Description

Technical Field

[0001] The present invention relates to the technical field of line marking machines, and in particular to a low-energy consumption diesel combustion heating type line marking machine. Background Art

[0002] A heating type line marking machine is an efficient road marking construction equipment. It heats the paint (such as hot melt type marking material) to a molten state through a built-in heating system, and then evenly applies it to the road surface by spraying or extrusion. Its characteristics are fast construction speed, strong adhesion of the marking, high durability, and the ability to maintain the fluidity of the paint in a low-temperature environment. It is suitable for occasions such as highways and urban roads that require long-lasting and clear markings. At the same time, the equipment is usually equipped with a temperature control system and an automatic spraying device to ensure uniform marking thickness and neat edges, improving the construction quality and safety.

[0003] For example, a diesel heating type traffic line marking machine disclosed in the publication number CN202420311964.7 includes a mobile frame. A pressurized oil tank and a burner are arranged on the mobile frame. Diesel is loaded into the pressurized oil tank. The burner is provided with an oil injection port and a flame spraying port. One end of the burner with the oil injection port is also provided with an oil inlet and an oil outlet. The outer end of the oil inlet is connected to the valve port of the pressurized oil tank by a first oil pipe. The inner end of the oil inlet is connected to the inner end of the oil outlet by a second oil pipe. The outer end of the oil outlet is connected to a third oil pipe. The outer end of the third oil pipe faces the oil injection port of the burner to form an oil injection path extending into the burner. The oil injection path intersects with the second oil pipe inside the burner. This diesel heating type traffic line marking machine simplifies the diesel combustion structure on the line marking machine, enabling the line marking machine to more conveniently use diesel as fuel, thereby solving the problem of difficult fuel replenishment outdoors.

[0029] The following will combine Figures 1-7 with the embodiments to further illustrate the present invention.

[0030] Embodiment 1

[0031] This embodiment discloses a low-energy-consumption diesel combustion heating type line marker.

[0032] Referring to Figure 1 , the low-energy-consumption diesel combustion heating type line marker includes a mobile frame 1 and a chassis 11, an oil tank 12, an air compressor 13, a burner 2 and a coating device arranged on the mobile frame 1. The coating device includes a material tank 14 and a hopper 15 for the coating to flow out in sequence. The coating device gradually coats the coating on the road surface as the mobile frame 1 moves to achieve line marking. The burner 2 is connected to the oil tank 12. In the present invention, diesel is loaded in the oil tank 12, and the burner 2 uses the diesel in the oil tank 12 to heat the hopper 15 of the coating device to ensure that the coating in the hopper 15 remains in a molten state, improving the line marking effect.

[0033] Referring to Figures 1 to 3 , the burner 2 includes an oil-gas mixing chamber 21, a preheating pipeline chamber 22 and a fire outlet 23 connected in sequence, and also includes an oil pipeline 3 and a wind pipeline 4. The oil-gas mixing chamber 21 is connected to the oil tank 12 through the oil pipeline 3 and is connected to the air compressor 13 through the wind pipeline 4. An oil valve 31 and an air valve 41 are respectively arranged on the oil pipeline 3 and the wind pipeline 4. A part of the pipe section of the oil pipeline 3 is a preheating pipe section 33, and the preheating pipe section 33 passes through the preheating pipeline chamber 22.

[0034] Based on the above settings, the heating process of the burner 2 for the hopper 15 of the coating device is as follows: First, ignition is carried out. When igniting, an external heat source is used to heat the preheating pipe section 33 in the preheating pipe chamber 22, which increases the internal pressure of the oil pipeline 3 and raises the temperature of the diesel flowing through the oil pipeline 3. Then, the oil valve 31 and the gas valve 41 are opened to mix the diesel and the gas required for combustion, improving the combustion performance of the diesel. Next, an external heat source is used to ignite at the fire outlet 23 of the burner 2 to achieve the open-flame combustion of the diesel and the heating of the hopper 15 of the coating device. During the open-flame combustion of the diesel, the combustion temperature is continuously fed back to the preheating pipe section 33 in the preheating pipe chamber 22, thereby continuously preheating the diesel to be burned and ensuring the continuous progress of the open-flame combustion of the diesel. Since in the present invention, there is no need to pressurize the oil tank 12, and the air compressor 13 is only used for mixing oil and gas, the power of the air compressor 13 is low and its size is small. Therefore, compared with the prior art, while achieving the open-flame combustion of diesel, the situation of using a high-power air compressor 13 is effectively avoided, reducing the safety risk of storing oil in the oil tank 12 and ensuring the stable storage characteristics of diesel.

[0035] Referring to Figures 1 to 3 , the preheating pipe chamber 22 includes a communication space 221 and a preheating space 222. The communication spaces 221 are arranged on the left and right sides of the preheating pipe chamber 22, and the two communication spaces 221 are respectively used to communicate with the oil-gas mixing chamber 21. Correspondingly, two fire outlets 23 are provided, and the two fire outlets 23 communicate with the two communication spaces 221. The preheating space 222 is located between the two communication spaces 221. The preheating pipe section 33 sequentially passes through the two communication spaces 221 and the preheating space 222. When igniting, the preheating pipe section 33 is preheated in the preheating space 222. Further, a cover plate 51 is hingedly provided at the top of the preheating space 222 of the preheating pipe chamber 22. The cover plate 51 is opened before ignition to facilitate heating the preheating pipe section 33 with an external heat source, and the cover plate 51 is closed after ignition to ensure that the open-flame combustion of diesel is output through the fire outlet 23. A convex block 52 is also provided at the top of the oil-gas mixing chamber 21, and the convex block 52 is used to support the opened cover plate 51 obliquely to limit the opening angle of the cover plate 51.

[0036] Embodiment 2

[0037] This embodiment also discloses a low-energy-consumption diesel combustion heating type line marker.

[0038] Referring to Figure 4 and Figure 5, the difference from the first embodiment is that the preheating pipe section 33 is movably arranged in the preheating pipeline bin 22, and the preheating pipe section 33 is movably connected to the cover plate 51. The preheating pipe section 33 moves to the middle of the preheating pipeline bin 22 as the cover plate 51 is opened, reducing the blockage of the side wall of the preheating pipeline bin 22 to the preheating pipe section 33, facilitating rapid heating of the preheating pipe section 33 before ignition. The preheating pipe section 33 also moves to a position close to the fire outlet 23 as the cover plate 51 is closed, so that the preheating pipe section 33 is as close as possible to the fire outlet 23 during the open flame combustion of diesel, improving the effect of the combustion heat being fed back to the preheating pipe section 33. Specifically, to achieve the effect of the preheating pipe section 33 being movably arranged in the preheating pipeline bin 22, the oil pipeline 3 is sequentially divided into an inlet pipe section 32, a preheating pipe section 33, and an outlet pipe section 34 along the flowing direction of diesel. The inlet pipe section 32 and the outlet pipe section 34 are arranged in parallel between the oil-gas mixing bin 21 and the preheating pipeline bin 22. The outlet pipe section 34 is communicated with the wind pipeline 4 and is provided with a mixing outlet. The two ends of the preheating pipe section 33 are respectively connected to the inlet pipe section 32 and the outlet pipe section 34 through two connectors 35, and the connectors 35 are L-shaped. Moreover, one end of the connector 35 away from the preheating pipe section 33 is fixedly connected with a telescopic pipe 36, and the telescopic pipe 36 is telescopically connected to the end of the inlet pipe section 32 or the end of the outlet pipe section 34. The movement of the preheating pipe section 33 is realized through the telescopic movement of the telescopic pipe 36. Further, a linkage structure is connected between the cover plate 51 and the preheating pipe section 33. The linkage structure includes a first connecting rod 61 and a second connecting rod 62 that are hinged to each other. The other end of the first connecting rod 61 is hinged to the cover plate 51, and the other end of the second connecting rod 62 is hinged with a rotating ring 63. The rotating ring 63 is rotatably sleeved on the preheating pipe section 33. When the cover plate 51 is closed, the first connecting rod 61 and the second connecting rod 62 are folded up accordingly, and the preheating pipe section 33 is pushed to move towards the direction close to the fire outlet 23. When the cover plate 51 is opened, the first connecting rod 61 and the second connecting rod 62 are unfolded accordingly, and the preheating pipe section 33 is pulled to move towards the middle of the preheating pipeline bin 22, realizing the linkage between the cover plate 51 and the preheating pipe section 33.

[0039] Refer to Figures 4 to 7, the preheating pipe section 33 is rotatably connected to the connector 35. A rotation control structure is provided on the preheating pipe section 33 and its moving path. The rotation control structure controls the preheating pipe section 33 to generate a rotation angle difference during the reciprocating movement, so that during adjacent two ignition processes, the external fire source heats different positions of the preheating pipe section 33, avoiding always heating the same position of the preheating pipe section 33 and causing local vulnerability, thereby improving the service life of the preheating pipe section 33. Specifically, the rotation control structure includes a toothed ring 71, an elastic rack 72 and a deformation ring 73. The toothed ring 71 is sleeved on the outer wall of the preheating pipe section 33. The elastic rack 72 is arranged at the bottom of the preheating pipe bin 22 and is located in the preheating space 222. The elastic rack 72 includes a bottom plate 721 and a plurality of teeth 722 elastically arranged on the top of the bottom plate 721. The elastic rack 72 meshes with the toothed ring 71 along the moving path of the preheating pipe section 33. The deformation ring 73 is sleeved at both ends of the preheating pipe section 33 and is embedded between the preheating pipe section 33 and the connector 35. The deformation ring 73 is made of a material with thermal expansion and contraction. In this embodiment, the deformation ring 73 is made of silicone rubber material. The silicone rubber material has a high coefficient of thermal expansion, a significant thermal expansion and contraction effect, and a high friction coefficient. In other embodiments, materials such as nitrile rubber and polyurethane can also be selected. Based on the setting of the above rotation control structure, before the preheating pipe section 33 is heated, since the deformation ring 73 is not heated and expanded, the rotation restriction of the deformation ring 73 on the preheating pipe section 33 is relatively low, so that during the process of the preheating pipe section 33 moving to the middle of the preheating pipe bin 22, the toothed ring 71 is easy to rotate as it meshes with the elastic rack 72, so that the preheating pipe section 33 has a large rotation angle; after the preheating pipe section 33 is heated, since the deformation ring 73 is heated and expanded and is squeezed between the end of the preheating pipe section 33 and the connector 35, the rotation restriction of the deformation ring 73 on the preheating pipe section 33 is relatively high, so that during the process of the preheating pipe section 33 moving to a position close to the fire outlet 23, the toothed ring 71 is difficult to rotate as it meshes with the elastic rack 72, but instead presses the teeth 722 into the bottom plate 721, so that the preheating pipe section 33 has a small rotation angle, and finally a rotation angle difference is formed.

[0040] The above are all preferred embodiments of the present invention, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
