving tool to pull the device forward in the direction of the guardrail, and the baffle 1 14 and baffle 2 15 are located in front of the driving direction. Turn on the air pump 9 and the injection pump 5, The wind force generated by the suction of the air pump 9 on the outer side of the outermost layer of oil-absorbing baffle 31 should be controlled between 0.3-0.5m / s. As the bottom plate 1 moves forward, the semi-elliptical concave notch moves along the length direction of the guardrail plate, and the nozzle 26 sprays paint on the guardrail plate. Due to the weak suction force generated by the air pump 9, the scattered paint will float in the direction of the baffle three 18 and the baffle four 19. The paint is first blocked by the outermost layer of oil-absorbing baffle 31, and the paint moves along the suction. The oil baffle plate 31 flows downward into the paint receiving groove 29, and part of the scattered paint enters the middle layer of the oil absorbing baffle plate 31 through the perforation 33 of the outermost layer of the oil absorbing baffle plate 31, and is partially blocked by the middle layer of the oil absorbing baffle plate 31. The remaining scattered paint enters the innermost layer of the oil absorbing baffle plate 31 through the perforation 33 of the middle layer of the oil absorbing baffle plate 31, and finally the amount of paint entering the inner side of the innermost layer of the oil absorbing baffle plate 31 is very small, so that the service life of the second connecting pipe 36 can be extended; After use, the paint in the oil absorption baffle 31 and the groove 28 can be cleaned out through the window 30; when the device moves forward, the wind generated by the forward movement will form a turbulent wind in the entire frame due to the presence of baffle 1 14, baffle 2 15, baffle 4 19 and baffle 3 18. If there is no suction force of the air pump 9 and the presence of connecting plate 1 24 and connecting plate 2 25, the scattered paint will be scattered, and the recovery rate of the paint by baffle 3 18 and baffle 4 19 will be very low, which will eventually cause most of the scattered paint to enter the external environment. Therefore, the structures related to connecting plate 1 24 and connecting plate 25 and the air pump 9 are set, and the inclined nozzle 26 will increase the recovery efficiency. The wind force outside the oil absorption baffle 31 cannot be too large, otherwise it will affect the painting efficiency.
