A circular shaft is horizontally arranged above the discharging end, and a rotating motor is arranged on the material frame for driving the circular shaft to rotate. The circular shaft is fixed with a plurality of scattering pieces arranged side by side along the axial direction of the circular shaft. The scattering piece is in the structure of a circular saw blade, and comprises a central hole through which the circular shaft passes.
