[0024] A waste shredder that prevents dust from spilling out, such as Figure 1 and Figure 2 As shown, it includes a crushing box 1 and a crushing mechanism 2. The crushing mechanism 2 is installed through the inside of the crushing box 1. The crushing mechanism 2 is composed of a drive motor, a gear set and a crushing roller set. A sieve plate 3 is installed inside the crushing box 1 below the crushing mechanism 2. The sieve plate 3 is set with an inverted "V" shape. Collection boxes A4 are provided on both sides and below the crushing box 1. A feed hopper 5 is provided at the top of the crushing box 1.

[0025] See Figure 1 and Figure 2 It can be seen that the waste material is fed from the feed hopper 5 into the crushing box 1, so that the crushing mechanism 2 can be used to crush the waste material. At the same time, the crushed waste material is screened by the screen plate 3 below the crushing mechanism 2, and the screened waste material is collected by the collection box A4 for subsequent reuse.

[0026] See Figures 1-5 It is known that the inside of the pulverizing box 1 is provided with an anti-overflow mechanism 6 extending to the outside. The anti-overflow mechanism 6 includes a dust suction hood 601, a dust suction pipe assembly 602, a filter box 603, a filter plate 604, a fan blade 605, and a rotary motor 606. Dust suction hoods 601 are provided on both sides inside the pulverizing box 1. The filter box 603 is located at the rear end of the pulverizing box 1. The filter plate 604 is located on the inner side of the filter box 603. The filter plate 604 is designed with a circular structure, and the aperture of the two filter plates 604 decreases from front to back. The fan blade 605 is movably connected to the rear end of the filter box 603. The dust suction pipe assembly 602 is connected between the dust suction hood 601 and the filter box 603. The dust suction pipe assembly 602 is composed of an L-shaped pipe and a straight pipe. The rotary motor 606 is installed on the second mounting bracket at the rear end of the filter box 603. The output end of the rotary motor 606 is connected to the fan blade 605 through a coupling.

[0027] See Figures 1-5 As can be seen, since the dust collection hood 601 and the filter box 603 are connected by the dust collection pipe assembly 602, when the rotary motor 606 drives the fan blade 605 to rotate, the fan blade 605 drives the airflow, so that the dust in the shredder 1 can be absorbed and introduced into the filter box 603 through the cooperation of the dust collection hood 601 and the dust collection pipe assembly 602, so that the dust can be filtered in multiple stages through multiple filter plates 604. Through the above operation, the dust in the shredder 1 can be effectively prevented from overflowing, and the surrounding environment and staff can be prevented from being affected.

[0028] See Figures 1-4It is known that an anti-clogging mechanism 7 is provided through the inner side of the filter box 603. The anti-clogging mechanism 7 includes a support shaft 701, a pulley set 702, a rotating shaft 703, and a cleaning brush 704. The rotating shaft 703 is rotatably connected to the first mounting bracket inside the filter box 603 via a bearing. The cleaning brush 704 is provided at the rear end of the rotating shaft 703. The collection box B8 is movably connected to the bottom end of the rotating shaft 703. The support shaft 701 is rotatably connected to the upright plate at the top of the filter box 603 via a bearing. The pulley set 702 is connected between the output end of the rotary motor 606 and the support shaft 701, and between the support shaft 701 and the rotating shaft 703.

[0029] See Figures 2-4 As can be seen, since the support shaft 701 and the output end of the rotary motor 606, as well as the rotary shaft 703 and the support shaft 701, are all linked through the pulley set 702, when the rotary motor 606 is working, the output end of the rotary motor 606 causes the support shaft 701, the rotary shaft 703, and the cleaning brush 704 to rotate together under the action of the pulley set 702. Thus, the dust on the filter plate 604 can be cleaned through the cleaning brush 704, which can prevent the filter plate 604 from clogging and ensure the filtration effect, making the waste crusher more convenient to use.
