[0026] Working principle:

[0027] The garbage is put into the crushing box 4, and the crushing motor 2 works, and the crushing shaft 3 crushes the garbage; after crushing, the garbage enters the separation cylinder 5; the waste metal in the soil residue is adsorbed by the adsorption shaft 20 to achieve separation; the driving motor 9 works, and under the gear transmission, the driving ring gear 10 rotates, and then the cooperating electric cylinder 11 also drives the cooperating end plate 12 to rotate, and further, the rotating end plate 102 follows the rotation, and the adsorption shaft 20 makes a circular motion on the inner side of the separation cylinder 5, and under the gear transmission and belt transmission, the adsorption shaft 20 rotates; the rotation of the adsorption shaft 20 can continuously change the adsorption area, that is, increase the contact area with the waste metal; the control electric cylinder 6 controls the extrusion arc block 7 to move to the end of the contact rod 23. When the adsorption shaft 20 makes a circular motion, when the contact rod 23 contacts the extrusion arc block 7, the adsorption shaft 20 slides axially, which can also change the adsorption area and improve the adsorption efficiency.

[0028] When the rotating end plate 102 rotates, the push plate 18 and the circulation frame 31 are in a coordinated relationship, that is, when the push plate 18 rotates following the rotating end plate 102, the circulation frame 31 also rotates. To ensure the stable coordination between the circulation frame 31 and the push plate 18, the extrusion plate 25 is driven to rotate by the rotating electric cylinder 24, and the extrusion plate 25 squeezes and pushes the pressure wheel 26, so that the limit rod 27 slides, and the push plate 18 and the circulation frame 31 are limited by one end of the limit rod 27; the circulation frame 31 rotates to perform a cyclic rolling treatment on the garbage in the separation drum 5, that is, the garbage is continuously turned over in the separation drum 5 and repeatedly contacts the adsorption shaft 20, that is, the waste metal in the garbage is subjected to multiple adsorption treatments to prevent the omission of a large amount of waste metal and improve the separation efficiency.

[0029] When the separation is completed, the cooperating electric cylinder 11 controls the cooperating end plate 12 to slide, that is, the cooperating end plate 12 is disengaged from one end of the separation cylinder 5, so that one end of the separation cylinder 5 is exposed, and the limit rod 27 releases the limit on the push plate 18 and the circulation frame 31; the push motor 13 works, pushing the screw 14 to rotate, so that the slip ring 16, the slide rod 17 and the push plate 18 slide, and the push plate 18 pushes the garbage in the separation cylinder 5 out of one end of the separation cylinder 5; through the pushing form, the garbage can be effectively cleaned and no large amount of garbage will remain inside the separation cylinder 5; after the garbage is cleaned, the adsorption shaft 20 releases the adsorption effect on the waste metal, and then the waste metal falls into the separation cylinder 5 and is also pushed out by the push plate 18.
