Patent attributes
A particle delivery system of an agricultural row unit includes an inner particle belt having a base and a plurality of flights extending outwardly from the base. Each pair of opposing flights of the plurality of flights is configured to receive a particle from a particle metering and singulation unit, and each flight is configured to rotate relative to the base. The particle delivery system includes an outer particle belt having a plurality of apertures, where each flight of the plurality of flights extends through a respective aperture of the plurality of apertures, and the outer particle belt is configured to drive rotation of the flight relative to the base as the inner particle belt and the outer particle belt rotate, such that rotation of the flight relative to the base accelerates the particle toward a trench in soil.
