[0032] A magnetic mechanism is provided inside the box 1 above the first conveyor belt 5;

[0033] A material shifting mechanism is provided between the first baffles 3 and above the first conveyor belt 5 .

[0034] The material shifting mechanism includes a fourth rotating shaft 10, which is rotatably installed between the first baffle plates 3 and above the first conveyor belt 5 through a bearing, a shifting rod 11 is fixed to the outer wall of the fourth rotating shaft 10, the end of the fourth rotating shaft 10 passes through the first baffle plate 3 and is fixed with a first gear 12, a second gear 13 is meshed with the bottom of the first gear 12, and the inner wall of the second gear 13 is fixedly connected to the outer wall of the first rotating shaft 2, and a transmission structure is formed between the fourth rotating shafts 10 through a pulley mechanism 24.

[0035] The fourth rotating shafts 10 are evenly spaced above the first conveyor belt 5 , and the levers 11 are evenly distributed with respect to the central axis of the fourth rotating shafts 10 , thereby increasing the area for the fourth rotating shafts 10 and the levers 11 to turn over the construction waste.

[0036] The diameter of the second gear 13 is five times the diameter of the first gear 12, which ensures that the rotation speed of the first gear 12 is greater than the rotation speed of the second gear 13, so that the first conveyor belt 5 transports construction waste at a slower speed, and the fourth rotating shaft 10 and the lever 11 rotate at a faster speed, so that the lever 11 can fully turn over the construction waste on the first conveyor belt 5.

[0037] The magnetic mechanism includes a fifth rotating shaft 14, and the fifth rotating shaft 14 is rotatably installed inside the box body 1 through a bearing, a first movable plate 15 is arranged on the outer side of the fifth rotating shaft 14, a first electromagnet 16 is fixed at the bottom of the first movable plate 15, and the first electromagnet 16 is located above the first conveyor belt 5, a second movable plate 17 is arranged on the outer side of the fifth rotating shaft 14, a second electromagnet 18 is fixed at the bottom of the second movable plate 17, ends of the first movable plate 15 and the second movable plate 17 both penetrate a limiting rod 19, an end of the limiting rod 19 is fixedly connected to the inner wall of the box body 1, an end of the fifth rotating shaft 14 penetrates the side wall of the box body 1 and is fixedly connected to the output end of the servo motor 20, and the outer wall of the servo motor 20 is fixed to the outer wall of the box body 1 through a mounting plate.

[0038] The fifth rotating shaft 14 is threadedly connected to the first movable plate 15 and the second movable plate 17, and the limiting rod 19 is slidably connected to the first movable plate 15 and the second movable plate 17, ensuring that when the fifth rotating shaft 14 rotates forward or reversely, the first movable plate 15 and the second movable plate 17 can move simultaneously, thereby allowing the first electromagnet 16 and the second electromagnet 18 to move simultaneously.

[0039] A discharge pipe 21 is fixed through the top of the box body 1, a storage bin 22 is fixed on the top of the discharge pipe 21, and the bottom of the discharge pipe 21 is located above the first conveyor belt 5. Through the discharge pipe 21, the crushed construction waste inside the storage bin 22 can be spread flat on the first conveyor belt 5.

[0040] Collecting boxes 23 are respectively arranged below the second rotating shaft 4 and the third rotating shaft 7 , so as to ensure that the construction waste on the first conveyor belt 5 and the second conveyor belt 8 can be collected in the two collecting boxes 23 .

[0041] In order to observe the situation inside the box 1 , a transparent observation window is installed on the box 1 .

[0042] Working principle: When the screening device for garbage disposal is used, the rotating motor 9 is first started, and then the rotating motor 9 drives the first rotating shaft 2 to rotate forward, and then the first rotating shaft 2 drives the first conveyor belt 5, the second rotating shaft 4, the second conveyor belt 8 and the third rotating shaft 7 to rotate forward at the same time. When the first rotating shaft 2 rotates forward, the first rotating shaft 2 drives the first gear 12 and the fourth rotating shaft 10 to rotate reversely through the second gear 13, and the fourth rotating shaft 10 drives several fourth rotating shafts 10 to rotate simultaneously through several pulley mechanisms 24, so that several fourth rotating shafts 10 drive several levers 11 thereon to rotate simultaneously;

[0043] Then, the crushed construction waste is poured into the storage bin 22, and then the crushed construction waste falls to the top of the first conveyor belt 5 through the discharge pipe 21. The crushed construction waste moves to the right along with the first conveyor belt 5, and at the same time, the first electromagnet 16 is started to generate magnetism, and the first electromagnet 16 absorbs metal waste in the construction waste. The rotating lever 11 fully turns the crushed construction waste, so that the metal waste pressed by the non-metallic waste can also be absorbed by the first electromagnet 16, so that the construction waste can be fully screened, and then the non-metallic waste moves to the right through the first conveyor belt 5 and finally falls into the collection box 23 for centralized collection;

[0044] When the bottom of the first electromagnet 16 absorbs too much metal garbage, the servo motor 20 is started. At this time, the servo motor 20 drives the fifth rotating shaft 14 to rotate. Since the fifth rotating shaft 14 is threadedly connected with the first movable plate 15 and the second movable plate 17, and the limit rod 19 is slidably connected with the first movable plate 15 and the second movable plate 17, the first movable plate 15, the first electromagnet 16, the second movable plate 17 and the second electromagnet 18 move backward at the same time until the second electromagnet 18 moves to the top of the first conveyor belt 5, and the first electromagnet 16 moves to the top of the second conveyor belt 8 at the back, and the energized second electromagnet 18 absorbs the metal garbage on the first conveyor belt 5, so that the second electromagnet 18 replaces the first electromagnet 16 to absorb the metal garbage on the first conveyor belt 5;

[0045] The first electromagnet 16 is powered off, the first electromagnet 16 loses its magnetism, and the metal waste adsorbed by the bottom of the first electromagnet 16 falls to the top of the second conveyor belt 8 at the back, and then the metal waste moves to the right along with the second conveyor belt 8 and falls into another collecting box 23 for centralized collection;

[0046] When too much metal waste is adsorbed by the bottom of the second electromagnet 18, the servo motor 20 is started in reverse, so that the second electromagnet 18 and the first electromagnet 16 move forward at the same time until the first electromagnet 16 is located above the first conveyor belt 5 and the second electromagnet 18 is located above the second conveyor belt 8 in front, and then the energized first electromagnet 16 adsorbs the metal waste on the top of the first conveyor belt 5 again, and the second electromagnet 18 is powered off, and the metal waste adsorbed by the bottom of the second electromagnet 18 falls to the top of the second conveyor belt 8 in front, and is collected inside the third collection box 23 as the second conveyor belt 8 falls. In summary, construction waste can be continuously screened, thus avoiding downtime and improving work efficiency.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
