ABSTRACT:
The present invention is directed to a folding mechanism for the discharge spout system (12) of a pneumatic conveyor (10). The folding mechanism includes a hinge mechanism (55) having an axis (66) which is skewed with respect to a plane perpendicular to the alignment axis (26) of lower and upper tubes (20, 22). Such a hinge mechanism (55) allows the upper portion of upper tube (22) to pass the lower portion of lower tube (20) while upper tube (22) is pivoting from an operational configuration to a transit configuration. An hydraulic cylinder (68) powers the pivotal movement of upper tube (22). An over-center locking mechanism (84) latches lower and upper tubes (20, 22) in the operational configuration.
