A second recovery box 58 is arranged on the left side of the metal sorting device, and a third recovery box 59 is arranged on the right side of the metal sorting device; when the rotating plate 62 is inclined to the right, most of the construction waste falling from the blanking end of the third conveyor belt 54 is concrete blocks which cannot be adsorbed by the electromagnet and slide down to the third recovery tank 59 under the action of gravity; after working for a period of time, the driving cylinder 63 drives the rotating plate 62 to incline to the left, then the electromagnetic controller controls the electromagnet to be powered off, and the magnetic metal garbage on the surface of the rotating plate 62 falls into the second recycling box 58 along the rotating plate 62, so that the sorting of the metal garbage, concrete blocks and bricks is realized.

The working process is as follows: during operation, the crushed construction waste is conveyed by the feeding conveying device 1 and enters the machine body 2, firstly, the construction waste enters the throwing wheel device 3 along the feeding conveying belt 11, and the throwing wheel device 3 throws the construction waste to the primary sorting device at a constant speed. The arrangement of the throwing wheel device 3 enables the construction waste to be thrown more dispersedly, the blowing device is over against the thrown falling construction waste, the fan 45 blows the thrown falling construction waste to the first filter plate 41, the first filter plate 41 only enables fine sand to pass through, the fine sand passes through the first filter plate 41 and then enters the recovery channel 42, and the fine sand is sent out through the fine sand conveying belt 46; plastics, wood and the like with the same lighter weight and smaller particles (usually with the diameter of 2-7mm) flap on the left side of the first filter plate 41 under the action of the air blowing device, and are blocked by the first filter plate 41 and fall into the first recovery tank 43; the construction waste with larger volume and mass is less influenced by the blowing device, falls on the inclined guide plate 47 on the left side of the first recovery tank 43 and enters the water tank 51, plastic and wood with larger particles float on the surface of water after entering the water tank 51 and are blocked by the second filter plate, the construction waste sinking to the bottom of the water tank 51 is conveyed to the metal sorting device through the conveying belt mechanism, the metal sorting device is arranged at the blanking end of the third conveying belt 54, the metal waste is adsorbed by the electromagnet on the rotating plate 62, other waste falls into the third recovery tank 59, after working for a period of time, the driving cylinder 63 drives the rotating plate 62 to incline leftwards, then the electromagnet is controlled by the electromagnetic controller to be powered off, and the magnetic metal waste on the surface of the rotating plate 62 falls into the second recovery tank 58 along the rotating plate 62, so that the sorting of the metal waste, concrete blocks and bricks is realized.

The foregoing is illustrative of the best mode of the invention and details not described herein are within the common general knowledge of a person of ordinary skill in the art. The scope of the present invention is defined by the appended claims, and any equivalent modifications based on the technical teaching of the present invention are also within the scope of the present invention.
