The first arc surface 2414 matches and fits with the strip grooves 2411, and the second arc surface 2415 and the outer peripheral wall of the rotating roller 2401 are on the same cylindrical surface. The two transmission shafts 2413 on the push rod 2412 correspond to the two rotating rings 2410 respectively. The transmission shaft 2413 passes through the rotating ring 2410, and the transmission shaft 2413 is rotatably connected with the rotating ring 2410; Among the two transmission shafts 2413 on the push rod 2412, a rotating gear 2416 is installed on one of the transmission shafts 2413; A protective cover 2417 is fixedly provided on the outer wall of the housing 21, a fixed shaft 2418 is fixedly provided inside the protective cover 2417, the fixed shaft 2418 is coaxially arranged with the rotating roller 2401, a fixed gear 2419 is installed on the fixed shaft 2418, and each rotating gear 2416 is meshed with the fixed gear 2419; It also includes an extrusion mechanism 25, which is located below the rotating roller 2401. The extrusion mechanism 25 includes a fixed tube 2501, which is parallel to the rotating roller 2401. The fixed tube 2501 is fixed through both sides of the shell 21, and the fixed tube 2501 passes through the filter 2402. A slide groove 2502 is provided on the side of the fixed tube 2501 away from the rotating roller 2401. A sliding connection is provided in the slide groove 2502 with an extrusion rod 2503, and a moving system is connected to the extrusion rod 2503. The moving system is used to drive the extrusion rod 2503 to move toward or away from the rotating roller 2401, wherein the moving system is two oil cylinders 2504, and the piston ends of the two oil cylinders 2504 are fixedly connected to the extrusion rod 2503 respectively; The squeezing mechanism 25 further includes two rotating shafts 2505, which are symmetrically arranged on both sides of the fixed tube 2501, and the rotating shafts 2505 are rotatably connected to the housing 21. The rotating shafts 2505 are parallel to the fixed tube 2501, and the rotating shafts 2505 pass through the filter screen 2402. The rotating shafts 2505 are provided with squeezing parts 2506, and the rotating shafts 2505 are hinged to the squeezing rods 2503. Specifically, the extrusion rod 2503 is fixedly connected to a lifting block 2507, and the lifting block 2507 is connected to two connecting rods 2508, and the two connecting rods 2508 correspond to the two rotating shafts 2505 one by one. The rotating shaft 2505 is hinged to the lifting block 2507 through the connecting rods 2508, and the connecting rods 2508 are arranged obliquely; A method for shredding and separating an electrical box comprises the following steps: Step S1: Loading The material is conveyed from the feed port 22 of the crusher 2 to the crusher 2 by the feeding conveyor 1; Step S2: Shredding the material The material is input from the feed port 22 and then enters the filter screen 2402 from the opening. The driving system causes the rotating shaft 2404 to drive the rotating roller 2401 to rotate. The rotation of the rotating roller 2401 drives the hammer head 2405 to rotate. The material is shredded by the rotation of the hammer head 2405. During the rotation of the rotating shaft 2404, the rotating ring 2410 is driven to rotate synchronously on the housing 21, and the push rod 2412 is driven to rotate synchronously through the transmission shaft 2413, and the rotating gear 2416 is rotated on the fixed gear 2419. Since the fixed gear 2419 is in a stationary state, the rotating gear 2416 drives the transmission shaft 2413 to rotate, and the rotation of the transmission shaft 2413 drives the push rod 2412 to rotate synchronously. In this way, the push rod 2412 rotates around the rotating roller 2401 while also rotating around the transmission shaft 2413 connected thereto; Among them, through calculation, when the push rod 2412 rotates around the transmission shaft 2413 connected thereto, the first arc surface 2414 of the push rod 2412 intermittently protrudes to the outside of the rotating roller 2401; During the material shredding process, the material is easily stuck between two adjacent hammers 2405 along the circumferential direction of the rotating roller 2401, and the stuck material is pushed out through the first arc surface 2414, which facilitates the contact between the material and the hammer 2405, thereby improving the material shredding effect and the work efficiency; In addition, when the shredded material reaches the set volume, it passes through the filter screen 2402 and is discharged from the discharge port 23. When the shredded material has not yet reached the set volume, it is intercepted by the filter screen 2402, and after the hammer head 2405 hammers again and reaches the set volume, it passes through the filter screen 2402 and is discharged from the discharge port 23. Moreover, the extrusion rod 2503 is driven by the moving system to move toward or away from the rotating roller 2401. When the material that has not reached the set volume after being shredded falls on the inner wall of the filter screen 2402, the extrusion rod 2503 moves away from the rotating roller 2401, and the extrusion rod 2503 and the filter screen 2402 squeeze and shred the material that has not reached the set volume after being shredded. After reaching the set volume, the material passes through the filter screen 2402 and is discharged from the discharge port 23, thereby further improving the shredding efficiency. Secondly, when the squeezing rod 2503 moves in a direction away from the rotating roller 2401, it drives the lifting block 2507 to move synchronously. The movement of the lifting block 2507 drives the rotating shaft 2505 to rotate a set angle through the connecting rod 2508. The rotation of the rotating shaft 2404 drives the squeezing part 2506 to rotate synchronously. At this time, the squeezing part 2506 and the squeezing rod 2503 squeeze and shred the materials that have not reached the set volume, thereby further improving the shredding efficiency. Step S3: Discharging and Sorting The material discharged from the discharge port 23 is conveyed to the second unloading conveyor 5 by the first unloading conveyor 3, and at the same time, the magnetic material in the material on the first unloading conveyor 3 is sorted out by the magnetic separator 4; Step S4: Unloading The sorted materials are transported to the next process through the second unloading conveyor 5; Here, it should be noted that when the push rod 2412 rotates to the lower part of the rotating roller 2401 and faces the fixed tube 2501, the first arc surface 2414 pushes the material between two adjacent hammer heads 2405, and the push rod 2412 and the fixed tube 2501 can also clamp and shred the material, further improving efficiency; To sum up, during the process of shredding materials, when the hammer head 2405 rotates around the transmission shaft 2413 connected thereto through the push rod 2412, the first arc surface 2414 of the push rod 2412 intermittently protrudes to the outside of the rotating roller 2401, so that the first arc surface 2414 pushes out the stuck material, making it easier for the material to contact with the hammer head 2405, thereby improving the material shredding effect and improving the work efficiency. Secondly, through the reciprocating movement of the extrusion rod 2503, the extrusion rod 2503 and the filter screen 2402 intermittently shred the material that has not reached the set volume, thereby further improving the material shredding efficiency. In addition, during the reciprocating movement of the extrusion rod 2503, the extrusion extrusion part 2506 also swings back and forth, so that the extrusion part 2506 and the extrusion rod 2503 extrude and shred the material that has not reached the set volume, thereby further improving the shredding efficiency.
