[0002] With the acceleration of urbanization and the booming development of the construction industry, the amount of construction waste generated is increasing day by day. Among them, construction waste boards account for a considerable proportion. These waste boards include wood boards, metal boards, plastic boards and composite boards, etc. They are discarded in large quantities during the demolition, decoration or renovation of buildings. In the process of processing construction waste boards, the metals and light plastics and other recyclable materials are screened out, which is of great significance for improving the resource recycling rate and reducing the processing cost.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Combined with appendix Figure 1 , 2 4. It can be seen that the machine includes a frame 1. A feed inlet 1.3 is opened on one side of the top of the frame 1 to facilitate the conveying of waste sheet metal. A discharge outlet 1.4 is opened at the lower end of the other end of the frame 1 to output the crushed material. Three pairs of crushing rollers 2 are rotatably arranged inside the frame 1. The crushing fineness of the three pairs of crushing rollers 2 gradually increases from top to bottom, so as to finely crush the waste sheet metal and simultaneously facilitate the extraction of waste metal and light plastic. A conveyor belt mechanism 3 is provided between each pair of crushing rollers 2. Conveyor belt mechanism 2 4, with a wind box 5 fixed on the inner side of the frame frame 1 above the conveyor belt mechanism 1 3. The wind box 5 has several air holes on its upper side. The wind box 5 is located below and to the side of the top crushing roller 2, and the wind direction of the wind box 5 is towards the air outlet 1.1, which is convenient for air separation of light plastics. The air outlet 1.1 is opened on the upper side of the frame frame 1 above the wind box 5. A protective frame 6 is fixed on the upper side of the air outlet 1.1. The conveyor plate 2 11 is fixed on the upper side of the frame frame 1 at the bottom of the protective frame 6, which is convenient for conveying the light plastic waste separated by air.

[0022] Combined with appendix Figure 2 , 3 It can be seen that an opening 1.2 is provided on the upper side of the frame 1 above the conveyor belt mechanism 4. The two ends of the upper side of the opening 1.2 are fixed with hinge frames 7. A rotating roller 8 is rotatably provided between the hinge frames 7 to facilitate the rotation and adsorption of the magnetic rods 9. Several magnetic rods 9 are inserted into the side of the rotating roller 8. A conveyor plate 10 is fixed on the upper side of the frame 1 next to the rotating roller 8. The end of the conveyor plate 10 contacts the surface of the magnetic rods 9 to facilitate the scraping off and output of the metal adsorbed by the magnetic rods 9.

[0023] The working principle of this application is as follows: When crushing and screening construction waste, the waste board is conveyed to the inlet 1.3 through an external conveying structure. It is initially crushed by the first set of crushing rollers 2 to cut the waste board. Then, the air box 5 blows air onto the waste board to blow the light plastic towards the air outlet 1.1, and then output through the second conveyor plate 11. The initially crushed waste board is then conveyed to the middle crushing roller 2 through the first conveyor belt mechanism 3 for secondary crushing. The crushed waste is then conveyed to the third set of crushing rollers 2 through the second conveyor belt mechanism 4. During the conveying process, the rotating roller 8 drives several magnetic rods 9 to attract the metal in the waste and scrape it off through the first conveyor plate 10, thereby removing the metal from the waste. Finally, after being crushed by the third set of crushing rollers 2, it is output from the outlet 1.4.
