A drive mechanism (DM) is connected to ends of the conveyor tubes (28), for reciprocating the conveyor tubes (28). The drive mechanism (DM) functions to move the conveyor tubes (28) in one direction, for moving material that is on and between the conveyor tubes (28), and for retracting the conveyor tubes (28) in the opposite direction.
