The feed port 2 is irregular in shape, and is mainly divided into two sections, one section is trapezoidal, and the other section is arc-shaped, and the two flip plates 14 are arranged inside the arc-shaped section. When the rotating shaft 15 drives the flip plates 14 to rotate, the movement trajectories of the two flip plates 14 are arc-shaped, and the outer diameters of the movement trajectories of the two flip plates 14 are smaller than the inner diameters of the arc-shaped section of the feed port 2, so that the flip plates 14 can be rotated. The rotating plate 14 is turned over inside the feed port 2, and when the top surface of the turning plate 14 is not subjected to force, the two turning plates 14 are always in a horizontal state, and block the opening at the connection between the feed port 2 and the inside of the machine body 1, so as to prevent the small parts of the scrap metal from bursting out of the outside of the machine body 1 when the scrap is shredded, causing safety hazards. The inner wall of the machine body 1 is symmetrically connected with the guide plates 5, and the surfaces of the guide plates 5 are inclined and the two guide plates 5 are arranged below the crushing rollers 4, so that the shredded scrap metal can be transported downward;
[0028] When using the device, the device is placed at a designated position, and the scrap metal is placed inside the feed port 2. At this time, the top surface of the flip plate 14 is subjected to pressure, and the flip plate 14 will be deflected by the rotation of the rotating shaft 15, so that the scrap metal can fall into the inside of the machine body 1. When the top surface of the flip plate 14 is not subjected to force, the flip plate 14 will return to its original position, thereby preventing subsequent fine materials from bursting out and causing safety hazards. The scrap metal falling into the machine body 1 will fall between the two crushing rollers 4, and the crushing motor 19 will be started. The crushing motor 19 drives the bidirectional rotating rod 16 to rotate, and the bidirectional rotating rod 16 drives the two worm gears 17 to rotate. The two worm gears 17 drive the two rotating rods 16 to rotate, and the two rotating rods 16 drive the two crushing rollers 4 to rotate at the same speed and in opposite directions, so that the scrap metal can be shredded, and the shredded scrap metal will fall to the bottom of the inside of the machine body 1 under the guidance of the guide plate 5;
[0029] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the interior of the machine body 1 is provided with a cleaning assembly for cleaning the shredded scrap metal, and the cleaning assembly is composed of a cleaning brush 8, a belt 7 and a rotating motor 6, wherein two cleaning brushes 8 are placed inside the machine body 1, and one end of the cleaning brush 8 extends out of the outside of the machine body 1, and a section of the cleaning brush 8 is extended to be connected with the belt 7, the rotating motor 6 is fixedly mounted on the outer surface of the machine body 1 through a fixing frame, and the output end of the rotating motor 6 is connected to one of the cleaning brushes 8, so that the rotating motor 6 can be driven to drive one of the cleaning brushes 8 to rotate, and the cleaning brush 8 can drive the other cleaning brush 8 to rotate through the belt 7, and then the two cleaning brushes 8 can be driven to rotate at the same time to clean the shredded scrap metal, a drain plate 12 is provided below the two cleaning brushes 8, and a lifting assembly is provided on the bottom surface of the drain plate 12, and the lifting assembly is composed of a slider 22 and an electric push rod 23, wherein the two electric push rods 23 are retractable The ends are symmetrically connected to the bottom surface of the drain plate 12, and the sliders 22 are fixedly connected at the four corners of the drain plate 12. The inner wall of the body 1 is symmetrically provided with moving grooves 13, and the sliders 22 are placed inside the moving grooves 13 and slidably connected thereto, so that when the electric push rod 23 drives the drain plate 12 to move up and down, the drain plate 12 can drive the sliders 22 to slide up and down inside the moving grooves 13, so as to ensure the stability of the drain plate 12 when it moves up and down. A through hole 11 is provided on the inner wall of the body 1, and a valve 20 is provided on the outer surface of the body 1, and the valve 20 is connected to the through hole 11, so that the valve 20 can be opened to discharge the cleaning water inside the body 1 to the outside of the body 1, and a water inlet 9 is provided on one side of the body 1 for pouring clean water and cleaning liquid for cleaning old metals into the interior of the body 1, and a perspective window 21 for viewing the cleaning condition of the scrap metal of the body 1 is provided on the outer surface of the body 1, and a sealing door 3 is connected to the outer surface of the body 1 through a hinge;
[0030] It is worth noting that the through hole 11 of the device is arranged below the movable groove 13. When the drain plate 12 drops to the lowest point, the through hole 11 is still placed below the drain plate 12. This prevents the shredded scrap metal on the top surface of the drain plate 12 from blocking the through hole 11 and affecting the drainage process when the machine body 1 is drained. When the drain plate 12 drops to the lowest point, the position of the drain plate 12 inside the machine body 1 is opposite to the sealing door 3, so that it is convenient for the staff to open the sealing door 3 and remove the shredded scrap metal on the top surface of the drain plate 12.

The rotating cleaning brush 8 can clean the surface of the shredded scrap metal, thereby ensuring the cleanliness of the scrap metal and facilitating the subsequent staff to recycle it. After the cleaning is completed, the valve 20 can be opened to discharge the waste water inside the machine body 1. After the discharge is completed, the electric push rod 23 is started, and the electric push rod 23 lowers the drain plate 12 to the lowest point. By opening the sealing door 3, the shredded and cleaned scrap metal can be taken out;
[0032] Specific working principle: the device is placed at a designated position, and the scrap metal is put into the machine body 1 through the feed port 2. The opening between the feed port 2 and the machine body 1 is blocked by the flip plate 14 to prevent fine materials from bursting out of the machine body 1 during the shredding process, thereby reducing potential safety hazards. The shredding motor 19 is started, and the shredding motor 19 drives the bidirectional worm 18 to rotate, and the bidirectional worm 18 drives the two worm wheels 17 to rotate. The two worm wheels 17 drive the two shredding rollers 4 to rotate in the opposite direction through the rotating rod 16. The shredding rollers 4 that rotate in the opposite direction can shred the scrap metal, and the shredded scrap metal falls to the drain plate 1 under the guidance of the guide plate 5. 2, clean water and cleaning liquid are poured into the interior of the body 1 through the water inlet 9 in advance, and the rotating motor 6 is started, and the rotating motor 6 drives two cleaning brushes 8 to rotate through the belt 7, and the cleaning and rotating cleaning brush 8 can clean the shredded scrap metal, and the cleaning condition of the scrap metal can be checked through the perspective window 21. After cleaning, the waste water inside the body 1 is discharged to the outside of the body 1 by opening the valve 20, and the electric push rod 23 is started, and the electric push rod 23 drives the drain plate 12 to drop to the lowest point. By opening the sealing door 3, the shredded and cleaned scrap metal can be taken out, which is convenient for the staff to recycle it.
