Abstract

In one aspect, a system for monitoring operational parameters associated with a tillage implement may include a first sensor configured to detect data indicative of a first distance between an implement frame forward of a ground engaging tool and a soil surface prior to engagement of the soil by the tool. The system may also include a second sensor configured to detect data indicative of a second distance between the frame aft of the tool and the soil surface following engagement of the soil by the tool. A controller of the system may be configured to determine a soil density change caused by engagement of the soil by the tool based on the first and second distances. Furthermore, the controller may be configured to determine a penetration depth of the tool based at least in part on the determined change in the soil density.

First claim

What is claimed is:

1. A system for monitoring operational parameters associated with a tillage implement during the performance of a field operation, the system comprising:
a tillage implement frame including a forward end and an aft end;
a plurality of ground engaging tools coupled to the frame and configured to engage the soil to perform a tillage operation as the tillage implement is moved across a field in a direction of travel;
a first sensor coupled to the frame at a location forward of a first ground engaging tool of the plurality of ground engaging tools relative to the direction of travel, the first sensor configured to detect data indicative of a first distance between the frame at the location forward of the first ground engaging tool and a soil surface of the field prior to engagement of the soil by the first ground engaging tool;
a second sensor coupled to the frame at a location aft of the first ground engaging tool relative to the direction of travel, the second sensor configured to detect data indicative of a second distance between the frame at the location aft of the first ground engaging tool and the soil surface of the field following engagement of the soil by the first ground engaging tool; and
a controller communicatively coupled to the first and second sensors, the controller being configured to:
determine the first and second distances based on data received from the first and second sensors, respectively;
determine a change in a soil density of the soil caused by engagement of the soil by the first ground engaging tool based on the determined first and second distances as the implement is being moved across the field; and
determine a penetration depth of the first ground engaging tool within the soil based at least in part on the determined change in the soil density.

2. The system of claim 1 , wherein each of the first and second sensors corresponds to at least one of a radio detection and ranging (RADAR) sensor, a light detection and ranging (LIDAR) sensor, or an ultrasonic sensor.

3. The system of claim 1 , wherein the controller is further configured to determine the penetration depth of the first ground engaging tool based on at least one of soil moisture, soil type, or residue coverage.

4. The system of claim 1 , wherein the controller is further configured to initiate a control action when the determined penetration depth has fallen outside of a predetermined penetration depth range.

5. The system of claim 4 , wherein the control action is associated with notifying an operator of the tillage implement that the determined penetration depth has fallen outside of the predetermined penetration depth range.

6. The system of claim 4 , wherein the control action is associated with reducing a ground speed of the tillage implement.

7. The system of claim 4 , wherein the control action is associated with adjusting the penetration depth of the first ground engaging tool.

8. The system of claim 7 , wherein the first ground engaging tool is pivotably coupled to the frame, the system further including an actuator coupled between the frame and the first ground engaging tool, the controller being configured to control an operation of the actuator such that the actuator adjusts the position of the first ground engaging tool relative to the frame to adjust the penetration depth of the first ground engaging tool.

9. The system of claim 1 , wherein the first ground engaging tool comprises a shank.

10. The system of claim 1 , wherein the controller is further configured to generate an operator notification when the determined change in the soil density falls outside of a predetermined range.

11. A tillage implement, comprising:
a frame extending along a lateral direction between a first end and a second end, the frame including a forward end and an aft end;
a plurality of ground engaging tools coupled to the frame and configured to engage the soil to perform a tillage operation as the tillage implement is moved across a field in a direction of travel, at least two ground engaging tools of the plurality of ground engaging tools being spaced apart along the lateral direction;
a first sensor coupled to the frame at a location forward of a first ground engaging tool of the plurality of ground engaging tools relative to the direction of travel, the first sensor configured to detect data indicative of a first distance between the frame at the location forward of the first ground engaging tool and a soil surface of the field prior to engagement of the soil by the first ground engaging tool;
a second sensor coupled to the frame at a location aft of the first ground engaging tool relative to the direction of travel, the second sensor configured to detect data indicative of a second distance between the frame at the location aft of the first ground engaging tool and the soil surface of the field following engagement of the soil by the first ground engaging tool; and
a controller communicatively coupled to the first and second sensors, the controller being configured to:
determine the first and second distances based on the data received from the first and second sensors, respectively;
determine a change in a soil density of the soil caused by engagement of the soil by the first ground engaging tool based on the determined first and second distances as the implement is being moved across the field, and
determine a penetration depth of the first ground engaging tool within the soil based at least in part on the determined change in the soil density.

12. A method for monitoring operational parameters associated with a tillage implement during the performance of a field operation, the tillage implement including a frame and a plurality of ground engaging tools coupled to the frame, each ground engaging tool being configured to engage the soil as the tillage implement is moved across a field, the method comprising:
determining, with a computing device, a first distance between the frame at a location forward of a first ground engaging tool of the plurality of ground engaging tools relative to a direction of travel and a soil surface of the field prior to engagement of the soil by the first ground engaging tool based on data received from a first sensor;
determining, with the computing device, a second distance between the frame at a location aft of the first ground engaging tool relative to the direction of travel and the soil surface of the field following engagement of the soil by the first ground engaging tool based on data received from a second sensor;
determining, with the computing device, a change in a soil density of the soil caused by engagement of the soil by the first ground engaging tool based on the determined first and second distances as the implement is being moved across the field;
determining, with the computing device, a penetration depth of the first ground engaging tool through the soil based at least in part on the determined change in the soil density; and
initiating, with the computing device, a control action to adjust an operational parameter of the tillage implement when the determined penetration depth has fallen outside of a predetermined penetration depth range.

13. The method of claim 12 , wherein each of the first and second sensors corresponds to at least one of a radio detection and ranging (RADAR) sensor, a light detection and ranging (LIDAR) sensor, or an ultrasonic sensor.

14. The method of claim 12 , further comprising:
determining, with the computing device, the penetration depth of the first ground engaging tool based on the first and second distances and at least one of soil moisture
