[0003] Feeding devices are mechanical systems used in industrial production to automatically, continuously, and controllably transport raw materials or semi-finished products to processing equipment or production lines. Their core function is to achieve precise material supply and process connection, particularly in the field of waste asphalt material recycling.

[0004] However, when waste asphalt is transported by a conveyor belt, the end of the conveyor belt is uniformly transported to the inside of the holding box. However, during the transportation of waste asphalt, asphalt may stick to the conveyor belt and be difficult to clean, causing adhesion and blockage of the conveyor belt. To solve this problem, a waste asphalt material feeding device is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 One embodiment of this utility model is a waste asphalt material feeding device, which includes a support frame 4, a conveyor belt 3 at the top of the support frame 4, the support frame 4 supports the conveyor belt 3, and the waste asphalt is transported by the conveyor belt 3. The conveyor belt 3 is the prior art. A vibrating screen 1 is provided on the right side of the support frame 4, and the support frame 4 fixes the vibrating screen 1.

[0034] Reference Figures 2-4The vibrating screen 1 includes a connecting box 11, which is fixed on both sides of the support frame 4. The end of the connecting box 11 near the conveyor belt 3 is fixedly connected to the side wall of the support frame 4. The connecting box 11 serves to support the vibrating screen 1 to run on its surface. A connecting block 12 is fixedly connected to the upper end of the connecting box 11. A motor 13 is fixedly connected to the outer side wall of the connecting block 12. The output shaft of the motor 13 can drive the rotating shaft 14 to rotate around the central axis. The output shaft of the motor 13 is fixedly connected to the rotating shaft 14. The circumferential rotation of the rotating shaft 14 drives the rotating block 15 to rotate circumferentially. The lower end of the rotating block 15 is heavier than the upper end, so that the rotating block 15 always maintains the center downward position when rotating.

[0035] Furthermore, the outer wall of the rotating shaft 14 is rotatably connected to the inner wall of the connecting block 12. The end of the rotating shaft 14 away from the motor 13 is rotatably connected to the rotating block 15. The bottom end of the rotating block 15 is hinged to the hinge rod 16. The hinge rod 16 moves up and down, driving the vibrating plate 18 to vibrate up and down. The bottom end of the hinge rod 16 is hinged to the vibrating plate 18. The vibrating plate 18 can filter the waste asphalt by vibrating up and down. Larger asphalt particles that are not filtered can be manually removed from the inside of the connecting box 11. This allows the waste asphalt to be vibrated and filtered when it is transported into the inside of the connecting box 11, preventing some large particles of asphalt that cannot be processed from being filtered out. The side wall of the vibrating plate 18 is slidably connected to the inner wall of the connecting box 11, and the outer diameter of the vibrating plate 18 is completely matched with the inner diameter of the connecting box 11. The connecting box 11 provides support for the vibrating plate 18.

[0036] Reference Figure 1 and Figure 5 A scraper assembly 2 is provided on the inner side wall of the left side of the connecting box 11. The scraper assembly 2 can scrape off residual asphalt adhering to the conveyor belt 3 to clean it, keep the conveyor belt 3 unobstructed and reduce the risk of blockage caused by asphalt adhesion. The scraper assembly 2 includes a block 21. The bottom end of the block 21 engages with a groove on the surface of the scraper 22 to fix the scraper 22. A sliding groove is provided on the inner side wall of the top of the connecting box 11. The scraper 22 can be fixed to the inner wall of the connecting box 11 through the sliding groove, so that the scraper 22 can only be pulled and moved within the sliding groove. The outer wall of the block 21 slides... The connecting box 11 is attached to the inner wall of the sliding groove. The inner wall of the connecting box 11 has a cavity. The insert 21 is elastically connected to the cavity of the connecting box 11 by the spring 23. By pulling the insert 21, the spring 23 is pushed upward, causing it to disengage from the slot on the surface of the scraper 22. The side wall of the connecting box 11 has an installation groove. The scraper 22 is inserted into the inner wall of the installation groove. The scraper 22 is engaged by contacting the outer wall of the sliding groove on both sides of the connecting box 11. The outer side wall of the scraper 22 has a slot. The bottom end of the outer wall of the insert 21 is engaged with the inner wall of the slot of the scraper 22.

[0037] Furthermore, by fixing the scraper 22 with the insert block 21, the upper inclined surface of the scraper 22 contacts the conveyor belt 3, and the residual asphalt on the surface of the conveyor belt 3 is scraped off by the inclined surface of the scraper 22. One end of the spring 23 is fixedly connected to the inner wall of the cavity of the connecting box 11, and the other end of the spring 23 is fixedly connected to the surface of the insert block 21. The function of the spring 23 is to automatically reset the position of the insert block 21 after it moves, so that the insert block 21 engages with the slot on the surface of the scraper 22.

[0038] Working principle: When using this equipment, waste asphalt is conveyed to the connecting box 11 via conveyor belt 3. The output shaft of motor 13 drives rotating shaft 14 to rotate around the center. Rotating shaft 14 drives rotating block 15 to rotate. The rotation of rotating block 15 drives hinge rod 16 to move up and down. At the same time, due to the weight of rotating block 15 itself, it is always in a downward position. The up and down movement of hinge rod 16 drives vibrating plate 18 to vibrate up and down, achieving the effect of vibration filtration. The waste asphalt input into connecting box 11 is compacted by vibration, so that the asphalt is evenly distributed and prevents asphalt from accumulating and clumping. At the same time, it can filter some large particles of waste asphalt, which is convenient for centralized processing and secondary processing. It can save space inside connecting box 11 during the screening process. The waste asphalt that has been vibrated and filtered is discharged from the output port through the inclined surface at the bottom of connecting box 11.

[0039] Meanwhile, a scraper assembly 2 is installed near the conveyor belt 3 in the connecting box 11 to clean the residual asphalt adhering to the conveyor belt 3. If you want to disassemble and clean the scraper 22, simply pull the insert block 21. The upward force will squeeze the spring 23, causing the locking block at the bottom of the insert block 21 to disengage from the fixing groove on the surface of the scraper 22. Pull the scraper 22 to disengage it from the slot inside the connecting box 11 for disassembly. When you want to install the scraper 22 after cleaning, simply insert the scraper 22 into the slot on the surface of the connecting box 11. When the surface of the scraper 22 contacts the inclined surface at the bottom of the insert block 21, it will push the insert block 21 to slide upward until the scraper 22 is fully installed inside the connecting box 11. The spring 23 will automatically reset, causing the insert block 21 to reset and engage with the slot on the surface of the scraper 22 to complete the installation.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
