Abstract: A distribution system for agricultural chemicals includes a primary auger conveyor that delivers particulates from a common hopper structure. The hopper is provided with primary and secondary particulate compartments. Primary particulate compartment discharges into a first auger conveyor. When a mixture of two particulate components is desired, the second component can be discharged from the secondary hopper compartment by operation of a second conveyor leading to the first. Liquid stored on-board the supporting vehicle can also be discharged into the main auger conveyor to wet the particulates prior to their delivery.

Abstract: A transverse air distribution system for field application of particulates, such as fertilizers, utilizes a plurality of pneumatic delivery tubes. The delivery tubes are arranged in two vertically stacked transverse layers. Air is supplied through a manifold chamber in communication with each layer of tubes. A metered amount of particulates is discharged into vertical chutes leading to the individual delivery tubes by operation of individual rotating metering augers. The number of metering auger outlets corresponds to the number of delivery tubes, assuring that identical amounts of particulate flow will be provided to each delivery tube during operation of the apparatus. A supporting metering housing and delivery tube housing are hinged to the vehicle frame to provide convenient access for repair, modification or cleaning of the metering system.
