[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 4 , the present invention details the above technical solutions through the following embodiments:

[0025] A highway asphalt flattening device includes: a frame 1; a pressing roller 2 is arranged inside the frame 1, circular sealing plates 3 are fixedly connected to both sides inside the pressing roller 2, hollow tubes 4 are fixedly connected to the centers of the circular sealing plates 3, and the ends of the hollow tubes 4 far from the circular sealing plates 3 are rotatably connected to the frame 1. A first rotating shaft 5 is arranged at the center of the pressing roller 2, and both ends of the first rotating shaft 5 are rotatably connected to the hollow tubes 4. A motor 6 is fixedly connected to one side of the frame 1, and one end of the first rotating shaft 5 is fixedly connected to the output end of the motor 6; a vibration mechanism 7 for improving the flattening effect is arranged on the outer surface of the first rotating shaft 5 inside the pressing roller 2; a connecting mechanism 8 for quickly docking with a trailer is arranged on one side of the frame 1. The user docks the flattening device with the trailer through the connecting mechanism 8. While the trailer drags the flattening device, the motor 6 is started. The output end of the motor 6 drives the first rotating shaft 5, and the first rotating shaft 5 drives the vibration mechanism 7 inside the pressing roller 2 to generate high-frequency vibrations, so that the pressing roller 2 vibrates and flattens the asphalt. It can make the pressing roller 2 generate high-frequency vibrations by itself and cooperate with the weight of the device itself to press the asphalt into sheets, solving the problem that the original pressing device completely flattens the asphalt by its own weight, resulting in inconvenient movement when the self-weight of the device is too large, and poor asphalt flattening effect when the self-weight is too small, and low practicability.

[0026] Such as Figure 2 And Figure 3As shown in the figure, the vibration mechanism 7 includes: on the outer surface of the first rotating shaft 5 located inside the pressure roller 2, a fixed plate 9 is rotatably connected. The fixed plates 9 are fixedly connected to the pressure roller 2. Between the two fixed plates 9, first gears 10 are arranged. The first gears 10 are fixedly arranged on the outer surface of the first rotating shaft 5. On one side of each first gear 10, a second gear 11 is meshed. The centers of the second gears 11 are fixedly connected to second rotating shafts 12. Both ends of the second rotating shafts 12 penetrate through the fixed plates 9 and extend to the first eccentric blocks 13. The first eccentric blocks 13 are fixedly connected to the second rotating shafts 12. The second rotating shafts 12 are rotatably connected to the fixed plates 9. On one side of each first gear 10, a first synchronous pulley 14 is arranged. The first synchronous pulleys 14 are fixedly arranged on the outer surface of the first rotating shaft 5. The first synchronous pulleys 14 are connected to second synchronous pulleys 16 through synchronous belts 15. The centers of the second synchronous pulleys 16 are fixedly connected to third rotating shafts 17. Both ends of the third rotating shafts 17 penetrate through the fixed plates 9 and extend to the second eccentric blocks 18. The second eccentric blocks 18 are fixedly connected to the third rotating shafts 17 respectively. The third rotating shafts 17 are rotatably connected to the fixed plates 9. When the first rotating shaft 5 rotates, it drives the first gears 10 and the first synchronous pulleys 14. The first gears 10 drive the second gears 11. The second gears 11 drive the second rotating shafts 12. The second rotating shafts 12 drive the first eccentric blocks 13 to rotate. At the same time, the first synchronous pulleys 14 drive the third rotating shafts 17 through the synchronous belts 15. The third rotating shafts 17 drive the second eccentric blocks 18 to rotate. When the first eccentric blocks 13 and the second eccentric blocks 18 rotate, high-frequency vibrations are generated, thereby causing the pressure roller 2 to generate high-frequency vibrations.

[0027] As Figure 1 shown in the figure, the connecting mechanism 8 includes: on one side of the frame 1, a Y-shaped connecting frame 19 is fixedly connected. On the side of the Y-shaped connecting frame 19 away from the frame 1, there are two couplers 20. The two couplers 20 cooperate with each other. One of the couplers 20 is fixedly connected to the Y-shaped connecting frame 19, and the other coupler 20 is fixedly connected to the trailer. The user fixes the two couplers 20 to the trailer and the flattening device respectively. When the trailer and the flattening device approach each other, the two couplers 20 are connected to each other. Thus, when the flattening device and the trailer approach each other, the flattening device and the trailer can be automatically docked, simplifying the docking process of the flattening device and the trailer and improving work efficiency.

[0028] As Figure 4As shown in the figure, the coupler 20 includes a housing 21, a bolt 22, a semi-circular ring 23, a self-locking plate 24, and an unlocking lever 25. One side of the housing 21 is fixedly connected to the bolt 22. Near the bolt 22 on the housing 21, a semi-circular ring 23 is fixedly connected. Inside the semi-circular ring 23, a self-locking plate 24 that fits is provided. An unlocking lever 25 is fixedly connected to the arc surface of the self-locking plate 24. One end of the unlocking lever 25 away from the self-locking plate 24 penetrates through the semi-circular ring 23 and the housing 21 and extends to the outside of the housing 21. When the two couplers 20 approach each other, the two bolts 22 are respectively inserted into the inside of the housing 21 of the other party. At the same time, the two self-locking plates 24 are mutually extruded through the cooperation of the inclined surfaces, causing the two self-locking plates 24 to respectively rotate within the semi-circular ring 23. When the two semi-circular rings 23 are connected, the unlocking lever 25 pulls the self-locking plate 24 to reset, and then the two couplers 20 can be mutually connected.

[0029] As Figure 4 shown, a spring 26 is fixedly connected to the middle section of the unlocking lever 25. One end of the spring 26 away from the unlocking lever 25 is fixedly connected to the housing 21. When the two semi-circular rings 23 are connected, the spring 26 can pull the unlocking lever 25 through the cooperation of the housing 21, causing the unlocking lever 25 to drive the self-locking plate 24 to reset.

[0030] As Figure 1 and Figure 2 shown, fourth rotating shafts 27 are provided on both sides of the pressing roller 2. Both ends of the fourth rotating shafts 27 are rotatably connected to the frame 1. On the outer surface of the fourth rotating shafts 27 located inside the frame 1, spiral blades 28 are fixedly connected. The spiral blades 28 cooperate with the pressing roller 2. While the trailer drags the flattening device, the pressing roller 2 rotates inside the frame 1 through the cooperation of the circular sealing plate 3 and the hollow tube 4. While the hollow tube 4 rotates, it drives the fourth rotating shafts 27 to rotate. While the fourth rotating shafts 27 rotate, they drive the spiral blades 28. While the spiral blades 28 rotate, they can scrape off the impurities adhering to the surface of the pressing roller 2, thereby achieving the purpose of cleaning the pressing roller 2.

[0031] As Figure 1 and Figure 2 shown, one end of each of the two fourth rotating shafts 27 penetrates through the frame 1 and extends to the third gear 29. The third gears 29 are respectively fixedly connected to the fourth rotating shafts 27. Both of the two third gears 29 are meshed with the fourth gear 30. The fourth gear 30 is fixed to the outer surface of the hollow tube 4. While the hollow tube 4 rotates, it drives the fourth gear 30. The fourth gear 30 drives the third gear 29, and the fourth gear 30 drives the fourth rotating shafts 27.

[0032] Working principle: When the trailer drags the flattening device, the motor 6 is started at the same time. The output end of the motor 6 drives the first rotating shaft 5. While the first rotating shaft 5 rotates, it drives the first gear 10 and the first synchronous pulley 14. The first gear 10 drives the second gear 11, the second gear 11 drives the second rotating shaft 12, and the second rotating shaft 12 drives the first eccentric block 13 to rotate. At the same time, the first synchronous pulley 14 drives the third rotating shaft 17 through the synchronous belt 15, and the third rotating shaft 17 drives the second eccentric block 18 to rotate. When the first eccentric block 13 and the second eccentric block 18 rotate, high-frequency vibrations are generated, thereby causing the pressure roller 2 to generate high-frequency vibrations. And the pressure roller 2 rotates inside the frame 1 through the cooperation of the circular sealing plate 3 and the hollow tube 4. While the hollow tube 4 rotates, it drives the fourth gear 30, the fourth gear 30 drives the third gear 29, the fourth gear 30 drives the fourth rotating shaft 27, and while the fourth rotating shaft 27 rotates, it drives the auger blade 28. While the auger blade 28 rotates, it can scrape off the impurities adhering to the surface of the pressure roller 2, thereby achieving the purpose of cleaning the pressure roller 2.

[0033] The user fixes the two couplers 20 to the trailer and the flattening device respectively. When the trailer and the flattening device approach each other, the two pins 22 are respectively inserted into the inner parts of the shells 21 of each other. At the same time, the two self-locking plates 24 are mutually extruded through the cooperation of the inclined surfaces, so that the two self-locking plates 24 respectively rotate inside the semi-circular rings 23. When the two semi-circular rings 23 are connected, the spring 26 pulls the unlocking rod 25 through the cooperation of the shell 21, so that the unlocking rod 25 drives the self-locking plate 24 to reset, and then the two couplers 20 are connected to each other.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
