The two toothed rollers 5 are arranged in parallel, and the two toothed rollers 5 are both located inside the feeding port 301. A discharge port 302 is penetrated on the side of the feeding port 301 away from the mixer body 1, and a screen 15 is hinged on the inner wall of the discharge port 302. One end of the rotating component away from the transmission component is connected to a plurality of vibration components, and the other ends of the plurality of vibration components penetrate the side wall of the feed hopper 3 and abut against the bottom surface of the screen 15 on the side away from the discharge port 302.

[0024] The mixer for asphalt concrete regeneration in the utility model is similar in structure to the existing mixer for asphalt concrete regeneration, such as the asphalt concrete mixer disclosed in the patent with announcement number CN217948664U. Figures 1 to 5 As shown, when the mixer for asphalt concrete regeneration in the utility model is used, the recycled asphalt concrete is first put into the feed hopper 3 through an external conveyor belt or other equipment, and then the power mechanism is started. After the power mechanism is started, the connected toothed roller 5 can be driven to rotate, and after the toothed roller 5 rotates, the transmission component can be driven to rotate. After the transmission component rotates, the other toothed roller 5 can be driven to rotate in the opposite direction, and then the asphalt concrete falling on the two toothed rollers 5 can be squeezed and crushed, so that large pieces of asphalt concrete are squeezed into small pieces, and then these small pieces of asphalt concrete will fall below The surface of the screen 15 is driven by the transmission component, and while driving the toothed roller 5 to rotate, it will also drive the rotating component to rotate, and the rotation of the rotating component will drive several vibration components to rotate together, and after the several vibration components rotate, the screen 15 can be driven to vibrate and bump, so that some smaller asphalt concrete will fall from the mesh holes of the screen 15 into the feed pipe 2 below, and then slide into the inside of the mixer body 1, while larger asphalt concrete will fall from the discharge port 302 on one side of the screen 15 to the outside of the mixer body 1, thereby avoiding the recycled asphalt concrete blocks of different sizes, which affects the quality of the asphalt concrete.

[0025] It should be noted here that the asphalt concrete dropped from the discharge port 302 can be collected and then transported to the top of the feed hopper 3 by external equipment for crushing, or directly collected for other treatments, without specific limitation.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the power mechanism includes a motor 4, the outer wall of the motor 4 is fixedly connected to one side of the outer wall of the feed hopper 3, the output shaft of the motor 4 passes through the side wall of the feed hopper 3, and is fixedly connected to one end of one of the gear rollers 5.

[0027] More specifically, when it is necessary to control the rotation of the gear roller 5, the motor 4 only needs to be turned on. After the motor 4 is started, the gear roller 5 can be driven to rotate, and after the gear roller 5 rotates, the transmission component can be driven to rotate.

[0028] like Figure 4 and Figure 5 As shown, the transmission assembly includes a first gear 8 and a third gear 11, which are respectively fixedly connected to one end of the two gear rollers 5 away from the motor 4, and the side of the third gear 11 away from the gear roller 5 is connected to the rotating assembly.

[0029] More specifically, when the gear roller 5 connected to the motor 4 rotates, it can drive the No. 1 gear 8 to rotate. When the No. 1 gear 8 rotates, it can mesh and drive the No. 3 gear 11 to rotate. When the No. 3 gear 11 rotates, it can drive another gear roller 5 and the rotating component to rotate together.

[0030] like Figure 4 and Figure 5 As shown, the rotating assembly includes a fourth gear 12 and a chain 9. One side of the fourth gear 12 is fixedly connected to the side of the third gear 11 away from the gear roller 5. The chain 9 is sleeved on the outside of the fourth gear 12 and several vibration assemblies, and the chain 9 is meshed with the fourth gear 12.

[0031] More specifically, as the third gear 11 rotates, the fourth gear 12 connected thereto rotates together, and when the fourth gear 12 rotates, the chain 9 meshing on the surface can be driven to rotate, thereby driving several vibration components to rotate together.

[0032] like Figure 4 and Figure 5 As shown, the vibration assembly includes a number two gear 10, a rotating rod 13 and an eccentric block 14. The outer wall of the rotating rod 13 is rotatably connected to the inner wall of the feed hopper 3. The end of the rotating rod 13 located inside the feed hopper 3 is fixedly connected to one end of the eccentric block 14. The end of the rotating rod 13 located outside the feed hopper 3 is fixedly connected to one side of the number two gear 10. The number two gear 10 is meshed with the chain 9, and the outer wall of the eccentric block 14 is against the bottom surface of the screen 15.

[0033] More specifically, when the chain 9 rotates driven by the No. 4 gear 12, it can engage and drive a number of No. 2 gears 10 to rotate. After the No. 2 gear 10 rotates, it can drive the rotating rod 13 and the eccentric block 14 to rotate. After the eccentric block 14 rotates, the bottom surface of the screen 15 can be shaken up and down, thereby achieving the effect and purpose of screening.

[0034] like Figure 1-Figure 3 As shown, a discharge pipe 7 is fixedly connected to one side of the feed hopper 3 near the discharge port 302. By providing the discharge pipe 7, the larger asphalt concrete discharged from the discharge port 302 can be guided so that it falls directly to the bottom without being scattered everywhere.

[0035] like Figure 1-Figure 3 As shown, a protective cover 6 is fixedly connected to the outer wall of one side of the feed hopper 3, and the transmission assembly, the rotating assembly and the vibration assembly are all located inside the protective cover 6. By providing the protective cover 6, the transmission assembly, the rotating assembly and the vibration assembly can be shielded and protected, which can not only prevent the transmission assembly, the rotating assembly and the vibration assembly from being stuck due to asphalt concrete falling during operation, but also make them look more beautiful in appearance.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
