The rotating installation shaft 3 drives the dispersion part 4 to operate, so that the cloth on the conveyor is dispersed during conveying to avoid excessive cloth entering at one time, so that the cloth accumulates during shredding, and also avoids excessive cloth entering to cause cloth scattering.

[0030] Further, referring to Figure 4 、 Figure 7 and Figure 8 , the dispersion part 4 includes an eccentric wheel 10 fixed on the installation shaft 3, a dispersion plate 11 rotatably installed on the feeding bin 2 and matched with the eccentric wheel 10, a horizontal plate 12 fixed on the feeding bin 2, and a spring sheet 1 3 fixed on the horizontal plate 12 and abutting against the dispersion plate 11.

[0031] In the scheme, the driving part 9 provides power to rotate the installation shaft 3, thereby driving the eccentric wheel 10 to rotate and cyclically extruding the dispersion plate 11, and then cooperating with the extrusion reset of the spring sheet 1 3, so that the dispersion plate 11 continuously shakes to shake the cloth conveyed on the conveyor and avoid excessive cloth entering the cloth shredder 1 at one time.

[0036] In the scheme, the liquid supply device is used to supply liquid to the dust falling cylinder 20, and the trigger part 21 is used to spray the liquid to wet the outside of the cloth, so that the cloth is not easy to be broken into particles when it is crushed and torn later.
