Description

Technical Field

[0001] This utility model belongs to the field of asphalt pavement technology, and more specifically, it relates to a high-density asphalt pavement paving device. Background Technology

[0002] Asphalt paving is a crucial step in road construction, directly determining the road's smoothness, durability, and driving comfort. The paving of hot-mix asphalt pavement consists of paving and compaction. The paver spreads the mixture onto the underlying layer, and the roller performs initial compaction, secondary compaction, and final compaction processes to ultimately obtain a dense and formed pavement.

[0003] Application number CN202421284484.2 discloses a high-density asphalt mixture paving and forming device, including a transport vehicle with a hopper fixedly installed on it and a paving mechanism. This invention, by setting up the paving mechanism, evenly spreads asphalt onto the ground, improving paving efficiency and ensuring uniform asphalt distribution. It allows for precise adjustment of the asphalt paving thickness, offering high flexibility to meet the specific requirements of different projects for asphalt layer thickness. Adjusting the height of the pressure roller located between two connecting frames and the asphalt ground allows for initial compaction of the freshly paved asphalt, ensuring uniform compaction of the asphalt mixture during paving, thereby improving the smoothness and density of the road surface and facilitating subsequent high-density compaction operations. It features high efficiency, flexibility, and integration, significantly improving the construction quality and efficiency of asphalt pavement.

[0004] Based on the above patent search and understanding of the application of existing high-density asphalt pavement pavers: existing asphalt pavement pavers have difficulty ensuring that the mixture is evenly distributed on the road surface during the paving process. This will result in differences in the density of different parts of the road surface, affecting the quality and service life of the road surface. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a high-density asphalt pavement paving device, including a mobile frame 1; a mixing tank 101 is fixedly installed in the middle of the interior of the mobile frame 1, a door is provided at the top of the mixing tank 101, and a discharge trough is provided at the lower front end of the mixing tank 101. A discharge plate 105 is fixedly installed at the front end of the discharge trough of the mixing tank 101. A telescopic plate 106 is fixedly installed at the lower middle front end of the mobile frame 1. When the telescopic plate 106 is extended, it fits against the interior of the discharge plate 105. A converging frame 2 is fixedly installed at the lower middle front end of the mobile frame 1. An extension 201 is provided at the lower front end of the converging frame 2. A dual-shaft motor 202 is fixedly installed at the middle bottom of the extension 201. A screw conveyor 203 is fixedly connected to the left and right rotating shafts of the dual-shaft motor 202.

[0029] The mobile frame 1 has a traction handle 102 at its rear end and a motor A103 fixedly installed at the middle of its rear end. The front end of the rotating shaft of the motor A103 is fixedly connected to the middle of the rear end of the mixing tooth 104. The mixing tooth 104 is located in the middle of the interior of the mixing tank 101.

[0030] Among them, a flattening frame 3 is fixedly installed at the middle position of the front end of the converging frame 2, and a motor B301 is fixedly installed at the middle position of the rear end of the flattening frame 3. The rotating shaft of the motor B301 is fixedly connected to the middle position of the rear end of the turntable 302. An extension rod is provided at the front edge of the turntable 302, and the turntable 302 is located at the front end of the flattening frame 3.

[0031] Among them, a half-gear swing member 303 is rotatably connected to the lower middle position of the front end of the flattening frame 3. The lower position of the half-gear swing member 303 is designed as a half-gear structure, and a strip groove is opened at the upper middle position of the half-gear swing member 303. The extension rod of the turntable 302 is located in the strip groove of the half-gear swing member 303.

[0032] Among them, a combing frame 304 is slidably connected to the lower front end of the flattening frame 3. A rack is provided at the top of the combing frame 304, and the rack of the combing frame 304 meshes with the lower half gear of the half gear swing member 303. The bottom of the combing frame 304 is designed in the shape of a mountain.

[0033] When using:

[0034] Add an appropriate amount of asphalt mixture into the mixing tank 101, close the door of the mixing tank 101, start the motor A103, the rotating shaft of the motor A103 drives the mixing tooth 104 to rotate inside the mixing tank 101, and stir the mixture to make the mixture uniform.

[0035] The operator moves the mobile frame 1 on the road surface by pulling the handle 102. According to the paving requirements, the operator controls the extension state of the telescopic plate 106 so that the telescopic plate 106 fits into the internal position of the discharge plate 105. The operator adjusts the opening size of the discharge chute of the mobile frame 1 to control the discharge amount of the mixture.

[0036] After the mixture is discharged from the discharge chute of the moving frame 1 to the discharge plate 105, it will fall into the interior of the converging frame 2. The converging frame 2 will then transfer the mixture to the ground position. Next, the dual-shaft motor 202 will be started. The left and right shafts of the dual-shaft motor 202 will drive the screw conveyor 203 to rotate, and the mixture will be evenly transported to the rear end of the flattening frame 3.

[0037] When motor B301 is started, its shaft drives turntable 302 to rotate. The extension rod at the front edge of turntable 302 moves within the slot of the half-gear oscillating component 303, thereby causing the half-gear oscillating component 303 to oscillate.

[0038] The half-gear structure below the half-gear swing member 303 meshes with the rack at the top of the combing frame 304, causing the combing frame 304 to slide laterally back and forth below the front end of the flattening frame 3.

[0039] The mountain-shaped design at the bottom of the 304 combing frame combs the paved mixture, improving the density and smoothness of the subsequent road surface.
