Larger debris is taken out separately for secondary crushing.

[0025] During the process of crushing waste materials by the crushing equipment 4, the waste materials will generate dust which will float to the top of the recycling box 3. The vacuum cleaner 506 will inhale air, so that the suction nozzle 505 will suck the dust into the hollow box 504, and then the dust will enter the vacuum cleaner 506 through the suction tube 507 to prevent the dust from polluting the air. When the device is not in use, the screw rod 502 is rotated to make the sleeve 503 descend and drive the hollow box 504 to descend and contact the top of the recycling box 3, which reduces the occupied space and can prevent impurities in the external air from entering the recycling box 3. The driving motor 601 drives the connecting rod 602 to rotate, so that the eccentric wheel 608 intermittently hits the screen box 607, and the slider 605 slides on the slider 604 to limit the screen box 607, so that the screen box 607 vibrates up and down, which can accelerate the screening speed of the crushed material in the screen box 607 and improve the screening effect.
