At this time, the dust-carrying gas passes through the filter 23, and the dust in the air is filtered by the filter 23, and clean air is discharged. When too much dust accumulates and the dust collection effect is poor, the dust storage drawer 26 can be pulled out from the inside of the exhaust box 25 to clean the accumulated dust so that the dust collection component 2 can work normally.

[0024] See also Figure 1 , Figure 3 and Figure 4 The shredder box assembly 3 includes a feed box 34, both sides of which are fixedly connected to a coarse crushing motor 32, a front side of the feed box 34 is fixedly connected to a plurality of L-shaped connecting plates 31, the output ends of the two coarse crushing motors 32 are rotatably connected to a coarse crushing roller 33 located inside the feed box 34, the coarse crushing motor 32 is electrically connected to an external power supply through a switch panel 6, an exhaust box 25 is fixedly installed between the plurality of L-shaped connecting plates 31, a classification assembly 4 includes a coarse and fine feeding port 41, one side of the bottom of the coarse and fine feeding port 41 is fixedly connected to a coarse feeding port 42, the other side of the bottom of the coarse and fine feeding port 41 is fixedly connected to a re-crushing port 43, a reducer 44 is provided on one side of the coarse and fine feeding port 41, a distributing shaft 45 is fixedly connected to the output end of the reducer 44, and the distributing shaft 45 is rotatably connected to the bottom of the inner cavity of the coarse and fine feeding port 41, and a shielding plate 46 is fixedly connected to the surface of the distributing shaft 45;

[0028] When the embodiment of the present application is in use: after the waste paper enters the feed box 34, the two coarse crushing motors 32 drive the coarse crushing rollers 33. Under the rotation of the coarse crushing rollers 33, the waste paper entering the feed box 34 is broken into shredded paper pieces of a certain size, and then directly discharged to the outside through the coarse material opening 42. If shredded paper pieces of smaller sizes are required, the switch controlling the classification component 4 on the switch panel 6 is turned on, and the reducer 44 drives the material distribution shaft 45 to rotate, thereby causing the shielding plate 46 to move to cover the coarse material opening 42. Under normal circumstances, the shielding plate 46 will cover the coarse material opening 42 or the secondary crushing opening 43, and it can be adjusted according to the usage, so that the initially crushed paper pieces will be discharged from the secondary crushing opening 43, and the secondary crushing opening 43 will be discharged. The shredded paper pieces discharged from the shredding opening 43 fall into the fine shredding box 53, and the fine shredding motor 51 drives the secondary shredding roller 52. Under the action of the secondary shredding roller 52, the shredded paper pieces are secondary processed and broken into smaller pieces of paper. At the same time, the dust collection component 2 starts to work, and the suction fan 24 starts to work, and the dust generated when the machine is working is sucked in through the dust cover 21 and transported through the dust pipe 22. At this time, the dust-carrying gas passes through the filter 23, and the dust in the air is filtered by the filter 23, and the clean air is discharged. When the dust accumulates too much and the dust collection effect is poor, the dust storage drawer 26 can be drawn out from the inside of the exhaust box 25 to clean the accumulated dust so that the dust collection component 2 can work normally.
