[0019] Embodiment:

[0020] Please refer to Figs. 1-4,

[0021] An asphalt paving device for highway construction, comprising a bottom plate 1, the top outer wall of the bottom plate 1 is fixedly installed with two L-shaped plates 2, the outer wall of the two L-shaped plates 2 is fixedly installed with two hydraulic rods one 3, the output end of the two hydraulic rods one 3 is fixedly installed with a U-shaped frame 4, the inside of the U-shaped frame 4 is rotatably connected with a rotating shaft 5, the outer wall of the rotating shaft 5 is fixedly sleeved with a rolling roller 6, the outer wall of the rolling roller 6 is movably sleeved with a shielding plate 7, the two shielding plates 7 are fixedly installed with a two-way electric push rod two, the outer wall of the two-way electric push rod two is fixedly sleeved with a connecting plate 8, the top outer wall of the connecting plate 8 is fixedly installed with two guide rods one 9, the outer wall of the connecting plate 8 is fixedly installed with a splicing plate 10, the inside of the splicing plate 10 is slidably connected with two guide rods two 11, the inside of the bottom plate 1 is fixedly installed with a storage bin 12, the outer wall of the storage bin 12 is fixedly installed with a motor one 13, the output end of the motor one 13 is fixedly installed with a stirring shaft 14, the outer wall of the bottom plate 1 is fixedly installed with a two-way electric push rod one 15, the inside of the storage bin 12 is slidably connected with two blocking plates 16, the outer wall of the bottom plate 1 is fixedly installed with two top plates 17, the two top plates 17 are rotatably connected with a drive wheel 18, the outer wall of the bottom plate 1 is fixedly installed with a motor two 19, the output end of the motor two 19 is movably sleeved with a drive belt 20;

[0022] Specifically, when the device needs to move, the motor two 19 is started, the motor two 19 drives the drive belt 20 to rotate, the drive belt 20 will drive the drive wheel 18 to rotate, because the drive wheel 18 contacts the ground, so the drive wheel 18 can drive the device to move, to realize the effect of stable movement;

[0023] When asphalt needs to be added, the motor 13 is turned on, which drives the mixing shaft 14 to rotate. As the mixing shaft 14 rotates, the scraper can move the asphalt, so that the asphalt can be evenly distributed and spread evenly on the ground to be paved. When it is necessary to adjust the distance between the two sealing plates 16, the bidirectional electric actuator 15 is controlled. The bidirectional electric actuator 15 will drive the sealing plates 16 to move, thereby achieving the effect of adjusting the distance between the sealing plates 16. It can be adjusted according to the paving width, which solves the problem that the existing asphalt paving device cannot be adjusted according to the asphalt paving width in actual use, and is not convenient to use.

[0024] When the device needs to compact the paved asphalt, the hydraulic rod 3 is controlled, which moves the U-shaped frame 4, causing the compaction roller 6 to move downwards and fit against the asphalt pavement. Then, driven by the drive unit, the compaction roller 6 compacts the asphalt pavement. The bidirectional electric actuator 2 controls the movement of the side baffles 7, adjusting the compaction range of the roller 6. Figure 2 As shown, the area below the contact surface between the roller 6 and the baffle plate 7 is hollow, which will not affect the rolling process of the roller 6. When the hydraulic rod 3 operates, it will control the U-shaped frame 4 to fit against the connecting plate 8. At this time, the bottom of the U-shaped frame 4 is higher than the bottom of the roller 6, so the U-shaped frame 4 will not contact the ground.

[0025] In the embodiment: the interior of the drive belt 20 is movably connected to the outer wall of the drive wheel 18, and the outer wall of the drive wheel 18 is provided with anti-slip grooves;

[0026] Specifically, the drive belt 20 is connected to the drive wheel 18, which can drive the drive wheel 18 to rotate, thus enabling the drive wheel 18 to move and the base plate 1 to move. The anti-slip groove is designed to increase friction and better drive the device to move.

[0027] In this embodiment: a plurality of scrapers are fixedly installed on the outer wall of the stirring shaft 14, and the plurality of scrapers are arranged in a circumferential array on the outer wall of the stirring shaft 14;

[0028] Specifically, multiple scrapers are fixedly installed on the outer wall of the mixing shaft 14, which can mix the asphalt inside the storage bin 12 and scrape the material to discharge the asphalt into the storage bin 12, thereby achieving the effect of uniformly discharging the asphalt.

[0029] In the embodiment: the output end of the bidirectional electric actuator 15 is fixedly connected to the outer wall of the two sealing plates 16, and the outer wall of the two guide rods 9 is slidably connected to the inside of the U-shaped frame 4.

[0030] Specifically, the bidirectional electric push rod 15 is fixedly connected to the sealing plate 16 to achieve the effect of pushing the sealing plate 16 to move. The width of the material can be adjusted according to the width of the road repair, achieving an adjustable effect. The guide rod 9 is slidably connected to the inside of the U-shaped frame 4 to achieve the effect of stabilizing the movement of the U-shaped frame 4, and can achieve the effect of adjusting the up and down position of the rolling roller 6.

[0031] In the embodiment: a movable plate is fixedly installed on the outer right side of the base plate 1, and the outer wall of the movable plate is fixedly connected to the outer walls of the two guide rods 11.

[0032] Specifically, the base plate 1 is equipped with a movable plate to support the guide rod 11, which can restrict the movement direction of the splicing plate 10;

[0033] In the embodiment: the bidirectional electric actuator 15, bidirectional electric actuator 2, motor 13 and motor 2 19 are existing structures, and the control circuit can be implemented by those skilled in the art through simple programming. They are common knowledge in the art and are only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0034] Working principle: When asphalt needs to be added, the motor 13 is turned on to drive the mixing shaft 14 to rotate. As the mixing shaft 14 rotates, the scraper moves the asphalt, allowing the asphalt to be evenly distributed and spread evenly on the ground to be paved. When it is necessary to adjust the distance between the two sealing plates 16, the bidirectional electric actuator 15 is controlled to move the sealing plates 16, thereby adjusting the distance between the sealing plates 16. This can be adjusted according to the paving width, solving the problem that existing asphalt paving devices cannot be adjusted according to the width of the asphalt paving, making them inconvenient to use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
