Filter plates 10 are movably connected to the upper end surfaces of the left and right connecting plates 12. In order to enable the uncrushed waste to be crushed for the second time, openings 11 are opened on the upper and lower sides of the central axis of the right end surface of the crushing box 1. The upper opening 11 facilitates the uncrushed waste to fall onto the upper part of the crushing roller 7, and the lower opening 11 facilitates the uncrushed waste to enter the interior of the feeding device 4.

[0029] See also Figure 3 In order to ensure that the uncrushed waste can enter the lower opening, the cross-section of the filter plate 10 is V-shaped, ensuring that the uncrushed waste can roll to the right, and the middle of the right end surface of the filter plate 10 corresponds to the lower opening 11, thereby ensuring that the uncrushed waste enters the inner cavity of the lower opening 11.

[0030] See also Figure 3 In order to ensure the rotation of the crushing roller 7 and the rolling roller 9, and to crush and roll the waste line, a transmission device 5 is composed of a sprocket 51, a chain 52, a drive motor 53 and a limit plate 54. The upper fixed shaft 6 and the lower fixed shaft 8 are each provided with three groups. The ends of the upper fixed shaft 6 and the lower fixed shaft 8 are fixedly connected with sprockets 51, and the outsides of the upper sprocket 51 and the lower sprocket 51 are movably connected with chains 52.

[0033] See also Figure 3 In order to filter quickly, telescopic springs 13 are evenly fixedly connected to the upper end surfaces of the left and right connecting plates 12, and the upper end of the telescopic spring 13 is fixedly connected to the lower end surface of the filter plate 10, ensuring that the crushed waste falls on the upper end surface of the filter plate 10, with a knocking force to shake off the crushed waste powder, and the waste powder enters the inner cavity of the storage box 2.

[0034] Working principle: When in use, the staff brings the NdFeB waste into the feed port 3, uses the external power connection to start the drive motor 53, and the drive motor 53 drives the sprocket 51 in the middle to rotate, which is driven by the chain 52 to drive the three sets of crushing rollers 7 and the rolling roller 9 to rotate, ensuring that the NdFeB waste is quickly broken. The broken waste is rolled by the rolling roller 9 and turned into powder of different sizes. The powdered waste falls on the upper end surface of the filter plate 10, which has the power of knocking, and the crushed waste powder is shaken. The waste powder falls through the filter plate 10 and enters the inner cavity of the storage box 2, while the larger granular powder waste passes through the filter plate 10 and enters the inner cavity of the lower opening 11. The motor 46 is started, and the motor 46 drives the rotating shaft 43 to rotate. The rotating shaft 43 drives the spiral blade 42 to rotate. The spiral blade 42 drives the large granular powder waste to the upper part of the inner cavity of the feeding barrel 44. The waste falls through the upper opening 11 and falls on the upper part of the crushing roller 7. It is crushed again by the crushing roller 7 and the rolling roller 9, which effectively improves the crushing efficiency and saves labor.
