Abstract

A system includes an agricultural metering system a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The first meter roller segment includes a first profile, the second meter roller includes a second profile, and the first profile is different from the second profile. The system also has a dividing ring axially positioned between the first meter roller segment and the second meter roller segment.

First claim

The invention claimed is:

1. An agricultural metering system, comprising:
a meter roller configured to meter product to a product distribution system via rotation of the meter roller, wherein the meter roller comprises:
a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses;
a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses, wherein the first meter roller segment has a first profile, the second meter roller segment has a second profile, and the first profile is different from the second profile; and

a slide configured to selectively block at least a portion of the product from flowing to the meter roller in response to sliding the slide along a longitudinal axis of the meter roller.

2. The agricultural metering system of claim 1 , wherein the slide is configured to move in a first direction toward a closed position that substantially blocks the product from engaging the meter roller, and in a second direction toward an open position that facilitates flow of the product into at least one meter roller segment of the first and second meter roller segments.

3. The agricultural metering system of claim 2 , wherein the slide has a hole configured to unblock the first meter roller segment while the slide is in the open position.

4. The agricultural metering system of claim 1 , wherein the slide is configured to substantially match a shape of an outer surface of the meter roller such that a distance between the slide and the outer surface is less than an average radius of the product.

5. The agricultural meter system of claim 1 , wherein the slide comprises a flat slide configured to translate over the meter roller to block flow of the product to the first meter roller segment, the second meter roller segment, or any combination thereof.

6. The agricultural metering system of claim 1 , wherein the first profile is finer than the second profile.

7. An agricultural metering system, comprising:
a meter roller configured to meter product to a product distribution system via rotation of the meter roller, wherein the meter roller comprises:
a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses;
a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses, wherein the first meter roller segment has a first profile, the second meter roller segment has a second profile, and the first profile is different from the second profile; and

a slide configured to selectively block at least a portion of the product from flowing to the meter roller in response to sliding the slide along a longitudinal axis of the meter roller, wherein the slide is curved to substantially match a shape of an outer surface of the meter roller.

8. The agricultural metering system of claim 7 , wherein the slide is configured to move in a first direction toward a closed position that substantially blocks the product from engaging the meter roller, and in a second direction toward an open position that facilitates flow of the product into at least one meter roller segment of the first and second meter roller segments.

9. The agricultural metering system of claim 7 , wherein the slide is configured to substantially match the shape of the outer surface of the meter roller such that a distance between the slide and the outer surface is less than an average radius of the product.

10. The agricultural metering system of claim 7 , wherein the slide comprises a groove panel configured to engage with a groove wheel, and the slide is configured to translate in response to rotation of the groove wheel.

11. The agricultural metering system of claim 7 , wherein the first profile is finer than the second profile.

12. An agricultural metering system, comprising:
a meter roller configured to meter product to a product distribution system via rotation of the meter roller, wherein the meter roller comprises:
a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses;
a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses, wherein the first meter roller segment has a first profile, the second meter roller segment has a second profile, and the first profile is different from the second profile; and

a slide configured to selectively block at least a portion of the product from flowing to the meter roller in response to sliding the slide along a longitudinal axis of the meter roller, wherein the slide comprises a groove panel configured to engage with a groove wheel, and the slide is configured to translate in response to rotation of the groove wheel.

13. The agricultural metering system of claim 12 , wherein the slide is configured to move in a first direction toward a closed position that substantially blocks the product from engaging the meter roller, and in a second direction toward an open position that facilitates flow of the product into at least one meter roller segment of the first and second meter roller segments.

14. The agricultural metering system of claim 13 , wherein the slide has a hole configured to unblock the first meter roller segment while the slide is in the open position.

15. The agricultural metering system of claim 12 , wherein the slide is configured to substantially match a shape of an outer surface of the meter roller such that a distance between the slide and the outer surface is less than an average radius of the product.

16. The agricultural meter system of claim 12 , wherein the slide comprises a flat slide configured to translate over the meter roller to block flow of the product to the first meter roller segment, the second meter roller segment, or any combination thereof.

17. The agricultural metering system of claim 12 , wherein the first profile is finer than the second profile.
