Particle delivery system of an agricultural row unit

A particle delivery system of an agricultural row unit, comprising:

• a particle metering and singulation unit configured to meter a plurality of particles from a particle storage area;
• a particle belt having a particle acceleration section, wherein the particle belt is configured to receive the plurality of particles from the particle metering and singulation unit, to accelerate the plurality of particles at the particle acceleration section, and to expel the plurality of particles toward a trench in soil;
• a first hub assembly engaged with the particle belt at a first location;
• and
• a second hub assembly engaged with the particle belt at a second location, wherein the particle acceleration section is disposed generally at the first location, a substantially no-slip condition exists between the first hub assembly and the particle belt at the first location and between the second hub assembly and the particle belt at the second location, and the first hub assembly and the second hub assembly are configured to stretch the particle belt at the particle acceleration section to accelerate the particle at the particle acceleration section.

A particle delivery system of an agricultural row unit, comprising:

• a particle belt having a particle acceleration section and a particle exit section, wherein the particle belt is configured to receive a particle from a particle metering and singulation unit, to accelerate the particle at the particle acceleration section, and to expel the particle toward a trench in soil at the particle exit section;
• a first hub assembly engaged with the particle belt at a first location;
• a second hub assembly engaged with the particle belt at a second location, wherein the particle acceleration section is disposed generally at the first location, a substantially no-slip condition exists between the first hub assembly and the particle belt at the first location and between the second hub assembly and the particle belt at the second location, and the first hub assembly and the second hub assembly are configured to stretch the particle belt at the particle acceleration section to accelerate the particle at the particle acceleration section;
• and
• a controller comprising a memory and a processor, wherein the controller is configured to:
• receive an input signal indicative of a particle exit speed of the particle at the particle exit section of the particle belt;
• and
• output an output signal indicative of instructions to adjust a belt speed of the particle belt, such that a difference between the particle exit speed and a target particle exit speed is less than a threshold value.
