Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The area where the material is located has strong magnetism. When the material passes through the magnetic suction hole 5, the magnetic substance in the material is adsorbed on the connecting plate 6. The connecting plate 6 is connected to the inclined portion 4 by a hinge. The hinge can be a buffer hinge. Through the connection plate 6, the high-strength magnetic rod 7 and the magnetic suction hole 5, when the material passes through the vertical portion 3 and enters the inclined portion 4, when the material slides on the inclined surface, the huge magnetic adsorption force carried by the high-strength magnetic rod 7 will completely adsorb the magnetic substance in the material on the connecting plate 6. Compared with the electromagnet and other methods that require an external power supply, the non-powered magnetic suction method is simpler and more efficient, and the material processing speed is also greatly improved;

[0027] Considering that the magnetic material on the connecting plate 6 needs to be cleaned regularly, which is very time-consuming and labor-intensive, affecting the material transmission efficiency, a mounting plate 8 is fixed on the side wall of the feed hopper 2, a servo motor 9 is fixed on the mounting plate 8, a control unit is arranged inside the servo motor 9 to control the forward and reverse rotation and the opening time, a rotating shaft is coaxially fixed to the output end of the servo motor 9, a reel 10 is coaxially fixed to the rotating shaft, a steel wire rope 11 is wound around the reel 10, and a connecting block is fixed to the end of the connecting plate 6 away from the hinge 12, a connecting rod 13 is slidably connected to the connecting block 12, a pull ring 14 is sleeved on the connecting rod 13, and one end of the steel wire rope 11 away from the drum 10 is fixedly connected to the pull ring 14. Through the servo motor 9, the steel wire rope 11 and the connecting rod 13, after a certain period of time, the feed hopper 2 stops feeding, the servo motor 9 rotates, and the steel wire rope 11 slowly releases the restriction on the connecting plate 6. The connecting plate 6 rotates under the action of gravity. After the connecting plate 6 is opened, the worker can directly remove the magnetic material attached to the connecting plate 6;

[0028] In order to further improve the cleaning efficiency on the connecting plate 6, two symmetrically distributed slide grooves 15 are provided on the connecting plate 6. The cross-section of the slide groove 15 is rectangular. The slide groove 15 is located on both sides of the magnetic hole 5. The connecting plate 6 is slidably connected with a scraper 16 located in the magnetic hole 5. It should be noted that in order to prevent interference between the scraper 16 and the magnetic hole 5 when the connecting plate 6 is turned over, a certain distance is retained between the scraper 16 and the edge of the magnetic hole 5. The length of the scraper 16 is consistent with the width of the magnetic hole 5.

The rotating drum 18 is located on the inclined portion 4, and two symmetrically distributed connecting cylinders 19 are fixed on the inclined portion 4. The two connecting cylinders 19 are respectively located at both ends of the rotating drum 18. The connecting cylinder 19 is connected to the rotating drum 18 through a torsion spring. Through the scraper 16, the telescopic rod 17 and the rotating drum 18, when the connecting plate 6 rotates, the rotating drum 18 rotates accordingly driven by the torsion spring. When the connecting plate 6 rotates a certain angle, the telescopic rod 17 pulls the scraper 16 to clean the connecting plate 6. When the scraper 16 pushes the magnetic material out of the coverage area of ​​the high-strength magnetic rod 7, the magnetic material slides out of the connecting plate 6 under the action of gravity.

[0032] Furthermore, the feed hopper 2 is made of wear-resistant alloy.

[0033] When the utility model is used:

[0034] First, when the material passes through the vertical portion 3 and enters the inclined portion 4, the material slides on the inclined surface, and the huge magnetic adsorption force carried by the high-strength magnetic rod 7 completely adsorbs the magnetic substances in the material on the connecting plate 6;

[0035] Then, at regular intervals, the feed hopper 2 stops feeding, the servo motor 9 rotates, the wire rope 11 slowly releases the restriction on the connecting plate 6, the connecting plate 6 rotates under the action of gravity, and the rotating drum 18 rotates accordingly driven by the torsion spring. When the connecting plate 6 rotates a certain angle, the telescopic rod 17 pulls the scraper 16 to clean the connecting plate 6;

[0036] Secondly, after the scraper 16 pushes the magnetic material out of the coverage area of ​​the high-strength magnetic rod 7, the magnetic material slides out of the connecting plate 6 under the action of gravity;

[0037] Finally, the servo motor 9 rotates in the reverse direction, the reel 10 reels the wire rope 11, the connecting plate 6 is reset under the drive of the pull ring 14, and the feed hopper 2 continues to discharge materials.
