[0022] The first separation unit comprises a second bracket 7, on which a second motor is fixedly mounted, a rotating shaft 8 is drivingly connected to the second motor, a fixing plate 9 is fixedly sleeved on the rotating shaft 8, and a strong magnetic plate 10 is fixedly mounted on one side of the fixing plate 9;

[0023] Both ends of the rotating shaft 8 are mounted on the second bracket 7 through the bearing seat. The rotating shaft 8 is supported at both ends by the bearing seat, thereby enhancing the stability of the movement of the rotating shaft 8.

[0024] The output shaft of the second motor is connected to a reducer 15, and the output shaft of the reducer 15 is connected to one end of the rotating shaft 8. The reducer 15 can better control the speed of the second motor to ensure that the rotating shaft 8 rotates at a low and uniform speed, thereby preventing the rotating shaft 8 from rotating too fast and causing the adsorbed metal to be separated from the strong magnetic plate 10 before the strong magnetic plate 10 rotates to its full position.

[0025] A third bracket 11 is arranged on the side of the second bracket 7 away from the conveyor belt 2, and a driving mechanism is arranged on the third bracket 11. A scraper plate 12 is arranged on the output end of the driving mechanism. The lower end of the scraper plate 12 is bent to one side, and its edge is gradually thinned from the inside to the outside. Such a structure is conducive to the scraper plate 12 to fit the surface of the strong magnetic plate 10 for scraping;

[0026] The driving mechanism includes a first driving cylinder fixedly arranged on the top of the third bracket 11, a support seat 14 is fixedly arranged on the telescopic end of the first driving cylinder, the support seat 14 is arranged in an L shape, a second driving cylinder is fixedly arranged on the other side of the support seat 14, and the telescopic end of the second driving cylinder is fixedly connected to the scraper plate 12;

[0027] A receiving box 13 is placed at the bottom of the third bracket 11 . The second separation unit has the same structure as the first separation unit and is located at both sides of the conveyor belt 2 .

[0028] Working principle: When the device is in use, after the construction waste crushed by the crushing box 1 falls onto the conveyor belt 2, the first motor controls the rotating material rod 6 to scatter the waste falling from the discharge port to avoid local accumulation. Then, when passing under the strong magnetic plate 10 of the first separation unit, the metal objects in the waste are adsorbed onto the strong magnetic plate 10. After a period of time, the second motor controls the strong magnetic plate 10 to rotate 180 degrees to the scraper plate 12, and at the same time, the strong magnetic plate 10 of the second separation unit is rotated to the top of the conveyor belt 2 to continue to adsorb metal objects. The driving mechanism controls the scraper plate 12 to scrape the metal objects adsorbed on the strong magnetic plate 10 of the first separation unit and drop them into the receiving box 13 below. In this cycle, the two strong magnetic plates 10 rotate alternately to the top of the conveyor belt 2 to adsorb metal objects, thereby achieving efficient metal separation.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
