    BACKGROUND
    [001] The present application relates, in general, to corn platform assemblies for use with agricultural harvesters. In particular, the present application relates to an improved corn platform assembly that includes a peeler plate control system.
    [002] Agricultural combines that harvest corn are provided with platforms that have dividers, also known generally as mouthpieces, to direct the rows of corn stalks to row units that include cob separation chambers which are defined by de-earing plates or removal plates that position the corn cobs for separation from the stalks. The corn cobs are then passed to an auger for transporting the corn to an agricultural combine feeder housing. Harvested corn is then processed into the inner chambers of the combine for further processing.
    [003] Conventional corn header mounts use an oscillating shaft to control the separation of the despicker plates (also referred to as the span). Such peeler plate separation designs have a swing arm mounted vertically to the row unit and a control link below the row unit to move the peeler plates. As a result, adjusting the peeler plate opening from row to row can be difficult, abrupt and imprecise. The mechanical tolerances that are built into such a peeler plate separation project in order to improve the ease of movement of the peeler plate also lead to clearances that affect the operator's ability to properly set the peeler plates. Poorly adjusted or improperly set desear plates cause grain loss, ear damage and economic losses. Such designs are also bulky, heavy and take up valuable space under the corn header row unit. Additionally, such designs can generate excess debris that can lead to garbage accumulation under the corn platform assembly that effects the overall operation and efficiency of the platform. In addition, conventional oscillating shaft control systems typically control one of two single-row unit de-stalker plates which can lead to the de-stalker plate opening (or span) not being aligned with the center of the tang rollers. row unit. The swingarm control is typically mounted on the side of the row unit frame and limits, due to space constraints, the minimum row spacing of row units. BRIEF SUMMARY
    [004] According to a first aspect, the present application provides a row unit for a platform of an agricultural combine that includes a longitudinally extended first take-off plate and a longitudinally extended second take-off plate, each mounted on a frame and which define a gap between the first stripping plate and the second stripping plate. The row unit additionally includes a span adjustment mechanism to adjust a span size. The span adjustment mechanism includes a first link assembly and a second link assembly. The first link assembly has a first elongate link which extends substantially parallel to the longitudinally extended first take-off plate and a first link mechanism which connects the first elongate link with the longitudinally extended first take-off plate. The second link assembly has an elongated second link that extends substantially parallel to the second longitudinally extended peel plate and a second link mechanism that connects the second elongate link to the second longitudinally extended peel plate. The row unit additionally includes a control arm operatively connected to both the first and second link assemblies to move the first and second link assemblies between the first and second positions.
    [005] According to a second aspect, the present application provides a row unit for a platform of an agricultural harvester that includes a frame having an upper side and a lower side, a stripper plate mounted on the frame, a crosslink and an adjustment mechanism positioned on the upper side of the frame and adjacent to the side side of the de-stalker plate to move the de-stalker plate. The adjustment mechanism includes a link assembly that has an elongated link that extends adjacent to the peeler plate, a primary connection mechanism that connects the elongated link to the peeler plate, and a secondary connection mechanism that connects the link. elongated to the peeler plate. The crosslink is operatively connected to the elongated link to move the peeler plate between a first position and a second position.
    [006] According to a further aspect, the present application provides a system for adjusting or moving the de-stalker plates on a corn platform by means of the parallel movement of the connecting link and the desearer plate. According to this aspect, a link is activated and linked from row to row by a cross-linking control arm that is usually perpendicular to each of the peeler plates. In accordance with this aspect, the peeler plate adjustment mechanism is positioned on the upper side of the frame and the conventional swingarm is eliminated and replaced by light weight control links. With such a design there is no need to position components below the row unit, thus all components can be serviced from the top side of the frame without the need to carry out maintenance work under the platform.
    [007] The corn platform despreader plates are connected to a control arm by a pair of parallel elongated links that define two sides of a parallelogram. The elongated links are designed so that the parallelogram is contracted or expanded as the peeler plate moves tighter or wider. When the parallelogram is contracted so that the elongated links are close together, the stripper plate opens to allow larger stems to pass through. When the parallelogram is expanded so that the elongated links are further apart, the peeler plates move closer together to allow the row unit to work effectively with smaller stems. The left peeler plate can be linked to the right peeler plate by the control arm. This same control arm can be used to connect row unit to row unit adjustment mechanisms. The two ends of the descapper plate through which corn enters the platform define a wedge opening. The wedge opening of the peeler plates can be set fixed in the design or the design can be produced to allow the front of the peeler plates to have a different width than the back.
    [008] According to other aspects, the present application additionally provides peeler plates connected to a control arm by a pair of long parallel links that define two sides of a parallelogram. Parallel linkage can be produced with a rotating cam, triangular linkage arms, L linkage arms or similar. The shape of the control arm and parallel links can be any shape, for example, flat, oval, round, square or L shape. or maximum available aperture.

    [023] Now with reference to the drawings, in which aspects of the present application are shown, Figure 1 illustrates the assembly of corn header 12 according to an aspect of the present application, as applied to the agricultural combine 10. The assembly Corn Header 12 is an improvement to current conventional corn header mounts for agricultural combines by incorporating a desher plate control system that can allow more effective adjustment of the peeler plate opening to respond to variations in corn stalk width through a simple, compact and substantially flat design. The corn header assembly 12 is shown as operatively connected to the agricultural combine 10 for harvesting corn and feeding the corn to the feeder housing 16 for receiving crop residue, cutting, thinning and propulsion of the residue. back and out of the combine 10 while retaining valuable grain and corn cobs. Such feeder housings and harvesting operations are known in the art and a detailed description of their structure, function and operation is not necessary for a full understanding of that particular aspect of the present disclosure. However, typical corn platforms applicable to the present disclosure are disclosed in U.S. Patent Nos. 3,808,783 and 3,759,021, of which the entire disclosure is incorporated herein by reference for all purposes.
    [024] Corn deck assembly 12 includes deck frame 14 for mounting on a front end of agricultural combine 10, a conveyor 20 (like an auger) that extends lengthwise through deck frame 14 for transporting the crop material to a combine harvester feed location or feeder housing 16 through channel 18 and a plurality of row units 22 extending forward from the platform frame 14. The corn platform assembly 12 further includes a plurality of dividers 24 extending forward from the platform frame 14. Such dividers 24 are known in the art and a detailed description of their structure, function and operation is not necessary for a full understanding of that aspect. particular of the present disclosure.
    [025] As shown in Figure 2 which is a perspective view of a single row unit 22, in accordance with an aspect of the present application, there are shown stripping plates or stripping plates 36a, 36b defining a span 28 therebetween. which is open towards the front end of the row unit 10. The shield 34 defines the closed end region of the span 28 and is positioned at an end of the row unit 22 closest to the agricultural combine 10, i.e. a proximal end. of the row unit.
    [026] Figures 3 and 4 show a perspective view and a side perspective view of the row unit 22 without a collection chain assembly. Row unit 22 includes frame 26 which forms two row unit arms 30a, 30b, shield 34 and two peel plates 36a, 36b defining span 28. The frame has an upper side and a lower side. Figure 3 shows gearbox 38 positioned in a lower portion of frame 26. Gearbox 38 generates power to drive pick-up chains 32a, 32b of row unit 22.
    [027] In other words, the row unit 22 includes a longitudinally extended first peel plate 36a and a longitudinally extended second peel plate 36b, each mounted to a frame 26 and each having opposing peeling edges defining the gap 28 between the first take-off plate 36a and the second take-off plate 36b. In accordance with an aspect of the present application, a first destalker plate may be positioned at an angle other than parallel to the second destalker plate. In such an aspect, a relative angle between the first and second stripper plates can be fixed in the row unit assembly or it can be adjustable by an operator. In accordance with such an aspect, the ends of the first and second descapper plates define a wedge opening through which corn enters the row unit. The wedge opening can be defined fixed in the design or the row unit design can allow the front of the desher plates (which is the end of the desher plates through which the corn enters the row unit) to be in a width different from the width of the back of the stripper plate, for example, wider towards the front and narrower towards the rear.
    [028] As shown in Figure 5, row unit 22 additionally includes a span adjustment mechanism 40 to adjust a span size 28. Span adjustment mechanism 40 includes first link assembly 42a having a first link assembly 40a. elongate link 46a extending substantially parallel to first longitudinally extending peel plate 36a and a first connecting mechanism 44a connecting first elongate link 46a to first longitudinally extending peel plate 36a. The span adjustment mechanism 40 also includes second link assembly 42b which has a second elongate link 46b that extends substantially parallel to second longitudinally extended peel plate 36b and a second link mechanism 44b that connects second elongate link 46b to the second longitudinally extended stripping plate 36b.
    [029] Referring again to Figure 3, span adjustment mechanism 40 is positioned above gearbox 38. Additionally, span adjustment mechanism 40 is positioned above row unit arms on an upper side of the frame to allow for ease of maintenance of row unit 22. Additionally, the link assemblies and link mechanisms are adjacent to the side of the peeler plates, so that all components of the span adjustment mechanism lie substantially within a plane defined by the stripping plates.
    [030] The row unit 22 also includes a control or crosslink arm 50 operatively connected to the first and second linkage assemblies 42a and 42b to move the first and second linkage assemblies 42a and 42b between the first. and the second position. In accordance with certain aspects of the present application, the elongated links are positioned substantially transverse or perpendicular to the crosslink.
    [031] The first and second connection assemblies 42a, 42b include, respectively, the first and second connection mechanisms 44a, 44b. Each of the first and second linkage mechanisms 44a, 44b can be a toggle lever, a swivel cam, a link assembly, a pivot mechanism, or the like. Figures 6A and 6B illustrate examples of connection mechanisms suitable for use as first and second connection mechanisms 44a, 44b.
    [032] The connecting mechanism 44a is configured and shaped as best shown in Figure 6A as an elongated toggle lever. The connecting mechanism 44a is formed from two joining flat mirror elements, each of which is generally elongated in shape with a central passage for pivotal connection to the frame row unit. A tail or posterior end of the connection mechanism extends further distally from the central passage than a front end of the connection mechanism. Each aft end of the two flat elements is staggered to form a receiving gap to accommodate the shape of the control arm 50 and includes a passageway for pivotal connection thereto. In this way, when the two flat mirrored elements come together, the trailing ends create a double end for receiving and mounting on the control arm. The front end of the connecting mechanism is generally arrowhead shaped with a side side that extends outward from the central passage. Pivot connection passages encircle the center passage every approximately ninety degrees. As best shown in Figure 5, the anterior most passage is pivotally connected to the detacher plate 36a, while the most lateral passage connects to the first elongate link 46a over the proximal end of the first elongate link. As such, the connection mechanism 44a is pivotally connected to the detacher plate at a position more forward and more distal to the control arm than the point at which the first elongated connection is pivotally connected to the connection mechanism. . Consequently, this causes the peeler plate 36a to move inward when the control arm moves to the left side of the platform.
    [033] The connecting mechanism 44b is configured and shaped as best shown in Figure 6B as an elongated toggle lever. In one aspect, the connection mechanism is configured substantially as a mirror image of the connection mechanism 44a. The connection mechanism 44b is formed from two adjoining flat mirror elements, each of which is generally elongated in shape with a central passageway for pivotal connection to the frame row unit. A tail or rear end of the connection mechanism extends further distally from the center passage than a front end of the connection mechanism. Each rear end of the flat elements is staggered to form a receiving gap to accommodate the shape of the control arm 50 and includes a passageway for pivotal connection thereto. In this way, when the two flat mirrored elements come together, the trailing ends create a double end for receiving and mounting on the control arm. The front end of the connecting mechanism is generally triangular in shape with one of its side sides extending further outward than its opposite side side from the central passage. The connection mechanism 44b includes a passage over its front most end, a passage over its wider side end, and a passage between the center passage and the rear end. Each of these passages are spaced approximately ninety degrees apart. As best shown in Figure 5, the passage between the central passage and the rear end is pivotally connected to the stripper plate 36b, while the lateral side passage connects to the second elongated connection 46b over the proximal end of the elongated second link. As such, the connection mechanism 44b is pivotally connected to the second elongated connection at a position more forward or more distal to the control arm than the point at which the peeler plate is pivotally connected to the connection mechanism. . Consequently, this causes the peeler plate 36b to move inward when the control arm moves to the left side of the platform.
    [034] The secondary connection mechanisms 48a, 48b are configured as shown in Figures 6C and 6D. Each of these secondary connection mechanisms includes a central passage to connect to the row unit frame and a pair of spaced passages to connect to the elongate link and the detacher plate. As shown in Figure 5, the secondary link mechanism 48a has a detacher plate pivotally attached to a point more forward or distal to the control arm than its pivotal attachment to the first elongated link 46a. Additionally, the secondary link mechanism 48b has the second elongated link 46b pivotally attached at a point more forward or distal to the control arm than its pivotal attachment to the detacher plate 36b. Consequently, this configuration of the secondary connecting mechanisms in combination with the connecting mechanisms 44a, 44b causes the despicker plates to move inwards when the control arm then moves to the left side of the platform. Of course, the aforementioned connection mechanisms can alternatively be configured so that the despicker plates move inward when the control arm moves to the right side of the platform.
    [035] Referring again to Figures 3 and 5, in certain aspects of the present application, each of the first and second connection mechanisms 44a, 44b is a pivot mechanism connected to respective elongated links and take-off plates, and connected pivotally to the frame. It can be noted that the manner and configuration in which the connecting mechanisms 44a, 44b are connected to the respective peel plates 46a, 46b determines the response of each of the peel plates 46a, 46b to a rotation of the connecting mechanisms 44a , 44b.
    [036] By configuring each of the first and second connection mechanisms 44a, 44b in this way in relation to the peeler plates, when viewed as shown in Figure 5, a clockwise rotation of the first connection mechanism 44a causes the peel plate 36a to move medially relative to the center of the row unit 22. Similarly, a clockwise rotation of the second connecting mechanism 44b causes the peel plate 36b to also move medially with respect to the center of the 22-row unit.
    [037] In other words, the first and second connecting mechanisms 44a, 44b are each connected to the peel plates 36a, 36b so that the first and second peel plates 36a, 36b respond by movement. -to parallel, respectively, to a movement of control arm 50. This effect is achieved due to the fact that movement of control arm 50 in a particular direction causes a similar rotation of each of the first and second connection mechanisms 44a, 44b. This rotation of each of the first and second connection mechanisms in the same direction (which is clockwise or counterclockwise), in turn, causes the first and second stripping plates to move together ( medially with respect to frame 26) or separated (laterally with respect to frame 26). Thus, for a particular movement of the control arm 50, the first and second connection mechanisms 44a, 44b will rotate or pivot in the same direction that causes the first and second removal plates 36a, 36b to move. , each laterally or medially with respect to the frame 26. The effect of the movement of the peel plates 36a and 36b acts to increase or decrease the size of the span 28.
    [038] The span adjustment mechanism 40 is responsive to movement of the control arm 50 in a first direction to move the first and second linkage assemblies 42a, 42b to a first position, and in a second direction to move the first and second connecting assemblies 42a, 42b for a second position. The first position can correspond to a narrow span position, while the second position can correspond to a wide span position. That is, the size of span 28 is larger in the second position than the size of span 28 in the first position.
    [039] In accordance with another aspect of the present application, the first and second connection assemblies 42a, 42b include a first secondary connection mechanism 48a and a second secondary connection mechanism 48b. Figures 6C and 6D illustrate toggle levers suitable for use as the first and second secondary connecting mechanisms 48a, 48b. However, toggle levers of other configurations suitable in design for the purpose for which it is intended are also applicable.
    [040] In certain aspects of the present application, each of the first and second elongated links 46a, 46b moves in parallel motion with the first and second longitudinally extending peel plates 36a, 36b, respectively. This is achieved by setting the spacing between the elongated link and the peeler plate via the link mechanism, eg link mechanism 44a, 48a, to be equal over their respective range of motion.
    [041] A span adjustment mechanism in accordance with an aspect of the present order is substantially flat when fully assembled. The linkage assemblies and linkage mechanisms of the span adjustment mechanism have generally flat profiles, as shown, for example, in Figures 4 and 5. In addition, the linkage assemblies and linkage mechanisms are positioned so that they are adjacent to a side of the peeler plates. In this configuration, the linkage assemblies and linkage mechanism are all positioned above an upper surface of the row unit frame. As such, the span adjustment mechanism of the present application allows the entire mechanism to lie substantially within or adjacent to a plane defined by the destalker plate (or destalker plates), thus reducing the amount of space required for installation in row units and to facilitate spacing of row units in very narrow spacings.
    [042] In the operation during harvesting, the rows of plants to be harvested are aligned and directed to the gap 28 formed by the removal plates 36a, 36b. As the combine harvester 10 moves through a row of crops, the plants are guided towards gap 28, where the corn cobs are then removed from the stalks between the take-off plates 36a, 36b. After separating the corn cobs, the stalks fall under the harvester 10 and the corn cobs are moved back and onto the platform frame 14 by the action of collection chains 32a, 32b. Conveyor 20 then moves corn cobs to the center of platform frame 14 so that they are fed to feeder housing 16 through channel 18. The configuration and operation of such input arrangements are typical of agricultural harvesters .
    [043] Additionally, the span adjustment mechanism 40 allows each of the peel plates 36a, 36b to move in parallel motion between a first position and a second position. The span size 28 when the destalker plates 36a, 36b are in the first position is suitable for certain stem widths, while the span size 28 when the destalker plates 36a, 36b are in the second position is suitable for certain other stem widths . The size of the span 28 generated by the span adjustment mechanism 40 is controlled by the movement of the control arm 50. The control arm 50 is operatively connected to a drive or other mechanism for changing its position, for example, a motor (not shown) which is changed manually and/or remotely by an operator.
    [044] The present application advantageously provides span adjustment mechanism 40 positioned above frame 26 and/or on an upper side of frame 26 as opposed to below frame 26, as it is positioned in conventional unit designs of row. Furthermore, as the span adjustment mechanism 40 is positioned on the upper side of the frame 26, all components of the span adjustment mechanism may be useful from an upper side of the platform and/or row unit.
    [045] In summary, the row unit 22 has a peeler plate connected to a control arm by a pair of parallel links (eg, link assemblies) that together define a parallelogram. Parallel links are designed so that the parallelogram is contracted or expanded as the peeler plate moves tighter or wider and the area occupied by the parallelogram increases or decreases. In operation, when the parallel-gram is shrunk so that the elongated legs are close together, the stalk opening opens to allow larger stems to pass through. When the parallelogram is expanded so that the elongated links are further apart, the despicker plates move closer together to work with smaller stems. In this way, the parallelogram is distinguished by an area that is responsive to the movement of the reticulation.
    [046] The first despicker plate is linked to the second despicker plate through the control arm mechanism. This same control arm can extend across the entire width of the platform connecting link assemblies from all of the plurality of row units. The wedge opening of the peeler plates can be defined fixed in the design or the design can be produced to allow the gap defined by the front of the peeler plates to have a different width than the gap defined by the rear of the peeler plates.
    [047] Systems according to aspects of the present application provide several design options. The parallel linkages of the span adjustment mechanism can be produced implanted in various ways, for example, a rotating cam, a triangular linkage arm, an L linkage arm, a pivot mechanism or the like. Additionally, the shape of the control arm and parallel links can be flat, oval, round, square or L-shape. Additionally, the gap between the opening of the peeler plates can be designed to allow 100% closing and/or maximum available opening .
    [048] Referring now to Figures 7 to 10, according to another aspect, the present application provides a row unit 122 for a platform of an agricultural harvester having a longitudinally extending first take-off plate 136a and a second longitudinally extended stripping plate 136b defining a gap 128 between the first stripping plate 136a and the second stripping plate 136b. The row unit additionally includes a span adjustment mechanism 140 to adjust a span size 128, and a control arm similar to control arm 50 described above. The span adjustment mechanism 140 includes a first link assembly 142a that has a first elongate link 146a that extends substantially parallel to the first longitudinally extending peel plate 136a and a first link mechanism 144a that connects the first elongate link 146a to the first longitudinally extended stripping plate 136a. The span adjustment mechanism 140 also includes a second link assembly 142b which has a second elongate link 146b that extends substantially parallel to the second longitudinally extended peel plate 136b and a second link mechanism 144b that connects the second. elongated connection 146b to second longitudinally extended peel plate 136b. The span adjustment mechanism 140 additionally includes a first secondary connection mechanism 148a and a second secondary connection mechanism 148b which respectively connect the first elongate link 146a to the first longitudinally extended peel plate 136a and the second elongate link 146b to the longitudinally extended stripping plate 136b.
    [049] The control arm is operatively connected to the first and second link assemblies 142a and 142b to move the first and second link assemblies 142a and 142b between the first and second positions in a similar manner to the control arm. control 50 described above.
    [050] As shown in Figure 7, the first take-off plate 136a and the second take-off plate 136b are first positioned so that the gap 128 defines a first width W1. In Figure 8, first stripping plate 136a and second stripping plate 136b are positioned secondly so that span 128 defines a second width W2 that is narrower than the first width. Consequently, the gap is greater in the second position than in the first position.
    [051] The row unit 122 also includes a pair of shank rollers 137a, 137b mounted on the frame, which rotate to pull the stalks down through the gap defined by the take-off plates. In accordance with the present application, the first and second link assemblies move simultaneously between the first and second positions to keep the span centered on the tenon rollers.
    [052] Figure 9 provides an enlarged detail view of a toggle lever used as a secondary connection mechanism. Figure 10 shows an enlarged detail view of a toggle lever used as a primary or tertiary connecting mechanism. The link mechanism 144a is connected to the elongate link 146a but is not directly connected to the control arm 150. In that regard, an additional tertiary toggle lever 148c connects the elongate link 146a of the first link assembly to the control arm 150 so that the control arm is operatively connected to the elongate link 146a to move the peeler plate 136a between a first position and a second position. The connection mechanism 144b and the second connection assembly are similarly configured as described for the connection mechanism 144a and the first connection assembly. Additionally, the second link assembly 142b may include a tertiary link mechanism similar to the tertiary link mechanism 148c.
    [053] Figure 11 illustrates yet another aspect of a row unit 222 according to the present application. Row unit 222 is configured similarly to row unit 122 described above and includes a longitudinally extending first take-off plate 236a, a longitudinally extended second take-off plate 236b, a gap 228 between the first and second. removal plates defining the span, a span adjustment mechanism 240 similar to span adjustment mechanism 140 described above, and a control arm 250. Span adjustment mechanism 240 includes a first link assembly 242a having a first elongated link 246a that extends substantially parallel to the first longitudinally extended peel plate. Span adjustment mechanism 240 also includes a first connection mechanism 244a, a first secondary connection mechanism 248a, and a tertiary connection mechanism 248c, each of which connects the elongated first connection to the longitudinally extended first removal plate.
