Description

Technical Field

[0001] This application relates to the field of asphalt paving, and in particular to an asphalt paving device and method for municipal roads. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mainly used in industries such as coatings, plastics, and rubber, as well as in road paving.

[0003] In related technologies, when asphalt is used for road paving, it needs to be placed into a paving device. The paving device mainly includes a mobile vehicle, a cleaning brush, and a storage tank containing asphalt. The cleaning brush is rotatably connected to the front end of the mobile vehicle, the storage tank is set on the mobile vehicle, and the mobile vehicle is equipped with a pressure plate.

[0004] Regarding the aforementioned technologies, the inventors discovered that when cleaning the road surface with a cleaning brush, a large amount of dust is easily stirred up. This dust is easily mixed into the asphalt, increasing the impurities in the asphalt and thus reducing the quality of the road surface. Therefore, improvements are needed. Summary of the Invention

[0005] To address the aforementioned issues, this application provides an asphalt paving device and an asphalt paving method for municipal roads.

[0006] This application provides a municipal road asphalt paving device, which adopts the following technical solution:

[0007] A municipal road asphalt paving device includes a frame. Along its length, the frame is sequentially equipped with a cleaning component, a dust suppression component, and a storage tank. The storage tank contains a mixing component. The frame has a drive component for driving the mixing component. A discharge port connected to the storage tank is located on the frame. The storage tank contains a quantity control component for controlling the amount of asphalt. The dust suppression component includes a water tank and a water pump. The water tank is connected to the cleaning component via a connecting pipe. The water pump is disposed within the connecting pipe. The frame has a speed-changing component for controlling the water delivery frequency of the water pump. The speed-changing component is connected to the drive component and to the quantity control component via a connecting component.

[0008] By adopting the above technical solution, when asphalt needs to be laid on the road surface, the operator puts the asphalt into a storage bucket, starts the drive component, and the drive component controls the mixing component to start. The mixing component stirs the asphalt, making it less likely to solidify. The operator then uses the quantity control component to control the asphalt output according to different construction requirements. When the quantity control component is working, the speed change component starts under the action of the connecting component. The speed change component controls the water delivery frequency of the pumping component, and the drive component simultaneously provides power to the pumping component. The pumping component then delivers water to the cleaning component, reducing dust generation and making it less likely for dust to mix into the asphalt, thereby improving the paving quality of the road surface.

[0009] Preferably, the measurement control component includes a first measurement control plate and a second measurement control plate, which are disposed opposite to each other in a storage container. Both the first and second measurement control plates are slidably connected in the storage container. A control plate, a first pulley, and a second pulley are rotatably connected to the frame. A first pull rope is connected to the first measurement control plate, which is wound around the first pulley and connected to one end of the control plate. A second pull rope is connected to the second measurement control plate, which is wound around the second pulley and connected to the other end of the control plate. The control plate is connected to a connecting component.

[0010] By adopting the above technical solution, when it is necessary to control the asphalt discharge rate, the operator rotates the control panel, which simultaneously pulls the first and second pull ropes. The first pull rope drives the first pulley to rotate, and the second pull rope drives the second pulley to rotate. The first pull rope then moves the first control plate, and the second pull rope then drives the second control plate to rotate, thereby achieving the function of controlling the asphalt discharge rate. At the same time, the action of the first and second pulleys increases the prestress inside the first and second pull ropes, reducing the possibility of damage to the first and second pull ropes.

[0011] Preferably, the pumping component includes a transfer pipe and a piston block. The transfer pipe is connected to a connecting pipe, and the piston block is slidably connected in the transfer pipe. The end of the piston block away from the transfer pipe is connected to the speed transmission assembly through a control component.

[0012] By adopting the above technical solution, when the operator adjusts the asphalt discharge rate, the control plate drives the connecting component to rotate, and the connecting component then drives the control component to rotate to adjust the position of the control component. At this time, the drive component controls the control component to start. After the speed change is completed, the control component drives the piston block to move back and forth along the transfer pipe. At this time, the control component changes the frequency of the piston block's reciprocating movement so that the water delivery frequency of the pumping component can be adapted to the road surface with different construction requirements.

[0013] Preferably, the connection between the connecting pipe and the cleaning component is rotatably connected to two opposing baffles, which abut against each other, and a torsion spring is wound around the rotating shaft of each of the opposing baffles.

[0014] By employing the above technical solution, under the elastic force of the torsion spring, the two opposing baffles abut against each other. At this time, the baffles block the connecting pipe and the cleaning assembly, making it difficult for the water conveyed by the piston block towards the cleaning assembly to flow back. When the piston block conveys water into the cleaning assembly, both baffles rotate away from the connecting pipe, and the torsion spring is in a compressed state. After the water delivery is completed, under the restoring force of the torsion spring, the two baffles simultaneously return to their original positions, so that the two opposing baffles can stably seal the connecting pipe.

[0015] Preferably, the transmission assembly includes a control base, a first rotating shaft, and a second rotating shaft. The first and second rotating shafts are offset from each other on the control base. Both the first and second rotating shafts are rotatably connected to the control base. A first control bevel gear is rotatably connected to both ends of the first rotating shaft, and a second control bevel gear is rotatably connected to both ends of the second rotating shaft. The diameter of the first control bevel gear is d1, and the diameter of the second control bevel gear is d2. <d2;

[0016] The control component includes a drive disc, an adapter bevel gear, and a connecting rod. The drive disc is rotatably connected to the frame. The adapter bevel gear is coaxially mounted on the shaft of the drive disc. The connecting rod is rotatably connected to the side of the drive disc away from the adapter bevel gear. The end of the connecting rod away from the drive disc is rotatably connected to a piston block. The first and second control bevel gears near the drive assembly both cooperate with the drive assembly. The first and second control bevel gears near the adapter bevel gear both cooperate with the adapter bevel gear.

[0017] By adopting the above technical solution, when the operator adjusts the asphalt discharge rate, the operator rotates the control panel. Under the action of the connecting component, the control panel drives the control seat, the first rotating shaft, and the second rotating shaft to rotate. When the asphalt discharge rate is low, the first control bevel gear near the drive component engages with the drive component, and the first control bevel gear near the adapter bevel gear meshes with the adapter bevel gear. At this time, the drive component can control the drive disc to rotate. The rotation of the drive disc drives the connecting rod to rotate. Under the limiting action of the adapter pipe, the connecting rod drives the piston block to reciprocate in the adapter pipe. During the reciprocating movement of the piston block, water in the water tank can enter the cleaning component through the connecting pipe, realizing the dust suppression function, reducing the possibility of dust mixed in the asphalt, and thus improving the quality of road paving.

[0018] Preferably, the connecting assembly includes a control rod, one end of which is connected to a control base and the other end of which is connected to a control board, and the rotation axes of the control rod, the control base, and the control board are on the same straight line.

[0019] By adopting the above technical solution, when the control plate rotates, it drives the control rod to rotate, which in turn drives the control seat to rotate. At this time, the operator can adjust the frequency of the piston block's reciprocating movement according to the asphalt output, thereby adjusting the water delivery frequency of the pumping unit to adapt it to different road surface requirements. Simultaneously, the control rod, control seat, and control plate, with their rotation axes aligned on the same straight line, improve the accuracy of controlling the water delivery frequency of the pumping unit, ensuring more stable transmission between the first and second control bevel gears.

[0020] Preferably, the cleaning assembly includes a dust collection box and several vacuum cleaners. The dust collection box is mounted on the vehicle frame and is connected to a connecting pipe. The several vacuum cleaners are evenly arranged on the side of the vehicle frame away from the dust collection box, and each vacuum cleaner is connected to the dust collection box through a dust collection pipe.

[0021] By adopting the above technical solution, when asphalt needs to be laid on the road surface, the operator starts each vacuum cleaner. The vacuum cleaner draws the impurities from the road surface into the dust collection pipe. The impurities enter the dust collection box through the dust collection pipe. At this time, the water pump sprays water to reduce dust on the impurities entering the dust collection box. On the one hand, it achieves the function of cleaning the road surface, and on the other hand, it reduces the possibility of impurities mixed in the asphalt, thereby improving the paving quality of the road surface.

[0022] Preferably, a connecting groove is provided on the side of the frame away from the dust collection box, and a connecting plate is slidably connected in the connecting groove. Several vacuum cleaners are evenly arranged on the side of the connecting plate away from the frame. A buffer groove is provided on the side of the connecting plate away from the frame, and a scraper is slidably connected in the buffer groove. A connecting spring is provided in the buffer groove, one end of which is connected to the bottom of the buffer groove and the other end is connected to the scraper. The connecting plate is connected to the control board through a synchronization component.

[0023] By adopting the above technical solution, when the operator lays asphalt on the road surface, the vehicle frame moves, driving the connecting plate to move as well. The connecting plate then drives each vacuum cleaner to move, and the vacuum cleaners remove impurities from the road surface. Asphalt flows out through the discharge port, and the scraper contacts the asphalt, thus achieving the function of laying asphalt. At this time, under the elastic force of the connecting spring, the scraper makes relatively stable contact with the asphalt, further improving the paving quality. Moreover, when the operator adjusts the asphalt discharge rate, the control plate drives the synchronization component to start, which can then adjust the position of the connecting plate so that the scraper and each vacuum cleaner can be adapted to road surfaces with different construction requirements.

[0024] Preferably, the synchronization assembly includes a synchronization column, a synchronization rod, and a synchronization disc. The synchronization column is connected to a control board, and the rotation axes of the synchronization column and the control board are on the same straight line. A clearance hole is provided on the frame in the vertical direction, and the synchronization column is rotatably connected in the clearance hole. A synchronization groove is provided in the vertical direction at the end of the synchronization column away from the frame. The synchronization rod is threaded to the inner wall of the synchronization groove. A limiting strip is provided on the synchronization rod. A limiting groove is provided on the inner wall of the clearance groove, and the limiting strip is slidably connected in the limiting groove. The synchronization disc is coaxially disposed at the end of the synchronization rod away from the frame. A limiting cavity is provided on the connecting plate, and the synchronization disc is disposed in the limiting cavity. A control groove communicating with the limiting cavity is provided on the connecting plate, and the synchronization rod is disposed in the control groove.

[0025] By adopting the above technical solution, when the control plate rotates, the control plate drives the synchronous column to rotate. Under the limiting action of the limiting groove, the synchronous rod moves away from the vehicle frame. The synchronous rod then drives the synchronous disc to move away from the vehicle frame. The synchronous disc then drives the connecting plate to move away from the vehicle frame, so as to complete the adjustment of the position of the scraper and each vacuum cleaner, so that the scraper and each vacuum cleaner are matched with the output of asphalt.

[0026] This application also discloses an asphalt paving method for a municipal road asphalt paving device, comprising the following steps:

[0027] An asphalt paving method using a municipal road asphalt paving device includes the following steps:

[0028] The flow control component is activated to control the output of asphalt;

[0029] The connecting component drives the speed change component to start, and the speed change component controls the water delivery frequency of the pumping component.

[0030] The speed control component controls the start of the synchronization component, and the synchronization component controls the movement of the cleaning component and the scraper to adapt to different road surfaces with different construction requirements.

[0031] The cleaning component is activated, and it sucks up impurities from the road surface;

[0032] The drive assembly is started, which drives the mixing assembly and the water pumping component to start. The mixing assembly mixes the asphalt, and the water pumping component draws out clean water and delivers it to the cleaning assembly.

[0033] By adopting the above technical solution, when road paving is required, the operator first puts asphalt into the storage tank, starts the drive assembly, and drives the mixing assembly to start. The mixing assembly mixes the asphalt, making it less prone to solidification. The operator then rotates the control panel according to the construction requirements to change the asphalt output. While the control panel rotates, the synchronization assembly starts and changes the position of the connecting plate, thereby changing the position of the scraper and each vacuum cleaner. At the same time, the control panel adjusts the position of the speed change assembly, which changes the water delivery frequency of the pumping unit. The drive assembly then provides power to the pumping unit through the speed change assembly. At this time, the pumping unit can deliver clean water to the cleaning assembly, thus providing convenience for the pumping unit to adapt to road surfaces with different construction requirements.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By setting up a pumping unit, a speed-changing component, and a quantity control component, the speed-changing component changes the water delivery frequency of the pumping unit when controlling the asphalt output, so that the pumping unit can adapt to different construction requirements. Under the action of the pumping unit, the possibility of impurities on the road surface falling into the asphalt is reduced, thereby improving the paving quality of the road.

[0036] 2. By setting up a scraper, when the vehicle frame moves, the frame drives the connecting plate and the scraper to move. The scraper contacts the asphalt and lays the asphalt, thus facilitating the laying of asphalt.

[0037] 3. By setting up a synchronization component, when the operator adjusts the asphalt discharge rate, the synchronization component adjusts the position of the connecting plate synchronously, so that the cleaning component and scraper can be adapted to different construction requirements.

[0046] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0047] This application discloses an asphalt paving device for municipal roads. (Refer to...) Figure 1A municipal road asphalt paving device includes a frame 1. Along its length, the frame 1 is sequentially equipped with a cleaning component 2, a dust suppression component 3, and a storage tank 4. The cleaning component 2 and the dust suppression component 3 are connected. The storage tank 4 stores asphalt and contains a mixing component 41 for mixing the asphalt.

The frame 1 is equipped with a speed control component 5 for controlling the water delivery frequency of the water pump 32. The speed control component 5 is connected to the drive component 11 and also connected to the quantity control component 42 via a connecting component.

[0048] When operators need to pave the road surface, they first put asphalt into storage tank 4, then start drive assembly 11. Drive assembly 11 controls the mixing assembly 41 to start, preventing the asphalt from solidifying. The operator then controls the flow control assembly 42 according to construction requirements to change the asphalt output. At this point, the operator can control the movement of the vehicle frame 1 to pave the asphalt. Cleaning assembly 2 then cleans impurities from the road surface. Under the action of the connecting assembly, transmission assembly 5 starts and changes the water delivery efficiency of pumping unit 32 to adapt to different construction requirements. After pumping unit 32 delivers clean water to cleaning assembly 2, the clean water comes into contact with impurities and settles them, preventing impurities from drifting and mixing into the asphalt, thereby improving the quality of the pavement.

[0049] Reference Figure 1 The stirring assembly 41 includes a stirring shaft 411 and a stirring blade 412. The stirring shaft 411 is rotatably connected to the storage tank 4, and the stirring blade 412 is spirally arranged on the stirring shaft 411.

[0050] The drive assembly 11 includes a motor 111, a first drive bevel gear 112, a second drive bevel gear 113, and a transmission component 114. The motor 111 is fixed to the frame 1.

The first pulley 424 cooperates with the first measurement control plate 421, and the second pulley 425 cooperates with the second measurement control plate 422. A first pull rope 426 is connected to the first measurement control plate 421. The first pull rope 426 is wound around the first pulley 424 and fixed to one end of the control plate 423. A second pull rope 427 is connected to the second measurement control plate 422. The second pull rope 427 is wound around the second pulley 425 and fixed to the other end of the control plate 423. The control plate 423 is connected to the connecting assembly.

[0052] Reference Figure 2 and Figure 3 The pumping component 32 includes a transfer pipe 321 and a piston block 322. The transfer pipe 321 is connected to the connecting pipe 33, and the piston block 322 is slidably connected in the transfer pipe 321. The piston block 322 is connected to the transmission assembly 5 through a control component 34.

[0053] The control component 34 includes a drive disc 341, a transition bevel gear 342, and a connecting rod 343. The drive disc 341 is rotatably connected to the frame 1. The transition bevel gear 342 is coaxially fixed on the shaft of the drive disc 341 and engages with the transmission assembly 5. The connecting rod 343 is rotatably connected to the side of the drive disc 341 away from the transition bevel gear 342, and is eccentrically positioned on the drive disc 341. The end of the connecting rod 343 away from the drive disc 341 is hinged to the piston block 322.

[0054] Reference Figure 2 and Figure 3 The transmission assembly 5 includes a control base 51, a first rotating shaft 52, and a second rotating shaft 53. Both the first rotating shaft 52 and the second rotating shaft 53 are rotatably connected to the control base 51, and are offset from each other. A first control bevel gear 521 is coaxially fixed to both ends of the first rotating shaft 52, and a second control bevel gear 531 is coaxially fixed to both ends of the second rotating shaft 53. The first control bevel gear 521 and the second control bevel gear 531 near the second transmission bevel gear 118 both engage with the second transmission bevel gear 118, and the first control bevel gear 521 and the second control bevel gear 531 near the adapter bevel gear 342 both engage with the adapter bevel gear 342. The diameter of the first control bevel gear 521 is d1, and the diameter of the second control bevel gear 531 is d2. <d2。

[0055] The connecting assembly includes a control lever 13, one end of which is fixed to the control plate 423 and the other end of which is fixed to the control base 51. The rotation axes of the control plate 423, the control base 51 and the control lever 13 are on the same straight line.

[0056] When the road surface needs to be paved, the operator puts the asphalt into the storage bucket 4 and then starts the motor 111. The motor 111 controls the first drive bevel gear 112 to rotate, the first drive bevel gear 112 controls the second drive bevel gear 113 to rotate, and the second drive bevel gear 113 drives the stirring shaft 411 and the stirring blade 412 to rotate. The stirring blade 412 stirs the asphalt, making it less likely for the asphalt to solidify. In addition, the storage bucket 4 is equipped with an electric heating wire (not shown in the figure), which heats the asphalt in the storage bucket 4, further reducing the possibility of the asphalt solidifying.

[0057] After the operator moves the vehicle frame 1 to the construction position, the operator rotates the control lever 13 according to the construction requirements. The control lever 13 drives the control plate 423 to rotate, and the control plate 423 simultaneously pulls the first pull rope 426 and the second pull rope 427. The first pull rope 426 drives the first pulley 424 to rotate, and the second pull rope 427 drives the second pulley 425 to rotate. Under the action of the first pulley 424 and the second pulley 425, the prestress inside the first pull rope 426 and the second pull rope 427 is increased, reducing the possibility of breakage of the first pull rope 426 and the second pull rope 427. The first pull rope 426 then drives the first control plate 421 to move, and the second pull rope 427 then drives the second control plate 422 to move, so that the asphalt can fall from the discharge port 12. At this time, the second transmission bevel gear 118 and the transition bevel gear 342 mesh with the corresponding second control bevel gear 531, respectively.

[0058] The second drive bevel gear 113 drives the first transmission bevel gear 115 and the support shaft 431 to rotate. The support shaft 431 drives the first gear 116 to rotate. Under the transmission action of the transmission belt 119, the first gear 116 drives the second gear 117 to rotate. The second gear 117 then drives the second transmission bevel gear 118 to rotate. The second transmission bevel gear 118 drives the corresponding second control bevel gear 531 to rotate. The second control bevel gear 531 drives a corresponding second control bevel gear 531 to rotate. The second control bevel gear 531 can then drive the adapter bevel gear 342 to rotate. The bevel gear 342 drives the drive disc 341 to rotate, and the drive disc 341 drives the connecting rod 343 to rotate. Under the limiting action of the transfer pipe 321 and the action of the eccentrically set connecting rod 343, the connecting rod 343 drives the piston block 322 to move back and forth in the transfer pipe 321. At this time, the piston block 322 first draws water from the piston block 322 and then transports the water to the cleaning component 2 so as to settle the impurities absorbed by the cleaning component 2, so that the impurities are less likely to fall and mix into the asphalt, thereby improving the final paving quality of the road surface.

The cleaning assembly 2 includes a dust collection box 21 and several vacuum cleaners 22. The dust collection box 21 is fixed on the frame 1, and the several vacuum cleaners 22 are evenly arranged on the side of the connecting plate 15 away from the frame 1.

The synchronization column 61 is fixed to the control plate 423, and the rotation axis of the synchronization column 61 is collinear with the rotation axis of the control plate 423. A clearance hole 16 is provided on the frame 1 in the vertical direction, and the synchronization column 61 is rotatably connected in the clearance hole 16. A synchronization groove 611 is provided in the vertical direction at the end of the synchronization column 61 away from the frame 1, and the synchronization rod 62 is threadedly connected in the synchronization groove 611.

The synchronizing rod 62 extends into the limiting cavity 154 and is fixed to the synchronizing disk 63.

[0062] When the operator rotates the control plate 423, the control plate 423 drives the synchronous column 61 to rotate. Under the limiting action of the limiting strip 621 and the limiting groove 161, the synchronous rod 62 moves along the axial direction of the clearance hole 16. The synchronous rod 62 then drives the synchronous disc 63 to move, and the synchronous disc 63 then drives the connecting plate 15 to move along the limit of the connecting groove 14. At this time, under the action of the synchronous disc 63 and the limiting cavity 154, the connection stability between the synchronous rod 62 and the connecting plate 15 is improved, so that the synchronous rod 62 can control the movement of the connecting plate 15 more stably. The connecting plate 15 then drives the scraper 152 and each vacuum cleaner 22 to move. At this time, the scraper 152 and each vacuum cleaner 22 can move to the designated position according to different construction requirements. After the operator adjusts the asphalt output, the operator controls the vehicle frame 1 to move. Each vacuum cleaner 22 cleans impurities from the road surface and transports them to the dust collection box 21 via the dust collection pipe 23. The connecting pipe 33 then transports clean water to the dust collection box 21 to settle the impurities, reducing the possibility of impurities becoming mixed into the asphalt and thus improving the road paving quality. As the vehicle frame 1 moves, the scraper 152 contacts the asphalt to perform the function of paving. At this time, under the elastic force of the connecting spring 153, the scraper 152 is stably pressed against the asphalt, further improving the road paving quality.

[0063] Reference Figure 5 and Figure 6The first control plate 421 and the second control plate 422 are both connected to the inner wall of the storage bucket 4 by a return spring 428. When the asphalt thickness of the road surface needs to be changed, the operator rotates the control lever 13 in the opposite direction. Under the elastic force of the return spring 428, the first control plate 421 and the second control plate 422 move in opposite directions to reduce the amount of asphalt discharged. At the same time, the connecting plate 15 moves away from the frame 1, so that the scraper 152 and each vacuum cleaner 22 are closer to the ground. When the second transmission bevel gear 118 and the transition bevel gear 342 mesh with the corresponding first control bevel gear 521, since the diameter of the first transmission bevel gear 115 is smaller than the diameter of the second transmission bevel gear 118, the rotation speed of the transition bevel gear 342 is increased, and the frequency of the reciprocating movement of the piston block 322 is increased. This makes it easier for the connecting pipe 33 to send more clean water into the dust collection box 21, improving the efficiency of removing impurities and increasing the overall applicability of the paving device.

[0064] Reference Figure 1 To reduce the possibility of the control lever 13 rotating during the movement of the frame 1, two opposing fixing plates 7 are slidably connected to the frame 1. The two opposing fixing plates 7 are connected by a double-acting screw 71, and the two fixing plates 7 are threaded onto the two threaded sections of the double-acting screw 71. After the operator rotates the control lever 13, the operator rotates the double-acting screw 71, which simultaneously moves the two fixing plates 7. After the two fixing plates 7 clamp the control lever 13, the control lever 13 is limited, so that the laying device can work more stably.

[0065] Reference Figure 1 and Figure 7 To reduce the backflow of clean water, two opposing baffles 8 are rotatably connected at the connection between the connecting pipe 33 and the dust collection box 21. The two opposing baffles 8 abut against each other, and a torsion spring 81 is wound around the rotating shaft of the two opposing baffles 8. When the piston block 322 pumps water, the two baffles 8 abut against each other and seal the connecting pipe 33 and the dust collection box 21. This prevents backflow of clean water and reduces the possibility of impurities entering and clogging the connecting pipe 33. When the piston block 322 squeezes and delivers clean water to the dust collection box 21, the two opposing baffles 8 rotate away from the connecting pipe 33 to allow clean water to enter the dust collection box 21. After the clean water delivery is complete, the two baffles 8 return to their original position under the restoring force of the torsion spring 81, so that the baffles 8 continue to seal the connecting pipe 33 and the dust collection box 21.

[0066] The implementation principle of this application embodiment is as follows: When asphalt needs to be laid on the road surface, the operator uses the quantity control component 42 to adjust the subsequent asphalt output. Under the action of the connecting component, the transmission component 5 starts synchronously and adjusts the water delivery frequency of the water pumping component 32. At the same time, under the action of the synchronization component 6, the connecting plate 15 moves and changes the distance between the scraper 152 and the cleaning component 2 and the ground. The operator then moves the vehicle frame 1 to the designated position, starts the drive component 11, and puts the asphalt into the storage tank 4. The drive component 11 drives the mixing component 41 to start, and the drive component 11 drives the water pumping component 32 to start through the transmission component 5. The cleaning component 2 extracts impurities from the ground, and the water pumping component 32 delivers clean water to the cleaning component 2. The clean water settles the impurities, making it less likely for them to fall into the asphalt, thereby improving the final paving quality of the road surface.

[0067] This application also discloses an asphalt paving method for a municipal road asphalt paving device, comprising the following steps:

[0068] Activate the flow control component 42 to control the asphalt discharge rate;

[0069] The volume control component 42 controls the start of the synchronization component 6, and the synchronization component 6 adjusts the distance between the cleaning component 2 and the scraper 152 and the ground;

[0070] The flow control component 42 synchronously controls the speed change component 5 to start under the action of the connecting component, and the speed change component 5 changes the water delivery frequency of the pumping component 32.

[0071] Start drive assembly 11, drive assembly 11 controls the start of mixing assembly 41, mixing assembly 41 mixes asphalt;

[0072] Drive component 11 controls pumping component 32 to start under the action of speed change component 5. Pumping component 32 delivers clean water to cleaning component 2 to settle impurities.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
