Description

Technical Field

[0001] The invention belongs to the field of highway engineering machinery and equipment, and in particular relates to a highway marking machine. Background Art

[0002] Highway marking machine is a highway engineering equipment used to mark guidance, warning and other indicating markings on flat roads such as highways, parking lots, squares and runways. Hot-melt paint highway marking machine has become a commonly used highway marking machine due to its high wear resistance, strong reflectivity and high cost-effectiveness. In order to increase the adhesion between the sprayed paint coating and the ground, reduce the shedding of the markings and increase the service life of the markings, it is usually chosen to clean the pollutants such as grease, dust and sand on the road surface before spraying the paint by the highway marking machine. After cleaning, dust is flying in the air, and dust can easily fall to the position to be marked. When the highway marking machine sprays paint on the dusty road surface, the paint will not be tightly adhered, the markings will easily fall off after long-term use, and the service life will be short. In addition, the paint dries slowly after the hot-melt paint highway marking machine sprays the paint for marking, the road occupancy time is long, the construction efficiency is low, and there are certain safety hazards affecting traffic. Summary of the invention

[0003] The present invention aims to provide a highway marking machine to solve the problem that before the highway marking machine sprays paint, pollutants such as grease, dust, sand and the like on the road surface must be cleaned before spraying. After cleaning, dust in the air is flying, and the dust can easily fall to the position to be marked. When the highway marking machine sprays paint on a dusty road surface, the paint will not adhere tightly, the marking line will easily fall off after long-term use, and the service life will be short. In addition, after the hot-melt paint highway marking machine sprays the paint for marking, the paint dries slowly, the road occupancy time is long, the construction efficiency is low, and the traffic is affected, and there will be certain safety hazards.

[0004] To achieve the above purpose, the specific technical solution of a highway marking machine of the present invention is as follows:

[0005] A highway marking machine comprises a main frame; a barrel is arranged on the upper side of the main frame; a conveying pipe is arranged at the bottom of the barrel; a nozzle is arranged on the lower side of the main frame through the conveying pipe; a control valve is arranged on the conveying pipe; a first motor is arranged on the upper side of the barrel; a stirring blade is arranged on the output shaft of the first motor extending into the barrel; a plurality of cleaning brushes are arranged on the main frame for rotation on one side of the nozzle; a pulley is arranged on the upper side of the cleaning brush extending to the upper side of the main frame; a plurality of pulleys are connected by belts; a second motor is arranged on the upper side of a pulley of the main frame; the second motor drives the relative pulley to rotate; a dust suction bin is arranged on the lower side of the main frame between the cleaning brush and the nozzle; a dust filter bin is arranged on the main frame on one side of the barrel; a plurality of negative pressure pipes are arranged on one side of the dust filter bin and extend to the lower side of the main frame to communicate with the dust suction bin; a fan is arranged on one side of the dust filter bin.

[0006] Furthermore, a heating tube is arranged around the barrel wall.

[0007] Furthermore, a mounting plate is arranged on the lower side of the main body at an end away from the cleaning brush; a plurality of fans are arranged on the mounting plate; and a heating plate group is arranged on the lower side of the plurality of fans.

[0008] Furthermore, two indicating columns are arranged on one side of the main body; the two indicating columns are respectively opposite to the ends of both sides of the nozzle; and an indicating mark is arranged on the upper end of the indicating column.

[0009] The road marking machine of the present invention has the following advantages: by arranging a plurality of cleaning brushes driven by a second motor on one side of a main frame, the road surface to be marked can be cleaned before the road marking machine is used for spraying paint and marking, and grease, dust and sand on the road surface can be cleaned and separated from the road surface; the fan provides negative pressure for the dust filter bin, the negative pressure pipe and the dust suction bin, and the dust flying up from the road surface cleaned by the cleaning brush is sucked in from the dust suction bin and enters the dust filter bin for filtration through the negative pressure pipe, thereby preventing dust in the air from flying after cleaning by the cleaning brush, and the dust from falling to the position to be marked, which affects the adhesion effect of subsequent paint spraying, and can effectively increase the adhesion between the sprayed paint coating and the ground, reduce the shedding of the marking line and increase the service life of the marking line; in the process of using the road marking machine for paint spraying and marking, the paint in the barrel is continuously stirred by the stirring blades driven by the first motor, and at the same time, the heating pipe arranged around the inner wall of the barrel continuously heats the barrel, and the stirring blades driven by the first motor stir the paint in the barrel Stirring the material can ensure the uniformity of the paint in the barrel, prevent the paint from having a local concentration that is too high or too low in the barrel, prevent the paint from settling or agglomerating, prevent the nozzle from being blocked, and improve the utilization rate of the paint. Continuously heating the paint through the heating tube can stably maintain the construction temperature of the paint, maintain good fluidity and adhesion of the paint, facilitate spraying by the nozzle, and effectively ensure the quality of the sprayed marking line. By arranging a plurality of fans and a heating plate group on the lower side of the main body, when the paint is sprayed onto the road surface by the nozzle and has not yet dried, the fan blows air to the heating plate group, and the heating plate group is started at the same time to heat the air blown out by the fan, and the hot air is used to dry the paint marking line that has not yet dried, so that the solvent in the paint marking line evaporates quickly, thereby promoting the drying and curing of the paint marking line coating, thereby accelerating the drying speed of the paint marking line, reducing the time of traffic occupying the road, increasing construction efficiency, and greatly avoiding the safety hazards caused by highway marking work.
