Rotatory unloading mechanism

The utility model discloses a rotatory unloading mechanism, its technical scheme main points are rotatory unloading mechanism, including rolling disc and control rolling disc pivoted power portion, circumference is provided with the through -hole on the rolling disc, the through -hole below is provided with the on -off mechanism that the control through -hole was opened and close. The utility model has the advantages that through being provided with the on -off mechanism that can control the through -hole and open and close in rolling disc below, avoided using the condition of the backup pad separation powder that the slope set up among the prior art, what on -off mechanism can the direct control through -hole opens and close, and the powder on the rolling disc is direct because self gravity falls perpendicularly simultaneously, has avoided the powder to block up the condition of discharge opening.
