Technical Field
[0001] This utility model relates to the field of asphalt mixing technology, and in particular to an asphalt mixture mixing device. Background Technology
[0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder. Some also contain polymers and wood cellulose. These materials of different qualities and quantities are mixed to form different structures and have different mechanical properties. According to the material composition and structure, it is divided into continuous gradation and discontinuous gradation mixtures. According to the mineral aggregate gradation composition and porosity, it is divided into dense gradation, semi-open gradation, and open gradation mixtures.

[0024] The carrying compartment 202, the rear cover 203, and the front cover 205 are connected in a multi-segment straight-through movable sleeve structure.
[0025] In this embodiment, the hydraulic telescopic arm 204 can be used to close the rear cover 203 onto the bearing chamber 202 after it is in operation. Then, the feed port 207 on the front cover 205 is used to output a sufficient amount of material into the bearing chamber 202, so that the driven gear ring 201 and the bearing chamber 202 can achieve a rolling effect after they are in operation.
[0026] The mobile heating angle adjustment assembly 1 includes a moving wheel 101, a platform 102, a pneumatic pressure relief pad 103, a fixed hinge frame 104, a heat insulation chamber 105, a movable hinge seat 106, a hydraulic telescopic frame 107, and a cylinder base 108. The platform 102, on which the pneumatic pressure relief pad 103 is installed, is provided above the moving wheel 101.

After the internal motor 309 outputs power to drive the output end to run, the eccentric wheel assembly 3010 can efficiently mix the products inside.
[0034] The working principle of this asphalt mixture mixing device is as follows: During operation, the moving wheels 101 move the platform 102 to the target location, where it is supported by the pneumatic pressure relief pad 103. Then, the first motor 1011 drives the output end, which in turn drives the meshing gear set 1012 and the drive gear 1013 on the top box 1010 for output operation. A heating rod 109 is used to achieve a heating effect. When mixing is required, the second motor 301 drives the conveyor belt... The output end operates, causing the mixing rack 307 to rotate in conjunction with the empty pipe 308. The output end is driven by the internal motor 309, which in turn drives the eccentric wheel assembly 3010 to efficiently mix the internal products. The output of the second motor 301 drives the splined insert rod 302, which in turn drives the bearing crossbeam 303 to rotate the rotating connecting beam 305 and the cleaning scraper ring 306. When discharge is required, the hydraulic telescopic arm 204 on the rear cover 203 is used to open the rear cover 203. After opening, the hydraulic telescopic frame 107 on the cylinder base 108 drives the output end, which, with the cooperation of the movable hinge seat 106 and the fixed hinge frame 104, adjusts the bearing chamber 202 to a suitable angle. This, along with the hydraulic telescopic rod 304, the rotating connecting beam 305, and the cleaning scraper ring 306, pushes against the inner wall to discharge the material.
