[0028] Referring now to
[0029] In various embodiments, the machine 10 may include a chassis 12 configured to support or couple to a plurality of components. For example, front and rear wheels 14, 16 may be coupled to the chassis 12. The wheels 14, 16 may be configured to support the machine 10 relative to a ground surface and move the machine 10 in a forward direction of travel as indicated by arrow 18 in
[0030] The chassis 12 may also support a cab 20, or any other form of operator's station, which provides various control or input devices 22 (e.g., levers, pedals, control panels, buttons, and/or the like) for providing various notifications to an operator and/or permitting the operator to control the operation of the machine 10. For instance, as shown in
[0031] The chassis 12 may also support a tank 26 and a boom assembly 28 mounted to the chassis 12. The tank 26 is generally configured to store or hold an agricultural product, such as a pesticide, a fungicide, a rodenticide, a fertilizer, a nutrient, and/or the like. The agricultural product stored in the tank 26 may be dispensed onto the underlying ground surface (e.g., plants and/or soil) through one or more nozzle assemblies 30 mounted on the boom assembly 28.
[0032] As shown in
[0033] As shown in
[0034] In other examples, the boom arm 34, 36 may include more or less than two (2) sections. Inner end portions of the primary boom section 38 for each boom arm 34, 36 may be coupled to the frame 32 through a lift arm assembly 44. Hinge joints 46 may connect the outer end portions of the primary boom sections 38 with the inner end portions of the outer boom sections 40. In some instances, the hinge joints 46 can include one or more breakaway joints 48 may interconnect the outer end portions of the outer boom section 40 with the inner end portions of the breakaway boom sections 42. Each breakaway joint 48 is configured to retain the breakaway boom sections 42 in an extended, default position, for example, with the breakaway boom section 42 extending from the outer boom section 40 or any other boom section. However, the breakaway joint 48 is configured to allow the breakaway boom section 42 to move relative to the outer boom section 40 when contact is made with the breakaway boom section 42. In some examples, the breakaway joint 48 may include a hinge assembly 50 that guides the movement of the breakaway boom section 42 and may define a pivot axis 54 about which the breakaway boom section 42 pivots. The breakaway joint 48 may also include a damper system 52 that is positioned proximate to the breakaway joint 48.
[0035] Referring now to
[0036] A second hinge joint 78 may be operably coupled with the inner bracket 56 and the outer bracket and define a second movement axis 80. The second movement axis 80 may be fore or aft of the pivot axis 54. In some cases, the inner bracket 56 may be operably coupled with a rotation member 82 and the outer bracket 58 may include a projection 84 that may be coupled to the rotation member 82. The inner bracket 56 may further include a guide 86 that may further support the protection as the breakaway boom section 42 moves between various positions. Additionally or alternatively, in some examples, the outer bracket may include and/or support a hinge stop 88. A bumper 90 or other contact device may be operably coupled with and/or integrally defined with the inner bracket 56. When the breakaway boom section 42 is in a first, default position, the hinge stop 88 may contact and/or be positioned at a first distance from the bumper 90. When the breakaway boom section 42 is in a section position, the hinge stop 88 may separate from the bumper 90 and positioned at a second distance from the bumper 90. In various examples, the first distance may be less than the second distance.
[0037] With further reference to
[0038] In various instances, the first damper bracket 92 may include a base 98, a first wall 100 extending from the base 98, a second wall 102 spaced from the first wall 100 and extending from the base 98, and one or more connectors 104 operably coupled with the first wall 100 and the second wall 102. Each of the base 98, the first wall 100, and the second wall 102 may be integrally formed or later attached to one another. The first damper bracket 92 may also include a damper connection segment 106 operably coupling a cylinder 144 of the damper 96, and/or a latch member 122 connection segment 108 operably coupling the latch member 122 to the first damper bracket 92. As shown, in some examples, the damper 96 may be at least partially positioned between the two walls of the first damper bracket 92.
[0039] In some cases, the second damper bracket 94 may include a base 110, a first wall 112 extending from the base 110, and/or a second wall 114 spaced from the first wall 112 and extending from the base 110. Each of the base 110, the first wall 112, and the second wall 114 may be integrally formed or later attached to one another. The second damper bracket 94 may also include one or more connectors 116 operably coupled with the first wall 112 and the second wall 114. A linkage connection segment 118 may operably couple a linkage 120 to the second damper bracket 94.
[0040] As shown, in some examples, a latch member 122 may be rotatably coupled with the first damper bracket 92. In some examples, the latch member 122 may include a pair of latch member walls 124, 126, one or more connection structures 128, and a plurality of pins 130 operably coupled with each of the latch member walls 124, 126. For example, the latch member 122 may be rotatably coupled with the first damper bracket 92 at a first damper joint 132. The damper 96 may also be coupled with the first damper bracket 92, the outer boom section 40, and/or any other component of the boom assembly 28, and the latch member 122 at a second damper joint 134. In various examples, the second damper joint 134 may be positioned further from the frame 32 (
[0041] As shown, in some examples, the linkage 120 may be operably coupled with the latch member 122 on a first end portion thereof and the second damper bracket 94 on a second end portion thereof. In some cases, the coupling of the linkage 120 with the latch member 122 may form a third damper joint 136. In various examples, the third damper joint 136 may be positioned further from the frame 32 of the boom assembly 28 than the first damper joint 132 and/or the second damper joint 134 in a lateral direction. Further, the coupling of the linkage 120 with the second damper bracket 94 may form a fourth damper joint 138. In some cases, the fourth damper joint 138 may be configured to allow rotation and tilt of the breakaway boom section 42 as the breakaway boom section 42 is moved from its default position to a deflected position, which may be along line 140. In various examples, the fourth damper joint 138 may be positioned further from the frame 32 of the boom assembly 28 than the first damper joint 132, the second damper joint 134, and/or the third damper joint 136 in a lateral direction. In various examples, the fourth damper joint 138 may be positioned vertically above the first damper joint 132, the second damper joint 134, and/or the third damper joint 136.
[0042] Referring still to
[0043] In several examples, the damper 96 may correspond to a suitable hydraulic actuator. In such examples, the damper 96 may include both a cylinder 144 configured to house a piston 146 and a rod 148 coupled to the piston 146 that extends outwardly from the cylinder 144. Additionally, the damper 96 may include a piston-side chamber 150 and a rod-side chamber 152 defined within the cylinder 144. As is generally understood, by regulating the pressure of the fluid supplied to one or both of the cylinder chambers 150, 152, the actuation of the rod 148 may be controlled. As shown in
[0044] In some examples, the machine 10 may also include a hydraulic system 154 which provides a source of pressurized hydraulic fluid for driving and/or positioning the damper 96. In such examples, the hydraulic system 154 may be utilized to control the force and the speed at which the damper 96 resists movement of the breakaway boom section 42 and/or moves the breakaway boom section 42 to a default position once the breakaway boom section 42 is deflected. The position of the boom assembly 28 may be determined based on various operating conditions, user-defined preferences, and/or machine-learned methods and algorithms that utilize one or several machine learning techniques including, for example, decision tree learning, including, for example, random forest or conditional inference trees methods, neural networks, support vector machines, clustering, and Bayesian networks. These algorithms may include computer-executable code that may be retrieved by the computing system and/or through a network/cloud and may be used to evaluate and update the boom deflection model. In some instances, the machine learning engine may allow for changes to the hydraulic pressure within the damper system 52 to be performed without human intervention.
[0045] In various examples, a computing system 156 may be communicatively coupled to the hydraulic system 154 and/or the damper 96. In general, the computing system 156 may include any suitable processor-based device, such as a computing device or any suitable combination of computing devices. Thus, in several examples, the computing system 156 may include one or more processors and associated memory 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 of the computing system 156 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 disk, a compact disc-read only memory (CD-ROM), a magneto-optical disk (MOD), a digital versatile disc (DVD) and/or other suitable memory elements. Such memory may generally be configured to store suitable computer-readable instructions that, when implemented by the processors, configure the computing system 156 to perform various computer-implemented functions, such as one or more aspects of the data processing algorithm(s) and/or related method(s) described below. In addition, the computing system 156 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.
[0046] In several examples, the computing system 156 may correspond to an existing controller of the agricultural machine 10, or the computing system 156 may correspond to one or more separate processing devices. For instance, in some examples, the computing system 156 may form all or part of a separate plug-in module or computing device(s) that is installed relative to the machine 10 or the boom assembly 28 to allow for the disclosed agricultural system and method to be implemented without requiring additional software to be uploaded onto existing control devices of the machine 10 or the boom assembly 28.
[0047] In various examples, the computing system 156 may implement machine learning engine methods and algorithms that utilize one or several machine learning techniques including, for example, decision tree learning, including, for example, random forest or conditional inference trees methods, neural networks, support vector machines, clustering, and Bayesian networks. These algorithms may include computer-executable code that may be retrieved by the computing system 156 and may be used to generate a predictive evaluation of the alterations to the damper system 52. For instance, the computing system 156 may be configured to alter a default position of the piston 146 relative to the cylinder 144 based on various conditions.
[0048] Referring now to
[0049] As illustrated in
[0050] At (204), the method 200 may include returning the breakaway boom section to a default position by rotating a latch member relative to a first damper bracket to cause a positional change in a linkage that is operably coupled with an outer bracket and the latch member with a damper system. In some cases, returning the breakaway boom section to a default position may further include, at (206), rotating a protrusion defined by an outer bracket operably coupled with the breakaway boom section within a guide defined by an inner bracket operably coupled with the inner boom section.
[0051] In various examples, a hydraulic pressure within the damper system may be varied to control the force or the speed at which the damper resists movement of the breakaway boom section. The boom assembly may be determined based on various operating conditions, user-defined preferences, and/or machine-learned methods and algorithms that utilize one or several machine learning techniques including, for example, decision tree learning, including, for example, random forest or conditional inference trees methods, neural networks, support vector machines, clustering, and Bayesian networks. These algorithms may include computer-executable code that may be retrieved by the computing system and/or through a network/cloud and may be used to evaluate and update the boom deflection model. In some instances, the machine learning engine may allow for changes to the hydraulic pressure within the damper system to be performed without human intervention.
