Agricultural dispensing mechanisms

摘要

Mechanism for dispensing seed or fertilizer for agricultural row crop implements such as seed drills and precision planters. A resilient rotatable roller cooperates with a flat vertical glass dispensing plate to dispense seed or fertilizer from a hopper through a nip between the plate and the roller. A slightly raised narrow slow rate band on the roller cooperates sealingly with a pair of removable confinement flanges so that small seeds such as kale can be confined to the slow rate band and dispensed much more slowly than if the whole width of the roller were used.
