[0032] like Figures 1 to 13As shown, embodiment 1: a concrete waste recycling system, comprising: a processing box assembly 1 and a first processing assembly 2; the processing box assembly 1 includes an inlet box 11, which receives large pieces of concrete waste; the inlet box 11 is fixedly connected to a crushing box 16, a first-level coarse crushing chamber; the crushing box 16 is connected to a grinding box 17, a second-level fine crushing chamber; the inlet box 11 is connected to a protective box 13, the protective box 13 is connected to a symmetrical L-plate 14, and the symmetrical L-plates 14 are respectively connected to a bottom plate 15; the grinding box 17 is connected to a convergent cover 18 with an inverted conical lining, and the grinding box 17 and the convergent cover are connected. The cover 18 forms two outlets 19; the first processing component 2 includes a main motor 21, the inlet box 11 is connected to the main motor 21, the inlet box 11 bearing is connected to the central axis of the symmetrical crushing roller 22, the output shaft of the main motor 21 is connected to the central axis of one of the crushing rollers 22, and the symmetrical crushing rollers 22 are respectively connected to a group of crushing blades 23 to perform primary shearing and crushing on the concrete blocks; the upper bearing of the grinding box 17 is connected to the central axis of the symmetrical sorting rollers 29, and the symmetrical sorting rollers 29 are respectively connected to a group of electromagnetic plates 210. During the rotation, the electromagnetic plates 210 are energized to generate a magnetic field to attract scrap steel bars and iron blocks; after power is cut off, the magnetic metal automatically falls off to achieve online iron removal; the bottom bearing of the grinding box 17 is connected to the central axis of the symmetrical grinding rollers 211, and the material after iron removal is subjected to secondary roller grinding, which can be directly used as recycled aggregate. The first processing assembly 2 is used to process concrete waste. Crushing rollers 22 and crushing blades 23 crush large chunks of concrete into small pieces. Some concrete adhering to ferrous materials such as rebar and steel plates is attracted by electromagnetic plates 210. When electromagnetic plates 210 are de-energized, these pieces fall through outlet 19, separating the ferrous materials. The small pieces of concrete are then ground into granules by grinding rollers 211, enabling concrete waste recycling. This constitutes a three-stage processing channel consisting of "primary crushing + magnetic separation and sorting + secondary grinding."

[0033] The inlet box 11 is connected to symmetrical transmission gears 25, which mesh with each other. The central axes of the symmetrical crushing rollers 22 are connected to power gears 24, which mesh with corresponding transmission gears 25. The central axes of the symmetrical crushing rollers 22 and the symmetrical sorting rollers 29 are connected to upper synchronous pulleys 26, with the ends of two upper synchronous belts 27 looping around their corresponding upper synchronous pulleys 26. The central axes of the symmetrical sorting rollers 29 and the symmetrical grinding rollers 211 are connected to lower synchronous pulleys 28, with the ends of two lower synchronous belts 212 looping around their corresponding lower synchronous pulleys 28. The inlet box 11 is connected to the protective cover 12, corresponding to the transmission gears 25, power gears 24, and upper synchronous belts 27. The inlet box 11 is provided with corresponding vertical slots for the upper synchronous belts 27. The gear meshing and synchronous belt drive enable the movement of the crushing rollers 22, sorting rollers 29, and grinding rollers 211, facilitating the recycling of concrete waste. Use "gear + synchronous belt" to achieve synchronous drive from a single motor to four axes, simplifying the transmission chain.

[0034] The system also includes an alignment assembly 4, comprising two mounting plates 41 and two first sensors 43. The central axes of the symmetrical sorting rollers 29 are connected to corresponding mounting plates 41. The protective box 13 is connected to the two first sensors 43. Each mounting plate 41 is equipped with a set of evenly distributed second sensors 42, with the first sensors 43 aligned with the second sensors 42. When the second sensors 42 and the first sensors 43 are in the same position, the corresponding electromagnetic plate 210 is de-energized, allowing ferrous material to fall from the outlet 19. When the second sensors 42 rotate with the mounting plates 41 and align with the first sensors 43, the system records the phase angle and precisely controls the timing of de-energizing the electromagnetic plate 210. After a period of time, the electromagnetic plate 210 is re-energized. Ferrous impurities are attracted at the high point and released when the electromagnetic plate 210 moves to the low point.

[0035] The workflow of this embodiment is: Concrete waste is poured into the inlet box 11 manually or using equipment, and the main motor 21 is controlled to rotate. The main motor 21 drives a crushing roller 22 and a power gear 24 to rotate. A power gear 24 drives a transmission gear 25, another power gear 24 and another crushing roller 22 to rotate. The crushing roller 22 drives the crushing blade 23 and the upper upper synchronous wheel 26 to rotate. The upper upper synchronous wheel 26 drives the upper synchronous belt 27 to move. The upper synchronous belt 27 drives the lower upper synchronous wheel 26, the upper lower synchronous wheel 28, the sorting roller 29 and the electromagnetic plate 210 to rotate. The upper lower synchronous wheel 28 drives the lower synchronous belt 212 to move. The lower synchronous belt 212 drives the lower lower synchronous wheel 28 and the grinding roller 211 to rotate.

[0036] Crushing blades 23 crush concrete waste, reducing it to smaller pieces. The pieces then fall from inlet box 11 through crushing box 16 into the area formed by electromagnetic plates 210. When electromagnetic plates 210 are energized, they attract the ferrous material. Sorting rollers 29 drive mounting plate 41 and second sensor 42 to rotate. When second sensor 42 aligns with first sensor 43, the corresponding electromagnetic plate 210 is de-energized, causing the ferrous material to fall out of outlet 19. The reduced pieces fall into converging hood 18 and then between two grinding rollers 211, where they are ground into granules.

The other end of each connecting rod 320 is rotatably connected to an L-shaped rod 321. The crossbar of each L-shaped rod 321 passes through the crushing box 16. Each L-shaped rod 321 is connected to a square groove plate 319, transforming the reciprocating swing into a symmetrical extrusion motion of the square groove plate 319. Two movable plates 318 are respectively disposed within each square groove plate 319, and adjacent movable plates 318 are rotatably connected. The grinding box 17 is provided with horizontal through-slots corresponding to the two connecting rods 320. By adopting gear meshing, the first round block 317 is set in the corresponding slide groove 316, so that when the power motor 33 rotates, the square groove plate 319 and the movable plate 318 can move. The adjacent movable plates 318 are vertically distributed. The square groove plate 319 and the movable plate 318 form a square structure with a side length that changes at all times. They work together with the extrusion cover 112 and the crushing box 16 to squeeze the smaller waste materials and make them smaller again, especially squeezing part of the concrete attached to the surface of iron materials such as steel bars and steel plates, so that the steel bars and steel plates are cleaner and convenient for subsequent collection.

[0038] The workflow of this embodiment is: The power motor 33 is controlled to rotate, and the power motor 33 drives the driving gear 34 to rotate.

The connecting rod 320 drives the L rod 321 to move back and forth. The L rod 321 drives the square groove plate 319 to move back and forth. The square groove plate 319 drives the movable plate 318 to move back and forth and expands along the square groove plate 319, and works together with the extrusion cover 112 and the crushing box 16 to squeeze the smaller waste to make it smaller again.

[0039] Example 3: This example further elaborates on Example 2. The central axis of the driving gear 34 is connected to a vertical shaft 313, which is in turn connected to a set of first crushing teeth 314. These first crushing teeth 314 are mated to the converging hood 18. The first crushing teeth 314 rotate continuously, re-crushing the extruded concrete to facilitate subsequent grinding. The first crushing teeth 314 form a shear gap with the inner wall of the converging hood 18, cutting the falling material flow, reducing the concrete to smaller pieces and protecting the roller surface.

[0040] The workflow of this embodiment is: The driving gear 34 drives the vertical shaft 313 and the first crushing teeth 314 to rotate. The first crushing teeth 314 rotate in the convergent cover 18 to crush the waste again.

[0041] Example 4: This example further elaborates on Example 3. The swing arm cross 37 is connected to the fixed end of the telescopic shaft 38. The vertical shaft 313 is disposed within the telescopic shaft 38. The free end of the telescopic shaft 38 is connected to a U-plate 39. The U-plate 39 matches the convergence cover 18 and is connected to a set of symmetrical second crushing teeth 315. The second crushing teeth 315 reciprocate, striking the falling concrete, reducing it to a smaller size for subsequent processing.

[0042] The grinding box 17 is provided with symmetrical vertical slots 110, each of which is provided with one end of a lifting rod 310. The free end bearing of the telescopic shaft 38 is connected to the lifting rod 310. Both ends of the lifting rod 310 are connected to an anti-slip plate 312. One of the anti-slip plates 312 is connected to an L-shaped mounting bracket 311, which is connected to a transverse slot 32. The eccentric points of the two upper lower synchronous wheels 28 are respectively connected to a second circular block 31, and the two second circular blocks 31 are respectively disposed in the transverse slot 32. By disposing the second circular blocks 31 in the transverse slot 32, the second crushing teeth 315 can be moved in the height direction, driving the concrete in the convergence cover 18 to move, facilitating the crushing by the first crushing teeth 314.

[0043] The workflow of this embodiment is: The swing arm cross 37 drives the telescopic shaft 38, the U-plate 39, and the second crushing tooth 315 to rotate reciprocatingly. The upper lower synchronous wheel 28 drives the second round block 31 to swing in the transverse groove 32. The second round block 31 drives the transverse groove 32 to move back and forth. The transverse groove 32 drives the L mounting frame 311 and the anti-slip plate 312 to move back and forth. The anti-slip plate 312 drives the lifting rod 310 to move back and forth in the vertical groove 110. The lifting rod 310 drives the free end of the telescopic shaft 38 to move back and forth in the height direction.

[0044] This device uses the first processing component 2 to process concrete waste and separate ferrous metal materials. The crushing roller 22 and the crushing blade 23 work together to crush large pieces of concrete into small pieces. Some concrete attached to the surface of ferrous materials such as steel bars and steel plates is attracted by the electromagnetic plate 210. When the second sensor 42 and the first sensor 43 are in the same position, the corresponding electromagnetic plate 210 is controlled to be de-energized, causing the ferrous materials to fall from the outlet 19 and achieve separation of the ferrous materials. Then, the small pieces of concrete are ground into granules by the grinding roller 211, realizing the recycling and processing of concrete waste, improving work efficiency, and realizing the comprehensive utilization of concrete waste.

[0045] When the power motor 33 of this device rotates, the square groove plate 319 and the movable plate 318 realize reciprocating motion, and the adjacent movable plates 318 are distributed vertically. The square groove plate 319 and the movable plate 318 form a square structure whose side length changes at all times, and work together with the extrusion cover 112 and the crushing box 16 to squeeze the smaller waste materials to make them smaller again, especially to squeeze part of the concrete attached to the surface of iron materials such as steel bars and steel plates, so that the steel bars and steel plates are cleaner and convenient for subsequent collection; the first crushing teeth 314 keep rotating to crush the squeezed concrete again, which is convenient for subsequent grinding; the second crushing teeth 315 move along the height direction, driving the concrete in the convergence cover 18 to move, which is convenient for the first crushing teeth 314 to crush.
