The present disclosure relates to systems and methods for automatically positioning a moldboard of an industrial machine, including automatically positioning a moldboard of a motor grader relative to a wing of the motor grader.
Industrial machines, such as motor graders, are frequently employed to level, smooth, or otherwise at least partially remove materials, such as dirt, gravel, snow, etc., from ground surfaces, such as roads. Some motor graders include a moldboard mounted to a front frame, and a wing mounted to a side of the motor grader. However, it can be difficult for operators to position the moldboard relative to the wing when in operation. In operation, an improperly positioned moldboard can damage the moldboard, the wing, and/or the motor grader.
U.S. Pat. Pub. No. 2007/0068049 A1 to Quenzi (hereinafter “Quenzi”) describes a plow assembly including a pair of plow wings which are pivotally mounted at opposite ends of a center plow. In particular, Quenzi describes that each of the plow wings may pivot between a forwardly angled position and an aligned position, and the plow assembly may pivot a trailing plow wing in response to the center plow being urged or angled toward that side of the vehicle. However, Quenzi does not disclose adjusting the center plow based on the position of the plow wings. Additionally, Quenzi does not disclose adjusting the center plow or the plow wings based on operating thresholds.
In some embodiments, a computer-implemented method for automatically adjusting a moldboard of a motor grader can include receiving one or more identifiers corresponding to a configuration of the motor grader. The motor grader can include a rear frame, a front frame pivotably coupled to the rear frame, and a moldboard assembly coupled to the front frame. The moldboard assembly can include the moldboard, a drawbar, a circle, and a plurality of actuators each operably coupled to at least one of the moldboard, the drawbar, and the circle. The motor grader can further include a wing assembly coupled to the rear frame and to the front frame, and the wing assembly can include a wing. The method can further include determining, based on the one or more identifiers, a first orientation of the moldboard relative to the wing. If the first orientation is not within an operating threshold, the method can include at least one of the following: (i) selecting, based on the one or more identifiers, at least one of the plurality of actuators, and/or (ii) actuating the selected actuator to move the moldboard from the first orientation to a second orientation relative to the wing. In some embodiments, the second orientation of the moldboard can be within the operating threshold.
In some embodiments, a system for automatically adjusting a moldboard of a motor grader can include one or more processors, and one or more memory devices having stored thereon instructions that when executed by the one or more processors cause the one or more processors to perform at least one of the following: (i) receive one or more identifiers corresponding to a configuration of the motor grader; (ii) determine, based on the one or more identifiers, a first orientation of a moldboard of the motor grader relative to a wing of the motor grader; and, if the first orientation is not within an operating threshold; (iii) select, based on the one or more identifiers, at least one of a plurality of actuators of the motor grader; and/or (iv) actuate the selected actuator to move the moldboard from the first orientation to a second orientation relative to the wing, wherein the second orientation is within the operating threshold. In some embodiments, the motor grader can include: (i) a rear frame; (ii) a front frame pivotably coupled to the rear frame; (iii) a moldboard assembly coupled to the front frame and including the moldboard, a drawbar, a circle, and the plurality of actuators, individuals ones of which can be operably coupled to at least one of the moldboard, the drawbar, and the circle; and (iv) a wing assembly coupled to the rear frame and to the front frame, the wing assembly including the wing.
In some embodiments, an apparatus for automatically adjusting a moldboard can include a motor grader and one or more non-transitory computer-readable media. The motor grader can include a rear frame; a front frame pivotably coupled to the rear frame; a moldboard assembly coupled to the front frame and including the moldboard, a drawbar, a circle, and a plurality of actuators, individual ones of which can be operably coupled to at least one of the moldboard, the drawbar, and the circle; a wing assembly coupled to the rear frame and to the front frame and including a wing, and one or more sensors configured to determine a configuration of the motor grader. The one or more non-transitory computer readable media can store computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations including at least one of the following: (i) receive, via a controller communicatively coupled to the one or more sensors, one or more identifiers corresponding to a configuration of the motor grader; (ii) determine, via the controller and based at least in part on the one or more identifiers, a first orientation of the moldboard relative to the wing; and if the first orientation is not within an operating threshold; (iii) select, based on the one or more identifiers, at least one of the plurality of actuators; and/or (iv) actuate the selected actuator to move the moldboard from the first orientation to a second orientation relative to the wing. In the second orientation, the moldboard can be within the operating threshold.

The moldboard 112 can be coupled (e.g., operably, rotatably, etc.) to a circle 116. The circle 116 can be coupled (e.g., operably, rotatably, etc.) to a drawbar 114, and the drawbar 114 and/or the circle 116 can be coupled (e.g., operably, rotatably, etc.) to the front frame 104. In some embodiments, the moldboard assembly 110 can further include a linkbar 115 coupled (e.g., operably, rotatably, etc.) to the circle 116 and/or the drawbar 114.
The wing assembly 130 can be coupled (e.g., operably, rotatably, etc.) to the rear frame 102 and/or the front frame 104. The wing assembly 130 can include a wing 132 having a first (e.g., right, heel, trailing, etc.) end portion 132a, and second (e.g., left, toe, leading, etc.) end portion 132b, and a wing edge 133 (e.g., a wing cutting edge) therebetween. The wing edge 133 can be generally or substantially aligned with or parallel to an axis AW of the wing (“the wing axis AW”). In some embodiments, the first end portion 132a and/or the second end portion 132b can each have a profile or contour. In the illustrated embodiment, for example the first end portion 132a has a first curvature C2a and the second end portion 132b has a second curvature C2b. The second curvature C2a can be the same as or different than the first curvature C2b.
As best seen in
The circle rotation actuator 118 can couple (e.g., operably, etc.) the circle 116 and the drawbar 114, and can be configured to rotate the circle 116 and the moldboard 112 relative to the drawbar 114 and/or the front frame 104.
The drawbar centershift actuator 120 can couple (e.g., operably, etc.) the drawbar 114 and the front frame 104, and can be configured to rotate the drawbar 114 relative to the front frame 104 to move the circle 116 and the moldboard 112 in a lateral direction L about a pivot point (not shown) relative to the front frame 104 (e.g., move the circle 116 and the moldboard 112 to the left and/or right of the front frame 104).
The first moldboard lift actuator 122a and the second moldboard lift actuator 122b (collectively, “the moldboard lift actuators 122”) can couple (e.g., operably, etc.) the front frame 104 and the drawbar 114, and can be configured to shift the drawbar 114, the circle 116, and/or the moldboard 112 relative to the front frame 104. In at least some embodiments, for example, and with reference to
The moldboard sideshift actuator 124 can be coupled (e.g., operably, etc.) to the circle 116 and the moldboard 112, and can be configured to move (e.g., shift) the moldboard 112 along the moldboard axis AM (
The moldboard pitch actuator 126 can be coupled to the circle 116 and the moldboard 112, and can be configured to rotate or pivot the moldboard about the moldboard axis AM (
The linkbar actuator 128 can be coupled (e.g., operably, etc.) to the linkbar 115 and the front frame 104, and can be configured to control the linkbar 115. In at least some embodiments, for example, the linkbar 115 is designed to increase a range of motion of the moldboard 112, e.g., to increase a lateral or horizontal reach of the moldboard 112 from a centerline or longitudinal axis of the machine 100 and/or to allow steeper moldboard angles (e.g., relative to the centerline of the machine and/or a ground surface). The linkbar 115 can include one or more holes or positions that can correspond to an offset of the circle from the front frame 104 center line. Accordingly, actuating the linkbar actuator 128 can reposition the linkbar 115, which can increase the motor grader's productivity, e.g., when ditching, backsloping and/or moving large windrows.
Each of the moldboard actuators can include one or more motors, solenoids, pistons, hydraulics, gears, joints, a combination thereof, and/or any other suitable actuator.
As best seen in
In some embodiments, actuating the front frame articulation element 140 to rotate the front frame 104 (e.g., during operation of the machine 100) can cause a corresponding movement of the moldboard assembly 110 and/or one or more components thereof. This can result in the moldboard 112 being angled, spaced apart from, or otherwise misaligned relative to the wing 132. For example, rotating the front frame 104 can result in a corresponding rotation of the moldboard assembly 110 and/or the moldboard 112. Accordingly, the orientation of the moldboard 112 can be adjusted (e.g., automatically adjusted) in response to the rotation of the front frame 104, e.g., to match an orientation (e.g., position, angle, pitch, etc.) of the wing 132. In the illustrated embodiment, for example, the front frame articulation element 140 has been actuated to rotate the front frame 104 (and the front frame axis LF) relative to the rear frame 102 (and the rear frame axis LR) to the front frame angle θA, and, in response, the moldboard 112 has been rotated to the moldboard angle θM (e.g., by actuating the circle rotation actuator 118 to rotate the circle 116) such that the moldboard axis AM is generally or substantially colinear or otherwise aligned with the wing axis AW.
In at least some embodiments, the machine 100, and/or one or more components thereof (e.g., the moldboard assembly 110, the wing assembly 130, etc.), can include a plurality of sensors (not shown). The sensors can be configured to measure, for example, the position and/or orientation of each of the components of the machine 100 relative to the rear frame 102, the rear frame axis LR, the front frame 104, and/or the front frame axis LF. The sensors can include rotation or angle sensors configured to measure a rotation or angle of a component, position sensors configured to measure a position of a component, actuation sensors configured to measure an extent or degree to which an actuator has been actuated, and/or any other suitable sensors. For example, the front frame 104 can include a first rotation sensor configured to measure the angle θA of the front frame axis LF relative to the rear frame axis LR, the moldboard assembly 110 can include a second rotation sensor configured to measure the moldboard angle θM, and/or the wing assembly 130 can include a third rotation sensor configured to measure the wing angle θW. Any of the actuators (e.g., the wing actuators, the moldboard actuators, etc.) described herein can include one or more sensors configured to determine a rotation, position, actuation, and/or orientation of the corresponding components.
In at least some embodiments, one or more dimensions of the machine 100 can be known or predetermined. This can include, for example, a length of the front frame 104, a length of the rear frame 102, a length of the moldboard 112, a length of the wing 132, the wing angle θW, etc. Accordingly, the orientation of the moldboard 112, the front frame 104, and/or the wing 132 can be geometrically determined in accordance with known mathematical principles (e.g., automatically determined) based on the plurality of sensors and/or the one or more dimensions of the machine 100.
In some embodiments, the machines 200a-d can include one or more operating thresholds T. The operating threshold(s) T can be used to determine whether the orientation of the moldboard 212 needs to be adjusted (e.g., based on the orientation of the wing 232). In at least some embodiments, for example, adjusting the moldboard 212 can include moving the moldboard 212 from a first orientation wherein at least a portion of the moldboard 212 is outside (e.g., beyond, not within, etc.) the operating threshold T to a second orientation wherein that portion is within the operating threshold T. Accordingly, as used herein, the moldboard 112 and/or the moldboard axis AM can be generally or substantially colinear or otherwise aligned with (e.g., matching) the wing 132 and/or the wing axis AW in the second orientation.
The operating threshold T can include a distance, a linear distance, an arc length, an angle, and/or any other suitable measurement. The operating threshold T can be defined relative to any component of the machine 100, such as the wing 132, the wing axis AW, the second end portion 132b of the wing 132, the wing edge 133, the rear frame 102, the rear frame axis LR, the front frame 104, the front frame axis LF, etc. In at least some embodiments, for example, the operating threshold T can be an angle relative to the wing axis AW of up to 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 10 degrees, 20 degrees, or any angle therebetween. In at least some embodiments, for example, the operating threshold T can be a distance from the second end portion 132b of the wing 132 of up to 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 100 mm, 200 mm, 300 mm, 400 mm, 500 mm, or any distance therebetween.

Although
In some embodiments, the moldboard 212 can be adjusted in response to one or more adjustments to the wing 232. In at least some embodiments, for example, the wing 232 can be moved from a first orientation to a second orientation, and, in response, the moldboard 212 can be moved from a third orientation to a fourth orientation where, in the third orientation, the moldboard 212 is outside the operating threshold T, and where, in the fourth orientation, the moldboard 212 is within the operating threshold T.
The moldboard sideshift identifier can correspond to the orientation and/or movement of the moldboard 112 in the direction S along the moldboard axis AM (
The left moldboard lift identifier can correspond to the orientation and/or movement of the second end portion 112b of the moldboard 112 in the vertical direction V (
The right moldboard lift identifier can correspond to the movement of the first end portion 112a of the moldboard 112 in the vertical direction V (
The circle rotation identifier can correspond to the angle or rotation of the circle 116 and moldboard 112 (e.g., the moldboard angle θM) relative to the drawbar 114 and/or the front frame 104 (e.g., in response to actuating the circle rotation actuator 118).
The drawbar centershift identifier can correspond to an angle or rotation of the drawbar 114 relative to the front frame 104 and/or the front frame axis LF (e.g., in response to actuating the drawbar centershift actuator 120).
The linkbar position identifier can correspond to a configuration of the linkbar 115 (e.g., in response to the linkbar actuator 128). In at least some embodiments, for example, the linkbar position identifier can correspond to the one or more holes or positions of the linkbar 115. In some embodiments, the linkbar position identifier can be defined relative to a reference or center hole of the linkbar 115 (e.g., first hole left of center hole, third hole right of center hole, etc.).
The frame articulation identifier can correspond to the angle θA of the front frame axis LF relative to the rear frame axis LR (e.g., in response to actuating the front frame articulation element 140).
The wing orientation identifier can correspond to the orientation of the wing 132 and/or the wing assembly 130. This can include, for example, the wing angle θW, movement of the second end portion 132b in the vertical direction V (
The machine mode identifier can correspond to a mode of the machine. In at least some embodiments, the machine can have one or more operating modes, and the method 300 can include adjusting the moldboard and/or the wing based on the one or more operating modes. In at least some embodiments, for example, the machine can include one or more of the following operating modes: (i) an off mode; (ii) an auto (active) mode; (iii) an auto (once) mode; and/or (iv) a suspend mode. In the off mode, the machine 100 can be configured to not adjust the position and/or orientation of the moldboard 112. In the auto (active) mode, the machine 100 can be configured to regularly or periodically adjust the position and/or orientation of the moldboard 112 relative to the wing 132. In the auto (once) mode, the machine 100 can be configured to adjust the position and/or orientation of the moldboard 112 relative to the wing 132 one time (e.g., once), but to not perform any further adjustments unless an additional input prompting further adjustments is received. In the suspend mode, the machine 100 can temporarily stop or suspend automatic repositioning of the moldboard. For example, in some embodiments, the wing assembly 130 can be transitioned to a “stowed” position where the wing 132 is rotated such that the wing axis AW is generally or substantially vertical (e.g., aligned with the vertical direction V). For example, in some embodiments, the wing assembly 130 can be transitioned to a “bench” position where the wing edge 133 remains parallel to a ground surface (e.g., a road, etc.) but the wing 132 is moved or elevated away from the surface. The suspend mode can be activated automatically, e.g., based on the identifiers corresponding to the position and/or configuration of the wing 132, or manually, e.g., by an operator. Accordingly, if one of the one or more identifiers in step 302 corresponds to the “Off” or “suspend” mode, the method 300 can include pausing or remaining at step 302 until an identifier corresponding to the “auto (active)” or “auto (once)” mode is received.
In some embodiments, the one or more identifiers can further include one or more dimensional identifiers. The dimensional identifier(s) can correspond to any of the measurements or dimensions of the machine described previously, such as the arm length identifier that corresponds to the arm length and/or a blade length identifier that corresponds to the blade length. In some embodiments, the one or more identifiers can further include one or more operating threshold identifiers. The operating threshold identifier(s) can correspond to the operating threshold(s) T. In some embodiments, the one or more identifiers can further include a front frame axis identifier. The front frame axis identifier can correspond to the front frame axis LF of
In some embodiments, at least one of the one or more identifiers can be predetermined (e.g., pre-programmed) based on the configuration of the machine. This can include at least one of the dimensional identifiers, the operating threshold identifier, the front frame axis identifier, the rear frame longitudinal axis identifier, and/or any other identifier described herein. In at least some embodiments, for example, the dimensional identifier(s) can be stored in a database, and step 302 can include accessing the database to determine the dimensional identifier(s).
At step 304, the method 300 can further include determining a first orientation of a moldboard relative to a wing. The first orientation can include one or more distances, linear distances, arc lengths, angles, etc. In some embodiments, the first orientation can be determined (e.g., automatically determined) based on the one or more identifiers of step 302. In at least some embodiments, for example, the one or more identifiers of step 302 can include the wing orientation identifier (corresponding to the wing angle θW), the circle rotation identifier (corresponding to the moldboard angle θM), the frame articulation identifier (corresponding to the front frame angle θA), and one or more dimensional identifiers (e.g., corresponding to the length of the front frame, the moldboard, and/or the wing), and the wing orientation identifier, the circle rotation identifier, the frame articulation identifier, and the one or more dimensional identifiers can be used to determine the first orientation of the moldboard.
At step 306, the method 300 can further include determining whether the first orientation of step 304 is within the operating threshold. If the first orientation is within the operating threshold, then the method 300 can return to step 302, and can further include repeating one or more of the steps 302, 304, and/or 306. If the first orientation is outside (e.g., beyond, not within, etc.) the operating threshold, then the method can continue to step 308. In some embodiments, the operating threshold in step 306 can correspond to one or more operating threshold identifiers received in step 302, and step 306 can include comparing the operating threshold identifier(s) to the determined first orientation of step 304. This is described in greater detail previously and with reference to
At step 308, the method 300 can further include transitioning the moldboard to a second orientation within the operating threshold of step 306. In some embodiments, transitioning the moldboard can include moving and/or rotating the moldboard relative to the wing and/or a front frame of the machine. In some embodiments, step 308 can include selecting at least one actuator of the moldboard actuator(s) and/or the wing actuator(s) based on the one or more identifiers of step 302. Selecting actuators is described previously and with reference to
In some embodiments, once the moldboard is in the second orientation, the method 300 can further include returning to step 302 and repeating one or more of the steps 302, 304, 306, and/or 308.
The system 400 can further include a moldboard controller 420. The moldboard controller 420 can be configured to perform one or more steps of the method 300. In at least some embodiments, for example, the moldboard controller 420 can receive one or more identifiers corresponding to a configuration of a machine (e.g., step 302). In at least some embodiments, for example, the moldboard controller 420 can determine a first orientation of the moldboard relative to the wing (e.g., step 304), e.g., based on the input(s) 410. In at least some embodiments, for example, the moldboard controller 420 can determine whether the first orientation is within an operating threshold (e.g., step 306).
The system 400 can further include one or more actuators 430. The actuator(s) 430 can be coupled (e.g., operatively, communicatively, etc.) to the moldboard controller 420. The actuator(s) 430 can include any of the moldboard actuators and/or wing actuators described previously. In at least some embodiments, for example, the actuator(s) 430 can include one or more of the following: (i) the moldboard lateral or sideshift actuator 124; (ii) the second (e.g., left) circle tilt or moldboard lift actuator 122b; (iii) the first (e.g., right) circle tilt or moldboard lift actuator 122a; (iv) the circle motor or rotation actuator 118; (v) the drawbar centershift actuator 120; (vi) the linkbar actuator 128; (vii) the front frame articulation element 140; (viii) the wing tilt actuator 136; (ix) the wing mast actuator 138; and/or any other actuator described herein. Accordingly, in some embodiments, the moldboard controller 420 can be configured to select and/or actuate one or more of the actuators 430, e.g., to transition the moldboard from a first orientation to a second orientation (e.g., step 308).
It is expected that machines and/or systems configured in accordance with embodiments of the present technology represent an improvement over traditional machines and/or systems. For example, when the moldboard 112 is within the operating threshold, it is expected that the machine 100 will remove material from a surface with greater efficiency. This is expected to improve productivity, reduce wear on the machine 100, the moldboard edge 113, and/or the wing edge 133, as well as improve the fuel efficiency of the machine compared to traditional machines and/or systems.
The techniques disclosed herein can be embodied as special-purpose hardware (e.g., circuitry), as programmable circuitry appropriately programmed with software and/or firmware, or as a combination of special-purpose and programmable circuitry. Hence, embodiments may include a machine-readable medium having stored thereon instructions which may be used to cause a computer, a microprocessor, processor, and/or microcontroller (or other electronic devices) to perform a process. The machine-readable medium may include, but is not limited to, optical disks, compact disc read-only memories (CD-ROMs), magneto-optical disks, ROMs, random access memories (RAMs), erasable programmable read-only memories (EPROMs), electrically erasable programmable read-only memories (EEPROMs), magnetic or optical cards, flash memory, or other type of media/machine-readable medium suitable for storing electronic instructions.
Several implementations are discussed below in more detail in reference to the figures.
CPU 510 can be a single processing unit or multiple processing units in a device or distributed across multiple devices. CPU 510 can be coupled to other hardware devices, for example, with the use of a bus, such as a PCI bus or SCSI bus. The CPU 510 can communicate with a hardware controller for devices, such as for a display 530. Display 530 can be used to display text and graphics. In some examples, display 530 provides graphical and textual visual feedback to a user. In some implementations, display 530 includes the input device as part of the display, such as when the input device is a touchscreen or is equipped with an eye direction monitoring system. In some implementations, the display is separate from the input device. Examples of display devices are: an LCD display screen; an LED display screen; a projected, holographic, or augmented reality display (such as a heads-up display device or a head-mounted device); and so on. Other I/O devices 540 can also be coupled to the processor, such as a network card, video card, audio card, USB, FireWire or other external device, sensor, camera, printer, speakers, CD-ROM drive, DVD drive, disk drive, or Blu-Ray device.
In some implementations, the device 500 also includes a communication device capable of communicating wirelessly or wire-based with a network node. The communication device can communicate with another device or a server through a network using, for example, TCP/IP protocols. Device 500 can utilize the communication device to distribute operations across multiple network devices.
The CPU 510 can have access to a memory 550. A memory includes one or more of various hardware devices for volatile and non-volatile storage, and can include both read-only and writable memory. For example, a memory can comprise random access memory (RAM), CPU registers, read-only memory (ROM), and writable non-volatile memory, such as flash memory, hard drives, floppy disks, CDs, DVDs, magnetic storage devices, tape drives, device buffers, and so forth. A memory is not a propagating signal divorced from underlying hardware; a memory is thus non-transitory. Memory 550 can include program memory 560 that stores programs and software, such as an operating system 562, Moldboard Controller 420 (which may include instructions for carrying out the methods of automatic moldboard positioning disclosed herein), and other application programs 566. Memory 550 can also include data memory 570 that can include database information, etc., which can be provided to the program memory 560 or any element of the device 500.
Some implementations can be operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with the technology include, but are not limited to, personal computers, server computers, handheld or laptop devices, cellular telephones, mobile phones, wearable electronics, gaming consoles, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, or the like.
In some implementations, server computing device 610 can be an edge server that receives client requests and coordinates fulfillment of those requests through other servers, such as servers 620A-C. Server computing devices 610 and 620 can comprise computing systems, such as device 500. Though each server computing device 610 and 620 is displayed logically as a single server, server computing devices can each be a distributed computing environment encompassing multiple computing devices located at the same or at geographically disparate physical locations. In some implementations, each server computing device 620 corresponds to a group of servers.
Client computing devices 605 and server computing devices 610 and 620 can each act as a server or client to other server/client devices. Server 610 can connect to a database 615. Servers 620A-C can each connect to a corresponding database 625A-C. As discussed above, each server 620 can correspond to a group of servers, and each of these servers can share a database or can have their own database. Databases 615 and 625 can warehouse (e.g., store) information. Though databases 615 and 625 are displayed logically as single units, databases 615 and 625 can each be a distributed computing environment encompassing multiple computing devices, can be located within their corresponding server, or can be located at the same or at geographically disparate physical locations.
Network 630 can be a local area network (LAN) or a wide area network (WAN), but can also be other wired or wireless networks. Network 630 may be the Internet or some other public or private network.
