Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction equipment technology, and in particular to a diesel-heated road marking machine. Background Technology
[0002] Road marking is a crucial part of road traffic infrastructure construction, providing clear traffic directions for vehicles and pedestrians and ensuring traffic order and safety. As a key piece of equipment for marking operations, the performance and efficiency of road marking machines directly affect the quality and progress of the work.
[0003] Currently, existing road marking machines on the market have many shortcomings in their heating methods. Some machines use gas heating, but the gas supply is limited by various factors such as gas source and pipeline laying. In some remote areas or where construction site conditions are limited, it is difficult to guarantee a stable gas supply, which brings great inconvenience to the marking operation. Moreover, during the gas combustion process, the completeness of combustion is greatly affected by factors such as gas quality and burner design, and incomplete combustion is prone to occur. This not only wastes energy but also produces harmful gas emissions, causing environmental pollution.
[0004] Another type of line marking machine uses diesel fuel for heating; however, this heating method also suffers from inefficiency. When burning diesel fuel directly, the combustion process is difficult to control precisely, resulting in significant heat loss. Most of the heat is not effectively used to heat the line marking material, leading to low energy efficiency and increased costs for line marking operations.
[0005] Furthermore, existing marking machines also have deficiencies in burner design. Many marking machines are equipped with only a single type of burner, or although they have two burners, the two burners have essentially the same structure and function, making it impossible to optimize them for the specific heating requirements of different stages in the marking process. For example, the heating temperature and heating rate required for the two stages—heating the marking material at the bottom of the tank and the secondary heating of the marking material after the discharge port—are different. Burners with the same structure cannot simultaneously meet these different heating requirements, resulting in overall heating efficiency that cannot reach its optimal state, thus affecting the efficiency and quality of the marking operation.
[0006] In summary, existing road marking machines have many problems that urgently need to be solved in terms of heating methods and burner design. 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 type of efficient road marking machine.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0028] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.
[0029] Example 1
[0030] like Figure 1 As shown, this utility model provides a diesel-heated road marking machine, mainly comprising a mobile frame 1, on which a bead box 3, an air box 5, an oil tank 6, and a material tank 12 are sequentially arranged. The mobile frame 1 is equipped with casters 2 at its base for easy movement and operation of the marking machine.
[0031] The afterburner 16 is located 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 excessively low temperature. Figure 2 As shown, the afterburner 16 includes a first afterburner oil pipe 17, one end of which is connected to a second afterburner oil pipe 18, and a third afterburner oil pipe 19 is connected above the second afterburner oil pipe 18. A first air inlet 20 is provided at one end of the third afterburner oil pipe 19, and both the third afterburner oil pipe 19 and the first air inlet 20 are connected to a first combustion chamber 21. A first flame outlet 22 is provided at one end of the first combustion chamber 21, and the first flame outlet 22 is fixedly connected to the first combustion chamber 21. Furthermore, the afterburner 16 has an internal groove for collecting unburned diesel fuel to reduce energy waste.
[0032] During operation, diesel fuel enters the first afterburner oil pipe 17 through the afterburner outlet valve 11 at the outer end of the oil tank 6, and then sequentially enters the second afterburner oil pipe 18 and the third afterburner oil pipe 19. During this process, the diesel fuel gradually vaporizes. Simultaneously, external air enters the first air inlet 20 through the first air inlet pipe 7 and mixes with the vaporized diesel fuel. Under the ignition of an external flame source, the mixture burns in the first combustion chamber 21, generating heat to heat the discharge port 14, thereby preventing the marking material from solidifying at the discharge port 14.
[0033] The bottom burner 15 is located at the bottom of the material tank 12, and its main function is to prevent the marking material inside the material tank 12 from solidifying due to excessively low temperature. Figure 3 As shown, the primer burner 15 includes a first primer oil pipe 23, and a second primer oil pipe 24 is disposed above the first primer oil pipe 23. The other end of the second primer oil pipe 24 is connected to a second air inlet 27. The end of the second air inlet 27 is a second flame outlet 26, and a second combustion chamber 25 is disposed outside the second flame outlet 26. The first primer oil pipe 23 passes through the second flame outlet 26, the second combustion chamber 25, and is connected to the second primer oil pipe 24 in sequence.
[0034] During operation, diesel fuel enters the first primer pipe 23 through the primer outlet valve 10 at the outer end of the tank 6, and then enters the second primer pipe 24, during which time the diesel fuel gradually vaporizes. Simultaneously, external air enters the second air inlet 27 through the second air inlet pipe 8, mixing with the vaporized diesel fuel. Ignition by an external flame source causes the mixture to burn in the second combustion chamber 25, generating heat to heat the bottom of the tank 12, thereby preventing the marking material inside the tank 12 from solidifying.
[0035] The bead box 3 is connected to the bead hopper 4 via a pipe, and the bead hopper 4 is located behind the afterburner 16. During the marking process, glass beads are transported from the bead box 3 to the bead hopper 4 via the pipe and spread on the newly marked lines to improve the reflectivity of the lines.
[0036] The outer end of the oil tank 6 is equipped with a main oil outlet valve 9, a primer oil outlet valve 10, and a afterburner oil outlet valve 11, which are used to control the total oil output, the oil output of the primer burner 15, and the oil output of the afterburner burner 16, respectively. The outer end of the gas box 5 is connected to a first air inlet pipe 7 and a second air inlet pipe 8, which are used to provide air to the afterburner burner 16 and the primer burner 15 for combustion support, respectively.
[0037] The heating principle of the burner in this device is as follows:
[0038] In the primer burner 15, diesel fuel enters the first primer oil pipe 23 of the primer burner 15 through the primer oil outlet valve 10 at the outer end of the oil tank 6, and then enters the second primer oil pipe 24. During this process, the diesel fuel gradually vaporizes. External air enters the second air inlet 27 through the second air inlet pipe 8 at the outer end of the air box 5 and mixes with the vaporized diesel fuel. Under the ignition of an external fire source, the mixed gas burns in the second combustion chamber 25, generating heat to heat the bottom of the material tank 12 and prevent the marking material inside the material tank 12 from solidifying.
[0039] In the afterburner 16, diesel fuel enters the first afterburner oil pipe 17 through the afterburner oil outlet valve 11 at the outer end of the oil tank 6, and then sequentially enters the second afterburner oil pipe 18 and the third afterburner oil pipe 19. During this process, the diesel fuel gradually vaporizes. External air enters the first air inlet 20 through the first air inlet pipe 7 at the outer end of the air box 5 and mixes with the vaporized diesel fuel. Under the ignition of an external flame source, the mixed gas burns in the first combustion chamber 21, generating heat to heat the discharge port 14 and prevent the marking material from solidifying at the discharge port 14. At the same time, a trough is provided inside the afterburner 16 to collect unburned diesel fuel to reduce energy waste.
[0040] Therefore, this utility model adopts the aforementioned diesel-heated road marking machine. By using diesel heating, it effectively overcomes the limitations of gas supply and significantly improves the applicability of the marking machine in various construction environments. At the same time, by optimizing the diesel combustion process, more complete combustion is achieved, greatly reducing energy waste and harmful gas emissions. In addition, the unique structural design of the bottom burner and the afterburner not only meets the heating needs of different stages in the marking operation, but also realizes the differentiated design of the burners, giving full play to their respective performance advantages, thereby improving the overall working efficiency and marking quality of the marking machine.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
