Description

Technical Field

[0001] The invention relates to the technical field of road construction equipment, and in particular to a diesel-heated road marking machine and its application. Background Art

[0002] In the construction of road traffic facilities, road marking is a vital part, which provides clear traffic instructions for vehicles and pedestrians and ensures traffic order and safety. As a key equipment for achieving road marking operations, the performance and efficiency of road marking machines directly affect the quality and progress of road marking work.

[0003] At present, the existing road marking machines on the market have many deficiencies in heating methods. Some road marking machines use gas heating, and the gas supply is limited by many factors such as gas source and pipeline laying. In some remote areas or under limited conditions of construction sites, it is difficult to ensure a stable gas supply, which brings great inconvenience to the marking operation. Moreover, during the gas combustion process, the sufficiency of combustion is greatly affected by factors such as gas quality and burner design, and incomplete combustion is prone to occur, which not only causes energy waste, but also produces harmful gas emissions and pollutes the environment.

[0004] Another part of the marking machine directly burns diesel for heating, but this heating method also has the problem of low efficiency. When burning diesel directly, the combustion process is difficult to accurately control, heat loss is serious, and most of the heat cannot be effectively used to heat the marking material, resulting in low energy utilization and increased costs of marking operations.

[0005] In addition, existing marking machines also have defects in burner design. Many marking machines are only equipped with a single type of burner, or although there are two burners, the structures and functions of the two burners are basically the same, and they cannot be optimized according to the heating requirements of different links in the marking operation. For example, there are differences in the heating temperature, heating speed and other parameters required for heating the marking material at the bottom of the material tank and the secondary heating of the marking material behind the discharge port. Burners with the same structure are difficult to meet these different heating requirements at the same time, resulting in the overall heating efficiency not being able to reach the optimal state, which in turn affects the efficiency and quality of the marking operation.

[0006] In summary, there are many problems that need to be solved in the heating method and burner design of existing road marking machines. In order to meet the growing demand for road marking, improve the efficiency and quality of marking operations, and reduce energy consumption and environmental pollution, it is of great practical significance to develop a new and efficient road marking machine.

Mobile wheels 2 are arranged below the mobile frame 1 to facilitate the movement and operation of the marking machine.

[0026] The rear fire burner 16 is arranged behind the discharge port 14 and is fixedly connected to the discharge port 14. When the marking material enters the discharge port 14 from the guide plate 13, its main function is to prevent the marking material at the discharge port 14 from solidifying due to too low temperature. As Figure 2 shown, the rear fire burner 16 includes a first rear fire oil pipe 17, one end of the first rear fire oil pipe 17 is connected to a second rear fire oil pipe 18, and a third rear fire oil pipe 19 is connected above the second rear fire oil pipe 18.

During the marking process, the glass beads are transported from the bead box 3 to the bead hopper 4 through the pipeline and scattered on the just-marked line to improve the reflective performance of the line.

[0031] An oil outlet main valve 9, a bottom-fire oil outlet valve 10, and an after-fire oil outlet valve 11 are arranged at the outer end of the oil tank 6, which are respectively used to control the total oil output, the oil output of the bottom-fire burner 15, and the oil output of the after-fire burner 16.
