The present disclosure generally relates to agricultural implements and, more particularly, to a system and method for controlling the operation of an agricultural implement.
It is well known that, to attain the best agricultural performance from a field, a farmer must cultivate the soil, typically through a tillage operation. Modern farmers perform tillage operations by pulling an agricultural implement, such as a tillage implement, behind an agricultural work vehicle, such as a tractor. For example, tillage implements generally include ground-engaging tillage tools, such as shanks, disk blades, and/or the like, supported on its frame. Each ground-engaging tool, in turn, is configured to be moved relative to the soil within the field as the tillage implement travels across the field. Such movement of the ground-engaging tools loosens and/or otherwise agitates the soil to prepare the field for subsequent planting operations.
As the tillage implement travels across the field, the implement may encounter varying field conditions. For example, the implement may encounter soil clods of various sizes that may require additional tilling to achieve a desired soil surface finish. In this respect, systems for controlling the operation of an agricultural implement based on the soil clods present within a field have been developed. While such systems work well, further improvements are needed.
Accordingly, an improved system and method for controlling the operation of an agricultural implement would be welcomed in the technology.
Aspects and advantages of the technology will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the technology.
In one aspect, the present subject matter is directed to a system for controlling the operation of an agricultural implement. The system includes a leveling disk gang assembly including a plurality of leveling disk blades configured to rotate relative to a surface of a field. Additionally, the system includes an imaging device configured to generate data indicative of sizes of soil clods forward or aft of the plurality of leveling disk blades relative to a direction of travel of an agricultural implement. Furthermore, the system includes an actuator configured to adjust a position of the leveling disk gang assembly within a plane defined by a longitudinal direction extending parallel to the direction of travel and a lateral direction perpendicular to the longitudinal direction. Moreover, the system includes a computing system communicatively coupled to the imaging device.

Furthermore, the method includes controlling, with the computing system, an operation of an actuator of the agricultural implement to adjust a position of the leveling disk gang assembly within a plane defined by a longitudinal direction extending parallel to the direction of travel and a lateral direction perpendicular to the longitudinal direction based on the determined sizes of the soil clods.

The agricultural implement includes a frame and a plurality of ground-engaging shanks mounted to the frame and configured to engage the soil of a field as the agricultural implement travels across the field. Additionally, the agricultural implement includes a leveling disk gang assembly mounted to the frame and positioned aft of the plurality of ground-engaging shanks in a longitudinal direction extending parallel to a direction of travel of the agricultural implement. The leveling disk gang assembly includes a plurality of leveling disk blades configured to rotate relative to a surface of the field. Furthermore, the agricultural implement includes an imaging device configured to generate data indicative of sizes of soil clods forward or aft of the plurality of leveling disk blades relative to the direction of travel of the agricultural implement. Moreover, the agricultural implement includes an actuator configured to adjust a position of the leveling disk gang assembly within a plane defined by the longitudinal direction and a lateral direction perpendicular to the longitudinal direction. Additionally, the agricultural implement includes a computing system communicatively coupled to the imaging device. The computing system is configured to determine the sizes of the soil clods based on the data generated by the imaging device. Furthermore, the computing system is configured to control the operation of the actuator to adjust the position of the leveling disk gang assembly based on the determined sizes of the soil clods.
These and other features, aspects and advantages of the present technology will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the technology and, together with the description, serve to explain the principles of the technology.
A full and enabling disclosure of the present technology, including the best mode thereof, directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended figures, in which:
Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present technology.
Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield still a further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
In general, the present subject matter is directed to a system and a method for controlling the operation of an agricultural implement, such as a tillage implement. As will be described below, the agricultural implement includes a frame and a plurality of ground-engaging shanks mounted to the frame and configured to engage the soil of a field as the implement travels across the field. Additionally, the implement includes one or more leveling disk gang assemblies positioned aft of the ground-engaging shanks. Each leveling disk gang assembly, in turn, includes a plurality of leveling disk blades ganged together (e.g., along a shaft) and configured to rotate relative to the surface of the field. Additionally, the implement includes one or more actuators configured to adjust the position(s) of the leveling disk gang assembly(ies) such that, for example, an angle defined between the leveling disk gang assembly(ies) and a centerline of the implement is increased or decreased.
Furthermore, a computing system of the disclosed system is configured to control the operation of the actuator(s) to adjust the position(s) of the leveling disk gang assembly(ies) based on the sizes of the soil clods present within the field across which the implement is traveling. More specifically, the computing system is configured to receive data from one or more imaging devices supported on the implement or an associated agricultural vehicle. Such data is, in turn, indicative of the sizes of the soil clods present within an imaged portion of the field forward or aft of the leveling disk blades. As such, the computing system may determine the sizes of the soil clods based on the data received from the imaging device(s). Thereafter, the computing system may control the operation of the actuator(s) to adjust the position(s) of the leveling disk gang assembly(ies) based on the determined sizes of the soil clods.
Controlling the operation of the actuator(s) to adjust the position(s) of the leveling disk gang assembly(ies) positioned aft of the plurality of ground-engaging shanks of an agricultural implement based on soil clod size improves the operation of the implement. More specifically, the ground-engaging shanks of an implement generate soil clods upon penetration of the field surface. Some soil clods may require additional tilling to achieve a desired soil surface finish not achievable with current implement configurations. The disclosed system and method can automatically determine the sizes of the soil clods and control the operation of the actuator(s) to adjust the position(s) of the leveling disk gang assembly(ies) based on the size of the soil clods. As such, because the disclosed system can adjust the position(s) of the leveling disk gang assembly(ies) based on clod size, and thus adjust the leveling disk blade orientation, the implement is better suited to break up larger soil clods, thereby eliminating the need for additional tillage.
Referring now to drawings,

Similarly, in other embodiments, the agricultural implement 12 may be configured as any other suitable agricultural implement configured to be towed by an agricultural vehicle.
As shown in
Additionally, the implement 12 may generally include a carriage frame assembly 30 configured to be towed by the vehicle 10 via a pull hitch or tow bar 32 in the travel direction 14 of the vehicle/implement 10/12.

Specifically, the harrow blades 50 are spaced apart from each other along the length of the corresponding harrow gang 48 and configured to engage or rotate relative to the soil within the field as the implement 12 travels across the field in the travel direction 14. In addition, the various harrow gangs 48 of harrow blades 50 may be oriented at an angle relative to the travel direction 14 of the implement 12 to promote more effective tilling of the soil.
Additionally, the carriage frame 30 supports a plurality of ground-engaging shanks 46. In such an embodiment, the shanks 46 are configured to till or otherwise engage the soil as the implement 12 is towed across the field. Additionally, the plurality of ground-engaging shanks 46 may be supported by the carriage frame 30 aft of the harrow gangs 48 relative to the direction of travel 14. During operations, the shanks 46 may generate soil clods of various sizes as the shanks 46 penetrate the soil.

The imaging devices(s) 102 is configured to generate data indicative of sizes of soil clods present within a portion of the field forward or aft of the plurality of leveling disk blades 84 relative to the direction of travel 14 of the implement 12. Such data may subsequently be used to control the operation of the actuator(s) 42 to adjust the position of the leveling disk gang assembly(ies) 82 of the implement 12.
In general, the imaging device(s) 102 may correspond to any suitable imaging device(s) configured to generate data indicative of the sizes of the soil clods. In several embodiments, the imaging device(s) 102 may be configured as a light detection and ranging (LiDAR) sensor(s). For example, the LiDAR sensor(s) may emit a light pulse and/or a light beam and receive reflections of the emitted light pulse and/or light beam.

In general, the computing system 210 may comprise any suitable processor-based device known in the art, such as a given controller or computing device or any suitable combination of controllers or computing devices. Thus, in several embodiments, the computing system 210 may include one or more processor(s) 212 and associated memory device(s) 214 configured to perform a variety of computer-implemented functions. As used herein, the term “processor” refers not only to integrated circuits referred to in the art as being included in a computer, but also refers to a controller, a microcontroller, a microcomputer, a programmable logic controller (PLC), an application specific integrated circuit, and other programmable circuits. Additionally, the memory device(s) 214 of the computing system 210 may generally comprise memory element(s) including, but not limited to, a computer readable medium (e.g., random access memory (RAM)), a computer readable non-volatile medium (e.g., a flash memory), a floppy disc, a compact disc-read only memory (CD-ROM), a magneto-optical disc (MOD), a digital versatile disc (DVD), and/or other suitable memory elements. Such memory device(s) 214 may generally be configured to store suitable computer-readable instructions that, when implemented by the processor(s) 212, configure the computing system 210 to perform various computer-implemented functions, such as one or more aspects of the methods and algorithms that will be described herein. In addition, the computing system 210 may also include various other suitable components, such as a communications circuit or module, one or more input/output channels, a data/control bus and/or the like.
It should be appreciated that the computing system 210 may correspond to an existing computing system(s) of the implement 12 and/or the agricultural vehicle 10, itself, or the computing system 210 may correspond to a separate processing device. For instance, in one embodiment, the computing system 210 may form all or part of a separate plug-in module that may be installed in association with the implement 12 and/or the agricultural vehicle 10 to allow for the disclosed systems to be implemented without requiring additional software to be uploaded onto existing control devices of the implement 12 and/or the agricultural vehicle 10.
Furthermore, it should also be appreciated that the functions of the computing system 210 may be performed by a single processor-based device or may be distributed across any number of processor-based devices, in which instance such devices may be considered to form part of the computing system 210. For instance, the functions of the computing system 210 may be distributed across multiple application-specific controllers or computing devices, such as a navigation controller, an engine computing controller, a transmission controller, an implement controller and/or the like.
In addition, the system 200 may also include a user interface 220. More specifically, the user interface 220 may be configured to provide feedback, such as feedback associated with the determined sizes of the soil clods, to the operator. As such, the user interface 220 may include one or more feedback devices (not shown), such as display screens, speakers, warning lights, and/or the like, which are configured to provide feedback from the computing system 210 to the operator. As such, the user interface 220 may, in turn, be communicatively coupled to the computing system 210 via the communicative link 202 to permit the feedback to be transmitted from the computing system 210 to the user interface 220. Furthermore, some embodiments of the user interface 220 may include one or more input devices, such as touchscreens, keypads, touchpads, knobs, buttons, sliders, switches, mice, microphones, and/or the like, which are configured to receive inputs from the operator.

Additionally, at (304), the control logic 300 includes determining the sizes of the soil clods based on the received image data. In this respect, in several embodiments, the computing system 210 may be configured to analyze the image data received at (302) to determine the sizes of the soil clods. For example, the computing system 212 may access a look-up table, equations, and/or the like stored within its memory device(s) 214 that correlates the image data received at (302) to the corresponding sizes of the soil clods. As will be described below, the determined sizes of the soil clods will be used to control an operation of the actuator(s) 42 to adjust the position(s) of the leveling disk gang assembly(ies) 82 accordingly.
Furthermore, as shown in
Moreover, at (308), the control logic 300 includes determining a quantity of the soil clods that exceed the predetermined size range. In this respect, in several embodiments, the computing system 210 may be configured to determine the quantity of the soil clods having sizes determined at (304) that exceed the predetermined size range.
Additionally, at (310), the control logic 300 includes comparing the determined quantity of soil clods to a predetermined quantity range. As mentioned above, during agricultural operations, the implement 12 may fail to break up soil clods exceeding the predetermined size range to provide a selected field surface finish, especially when the quantity of soil clods that exceed the predetermined size range exceeds the predetermined quantity range, without adjusting the position(s) of the leveling disk gang assembly(ies) 82. As such, in several embodiments, the computing system 210 may be configured to compare the quantity of soil clods determined at (308) to the predetermined quantity range. The predetermined quantity range may be a maximum quantity range in which the implement 12 would still provide a selected field surface finish without adjusting the angle 52. When the determined quantity of soil clods exceeds a maximum value of the predetermined quantity range, the control logic 300 proceeds to (312). When the determined quantity of soil clods falls below a minimum value of the predetermined quantity range or is within the predetermined quantity range, the control logic 300 returns to (302).
Furthermore, as shown in
In certain instances, the implement 12 may be better suited to break up the soil clods to provide a better field surface finish. For example, the angle 52 defined between the leveling disk gang assembly(ies) 82 and the centerline 120 of the implement may be increased when the determined quantity of the soil clods that exceed the predetermined size threshold range exceeds the predetermined quantity range. As such, the computing system 210 may be configured to control the operation of the actuator(s) 42 to adjust the position(s) of the leveling disk gang assembly(ies) 82 such that the angle 52 is increased.
In other instances, the implement 12 may be better suited to decrease the drag load applied to the vehicle 10, increase the fuel efficiency of the vehicle 10, and/or the like. For example, the angle 52 may be decreased when the determined quantity of the soil clods falls below the predetermined quantity range. As such, the computing system 210 may be configured to control the operation of the actuator(s) 42 to adjust the position(s) of the leveling disk gang assembly(ies) 82 such that the angle 52 is decreased. Upon completion of (312), the control logic 300 returns to (302).
In some alternative embodiments, the control logic 300 may include initiating one or more control actions when it is determined that the sizes of the soil clods fall outside of the predetermined size range. For example, the computing system 210 may be configured to initiate a notification to an operator of the agricultural vehicle 10 and/or agricultural implement 12 that the sizes of the soil clods fall outside of the predetermined size range. Specifically, the computing system 210 may be configured to transmit instructions to the user interface 220 (e.g., via the communicative link 202) instructing the user interface 220 to initiate a notification to the operator of the agricultural vehicle 10 and/or implement 12 (e.g., by causing a visual notification or indicator to be presented to the operator) indicating that the sizes of the soil clods fall outside of the predetermined size range.
Alternatively, or additionally, the computing system 210 may be configured to automatically adjust the ground speed at which the agricultural vehicle 10 and/or implement 12 is traveling across the field when it is determined that the sizes of the soil clods fall outside of the predetermined size range. Specifically, the computing system 210 may be configured to transmit instructions to the engine 36 and/or the transmission 38 (e.g., via the communicative link 202) instructing the engine 36 and/or the transmission 38 to adjust their operation. For example, the computing system 210 may instruct the engine 36 to vary its power output and/or the transmission 38 to upshift or downshift to increase or decrease the ground speed and/or stop/halt movement of the agricultural vehicle 10 and/or the implement 12. However, in alternative embodiments, the computing system 210 may be configured to transmit instructions to any other suitable components (e.g., braking actuators) of the agricultural vehicle 10 and/or the implement 12 such that the ground speed of the agricultural vehicle 10 and/or the implement 12 is adjusted. Furthermore, it should be appreciated that any other suitable parameter(s) the agricultural vehicle 10 and/or the implement 12 may be adjusted when it is determined that sizes of the soil clods fall outside of the predetermined size range.

Additionally, at (404), the method 400 may include determining the sizes of the soil clods based on the received image data. For instance, as indicated above, in several embodiments, the computing system 210 may be configured to determine the sizes of the soil clods based on the received image data.
Moreover, at (406), the method 400 may include controlling an operation of an actuator of the agricultural implement to adjust a position of the leveling disk gang assembly within a plane defined by a longitudinal direction extending parallel to the direction of travel and a lateral direction perpendicular to the longitudinal direction based on the determined sizes of the soil clods. For instance, as indicated above, in several embodiments, the computing system 210 may be configured to control the operation of the actuator(s) 42 of the agricultural implement 12 to adjust the position(s) of the leveling disk gang assembly(ies) 82 within the plane 78 defined by the longitudinal direction 86 and the lateral direction 88 based on the determined sizes of the soil clods.
It is to be understood that the steps of the control logic 300 and the method 400 are performed by the computing system 210 upon loading and executing software code or instructions which are tangibly stored on one or more tangible computer readable media, such as one or more magnetic media (e.g., a computer hard drive(s)), one or more optical media (e.g., an optical disc(s)), solid-state memory (e.g., flash memory), and/or other storage media known in the art.

The computing system 210 loads the software code or instructions via a direct interface with the one or more computer readable media or via a wired and/or wireless network. Upon loading and executing such software code or instructions by the computing system 210, the computing system 210 may perform any of the functionality of the computing system 210 described herein, including any steps of the control logic 300 and the method 400 described herein.
