Abstract
A harvester apparatus having adjust suppression system provided for suppressing grain dust during crop harvesting operations wherein the harvester apparatus has a vehicle body with a harvesting mechanism for harvesting the crops and supplying the crops to an accumulator bin on the vehicle body. A discharge apparatus is provided to empty the accumulator bin and includes an elongated housing extending from the accumulator bin and terminating in a discharge opening. An elongated auger is rotatably mounted to the vehicle body about a longitudinal axis in an interior of the tubular housing. The auger transports the crops from the accumulator bin to the discharge opening during rotation. A nozzle mounted to the elongated housing has a spray opening located in the tubular passageway. Structure is provided for supplying a dust suppressing fluid to the spray opening of the nozzle for application to the crops being transported through the elongated housing by the auger.
