Patent attributes
A particle delivery system of an agricultural row unit includes a particle belt housing configured to be disposed adjacent to a particle metering and singulation unit and a particle belt disposed within the particle belt housing. The particle belt includes a base, a plurality of flights extending from the base, a particle engagement section configured to receive a particle from the particle metering and singulation unit, and a particle exit section configured to expel the particle toward a trench in soil. The particle delivery system includes a flex system coupled to the particle belt housing proximate to the particle exit section of the particle belt, where the flex system is configured to drive each flight of the plurality of flights to temporarily flex, such that the flight drives the particle to accelerate through the particle exit section in response to straightening of the flight.
