[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] The utility model provides a technical solution: Figure 1-Figure 4 As shown, in the present embodiment, a highway construction asphalt paving device comprises: a material distributing mechanism 1, the material distributing mechanism 1 comprises a material discharge box 11, a material feed port 12 is arranged on the top of the material discharge box 11, a top cover 13 is arranged on the top of the material feed port 12, a material distributing plate 14 is arranged inside the material discharge box 11, the material feed port 12 is docked at the top of the material discharge box 11, one side of the top cover 13 is movably connected with one side of the material feed port 12 by a hinge, two ends of the material distributing plate 14 are respectively fixedly connected to two sides of the inner wall of the material discharge box 11, a material discharge port 15 is arranged on the bottom side of the inside of the material discharge box 11, a motor 16 is arranged on one side of the material discharge port 15, a material distributing blade 17 is arranged inside the material discharge port 15, the material discharge box 11 is docked with the material discharge port 15 on the bottom side of the inside, the outer surface of the motor 16 is docked in a slot opened on one side of the material discharge box 11, and the output end of the motor 16 passes through one side of the material discharge port 15 and is connected with the material distributing blade 17 The ends are fixedly connected, pressure rollers 18 are provided at both ends of the bottom of the discharge box 11, and the other end of the dividing blade 17 is rotatably connected to the side of the inner wall of the discharge port 15 away from the motor 16. Pressure rollers 18 are docked at both ends of the bottom of the discharge box 11, and two mounting frames 19 are provided between the two pressure rollers 18. Heating rollers 110 are provided in the two mounting frames 19. The tops of the two mounting frames 19 are fixedly connected to the bottom of the discharge box 11, and the two mounting frames 19 are docked with heating rollers 110. A rectangular spray pipe 111 is provided on the inner wall of the feed port 12, and a plurality of nozzles 112 are provided on the inner circle of the rectangular test tube. The inner wall of the feed port 12 is fixedly connected to the outer surface of the rectangular spray pipe 111, and a plurality of nozzles 112 are docked on the inner circle of the rectangular test tube. A heating bin 113 is provided inside the discharge box 11, and a cleaning mechanism 2 is provided in the card slot opened on one side of the top of the discharge box 11.
[0023] In this embodiment, when the staff uses the device to pave asphalt on the highway, they first put the asphalt material into the discharge box 11, and the asphalt material will fall on both sides of the inside of the heating bin 113 through the dividing plate 14 to avoid the accumulation of materials in one place. The heating bin 113 will heat the asphalt material and drive the dividing blade 17 to rotate by starting the motor 16. When the dividing blade 17 rotates, the asphalt material accumulated at the discharge port 15 will be discharged evenly. When the asphalt material falls on the highway, the heating roller 110 and the pressing roller 18 will flatten the asphalt material to ensure that the asphalt material can fit tightly on the highway, thereby forming a flat and solid highway surface.
[0024] like Figure 1-Figure 4 As shown, the cleaning mechanism 2 includes a water tank 21, which is docked in a slot opened on one side of the top of the discharge box 11. A water pump 22 is docked in the water tank 21. The output end of the water pump 22 is docked with one end of a water pipe 23. The other end of the water pipe 23 passes through the water tank 21 and is docked with one side of the feed port 12 on the rectangular spray pipe 111.
[0025] In this embodiment, after the device is used, residual asphalt materials will adhere to the inner wall of the heating bin 113. The long-term accumulation of these materials on the inner wall of the heating bin 113 may cause damage to the equipment, thereby shortening the service life of the equipment. Therefore, the water pump 22 can be started to transport the water in the extraction tank 21 to the water pipe 23, and then transmitted to the rectangular spray pipe 111 through the water pipe 23. The heating bin 113 is cleaned through the nozzle 112, saving the work and energy of the staff in cleaning the residual asphalt materials.
[0026] The utility model provides an asphalt paving device for highway construction, and the specific working principle is as follows:
[0027] When the staff uses the device to perform asphalt paving operations on highways, they first need to pour the prepared asphalt material into the discharge box 11 of the equipment. At this time, the asphalt material will pass through the dividing plate 14 inside the equipment and be evenly distributed on both sides of the interior of the heating bin 113. Next, the heating bin 113 begins to heat the asphalt material. At the same time, the dividing blade 17 is driven to rotate by the starting motor 16. When the dividing blade 17 rotates, it will evenly stir and discharge the asphalt material accumulated at the discharge port 15 to ensure that the asphalt material can be evenly distributed on the highway. When the asphalt material is discharged from the equipment, When it falls onto the road, the heating roller 110 and the pressing roller 18 of the equipment start working, and they will flatten the asphalt material to ensure that the asphalt material can fit tightly on the road, thereby forming a flat and solid road surface. However, when the device is used up, residual asphalt material may adhere to the inner wall of the heating chamber 113. By starting the water pump 22 of the equipment, the water pump 22 will pump water from the water tank 21 into the water pipe 23, and then transmit it to the rectangular spray pipe 111 through the water pipe 23. Finally, the heating chamber 113 is cleaned by the nozzle 112 to clean the residual asphalt material.
[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
