Description

Technical Field

[0001] The present application relates to the technical field of road marking, and in particular to a road spray marking machine. Background Art

[0002] The marking machine is a road construction machine widely used in roads, highways, parking lots, squares and runways to mark different restrictions, guidance and warning signs on the flat ground. The marking machine has played a huge role in urban planning and highway construction with its advantages of fast, efficient and accurate, saving the construction period and economic investment of road construction to the greatest extent. In the process of road maintenance and reconstruction, it is necessary to mark the road surface with markings to facilitate pedestrians and vehicles to better comply with traffic regulations and reduce the occurrence of safety accidents.

[0003] The existing technology still has the following problems:

[0004] 1. The existing marking machine does not stir the paint evenly enough. During the paint stirring process, the stirring efficiency of the existing stirring mechanism is relatively low, and the solid particles mixed in the paint are easy to settle at the bottom of the stirring kettle, making it difficult to mix and stir the particles, resulting in uneven stirring of the paint, resulting in large color differences in the lines drawn during the marking process, thus affecting the later service life.

[0005] 2. The existing road marking machine cannot clean the road surface when marking. Since there is relatively much dust on the road surface, if there is dust on the road surface and it is not cleaned when marking, the dust will fly away with the wind after marking, thus taking away the paint sprayed on the dust, making the line drawn by the road marking machine unclear, affecting the effect of the marking.

[0006] 3. Paint is easily attached to the bottom of the coating bucket during the marking process, and dripping on the ground can easily make the marking uneven and waste paint. The existing marking machine cannot collect the paint attached to the bottom of the coating bucket for a second time. When some marking machines collect through other containers, it is difficult to find out how much the container has collected. When the container is full, it is easy to overflow, which also leads to paint waste. In addition, the width of the lines marked by the existing marking machine is fixed and the fault tolerance is low. Summary of the invention

[0018] The technical solution provided by this application has at least the following technical effects or advantages:

[0019] 1. The use of a stirring kettle assembly effectively solves the problem of uneven stirring of paint in existing marking machines. During the paint stirring process, the stirring efficiency of the existing stirring mechanism is relatively low, and solid particles mixed in the paint are easily settled at the bottom of the stirring kettle, making it difficult to mix and stir the particles, resulting in uneven stirring of the paint, resulting in large color differences in the lines drawn during the marking process, thereby affecting the service life in the later period. The present invention can perform dual stirring in the forward and reverse directions through the stirring kettle assembly, thereby improving the stirring efficiency, and at the same time can drive the particles attached to the bottom of the kettle body to shake, prevent the particles from settling, and stir the particles, thereby stirring the paint more evenly, thereby ensuring color uniformity when marking.

[0020] 2. The use of the obstacle-clearing component effectively solves the problem that the existing road marking machine cannot clean the road surface when marking. Since there is relatively much dust on the road surface, if there is dust attached to the road surface and it is not cleaned when marking, the dust will fly away with the wind after marking, thereby taking away the paint sprayed on the dust, making the line drawn by the road marking machine unclear, affecting the effect of the marking. The present invention can clean the road surface through the obstacle-clearing component, making the drawn lines clearer, and at the same time can adjust the angle of the cleaning disc, which is convenient for use on a slope, thereby better cleaning the road surface.

[0021] 3. The coating component is adopted, which effectively solves the problem that the bottom of the coating bucket is easy to adhere to the paint during the line drawing process, and the paint dripping on the ground makes the marking uneven and wastes the paint. The existing marking machine cannot collect the paint attached to the bottom of the coating bucket for a second time. When some marking machines collect through other containers, it is difficult to find out how much the container has collected. When the container is full, it is easy to overflow, which also leads to paint waste. In addition, the width of the line drawn by the existing marking machine is fixed and the fault tolerance is low. The present invention can block the coating bucket through the coating component when the marking is stopped to prevent the paint from continuing to flow out. When marking, the paint attached to the bottom of the coating bucket can be guided to facilitate the collection of the paint for secondary use, while avoiding the paint dripping on the line and affecting the color of the line. In addition, it has an alarm mechanism, which can remind the staff to handle it after the paint has collected a certain weight. In addition, the width of the line can be adjusted according to the actual situation, which improves the fault tolerance of the marking machine. BRIEF DESCRIPTION OF THE DRAWINGS
