ABSTRACT:
A hopper cylindrical about a vertical axis has an agitator with blades rotating near the bottom of the hopper, not only to agitate insulation but also to move it through a hopper outlet opening into an airlock having a horizontal shaft and radially spaced blades. The vertical shaft for the hopper agitator and the horizontal airlock shaft are aligned so that one may be driven from the other, as by miter gears. A motor and reduction gearing may drive the airlock shaft, through a chain and sprocket connection, or the motor and reduction gearing may drive the hopper agitator shaft through a coupling. The blades of the airlock rotor may be individually removable through the airlock inlet, as in order to replace flexible wipers. Each airlock blade may have a flange at an obtuse angle such as 150.degree. which is bolted to one side of the multisided shaft by a series of cap bolts. Preferably, the number of blades is even, so that the shaft has a corresponding number of sides and tapped holes for the cap bolts that extend completely through the shaft, to the opposite side and cap bolts for opposed blades enter opposite ends of the holes. For other blades, the holes are spaced longitudinally, so that no holes will intersect. The bottom of the hopper may be a relatively thick, circular plate to which the equipment in a circular, base enclosure may be attached. Other features are also disclosed.
