ABSTRACT:
A conveyor for granular material includes an elongated hollow channel covered by a suitable cover and having a hollow interior along which the granular material is to be conveyed. A rotary screw extends along the hollow interior of the channel for conveying the granular material therein, this rotary screw including an elongated shaft and a screw carried thereby. Between the opposed ends of the elongated shaft there is situated within the channel at least on bearing which supports the shaft for rotary movement, and a transverse wall extends across the interior of the channel and is supported thereby, this transverse wall carrying the bearing, so that the bearing together with the transverse wall carrying the same block the travel of the granular material longitudinally along the interior of the channel. A bypass structure cooperates with the channel at the region of the transverse wall and bearing carried thereby for providing for the granular material a path of flow bypassing the transverse wall and bearing, so that in this way the shaft of the rotary screw can be effectively supported for rotary movement while at the same time the material can be effectively conveyed.
