Abstract

A system for monitoring wear of shank attachment members of an agricultural implement includes a shank extending between a proximal end and a distal end, the proximal end configured to be pivotally coupled to a portion of the agricultural implement, a shank attachment member coupled to the distal end of the shank, a non-contact sensor positioned remote to the shank attachment member, the non-contact sensor configured to detect a parameter indicative of wear of the shank attachment member, and a controller communicatively coupled to the non-contact sensor. The controller is configured to determine a status of the wear of the shank attachment member based on sensor data received from the non-contact sensor while the shank attachment member is above ground.

First claim

What is claimed is:

1. A wear monitoring system for shank attachment members of an agricultural implement, the wear monitoring system comprising:
a shank extending between a proximal end and a distal end, the proximal end configured to be pivotally coupled to a portion of the agricultural implement;
a shank attachment member coupled to the distal end of the shank;
a non-contact sensor positioned remote to the shank attachment member, the non-contact sensor configured to detect a parameter indicative of wear of the shank attachment member, the non-contact sensor comprising a ground-penetrating radar sensor; and
a controller communicatively coupled to the non-contact sensor, the controller configured to determine a status of the wear of the shank attachment member based on sensor data received from the non-contact sensor, the sensor data including the parameter indicative of the wear of the shank attachment member,
wherein the non-contact sensor is configured to generate the sensor data when the shank attachment member is positioned at least partially below a ground surface.

2. The wear monitoring system of claim 1 , wherein the non-contact sensor is configured to detect a distance between the non-contact sensor and an outer surface of the shank attachment member, the distance being indicative of the wear of the shank attachment member.

3. The wear monitoring system of claim 1 , wherein the shank attachment member includes a body defining a tip end, the non-contact sensor being configured to detect a distance between the non-contact sensor and an outer surface of the shank attachment member adjacent to its tip end.

4. The wear monitoring system of claim 1 , further comprising a user interface in communication with the controller, the controller being configured to indicate the status of the wear of the shank attachment member to an operator of the agricultural implement via the user interface.

5. The wear monitoring system of claim 1 , wherein the controller is configured to adjust an operation of the agricultural implement based at least in part on the determined status of the wear of the shank attachment member.

6. The wear monitoring system of claim 1 , wherein the non-contact sensor is configured to be coupled to a frame of the agricultural implement, the non-contact sensor having a field of view directed towards the shank attachment member.

7. The wear monitoring system of claim 1 , wherein the shank attachment member comprises a tillage point.

8. An agricultural implement, comprising:
a frame configured to be actuated relative to a ground surface between a raised position and a lowered position;
a shank extending between a proximal end and a distal end, the proximal end being pivotally coupled to the frame;
a shank attachment member coupled to the distal end of the shank;
a non-contact sensor coupled to the frame, the non-contact sensor configured to detect a parameter indicative of wear of the shank attachment member, the non-contact sensor comprising a ground-penetrating radar sensor; and
a controller communicatively coupled to the non-contact sensor, the controller configured to determine a status of the wear of the shank attachment member based on sensor data received from the non-contact sensor, the sensor data including the parameter indicative of the wear of the shank attachment member,
wherein the non-contact sensor is configured to generate the sensor data when the shank attachment member is positioned at least partially below the ground surface.

9. The agricultural implement of claim 8 , wherein the non-contact sensor is configured to detect a distance between the non-contact sensor and an outer surface of the shank attachment member, the distance being indicative of the wear of the shank attachment member.

10. The agricultural implement of claim 8 , wherein the shank attachment member includes a body defining a tip end, the non-contact sensor being configured to detect a distance between the non-contact sensor and an outer surface of the shank attachment member adjacent to its tip end.

11. The agricultural implement of claim 8 , wherein the controller is configured to indicate the status of the wear of the shank attachment member to an operator of the agricultural implement via a user interface communicatively coupled to the controller.

12. The agricultural implement of claim 8 , wherein the controller is configured to adjust an operation of the agricultural implement based at least in part on the determined status of the wear of the shank attachment member.

13. The agricultural implement of claim 8 , wherein the non-contact sensor is coupled to the frame such that the non-contact sensor has a field of view directed towards the shank attachment member.

14. The agricultural implement of claim 8 , wherein the shank attachment member comprises a tillage point.

15. A method for monitoring wear of a shank attachment member of an agricultural implement, the agricultural implement including a frame configured to be actuated relative to ground surface between a raised position and a lowered position, a shank extending between a proximal end and a distal end, the proximal end being pivotally coupled to the frame, the agricultural implement further including a shank attachment member coupled to the distal end of the shank, the method comprising:
receiving, with a computing device, an input indicative of the wear of the shank attachment member from a non-contact sensor supported relative to the frame,
comparing, with the computing device, the input with a predetermined wear threshold for the shank attachment member, and
determining, with the computing device, a status of the wear of the shank attachment member based on the comparison of the input with the predetermined wear threshold,
wherein the non-contact sensor comprises a ground-penetrating radar sensor, the non-contact sensor being able to generate the input indicative of the wear of the shank attachment member when the shank attachment member is positioned at least partially below the ground surface.

16. The method of claim 15 , further comprising indicating, with the computing device, to an operator of the implement that the shank attachment member needs to be replaced based on the determined status of the wear.
