Description

Technical Field

[0001] This utility model belongs to the field of asphalt technology, specifically relating to an asphalt pavement waste recycling and screening device. Background Technology

[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road-grade asphalt materials into mineral materials. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. The asphalt structural layer of asphalt pavement itself falls under the category of flexible pavements, but its base layer can also use rigid cement concrete or semi-rigid hydraulic materials in addition to flexible materials. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic binder, mainly used in industries such as coatings, plastics, and rubber, as well as in road paving. The asphalt used in road paving gradually hardens over time. However, in existing technologies, the waste materials from waste asphalt pavement cannot be fully crushed during recycling, which affects subsequent recycling work. Therefore, we have proposed an asphalt pavement waste recycling and screening device to address this issue. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides the following technical solution: an asphalt pavement waste recycling and screening device, including a rectangular crushing box 1, a crushing device is horizontally rotatably connected inside the rectangular crushing box 1, a feeding hopper 6 is installed at the lower part of the rectangular crushing box 1, a baffle plate 7 is installed on one side of the surface of the feeding hopper 6, a connecting rod 26 is installed in the middle of the surface of the baffle plate 7, a discharge bucket 9 is installed on the other side of the connecting rod 26, a sliding plate 22 is installed on the surface of the discharge bucket 9, a baffle 20 is installed on the lower side of the baffle plate 7, a support plate 16 is installed on the surface of the baffle plate 20, a second motor 8 is installed on the upper part of the support plate 16, a connecting cylinder 19 is movably installed on the lower side of the feeding hopper 6, a drum screen is movably connected to one end of the connecting cylinder 19, a fixing plate 27 is installed at the lower end of the drum screen, a second collection box 14 is placed below the bottom of the discharge bucket 9, and a first collection box 15 is placed below the bottom of the drum screen.

[0022] In this embodiment, multiple sets of crushing teeth are evenly distributed and spaced along the outer axial direction of the first crushing roller 2 and the second crushing roller 3, and the first crushing roller 2 and the second crushing roller 3 have an interlaced tooth design, which enables them to fully crush the materials in the waste asphalt pavement.

[0023] In this embodiment, by setting the conveyor plate 21, the crushed waste can be filtered more effectively.

[0024] In this embodiment, by setting the first universal wheel 25 and the second universal wheel 24, the staff can easily push the crushed waste material.

[0025] In this embodiment: the slide plate 22 can be used to clear the crushed waste that has accumulated on the discharge bucket 9.

[0026] The working principle and usage process of this utility model are as follows: After installation, asphalt pavement waste is poured into the rectangular crushing bin 1. The first motor 4 drives the first gear 17 to rotate the second gear 18, which in turn rotates the first crushing roller 2 and the second crushing roller 3. The crushed waste falls through the hopper 6 into the connecting cylinder 19, and then into the drum screen. The second motor 8 rotates the drum screen, causing large particles of waste in the hopper 6 to remain inside the drum screen and fall into the first collection box 15 from the inclined direction of the drum screen. Small particles of waste are... The drum screen ejects small particles of waste directly into the discharge hopper 9, while some particles fall onto the baffle plate 7 and eventually into the discharge hopper 9. When small particles accumulate in the discharge hopper 9, the pipes in the discharge hopper 9 can be cleared by sliding the slide plate 22. Finally, the small particles will fall into the second collection box 14. The collected large particles of waste are then poured back into the rectangular crushing box 1 for secondary crushing. All electrical equipment in this device is powered by an external power source, and all motors in this device are connected and controlled by a PLC control system.
