    DOUBLE ROW PLANTER WITH TANDEM ACTIVATED SEED METERS The present invention relates to a double row planter with tandem driven seed meters on a pair of row units in each row segment of a double row planter. A tandem driven system drives seed gauges in a tandem manner, which can include a single drive assembly that simultaneously spins a pair of seed disks on the pair of seed gauges in each row segment. An indexing system allows for rapid change in a relative or angular rotating amount of seed discs within the pair of 11 seed meters in the pair of row units of each row segment to adjust the spacing longitudinally between the distribution sites of seeds from seed discs in planted row segments of a double planted row. Adjustments can be made to the disc hubs, between the shaft segments that connect the seed discs, or with various mounting sets to retain the seed discs.

    TECHNICAL FIELD
    [001] The present invention relates in general to row crop planters. Specifically, this invention relates to a double row planter with TANDEM driven seed meters. BACKGROUND OF THE INVENTION
    [002] Modern agricultural practices are seriously trying to increase agricultural production. Yields can be increased by increasing plant populations. Efforts have been made to increase plant populations by planting row crops with narrower row spacing, allowing the largest number of rows to be planted, which may require harvesting with special equipment configured to harvest narrow rows, such as narrow row collectors for harvesting implements. Double row planters have been developed that plant seeds as a pair of row segments that are closely spaced. Each pair of row segments is spaced from adjacent pairs of row segments in conventional row widths, allowing conventional collectors to be used in harvesting implements. This is typically done by assembling a pair of row units with a pair of corresponding seed gauges in each row segment, with the seed gauges staggered longitudinally in a ratio of one seed gauge forward and one seed gauge backward. Seed meters for double row planters are typically also made from components that are narrower than non-double row planters, with each seed meter mounted separately on the toolbars of double row planters. This longitudinal scaling and relatively narrow component configuration of the paired row units provides the mounting space needed to separately assemble the paired row units and their corresponding pair of seed meter drive systems from a planter tool bar. double row. SUMMARY OF THE INVENTION
    [003] The present invention is directed to one with TANDEM driven seed meters in a pair of row units in each row segment of a double row planter. A TANDEM driven system can drive seed meters in a TANDEM way with a single transmission set that simultaneously rotates a pair of seed disks on a pair of seed meters in each respective row unit. This allows the TANDEM-driven system to take up relatively little space on the double-row planter, providing enough space so that the pair of row units in each segment can have life-size seed gauges arranged side by side adjacent in cross alignment between without the additional weight of a separate drive system for each seed meter. An indexing system is provided to allow rapid change in a relative rotational or angular indexing amount of seed discs within the pair of seed meters in the pair of row units for each row segment to control longitudinal spacing between locations of the seeds of the seed disks. This allows the seed discs to rotate at an identical rate of rotation while providing adjustability of distribution characteristics to accommodate the planting of different seed types in different sessions with seed discs that have different seed bag spaces in the seed discs. seed, to provide consistent spacing after appearance.
    [004] According to another aspect of the invention, the pair of row units in each row segment of the double row planter can be supported from a single collector support supported by a tool bar of the double row planter. With the pair of row units spaced close enough together to distribute seeds in the first and second row segments planted that can be harvested with a single row segment from a standard width harvester, for example, with the first and second segments of row planted being spaced transversely between each other between around 12.7 centimeters and 25.4 centimeters, as well as between approximately 17.7 centimeters and 20.32 centimeters.
    [005] According to another aspect of the invention, a double row planter is provided with a chassis that can be towed behind a tractor through an agricultural field for planting seeds in the field during a planting session. Multiple row segments are supported by the chassis. Each of the multiple row segments includes a first seed meter supported in the row segment for single seeds for individual distribution in the field. The seeds are released from the first seed meter in a first segment of the planted row, with the seeds aligned longitudinally and spaced apart. A second seed meter is supported in the row segment for single seeds for individual distribution in the field in a second planted row segment. The seeds are released from the second seed meter in a second planted row segment, with the seeds from the second seed meter aligned longitudinally and spaced apart and staggered with respect to the first planted row segment. A system operated in TANDEM with a transmission set distributes energy to the first of the second seed meters to singularize and distribute seeds in the first and second row segments planted, respectively.
    [006] According to another aspect of the invention, the transmission assembly may include an axis assembly with a first axis segment and a second axis segment engaging and rotating in unison with the first axis segment. The first axis segment can distribute energy to the first seed meter and the second axis segment can distribute energy to the second seed meter. The first seed meter may also include a first seed disk rotated by the first axis segment of the axis assembly within the first meter to transport individual seeds through the first seed meter for individual distribution in the field in the first planted row segment. The second seed meter may also include a second seed disk rotated by the second axis segment of the axis assembly within the second meter to transport individual seeds through the second seed meter for individual distribution in the field in the second planted row segment.
    [007] According to another aspect of the invention, an indexing system is arranged with respect to the axis assembly to selectively adjust an angular index position of the seed discs of the first and second seed meters with respect to each other. The indexing system may include an indexing disk hub system that has a disk hub configured to adjust an angular index position of the disk hub with respect to the axis assembly to adjust accordingly the angular index position of the disks of seed from the first and second seed meters with respect to each other. The indexing disc hub system may include an axle hub mounted on and rotating in unison with the axle assembly and an adjustable disc hub mounted on the axle assembly to rotate in unison with the axle hub. The disc hub can be movable from the first angular position with respect to the axle hub to the second angular position with respect to the axle hub. This allows for the adjustment of the relative positions of the seed bags on the first and second seed disks with respect to each other while rotating in unison during the planting session to change the seed spacing characteristics in the first row segment planted for the seeds in the second segment of the planted row. The disc hub may engage a first end surface of the axle hub, and the indexing system may also include a clamping ring that engages a second end surface of the axle hub. The clamping ring and the disc hub can be configured to loosen and tighten to loosen and tighten the axle hub between them. This respectively unlocks the indexing disc hub system allowing adjustment of the angular index position and locks the indexing disc hub system to lock the rotating disc hub and axle assembly in unison with each other. The axle hub may include slots that extend through the thickness of the axle hub. The slots can define perimeters that extend longitudinally through parts of the first and second end surfaces of the axle hub. Fasteners can extend through slots in the axle hub, interconnecting the disc carrier and clamping ring. The fasteners can be movable in the length of the slots to slide along the slit to adjust the angular index position of the disc hub with respect to the shaft assembly.
    [008] According to another aspect of the invention, the indexing system may include an indexing hub hub system that has a first hub hub connected to the first axis segment of the axis assembly and a second axis hub connected to the second axis segment of the axis assembly. The indexing axis cube system can be configured to adjust an angular index position of the first and second axis cubes with respect to each other to correspondingly adjust the angular index position of the seed discs of the first and second seed meters. seed with respect for each other. The indexing hub cube system may also include a coupling assembly that selectively locks the first and second axis hubs in rotation in unison with each other to correspondingly lock the first and second hollow segments of the shaft assembly to rotate in unison with each other. The coupling assembly of the indexing axle hub system may include a pin and multiple holes in the first and second axle hubs. Each of the multiple holes can be configured to receive the pin to establish a respective predetermined angular index position of the first and second axis hubs with respect to each other and a corresponding predetermined angular index position of the seed discs of the first and second seed meters. seed with respect to each other. One of the first and second axle hubs can be axially movable with respect to the other of the first and second axle hubs to adjust an angular index position of the first and second axle hubs with respect to each other by removing the pin from a first of the multiple holes and inserting the pin in one second of the multiple holes.
    [009] According to another aspect of the invention, the indexing system can include a seed disc system with multiple index position that includes an axle hub mounted on and rotating in unison with the axle assembly. The axle hub may include an axle body with ears / terminals extending from the hub body. At least one of the first and second seed disks includes a first set of mounting holes and a second set of mounting holes configured to receive the ears of the shaft hub to arrange at least one of the first and second seed disks in a first angular index position and a second angular index position, respectively. Each of the first and second seed discs can have a first set of mounting holes as each of the mounting holes of the first set of mounting holes having a first perimeter shape and a second set of mounting holes with each of the mounting holes of the second set of mounting holes having a second shape of perimeter. The multiple index position seed disk system may include a first axle hub mounted on the first axle segment of the axle assembly with the first axle hub including a hub body with ears extending from the hub buckle and which they have a first shape of perimeter configured to receive the mounting holes of the first hole mounting set to mount a first seed disk at an angular index position with respect to the axis assembly. A second axle hub is mounted on the second axle segment of the axle assembly. The second axle hub has an axle body with ears extending from it, with the ears having a second shape of perimeter configured to receive the mounting holes of the second set of mounting holes to mount a second seed disk on a second angular index position with respect to the axis assembly. In this way, the different types of the different mounting hole sets ensure that the disc (s) are mounted in the correct angular index position for the specific seed meter (s).
    [010] According to another aspect of the invention, in each row segment, the seed meters can be mirror images of each other. Each of the first and second seed meters can include a seed compartment and an air pressure compartment. The air pressure seed compartments of the first and second seed meters are mirrored with respect to each other around a reflection line that extends in a longitudinal direction between the first and second seed meters.
    [011] According to another aspect of the invention, the TANDEM driven system includes a transmission set that distributes energy to a single location on an axis set. The spindle assembly can extend transversely between the first and second seed disks along a common geometric axis of rotation of the first and second seed disks and can distribute energy from the transmission assembly to simultaneously rotate the first and second seed disks. seed. This can allow the seed meters to be parallel to each other in transverse alignment, side by side, relationship within the row segments of the double row planter.
    [012] According to another aspect of the invention, the indexing system is configured to selectively disengage the first and second axis segments from the axis assembly to allow relative rotation of the first and second axis segments of the axis assembly during a procedure indexing adjustment. Selective disengagement by means of the indexing system also facilitates the removal of any of the meters in the need to remove the other. The indexing system is also configured to selectively engage and lock the first and second axis segments of the axis assembly for rotation in unison with each other with the first and second seed discs angularly indexed with respect to each other at different times of the year. duration of the indexing adjustment procedure.

    [028] With reference to the drawings and specifically to the simplified schematic representations of Figures 1 and 2, a double row planter 5 is illustrated with a TANDEM 7 driven system to drive both seed meters 9 into a pair of 11A row units , 11B in each row segment 13 of the planter 5 while facilitating angular coordination of the seed meter components to optimize the consistency of the placement of the seed in double row within the planted row segments of the staggered planted row 12A, 12B of single seeds in a double row 12 distributed by row units 11A, 11B in each row segment 13, as explained in greater detail elsewhere in the context. Planter 5 can be or can include planter components available from Case IH, such as the EARLY RISER® series planters and / or double row planters such as the TWIN-ROW 4025A39S, 1225AFF, and 825A3PM models, also available from Case IH. Planter 5 is towed behind a tractor 15 and has a chassis 17 with a frame that includes a tool bar 19 that supports the multiple row segments 13, which are substantially identical. Each row segment 13 has a double row configuration with its respective pair of row units 11A, 11B connected to a single collector support 21 which is fixed to the tool bar 19 by means of a parallel connection system (not shown) that assembles each row segment 11 to the planter chassis 17. In each row segment 13, a pair of row units 11A, 11B, and the respective seed meters 9 are parallel to each other in a side-to-side relationship transversely aligned with each row unit 11A, 11B and its seed meter 9 spaced longitudinally from the tool bar 19 by the same distance. Each row unit 11A, 11B has ground engaging tools (not shown) that can include opening and closing mechanisms such as opening discs and closing discs, respectively, or other ground engaging tools to open and close a groove. Ground engaging tools may also include a metering wheel configured to adjust the depth of the groove by limiting the ground penetration of the groove opening mechanism of the ground engaging tools while creating a groove and a pressure wheel may be arranged. to roll over the closed furrow to firm the soil on the seed to also close the furrow and promote a favorable seed contact with the soil.
    [029] Still with reference to Figures 1 and 2, the seed is stored in a pile on planter 5 in a bulk seed storage system 23 that distributes the storage seed to row units 11A, 11B in each row segment 13. Referring now to figure 1, the seed storage system is shown as a seed pile storage system, with 25 pile filling tanks, which retain the seeds in a pile that will be pneumatically distributed from the filling tanks. stack 25 for row units 11A, 11B in each row segment 13. Referring now to Figure 2, the seed storage system is illustrated as a row stack storage system, with stack in a row, which they retain in a stack that will be fed by gravity to row units 11A, 11B in each row segment 13. Regardless of where the seeds are stored on planter 5 and as seeds are distributed to row units 11A, 11B in each row segment 13, seed meter 9 across all row units 11A, 11B is configured to single out and distribute individual seeds to the agricultural field to provide the segments of planted rows of planted row 12A, 12B of single seeds in each double row 12. The seeds distributed from the first row unit 11A are distributed in the field so that they are longitudinally aligned and spaced apart within the planted row segment 12A, with seed placement represented by dashed line circles in the planted row segment 12A. The seeds distributed from the first row unit 11B are deposited in the field so that they are longitudinally aligned and spaced apart within the planted row segment 12B, with the seed placements represented by dashed line circles in the planted row segment 12B . The seeds in the first and second row segments planted 12A, 12B are spaced transversely close enough to each other to be harvested with a single row segment from a standard width harvester. The first and second planted row segments 12A, 12B can be spaced transversely from each other between about 12.7 cm and 25.4 cm, such as between 17.7 cm and 20.32 cm. The seeds of the first planted row segment 12A are staggered longitudinally with respect to the seeds of the second planted row segment 12B. The adjacent double rows 12 of the adjacent row segments 13, which can be defined by longitudinally extending central lines extending between the first and the second planted row segments 12A, 12B, are spaced apart by distances that allow the double rows 12 are harvested with a single row segment from a standard width harvester, such as around 76.2 centimeters, 60.96 centimeters, or other standard row spacing.
    [030] Referring now to Figures 3 to 5, each seed meter 9 includes an internal seed disk 29 with seed bags 31 for harvesting and transporting individual seeds through the seed meter 9. The system driven in TANDEM 7 simultaneously rotates both seed disks 29 of the seed meter 9 in each row segment 13 through a seed reservoir inside the seed meter 9 to expose the seed bags 31 to the seeds in the seed reservoir to pick up the seeds in the bags seed 31. Although shown as extending axially through or between opposite surfaces of the seed disk 29, the seed bags 31 may, at least partially, extend to an outer circumferential surface of the seed disk 29. seeds 9 can be seed meters of the purely mechanical type 9 or they can be pneumatic seed meters 9, as illustrated. The pneumatic seed gauges 9 are operatively connected to an airflow system 33. The airflow system 33 can include a source of positive air pressure and / or a vacuum source to establish positive and / or vacuum pressures and corresponding air flows to operate the seed meters 9 in the row units 11A, 11B, such as within the air pressure compartments of the seed meter 9. The positive air pressure source and the vacuum sources can be pumps , known fans, blowers, and / or other known airflow system components. When the seed storage system 23 is configured with a central stack storage system (Figure 1), the air flow system 33 includes a seed transport air flow system that provides air flow that drags the seeds to move the seeds from the stack storage in the stack filling tanks 25 through the seed channels to the row units 11A, 11B, such as mini hoppers (not shown) that feed the seed meters 9. When the seed meters 9 are positive pressure pneumatic seed gauges 9, the airflow system 33 is configured to provide positive airflow and corresponding positive pressure within the seed gauges 9 to push the seeds into and retain the seeds in the bags. seed 31 from the seed disks 29 by positive pressure by introducing pressurized air into the seed meters 9. When the seed meters are pneumatic seed meters vacuum pressure systems 9, the air flow system 33 is configured to provide a vacuum air flow and corresponding negative pressure within the seed meters 9 to pull and secure the seeds in the seed bags 31 of the seed discs 29 by the vacuum pressure introduced in the seed meters 9, emptying the air out of the seed meters.
    [031] Referring now to Figures 3 to 5, each seed meter 9 has a housing 35 that includes interconnected covers, illustrated as a side seed cover 37 and a vacuum side cover 39 that collectively include the inside of the meter seed 9 and covers the seed disk 29. The side seed cover 37 is arranged parallel to and away from the seed disk 29. A seed reservoir 41 in which the seed reservoir collects is defined in the space between the side seed cover 37 and the seed disk 29. A seed inlet 43 extends through the side seed cover 37 to define a passageway as an entry point that allows seeds to enter the seed reservoir 41 from the seed storage system a bulk 23 (Figures 1 and 2). The side vacuum cover 29 is arranged parallel and spaced from the seed disk 29, on the other side of the seed disk instead of the side seed cover 37. An air pressure compartment shown as a vacuum compartment 45 in which the pressure vacuum is created in the housing 35 is defined in the space between the side vacuum cover 39 and the seed disk 29. A vacuum inlet 47 extends through the side vacuum cover 39 to define a passage through which air can flow out of housing 35 to establish vacuum pressure inside the seed meter 9. A seed tube 49 extends from an outlet 51 of the housing 35. The seed tube 49 receives seeds that are released from the seed disk 29 through the outlet 51 and directs the seed to the soil.
    [032] Referring now to Figures 3 and 4, the seed meters 9 are shown as mirror images of each other. The components and segments of the seed meters 9 of the row units 11A, 11B which include the seed disks 29, the seed reservoirs 41, and the vacuum compartments 45 are mirrored with respect to each other around a reflection line which extends in a longitudinal direction between the seed meters 9 of the row units 11A, 11B. Referring now to Figure 3, the seed reservoirs 41 of the seed meters 9 of the row units 11A, 11B are arranged facing each other. A shared seed inlet channel 53 defines a T-shaped or divided outlet body with a single tube inlet 55 that is operatively connected to the components of the bulk seed storage system 23 to direct the seed inlet channel 53 for the seed reservoirs 41 of the two seed meters 9 of the row units 11A, 11B in each row segment 13. Referring now to Figure 4, the vacuum compartments 45 of the seed meters 9 of the row units 11A, 11B are arranged facing each other. A shared vacuum inlet channel 57 defines a T-shaped or divided outlet body with a single channel inlet 59 that is operatively connected to the airflow system 33 to draw air out of and create a vacuum pressure within the compartments vacuum 45 from the two seed meters 9 of the row units 11A, 11B in each row segment 13.
    [033] Referring now to Figure 3, instead of mirror images of each, the seed meters 9 are shown arranged with the same general side-by-side layouts. Referring now to Figures 5 to 7, the vacuum inlet 47 is arranged at different locations on the side vacuum cover 39 on the two seed gauges 9 of the row units 11A, 11B. The vacuum inlet 47 of the seed meter 9 of the row unit 11A is arranged relatively lower in the seed meter 9, closer to the patent document 49 seed tube (Figure 6). The vacuum inlet 47 of the seed meter 9 of the row unit 11B is arranged relatively higher in the seed meter 9, further away from the seed tube 49 (Figure 7). The timed or misaligned relationship of row unit 11A of vacuum inlet 47 of seed meter 9 and row unit 11B of vacuum inlet 47 of seed meter 47 provides sufficient clearance for a vacuum line or hose (not shown) to extend between the seed meters 9 of the row units 11A, 11B.
    [034] Referring again to Figures 3 to 5, the seed disks 29 of each seed meter 9 are driven for rotation by the system driven in TANDEM 7 which includes an indexing system 61 that is configured to facilitate the coordination of indexing angle of the seed disks 29 to provide a desired predetermined seed distribution pattern of the planted row segments of the planted row 12A, 12B in each double row 12. After the seed disks 29 are indexed with respect to each other during the procedure indexing adjustment, explained in greater detail elsewhere in the context, the system powered by TANDEM 7 provides consistent distribution characteristics of seeds from row units 11A, 11B simultaneously distributing energy to and rotating discs 29 in unison with each other through a common energy flow path.
    [035] Still with respect to Figures 3 to 5, the system activated in TANDEM 7 includes a transmission set 63 that selectively distributes energy to the seed meters 9 of the row units 11A, 11B as controlled by a tractor control system and / or planter control system, which may include an industrial computer or, for example, a programmable logic computer (PLC), along with corresponding software and adequate memory to store such software and hardware including interconnecting conductors for power transmission and signal to control electronic, electromechanical and hydraulic components of the seed meters 9 and system activated in TANDEM 7 and other components of the planter 5. The transmission set 63 is illustrated with the mechanical chain drives 65 that distribute rotating drive energy of a rotation axis 67. The axis 67 is driven to rotate from the soil through the movement of the planter 5, such as a drive wheel of the traction drive type, gear wheel of engagement with the ground, or can be rotated by a motor such as an electric motor, a pneumatic motor or a hydraulic motor. The clutches 69 are controlled by the control system to engage and disengage to selectively transmit rotation of the shaft 67 for the movement of chains 71 that rotate the sprockets that are attached to and rotate an axis assembly 73 that drives the rotation of a pair of disc hubs 74 mounted on shaft assembly 73 and supporting seed disks 29 so that rotation of shaft assembly 73 rotates both seed disks 29. Clutches 69 can be, for example, electromechanical clutches or clutches, configured to selectively transmit the rotation of or prevent acute angle rotation transmission from the shaft (s) 67 to the shaft assembly 73, coupling or decoupling the energy between shaft (s) 67 and the shaft assembly 73 and therefore for seed discs 29.
    [036] Still with reference to Figures 3 to 5, the axis assembly 73 includes a first axis segment 73A that rotates the seed disk 29 in the seed meter 9 of the first row unit 11A and a second axis segment 73B that rotates the seed disk 29 in the seed meter 9 of the second row unit 11B. During the planting session, the first and second axis segments 73A, 73B are blocked for rotation in unison with each other. When the first and second axis segments rotate in unison with each other, the seeds released from the first and second row units 11A, 11B are distributed with seed spacing that is consistent between rows within each planted row segment 12A, 12B and consistent between row between seeds in the first planted row segment 12A and in the second planted row segment 12B. The seed between row and the plant spacing is mainly established by the spacing between the seed bags 31 of the seed discs 29. The seed between row and the plant spacing is mainly established and can be adjusted by the indexing system 61. The system Indexing 61 allows adjustment of the longitudinal spacing of the seed positions of the planted row segments 12A, 12B to achieve predetermined spacing characteristics by facilitating the arrangement of the seed discs 29 at the predetermined angular index positions with respect to each other. The predetermined angular index positions can be distinct positions of components of the indexing system 61 that provide corresponding amounts of angular indexing of the seed disks 29 based on the type of seed being singled out by the seed disks 29 and, for example, the spacing of the seed disks. said seed pockets 31 in the seed disks 29 and therefore the placement of seed in the planted row segments 12A, 12B of each double row 12.
    [037] Referring now to Figure 8, the indexing system 61 is illustrated with a disk hub indexing system 75 that is configured to support the disk hub 74 for adjustable movement with respect to the axis assembly 73 during the indexing adjustment procedure and then re-lock the disc hub 74 for rotation in unison with the shaft assembly 73. The disc hub 74 has a hub body 77 that can be plate type with a circular outer perimeter shape with the first and second outer surfaces 79, 81, respectively facing and away from the seed disk 29, a central part of which is shown in Figure 3. The disk hub 74 has ears 83 that extend from the end surface 79 that faces the seed disk 29. The ears 83 are configured to support the seed disk 29 by fitting the mounting holes 84 of the seed disk 29. Each ear 83 is a perimeter shape that extends collectively around the ears. first and second segments of the ear 83. The first segment of the ear 83 defines a main segment 85 of the ear 83 through which a hole 87 extends and which, from an end view, is generally circular. A second segment of the ear 83 defines a finger segment 89 which is, from an end point of view, generally elongated and extends tangentially away from the main segment 85 of the ear 83. A central hole 91 extends entirely through the hub body 77 on its central geometric axis and is configured to concentrically accommodate the axis assembly 73, such as the first and / or second axis segment 73A, 73B. As shown, the shaft assembly 73 is housed concentrically within the central hole 91 of the disc hub 74 and can rotate with respect to shaft assembly 73. The relative rotation of the disk hub 74 when the shaft assembly 73 is limited by interaction of the disc hub 74 and the hub hub 93 which is fixed with respect to the hub assembly 73. The hub hub 93 which can be plate type with a circular outer perimeter shape with first and second opposite end surfaces 97, 99 respectively towards and away from the seed disk 29. The hub hub 93 has a central hole 101 that extends entirely through the hub body 95 on its central geometric axis and is configured to concentrically accommodate the hub assembly 73. The axle hub fixing holes 103 extend radially through hub body 95 and are aligned with each other on opposite sides of hub body 95 and an axle hole 105 extends radially through hub assembly x 73. A pin 107 extends through the attachment of the axle hub and axle holes 103, 105 to secure hub body 95 and axle assembly 73 together, locking hub body 95 and axle assembly together 73 in rotation in unison with each other. The slits 109 extend through the entire thickness of the hub body 95 of the shaft 93. Each slot 109 has the first and second ends 111, 113 and defines an opening that is elongated and curved, generally parallel to the sternum perimeter of the hub body 95 between the first and second ends 111, 113.
    [038] Still with reference to Figure 8, the disc hub indexing system 75 includes a clamping ring 115 with a body 117 that can be ring-shaped or generally annular with the first and second end surfaces 119, 121 respectively facing and away from the seed disk 29. The clamping ring 115 has a central opening 123 through which the shaft assembly 73 extends and the lobes 125 extend radially outwardly from an outer circumferential surface of the body 117, spaced apart around a perimeter of the clamping ring 115. Each lobe 125 has a hole 127 that aligns with the holes 87 of the disc hub lobes 83. Fasteners 129 (only one illustrated) extend through holes 87 of the lobe disc 83, through axle hub slots 109 and no e are trapped within the clamping ring lobe holes 127. This provides a stacked arrangement of the disc hub indexing system 75 with the axle hub 93 sandwiched o between disc hub 74 and clamping ring 115, with respective end surfaces of disc hub 74, and axle hub 93, and clamping ring 115 engaging with each other. The tightening and loosening of the fasteners 129 allows the components of the disc hub indexing system 75 to be locked as a unit against each other or to allow relative movement of the disc hub 74 and the clamping ring 115 with respect to the hub axis 93 to adjust the indexing positions of the seed disk 29 during an indexing adjustment procedure. The indexing adjustment movement of disc hub 74 and clamping ring 115 with respect to shaft hub 93 is limited to the amount of travel allowed by fasteners 129 along the length of shaft hub slots 109 when the first and second stop positions defined when the fasteners 129 engage the first and second ends 111, 113 of the slits 109.
    [039] Referring now to Figure 9, the indexing system 61 is illustrated with an axis hub indexing system 131 which is configured to allow indexing adjustment procedures by adjusting the relative index positions of the first of seconds axis segments 73A, 73B with respect to each other. The axis hub indexing system 131 is a first axis hub 133 arranged to rotate in unison with the first axis segment 73A and a second axis hub 135 arranged to rotate in unison with the second axis segment 73B. The first and second axis hubs 133, 135 are configured to selectively engage with each other to convert rotation between the first and second axis segments 73A, 73B. Adjusting the relative angular or rotary index positions of the first and second axle hubs 133, 135 when engaging to lock the first and second axis segments 73A, 73B in unison rotation changes correspondingly the relative angular index positions of the first and second axis segments 73A, 73B and the corresponding seed disks 29 with respect to each other. The first axle hub 133 has a hub body 137 which can be plate-like with a circular outer perimeter shape with the first and second end surfaces 139, 141 facing towards and away from the second axle hub 135 respectively. A pin 143 extends from an intermediate part of the first surface 139 of the hub body 137 to the second axle hub 135 to lock the first and second axle hubs 133, 135 with each other. A locking shaft 145 extends from a central part of the first surface of the hub body 137 to the second hub hub 125 to maintain the alignment of the first and second hub hubs 133, 135 and the first and second bearing segments. axis 73A, 73B with respect to each other. A collar 147 extends from the second surface 141 of the hub body 137 to facilitate axial movement of the first shaft 133 with respect to the shaft assembly 73. The collar 147 has a first end 149 attached to a central part of the first shaft hub 133 and a second end 151 spaced from the first axis hub 133. The collar 147 has a circumferential side wall 155 that extends around a hole 157 that concentrically receives the first axis segment 73A. A slot 159 extends through the circumferential side wall 155 of collar 147. Pins 161 extend from an outer surface of the first axis segment 73A, with a pin 161 disposed within slot 159 to define a limited travel path of collar 147 and the first axis 133 is guided by the slot 159 which slides over the pin 161.
    [040] Still with reference to Figure 9, a polarization arrangement 163 drives the first axle hub 133 to the second axle hub 135 in a state of omission or rest that is temporarily overcome during the indexing adjustment procedure. The polarization arrangement 163 includes a pair of flanges 165 with a polarizing member illustrated as a spring 167 concentrically mounted outside the first axis segment 73A between the flanges 165, driving the flanges 165 apart. The pin 161 shown towards the left hand side retains the flange 165 shown towards the left hand side in place of the first axis segment 73A. The flange 165 shown towards the right hand side is attached to the second end 151 of the collar 147. The flanges 165 compress the spring 167, which drives the collar 147 and the first shaft hub 133 towards the second shaft hub 135. The second axle hub 135 has a hub body 169 which can be plate-like with a circular outer perimeter shape with the first and second opposing surfaces 171, 173 respectively facing away from the first axle hub 133.
    [041] Referring now to Figures 9 and 10, the holes 175 extend to an intermediate part of the first end surface 171 of the hub body 169 with openings facing the first shaft hub 133 to receive the pin 143 of the first axis hub 133 to lock the first and second hub axes 133, 135 together. Referring now to Figure 10, the holes 175 are spaced apart around the first end surface 171 of the hub body 169, illustrated as shown in different positions 175A, 175B and 175C. The alignment and insertion of the pin 143 in the holes 175 in the different positions 175A, 175B and 175C provides different predetermined indexing positions of the first and second axis segments 73A, 73B with respect to one another because the first axis hub 133 is rotatably fixed with respect to the first axis segment 73A, and the second axis hub 135 is pivotally fixed with respect to the second axis segment 73B. A central hole 177 extends to a central part of the first end surface 171 of the hub body 169, with an opening facing the first shaft hub 133. The central hole 177 is configured to receive the locking shaft 145 to hold the alignment of the first and second axle hubs 133, 135 and the first and second axle segments 73A, 73B with respect to one another, even when the insert axis 145 advances to and away from the lower wall 179 of the central hole 177 when the first axle hub 133 is released toward or away from the second axle hub 135 during the index adjustment procedure.
    [042] Referring now to Figures 11 to 13, the indexing system 61 is illustrated with a seed disk system with multiple index position 181 that is configured to allow for indexing adjustment procedures by adjusting which requires the seed disks 29 (Figure 11) mount on disk hub 74 (Figure 12) on the first axis segment 73A in just a first angular index position and on disk hub 74 (Figure 13) on the second axis segment 73B in just a second angular index position, providing a predetermined relative amount of angular index between the seed disks 29 in the seed meters 9 of the first and second row units 11A, 11B (Figures 3 to 5). Referring now to Figure 11, the seed disk 29 has first and second sets 183, 185 of mounting holes 84. The mounting holes 84 of the first set 183 have a first shape of perimeter 187 and the mounting holes 84 of the second set have a second shape of perimeter 189.
    [043] Referring now to Figure 12, the ears 83 of the disc hub 74 disposed on the first axis segment 73A have a first shape of perimeter 191 which corresponds to the first shape of perimeter 187 in the first set 183 of mounting holes 84 (Figure 11) of the seed disk 29. This allows the seed disk 29 to be mounted on the disk hub 74 on the seed meter 9 of the first row unit 11A in only a first mounting position, with the first set 183 of the holes assembly 84 fitted over the ears 83 with the first perimeter shape 191 (Figure 12), providing a predetermined angular index position of the seed disk 29 for the first row unit 11A (Figures 3 to 5).
    [044] Referring now to Figure 13, the ears 83 of the disc hub 74 disposed on the second axis segment 73B have a second shape of perimeter 193 which corresponds to the second shape of perimeter 189 of the second set 185 of mounting holes 84 (Figure 11) of the seed disk 29. This allows the seed disk 29 to be mounted on the disk hub 74 on the seed meter 9 of the second row unit 11B in only a second mounting position, with the second set 185 of the holes assembly 84 fitted over the ears 83 with the second perimeter shape 193 (Figure 13), providing a predetermined angular index position of the seed disk 29 for the second row unit 11B (Figures 3 to 5).
    [045] In any case, the indexing system 61 allows for quick and precise changes in the spacing characteristics between the double rows of seeds in the first segment of the planted row 12A and in the second segment of the planted row 12B (Figures 1 and 2) . The indexing system 61 does this by facilitating the adjustment of the relative amounts of rotary or angular indexing of seed disks 29 based at least in part on the type of seed being planted and the configuration of seed disks 29 to plant a specific type of seed . A desired spacing characteristic of the seed placement for the seeds in the first and second planted row segments 12A, 12B can be a function of an index disc angle between the seed discs 29 and the seed meters 9 of the first and second row units 11A, 11B and a spacing function of the adjacent seed bags 31 of the specific seed disk (s) 29. A desired disk index angle of the seed disks 29 of the seed meters 9 of the first and second row units 11A, 11B can be 60 degrees plus a half an index seed angle of each seed disk 29, provided by an angle defined between imaginary straight lines extending from adjacent seed bags 31 through of and converging on a geometric axis of rotation of the seed disk 29. For example, if imaginary straight lines extending from adjacent seed bags 31 through and converging on a geometric axis of route tion of the seed disk 29 set an index seed angle of 6 degrees, so the index disk angle of the seed disk 29 in each row segment 13 should be 63 degrees.
    [046] Many changes and modifications can be made to the invention without departing from its spirit. The scope of these changes will become clear from the attached claims.
