Description

Technical Field

[0001] The present invention relates to the technical field of road marking, and particularly to a road edge line marking vehicle with offset cold spraying. Background Art

[0002] Road marking refers to the markings on the road surface, such as lines, arrows, words, elevation markings, raised road signs, and contour markers, etc., which convey traffic information such as guidance, restriction, and warning to traffic participants. Its function is to control and guide traffic, and it can be used in combination with signs or alone. The marking methods can be divided into hot melt marking and cold spray marking.

[0003] In some places with cold weather, when it is not suitable to use hot melt markings, cold spray coatings can be used for marking. During road renovation construction, temporary markings are required, and cold spray coating markings can be used at this time to reduce subsequent cleaning work. However, currently, when the paint in the marking machine runs out, it is necessary to manually open the paint bucket by workers and pour the paint inside into the storage bucket of the marking machine, which is prone to splashing and causing skin damage. Moreover, since many buckets of paint need to be poured into the storage bucket, when the work is over, there are often a lot of unused paints left. Storing them will cause the paint to precipitate, which will affect the quality of the marking construction, and discarding them will cause waste. Therefore, there is an urgent need for a road edge line marking vehicle with offset cold spraying to solve the above problems. Summary of the Invention
