Particle delivery system of an agricultural row unit

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

• a particle belt having a particle acceleration 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;
• a first wheel engaged with the particle belt at a first location and at a first end of the first wheel;
• a second wheel engaged with the particle belt at a second location and at a first end of the second wheel, wherein the particle acceleration section extends between the first location and the second location, and a substantially no-slip condition exists between the first wheel and the particle belt at the first location and between the second wheel and the particle belt at the second location;
• and
• a drive mechanism coupled to a second end of the first wheel and a second end of the second wheel, wherein the drive mechanism is configured to be driven by the first wheel rotating at a first rotational speed, and the drive mechanism is configured to drive rotation of the second wheel at a second rotational speed faster than and proportional to the first rotational speed 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 wheel engaged with the particle belt at a first location;
• a second wheel engaged with the particle belt at a second location, wherein the particle acceleration section extends between the first location and the second location, a substantially no-slip condition exists between the first wheel and the particle belt at the first location and between the second wheel and the particle belt at the second location, and the second wheel is configured to rotate faster than the first wheel 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 at the particle exit section, such that a difference between the particle exit speed and a target particle exit speed is less than a threshold value.
