Description

Technical Field

[0001] The invention relates to the technical field of road marking construction equipment, and in particular to an integrated intelligent spraying device for road marking construction. Background Art

[0002] Road markings refer to information signs such as lines, arrows, text, facade markings, raised road signs and contour signs on the road surface. They play an important role in the road traffic system. Traffic accidents are prone to occur at night, so the reflective performance of road markings is extremely important for road driving safety. Surface spreading of glass beads is an important way to reflect road markings, and plays a very important role in giving full play to road functions and preventing and reducing the occurrence of traffic accidents.

[0003] At present, the glass bead spreading device of the road marking machine is used to add the glass beads to be used into the hopper. Since the hopper is provided with a particle partition, glass beads of various particle sizes can be placed in the hopper. The glass beads of various specifications are evenly stirred in the mixing box, and the paint is sprayed on the road surface through the paint spraying assembly in front of the glass bead spreading assembly. The glass beads are immediately spread on the wet paint through the glass bead spreading assembly, so that the glass beads adhere to the paint. The device cannot adjust the width and thickness of the paint spraying, and cannot use glass beads of different particle sizes for spreading according to the width and thickness of the paint, which easily leads to the presence of large-particle glass beads in the shallow marking area, so that the large-particle glass beads cannot effectively adhere to the paint, resulting in the loss of glass beads and waste of resources. And for the marking area where the glass beads are missing, it needs to be repaired later, which increases the construction steps and construction costs. Summary of the invention

[0004] The purpose of the present invention is to provide an integrated intelligent spraying device for road marking construction in response to the above-mentioned problems. The device intelligently links paint spraying with glass bead spreading, and automatically derives glass beads of corresponding particle sizes according to the paint thickness, so that the glass beads can effectively adhere to the paint, thereby preventing the loss of glass beads and waste of resources when the glass beads cannot adhere to the paint.
