Description

Technical Field

[0001] The utility model relates to the field of pavers and discloses an asphalt paving machine. Background Art

[0002] The asphalt paver used in paving asphalt pavement is also called asphalt concrete paver or asphalt concrete paving machine. It is a special construction machinery for asphalt pavement. Its function is to evenly spread the mixed asphalt concrete material on the pavement subbase or base layer, and perform a certain degree of pre-compaction and shaping on it to form an asphalt concrete base layer or asphalt concrete surface layer. The paver can accurately ensure the paving layer thickness, width, pavement arch, flatness, and density. It is therefore widely used in asphalt concrete paving operations in projects such as highways, urban roads, large freight yards, parking lots, docks and airports. It can also be used for paving operations of stable materials and dry-hard cement concrete materials.

[0003] The patent number CN217174287U in the prior art introduces an asphalt pavement paving machine, which relates to the technical field of pavement paving machines, and improves the poor effect of uniformly paving asphalt in some existing asphalt pavement paving machines during use. The patent includes a base and a storage box arranged on the base, and the top of the base is located on one side of the storage box and fixedly installed with an equipment box, the inside of the equipment box is rotatably connected with a threaded rod, the outer surface of the threaded rod is connected with a driving mechanism, the outer surface of the threaded rod is located on one side of the driving mechanism and is threadedly connected with a moving plate, the inside of the moving plate is slidably connected with a sliding rod, both ends of the sliding rod are fixedly connected to the equipment box, and two connecting rods are symmetrically installed on one side of the moving plate, and the connecting rod runs through the base and the inside of the equipment box. When the application needs to pave asphalt, the scraper can be controlled to drop to a suitable height by the driving mechanism, and then the scraper can scrape and pave the asphalt on the road surface.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) When the prior art patent is in use, a lot of asphalt will remain on the inner wall of the storage box, causing waste and being difficult to clean.

[0006] (2) When the prior art patent is in use, asphalt can only be discharged from one discharge pipe and cannot be evenly laid on the ground. Utility Model Content

[0007] The technical problem to be solved by the utility model is to overcome the above technical defects and provide an asphalt paver which can not only clean up the remaining asphalt but also spread the asphalt more evenly.

A flattening device 6 is provided on the rear side of the storage tank 3 to flatten the asphalt on the road surface.

[0026] Specifically, a conveying auger 501 is rotatably connected inside the discharge barrel 5, and one end of the conveying auger 501 is connected to a third motor 502, which can control the rotation of the conveying auger 501. There are five discharge pipes 503 distributed at equal intervals at the bottom of the discharge barrel 5, which can discharge materials over a large range.

[0027] Through the above technical solution, the third motor 502 drives the conveying auger 501 to rotate, and the asphalt is transported from one end of the discharge barrel 5 to the other end. The asphalt is discharged from the five discharge pipes 503 at the bottom of the discharge barrel 5, thereby achieving uniform paving of the asphalt.

[0028] Specifically, the flattening device 6 includes a slide column 601, which is slidably connected to the vehicle body 1. The slide column 601 is internally threaded with a stud 602. A bracket 103 is provided at the upper end of the vehicle body 1. The upper part of the stud 602 is rotatably connected to the bracket 103. The bracket 103 can support the stud 602. A knob 603 is provided at the upper end of the stud 602 to facilitate the rotation of the stud 602. The slide column 601 will move in the vertical direction as the stud 602 rotates. A push plate 604 is provided at the bottom end of the slide column 601. A spreading plate 605 is provided below the push plate 604.

There are three evenly distributed telescopic rods 606 between the push plate 604 and the spreading plate 605. Buffer springs 607 are sleeved on the surface of the telescopic rods 606. The buffer springs 607 can provide downward pressure for the spreading plate 605 to spread the asphalt.

[0029] Through the above technical solution, rotating the knob 603 can rotate the stud 602, thereby moving the slide column 601 in the vertical direction to adjust the height of the spreading plate 605.

[0030] Specifically, the wall scraper device 4 includes a second motor 401, a screw 402 is provided at the bottom end of the second motor 401, the screw 402 is rotatably connected to the storage tank 3, the second motor 401 can drive the screw 402 to rotate, a sliding shaft 403 is provided on one side of the screw 402, the upper end of the sliding shaft 403 is fixedly connected to the storage tank 3, a wall scraper ring 404 is sleeved on the surface of the sliding shaft 403, the wall scraper ring 404 is in contact with the inner wall of the storage tank 3, one end of the wall scraper ring 404 is threadedly connected to the screw 402, and will move with the rotation of the screw 402.

[0031] Through the above technical solution, the second motor 401 can drive the screw 402 to rotate, thereby causing the scraper ring 404 to move up and down along the sliding shaft 403, so as to scrape off the asphalt on the inner wall of the storage tank 3.

[0032] When in use, first rotate the knob 603 to rotate the stud 602, and then move the sliding column 601 in the vertical direction to adjust the height of the spreading plate 605, then open the electromagnetic valve 303 to push the vehicle body 1 forward, and the asphalt enters the discharge barrel 5 through the discharge pipe 302. The third motor 502 drives the conveying auger 501 to rotate, and transports the asphalt from one end of the discharge barrel 5 to the other end. The asphalt is discharged from the five discharge pipes 503 at the bottom of the discharge barrel 5, so that the asphalt falls evenly on the ground, and then the asphalt is squeezed and flattened by the spreading plate 605. After the asphalt is laid, the second motor 401 can drive the screw 402 to rotate, and then the scraper ring 404 moves up and down along the sliding shaft 403, so as to scrape off the asphalt on the inner wall of the storage tank 3 to prevent the asphalt from solidifying inside the storage tank 3.
