Variable geometry meter roller
An agricultural metering device with a variable geometry meter roller is provided. The agricultural metering device includes a meter roller having a plurality of flutes. An aggregate cross sectional area of the flutes increases along a longitudinal axis of the meter roller.
1. An agricultural metering device, comprising:
a meter roller having a plurality of flutes, a first longitudinal end, and a second longitudinal end, the meter roller configured to meter product within the agricultural metering device, wherein an aggregate cross sectional area of the flutes increases along a longitudinal axis of the meter roller between the first longitudinal end and the second longitudinal end of the meter roller.
2. The agricultural metering device of claim 1 , wherein the aggregate cross sectional area increases continuously along the longitudinal axis of the meter roller.
3. The agricultural metering device of claim 1 , wherein a depth of each flute increases along the longitudinal axis of the meter roller.
4. The agricultural metering device of claim 1 , wherein a width of each flute increases along the longitudinal axis of the meter roller.
5. The agricultural metering device of claim 1 , wherein a depth and a width of each flute increase along the longitudinal axis of the meter roller.
6. The agricultural metering device of claim 1 , wherein the meter roller comprises a plurality of ridges, and each flute forms a curved recess between adjacent ridges.
7. The agricultural metering device of claim 1 , wherein each flute twists about the longitudinal axis as the flute extends between the first and second longitudinal ends.
8. The agricultural metering device of claim 1 , comprising a meter roller cover configured to selectively cover a portion of the meter roller to adjust product flow rate.
