[0008] The cooling component includes a water mist machine, a connecting shaft, and a telescopic cylinder. The connecting shaft is fixed to the side of the frame. The two sides of the upper end of the water mist machine are respectively connected to the connecting shaft through the connecting shaft and the telescopic cylinder to form a movable link, so as to drive the output shaft of the telescopic cylinder to extend and push the water mist machine to swing with the connecting shaft as a fulcrum. The water mist machine is provided with a nozzle, which is arranged toward the contact end between the edge of the asphalt layer and the road surface. The water mist machine sprays water mist toward the contact end between the edge of the asphalt layer and the road surface to reduce the temperature of the contact end, thereby accelerating the solidification speed of the asphalt at the contact end.

[0009] A preferred technical solution, the extrusion wheel is fixed to the frame by support frames arranged on the left and right sides, the outer diameter of the extrusion wheel gradually decreases from the middle to the two sides, and filling mechanisms are arranged at the ends of both sides of the extrusion wheel, the filling mechanisms protrude from the surface of the extrusion wheel, and the two filling mechanisms are respectively provided with raised rings on the side away from the middle of the extrusion wheel, the raised rings are arranged in an outwardly inclined shape, and the outer diameter of the raised ring is the same as the outer diameter of the middle part of the extrusion wheel.

[0010] A preferred technical solution, the filling mechanism includes an annular airbag, a push plate, and an electric push rod, each electric push rod is equipped with a push plate on its output shaft, and the annular airbag is sleeved outside all the push plates and abuts against them, when the outputs of all the electric push rods move the push plates inward, all the push plates form an annular structure, and the annular airbag contracts accordingly;

[0011] The annular airbag is provided with an air cavity inside, the air cavity is connected to the output shaft of the air pump through a connecting pipe, and the air pump creates a negative pressure to control the outer diameter of the annular airbag;

[0012] The left and right sides of the annular airbag are respectively provided with an anti-slip strip, and the annular airbag forms an interference fit with the extrusion wheel through the anti-slip strips on both sides.

[0013] A preferred technical solution, the limiting structure includes a support rod, a movable rod one, a movable rod two, and a movable seat, the support rod is installed on the frame through the movable seat, a rotational connection is formed between the support rod and the movable seat, a slide groove one is provided on the side of the support rod, and the movable rod one is slidably installed in the slide groove one through a sliding shaft installed at its end, and the middle part of the movable rod two is rotatably installed on the lower end of the movable rod one, and the side of the movable rod one has a sliding shaft for the movable rod two to be embedded.

[0014] A preferred technical solution is that the support rod is further provided with a second slide groove, and a slider is slidably installed in the second slide groove. The slider is connected to the side of the movable rod one through a spring. When the movable rod one swings downward, the spring is tightened.

[0015] An intelligent heating system, comprising the road paving equipment, comprising a heating module arranged at the bottom of the frame, the heating module being arranged between the extrusion wheel and the cooling component, the heating module comprising a combustion nozzle, a second connecting pipe, a pump, and an oil tank, the combustion nozzles being arranged equidistantly and connected to the side of the second connecting pipe, the second connecting pipe and the oil tank being connected to the output end and the input end of the pump respectively;

[0016] There are six combustion nozzles, which are respectively divided into R1, R2, R3, R4, R5 and R6. All the combustion nozzles 51 are used to heat the asphalt layer spread on the ground, wherein R1 and R6 constitute an intermittent heating module, wherein R2, R3, R4 and R5 constitute a continuous heating module. When the asphalt is discharged to the surface of the dispersion plate through the discharge port and spread on the road surface to form an asphalt layer, the asphalt layer is heated by the continuous heating module and the intermittent heating module to keep its fluidity. When the softened asphalt layer diffuses to the vicinity of the bottom of the cooling component, the cooling component sprays water mist on the contact point between the lower edge of the asphalt layer and the road surface, and at the same time stops heating the intermittent heating module, thereby reducing the temperature of the edge of the asphalt layer and accelerating the solidification speed.

[0017] Compared with the prior art, this technical solution has the following advantages:

[0018] The pavement paving equipment of the present invention cleverly integrates a limiting structure while squeezing the asphalt layer. This design effectively prevents the asphalt layer from falling off the edge of the pavement during the squeezing process. The mechanical force applied to the asphalt layer spread on the pavement by the squeezing wheel not only eliminates gaps and bubbles, improves the flatness and density, but also the limiting structure ensures that the asphalt layer can remain stable when squeezed and does not exceed the predetermined paving range. This innovation not only improves the accuracy and quality of paving, but also reduces material waste, providing a more efficient and accurate solution for pavement construction, which is significantly better than the problem of asphalt layers easily falling off the edge in traditional methods.

[0019] After the asphalt layer is spread and extruded, the cooling component begins to play its key role. The water mist machine, as the core component of the cooling component, forms a flexible movable link with the frame through the connecting shaft and the telescopic cylinder. This design enables the water mist machine to adjust the spraying angle and position as needed to ensure that the water mist can be accurately sprayed on the contact end of the edge of the asphalt layer and the road surface. The spraying of water mist quickly reduces the temperature of the area, thereby accelerating the solidification speed of the asphalt. The realization of this process effectively prevents the asphalt from flowing to the edge of the road surface, maintains the shape and dimensional stability of the asphalt layer, and further improves the paving effect.

[0020] By setting six combustion nozzles 51 and dividing them into continuous heating modules R2 to R5 and intermittent heating modules R1 and R6, the system can accurately control the heating area and time to ensure that the asphalt layer maintains appropriate fluidity during the paving process. This zoned heating design not only avoids the quality loss caused by overheating of the asphalt, but also ensures that the asphalt can be quickly softened when needed, thereby improving the paving efficiency. The coordinated use of the intermittent heating module and the continuous heating module enables the heating system to be flexibly adjusted according to the actual situation of the asphalt layer and the paving progress. When the asphalt layer spreads to near the bottom of the cooling component 6, the heating of the intermittent heating module can be stopped to quickly reduce the temperature of the edge of the asphalt layer, thereby accelerating the solidification speed and preventing the asphalt from flowing.

[0040] like Figures 1 to 10 As shown, the present invention proposes a road paving equipment and an intelligent heating system thereof, comprising a frame 1, an extrusion wheel 2, an asphalt tank 3, a limiting structure 4, a cooling component 6, and a dispersion plate 7. The asphalt tank 3 is arranged at the upper end of the frame 1, and the dispersion plate 7 is arranged at the lower end of the frame 1 corresponding to the asphalt tank 3. The lower end of the asphalt tank 3 is provided with three discharge ports 31, which are used to discharge the asphalt heated into a viscous state onto the dispersion plate 7 through the discharge ports 31, and evenly spread on the road surface through the dispersion plate 7 to form an asphalt layer. The extrusion wheel 2 is arranged at the lower end of the frame 1, and is used to extrude the asphalt layer spread on the road surface. The limiting structure 4 is symmetrically arranged on one side of the upper end of the frame 1 close to the extrusion wheel 2, and the cooling component 6 is symmetrically installed on the left and right sides of the frame 1, and is located between the asphalt tank 3 and the extrusion wheel 2;

[0041] The back of the dispersion plate 7 is fixed to the lower end of the frame 1 through a fixed back plate 71. The dispersion plate 7 has three inclined surfaces, each of which is provided with a guide groove 72. The guide groove 72 is a flared structure.

[0042] The cooling assembly 6 includes a water mist machine 61, a connecting shaft 63, and a telescopic cylinder 64. The connecting shaft 63 is fixed to the side of the frame 1. The two sides of the upper end of the water mist machine 61 are respectively connected to the connecting shaft 63 through the connecting shaft 63 and the telescopic cylinder 64 to form a movable link with the connecting shaft 63, so as to drive the output shaft of the telescopic cylinder 64 to extend and push the water mist machine 61 to swing with the connecting shaft 63 as a fulcrum. The water mist machine 61 is provided with a nozzle, which is arranged toward the contact end of the edge of the asphalt layer and the road surface. The water mist machine 61 sprays water mist toward the contact end of the edge of the asphalt layer and the road surface to reduce the temperature of the contact end, thereby accelerating the solidification speed of the asphalt at the contact end.

[0043] Here’s how it works:

[0044] Asphalt handling and discharge:

[0045] The core of the road paving equipment of the present invention lies in the precise processing and efficient discharge of asphalt. The asphalt tank 3, as the main component for storing and heating asphalt, is cleverly arranged at the upper end of the frame 1. During the heating process, the asphalt tank 3 is equipped with an advanced heating system, which can accurately control the temperature of the asphalt to ensure that it will not lose fluidity due to overheating when it reaches a viscous state, and will not be difficult to pave due to overcooling. After the heating is completed, the asphalt is evenly and continuously discharged to the dispersion plate 7 through the three discharge ports 31 at the lower end of the asphalt tank 3, which is fully prepared for the subsequent paving work;

[0046] Scattering, spreading and extrusion:

[0047] The dispersion plate 7 is another key component in the present invention. The back of the dispersion plate 7 is closely connected to the lower end of the frame 1 through a solid fixed structure fixed back plate 71. The dispersion plate 7 is ingeniously designed and has three inclined surfaces. A flared structure guide groove 72 is carefully arranged on each inclined surface. These structures can play a role of uniform dispersion when the asphalt flows through, ensuring that the asphalt is spread on the road surface with appropriate thickness and uniformity. Then, the extrusion wheel 2 plays its important role. It is located at the lower end of the frame 1 and squeezes the asphalt layer spread on the road surface through mechanical force. This process not only eliminates the gaps and bubbles in the asphalt layer, but also further improves the flatness and density of the asphalt layer, laying a solid foundation for subsequent solidification and curing.

[0048] Cooling and solidification:

[0049] After the asphalt layer is spread and extruded, the cooling component 6 begins to play its key role. The water mist machine 61, as the core component of the cooling component, forms a flexible movable link with the frame 1 through the connecting shaft 63 and the telescopic cylinder 64. This design enables the water mist machine 61 to adjust the spraying angle and position as needed to ensure that the water mist can be accurately sprayed on the contact end of the edge of the asphalt layer and the road surface. The spraying of water mist quickly reduces the temperature of the area, thereby accelerating the solidification speed of the asphalt. The realization of this process effectively prevents the asphalt from flowing to the edge of the road surface, maintains the shape and dimensional stability of the asphalt layer, and further improves the paving effect.

[0050] The extrusion wheel 2 is fixed to the vehicle frame 1 through support frames 21 arranged on the left and right sides. The outer diameter of the extrusion wheel 2 gradually decreases from the middle to the two sides. Filling mechanisms 22 are arranged at the ends of both sides of the extrusion wheel 2. The filling mechanisms 22 protrude from the surface of the extrusion wheel 2. The two filling mechanisms 22 are respectively provided with raised rings 23 on the side away from the middle of the extrusion wheel 2. The raised rings 23 are arranged in an outwardly inclined shape. This design enables the raised rings 23 to contact the asphalt layer in a progressive manner when the extrusion wheel 2 rotates, thereby avoiding sudden impact on the asphalt layer. The outer diameter of the raised ring 23 is the same as the outer diameter of the middle part of the extrusion wheel 2, which means that during the rotation of the extrusion wheel 2, the raised ring 23 can provide a continuous and uniform limiting surface for the asphalt layer.

[0051] When the extrusion wheel 2 rolls along the road surface under the push of the frame 1, the design of its outer diameter gradually decreasing from the middle to the two sides enables the extrusion wheel 2 to gradually compact the asphalt layer to the required thickness. The combination of the filling mechanism 22 and the raised ring 23 further enhances the limiting function of the extrusion wheel 2. The filling mechanism 22 protrudes from the surface of the extrusion wheel 2, providing a stable supporting foundation for the raised ring 23. When the extrusion wheel 2 rotates, the raised ring 23 contacts the asphalt layer with its outwardly inclined shape, and gradually pushes the asphalt layer to both sides, thereby forming a neat and uniform asphalt layer edge. Through the outwardly inclined limiting surface of the raised ring 23, the raised ring 23 can tightly squeeze the asphalt layer in the center of the road surface, ensuring the shape and dimensional stability of the asphalt layer.

[0052] Furthermore, the filling mechanism 22 includes an annular airbag 221, a push plate 222, and an electric push rod 223. A push plate 222 is installed on the output shaft of each electric push rod 223, and the annular airbag 221 is sleeved outside all the push plates 222 and abuts against them. When the output of all the electric push rods 223 moves the push plates 222 inward, all the push plates 222 form an annular structure, and the annular airbag 221 shrinks accordingly. When the output shaft of the electric push rod 223 moves inward, the push plates 222 will form an annular structure, and the annular airbag 221 will also shrink accordingly. This design allows the annular airbag 221 to be filled and contracted under the drive of the electric push rod 223, and the air pump 24 can create negative pressure to control the outer diameter of the annular airbag 221. This design allows the filling degree of the annular airbag 221 to be accurately adjusted by the air pump 24.

[0053] The annular airbag 221 has an air cavity inside, which is connected to the output shaft of the air pump 24 through a connecting pipe 2211, and the air pump 24 creates a negative pressure to control the outer diameter of the annular airbag 221;

[0054] In the initial state, the annular airbag 221 is in an unfilled state, and its outer diameter is relatively small. When the asphalt layer needs to be squeezed, the air pump 24 starts to work, and injects gas or creates negative pressure into the air cavity of the annular airbag 221 through the connecting pipe 1 2211, so that the annular airbag 221 is gradually filled and expanded. As the annular airbag 221 is filled and expanded, its outer diameter gradually increases, and it begins to contact with the asphalt layer and produce an extrusion effect. Since the material of the annular airbag 221 has certain elasticity and flexibility, it can adapt to the surface of the asphalt layer of different shapes and evenly distribute the extrusion force. During the extrusion process, the anti-slip strips 2212 on the left and right sides of the annular airbag 221 form an interference fit with the extrusion wheel 2, ensuring that the annular airbag 221 will not slide or fall off during the rotation of the extrusion wheel 2. This design improves the stability and reliability of the annular airbag 221.

[0055] The filling and expansion of the annular airbag 221 enables it to squeeze the asphalt layer in a gentle and uniform manner, which not only improves the density and flatness of the asphalt layer, but also avoids the asphalt layer from being broken or peeled off due to sudden impact. At the same time, the squeezing effect of the annular airbag 221 also helps to squeeze out the gaps and bubbles in the asphalt layer, making the asphalt layer more compact and uniform. This effect is of great significance for improving the durability of the road surface and reducing maintenance costs.

[0056] In addition, an anti-slip strip 2212 is respectively provided on the left and right sides of the annular airbag 221 , and the annular airbag 221 forms an interference fit with the extrusion wheel 2 through the anti-slip strips 2212 on both sides.

[0057] Furthermore, the limiting structure 4 includes a support rod 41, a movable rod 1 42, a movable rod 2 43, and a movable seat 44. The support rod 41 is installed on the vehicle frame 1 through the movable seat 44, and a rotation connection is formed between the support rod 41 and the movable seat 44. A slide groove 1 411 is provided on the side of the support rod 41, and the movable rod 1 42 is slidably installed in the slide groove 1 411 through a sliding shaft 421 installed at its end, and the middle part of the movable rod 2 43 is rotationally installed on the lower end of the movable rod 1 42, and the side of the movable rod 1 42 has a sliding shaft 421 for the movable rod 2 43 to be embedded, and the side of the movable rod 2 43 is provided with an adsorption magnetic strip 431. When the movable rod 2 43 is embedded in the sliding shaft 421, it is adsorbed in the sliding shaft 421 through the adsorption magnetic strip 431. This magnetic adsorption not only provides additional stability, but also allows the movable rod 1 and the movable rod 2 to be quickly and easily separated when necessary, so as to adjust or disassemble the limiting structure.

[0058] During the asphalt laying or transportation process, the limiting structure 4 forms an adjustable physical barrier through the combination of the support rod 41, the movable rod 42-1 and the movable rod 2-43. By adjusting the position of the movable rod 1 42 in the slide groove 1 411, and the rotation and sliding of the movable rod 2-43 relative to the movable rod 1 42, the shape and size of the limiting structure can be precisely controlled, thereby effectively limiting the diffusion range of the asphalt layer.

[0059] A preferred technical solution is that the support rod 41 is further provided with a second slide groove 412, and a slider 413 is slidably installed in the second slide groove 412. The slider 413 is connected to the side of the movable rod 1 42 through a spring 414. When the movable rod 1 42 swings downward, the spring 414 is tightened. Embodiment 2

[0060] like Fig.11 As shown, in this embodiment, an intelligent heating system is proposed, including the road paving equipment, including a heating module 5 arranged at the bottom of the frame 1, the heating module 5 is arranged between the extrusion wheel 2 and the cooling component 6, the heating module 5 includes a combustion nozzle 51, a second connecting pipe 52, a pump 53, and an oil tank 54, the combustion nozzle 51 is arranged equidistantly and connected to the side of the second connecting pipe 52, the second connecting pipe 52 and the oil tank 54 are respectively connected to the output end and the input end of the pump 53;

[0061] There are six combustion nozzles 51, which are respectively divided into R1, R2, R3, R4, R5 and R6. All the combustion nozzles 51 are used to heat the asphalt layer spread on the ground, wherein R1 and R6 form an intermittent heating module, wherein R2, R3, R4 and R5 form a continuous heating module. When the asphalt is discharged to the surface of the dispersion plate 7 through the support frame 21 and spread on the road surface to form an asphalt layer, the asphalt layer is heated by the continuous heating module and the intermittent heating module to keep its fluidity. When the softened asphalt layer diffuses to the bottom of the cooling component 6, the cooling component 6 sprays water mist on the contact point between the lower edge of the asphalt layer and the road surface, and at the same time stops heating the intermittent heating module, thereby reducing the temperature of the edge of the asphalt layer and accelerating the solidification speed. By setting six combustion nozzles 51 and dividing them into continuous heating modules R2 to R5 and intermittent heating modules R1 and R6, the system can The heating area and time can be precisely controlled to ensure that the asphalt layer maintains appropriate fluidity during the paving process. This zoned heating design not only avoids quality loss caused by overheating of the asphalt, but also ensures that the asphalt can be quickly softened when needed, thereby improving the paving efficiency; the coordinated use of the intermittent heating module and the continuous heating module enables the heating system to be flexibly adjusted according to the actual situation of the asphalt layer and the paving progress. When the asphalt layer diffuses to near the bottom of the cooling component 6, the temperature of the edge of the asphalt layer can be quickly reduced by stopping the heating of the intermittent heating module, thereby accelerating the solidification speed and preventing the asphalt from flowing; the heating system ensures that the asphalt maintains an appropriate temperature during the paving process, thereby improving the flatness and density of the asphalt layer. At the same time, the timely action of the cooling component effectively prevents the flow and deformation of the edge of the asphalt layer, maintains the shape and dimensional stability of the asphalt layer, and further improves the paving quality.

[0062] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.

An intelligent heating system, comprising the road paving equipment according to any one of claims 1 to 5, characterized in that: The vehicle comprises a heating module (5) arranged at the bottom of the vehicle frame (1), the heating module (5) being arranged between the extrusion wheel (2) and the cooling component (6), the heating module (5) comprising a combustion nozzle (51), a second connecting pipe (52), a pump (53), and an oil tank (54), the combustion nozzles (51) being arranged at equal distances and connected to the side of the second connecting pipe (52), the second connecting pipe (52) and the oil tank (54) being connected to the output end and the input end of the pump (53) respectively; The number of the combustion nozzles (51) is six, which are respectively divided into R1, R2, R3, R4, R5, and R6. All the combustion nozzles (51) are used to heat the asphalt layer spread on the ground, wherein R1 and R6 form an intermittent heating module, and wherein R2, R3, R4, and R5 form a continuous heating module. When the asphalt is discharged to the surface of the dispersion plate (7) through the discharge port (31) and spread on the road surface to form an asphalt layer, the asphalt layer is heated by the continuous heating module and the intermittent heating module to maintain fluidity. When the softened asphalt layer diffuses to the bottom of the cooling component (6), the cooling component (6) sprays water mist on the contact point between the lower edge of the asphalt layer and the road surface, and at the same time stops heating the intermittent heating module, thereby reducing the temperature of the edge of the asphalt layer and accelerating the solidification speed.
