When the pressure knife 17 is moved to one side of the metal iron barrel 7 by the force of the cylinder 14, the fixed block 15 and its connecting components will also move to the metal The iron barrel 7 moves on one side. When the pressing knife 17 squeezes the metal iron barrel 7, the electric hydraulic rod 22 drives the wheel frame 23 to rotate around the rotating shaft of the rotating seat 25, so that the movable plug rod 26 is in a horizontal state. At this time, the guide wheel 24 contacts the inclined plate of the baffle 13. Under the pressure of the guide wheel 24, the bottom of the baffle 13 tends to move toward the inner wall of the feed hopper 4. The metal iron barrel 7 will be flattened by the pressing knife 17 under the common limit of the feed hopper 4, the baffle 13, the baffle rod 12 and the top plate 18, so as to avoid the baffle 13 from turning over when the metal iron barrel 7 is flattened, causing the metal iron barrel 7 to fall from the bottom of the baffle 13 before being flattened.

After the metal iron barrel 7 is flattened, the pressure knife 17 and its components are retracted by the cylinder 14, and at the same time, the electric hydraulic rod 22 drives the wheel frame 23 to rotate upward, so that the guide wheel 24 contacts the vertical plate of the baffle 13, and the elastic force of the return spring 27 squeezes the top of the baffle 13, so that the top of the baffle 13 rotates toward the side of the feed hopper 4, so that the opening between the bottom of the baffle 13 and the feed hopper 4 becomes larger, so that the flattened metal iron barrel 7 automatically falls above the crushing blade 11 by gravity.

[0050] When the metal iron barrel 7 is recycled and crushed, the metal iron barrel 7 is fed and conveyed by the feeding conveyor belt 6. During the conveying process, it is positioned by the block 8 and the magnet bar 9. After the metal iron barrel 7 is conveyed between the feed hopper 4 and the baffle 13, the cylinder 14 drives the pressure knife 17 to move to one side of the metal iron barrel 7. The metal iron barrel 7 is flattened by the pressure of the pressure knife 17 to destroy the cylindrical structure of the metal iron barrel 7, so that the crushing blade 11 can quickly bite the metal iron barrel. The metal iron barrel 7 is crushed by the rotation of the crushing blade 11 without manual flattening, which effectively reduces the workload. By automatically flattening the iron barrel, the crushing efficiency of the iron barrel can be effectively improved.
