Description

Technical Field

[0001] The utility model relates to the technical field of pavers, in particular to an asphalt pavement thermal regeneration paver. Background Art

[0002] With the progress and development of society, roads are no longer made of concrete, but are all paved with asphalt. After long-term use, asphalt pavements will be crushed into potholes, ruts and cracks by passing vehicles. In order to ensure the flatness of the road surface and reduce the occurrence of traffic accidents, the asphalt pavement will be repaved or repaired. When repairing the asphalt pavement, in order to reduce costs, the original asphalt pavement will be reused, and then the asphalt pavement hot regeneration paver will appear.

[0003] A search revealed that Chinese patent publication number CN206279426U discloses a hot-regeneration asphalt pavement paving machine, comprising a vehicle head, an engine, a frame plate, and a crawler track mechanism. A storage tank is located on the top of the frame plate on the other side of the vehicle head. A feed hopper is located at one end of the top of the storage tank, and a mounting bracket is located at the other end of the top of the storage tank. A first motor is mounted within the mounting bracket, and the rotating shaft of the first motor passes through the top wall of the storage tank and extends into the interior of the storage tank. This utility model facilitates the discharge of asphalt from the storage tank and reduces asphalt coagulation in the storage tank by providing a first motor to drive a stirring rod. Furthermore, a blower is provided to blow air onto the regenerated asphalt pavement, thereby increasing the heat dissipation efficiency of the asphalt pavement and reducing the time it takes for the asphalt road to be opened to traffic. Furthermore, flattening rollers are provided on both sides of the blower to increase the smoothness of the regenerated asphalt pavement.

[0004] The above-mentioned device facilitates the discharge of asphalt from the storage tank by setting a first motor to drive the stirring rod, and at the same time, reduces the advantage of asphalt coagulation in the storage tank. However, during use, the asphalt will adhere to the inner wall of the storage tank. The above-mentioned device cannot scrape off the asphalt adhered to the inner wall of the storage tank, which will lead to insufficient use of the asphalt and increase the workload when cleaning the storage tank later. Therefore, an asphalt pavement hot regeneration paver is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

The interior of the paver 1 of the mixing barrel 5 is provided with a conveying assembly, a cleaning assembly includes a transverse plate 11, which is fixedly connected to the outer periphery of the connecting rod 10, and the front and rear ends of the bottom of the transverse plate 11 are fixedly connected to scrapers 12, a cleaning assembly includes a transverse plate 11, which is fixedly connected to the outer periphery of the connecting rod 10, and the front and rear ends of the bottom of the transverse plate 11 are fixedly connected to scrapers 12, a stirring assembly includes a transverse plate 2 14, which is fixedly connected to the outer periphery of the connecting rod 2 13, and the front and rear ends of the top of the transverse plate 2 14 are fixedly connected to stirring rods 15, and a pressure roller 4 is fixedly connected to the rear side of the paver 1.

[0024] Specifically, the paver 1 is the device body, which is used to pave the road surface, the mounting frame 2 is used to install the crawler 3, and the crawler 3 is the walking mechanism of the paver 1, which is convenient for movement, the mixing barrel 5 is used to contain asphalt and stir the asphalt, the box 6 is used to accommodate internal parts, the motor 1 7 is used to generate power to drive the bevel gear 1 8 to rotate, and the two bevel gears 2 9 are engaged with the bevel gear 1 8. When the bevel gear 1 8 rotates, the two bevel gears 2 9 rotate accordingly, but the rotation directions of the two bevel gears 2 9 are different. Because the rotation directions of the two bevel gears 2 9 are different, the directions of the connecting rod 10 and the connecting rod 2 13 are different. At this time, when the connecting rod 2 13 drives the cross plate 2 14 to rotate and the stirring rod 15 stirs the asphalt in the mixing barrel 5, the connecting rod 10 drives the cross plate 11 to rotate in the opposite direction, and the scraper 12 can scrape and clean the inner wall of the mixing barrel 5. The pressure roller 4 is used to roll and squeeze the discharged asphalt so that it can be spread on the road surface.

[0025] Reference Figure 1 - Figure 2The conveying assembly includes a second motor 18, which is fixedly connected to the inside of the paving vehicle 1. The output end of the second motor 18 is fixedly connected to a rotating rod 19, the periphery of the rotating rod 19 is fixedly connected to an auger plate 20, the periphery of the auger plate 20 is rotatably connected to a receiving tube 21, the bottom of the mixing barrel 5 is fixedly connected to a feed pipe 16, the bottom of the feed pipe 16 is fixedly connected to the top of the receiving tube 21, the rear bottom of the receiving tube 21 is fixedly connected to a discharge pipe 22, and the outer side of the feed pipe 16 is fixedly connected to a control valve 17.

[0026] Specifically, motor 2 18 is used to generate power to rotate the rotating rod 19, and the rotating rod 19 is used to connect the auger plate 20. The rotating rod 19 is driven to rotate by motor 2 18, so that the rotating rod 19 drives the auger plate 20 to rotate accordingly. The accommodating tube 21 is used to accommodate the rotating rod 19 and the auger plate 20. The feed pipe 16 is used to connect the mixing barrel 5 and the accommodating tube 21, so that the asphalt flows from the mixing barrel 5 into the accommodating tube 21. The control valve 17 is used to control the circulation of the feed pipe 16. The discharge pipe 22 is used to discharge the asphalt from the accommodating tube 21.

[0027] Working principle: When in use, drive the paver 1 to the road surface to be paved, and then pour asphalt into the mixing barrel 5. After the asphalt enters the mixing barrel 5, start the motor 17, and the motor 17 drives the bevel gear 18 to rotate. When the bevel gear 18 rotates, the two bevel gears 29 rotate accordingly, but the rotation directions of the two bevel gears 29 are opposite. When the two bevel gears 29 rotate, the connecting rod 213 drives the cross plate 214 to rotate, so that the two stirring rods 15 rotate accordingly to stir the asphalt in the mixing barrel 5, and the connecting rod 10 drives the cross plate 11 to rotate, and the two scrapers 12 scrape and clean the asphalt attached to the inner wall of the mixing barrel 5, so as not to waste asphalt and also help to clean the mixing barrel 5 after work.

[0028] Secondly, after the asphalt in the mixing barrel 5 is stirred, the control valve 17 is opened to allow the asphalt to flow from the inside of the mixing barrel 5 through the feed pipe 16 into the receiving pipe 21, and then the motor 2 18 is started. The motor 2 18 drives the rotating rod 19 to rotate, and the rotating rod 19 drives the auger plate 20 to rotate, so that the asphalt runs in the receiving pipe 21 and is finally discharged from the discharge pipe 22. The rotation speed of the auger plate 20 can be controlled by the rotation speed of the motor 2 18, and then the discharge speed of the asphalt can be controlled, thereby controlling the amount of asphalt used according to the different widths of the road surface.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
