US Patent 11553639 Particle delivery system of an agricultural row unit

A particle delivery system of an agricultural row unit includes a particle metering and singulation unit configured to meter a plurality of particles from a particle storage area and a particle belt disposed a selected distance apart from the particle metering and singulation unit. The particle belt is configured to receive the plurality of particles from the particle metering and singulation unit. The selected distance between the particle metering and singulation unit and the particle belt enables the plurality of particles to accelerate under an influence of gravity to a particle speed at the particle belt within a target percentage of a belt speed of the particle belt.
