[0013] 2. The utility model improves the sound insulation effect by setting the outer shell and the inner shell, and the double-layer hollow shell structure reduces the noise pollution when the rotary discharger is working, which is conducive to the implementation of the policy of green and safe production.

[0014] 3.
