US Patent 11523556 Particle delivery system of an agricultural row unit

A particle delivery system of an agricultural row unit includes a first particle belt configured to receive a particle from a particle metering and singulation unit, a second particle belt configured to receive the particle from the first particle belt and to expel the particle to a trench in soil, and a particle transfer assembly configured to facilitate transfer of the particle from the first particle belt to the second particle belt. The first particle belt is configured to accelerate the particle to a target particle transfer speed, and the second particle belt is configured to accelerate the particle to a target particle exit speed greater than the target particle transfer speed.
