A dry inoculant dispenser includes a hopper with dry inoculant therein, and a conveyor for carrying dry product to a vertical drop tube. The drop tube is connected to a dispenser tube that will direct the inoculant to the forage material. A flow of air is created in the dispenser tube to carry inoculant therethrough, and a vacuum is created in the drop tube such that dry inoculant within the drop tube is sucked into the dispenser tube and dispensed from the distal end thereof.

What is claimed is: 1. A dry product dispenser, comprising: an enclosed hopper for retaining a dry product to be dispensed; a selectively operable feeder assembly having an upstream end communicating with the hopper and a downstream end extending therefrom, for carrying dry product from said hopper
What is claimed is: 1. A dry product dispenser, comprising: an enclosed hopper for retaining a dry product to be dispensed; a selectively operable feeder assembly having an upstream end communicating with the hopper and a downstream end extending therefrom, for carrying dry product from said hopper; a vertical drop tube having an upper end in communication with the downstream end of the feeder assembly, and a lower open end; said feeder assembly including an auger operably disposed within an elongated pipe to convey dry product from the hopper to the drop tube; said feeder assembly being electrically connected to a control box with controls for activating the feeder assembly to operate and adjust the speed of the feeder assembly; a dispenser tube connected to the lower end of the drop tube and extending therefrom to a distal end, for directing dry product dispensed therethrough; and means for creating an air flow through the dispenser tube from the drop tube to the distal end and for creating a vacuum within the drop tube, whereby dry product within the drop tube is sucked into the dispenser tube and dispensed from the distal end thereof; said means for creating an air flow and for creating a vacuum includes: a venturi interposed between the drop tube and dispenser tube, the venturi including: a central bore with upstream and downstream ends; a short constricted diameter portion generally centered between the ends; the bore ends tapering from the constricted portion to a larger diameter at the ends; and an inlet port oriented perpendicular to the bore and communicating with the constricted portion; the lower end of the drop tube connected to and communicating with the venturi inlet port; the downstream end of the venturi connected to and communicating with the dispenser tube; and a source of air under pressure connected to the upstream end of the venturi, to supply air flow through the venturi. 2. The dispenser of claim 1, wherein said source of air pressure includes a centrifugal blower with an output connected to the venturi upstream end. 3. The dispenser of claim 2, wherein said blower is electrically connected to a control box with controls for activating the blower to operate and adjust the speed of the blower. 4. A dry product dispenser, comprising: an enclosed hopper for retaining a dry product to be dispensed; a selectively operable feeder assembly having an upstream end communicating with the hopper and a downstream end extending therefrom, for carrying dry product from said hopper; a vertical drop tube having an upper end in communication with the downstream end of the feeder assembly, and a lower open end; a dispenser tube connected to the lower end of the drop tube and extending therefrom to a distal end, for directing dry product dispensed therethrough; and means for creating an air flow through the dispenser tube from the drop tube to the distal end and for creating a vacuum within the drop tube, whereby dry product within the drop tube is sucked into the dispenser tube and dispensed from the distal end thereof; said means for creating an air flow and for creating a vacuum including: a venturi interposed between the drop tube and dispenser tube, the venturi including: a central bore with upstream and downstream ends; a short constricted diameter portion generally centered between the ends; the bore ends tapering from the constricted portion to a larger diameter at the ends; and an inlet port oriented perpendicular to the bore and communicating with the constricted portion; the lower end of the drop tube connected to and communicating with the venturi inlet port; the downstream end of the venturi connected to and communicating with the dispenser tube; and a source of air under pressure connected to the upstream end of the venturi, to supply air flow through the venturi. 5. The dispenser of claim 4, wherein said source of air pressure includes a centrifugal blower with an output connected to the venturi upstream end. 6. The dispenser of claim 5, wherein said blower is electrically connected to a control box with controls for activating the blower to operate and adjust the speed of the blower. 7. In combination: a harvester, including: a cutting head for cutting a crop to create conditioned forage material; a cab for an operator to operate the harvester; and a spout for dispensing conditioned forage material from the harvester; and a dry inoculant dispensing system mounted on the harvester, for dispensing dry inoculant at a very low inclusion rate uniformly over the forage material, comprising: an enclosed hopper for retaining dry inoculant to be dispensed; a selectively operable feeder assembly having an upstream end communicating with the hopper and a downstream end extending therefrom, for carrying dry inoculant from said hopper; a vertical drop tube having an upper end in communication with the downstream end of the feeder assembly, and a lower open end; a dispenser tube having a first end connected to the lower end of the drop tube and a distal end extending therefrom to a location positioned over and directed at the forage material, for directing dry inoculant dispensed therethrough; and means for creating an air flow through the dispenser tube from the first end to the distal end and for creating a vacuum within the drop tube, whereby dry product within the drop tube is sucked into the dispenser tube and dispensed from the distal end thereof; said means for creating an air flow and for creating a vacuum including: a venturi interposed between the drop tube and dispenser tube, the venturi including: a central bore with upstream and downstream ends; a short constricted diameter portion generally centered between the ends; the bore ends tapering from the constricted portion to a larger diameter at the ends; and an inlet port oriented perpendicular to the bore and communicating with the constricted portion; the lower end of the drop tube connected to and communicating with the venturi inlet port; the downstream end of the venturi connected to and communicating with the dispenser tube; and a source of air under pressure connected to the upstream end of the venturi, to supply air flow through the venturi.
