Field of the invention [001] The present invention relates to an agricultural vehicle and, more specifically, to an agricultural vehicle with a platform that has one or more movable wing sections.
Background of the invention [002] An agricultural harvester known as a "combined harvester" is historically referred to as such because it combines multiple harvesting functions with a single collection unit, such as harvesting, threshing, sorting and cleaning. A combine includes a platform that removes the crop from a field and a feeder housing that transports the harvest material to a threshing rotor. The threshing rotor rotates inside a perforated housing, which can be in the form of adjustable smugglers and performs a threshing operation at harvest to remove the grain. Once the grain is threshed, it falls through perforations in the smugglers on a grain separation tray. From the grain separation tray, the grain is cleaned using a cleaning system and is then conveyed to a grain tank on board the combine harvester. A cleaning fan blows air through the sieves to discharge the chaff and other debris towards the rear of the combine harvester. Grain-free crop material, such as chaff from the threshing section, proceeds through a waste system, which can use a straw cutter to process the non-grained material and route it out the rear of the harvester combined. When the grain tank is full, the combined harvester is positioned adjacent to a vehicle into which the grain is to be unloaded, such as a semi-trailer, grain trailer, linear truck or similar; and a discharge system on the combine harvester is
Petition 870180073508, of 08/21/2018, p. 13/35
2/13 activated to transfer the grain to the vehicle.
[003] To remove the crop material from the field, the combine harvester platform can be equipped with a set of cutting bars with many sharp cutting elements that retract laterally, in relation to a forward direction of travel, to cut the field culture material before entering the feeder housing. The platform may include a rotating drum with fork tines or the like to sweep the culture material for the cutting elements.
[004] To closely monitor the soil and produce a consistent cutting shank length, many agricultural harvesters have flexible cutting elements, such as cutters, that can flex during harvesting. The flexing of the cutting bar (or bars) can help to compensate for the irregularity of the terrain encountered by the platform when moving through a field. Some flexible cutting bars can allow, for example, 7.62 centimeters (3 inches) of displacement in any direction from a normal, uninflected position, allowing the cutter's flexible bar to compensate up to 15.24 centimeters (6 inches) ) of unevenness of the soil over a width of the platform.
[005] Recent trends in agricultural vehicles have resulted in agricultural harvesters with relatively wider platforms to allow more crop material to be cut at each pass of the harvester, reducing the number of passes required to harvest crop material in a field. For example, some platforms may be 13.72 meters (45 feet) wide or more. The width of the platform was increased in several ways, including a main section of the platform that joins one or more wing sections.
[006] While the extension of the platform allows fewer passes for the complete harvest of a field, several challenges are
Petition 870180073508, of 08/21/2018, p. 14/35
3/13 presented by the increase in the extension of the platform. As previously described, some flexible mowing bars can compensate for up to 15.24 centimeters (6 inches) of soil unevenness over a width of the platform. As the platform becomes wider, it has been found that more compensation for soil irregularity may be needed to allow the platform to consistently follow the soil due to many fields with more than 15.24 (6 inches) inches of deviation. ground at a width of 13.72 meters (45 feet) or more.
[007] What is needed in the technique, is an agricultural platform that can follow the soil in increasing widths of the platform.
Description of the Invention [008] In an exemplary embodiment formed in accordance with the present invention, a platform with at least one wing section or segment rotatablely coupled to a main section is provided by a connection with an upper bar and a lower bar .
[009] In another exemplary embodiment formed in accordance with the present invention, an agricultural platform is provided, which includes: a main section that includes a main frame that supports at least one cutting element; at least one wing section pivotally coupled to the main section and which includes a wing frame; and a swivel link coupled to at least one wing section with the main section, where the link includes an upper bar and a lower bar, both attached to the main frame and the wing frame, the upper bar defining a geometric axis upper bar and the lower bar defines a lower bar geometric axis that is not parallel to the upper bar geometric axis.
[010] In yet another exemplary embodiment formed in accordance with the present invention, an agricultural platform is provided,
Petition 870180073508, of 08/21/2018, p. 15/35
4/13 which includes: a main section that includes a main frame that supports at least one cutting element; at least one segment section pivotally coupled to the main section and which includes a segment frame; and a swivel connection coupled to at least one segment section with the main section, wherein the connection includes an upper bar and a lower bar which are both coupled to the main frame and the segment frame.
[011] A possible advantage of the exemplary embodiments formed in accordance with the present invention is the rotation behavior of at least one wing section in relation to the main section, which can be varied by changing the configuration and orientation of the upper bar and the bar bottom of the connection.
[012] Another possible advantage of the exemplary embodiments formed in accordance with the present invention is the orientation that at least one segment section can be controlled by an actuator connected to the segment bars or sections to alter the soil following the behavior of the platform.

Description of Realizations of the Invention [014] Referring now to the Figures and more particularly to Figure 1, an exemplary embodiment of an agricultural vehicle 100 in the form of a combine harvester is shown, which generally includes a chassis 102 and an agricultural platform 110 driven by the chassis 102, according to an exemplary embodiment of the present invention. Typically, the combine harvester 100 will include additional systems for the separation and handling of the harvested material, but these additional systems are omitted from the view for brevity of description. It should be noted that the platform 110 described and illustrated in this document does not necessarily need to be included in a combine harvester, but can be incorporated into other agricultural vehicles, such as harvesters.
[015] Platform 110 includes a main section 111 with a main frame 112 that drives one or more cutting elements 113 with sharp edges 114 to cut culture material as the vehicle 100 moves forward, indicated by the arrow F As shown, the cutting element 113 is a cutting bar, but other types of cutting elements can also be included in place of the cutting bar 113. In addition, while the
Petition 870180073508, of 08/21/2018, p. 17/35
6/13 platform 110 is shown in the exemplary realization of a grain platform for grain harvesting, in some exemplary embodiments formed in accordance with the present, the platform may be in the form of a corn platform equipped with one or more elements of cut appropriate for corn harvesting. As shown in Figure 1, main frame 112 can be rigidly connected to chassis 102 on a support 103, but this is an optional configuration. The main section 111 can have a pair of opposite side ends 115 and 116, with a wing section 120 and 130 pivotally coupled to each of the side ends 115, 116, respectively. As used herein, swiveled coupled means that each wing section 120, 130 can be connected to its respective side end 120,130 so that wing sections 120,130 can rotate during the path of vehicle 100, which will be described later in this document. Each of the wing sections 120, 130 has a respective wing frame 121, 131 that can also support the cutter bar 113, as shown, so that the pivoting motion of the wing sections 120, 130 can cause bending of the cutterbar cut 113 to follow the soil, as will be described later in this document. As shown, main section 111 can define a main section length MSL that can be greater than a wing section length WSL1, WSL2 of wing sections 120, 130; in some exemplary embodiments, one or more of the lengths of the wing section WSL1, WSL2 may be longer than the length of the main section MSL. In addition, while two wing sections 120, 130 are shown and described in the present document, it should be noted that vehicle 100 may include only one wing section or more than two wing sections, if desired.
[016] Referring now to Figure 2, an exemplary embodiment of a connection 200 swivelly coupled to one of the
Petition 870180073508, of 08/21/2018, p. 18/35
7/13 wing sections 120, 130 to main section 111 is shown. Although not shown in Figure 2, another connection similar to the swivel 200 shown in Figures 2 to 3 or another connection, can be used to swivel the wing section 130 to the main section 110. The connection 200 includes an upper bar 201 and a lower bar 202 which are both coupled to the wing frame 121 and the main frame 112. As shown, the upper bar 201 can be coupled to an upper main pivot 216 of the main section 111 and an upper wing pivot 223 of the section of wing 120 and lower bar 202 can be coupled to a lower main pivot 217 of main section 111 and a lower wing pivot 224 of wing section 120, as shown. The upper bar 201 and the lower bar 202 can both be formed as substantially rigid bars, that is, generally inflexible, with the upper bar 201 defining an upper bar length UL and the lower bar 202 defining a lower bar length LL which is the same as the top length of the UL bar. As the connection 200 includes the upper bar 201 and the lower bar 202 connected to the main frame 112 and the wing frame 121, frames 112, 121 and bars 201, 202 together can act as a four-bar connection between the section wing 120 and main section 111, as opposed to a more traditional hinge connection built into many platforms.
[017] To increase the flexion of the cutter bar 113 in sections of the cutter bar 113, starting from the main section 111 and now also with reference to Figure 3, the top bar 201 defines a geometric axis of the top bar UA1 and the bar lower 202 defines a lower bar geometric axis LA1 that is not parallel to the upper bar geometric axis UA1. As can be seen by comparing Figures 2 and 3, which has the upper bar geometric axis UA1 and the lower bar geometric axis LA1 not parallel to each other, as shown, it allows to rotate the wing section 120 in relation to the main section

111 to cause a lateral outer end 225 of the wing section 120 to increase more than an inner lateral end 226 of the wing section 120 with the upper wing pivot 223 and the lower wing pivot 224. Since the deviations in the ground can be more pronounced adjacent to the outer side end 225 of the wing section 120 compared to the inner side end 226 of the wing section 120, which has the outer side end 225 rising more than the inner side end 226 while turning the section wing 120, can allow increased effective bending of the cutter bar 113 and allow the cutter bar 113 to follow the ground more closely across an entire width W of the platform 110 (shown in Figure 1), especially when the width W platform 110 is relatively large.
[018] When the wing section 120 is relatively level with the main section 111, as shown in Figure 2, the wing section 120 can define a WLA wing longitudinal axis that is coaxial with a section's longitudinal main axis MLA main 111 and parallel to a ground plane GP on which vehicle 100 is at rest. The upper bar geometry axis UA1 of the upper bar 201 and the lower bar geometric axis LA1 of the lower bar 202 may also not be parallel to the longitudinal wing geometric axis WLA, so that the bar geometric axes UA1, LA1 of the respective bars 201, 202 are angled with respect to the longitudinal geometric axis of the WLA wing. In this sense, the upper bar geometrical axis UA1 of the upper bar 201 can form an upper bar angle aU with respect to the longitudinal wing geometry axis WLA and the lower bar geometric axis LA1 of the lower bar 202 can form a lower bar angle. aL in relation to the longitudinal geometric axis of the wing WLA, which can be different or equal to the angle of the upper bar aU. The upper bar angle aU can be varied, for example, by changing the length
Petition 870180073508, of 08/21/2018, p. 20/35
9/13 of upper bar UL of upper bar 201 and / or by adjusting the positions of the upper main pivot 216 and the upper wing pivot 223 in relation to each other. Similarly, the lower bar angle 1_ can be varied, for example, by changing the lower bar length LL of the lower bar 202 and / or by adjusting the positions of the lower main pivot 217 and lower wing pivot 224 with respect to one to the other. By adjusting the upper bar angle aU and the lower bar angle al_, the rotation behavior of the wing section 120 with respect to the main section 111 can be adjusted as desired. As noted in Figures 2 and 3, the connection of four bars 200 can be configured so that the upper bar geometric axis UA1 and the lower bar axis LA1 are kept in a non-parallel relationship with each other, regardless of the orientation of the wing section 120 in relation to main section 111. In some exemplary embodiments, the connection of four bars 200 can also be configured so that the upper bar angle aU and the lower bar angle al_ remain constant during the pivot of the section of wing 120 in relation to the main section
111. In an exemplary embodiment, platform 110 may include an actuator 230, shown in dashed lines, coupling the upper bar 201 to the lower bar 202 to maintain the non-parallel relationship and / or the upper bar angle aU and the bar angle lower al_, but it should be noted that actuator 230 is not necessary to maintain the non-parallel relationship between the upper bar 201 and the lower bar 202 or the corresponding bar angles aU and aL.
[019] In another exemplary embodiment of a platform 400 formed in accordance with the present invention and with reference now to Figure 4, the platform 400 may include a main section 401 which includes a main frame 402 which leads one or more cutting elements 403 , such as a cutting bar, a first segment section 410
Petition 870180073508, of 08/21/2018, p. 21/35
10/13 rotatable to main section 401 and which includes a first segment frame 411 and may also include a second segment section 420 pivotally coupled to the first segment section 410 and which includes a second segment frame 421. As shown , the main frame 402 of the main section 401 can include an upper main bar 404 and a lower main bar 405, wherein the main bars 404, 405 of the main frame 402 are connected, for example, to the chassis 102 of the agricultural vehicle 100. Similarly , the first segment frame 411 may include a first segment upper bar 412 and a first segment lower bar 413 and the second segment frame 421 may include a second segment upper bar 422 and a second segment lower segment 423. In some exemplary embodiments, the first segment frame 411 and / or the second segment frame 421 are formed to be substantially rigid ie, resistant to flexing easily, forming frames 411,412 of, for example, a relatively rigid metal such as steel.
[020] A link 430 rotates the first segment section 410 to the main section 401 and includes an upper bar 431 and a lower bar 432 which are both coupled to the main frame 402 and the first segment frame 411. As shown, the upper bar 431 can swivel coupling to the upper main bar 404 in an upper main pivot 406 and the upper bar of the first segment 412 in an upper pivot of the first segment 414 and the lower bar 432 can swivelly couple the lower main bar 405 to a lower main pivot 407 and the lower bar of the first segment 413 to a first lower pivot of segment 415. Likewise, a second connection 440 can pivotably connect the first section of segment 410 to the second section of segment 430 and include a second upper bar 441 and a second lower bar 442. As shown, the second upper bar 441 can swivelly attach to the
Petition 870180073508, of 08/21/2018, p. 22/35
11/13 upper bar of the first segment 412 in another upper pivot of the first segment 416 and the upper bar of the second segment 422 to an upper pivot of the second of segment 424 and the second lower bar 442 can swivel to the lower bar of the first segment 413 in another lower pivot of the first segment 417 and the second lower bar 442 to a lower pivot of the second segment 425. It should be noted that additional segment sections can be added, if desired, and have constructions similar to the first and second sections segments 410, 420 described in this document.
[021] To control the rotation behavior of the first segment section 410 in an exemplary embodiment formed in accordance with the present invention, an actuator 450 can be coupled to the upper bar 431, the lower bar 432 and / or the first section of segment 410. In some exemplary embodiments formed in accordance with the present invention, actuator 450 can couple upper bar 431 to lower bar 432, as shown or, alternatively, actuator 450 can connect to other parts of platform 400 such as the main section 401 or the first section of segment 411. In another exemplary embodiment formed in accordance with the present invention, actuator 450 can be part of a set of calibration wheels (not shown) that supports the weight of the first section of segment 410 and allows that the first section of segment 410 follows the ground. Actuator 450 can be, for example, a selectively activated cylinder that can cause linear up and down movement of the upper main bar 403 and lower main bar 404, as well as the upper bar of the first segment 412 and lower bar of the first segment 413 Additionally, actuator 450 can be selectively activated to control the rotational behavior of the first segment section 410 in relation to the main section 401. Likewise, in some exemplary embodiments formed according to
Petition 870180073508, of 08/21/2018, p. 23/35
12/13 of the present invention, a second actuator 460 can be coupled to the second upper bar 441, the second lower bar 442 and / or the second segment section 430; the second actuator 460 can couple the second upper bar 441 to the second lower bar 442, as shown, to other parts of the platform 400 or be a part of a set of calibration wheels (not shown), similar to the previously described actuator 450. Having if the platform 400 is separated in the main section 401 with the segment sections 410 and 420, the ground tracking of the cutter bar 403 can be improved due to the segment sections 410, 420 coupled to the main section 401 being independently rotatable, in relative to the main section 401 and to each other and capable of floating on the ground as the vehicle 100 travels through a field. The actuators 450, 460, therefore, can act to help control the floating behavior of the section (or sections) 410, 420 to help the platform 400 follow the ground that pushes or pulls a respectively connected element and causes a corresponding change in the following behavior of the section (or sections) of segment 410, 420.
[022] As can be seen, the upper bar 431 of the first link 430 can define a geometric axis of the upper bar UA2 and the lower bar 432 of the first link 430 can define a geometric axis of the lower bar LA2 which is parallel to the geometric axis of top bar UA2. Likewise, the second upper link 441 of the second link 440 can define a second upper link geometry UA3 and the second lower link 442 of the second link 440 can define a second lower link geometry LA3 which is parallel to the second geometric axis UA3 top bar. In an exemplary embodiment, the upper bar geometric axis UA2 and the lower bar geometric axis LA2 are not parallel to the second upper bar geometric axis UA3 and the second lower bar geometric axis LA3, which may be a result of platform 400 that if

13/13 travels on uneven terrain or an intentional relative slope.
[023] These and other advantages of the present invention will be evident to those skilled in the art from the previous specification. Consequently, it is to be recognized by persons skilled in the art that changes or modifications can be made to the above described achievements without departing from the general inventive concepts of the invention. It is to be understood that this invention is not limited to the particular embodiments described in this document, but is intended to include all changes and modifications that are within the scope and spirit of the invention.
