Prevent hopper of material adhesion

The utility model relates to a prevent hopper of material adhesion. Including planking (1) and inner panel (2) of setting in planking (1), form between planking (1) and inner panel (2) intermediate layer (3), planking (1) and inner panel (2) forms through the flexible coupling and connects, set up attached to vibrator (4) on the inner panel (2) in intermediate layer (3). The utility model discloses setting the hopper structural style of inner panel, planking to, and forming the intermediate layer between the inner panel, planking, planking, the inner panel form through the flexible coupling forms to be connected, and when the vibrator is opened, the inner panel receives the vibration like this, and the planking is owing to the buffering of flexible coupling, and the relative inner panel of its vibration range is less, consequently the utility model discloses a planking no. 1 can play the support to the inner panel, and two can reduce partly noise because of the oscillation generation, improve operator's opera
