Abstract

A method for reducing material accumulation relative to ground-engaging tools of a tillage implement includes receiving measurement signals from at least one accumulation sensor mounted to the tillage implement during a tillage operation. The measurement signals include a three-dimensional (3D) representation of an environment containing material accumulation relative to a plurality ground-engaging tools. The method also includes estimating an amount of material accumulation relative to the plurality of ground-engaging tools based on the 3D representation. Further, the method includes comparing the amount of material accumulation to an accumulation threshold. The material accumulation threshold is indicative of a given degree of material accumulation relative to the plurality of ground-engaging tools. Thus, based on the comparison between the amount of material accumulation and the accumulation threshold, the method includes controlling an operation of at least one component of the tillage implement to execute a control action for reducing the amount of the material accumulation.

First claim

What is claimed is:

1. A method for reducing material accumulation relative to a plurality of ground-engaging tools of a tillage implement, the method comprising:
receiving, with a computing device, measurement signals from at least one accumulation sensor mounted to the tillage implement during a tillage operation, the measurement signals comprising a three-dimensional (3D) representation of an environment containing material accumulation relative to one or more of the ground-engaging tools of the tillage implement, the material accumulation comprising an accumulation of field materials relative to the one or more of the ground-engaging tools;
estimating, with the computing device, an amount of material accumulation relative to the plurality of ground-engaging tools based on the 3D representation;
comparing, with the computing device, the amount of material accumulation relative to the plurality of ground-engaging tools to first and second predetermined accumulation thresholds, the first predetermined accumulation threshold differing from the second predetermined accumulation threshold such that the first and second predetermined accumulation thresholds are indicative of respective first and second degrees of material accumulation relative to the plurality of ground-engaging tools, the second degree of material accumulation corresponding to a greater amount of material accumulation relative to the first degree of material accumulation; and
controlling, with the computing device, an operation of at least one component of the tillage implement to sequentially execute first and second control actions for reducing the amount of the material accumulation relative to the plurality of ground-engaging tools, with such control of the at least one component comprising:
executing the first control action when the amount of material accumulation relative to the plurality of ground-engaging tools reaches or passes the first predetermined accumulation threshold;
determining that the amount of material accumulation relative to the plurality of ground-engaging tools has reached or passed the second predetermined accumulation threshold following execution of the first control action; and
subsequently executing the second control action to reduce the amount of material accumulation relative to the plurality of ground-engaging tools,

wherein the first control action differs from the second control action.

2. The method of claim 1 , wherein the measurement signals from the at least one accumulation sensor further comprise information indicative of at least one of material accumulation flow past the plurality of ground-engaging tools, material accumulation type, density of the material accumulation, or moisture content of the material accumulation.

3. The method of claim 1 , wherein the at least one accumulation sensor comprises at least one of a three-dimensional (3D) imaging sensor, a Light Detection and Imaging (LiDAR) sensor, an ultrasound sensor, a smart sensor, or combinations thereof.

4. The method of claim 1 , further comprising:
mounting the at least one accumulation sensor to a front end of the tillage implement;
directing the at least one accumulation sensor towards one or more of the plurality of ground-engaging tools; and
monitoring the amount of material accumulation in an area in front of one or more of the ground-engaging tools.

5. The method of claim 1 , wherein one of the first control action or the second control action comprises adjusting a penetration depth of one or more of the plurality of ground-engaging tools for a predetermined period of time.

6. The method of claim 1 , wherein one of the first control action or the second control action comprises raising the plurality of ground-engaging tools out of the ground.

7. The method of claim 1 , wherein executing the first control action comprises temporarily reducing a penetration depth of one or more of the plurality of ground-engaging tools for a predetermined period of time, and wherein executing the second control action comprises raising the plurality of ground-engaging tools out of the ground.

8. The method of claim 1 , further comprising generating, with the computing device, a notification indicative of the amount of material accumulation exceeding at least one of the first accumulation threshold or the second accumulation threshold.

9. The method of claim 1 , wherein the implement includes a frame, a first actuator configured to raise one or more of the plurality of ground-engaging tools to a raised position above the ground, and a second actuator configured to actuate the one or more ground-engaging tools while the one or more of the plurality of ground-engaging tools are located at the raised position, and wherein:
executing the first control action comprises controlling the operation of the first actuator to reduce a penetration depth of the one or more ground-engaging tools; and
executing the second control action comprises:
controlling the operation of the first actuator to raise the one or more ground-engaging tools to the raised position above the ground; and
controlling the operation of the second actuator to actuate the one or more ground-engaging tools while the one or more ground-engaging tools are located at the raised position to reduce the amount of material accumulation relative to the one or more ground-engaging tools.

10. The method of claim 9 , wherein the first actuator comprises a hydraulic cylinder and the second actuator comprises one of a vibrational actuator or a rotational actuator.

11. The method of claim 9 , wherein controlling the operation of the second actuator comprises controlling the operation of the second actuator to vibrate the one or more of the plurality of ground-engaging tools while the one or more ground-engaging tools are located at the raised position.

12. The method of claim 9 , wherein the one or more ground-engaging tools comprises one or more rotary ground-engaging tools, wherein controlling the operation of the second actuator comprises controlling the operation of the second actuator to rotate the one or more rotary ground-engaging tools in reverse relative to a rotational direction of the one or more rotary ground-engaging tools when the one or more rotary ground-engaging tools are engaging the ground.

13. A system for reducing material accumulation relative to ground-engaging tools when performing a tillage operation, the system comprising:
an implement including a frame and a plurality of ground-engaging tools supported on the frame;
an ultrasound sensor mounted to the implement; and
a controller including a processor and associated memory, the memory including instructions that, when implemented by the processor, configure the controller to perform one or more operations, the one or more operations comprising:
receiving ultrasound data from the ultrasound sensor during the tillage operation, the ultrasound data providing a three-dimensional (3D) representation of an environment extending upwardly from a surface of the ground that contains material accumulation relative to at least one of the plurality ground-engaging tools, the material accumulation comprising an accumulation of field materials on or above the surface of the ground relative to the one or more of the ground-engaging tools;
