ABSTRACT:
Readily attachable and detachable coupling apparatus for coupling the drive shaft of a modular plastic screw conveyor with a power source is substantially concealed and protected by the modular plastic screw conveyor. Plastic screw conveyor modules define a non-circular axial aperture suitable for sliding over a matching or cooperating non-circular full length drive shaft. The drive shaft itself also includes an axial non-circular cross-section recess at one end for receiving a cooperating journal plug. The journal plug is secured in the drive shaft by a retainer which expands radially when compressed, and such that rotation of the journal plug causes rotation of the drive shaft which in turn causes rotation of the plastic screw conveyor.
