Abstract

A particulate material leveling system includes an agitating system disposed within a storage tank for a particulate material. The agitating system includes a drive system and a shaft coupled to the drive system. Further, the drive system drives the shaft to rotate about a central axis. The agitating system also includes a wrapped wire coupled to the shaft. The wrapped wire extends around the shaft along a helical path in an axial direction and a circumferential direction, and the wrapped wire moves the particulate material in the axial direction in response to rotation of the shaft in a first direction about the central axis.

First claim

The invention claimed is:

1. A particulate material leveling system for an agricultural system comprising a storage tank for a particulate material, multiple meter rollers, multiple row units, each meter roller configured to distribute the particulate material to at least one row unit, the particular material leveling system comprising:
an agitating system disposed within the storage tank and upstream of the multiple meter rollers, the agitating system comprising:
a drive system;
a shaft coupled to the drive system, wherein the drive system is configured to drive the shaft to rotate about a central axis;
a wrapped wire, wherein the wrapped wire extends around the shaft along a helical path in an axial direction and a circumferential direction, and the wrapped wire is configured to move the particulate material in the axial direction in response to rotation of the shaft in a first direction about the central axis; and
a controller communicatively coupled to the drive system, and configured to control the drive system to rotate the shaft to provide an even distribution of the particulate material across all of the multiple meter rollers.

2. The particulate material leveling system of claim 1 , wherein the drive system is configured to be manually operated.

3. The particulate material leveling system of claim 1 , wherein the drive system comprises an electric motor.

4. The particulate material leveling system of claim 3 , wherein the controller is configured to control the electric motor to rotate the shaft a number of turns in the first direction about the central axis in response to determining that a variation between a measured profile of the particulate material and a target profile of the particulate material exceeds a threshold value.

5. The particulate material leveling system of claim 3 , wherein the controller is configured to control the electric motor to rotate the shaft in alternating directions about the central axis in response to determining that a variation between a measured profile of the particulate material and a target profile of the particulate material is below a threshold value.

6. The particulate material leveling system of claim 1 , wherein the agitating system comprises a plurality of agitating members coupled to the shaft.

7. The particulate material leveling system of claim 1 , comprising at least one mounting member configured to couple the wrapped wire to the shaft, wherein the at least one mounting member is formed at an end of the wrapped wire.

8. A particulate material leveling system comprising:
an agitating system configured to be disposed within a storage tank for a particulate material, wherein the agitating system is configured to direct the particulate material to multiple meter rollers, each meter roller configured to meter the particulate material to at least one row unit of an agricultural system, and wherein the agitating system comprising:
a drive system;
a shaft coupled to the drive system, wherein the drive system is configured to drive the shaft to rotate about a central axis;
a plurality of wrapped wires, wherein the plurality of wrapped wires extend around the shaft along a helical path in an axial direction and a circumferential direction, and the plurality of wrapped wires is configured to move the particulate material in the axial direction in response to rotation of the shaft in a first direction about the central axis; and
a controller communicatively coupled to the drive system, and configured to control the drive system to rotate the shaft to provide an even distribution of the particulate material across all of the multiple meter rollers.

9. The particulate material leveling system of claim 8 , wherein the drive system is configured to be manually operated.

10. The particulate material leveling system of claim 8 , wherein the drive system comprises an electric motor.

11. The particulate material leveling system of claim 10 , wherein the controller is configured to control the electric motor to rotate the shaft a number of turns in the first direction about the central axis in response to determining that a variation between a measured profile of the particulate material and a target profile of the particulate material exceeds a threshold value.

12. The particulate material leveling system of claim 8 , wherein at least one wrapped wire of the plurality of wrapped wires has a round cross-section.

13. The particulate material leveling system of claim 8 , wherein the agitating system comprises a plurality of agitating members coupled to the shaft and disposed axially between at least two of the plurality of wrapped wires.

14. The particulate material leveling system of claim 8 , comprising a plurality of mounting members configured to couple the plurality of wrapped wires to the shaft, wherein the plurality of mounting members are formed at respective ends of the plurality of wrapping wires.

15. A particulate material leveling system of an agricultural system, the particulate material leveling system comprising:
an agitating system configured to be disposed within a storage tank for a particulate material and upstream of multiple meter rollers, each meter roller configured to meter the particulate material to at least one row unit of the agricultural system, wherein the agitating system is configured to direct the particulate material to multiple meter rollers, the agitating system comprising:
a drive system;
a shaft coupled to a drive system, and the drive system is configured to cause the shaft to rotate about a central axis;
a plurality of wrapped wires, wherein the plurality of wrapped wires extend around the shaft along a helical path in an axial direction and a circumferential direction, a first wrapped wire of the plurality of wrapped wires is configured to move the particulate material in a first axial direction along the shaft and in response to rotation of the first wrapped wire in a first rotational direction about the central axis, and a second wrapped wire of the plurality of wrapped wires is configured to move the particulate material in a second axial direction, opposite the first axial direction, along the shaft and in response to rotation of the second wrapped wire in the first rotational direction about the central axis; and
a controller communicatively coupled to the drive system, and configured to control the drive system to rotate the shaft to provide an even distribution of the particulate material across all of the multiple meter rollers,
