Detailed Implementation

[0028] 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.

[0029] Reference Figures 1-3This utility model provides an embodiment of a waste asphalt mixture screening structure, including a support frame 1. A fixed pipe 2 is fixedly connected to the inner wall of the support frame 1, primarily supporting and connecting the entire connecting shaft 4. A rotating pipe 3 is rotatably connected to the outer wall of the fixed pipe 2, and a connecting shaft 4 is fixedly connected to the outer wall of the rotating pipe 3. The connecting shaft 4 primarily supports and connects the entire disc 5. The disc 5 is fixedly connected to the right end of the connecting shaft 4. A screening cylinder 6 is rotatably connected to the outer wall of the disc 5. A feed box 7 is fixedly connected to the top of the screening cylinder 6. The feed box 7 has a door, which can be opened to pour waste asphalt into the screening cylinder 6. After feeding, the door can be closed and locked using existing technology to prevent the entire screening cylinder 6 from being damaged. During rotation, waste asphalt is discharged from the feed box 7. An L-frame 8 is fixedly connected to the outer wall of the connecting shaft 4. The L-frame 8 mainly connects to the drive motor 9, ensuring that the L-frame 8 drives the drive motor 9 to generate an angle deflection. A drive mechanism is set above the L-frame 8. A filter screen 12 is detachably installed on the outer wall of the screening cylinder 6. The filter screen 12 on the screening cylinder 6 has a pore size that increases from fine to coarse from left to right, which can filter waste asphalt materials of different sizes. A ring block 13 is rotatably connected to the outer wall of the screening cylinder 6. A collection box 14 is fixedly connected to the bottom end of the ring block 13. A drawer 15 is inserted into the inner wall of the collection box 14, which allows the screened waste asphalt material to fall into the drawer 15 for collection. An adjustment component is set on the left side wall of the support frame 1.

[0030] The drive mechanism includes a drive motor 9, which is an FF series parallel shaft helical gear reducer motor. The drive motor 9 is set to a slow speed, which allows the entire screening cylinder 6 to perform slow screening. The drive motor 9 is mounted on the L frame 8. The output end of the drive motor 9 is fixedly connected to a drive gear 10, and the outer wall of the drive gear 10 is meshed with a tooth block 11.

[0031] Reference Figures 2-4The adjustment assembly includes a fixed frame 19, which is fixedly connected to the left end of the support frame 1. A connecting motor 20 is fixedly connected to the inner wall of the fixed frame 19. The connecting motor 20 is a ZW series helical gear worm gear reducer motor, which uses a combination of helical gears and worm gears for integrated transmission. Its worm gear portion has a self-locking function, which is existing technology and will not be elaborated further here. This ensures the stability of the entire screening cylinder 6's rotation and stability during use. The fixed frame 19 mainly supports and connects the entire connecting motor 20. A connecting gear 21 is fixedly connected to the output end of the connecting motor 20. A gear ring 22 meshes with the outer wall of the connecting gear 21. The rotating tube 3 is rotated by the connecting gear 21 and the toothed ring 22. A guide frame 18 is fixedly connected above the support frame 1. The guide frame 18 has an arc to allow the guide tube 17 to move along the track inside the guide frame 18. The guide tube 17 is slidably connected through the inner wall of the guide frame 18. The middle part of the guide frame 18 has a slot corresponding to the guide tube 17 to allow the guide tube 17 to slide. A connecting ring 16 is fixedly connected to the end of the guide tube 17. The connecting ring 16 is rotatably connected to the right side wall of the screening cylinder 6. The connecting ring 16 mainly supports and connects the screening cylinder 6. The toothed ring 22 is fixedly connected to the outer wall of the rotating tube 3.

[0032] Reference Figures 1-3 The toothed blocks 11 are fixedly connected to the outer wall of the screening cylinder 6. Multiple sets of toothed blocks 11 are provided and are evenly distributed. Multiple sets of collection boxes 14 and drawers 15 are provided and are evenly distributed below the screening cylinder 6.

[0033] Working principle: First, when screening is required, the waste asphalt mixture is poured into the screening cylinder 6 by opening the door on the feed box 7. After the material is added, the door is closed, the drive motor 9 is started, and its output end drives the drive gear 10 to rotate. The rotation of the drive gear 10 will cause the screening cylinder 6 to rotate around the disc 5. When the screening cylinder 6 rotates, the waste asphalt mixture will continuously tumble and move under the rotation of the screening cylinder 6. Waste asphalt materials of different coarseness will be screened according to the aperture of different positions of the filter screen 12. The finer material will fall first through the part corresponding to the finer aperture, while the coarser material will continue to tumble until it encounters the position of the appropriate aperture or stay in the screening cylinder 6 to continue rolling and wait for subsequent screening. The screened waste asphalt material will eventually fall into the drawer 15, realizing the collection of waste asphalt materials of different coarseness after screening.

[0034] When the screening angle needs to be adjusted, simply start the connecting motor 20. Its output end drives the connecting gear 21 to rotate, which in turn drives the gear ring 22 to rotate, thereby causing the rotating tube 3 to rotate. When the rotating tube 3 rotates, the angle of the entire screening cylinder 6 changes, and the guide tube 17 can move accordingly along the arc of the guide frame 18 to meet the angle adjustment requirements of the screening cylinder 6. Thus, the angle of the screening cylinder 6 can be flexibly adjusted according to the actual situation to better achieve the screening of waste asphalt mixture.

[0035] 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.
