[0001] The utility model relates to the technical field of recycling of discarded pavement materials, in particular to a pavement material recycling device. Background Art

[0002] With the acceleration of urbanization and the continuous development of road construction, a large number of pavement materials need to be replaced or repaired due to aging, damage and other reasons. The traditional treatment method is often to directly discard or landfill these waste pavement materials, which not only wastes precious resources, but also causes serious pollution to the environment. Therefore, how to achieve the recycling of pavement materials has become a problem that needs to be solved urgently.

[0003] At present, there are some pavement material recycling devices on the market, but most of them have some problems. First, during the crushing process, due to the wear and low efficiency of the crushing equipment, it is often impossible to achieve efficient crushing of the pavement material, affecting the quality of the recycled material. Secondly, during the filtration process, due to the unreasonable design of the filtration equipment or poor filtration effect, the recycled material still contains a lot of dust and impurities and cannot meet the use requirements. In addition, some devices have problems such as high energy consumption, high maintenance costs, and inconvenient operation, which limits their promotion in practical applications.

[0004] To this end, we propose a pavement material recycling device. Utility Model Content

[0026] Working principle:

[0027] First, the pavement material enters the crushing frame 1 through the injection port, and is then crushed by the internal crushing roller 2. The surface of the crushing roller 2 is provided with a wear-resistant coating, which helps to increase its service life and crushing efficiency, ensuring that the pavement material can be crushed evenly and effectively;

[0028] The crushed material then enters the filter frame 3 through one side of the crushing frame 1. In the filter frame 3, the material will be filtered by the filter bag 5 to achieve material classification and dust removal. The wire mesh installed inside the filter bag 5 can enhance the filtering effect and ensure that the dust is effectively intercepted;

[0029] At the same time, an exhaust fan 4 is installed at the top of the filter frame 3. When the exhaust fan 4 is working, it will generate airflow to help blow off the dust on the filter bag 5. In addition, a transmission mechanism is installed inside the filter frame 3. The mechanism cooperates with the clapper 6 to periodically clapper the filter bag 5 to further clean the residual dust on the filter bag 5.

[0030] The working principle of the transmission mechanism is as follows: when the material in the crushing frame 1 is crushed, part of the material will splash onto the impact plate 62, and the impeller 63 at the bottom end of the impact plate 62 will rotate accordingly. The rotation of the impeller 63 drives the active bevel gear 65 to rotate through the connecting shaft 64. The active bevel gear 65 meshes with the driven bevel gear 67, thereby driving the crankshaft 66 to rotate. The connecting rod 68 on the crankshaft 66 moves accordingly, pushing the piston 69 in the connecting sleeve 61 to move up and down. The top end of the piston 69 is fixedly connected to the clapper 6, so the up and down movement of the piston 69 will drive the clapper 6 to slap the filter bag 5;

[0031] The clapper 6 is made of elastic material, which can provide a buffering effect when clapping the filter bag 5 to prevent damage to the filter bag 5. At the same time, the side wall of the filter frame 3 is provided with an observation window, which is convenient for observing the internal filtering situation so as to clean or replace the filter bag 5 in time.
