One end of the connecting pipe 210 away from the second fixed hopper 29 is fixedly connected with a collection box 211. The bottom surface of the collection box 211 is fixedly connected with an exhaust fan 212. When the exhaust fan 212 operates, it will extract the air inside the collection box 211.

[0029] The collection box 211 is fixedly connected to the outer surface of the fixed box 21. The inner wall of the collection box 211 is slidably connected with a sealing frame 213. The inner wall of the sealing frame 213 is fixedly connected with a filter screen 214. The filter screen 214 can filter and collect lightweight materials such as wood chips and plastics onto the filter screen 214.

[0030] The inner wall of the fixed box 21 is fixedly connected with a fixing plate 24. A motor is arranged on the fixing plate 24 to provide power for the rotation of the eccentric wheel 25. The upper surface of the fixing plate 24 is fixedly connected with two support seats 216. Both of the two support seats 216 are rotatably connected to the outer surface of the eccentric wheel 25. The support seats 216 play a supporting role for the rotation of the fixing plate 24.

[0031] The upper surface of the fixing plate 24 is fixedly connected with springs 215. One end of each of the two springs 215 away from the fixing plate 24 is fixedly connected to the outer surface of the swing plate 23. The arrangement of the springs 215 can reset the swing plate 23.

[0032] Please refer specifically to Figure 1 and Figure 2 , above the fixed box 21, a crushing mechanism 3 is provided. The crushing mechanism 3 includes a crushing box 31 fixedly connected to the upper surface of the fixed box 21. Two symmetrically arranged crushing rollers 32 are rotatably connected to the inner wall of the crushing box 31. Two motors are arranged on the crushing box 31 to provide power for the rotation of the crushing rollers 32. The two crushing rollers 32 rotate in opposite directions. The rotation of the two crushing rollers 32 can crush construction waste.

[0033] Please refer specifically to Figure 1 and Figure 2, a magnetic metal separation mechanism 4 is provided inside the screening frame 1. The magnetic metal separation mechanism 4 includes a magnet conveyor belt 43 and a fixed frame 41 fixedly connected to the inner wall of the screening frame 1. Two conveyor rollers 42 are rotatably connected to the inner wall of the fixed frame 41, and the two conveyor rollers 42 are drivingly connected through the magnet conveyor belt 43. Magnets are arranged at equal distances on the magnet conveyor belt 43, which can adsorb magnetic metals in the recycled bone powder.

[0035] When the present utility model is in use: Construction waste enters the crushing box 31, and the crushing roller 32 rotates to crush the construction waste. The crushed material falls downward through the inclined plate 22. Control the eccentric wheel 25 to rotate. The eccentric wheel 25 will lift the swing plate 23, and at the same time, the spring 215 will reset the swing plate 23, so that the swing plate 23 swings. The swing plate 23 will disperse the material. Control the blower 28 and the exhaust fan 212 to operate. The blower 28 blows air to the air-permeable plate 26 through the first fixed hopper 27, blowing up light materials such as wood chips and plastics. At the same time, when the exhaust fan 212 operates, it will suck in the wood chips and plastics through the connecting pipe 210 and the second fixed hopper 29. The wood chips and plastics will be collected on the filter screen 214, and then the material is discharged outside the fixed box 21 through the air-permeable plate 26. When the material falls on the magnet conveyor belt 43, the magnetic metals in the material will be adsorbed on the magnet conveyor belt 43. Then when the magnet conveyor belt 43 conveys the magnetic metals to the scraper frame 44, the magnetic metals will be scraped into the scraper frame 44 and discharged through the scraper frame 44. At the same time, the remaining material falls onto the screening frame 1, and the material slides on the inclined screening frame 1. The fine bone powder will pass through the screening frame 1 and fall, and the coarse bone powder is discharged from the left side of the screening frame 1. This device can separate and recycle light materials such as wood chips and plastics in construction waste, improve the recycling efficiency, and improve the quality of recycled aggregates.
