[0002] The construction of road projects plays a vital role in the economic development of cities. Asphalt is needed for road paving. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. During the construction of road projects, the asphalt mixture needs to be fully mixed before paving.
[0003] The Chinese patent publication number CN221480471U discloses a device for paving asphalt mixtures for road construction. According to its specification, the device scrapes and levels the falling asphalt using a vertical scraper.
[0004] However, since the falling asphalt will be in a piled-up state and since asphalt has viscosity, this direct scraping method will cause the asphalt to move directly with the scraper, reducing its extensibility to both sides, which can easily cause relatively large gaps in the road surface, thereby reducing the paving effect of the device.
[0005] Therefore, it is necessary to provide a new asphalt mixture mixing and paving device to solve the above technical problems. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides a mixing and paving device for asphalt mixture.

[0008] The diffusion assembly includes a fixing frame, which is fixedly mounted on the side wall of the mixing drum. A sliding-connected adapter frame is inserted into the interior of the fixing frame. A plurality of diffusion strips are fixedly mounted on the bottom of the adapter frame. The plurality of diffusion strips are staggered and distributed. A scraper for leveling the asphalt is fixedly mounted on the side of the bottom of the adapter frame away from the mixing drum.
[0009] Preferably, a slidingly connected insertion rod is inserted on both sides of the interior of the fixing frame, a fixedly connected mounting frame is installed at the bottom end of the insertion rod, and a rotatably connected rolling cylinder is installed between the mounting frames on both sides.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0025] See also Figures 1 to 5 The embodiment of the present invention provides a mixing and paving device for asphalt mixture, and the mixing and paving device for asphalt mixture includes: a mixing drum 1.
[0026] In the embodiments of the present invention, please refer to Figures 1 to 5 A mixing frame 2 for stirring asphalt is installed inside the mixing drum 1, and a diffusion component 4 for diffusing the falling asphalt is installed outside the mixing drum 1; the diffusion component 4 includes a fixed frame 41, which is fixedly installed on the side wall of the mixing drum 1, and a slidingly connected adapter frame 42 is inserted inside the fixed frame 41. A plurality of diffusion strips 421 are fixedly installed at the bottom of the adapter frame 42, and the plurality of diffusion strips 421 are staggered. A scraper 422 for leveling the asphalt is fixedly installed on the side of the bottom of the adapter frame 42 away from the mixing drum 1, a hydraulic cylinder 412 is fixedly installed at the bottom of the fixed frame 41, and the bottom end of the hydraulic cylinder 412 is fixedly connected to the adapter frame 42, and a slidingly connected insertion rod 52 is inserted on both sides of the inside of the fixed frame 41, and a fixedly connected mounting frame 5 is installed at the bottom end of the insertion rod 52, and a rotatably connected rolling drum 51 is set between the mounting frames 5 on both sides.
[0027] It should be noted that: since the diffusion strips 421 are staggered, during the asphalt paving process, the diffusion strips 421 can plow the falling asphalt to achieve multi-level diversion of the asphalt, making the asphalt paving more uniform, and then leveling it through the scraper 422, which can improve the flatness and compactness of the later paving. After the asphalt is laid and scraped, the rolling roller 51 can automatically assist in compaction, thereby helping to improve the compactness of the asphalt paving.
[0028] In the embodiments of the present invention, please refer to Figures 1 to 5A through hole 411 is provided on both sides of the interior of the fixing frame 41. The inner wall of the through hole 411 is abutted against and slidably connected to the outer wall of the insertion rod 52. A protruding rod 53 is fixedly installed on the top of the insertion rod 52. The outer wall of the protruding rod 53 is provided with a threaded limit sleeve 54, and the outer wall specification of the limit sleeve 54 is larger than the outer wall specification of the insertion rod 52.
[0029] It should be noted that: through the installation of the limit sleeve 54, the limit sleeve 54 can block the falling trajectory of the insertion rod 52 during use, and then when the external traction equipment transports the device, the limit sleeve 54 can prevent the insertion rod 52 from falling off from the inside of the fixed frame 41, thereby achieving stable support for the rolling drum 51.
[0030] In the embodiments of the present invention, please refer to Figures 1 to 5 A connecting frame 12 is fixedly installed on the side of the mixing drum 1 away from the diffusion component 4, a material discharge chute 11 is opened at the bottom of the mixing drum 1, a fixedly connected support frame 3 is mounted on the outer wall of the mixing drum 1, a rotatably connected sealing plate 31 is mounted inside the support frame 3, and a rotating motor 32 for driving the sealing plate 31 is fixedly mounted on the outer wall of the support frame 3.
[0031] It should be noted that the rotating motor 32 used to drive the sealing plate 31 is a self-locking motor, so that when the sealing plate 31 rotates to the bottom of the discharge trough 11, the discharge trough 11 can be blocked and sealed, and then during the asphalt mixing process, the asphalt can be prevented from overflowing and leaking from the discharge trough 11, thereby achieving smooth mixing of the asphalt.
[0032] The working principle of the asphalt mixture mixing and paving device provided by the utility model is as follows:
[0033] When using this device, the device can be installed on an external traction device through the connecting frame 12, and then the required asphalt mixed raw materials are added to the interior of the mixing drum 1. The mixing frame 2 is controlled to rotate, and the rotating mixing frame 2 can stir and mix the raw materials added to the mixing drum 1. At this time, the device can be moved to the desired paving area through the external traction device.
[0034] Then, the rotating motor 32 can be controlled to rotate, and the working rotating motor 32 can drive the blocking plate 31 to rotate, so that the blocking plate 31 can remove the obstruction of the discharge chute 11, and then the mixed asphalt can be smoothly discharged downward through the discharge chute 11;
[0035] At this time, the staff can control the hydraulic cylinder 412 to work to adjust the height of the spreading strip, and then when the external traction equipment drives the device to move, the vertically distributed diffusion strips 421 can smoothly plow and spread the fallen asphalt, so that the distribution of the fallen piled asphalt can be more even, and the scraper 422 that moves later can further scrape the evenly diffused asphalt, so that the diffused asphalt can be laid evenly, and at the same time, the rolling drum 51 that moves later can roll the flatly laid asphalt to make the asphalt laying more compact, thereby improving the laying effect of the device.
[0036] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
[0037] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
