Abstract

A method for reducing material accumulation relative to ground-engaging tools of a tillage implement may include monitoring, with a computing device, an accumulation parameter as a tillage operation is being performed, wherein the accumulation parameter provides an indication of material accumulation relative to a plurality of ground-engaging tools of the tillage implement. The method may also include comparing, with the computing device, the accumulation parameter to a material accumulation threshold, wherein the material accumulation threshold is indicative of a given degree of material accumulation relative to the plurality ground-engaging tools. In addition, based on the comparison between the accumulation parameter and the material accumulation threshold, the method may include controlling, with the computing device, an operation of at least one component of the tillage implement to execute a control action for reducing an amount of the material accumulation relative to the plurality of ground-engaging tools.

First claim

What is claimed is:

1. A method for reducing material accumulation relative to ground-engaging tools of a tillage implement, the method comprising:
monitoring, with a computing device, an accumulation parameter as a tillage operation is being performed, the accumulation parameter providing an indication of material accumulation relative to a plurality ground-engaging tools of the tillage implement;
comparing, with the computing device, the accumulation parameter to a material accumulation threshold, the material accumulation threshold being indicative of a given degree of material accumulation relative to the plurality of ground-engaging tools; and
based on the comparison between the accumulation parameter and the material accumulation threshold, controlling, with the computing device, an operation of at least one component of the tillage implement to execute a control action for reducing an amount of the material accumulation relative to the plurality of ground-engaging tools, wherein the control action comprises:
raising the plurality of ground-engaging tools out of the ground; and
subsequently actuating the plurality of ground-engaging tools,

wherein actuating the plurality of ground-engaging tools comprises at least one of rotating the plurality of ground-engaging tools in a direction that is opposite a rotational direction of the plurality of ground-engaging tools during the performance of the tillage operation, or vibrating the plurality of ground-engaging tools.

2. The method of claim 1 , wherein the accumulation parameter is associated with at least one of a speed of material adjacent to the plurality of ground-engaging tools, a proximity of material to a fixed location on the tillage implement, or a rotational speed of one or more of the plurality of ground-engaging tools.

3. The method of claim 2 , wherein the accumulation parameter is associated with a comparison of a ground speed of the tillage implement and the speed of the material.

4. The method of claim 1 , wherein monitoring the accumulation parameter comprises receiving, with the computing device, measurement signals from at least one accumulation sensor mounted to the tillage implement.

5. The method of claim 1 , wherein comparing the accumulation parameter to the material accumulation threshold comprises comparing the accumulation parameter to a first predetermined accumulation threshold and a second predetermined accumulation threshold, the second predetermined accumulation threshold differing from the first predetermined accumulation threshold and being indicative of a greater degree of material accumulation relative to the plurality of ground-engaging elements.

6. The method of claim 1 , wherein the control action further comprises temporarily reducing a penetration depth of the plurality of ground-engaging elements for a predetermined period of time prior to raising the plurality of ground-engaging tools out of the ground.

7. The method of claim 1 , wherein the plurality of ground-engaging tools comprise a plurality of rotary tools of the implement.

an implement including a frame and a plurality of ground-engaging tools supported on the frame;
a controller including a processor and associated memory, the memory including instructions that, when implemented by the processor, configure the controller to:
monitor an accumulation parameter as the tillage operation is being performed, the accumulation parameter providing an indication of material accumulation relative to the plurality of ground-engaging tools;

based on the comparison between the accumulation parameter and the material accumulation threshold, control an operation of at least one component of the tillage implement to execute a control action for reducing an amount of the material accumulation relative to the plurality of ground-engaging tools, the control action comprising raising the plurality of ground-engaging tools out of the ground and subsequently actuating the plurality of ground-engaging tools,

wherein actuating the plurality of ground-engaging tools comprises at least one of rotating the plurality of ground-engaging tools in a direction that is opposite a rotational direction of the plurality of ground-engaging tools during the performance of the tillage operation, or vibrating the plurality of ground-engaging tools.

9. The system of claim 8 , wherein the accumulation parameter is associated with at least one of a speed of material adjacent to the plurality of ground-engaging tools, a proximity of material to a fixed location on the tillage implement, or a rotational speed of one or more of the plurality of ground-engaging tools.

10. The system of claim 8 , further comprising at least one accumulation sensor supported by the frame, the at least one accumulation parameter configured to transmit measurement signals to the controller associated with the accumulation parameter.

11. The system of claim 10 , wherein the at least one accumulation sensor comprises at least one of an optical sensor, a proximity sensor, or a rotational speed sensor.

12. The method of claim 8 , wherein the controller is configured to compare the accumulation parameter to a first predetermined accumulation threshold and a second predetermined accumulation threshold, the second predetermined accumulation threshold differing from the first predetermined accumulation threshold and being indicative of a greater degree of material accumulation relative to the plurality of ground-engaging elements.

13. A method for reducing material accumulation relative to ground-engaging tools of a tillage equipment, the method comprising:
monitoring, with a computing device, an accumulation parameter as a tillage operation is being performed, the accumulation parameter providing an indication of material accumulation relative to a plurality ground-engaging tools of the tillage implement, the accumulation parameter being monitored by determining at least one of a speed of material flowing relative to the plurality of ground-engaging tools or a proximity of the material to a fixed location on the tillage implement;
