ABSTRACT:
The main storage hopper of an aerial crop dusting apparatus incorporated in aircraft is equipped with a suction pipe which extends from the outlet to the lowest depths of the hopper to insure that all the insecticide stored therein is dispensed. The suction pipe has a constant cross-sectional area throughout its length to insure constant fluid flow. The pipe attaches to the outlet by a connector which has a free bevelled edge to contact a bevelled edge of the pipe. A nut is positioned over a flange on the pipe and has threads which connect with cooperating threads on the connector to force the bevelled edges into tight communication.
