Abstract

An agricultural airplane loading device having a wheeled frame on which is mounted a hopper provided with a lower portion forming a discharge opening. Arranged below the hopper for receiving material from the discharge opening of the hopper is an auger conveyor which elevates the material received from the hopper at an angle permitting the material to be discharged into a reservoir of an airplane without contacting the aircraft. A gate arrangement controls flow of material from the hopper to the conveyor, while a pulley affixed to the auger for rotating same is provided with a mass disposed eccentrically of the auger for vibrating the hopper when the conveyor is in operation and preventing bridging and tunnelling of material in the hopper.
