Abstract
A novel seed metering device which accommodates a large diversity of seed types and sizes by utilizing a rotating two crevice helical pattern in which individual seeds are channeled around two opposing rotors and dispensed singularly or volumetrically based on desired outcome. The two opposing rotors, each with a half set of creviced helical patterns, are adjustable to open and close in order to accommodate seed size and type. When the rotors are adjusted all the way in, the primary crevice is closed and the secondary crevice remains open for the smaller seed sizes to pass through and evenly dispense. As the rotors are adjusted out away from each other, incremental increases can be achieved in order to find the ideal crevice width to accommodate the seed diameter for singular or even disbursement.
Claims14
A seed metering device, the device comprising:
- a. a rotational driving member,
- b. two opposing rotors, said rotors comprising an outer circumference and an inner circumference,
- c. wherein at least one opposing rotor has a half set of creviced and cut patterns, and
- d. wherein when the cut pattern is proximately mated closed, a creviced slot opening remains, following a trajectorially elliptical pattern around the outer circumference of the rotor, as to proximately create an even width slot width throughout the entire trajectorial circumference.
A seed metering device, the device comprising:
- a. a rotational driving member,
- b. two opposing rotors,
- c. wherein at least one opposing rotor has a half set of curved helical creviced and curved helical cut patterns,
- d. wherein when the cut pattern is proximately mated closed, a creviced slot opening remains, following a trajectorially curved helical elliptical pattern around the outer circumference of the rotor, as to proximately create an even width slot width throughout the entire trajectorial circumference.
A seed metering device, comprising:
- a. a rotational driving member,
- b. two opposing rotors,
- c. wherein each opposing rotor has a half set of cut patterns with a cut angle between about 20 and about 60 degrees to central axis,
- d. wherein the cut pattern is helically curved around cut angle, whereby creating a consistent discharge angle along the moving seed drop location as the opposing rotors rotate.
