Abstract

In one aspect, a system for detecting plugging of an agricultural implement may include a disc rotatably coupled to a frame member, with the disc configured to rotate relative to soil within a field as the implement is moved across the field. The system may also include a disc scraper coupled to the frame member, with the disc scraper configured to remove the soil from the disc as the disc rotates relative to the soil. Furthermore, the system may include a sensor configured to detect a parameter indicative of an acceleration of the disc scraper relative to frame member. Additionally, a controller of the system may be configured to monitor the acceleration of the disc scraper relative to the frame member based on data received from the sensor moreover. The controller may be further configured to determine when the disc is plugged based on the monitored acceleration.

First claim

The invention claimed is:

1. A system for detecting plugging of an agricultural implement, the system comprising:
a frame member;
a disc rotatably coupled to the frame member, the disc configured to rotate relative to soil within a field as the agricultural implement is moved across the field;
a disc scraper coupled to the frame member, the disc scraper configured to remove the soil from the disc as the disc rotates relative to the soil;
a sensor configured to detect a parameter indicative of an acceleration of the disc scraper relative to frame member; and
a controller communicatively coupled to the sensor, the controller configured to monitor the acceleration of the disc scraper relative to the frame member based on data received from the sensor, the controller further configured to determine when the disc is plugged based on the monitored acceleration.

2. The system of claim 1 , wherein the controller is further configured to:
compare the monitored acceleration to a predetermined minimum acceleration value; and
determine that the disc is plugged when the monitored acceleration falls below the predetermined minimum acceleration value.

3. The system of claim 1 , wherein the controller is further configured to determine that the disc is plugged when the monitored acceleration is zero.

4. The system of claim 1 , wherein the controller is further configured to initiate a control action associated with de-plugging the disc when it is determined that the disc is plugged.

5. The system of claim 4 , wherein the control action comprises notifying an operator of the agricultural implement that the disc is plugged.

6. The system of claim 4 , wherein the control action comprises adjusting an operating parameter of the agricultural implement.

7. The system of claim 6 , wherein the operating parameter comprises a ground speed of the agricultural implement.

8. The system of claim 6 , wherein the operating parameter comprises at least one of a down pressure applied to or a penetration depth of the disc.

9. The system of claim 1 , wherein the controller is further configured to:
initiate a first control action when the monitored acceleration falls below a first predetermined minimum acceleration value; and
initiate a second control action when the monitored acceleration falls below a second predetermined minimum acceleration value, the second predetermined minimum acceleration value being less than the first predetermined minimum acceleration value.

10. The system of claim 9 , wherein the first control action comprises adjusting an operating parameter of the agricultural implement and the second control action comprises halting the operation of the agricultural implement.

11. A method for detecting plugging of an agricultural implement, the agricultural implement including a disc configured to rotate relative to soil within a field as the agricultural implement is moved across the field, the agricultural implement further including a disc scraper configured to remove the soil from the disc as the disc rotates relative to the soil, the method comprising:
monitoring, with a computing device, an acceleration of the disc scraper relative to a frame member of the agricultural implement;
determining, with the computing device, when the disc is plugged based on the monitored acceleration; and
initiating, with the computing device, a control action associated with de-plugging the disc when it is determined that the disc is plugged.

12. The method of claim 11 , wherein determining when the disc is plugged comprises:
comparing, with the computing device, the monitored acceleration to a predetermined minimum acceleration value; and
determining, with the computing device, that the disc is plugged when the monitored acceleration falls below the predetermined minimum acceleration value.

13. The method of claim 11 , wherein determining when the disc is plugged comprises determining, with the computing device, that the disc is plugged when the monitored acceleration is zero.

14. The method of claim 11 , wherein the control action comprises notifying an operator of the agricultural implement that the disc is plugged.

15. The method of claim 11 , wherein the control action comprises adjusting an operating parameter of the agricultural implement.

16. The method of claim 15 , wherein the operating parameter comprises a ground speed of the agricultural implement.

17. The method of claim 15 , wherein the operating parameter comprises at least one of a down pressure applied to or a penetration depth of the disc.

18. The method of claim 11 , wherein initiating the control action comprises:
initiating, with the computing device, a first control action when the monitored acceleration falls below a first predetermined minimum acceleration value; and
initiating, with the computing device, a second control action when the monitored acceleration falls below a second predetermined minimum acceleration value, the second predetermined minimum acceleration value being less than the first predetermined minimum acceleration value.

19. The method of claim 18 , wherein the first control action comprises adjusting an operating parameter of the agricultural implement and the second control action comprises halting the operation of the agricultural implement.
