Abstract

Embodiments of the present disclosure include an agitating system of an agricultural system having a drive system configured to operate an agitator and a controller comprising a memory and a processor. The controller is configured to alternatingly instruct the drive system to operate the agitator in an active operation for an active time and instruct the drive system to suspend operation of the agitator for a dwell time after the active time.

First claim

The invention claimed is:

1. An agitating system of an agricultural system, comprising:
a drive system configured to operate an agitator via a motor;
a sub-hopper configured to couple to a metering system, wherein the agitator moves particulate material in the sub-hopper; and
a controller comprising a memory and a processor, wherein the controller is configured to alternatingly:
instruct the drive system to operate the agitator in an active operation for an active time;
instruct the drive system to suspend operation of the agitator for a dwell time after the active time; and
determine the dwell time based on a geometry of a seed meter of the metering system, a density of particulate material within the sub-hopper, a mass flow rate of the particulate material through the seed meter, or any combination thereof.

2. The agitating system of claim 1 , wherein the active operation comprises moving particulate material in a forward direction or moving the particulate material in a reverse direction.

3. The agitating system of claim 1 , wherein the agitator comprises a coil, and wherein instructing the drive system to operate the agitator via the motor in the active operation comprises instructing the drive system to rotate the agitator in a first rotational direction to move particulate material in a forward direction or instructing the drive system to rotate the agitator in a second rotational direction opposite the first rotational direction to move particulate material in a reverse direction opposite the forward direction.

4. The agitating system of claim 1 , wherein the agitator is configured to promote movement of particulate material through the sub-hopper into the metering system.

5. The agitating system of claim 1 , wherein the controller is configured to determine the active time based on a length of an inlet to a seed meter of the metering system, a geometry of the agitator, an operating speed of the agitator, or any combination thereof.

6. The agitating system of claim 1 , wherein the controller is configured to receive a user input and to determine the active time, the dwell time, or both, based on the user input.

7. The agitating system of claim 1 , wherein the active time and the dwell time are not equal to one another.

8. An agitating system of an agricultural system, comprising:
an agitator comprising an agitator coil;
a drive system configured to drive the agitator via a motor to rotate; and
a controller comprising a memory and a processor, wherein the controller is configured to:
instruct the drive system to drive the agitator to rotate in a forward rotational direction for a forward time;
instruct the drive system to suspend rotation of the agitator for a dwell time after the forward time;
instruct the drive system to drive the agitator to rotate in a reverse rotational direction for a reverse time after the dwell time; and
determine the dwell time based on a geometry of a seed meter of a metering system, a density of particulate material within a sub-hopper, a mass flow rate of the particulate material through the seed meter, or any combination thereof.

9. The agitating system of claim 8 , wherein the forward time and the reverse time are approximately equal to one another.

10. The agitating system of claim 8 , wherein the controller is configured to receive a user input and to determine the forward time, the reverse time, the dwell time, or any combination thereof, based on the user input.

11. The agitating system of claim 8 , wherein the controller is configured to determine the forward time, the reverse time, or both, based on a length of an inlet to a seed meter of a metering system, a geometry of the agitator, an operating speed of the agitator, or any combination thereof.

12. The agitating system of claim 8 , wherein the controller is configured to instruct the drive system to suspend rotation of the agitator via the motor for a second dwell time after the reverse time.
