    "SEEDER SEED FEEDER WITH ACCELERATING WHEEL SYSTEM" The present invention relates to a seeder with seed metering with accelerator wheel systems. Each accelerator wheel system receives individualized seeds from a respective seed dispenser and spaces the seeds in relation to each other to correct timing and thus seed spacing anomalies being released by the seed disks of the seed dispensers in disk release events. Incorrect seeds and to adjust the seed speed to match the sowing speed to release the seeds for direct fall down on the field, without a horizontal speed. Spacing and timing are also improved by reducing delivery variation typically attributable to falling into a seed tube, instead rotating seeds uniformly from a generally direction of delivery down a seed disk instead for a generally horizontal delivery direction out of the accelerator wheel system, opposite the tractor and implement travel direction.

    FIELD OF THE INVENTION
    [001] The invention relates in general to planters / seeders for row planting and, in particular, to seeders with seed metering systems with accelerator wheel systems. BACKGROUND OF THE INVENTION
    [002] Modern agricultural practices try to minimize operating costs. One way to reduce operating costs is to operate agricultural equipment at relatively higher travel speeds, which reduces the amount of operating time to complete certain tasks. When operating equipment with higher travel speeds, it may be important to maintain the quality of operation that can be achieved while operating at relatively lower operating speeds. This can be especially difficult to achieve during sowing operations that require precise seed placement depth and spacing accuracy in order to maintain a good seed environment. Delivering individualized seeds with relatively higher equipment speeds can result in seed clutter in the furrows or otherwise provide inconsistent seed spacing. SUMMARY OF THE INVENTION
    [003] The present invention relates to a sower with seed metering having accelerator wheel systems that mitigate seed disorganization and improve spacing between seeds at relatively higher sowing speeds. The accelerator wheel system corrects timing and thus seed spacing anomalies being released by the seed discs of the seed dispensers in the event of an incorrect seed disc release. This is done by taking all the seeds from the seed disks, including any seeds released incorrectly by the seed disks, and appropriately spacing the seeds when receiving them and moving them within equally spaced cavities of an accelerator wheel. Spacing and timing are also improved by reducing delivery variation typically attributable to dropping into a seed tube by rotating evenly rotating seeds from a generally direction of delivery down from a seed disk to a direction of delivery generally horizontal out of the accelerator wheel system, opposite the direction of travel of tractor and implement. Rotating the throttle wheel releases the seeds from the throttle system at consistent release intervals. The throttle wheel increases the speed of the seeds to release the seeds from the throttle system with a horizontal speed component that is equal to the speed of travel of the seeder. This provides a relative velocity of the released seeds with respect to the soil or field of approximately zero, substantially eliminating seed clutter during planting.
    [004] According to another aspect of the invention, the speed of the seeds in the accelerator wheel system is increased substantially when compared to the speed of the seeds in the seed doser. This may include increasing the speed of the seeds in the throttle system by at least about five times, at least about eight times, or by at least about ten times more than that in the seed dispenser.
    [005] According to another aspect of the invention, a seeder is provided that includes a towable chassis behind a tractor through an agricultural field to plant seeds in the field during a planting session. The seeder is moved across the field in a seeder travel direction with a seeder speed (VSseeder). Multiple row segments are supported by the chassis. Each of the multiple row segments has a seed feeder with a seed feeder housing and is configured to single out seeds for individual delivery to the seed groove. The seed dispenser releases individual seeds out of a seed dispenser housing outlet, into an accelerator wheel system. The throttle system is configured to accelerate the individual seeds and release the accelerated seeds into the seed groove. The seeds are released by the accelerator wheel system in a seed release direction that is substantially opposite the direction of the sowing path and with an accelerated seed release speed (V Accelerated Seed Release) corresponding to a speed of the seeds released by the system accelerator wheel. The Value of Accelerated Seed Release includes a horizontal velocity component value (V-Release of Accelerated Seed-Horizontal) corresponding to a horizontal component of the Value of Accelerated Seed Release and where the value of V-Accelerated Seed Release is substantially equal to the value of VSemeadora. This provides a relative velocity of the released seeds with respect to the soil of approximately zero, substantially eliminating seed disorganization during planting.
    [006] According to another aspect of the invention, the seed dispenser has a seed disk rotating within the seed dispenser housing. The seed disc transports individual seeds through the seed dispenser housing to release out of an outlet of the housing and into the throttle system at a seed dispenser release speed (V Seed Doser Release). The throttle system additionally includes a throttle housing with an inlet aligned with a common passageway of the seed dispenser housing outlet, or defined by it, to receive individual seeds from the seed dispenser. A throttle wheel is arranged for rotation within the throttle housing. The throttle wheel receives the seeds from the throttle wheel housing and accelerates the seeds from the V Seed Release Vendor value for the V Accelerated Seed Release and releases the seeds through the accelerator wheel housing with the V accelerated-Horizontal Seed Release value substantially equal to the value of VSemeadora.
    [007] According to another aspect of the invention, the seed disk of the seed doser has seed disk cavities retaining the individual seeds in relation to the seed disk while the seeds are transported by the seed disk through the doser housing of seeds. The throttle wheel of the throttle system further includes throttle cavities retaining individual seeds in relation to the thrust wheel while the seeds are transported by the throttle wheel through the throttle housing. The throttle cavities can rotate at a relatively higher angular speed within the throttle housing than the seed disc cavities in the seed doser housing can rotate and the throttle wheel can be relatively larger in diameter than the disc of seeds. The accelerator wheel and the seed disk can be rotated by a common drive system. The drive system can drive one of the accelerator wheel and the seed disk, and the accelerator wheel and seed disk can be in drive connection and driven with each other, for example, by means of an intermediate gear.
    [008] According to another aspect of the invention, the throttle cavities extend into an outer circumferential surface of the throttle wheel. The outer circumferential surface of the throttle wheel may include ramped segments extending between the throttle cavities. Each ramped segment extends between a pair of throttle pockets with the respective pair of throttle pockets. The pair of throttle cavities includes an advancing throttle cavity and a trailing throttle cavity, with the advancing throttle cavity arranged relative to the front of the drag throttle cavity with respect to a direction of rotation of the accelerator wheel.
    [009] According to another aspect of the invention, each segment ramped between the throttle cavities may include a leading end close to the respective leading throttle cavity and a trailing end close to the respective drag throttle cavity. . The leading end of the ramped segment is spaced relatively farther from a geometric axis of rotation of the accelerator wheel than the trailing end of the ramped segment. Each ramped segment can extend at least partially angularly from the leading end to the trailing end, along a clamping radius with respect to the geometric axis of rotation of the accelerator wheel. This provides a generally perimeter sawtooth-like shape for the accelerator wheel. In each pair of adjacent ramped segments, a transition is defined between a first ramped segment and a second ramped segment. A first radius is defined between the trailing end of the first ramped segment and the geometric axis of rotation of the accelerator wheel. A second radius is defined between the leading end of the second ramped segment and the geometric axis of rotation of the accelerator wheel. A measurement change in radius value can be defined between the first radius of the trailing end of the first ramped segment and the second radius of the leading end of the second ramped segment. Each throttle cavity can at least partially define the transition between the respective first and second ramp segments arranged opposite the respective throttle cavity (s). In this way, each sprocket cavity can define the trailing sprocket cavity with respect to the first ramped segment and the advance throttle cavity with respect to the second ramped segment.
    [010] According to another aspect of the invention, the throttle housing includes a throttle housing outlet and a seed tube that extends away from the throttle housing outlet. The seed tube directs the seeds released by the accelerator wheel housing to the field. This makes it possible to place the accelerator wheel system between the seed tube and the seed dispenser, allowing the accelerator wheel system to provide correction of anomalous seed spacing and timing characteristics and to increase the seed speed in such a way that the seeds leave the seed tube at a speed of approximately zero relative to the field.

It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the present invention, are given by way of illustration and not by way of limitation.

    [021] Referring now to the drawings and specifically to the simplified schematic representations of figures 1 and 2, seeder 5 is shown with row units 7, each having a seed feeder 9 and an accelerator wheel system 11 which minimizes seed disorganization of the seeds being planted when delivering the seeds to an agricultural field at a backward speed that matches a forward speed of the sower 5, as explained in more detail elsewhere in this document. Seeder 5 can be or can include seeder components available from Case IH such as seeders in the EARLY RISER® series. Seeder 5 is towed behind a tractor 15 for travel across the field in a seeder travel direction with a seeder speed (VSeeder) and has a chassis 17 with a frame including a toolbar 19 that supports the multiple seed units. row 7, which are substantially identical. Each row unit 7 has ground engaging tools (not shown) which may 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 can also include a calibration wheel configured to adjust groove depth by limiting ground penetration of the ground groove opening mechanism while creating a groove and a pressing wheel to roll over. the closed furrow to firm the soil on the seed to further close the furrow and promote favorable seed contact with the soil. Seeds are stored in bulk at seeder 5 in a bulk seed storage system 21 that delivers stored seeds to row units 7. Referring now to figure 1, the seed storage system 21 is shown as a system central bulk storage with bulk filling tanks 23 that retain bulk seeds that will be delivered pneumatically from bulk filling tanks 23 to seed dispensers 9 in row units 7. Referring now to figure 2, the seed storage system 21 is shown as a bulk storage system in the row, with the bulk filling hoppers in row 25 that retain the bulk seeds that will be supplied by gravity to the seed feeders 9 in the row units 7.
    [022] Referring now to figures 3-4C, regardless of where the seeds are stored in seeder 5 and how the seeds are delivered to seed dosers 9 in row units 7 (figures 1 and 2), each doser seed 9 includes an internal seed disk 27 with seed disk cavities 29 for retrieving and loading individual seeds through the seed dispenser 9. In each row unit 7 (figures 1 and 2), the seed drive system seed disk 31 rotates the seed disk 27 of the seed dispenser 9 through a seed reservoir within the seed dispenser 9 to expose the seed disk cavities 29 to the seeds in the seed reservoir to capture the seeds in the disk cavities seed 29. Although shown as extending axially across the opposite surfaces of the seed disk 27 or between them, the seed disk cavities 29 may extend at least partially into a surface external circumferential surface of the seed disk 27. Seed dispensers 9 can be purely mechanical type seed dispensers 9 or can be pneumatic seed dispensers 9, as shown. Pneumatic seed feeders 9 are operationally connected to an air flow system 33 (figures 3-4C). The airflow system 33 can include a positive air pressure source and / or a vacuum source to establish positive and / or vacuum pressures and corresponding air flows for operation of the seed feeders 9 in the row units 7, such as within air pressure chambers of seed feeders 9. The source of positive air pressure and vacuum sources can be known pumps, fans, blowers and / or other known air flow system components. When the seed storage system 21 is configured with a central bulk storage system (figure 1), the air flow system 33 includes a seed transport air flow system that provides an air flow that drags the seeds seeds to move seeds from bulk storage in bulk filling tanks 23 through seed conduits to row units 7, such as to mini-shafts (not shown) that feed seed feeders 9. When seed feeders 9 are pneumatic positive pressure seed metering 9, the air flow system 33 is configured to provide a positive air flow and a corresponding positive pressure within the seed metering 9 to push seeds into the seed disk cavities 29 of the seed discs 27 and retain the seeds in them by means of positive pressure by introducing pressurized air into the seed feeders 9. When the seed feeders 9 are pneumatic vacuum pressure seed metering 9, the air flow system 33 is configured to provide a vacuum air flow and a corresponding negative pressure within the seed metering 9 to pull and retain the seeds in the disk disc cavities seeds 29 from the seed discs 27 by means of vacuum pressure introduced into the seed metering 9 by drawing air out of the seed metering.
    [023] Referring further to figures 3-4C, each seed feeder 9 has a seed feeder housing 35 that includes interconnected covers, shown as a seed side cover 37 and a vacuum side cover 39 that collectively close the inside of the seed dispenser 9 and cover the seed disk 27. The seed side cover 37 is arranged parallel and spaced from the seed disk 27. Referring now to figure 3, a seed reservoir 41 in which the seed cluster accumulates is defined in the space between the seed side cover 37 and the seed disk 27. A seed entrance 43 extends through the seed side cover 37 to define a passage such as an entry point that allows that seeds enter the seed reservoir 41 from the bulk seed storage system 21 or from the bulk storage system in the row, with the bulk fill hoppers in row 25 (figures 1 and two). Referring again to figures 3-4C, the vacuum side cover 39 is arranged parallel and spaced from the seed disk 27, on the other side of the seed disk 27 opposite to that of the seed side cover 37. A air pressure shown as the vacuum chamber 45, in which the vacuum pressure is created within the seed doser housing 35, is defined in the space between the vacuum side cover 39 and the seed disk 27. The inlet of vacuum 47 extends through the vacuum side cover 39 to define a passage through which air can flow out of the seed dispenser housing 35 to establish vacuum pressure within the seed dispenser 9. The release location 49 is defined within of the seed doser housing 35 where the seeds are released from the seed disk cavities 29, which can correspond to a vacuum elimination position in the seed doser housing 35. The seed doser housing 35 includes the seed doser housing output 51 which is configured to direct the seeds out of the seed doser housing 35 during seed doser exit events at the seed doser release speed (V Seed Doser Release), for the accelerator wheel system 11.
    [024] Referring also to figures 3-4C, the accelerator wheel system 11 mitigates seed disorganization and improves seed spacing at relatively higher seeder travel speeds. The accelerator wheel system 11 corrects timing and thus anomalies in seed spacing being released by the seed disk 27 of the seed dispenser 9 if there are incorrect seed disk release events and increases the speed of the seeds to release the seeds through the seed system. accelerator wheel 11 approximately with the speed of displacement of the VSemeader seeder to provide a relative speed of the released seeds with respect to the soil or field of approximately zero, substantially eliminating seed disorganization during planting. The throttle system 11 includes the throttle housing 53 with the inlet 55 that receives the individual seeds released out of the seed dispenser housing outlet 51 and a throttle housing outlet 57 that delivers the seeds into the seed tube 59 to direct the seeds from the accelerator wheel system 11 and thus from the row unit 7 (figures 1 and 2) to the seed groove. The accelerator wheel 61 is arranged for rotation within the accelerator wheel housing 53. An upper part of the accelerator wheel 61 is stacked transversely with respect to a lower part of the seed disk 27 (figures 4A-4C and 5) or overlapping it. The throttle wheel 61 has the throttle cavities 63 that hold the individual seeds while displacing the seeds through the throttle housing 53, from the inlet 55 to the outlet 57 for release through an outlet of the seed tube 59. The accelerator wheel 63 extends into an outer circumferential surface 65 that defines an external periphery of accelerator wheel 61.
    [025] Referring now to figures 5 and 6, the outer circumferential surface 65 of the throttle wheel 61 has the ramped segments 67 extending between respective pairs of the throttle cavities 63. Referring now to figure 6 and shown in part bottom of the throttle 61, each throttle cavity 63 has a front cavity wall 63A, a rear cavity wall 63B and a lower cavity wall 63C interconnecting the front and rear cavity walls 63A, 63B. The front and rear cavity walls 63A, 63B extend at non-perpendicular angles to the outer circumferential surface 65, extending angularly away from the direction of rotation of the accelerator wheel 61. The lower cavity wall 63C extends over a arc to connect the respective ends of the front and rear cavity walls 63A, 63B. Referring again to Figure 5, each throttle cavity 63 defines an advance throttle cavity with respect to the adjacent throttle cavity 63 behind it and also defines a trailing throttle cavity 63 with respect to the throttle cavity. throttle 63 in front of it, relative to the direction of rotation of the throttle wheel 61. Between each adjacent pair of seed cavities 63, each ramped segment 67 of the throttle wheel 61 has a leading end 69 near the first or seed seed cavity corresponding feed 63 and a trailing end 71 near the second or corresponding seed trail 63 cavity. As shown in figures 5 and 6, each ramped segment 67 has its lead end 69 (figure 5) connected to the outer end of the rear cavity wall 63B (figure 6) of the respective lead seed cavity 63 and extends in a direction away from the direction of rotation of the accelerator wheel 61 towards its trailing end 71 (figure 5) connected to the outer end of the front cavity wall 63A (figure 6) of the respective trailing seed cavity 63 of the seed cavity pair 63 at opposite ends of the ramped segment 67. The accelerator wheel 61 is shown with a perimeter shape in a generally sawtooth-like manner, although it is understood that the accelerator wheel 61 may have other perimeter shapes. The sawtooth-type perimeter shape is provided by a throttle wheel configuration 61 with the ramped segment advance end 69 spaced relatively farther from a throttle wheel rotation axis 61 than the ramped trailing end 71. Each ramped segment 67 extends at least partially at an angle, which can also curve from the lead end 69 to the trailing end 71, along a clamping radius with respect to the geometric axis of rotation of the accelerator wheel 61. Between a pair of adjacent ramped segments 67, a transition 73 providing a measure change in radius value of the accelerator wheel 61 is defined between the first radius of the ramped segment drag end 71 of a first ramped segment 67 of the pair and the second radius of the ramped segment lead end 69 of the second ramped segment of the pair. The transition 73 can be defined at least partially by the throttle cavity 63 between each pair of the ramped segments 67.
    [026] Referring again to figure 6, the ramped segments 67 cooperate with a guide 75 extending between the seed feeder housing outlet 51 and the throttle housing input 55. The guide 75 has a pair of guiding surfaces 77 that are angled with respect to each other, tapering downward from the seed dispenser 9 to the throttle system 11 to facilitate targeting the seeds falling from the release location 49 into the throttle system 11. A space between the upper ends of the guide surfaces 77 defines the seed feeder housing outlet 51. A space between the lower ends of the guide surfaces 77 defines the throttle housing input 55. A spacing correction arrangement 83 is defined by the guide 75, ramped segments of the throttle wheel 67, the throttle cavity 63 and by an internal surface 79 of a circumferential side wall 81 of the elevation accelerator wheel ojection 5, which cooperate with each other to provide correction of spacing of seeds released incorrectly by the seed doser 9 by facilitating receipt of seeds in cavity 63 as a spacing event again before planting. When seeds fall by the release location 49 with a seed feeder 9 through the guide 75, if a seed is not received immediately in the throttle cavity 63, then the seed will be retained momentarily within the spacing correction arrangement 83 until it is received in an advance sprocket cavity 63. This is because the seed is temporarily retained in a space 85 between the outer circumferential surface of the sprocket 65 and the inner circumferential side wall surface 79 of the sprocket housing 53 while the ramped segment 67 slides under the seed, gradually increasing the height dimension of the space 85 until an advance throttle cavity 63 passes underneath and receives the seed to load the seed through the rest of the throttle housing 53 until the seed reaches and passes through exit 57. For relatively larger seeds that do not fit in space 85, if the seed before it is not received immediately in a throttle cavity 63, the seed is retained in the guide 75 while the ramped segment 67 slides under it, until an advance throttle cavity 63 passes underneath and receives the seed to load the seed through from the rest of the throttle housing 53 until the seed reaches and passes exit 57.
    [027] Referring now to figures 1, 2 and 4A-4C, during use, the drive system 31 rotates the seed disk 27 (figures 4A-4C) and the accelerator wheel 61. The drive system 31 includes a transmission assembly 89 that selectively delivers power to the seed metering 9 and the throttle wheel system 11 to rotate the seed disk 27 (figures 4A-4C) and the throttle wheel 61, and is controlled by the control system 91 Control system 91 includes a tractor control system and / or seeder control system, which can include an industrial computer or, for example, a programmable logic controller (PLC), along with corresponding software and adequate memory for store such software, and hardware including interconnecting conductors for power and signal transmission to control electronic, electromechanical and hydraulic components of seed feeders 9, throttle system 11 for other components of seeder 5 and / o u of tractor 15. The control system 91 monitors the travel speed of the tractor 15 and thus the seeder speed VSemeader and controls the rotational speed of the throttle system 11 to provide a seed delivery speed desired by the throttle system 11 to match the VSeed of the seeder speed in such a way that the relative speed of the seeds released with respect to the soil or field is approximately zero, such as less than about 1 mph (1.6 km / h) or 0.5 mph (0.8 km / h), or low enough to prevent seed clutter that displaces the seed more than about 2 inches (5.08 cm) or more than about 1 inch (2.54 centimeters) in of the groove, as explained in more detail elsewhere in this document.
    [028] Referring to figures 1 and 2, the transmission assembly 89 is shown as the mechanical drive by chains 93 that delivers rotating drive power from a rotating shaft 95. The shaft 95 is driven to rotate by movement through the soil of the seeder 5, such as by means of a driving wheel of the type of traction drive, toothed drive wheel with soil, or can be rotated by a motor such as an electric motor, pneumatic motor or hydraulic motor. Clutches 97 are controlled by the control system 91 for fitting and detaching to selectively transmit shaft rotation 95 for chain movement of chain drives 93. It is understood that, instead of chains and sprockets, chain drive 93 can incorporate other power transmission components such as belts and pulleys. Referring now to figure 4A, chain drive 93 (figures 1 and 2) rotates a sprocket 99 attached to a rotary shaft of the accelerator wheel 101 connected to the hub 103 that supports and rotates the accelerator wheel 61. The gear set 105 includes gears 107 that actuately connect throttle wheel 61 to seed disk 27. Gears 107 transmit rotation from throttle shaft 101 to an axis 108 connected to hub 109 that supports and rotates the seed disk 27. Referring now referring to figure 4B, unlike the throttle wheel system 11 of figure 4A that initially drives the throttle wheel 61, the throttle wheel system 11 is shown configured to initially drive the seed disk 27. Chain drive 93 ( figures 1 and 2) rotate the sprocket 99 attached to the seed disk shaft 108 which rotates the hub 109 which rotates the seed disk 27. The gear set 105 transmits power from the seed disk shaft 108 to the throttle shaft 101 to rotate the hub 103 and the throttle wheel 61. It is understood that the chain drive 93 instead can drive an intermediate or counter shaft (not shown) which delivers power to turn both the seed disk 27 as the accelerator wheel 61 by means of separate chains receiving power from the counter axle. Referring now to figure 4C, it is understood that the transmission assembly 89 can be configured to separately drive rotation of the seed disk 27 and the accelerator wheel 61, as controlled by the control system 91. Figure 4C shows the system of drive 31 having an 88A motor such as an electric motor, pneumatic motor or hydraulic motor, controlled separately by the control system 91, and separately driving each of the seed disk 27 and the accelerator wheel 61. The 88A motors are shown with axles outlets connected coaxially and directly driving the axes 101, 108 and thus also driving the hubs 103, 109 and the accelerator wheel 61 and the seed disk 27, respectively. It is understood that the 88A engines can instead drive the hubs 103, 109 themselves or the accelerator wheel 61 and the seed disk 27, as such, by means of cooperating toothed surfaces of cogwheels or gear-type interfaces in external circumferential surfaces, flanges or other interfaces. Regardless of how the 88A engines drive rotation of the seed disk 27 and the throttle wheel 61, the 88B sensors are arranged with respect to the seed doser and throttle wheel housings 35, 53 to detect rotational speed (s) of the seed disk 27 and throttle wheel 61. Control system 91 receives signals from sensors 88B corresponding to the respective rotational speed (s) of the seed disk 27 and throttle wheel 61 and controls the 88A motors to synchronize the speeds to achieve the desired delivery rate and speed according to the control system 91 programming.
    [029] Referring again to the figures, 4A-4C, during use, the drive system 31 rotates the seed disk 27 and the throttle wheel 61 in such a way that the throttle cavity 63 has a greater angular speed than that of the seed disk cavities 29. This can be done by arranging the throttle cavity 63 radially further from a geometrical axis of rotation of the thrust wheel 61 than a radial distance from the seed disk cavities 29 to the axis of rotation of the seed disk 27 and also to rotate the accelerator wheel 61 with a higher rotational speed than that of the seed disk 27. In this way, seeds leave the accelerator wheel system 11 with a higher speed than that with which seeds leave the seed dispenser 9. The throttle system 11 can accelerate the seeds to a relatively higher speed in the throttle system 11, which can be at least about five times, at least s about eight times or at least about ten times greater than the speed of the seeds in the seed feeder 9. The rotational speed differential between the rotational speeds of the seed disk 27 and the accelerator wheel 61 can be provided by the gear set 105 when separately driving the seed disk 27 and the accelerator wheel 61 with different rotational speeds (figures 4A and 4B) or when directly driving the seed disk 27 and the accelerator wheel 61 with different speeds directly through the 88A engines ( figure 4C).
    [030] Referring again to figure 6, regardless of how the rotational speed differential between the rotational speeds of the seed disk 27 and the accelerator wheel is established, seeds are accelerated in the accelerator wheel system 11 when compared to the speed of seed in the seed doser 9. As represented by the vertical full-line arrow pointing downwards and identified by 111, each seed is released by the seed disk 27 through the seed doser housing outlet 51 with a release speed of seed doser (VSeed Doser Release), whose value is related to the angular velocity of the seed disk cavities 29 (figure 4) and to the acceleration due to gravity. The seed is directed through the guide 75 into the throttle system 11. The throttle system 11 accelerates the seed to a relatively higher speed and releases the seed out of the throttle housing outlet 57 and the feed pipe. 59 seeds, displacing with an accelerated seed release speed (V Accelerated Seed Release) in the direction of the seed groove. The Value of Accelerated Seed Release is represented by the angled full line arrow pointing away from the seed tube 59 and identified by 113. The Value of Accelerated Seed Release 113 has a vertically oriented velocity component and a horizontally oriented velocity component. . The horizontally oriented velocity component of the Accelerated Seed Release value 113 is shown as the horizontal velocity component value (V Accelerated Seed Release-Horizontal) as represented by the dashed line arrow pointing to the right and identified by 115. O value of V-Release of Accelerated-Horizontal Seed 115 is in the opposite direction and substantially equal to the value of VS-seeder of the seeder speed as represented by the dashed line arrow pointing to the left and identified by 117. This provides a relative speed of the seeds released with relative to the soil of approximately zero, substantially eliminating seed disorganization during planting.
    [031] Referring also to figure 6, to maintain a relative speed of the released seeds with respect to the ground of approximately zero, the control system 91 evaluates data corresponding to signals coming from a pair of the seed sensors 119 that are spaced one on the other and arranged in the seed tube 59 and configured to detect seed moving beyond each sensor 119. The control system 91 calculates the Accelerated Seed Release V value 113 and / or the Accelerated Horizontal Seed Release V value 115 by dividing the fixed distance between the seed sensors 119 by the time it takes for the seed to travel from the first sensor 119 upstream to the second sensor 119 downstream. The control system 91 evaluates the value of V-Release of Accelerated-Horizontal Seed 115 in relation to the value of VSemeadora 117 that can be determined by the control system 91 based on a signal coming from the speed sensor 121 arranged in the tractor 15 (figures 1 and 2). If the control system 91 identifies a discrepancy between the value of V-Release Accelerated-Horizontal 115 and the value of VSemeader 117, the control system 91 commands the drive system 31 to rotate the accelerator wheel 61 at a higher rotational speed or lower to attenuate the discrepancy between the value of V-Release of Accelerated-Horizontal Seed 115 and the value of VSemeadora 117.
    [032] Many changes and modifications can be made to the invention without departing from its spirit. The scope of these changes will become apparent from the attached claims.
