Abstract

A system for de-plugging rotating ground engaging tools of an agricultural implement includes first and second ground engaging tools spaced apart from each other such that a flow gap is defined between the tools, a rotational actuator configured to rotationally drive the tools about a rotational axis, a sensor configured to capture data indicative of material accumulation within the flow gap defined between the tools, and a controller configured to determine when the tools are experiencing a plugged condition based on the data received from the sensor. Additionally, in response to the determination that the tools are experiencing the plugged condition, the controller is further configured to control an operation of the rotational actuator such that the tools are rotationally driven while such tools are disposed at a working position relative to a soil surface of a field.

First claim

The invention claimed is:

1. A system for de-plugging rotating ground engaging tools of an agricultural implement, the system comprising:
first and second ground engaging tools configured to be supported relative to a frame of an agricultural implement, the first and second ground engaging tools being spaced apart from each other such that a flow gap is defined between the first and second ground engaging tools;
a rotational actuator configured to rotationally drive the first and second ground engaging tools about a rotational axis;
a sensor configured to capture data indicative of material accumulation within the flow gap defined between the first and second ground engaging tools; and
a controller communicatively coupled to the rotational actuator and the sensor, the controller configured to:
determine when the first and second ground engaging tools are experiencing a plugged condition based on the data received from the sensor;
monitor a current ground speed of the agricultural implement as the agricultural implement is being moved across the field during the performance of an agricultural operation; and
control an operation of the rotational actuator such that the first and second ground engaging tools are rotationally driven about the rotational axis in response to the determination that the first and second ground engaging tools are experiencing the plugged condition, the controller being configured to control the operation of the rotational actuator such that the first and second ground engaging tools are rotationally driven at a rotational speed selected as a function of the current ground speed of the agricultural implement,

wherein the first and second ground engaging tools are rotationally driven by the rotational actuator while the first and second ground engaging tools are disposed at a working position relative to a soil surface of a field.

2. The system of claim 1 , wherein the first and second ground engaging tools comprise disk blades, the disk blades being ganged together via a common shaft extending axially along the rotational axis.

3. The system of claim 2 , wherein the rotational actuator is rotatably coupled to the common shaft such that the rotational actuator is configured to rotationally drive the first and second ground engaging tools by rotating the common shaft.

4. The system of claim 1 , wherein the rotational speed is selected based on a predetermined non-plugged tool speed at which it is expected that the first and second ground engaging tools will rotate due to engagement with the field while the agricultural implement is being moved across the field at the current ground speed.

5. The system of claim 1 , wherein the controller is configured to control the operation of the rotational actuator such that the first and second ground engaging tools are rotationally driven for a predetermined time period in response to the determination that the first and second ground engaging tools are experiencing the plugged condition.

6. The system of claim 1 , wherein the controller is configured to control the operation of the rotational actuator such that the first and second ground engaging tools are rotationally driven at a rotational speed that is varied over time.

7. The system of claim 1 , wherein the rotational actuator comprises one of a hydraulic motor or an electric motor.

8. The system of claim 1 , further comprising a clutch configured to selectively engage and disengage the rotational actuator relative to the first and second ground engaging tools, the controller being configured to control an operation of the clutch to engage the rotational actuator with the first and second ground engaging tools in response to the determination that the first and second ground engaging tools are experiencing the plugged condition.

9. An agricultural implement, comprising:
a frame;
a disk gang including a plurality of disk blades supported relative to the frame, the plurality of disk blades being ganged together via a common shaft for rotation about a rotational axis;
a rotational actuator coupled to the common shaft such that the rotational actuator is configured to rotationally drive the plurality of disk blades about the rotational axis;
a sensor configured to capture data indicative of material accumulation within a flow gap defined between adjacent disk blades of the plurality of disk blades; and
a controller communicatively coupled to the rotational actuator and the sensor, the controller configured to:
determine when the disk gang is experiencing a plugged condition based on the data received from the sensor;
monitor a current ground speed of the agricultural implement as the agricultural implement is being moved across the field during the performance of an agricultural operation;
control an operation of the rotational actuator such that the plurality of disk blades are rotationally driven about the rotational axis in response to the determination that the disk gang is experiencing the plugged condition, the controller being configured to control the operation of the rotational actuator such that the plurality of disk blades are rotationally driven at a rotational speed selected as a function of the current ground speed of the agricultural implement,

wherein the plurality of disk blades are rotationally driven by the rotational actuator while the plurality of disk blades are disposed at a working position relative to a soil surface of a field.

10. The agricultural implement of claim 9 , wherein the rotational speed is selected based on a predetermined non-plugged tool speed at which it is expected that the plurality of disk blades will rotate due to engagement with the field while the agricultural implement is being moved across the field at the current ground speed.

11. The agricultural implement of claim 9 , wherein the controller is configured to control the operation of the rotational actuator such that the plurality of disk blades are rotationally driven for a predetermined time period in response to the determination that the disk gang is experiencing the plugged condition.

12. The agricultural implement of claim 9 , wherein the controller is configured to control the operation of the rotational actuator such that the plurality of disk blades are rotationally driven at a rotational speed that is varied over time.

13. The agricultural implement of claim 9 , further comprising a clutch configured to selectively engage and disengage the rotational actuator relative to the common shaft, the controller being configured to control an operation of the clutch to engage the rotational actuator with the common shaft in response to the determination that the disk gang is experiencing the plugged condition.

14. A method for de-plugging rotating ground engaging tools of an agricultural implement, the agricultural implement including a frame and first and second ground engaging tools configured to be supported relative to the frame such that a flow gap is defined between the first and second ground engaging tools, the method comprising:
