Description

Technical Field

[0001] The invention relates to the technical field of road administration marking devices, in particular to an anti-stone walking type automatic marking device for municipal road paving. Background Art

[0002] During highway construction, it is necessary to mark the road surface, such as zebra crossings, road dividers and some markings. Usually, hot melt markings, room temperature cold paint markings, colored anti-skid markings, oscillating anti-skid reflective markings and preformed markings are used. Usually, a marking machine is used for marking and marking. On some large highways or national highways, a marking vehicle is usually used. The driver drives the marking vehicle to move the marking vehicle for marking and marking. However, in some towns, farms or urban communities, hand-push marking machines are more often used for marking.

[0003] When marking roads, the hand-pushed road marking machine in the related art pushes the hand-pushed road marking machine to move and mark the roads in order to make the paint or varnish adhere to the roads or paths. However, the width of the marking lines cannot be adjusted directly, and the paint roller of the corresponding width needs to be replaced for marking, which is inconvenient to operate. When paving roads, it is often necessary to use marking lines of different sizes, which is inconvenient to operate. When marking roads, there is a lot of debris and pebbles on the paved road surface, which will cause the marking paint to fall on the soil and rocks. After the soil and rocks move, there will be gaps in the marking path, which affects the quality of the markings. In addition, the soil and rocks may also get stuck on the paint roller, which directly affects the subsequent markings. The efficiency of manual cleaning is low, resulting in a waste of manpower.
