Description

DESCRIPTION

[0001] This disclosure generally relates to agricultural machinery and in particular to header positioning devices and methods for operating header positioning devices. BACKGROUND OF THE REVELATION

[0002] Various agricultural vehicles perform a wide variety of agricultural operations, such as combine harvesters and rakes, which harvest a diverse range of crops. Depending on the crop or other factors, harvesting attachments used to harvest the crop can have significantly different geometries, weights, and forward speed requirements. Examples of harvesting attachment platforms include rotary mower conditioners and belt conveyors. SUMMARY OF THE REVELATION

[0003] This document provides exemplary devices, systems, and procedures. In some examples, a work machine header reel adjustment system includes a central frame. The system includes a plurality of elongated reel supports extending from the central frame. The system includes a plurality of reel brackets movably coupled to the reel supports. The system includes a displacement assembly extending from the central frame to the reel supports. The system includes one or more actuators coupled to the displacement assembly. The one or more actuators are designed to move the reel supports longitudinally along the plurality of reel supports through the displacement assembly. Each of the one or more actuators is designed to move a plurality of the reel supports.

[0004] In some examples, a method for moving a harvester header in a back-and-forth motion involves receiving back-and-forth motion instructions, at least partially based on an actual reel position and a target reel position.

[0006] To facilitate understanding of the principles of this disclosure, reference is now made to the implementations depicted in the drawings, and a specific language is used to describe them. It is understood, however, that these are not to be interpreted as limiting the scope of the disclosure. Any changes and further modifications of the described devices, systems, and methods, as well as any further application of the principles of this disclosure that are conceivable to a person skilled in the art in the field to which the disclosure relates, are fully permissible. In particular, it is entirely conceivable that the features, components, and / or steps described in relation to one implementation can be combined with the features, components, and / or steps described in relation to other implementations of this disclosure.

[0007] The terms relating to orientation, such as "upwards," "downwards," "upper," "lower," "over," "below," "front," "rear," "front," "back," "forwards," and "backwards," are used in the context of the examples provided as they would be understood by a person skilled in the art and are not intended to constitute a limitation of the disclosure. For a particular type of vehicle in a conventional configuration and orientation, operated in a conventional manner, a person skilled in the art would understand these terms in the context in which they are used and as they apply to that particular vehicle. For example, a person skilled in the art would understand what the forward direction means in the context of the direction in which a combine harvester normally moves when actively harvesting crops.Furthermore, an expert would understand what the reverse direction means for the agricultural harvesting vehicle during normal operation.

[0008] Furthermore, the term "forward" (and the like) refers to the forward direction of travel of a working machine (e.g., a harvester header or a combine harvester), for example, during harvesting operations. Likewise, the term "reverse" or "backward" (and the like) corresponds to a direction opposite to the forward direction of travel. Thus, for example, a "forward-pointing" marking on a harvester header can generally point in the direction the header moves during normal operation, while a "rearward-pointing" marking can generally point in the opposite direction.

[0009] Furthermore, the term "front" (and the like), as used herein, in relation to a working machine, unless otherwise defined or limited, indicates a direction of travel of the working machine during normal operation (e.g., the forward direction of travel of a harvesting vehicle carrying a header). Likewise, the expression "rear" (and the like) indicates a direction opposite to the forward direction of travel. In this context, for example, a "front" edge of a header, with respect to the direction of travel of the header during normal operation (e.g., carried by a combine harvester), may generally be located at the front of the header. Similarly, a "rear" edge of a header, with respect to the direction of travel of the header during normal operation, may generally be located at the rear of the header opposite the front edge.

[0010] Although the present disclosure relates to agricultural harvesting vehicles (e.g., combine harvesters), its scope is not limited to these. Rather, the disclosure encompasses machinery in numerous other industries where rearward visibility from the operator's seat is obstructed or otherwise impossible.

[0011] Some combine harvesters use headers that have multiple actuators to control the back-and-forth movement. Combine headers typically use a variety of actuators to move multiple header sections in a back-and-forth direction relative to the chassis of the agricultural machine. These actuators are often hydraulic, using a single fluid source in series with the numerous actuators, which can lead to inefficiencies. Therefore, conventional actuator systems for the back-and-forth movement of a header can result in the actuators being mistimed or delivering uneven force. Such missynchronization and uneven force distribution can cause the header sections to be misaligned, leading to mechanical problems or inefficient harvesting.Disclosed herein are devices, systems, and methods for moving a plurality of header mounts using an actuator and a mechanical displacement arrangement. The individual actuator and the displacement arrangement are designed to provide substantially uniform force and synchronized timing for the back-and-forth movement of a plurality of header sections, which can enable efficient and sustainable operation.

[0012] Fig. Figures 1A-1B show a side view of an agricultural vehicle 100 in the form of a combine harvester coupled with a harvesting header 104. Fig. Figures 1A-1B represent a specific example of an agricultural vehicle 100. The term "agricultural vehicle 100" can refer to a variety of other types of agricultural machinery and vehicles, including, but not limited to, forage harvesters and rakes. The depicted agricultural vehicle 100 can also be driven in both forward and reverse directions, as indicated by arrows 105 and 107, respectively. Fig. Figures 1A-1B are shown. This means that the agricultural vehicle can move forwards and backwards during the harvesting process, either to move out of or away from the harvested material.

[0013] Although in Fig. Figures 1A-1B do not show the following: It should be noted that the interior of the agricultural vehicle 100 contains at least a number of devices and / or systems, such as one or more threshing devices, separating devices, and cleaning devices. Furthermore, the agricultural vehicle 100 at least partially defines a container 120 used for storing cleaned harvested material (e.g., grain) before it is removed via an unloading conveyor 122 and loaded onto a transport vehicle.

[0014] The in Fig. The agricultural vehicle 100 shown in Figure 1 is equipped with an exemplary header 104 in the form of a belt header. However, the agricultural vehicle 100 can have a variety of other types of headers 104, including, but not limited to, corn pickers. The exemplary header 104 is coupled to a chassis 102 and positioned to pick up the crop material from the ground during operation of the agricultural vehicle 100. The header 104 shown also has a reel 106 for drawing crop material cut by a cutter bar 112 of the header into the header 104. As discussed below, the reel 106 can be selectively moved relative to a frame or support frame 110 of the header 104, for example, during operation of the agricultural vehicle 100.

[0015] The header 104 can also be moved relative to the ground surface to adjust its vertical height, also known as header height. According to certain examples, the header 104 can be pivoted about an axis relative to the chassis 102 via an actuator 118, for example, extending horizontally and perpendicular to the forward direction indicated by arrow 105. In some examples, this axis can coincide with the pivot axis of an upper guide roller of the central belt conveyor 116 of the header 104, in order to change the height of the header 104 above the field surface.

[0016] The harvesting header 104 is designed to convey cut crop material to an inclined conveyor 114. Furthermore, the harvesting header 104 can have one or more conveyor belts or screw conveyors, or a combination thereof, to transport crop material, and in particular cut crop material, along the harvesting header 104 and to the inclined conveyor 114. The minimum in Fig. The exemplary harvesting header 104 shown in Figures 1A-1B includes, for example, two outer belt conveyors 124, each connected to a drive 126 that provides power for the rotary motion of the drives of the outer belt conveyors 124. During the feeding of the crop material, the power provided by the drive 126 can accordingly be transmitted to each of the two outer belt conveyors 124 such that the upper surfaces of the belts of the outer belt conveyors 124 move inwards (i.e., as indicated by the arrows) to convey the crop, picked up by the reel 106 and cut by the cutter bar 112, to the center of the harvesting header 104. The crop material conveyed to the center of the harvesting header 104 is then conveyed on a belt of the central belt conveyor 116, driven by a drive 128, and transported to the rear into the inclined conveyor 114.

[0017] At least under certain circumstances, the position of the header 104 or the reel 106 can be adjusted to accommodate variations in terrain elevation and / or attributes, such as characteristics or properties, of the crop material, for example, plant height or growth habit. Regardless of the type of header 104 used, the header 104 or its associated components are also often positioned, at least when attempting to improve the operational efficiency of the header 104 and the corresponding crop yield, in a selected position relative to the adjacent ground surface and / or to an attribute of the crop material, such as plant height.The height of the soil surface or the associated attribute of the crop, as well as soil types, moisture levels, and nutrients, can vary across a field, among other properties. This can negatively affect the crop yield from the operation of the header if no appropriate action is taken. In some examples, the header 104 and the reel 106 can be moved relative to a frame 110 of the header 104 by actuating one or more actuators. A variety of different types of devices and combinations thereof can be used as actuators, including, among others, electrically operated linear actuators, a pneumatic actuator, or other hydraulically operated actuators, as well as combinations thereof.One or more of the actuators can therefore be, for example, a double-acting hydraulic or pneumatic cylinder that can be extended and retracted to vary its length. Such actuators can also include, among other devices, one or more associated pumps, motors, or control valves, as well as various combinations thereof, which are used to control the selective extension and retraction of such cylinders. In some examples, the number of actuators can vary.

[0018] As in Fig. As shown in Figure 2, a harvester header 200 can, in some examples, include a central section 202 and one or more wing sections 204. The wing sections 204 can be coupled to either side of the central section 202. In some examples, several central sections 202 and wing sections 204 can be coupled in a row.

[0019] In the Fig. In the example shown, the central section 202 includes a central frame 206, two reel supports 208, two reel brackets 210 which are slidably coupled to the reel supports 208, a displacement assembly 212, and an actuator 214 which is coupled to the displacement assembly 212. The central frame 206 is designed to be narrower than the wing sections 204 of the header 200. In some examples, the central frame 206 has a width designed to fit a desired cumulative width of the side sections within the header 200.

[0020] As in Fig. As shown in Figure 3, the central frame 206 can include a plurality of reel supports. The reel supports 208 are essentially rigid rods arranged on the central frame 206 and extending longitudinally with respect to the forward and reverse directions of operation of the working machine 100 and the header 200. The reel supports are designed to prevent the reel brackets 210 from sliding beyond the reel supports 208 in a forward direction. The reel supports 208 can be rigid supports designed to rigidly restrict a portion of the reel brackets 210 from moving in a back-and-forth direction. The reel supports 208 can be made of suitable rigid materials for a working machine application. For example, in some examples, the reel supports 208 can be made of aluminum, composite material, or steel.

[0021] As in Fig. As shown in Figure 3, the reel supports 210 can be sliding supports designed to accommodate a rotating reel assembly 211 of the combine harvester. Each reel support 210 includes a frame 213 that defines a channel to receive the reel frame. The reel supports 210 also include a reel receptacle 215 designed to receive a rotating assembly 211, allowing the rotating assembly 211 to rotate freely around the reel receptacle 215. The reel supports 210 are arranged opposite each other and spaced apart around the reel support frame 213, so that the reel supports 210 can be parallel to each other at any given time during the operation of the machine 100.The reel brackets 210 can be slidably coupled to the reel supports 208, allowing the reel brackets 210 to move essentially freely axially along the reel supports 208 in a back-and-forth direction, as specified by the displacement arrangement 212. In other examples, the reel brackets 210 can be rolled to the reel supports 208, allowing the reel brackets 210 to roll along at least one surface of the reel brackets 210 using a suitable rolling mechanism. For example, the reel brackets 210 can roll along the reel supports 208 using one or more rollers or one or more bearings. The reel brackets 210 can be formed from suitable rigid materials to hold the rotating combine harvester assembly 211 during operation. For example, in some examples, the reel brackets 210 can be made of materials such as aluminum or steel.

[0022] As in Fig. As shown in Figure 3, the displacement assembly 212 is designed to effect a forward-backward movement of a portion of the harvesting header 200, such as the rotating assembly 211. The displacement assembly 212 is further designed to provide movement of the first support and the second support using an actuator 214 to move a plurality of reel brackets. The displacement assembly 212 includes the connecting linkage 220 to transmit movement from the actuator 214 to a plurality of brackets, such as the reel brackets 210. The connecting linkage 220 transmits energy and provides the desired energy input and movement from the actuator 214 to the reel brackets 210.

[0023] The displacement arrangement 212 includes a rotator arrangement 216, a first arm and a second arm 218, and a single drive rod 221 (in Fig. (5 shown), which extends between the first arm and the second arm 218, such that the movement of the drive rod causes a substantially uniform movement of each of the first and second arms. The first arm and the second arm 118 are each coupled to the rotator assembly 216 via a connecting link 220, which directs the movement of the reel supports 210 along the reel supports 208. Accordingly, the rotator assembly 216 is movably connected to the actuator 214 via the arms 218, such that a linear movement of an actuator 214 causes a rotary movement of the rotator assembly 216, which further moves the arms 218 in a linear motion.

[0024] In the Fig. In the example shown, the rotator assembly 216 of the displacement assembly 212 is a mechanical system comprising a rotator arm coupled to the actuator 114. The rotator is designed to be a rotating element with an irregular shape, incorporating a rotator profile suitable for back-and-forth movement at a desired frequency and amplitude. Accordingly, the shape of the rotator is designed to control the movement of the arms in a desired back-and-forth direction. The arms 218 act as followers in the rotator assembly 216. One end of each arm 218 is rotatably coupled to the surface of the cam and moves the reel supports 210 based on the rotator profile.Accordingly, the displacement arrangement 212 can be designed to provide a desired ratio of rotational motion and linear motion for a specific combine harvester application in order to ensure a desired efficiency between the actuator 214 and the rotating arrangement 211.

[0025] Fig. Figure 3 shows the actuator 214. The actuator 214 is designed to exert a displacement force on the rotating arrangement 211 in order to move the rotating arrangement 211 in a desired direction. In the Fig. In the example shown in Figures 3-4, the actuator 214 is designed to move the rotating assembly 211 in the back-and-forth direction. In some examples, the actuator 214 may be designed to provide a force to move a header assembly 200 during, before, or after combine harvester operation. For example, the actuator 214 may be a linear actuator or a rotary actuator designed to move at least part of the header 200 in the back-and-forth direction while resisting objects that may oppose the back-and-forth movement. For example, the actuator 214 may be designed to move the rotating assembly 211 through crop material such as corn.

[0026] The actuator 214 can be a hydraulic actuator 214. Based on the configuration of the header 200 for the desired combine harvester operation, the actuator 114 can be coupled to the rotator at a variety of points. For example, as shown in Fig. As shown in Figures 3-4, the actuator 214 is coupled to one of the reel supports 208, such that the actuator 214 is located on one of the sides of the central section 202. In some examples, the actuator can be located at different points on the harvester header 200. For example, as shown in Fig. As shown in Figure 6, the actuator 214 is located in the middle of the central section 202.

[0027] In examples involving a hydraulic actuator, the actuator 214 is designed to convert the pressure of hydraulic fluid from a fluid system in the working machine into a mechanical back-and-forth motion through the displacement arrangement 212. The hydraulic actuator can utilize hydraulic fluid from other parts of the combine harvester system or from a separate fluid reservoir to provide the required pressure. Accordingly, the pressurized fluid is used to transmit power through the header 200. In some examples, the hydraulic system of the hydraulic actuator may include an electronic pressure regulator, allowing the hydraulic actuator to be controlled and / or modulated based on instructions from an electronic control device.

[0028] In some examples, the actuator 214 can be an electronic actuator. For example, the electronic actuator can be designed to adjust the position of the harvesting header using an electrical power source. In some examples, the actuator 214 can provide controlled and / or modulated movement for the harvesting header 200 based on instructions from an electronic control device. In some examples, the electronic actuator can be a linear actuator (spindle- or belt-driven) or a rotary actuator (motor) that receives power from a power source of the agricultural machine 100 or a separate power source.In some examples, the electronic actuator may include a motor (such as a stepper motor, servo motor, or DC motor), a mechanical transmission system (such as a leadscrew, ball screw, or belt drive), and a control system (such as a microcontroller or a dedicated driver). In examples using a linear actuator, the rotational motion of the motor can be converted by the mechanical transmission system into a linear motion, which is transmitted to the cams of the displacement assembly 212.

[0029] In some examples, the working machine 100 includes a central control device 123. The central control device 123 can be designed to provide instructions and control processes for the working machine. The central control device 123 can control the actuator 214. For example, the central control device 123 can send electronic signals to a hydraulic actuator with an electronic valve or to an electronic actuator. Accordingly, the central control device 123 can transmit instructions to the actuator 214 to provide desired forward-backward movement instructions for combine harvester operation. Fig. Figure 7 shows example steps for a procedure for moving a harvesting header in a back-and-forth motion.

[0030] In step 702 of the in Fig. In the example shown, the control device 123 can receive forward-backward movement instructions from an operator. The forward-backward movement instructions can be based, at least in part, on a determined reel position and a desired reel position. The determined reel position can be a reel position detected at a specific time. The desired reel position can be an extended or retracted position of the rotating arrangement 211 in the forward-backward directions, based on a determination by an operator or processor. For example, the central control device 123 can determine a position of the harvester head relative to an agricultural machine at a specific time and a desired position of the harvester head relative to the agricultural machine based on the requirements of a future combine harvester operation.

[0031] In step 704 of the in Fig. In the example shown in Figure 7, the control device 123 can provide instructions for activating one or more of the actuators 214 coupled to the plurality of reel mounts 210 via the displacement arrangement 212. In some examples where the actuator is a hydraulic actuator, the control device 123 can be configured to determine and / or transmit instructions to the actuator 214 for a desired actuator pressure of the hydraulic fluid as well as the effective area or geometry of the piston or rotor. In examples involving an electronic actuator, the central control device 123 can transmit instructions to transfer a desired amount of electrical energy to the actuator 214. In some examples, the instructions can be determined based on a combine harvester application.For example, instructions during combine harvester operation can be dynamically adjusted based on desired harvesting parameters and / or dynamic field conditions.

[0032] In some examples, the central control device 123 may be configured to move the actuator 214 with a desired power, based at least in part on the specifications of the header, such as its weight and size. In some examples, the instructions may be to move the actuator 214 based on a desired distance and angle of movement relative to a ground surface and / or the working machine 100. The central control device 123 may also determine a desired force of movement, based at least in part on the characteristics of the displacement arrangement 212. For example, the displacement arrangement 212 may distribute the force from the actuator 214 in a desired direction among a plurality of reel supports 210. Accordingly, the central control device 123 may determine the desired force based at least in part on the distribution of the force by the displacement arrangement 212.

[0033] In step 706 of the in Fig. In the example shown in Figure 7, the control device 123 can receive feedback from one or more sensors of the working machine, providing feedback on the forward-backward reel position, such as the position relative to a ground surface and / or the working machine. In some examples, the feedback can be based at least partially on the relative positions of the displacement assembly 212 and the reel supports 210, so that the control device 123 can provide further control instructions based at least partially on the feedback and a target position of the harvester header. In some examples, the sensors can be one or more cameras, RFID sensors, or other suitable sensors to determine the position of the parts of a working machine relative to each other.

Furthermore, the data processing system can include a frontend component, such as a client computer with a graphical user interface or a web browser, through which a user can interact with the computer. The system components can be interconnected via any form or medium of wired or wireless digital data communication (or a combination thereof) in a communication network.Examples of communication networks include a local area network (LAN), a radio access network (RAN), a man-city network (MAN), a wide area network (WAN), Worldwide Interoperability for Microwave Access (WiMAX), a wireless local area network (WLAN) (e.g., using 802.11 a / b / g / n or 802.20 or a combination of protocols), the entire internet or a portion thereof, or any other communication system or systems at one or more locations (or a combination of communication networks). The network can communicate, for example, using IP (Internet Protocol) packets, frame relay frames, ATM (Asynchronous Transfer Mode) cells, voice, video, data, or a combination of communication methods between network addresses.

[0043] Wireless connections within the scope of this disclosure include wireless protocols such as 802.15 protocols (e.g. BLUETOOTH®), 802.11 protocols, 802.20 protocols (e.g. WI-FI®) or a combination of different wireless protocols.

[0044] A data processing system can comprise clients and servers. A client and a server can be physically separated and typically communicate with each other via a communication network. The relationship between client and server arises from computer programs running on the respective computers, thus establishing a client-server relationship.

[0045] Cluster file systems can be any type of file system that can be accessed by multiple servers for reading and updating. Locking or consistency tracking may not be necessary, as locking an Exchange file system can be done at the application level. Additionally, Unicode data files can differ from non-Unicode data files.

[0046] Although this specification contains many specific implementation details, these should not be interpreted as limitations on the scope of what can be claimed, but rather as descriptions of features that may be specific to certain implementations. Certain features described in this specification in connection with separate implementations may also be implemented in combination within a single implementation. Conversely, various features described in connection with a single implementation may also be implemented in multiple implementations, individually or in any suitable subcombination.Furthermore, although previously described features may be described as acting in certain combinations and may even have been originally claimed as such, in some cases one or more features from a claimed combination may be removed from the combination, and the claimed combination may refer to a subcombination or a variant of a subcombination.

[0047] Specific implementations of the subject matter have been described. Other implementations, modifications, and permutations of the described implementations fall within the scope of the following claims, as is obvious to a person skilled in the art in the relevant field. Even if operations are shown in the drawings or claims in a particular sequence, this is not to be understood as meaning that these operations must be carried out in the sequence shown or in any particular order, or that all the operations shown must be carried out (some operations may be considered optional) to achieve the desired results. Under certain circumstances, multitasking or parallel processing (or a combination of multitasking and parallel processing) may be advantageous and may be carried out as needed.

[0048] Furthermore, the separation or integration of different system modules and components in the implementations described above should not be understood as requiring such separation or integration in all implementations, and it should be assumed that the described program components and systems can generally be integrated into a single software product or packaged into multiple software products.

[0049] Accordingly, the example implementations described above do not define or limit the present disclosure. Other changes, substitutions, and modifications are also possible without deviating from the fundamental idea and scope of the present disclosure.

[0050] Furthermore, each claimed implementation is considered applicable to at least one computer-implemented method; a non-volatile, computer-readable medium storing computer-readable instructions for carrying out the computer-implemented method; and a computer system including a computer memory interoperably coupled with a hardware processor designed to execute the computer-implemented method or the instructions stored on the non-volatile, computer-readable medium.

[0051] Although the foregoing describes exemplary implementations of the present disclosure, these descriptions are not to be construed as limitations. Rather, other variations and modifications may be made without deviating from the scope of protection and nature of the present disclosure, as defined in the pending claims.
