ABSTRACT:
This invention pertains to cleaning apparatus for a conveyor belt. This cleaner employs gravitational force to apply vibratory action on the conveyor belt. A free-turning roller engages the inner surface of the returning extent of the conveyor belt at a point and position near the tail pulley. Four embodiments are shown. The first shows the motor and vibrated pulley disposed between the extents of belt. The second embodiment has the motor disposed below the return extent of belt. The third embodiment in which the belt extents are too close together to mount the motor between the belts has the motor disposed above the incomming belt. The fourth embodiment shows vibration isolators which are used to reduce any transmission of vibrations into the frame supporting the pulleys of the conveyor belt. The vibrated frame is carried in channel shaped guideways lined with a non-metallic liner so the vibrated frame is gravitationally movable in the channels.
