Abstract

A particulate material agitation and leveling system includes a controller having a memory and a processor. The processor is configured to receive a sensor signal indicative of a measured weight distribution of a particulate material within a storage tank of an agricultural system, determine whether a determined variation between the measured weight distribution and a target weight distribution is greater than a threshold variation, and control an agitator to decrease the determined variation in response to determining that the determined variation is greater than the threshold variation.

First claim

The invention claimed is:

1. A particulate material agitation and leveling system, comprising:
a controller comprising a memory and a processor, wherein the controller is configured to:
receive at least one sensor signal indicative of a measured weight distribution of a particulate material within a storage tank of an agricultural system;
determine whether a determined variation between the measured weight distribution and a target weight distribution is greater than a threshold variation; and
control an agitator to decrease the determined variation in response to determining that the determined variation is greater than the threshold variation, wherein the agitator is configured to be positioned between the storage tank and a metering system of the agricultural system along a vertical axis of the agricultural system.

2. The particulate material agitation and leveling system of claim 1 , wherein the at least one sensor signal indicative of the measured weight distribution comprises a plurality of signals indicative of measured weights, wherein the controller is configured to determine the measured weight distribution based on the plurality of signals indicative of the measured weights and respective locations of a plurality of sensors configured to output the plurality of signals indicative of the measured weights.

3. The particulate material agitation and leveling system of claim 2 , comprising the plurality of sensors configured to output the plurality of signals indicative of the measured weights of the particulate material within the storage tank.

4. The particulate material agitation and leveling system of claim 2 , wherein each sensor of the plurality of sensors is configured to measure a weight of the particulate material at a location along the storage tank.

5. The particulate material agitation and leveling system of claim 4 , wherein the location along the storage tank comprises a side of the storage tank, a corner of the storage tank, or a combination thereof.

6. The particulate material agitation and leveling system of claim 1 , wherein the controller is configured to determine the target weight distribution based on a user input, an initial measured weight distribution, a type of the particulate material, or a combination thereof.

7. The particulate material agitation and leveling system of claim 1 , comprising a drive system coupled to the agitator, wherein the controller is configured to output a control signal to the drive system to control the agitator.

8. A particulate material agitation and leveling system, comprising:
a controller comprising a memory and a processor, wherein the controller is configured to:
receive at least one sensor signal indicative of a measured weight of a particulate material within a storage tank of an agricultural system;
select an operating mode of an agitator from an agitation mode and a leveling mode based on the measured weight, wherein the agitator is configured to be positioned between the storage tank and a metering system of the agricultural system along a vertical axis of the agricultural system; and
operate the agitator based on the operating mode.

9. The particulate material agitation and leveling system of claim 8 , wherein the controller is configured to:
receive at least one sensor signal indicative of an initial measured weight of the particulate material within the storage tank; and
determine a threshold weight based on the initial measured weight.

10. The particulate material agitation and leveling system of claim 9 , wherein selecting the operating mode is based on the measured weight and the threshold weight.

11. The particulate material agitation and leveling system of claim 10 , wherein the controller is configured to select the agitation mode in response to the measured weight being greater than or equal to the threshold weight.

12. The particulate material agitation and leveling system of claim 10 , wherein the controller is configured to select the leveling mode in response to the measured weight being less than the threshold weight.

13. The particulate material agitation and leveling system of claim 8 , comprising the agitator and a drive system coupled to and configured to rotate the agitator.

14. The particulate material agitation and leveling system of claim 13 , wherein the controller, while the agitation mode is selected, is configured to operate the agitator by instructing the drive system to rotate the agitator in a first direction and then in a second direction, opposite of the first direction, to agitate the particulate material.

15. The particulate material agitation and leveling system of claim 13 , wherein the controller, while the leveling mode is selected, is configured to operate the agitator by instructing the drive system to rotate the agitator in a first direction and then in a second direction, opposite of the first direction, to level the particulate material.

16. The particulate material agitation and leveling system of claim 8 , comprising at least one sensor communicatively coupled to the controller and configured to output the at least one sensor signal indicative of the measured weight of the particulate material within the storage tank.

17. A particulate material agitation and leveling system, comprising:
an agitator configured to be positioned between a storage tank of an agricultural system and a metering system of the agricultural system along a vertical axis of the agricultural system;
a drive system coupled to and configured to rotate the agitator;
a sensor configured to output a sensor signal indicative of a measured weight of particulate material within a storage tank configured to feed the particulate material through the agitator; and
a controller communicatively coupled to the sensor, wherein the controller comprises a memory and a processor, wherein the controller is configured to:
receive the sensor signal indicative of the measured weight of the particulate material;
select an operating mode of the agitator from an agitation mode and a leveling mode based on the measured weight; and
operate the drive system based on the operating mode.

18. The particulate material agitation and leveling system of claim 17 , wherein the controller is configured to:
receive a sensor signal indicative of an initial measured weight of the particulate material within the storage tank; and
determine a threshold weight based on the initial measured weight, wherein selecting the operating mode is based on the measured weight and the threshold weight.

19. The particulate material agitation and leveling system of claim 17 , wherein the controller is configured to:
determine a measured weight distribution based on the sensor signal indicative of the measured weight of the particulate material;
determine whether a determined variation between the measured weight distribution and a target weight distribution is greater than a threshold variation; and
select the leveling mode in response to determining that the determined variation is greater than the threshold variation.

20. The particulate material agitation and leveling system of claim 19 , wherein the controller is configured to:
select a direction of rotation of the agitator based on the measured weight distribution; and
operate the drive system based on the selected direction of rotation of the agitator.
