Description

Technical Field

[0001] The utility model relates to the technical field of road marking spraying, and more specifically, particularly relates to a traffic road marking spraying device. Background Art

[0002] Traffic markings refer to signs on the road surface that use lines, arrows, text, elevation marks, raised road signs and contour marks to convey traffic information such as guidance, restrictions and warnings to traffic participants. Its function is to control and guide traffic. It can be used in conjunction with signs or alone. Traffic marking spraying devices are usually used to draw traffic markings on roads. Traditional spraying devices are very simple roller brushes. The drawing of traffic markings usually relies on the experience of staff, or tape is pasted on the edge of the traffic markings on the road, and then painted, which is time-consuming and laborious.

[0003] The utility model patent with announcement number CN219157377U discloses a road marking sprayer, including a base plate, wheels are installed at the four corners of the bottom of the base plate, a support frame is installed at one end of the top of the base plate, a controller is installed on the top sleeve of the support frame, a groove is opened on the edge of the top end of the base plate away from the support frame, a curved rod is rotatably connected to the inner side of the groove, a line drawing cover is installed at one end of the curved rod, and a flat nozzle is installed on the inner top of the line drawing cover. During the spraying process, the operator only needs to push the wheel, look at the line drawing cover in front and align it with the two sides of the original road sign mark to make the sprayed marking line uniform and neat, which effectively solves the problem of time-consuming and labor-intensive traditional use of roller brushes. However, its disadvantage is that the width of the line drawing cover cannot be adjusted, and it still needs to rely on the original road sign mark to be used, so it is not very applicable.
