[0042] It should be noted that when the first floating plate 52 and the second floating plate 54 are close to each other, the spherical recyclable items can pass through the screening hole 51 and the floating hole 56, and the spherical recyclable items are not easily crushed by the two crushing rollers 3. Specifically, the spherical recyclable items push the floating hole 56 to move the first floating plate 52 and the second floating plate 54. After the floating hole 56 is pushed open, the first floating plate 52 and the second floating plate 54 are closed again under the action of the telescopic spring 58, and the spherical recyclable items enter the screening hole 51, thereby retaining the spherical recyclable items above the pressing plate 48, isolating the spherical items between the pressing plate 48 and the fixed plate 46, and sorting out the spherical items does not affect other items from entering the gap of the crushing roller 3.
