[0056] Example 1

[0057] Reference Figure 1-Figure 7 A composite surface layer asphalt pavement construction device of the present embodiment includes an equipment box 1, a stirring mechanism, a turning mechanism and a compacting mechanism. A plurality of wheels are symmetrically installed at the bottom of the equipment box 1. A traction frame 2 is fixedly installed at the bottom of one side of the equipment box 1. The stirring mechanism is installed in the equipment box 1. The stirring mechanism is used to mix and stir asphalt and gravel. The turning mechanism is installed at the top of one side of the equipment box 1. One side of the turning mechanism extends into the equipment box 1 and is connected to the stirring mechanism. The turning mechanism is used to drive the stirring mechanism to turn over and pour out the mixed asphalt and gravel. The compacting mechanism is installed at the bottom of the other side of the equipment box 1. The compacting mechanism is used to compact the asphalt and gravel laid on the road surface. One side of the compacting mechanism extends into the equipment box 1 and is connected to the turning mechanism. The compacting mechanism is respectively connected to the inner walls on both sides of the equipment box 1.

[0058] Reference Figure 5 and Figure 6 The mixing mechanism is as follows: two rotating shafts 9 are rotatably connected to the inner walls of the equipment box 1 on both sides, and are connected to the flip mechanism. The ends of the two rotating shafts 9 close to each other are fixedly installed with the same mixing box 10, which is used to contain sand and asphalt to be mixed.

[0059] A stirring motor 11 is fixedly installed on the top of one side of the stirring box 10, and the output shaft of the stirring motor 11 extends into the stirring box 10. A reciprocating screw 12 is fixedly installed, and one end of the reciprocating screw 12 is rotatably connected to the inner wall of one side of the stirring box 10 to ensure that it can rotate stably.

[0060] A stirring frame 13 is also connected to the stirring box 10 in a transverse sliding manner. A nut 14 is fixedly installed on the top of one side of the stirring frame 13. The reciprocating screw 12 passes through the stirring frame 13 and the nut 14 respectively, and is threadedly connected to the nut 14. This design enables the stirring frame 13 to slide transversely along the inner wall of the stirring box 10 through the threaded transmission action with the nut 14 when the reciprocating screw 12 rotates.

[0061] In actual use, first put sand and asphalt into the mixing box 10, then start the mixing motor 11 to drive the reciprocating screw 12 to rotate, and under the threaded transmission action of the nut 14 and the reciprocating screw 12, the mixing frame 13 begins to slide laterally along the inner wall of the mixing box 10 to mix and stir the sand and asphalt, so that the asphalt and sand can be evenly mixed together.

[0062] In addition, a heat insulation cover 15 is fixedly installed on the mixing box 10, and a plurality of electric heating rods 16 are fixedly installed at equal intervals on the inner wall of the heat insulation cover 15. The electric heating rods 16 are used to heat the mixing box 10. When the plurality of electric heating rods 16 need to be energized, they will heat the mixing box 10 and keep the mixing box 10 in a high temperature state. In this way, when the asphalt and sand and gravel are mixed and stirred, the asphalt can be prevented from solidifying, so that it can be fully mixed with the sand and gravel.

[0063] Reference Figure 1 and Figure 4 , Flipping mechanism: The mounting frame 17 is fixedly installed on the top of one side of the equipment box 1, and is used to support and fix other components. In the mounting frame 17, the transmission shaft 18 is rotatably connected so that it can rotate freely. Two through holes are symmetrically opened on the inner wall of one side of the equipment box 1 to allow the belt assembly to pass through and connect with the rotating shaft 9.

[0064] Two belt assemblies are symmetrically installed on the transmission shaft 18, and each belt assembly includes two synchronous wheels 19 and a synchronous belt 20. The synchronous wheels 19 are fixedly mounted on the transmission shaft 18 and the rotating shaft 9 respectively, and the synchronous belt 20 is transmission-connected between the two synchronous wheels 19. In this way, when the transmission shaft 18 rotates, the rotating shaft 9 can be driven to rotate through the transmission cooperation of the synchronous wheels 19 and the synchronous belt 20.

[0065] In addition, the two synchronous belts 20 are also connected to the compacting mechanism. When the synchronous belts 20 move, they can not only drive the rotating shaft 9 to rotate, but also drive the compacting mechanism to move.

[0066] At the bottom of the mounting frame 17, a power assembly is installed to provide rotational power. The power assembly includes a stepper motor 21, whose output shaft extends into the mounting frame 17 and is fixedly mounted with an active bevel gear 22. A driven bevel gear 23 is fixedly sleeved on the transmission shaft 18. The active bevel gear 22 is meshed with the driven bevel gear 23. Therefore, when the stepper motor 21 is started, it will drive the active bevel gear 22 to rotate, and then drive the transmission shaft 18 to rotate through the meshing transmission with the driven bevel gear 23.

[0067] In actual use, the stepper motor 21 is started, and the transmission shaft 18 is driven to rotate through the meshing transmission of the active bevel gear 22 and the driven bevel gear 23. The rotation of the transmission shaft 18 is driven by the transmission cooperation of the synchronous wheel 19 and the synchronous belt 20 to drive the two rotating shafts 9 to rotate. Since the rotating shaft 9 is connected to the mixing box 10, the mixing box 10 will flip over accordingly. When the mixing box 10 flips 180°, its opening faces downward. At this time, the mixed asphalt and sand and gravel can be poured into the conveying mechanism. At the same time, when the synchronous belt 20 moves, it will also drive the compacting mechanism to move so as to compact the poured asphalt and sand and gravel.

[0068] Reference Figure 2 and Figure 4The compacting mechanism includes a support plate 32 fixedly mounted on the bottom of the other side of the equipment box 1, a material discharge port is provided on the support plate 32, a guide plate 33 passes through the material discharge port, a scraper 34 is fixedly mounted on the bottom of the support plate 32, a moving hole is provided on the support plate 32, a support frame 36 corresponding to the moving hole is fixedly mounted on the top of the support plate 32, a fixed frame is slidably connected in the support frame 36, a pressure roller 37 is rotatably connected in the fixed frame, and the pressure roller 37 is used to compact the asphalt and gravel of the repaired road surface, and two L-shaped mounting rods 35 are symmetrically fixedly mounted on the top of the fixed frame, and the top ends of the two L-shaped mounting rods 35 extend into the equipment box 1 and are fixedly mounted with the same connecting plate 29, and one end of the connecting plate 29 Two slide plates 30 are symmetrically fixedly installed on the sides, and concave slide rails 31 are fixedly installed on the inner walls of both sides of the equipment box 1. One side of the slide plate 30 extends into the corresponding concave slide rail 31 and is slidably connected to the inner wall of the concave slide rail 31. Two transmission components are symmetrically installed on the connecting plate 29. The two transmission components are respectively connected to the inner walls of both sides of the equipment box 1. The two transmission components are respectively connected to the corresponding synchronous belts 20. After the two transmission components receive the driving force of the corresponding synchronous belts 20, they can move, thereby driving the connecting plate 29 to move longitudinally. When the connecting plate 29 moves downward, the fixed frame can be driven downward through the two L-shaped mounting rods 35, thereby driving the pressure roller 3 7 moves downward and moves the pressure roller 37 to the bottom of the support plate 32. At this time, when the equipment box 1 moves and drives the pressure roller 37 to move, the scraper 34 can be driven to move to level the asphalt and gravel laid on the road surface that needs to be repaired, and when the pressure roller 37 passes, the paved asphalt and gravel can be compacted, so that when the road surface is repaired, targeted compaction can be carried out without causing damage to the undamaged road surface. The transmission assembly includes a limit plate 25 fixedly mounted on the inner wall of the equipment box 1, and a transmission rack 24 is slidably connected to the limit plate 25. One end of the transmission rack 24 is fixedly connected to the corresponding synchronous belt 20. The driving gear 26, the transmission rack 24 is meshed with the transmission gear 26, and a connecting shaft 27 is fixedly installed at an eccentric position on one side of the transmission gear 26. One end of the connecting shaft 27 is rotatably connected to a transmission rod 28, and the transmission rod 28 passes through a connecting plate 29 and is slidably connected to the connecting plate 29. When the transmission rack 24 moves laterally with the synchronous belt 20, it can drive the transmission gear 26 to rotate under the meshing transmission action with the transmission gear 26. At this time, it can drive the connecting shaft 27 to move in a longitudinal arc shape, that is, it can drive the transmission rod 28 to move. At this time, under the sliding cooperation of the transmission rod 28 and the connecting plate 29, it can drive the connecting plate 29 to move longitudinally, and the height of the pressure roller 37 can be adjusted.

[0069] Example 2

[0070] refer to Figure 8 and Fig. 9 Based on the first embodiment, this embodiment further proposes a conveying mechanism for the composite surface layer asphalt pavement construction device proposed in the first embodiment. The conveying mechanism is installed in the equipment box 1, and the conveying mechanism is used to output the mixed asphalt and sand and gravel.

[0071] refer to Figure 8 and Fig. 9 , Compacting mechanism: A support plate 32 is fixedly installed at the bottom of the other side of the equipment box 1, a feed opening is opened on the support plate 32, and a guide plate 33 is set to pass through the feed opening, and a scraper 34 is fixedly installed at the bottom of the support plate 32 for subsequent leveling of asphalt and sand and gravel. At the same time, a moving hole is opened on the support plate 32, and a support frame 36 corresponding to the moving hole is fixedly installed on the top thereof.

[0072] A fixed frame is slidably connected inside the support frame 36, and a pressure roller 37 is rotatably connected inside the fixed frame. The pressure roller 37 is designed to compact the asphalt and gravel of the repaired road surface. In order to ensure the stable movement of the pressure roller 37, two L-shaped mounting rods 35 are symmetrically fixedly installed on the top of the fixed frame. The top ends of the two L-shaped mounting rods 35 extend into the equipment box 1 and are fixedly installed on the same connecting plate 29.

[0073] Two slide plates 30 are symmetrically fixedly installed on one side of the connecting plate 29, and concave slide rails 31 are fixedly installed on the inner walls of both sides of the equipment box 1. One side of the slide plate 30 extends into the corresponding concave slide rail 31 and is slidably connected to the inner wall of the concave slide rail 31. This design enables the connecting plate 29 to move longitudinally in the equipment box 1.

[0074] Two transmission components are symmetrically installed on the connecting plate 29. The two transmission components are respectively connected to the inner walls on both sides of the equipment box 1 and are connected to the corresponding synchronous belt 20. When the two transmission components receive the driving force of the corresponding synchronous belt 20, they will move, thereby driving the connecting plate 29 to move longitudinally.

[0075] In actual use, when the connecting plate 29 moves downward, the two L-shaped mounting rods 35 will drive the fixing frame to move downward, and then drive the pressure roller 37 to move downward until the pressure roller 37 moves to the bottom of the support plate 32. At this time, when the equipment box 1 moves and drives the pressure roller 37 to move, the scraper 34 will also move accordingly. In this way, the scraper 34 can level the asphalt and gravel laid on the road surface that needs to be repaired, and when the pressure roller 37 passes, it will compact the spread asphalt and gravel. This design enables targeted compaction when repairing the road surface without causing damage to the undamaged road surface.

[0079] S3, energizing the plurality of electric heating rods 16 to heat the mixing box 10, so that the mixing box 10 is in a high temperature state, and at this time, when the asphalt and the gravel are mixed and stirred, the asphalt can be prevented from solidifying, so that it can be fully mixed with the gravel;

[0080] S4, after the asphalt and gravel are mixed, the stepper motor 21 can be started to drive the mixing box 10 to flip downward 180 degrees, so that the mixed asphalt and gravel can be poured onto the conveyor belt 8;

[0081] S5. When the synchronous belt 20 moves, it can drive the transmission rack 24 to move horizontally, and then drive the pressure roller 37 to move downward, and move the pressure roller 37 to the bottom of the support plate 32;

[0083] S7. By starting the traction vehicle to drive the equipment box 1 to move laterally, the pressure roller 37 can be driven to move. At this time, the scraper 34 moving laterally can level the asphalt and gravel laid on the road surface that needs to be repaired, and when the pressure roller 37 passes, the spread asphalt and gravel can be compacted, so that when the road surface is repaired, targeted compaction can be performed without causing damage to the undamaged road surface.

At the same time, multiple electric heating rods 16 can be energized to heat the mixing box 10, so that the mixing box 10 is in a high temperature state. At this time, when the asphalt and sand are mixed and stirred, it can be prevented The asphalt solidifies, so that it can be fully mixed with the sand and gravel. After the asphalt and sand and gravel are mixed, the stepper motor 21 can be started to drive the active bevel gear 22 to rotate. At this time, under the meshing transmission action with the driven bevel gear 23, the transmission shaft 18 can be driven to rotate. When the transmission shaft 18 rotates, the two rotating shafts 9 can be driven to rotate through the transmission cooperation of the two synchronous wheels 19 and the synchronous belt 20. When the rotating shaft 9 rotates, it can drive the mixing box 10 to flip downward 180°, so that the mixed asphalt and sand and gravel can be poured onto the conveyor belt 8, and when the synchronous belt 20 moves, it can drive the transmission rack 2 4 moves horizontally, and then under the meshing transmission action with the transmission gear 26, it can drive the transmission gear 26 to rotate, and at this time it can drive the connecting shaft 27 to move in a longitudinal arc shape, that is, it can drive the transmission rod 28 to move. At this time, under the sliding cooperation of the transmission rod 28 and the connecting plate 29, it can drive the connecting plate 29 to move longitudinally. When the connecting plate 29 moves downward, it can drive the fixing frame to move downward through the two L-shaped mounting rods 35, so as to drive the pressure roller 37 to move downward, and move the pressure roller 37 to the bottom of the support plate 32. Then, the conveying motor 4 can be started to drive the active roller 5 to rotate. At this time, multiple support rollers 7 and driven rollers can be moved. With the support and cooperation of the roller 6, the conveyor belt 8 can be driven to move. After the asphalt and gravel are in contact with the guide plate 33 during movement, the asphalt and gravel can be discharged along the guide plate 33 and fall on the road surface that needs to be repaired. After that, the equipment box 1 can be driven to move laterally by starting the traction vehicle, which can drive the pressure roller 37 to move. At this time, the scraper 34 that moves laterally can level the asphalt and gravel laid on the road surface that needs to be repaired, and when the pressure roller 37 passes, the paved asphalt and gravel can be compacted, so that when the road surface is repaired, targeted compaction can be carried out without causing damage to the undamaged road surface.
