Abstract

An agitator for an agricultural system includes a shaft configured to rotate about a rotational axis during operation of the agricultural system, and an extension coupled to the shaft. The extension includes a hoop and a tine extending from the hoop, and the tine extends acutely relative to the rotational axis of the shaft.

First claim

The invention claimed is:

1. An agitator for an agricultural system, comprising:
a shaft configured to rotate about a rotational axis during operation of the agricultural system; and
an extension coupled to the shaft, wherein the extension includes a hoop and a tine extending from the hoop, the tine extends acutely relative to the rotational axis of the shaft, the hoop is configured to overlap an inlet of a metering system of the agricultural system relative to the rotational axis, and the tine is configured to be offset from the inlet of the metering system relative to the rotational axis.

2. The agitator of claim 1 , comprising a sub-hopper and the metering system, wherein the metering system is configured to couple to the sub-hopper, and the inlet is configured to receive particulate material.

3. The agitator of claim 2 , wherein the shaft, the extension, or both, are disposed within the sub-hopper.

4. The agitator of claim 1 , wherein the hoop is aligned with the inlet relative to the rotational axis.

5. The agitator of claim 1 , comprising a driver configured to cyclically rotate the shaft in a first rotational direction about the rotational axis and in a second rotational direction, opposite the first rotational direction, about the rotational axis.

6. The agitator of claim 1 , wherein the hoop and the tine of the extension have a circular cross-section or a rectangular cross-section.

7. The agitator of claim 1 , wherein an entirety of the extension is positioned on a lateral side of the shaft, or the shaft extends through the extension.

8. The agitator of claim 1 , wherein the tine extends along the shaft and forms an acute angle with the shaft.

9. An agitating system for an agricultural system, comprising:
a sub-hopper configured to couple to a metering system having a plurality of inlets;
a shaft disposed within the sub-hopper and configured to rotate about a rotational axis during operation of the agricultural system; and
a plurality of extensions coupled to the shaft, wherein each extension of the plurality of extensions includes a hoop and a tine integrally formed with the hoop, each extension of the plurality of extensions is positioned along the shaft such that each hoop overlaps an inlet of the plurality of inlets relative to the rotational axis, and each tine extends acutely relative to the rotational axis and is offset from the inlet relative to the rotational axis.

10. The agitating system of claim 9 , wherein a respective hoop and a respective tine of each extension of the plurality of extensions form a U-shape, a J-shape, an L-shape, or any combination thereof.

11. The agitating system of claim 9 , wherein a first extension of the plurality of extensions comprises the tine and an additional tine that extend from the hoop.

12. The agitating system of claim 11 , wherein a second extension of the plurality of extensions is positioned adjacent to the first extension of the plurality of extensions, and the tine of the second extension extends away from the first extension.

13. The agitating system of claim 12 , wherein the second extension is positioned on a first side of the first extension relative to the rotational axis, the tine of the second extension extends away from the first extension in a first direction relative to the rotational axis, a third extension of the plurality of extensions is positioned adjacent to the first extension on a second side of the first extension, opposite the first side, relative to the rotational axis, and the tine of the third extension extends away from the first extension in a second direction, opposite the first direction, relative to the rotational axis.

14. The agitating system of claim 13 , wherein a first arc length of the hoop of the first extension is smaller than a second arc length of the hoop of the second extension and a third arc length of the hoop of the third extension.

15. The agitating system of claim 9 , wherein each extension of the plurality of extensions is coupled to the shaft via a welded connection, a fastener, an interference fit, or any combination thereof.

16. The agitating system of claim 9 , wherein each extension of the plurality of extensions is integrally formed with the shaft.

17. An agitator for an agricultural system, comprising:
a shaft configured to rotate about a rotational axis during operation of the agricultural system;
an extension coupled to the shaft, wherein the extension includes a hoop and a tine extending from the hoop, and the tine extends acutely relative to the rotational axis of the shaft;
a sub-hopper;
a metering system configured to couple to the sub-hopper, wherein the metering system includes an inlet configured to receive particulate material; and
a driver configured to cyclically rotate the shaft in a first rotational direction about the rotational axis and in a second rotational direction, opposite the first rotational direction, about the rotational axis, wherein the hoop overlaps the inlet of the metering system relative to the rotational axis, and the tine is offset from the inlet relative to the rotational axis.
