    FIELD OF THE INVENTION
    [001] This invention relates, in general, to row crop planters or planters and, in particular, to seed planters for planting multiple seed varieties. BACKGROUND OF THE INVENTION
    [002] Modern culture practices strive to increase yields from agricultural fields. Technological advances in planters allow for better agronomic characteristics at the time of planting, such as providing more accurate seed depth, improved seed depth uniformity side by side with the planter, and improved row spacing accuracy. However, a single field may have inconsistencies in performance between different areas. This is due to the fact that a field can have a wide variety of soil types and management zones, such as irrigated and non-irrigated zones in different areas. Seed companies are developing multiple varieties of each of their seed product types, where different varieties offer improved performance characteristics for different soil types and management practices. Efforts have been made to plant multiple varieties of a particular seed product type in different areas of fields with different soil types or management zones. These efforts include planters that have different bulk fill hoppers and require that the reservoir, for each seed meter, be completely emptied or planted before a different seed variety can be delivered to the seed meters. Some planters allow the planting of two varieties and include two separate and separate seed meters in each planting line unit. DESCRIPTION OF THE INVENTION
    [003] The present invention is aimed at a seed meter that has multiple, which can include four, internal seed disk sets that allow absolute and instant switching of seed types that are being planted during a single planting pass, without requiring multiple seed meters in each planting line unit or emptying or planting a first seed type before switching to a different seed type. The seed meter has multiple sets of seed disks that can include, for example, two pairs of seed disks in the seed meter housing to selectively plant up to four types of seed. The seed meter is configured to activate a single seed disk and disable the others, so that only seeds transported by the activated seed disk are delivered from the seed meter for planting at any given time, or can be controlled to provide a mixture of seed types. By synchronizing the activation and deactivation in motion of the different seed disks within the seed meter, an absolute and instantaneous switching of the type of seed being planted within a single row can be achieved, which may include changing or adjusting the delivery of mixed seed types in a highly controllable manner. In one embodiment, this can be achieved by synchronizing the activation and deactivation of the different seed disks within the seed meter to provide an alternate delivery of different seed types to provide a mixed distribution.
    [004] According to one aspect of the invention, a seed meter is provided for planting multiple types of seed in a single planting pass during row cropping of an agricultural field. The seed meter has a sustained housing relative to a planter's planting line unit and has multiple portions that define multiple seed chambers that receive, respectively, multiple types of seeds from a bulk storage system. The multiple sets of seed discs selectively deliver individual seeds of multiple different seed types from the casing for release into an agricultural field during row cropping of the agricultural field. The multiple portions of the wrapper can include a first portion that defines a first seed chamber, for receiving seeds of a first type, a second portion, that defines a second seed chamber for receiving seeds of a second type, a third portion, that defines a third seed chamber to receive seeds of a third type, and a fourth portion, which defines a fourth seed chamber to receive seeds of a fourth type. This allows multiple types of seed to be fed and maintained separately within a seed meter for selective release in different zones, types or varieties of an agricultural field, defined, at least in part, by characteristics related to the type of soil and / or management.
    [005] According to another aspect of the invention, a seed disk drive system is configured to activate and deactivate the multiple seed disk sets to selectively deliver a corresponding type among the first, second, third and fourth types of seed from the casing during row cropping of the agricultural field. The seed disk drive system selectively activates the first seed disk to rotate inside the enclosure to transport seeds of the first type of seed through the enclosure, the second seed disk to rotate within the enclosure to transport seeds of the second type of seed through the sheath, the third seed disk, to rotate within the sheath to carry seeds of the third type of seed through the sheath, and the fourth seed disk, to rotate within the sheath to carry seeds from the fourth type of seed through the envelope. This allows for a compact configuration of a seed meter that can switch instantly between planting seeds of multiple different types, and during a seed type switching event, the release of a final seed of a seed type is followed sequentially by an initial seed of another seed type, even within a single row, without creating a jump event to provide constant seed spacing in the row through the seed type switching event.
    [006] In accordance with another aspect of the invention, the first and second seed disks define a first pair of seed disks aligned, in general, transversely to each other within the seed meter housing, and the third and fourth seed disks define a second pair of seed disks, generally aligned transversely to each other within the seed meter housing. In this arrangement, the seed discs of each of the first and second pairs can, in general, lie side by side in the meter housing. The seed disks, side by side, can be arranged so that the seed disks of the first pair are generally parallel to each other within the seed meter enclosure, and the seed disks of the second pair are, in general, parallel to each other within the seed meter housing. The seed disks, side by side, can be arranged so that the seed disks of the first pair are at an angle to each other within the seed meter housing, and the seed disks of the second pair are to be at an angle to each other within of the seed meter housing. In one embodiment, the first and second pairs of seed disks converge towards each other over a seed tube configured to receive seeds released from each of the first, second, third, and fourth seed disks. This provides an X-shaped arrangement of the seed discs within the meter housing, with a projected tip or intersection area of the X-shaped arrangement aligned over an upper opening of a single seed tube. These multiple seed disks configured to release seed at substantially the same seed release location within the seed meter housing for delivery of a single seed tube, which reduces seed bounce within the seed tube and improves the consistency of delivery of seed to the agricultural field.
    [007] According to another aspect of the invention, a planter is provided for planting multiple types of seed in a single planting pass during row cropping of an agricultural field. The planter includes a frame, a bulk storage system supported by the frame and configured to store multiple types of seeds. Multiple row units are supported by the frame. In one embodiment, each of the multiple row units has a row storage system, with multiple compartments configured to receive the respective seed types from among the multiple seed types from the bulk storage system, and a flow meter. seed for planting multiple types of seed. Each seed meter has a housing that has multiple portions that define multiple seed chambers that receive, respectively, seeds of multiple types from the multiple compartments of the row storage system and multiple sets of seed discs. Multiple seed disc sets selectively deliver individual seeds of multiple seed types from the multiple seed chambers of the enclosure seed meter to release to an agricultural field during row crop cultivation of the agricultural field.
    [008] According to another aspect of the invention, in each row unit, the multiple compartments of the row storage system are defined by multiple mini-chambers of a mini-chambers arranged to deliver seeds to the seed meter. In one embodiment, the multiple mini-chambers include a first mini-chambers, arranged to deliver seeds of the first variety to the first seed chamber of the seed meter, a second mini-chambers, arranged to deliver seeds of the second variety to the second seed chamber of the seed meter, a third mini-chamber, arranged to deliver seeds of the third variety to the third seed chamber of the seed meter, and a fourth mini-chamber, arranged to deliver seeds of the fourth variety to the fourth chamber seed from the seed meter.
    [009] According to another aspect of the invention, the planter includes a distributor configured to selectively direct the seeds of the first, second, third and fourth types to the respective mini chambers among the first, second, third and fourth chambers of minitremonha. In one embodiment, the distributor includes distributor outlet ducts and a door system, which has doors that can be actuated to close or open the distributor outlet ducts to, respectively, block or allow flow through passages that extend through of the outlet ducts in the first, second, third and fourth mini-chambers. The distributor can be mounted with the distributor outlet ducts connected to the inputs of the first, second, third and fourth mini-chambers. This can provide the distributor in the mini-firewall itself. The distributor can be arranged upstream in relation to the mini-shaver. In this arrangement, the distributor can be connected or mounted within a primary seed conduit that receives seeds from the bulk storage system. In this arrangement, the distributor outlet ducts can connect to secondary seed ducts that extend from the distributor outlet ducts to the respective inlets between the inlets of the first, second, third and fourth mini-chambers. This provides a system for feeding seeds of different types through a single primary seed conduit, while separately storing and delivering different seed types to multiple seed chambers separate from the seed meter.

DESCRIPTION OF ACCOMPLISHMENTS OF THE INVENTION
    [012] Now, with reference to the drawings and specifically to Figure 1 and the simplified schematic representations of Figures 2 and 3, the seed meters 5 of planting line units 7 of a planter 9 are configured for planting multiple types or varieties of seeds. As explained in greater detail elsewhere in this document, each seed meter 5 can switch, for example, absolutely, instantly and automatically, between plantings of different types or varieties of seeds during a single planting pass of a row crop. an agricultural field with planter 9. Planter 9 can be one of the EARLY RISER® series planters available from Case IH and is typically pulled by a traction device, such as a tractor 11. Planter 9 has a frame 13 that supports the multiple planting line units 7 that are substantially identical. Each planting line unit 7 includes a respective seed meter 5 and various supporting components to support the seed meter 5, and corresponding soil penetrating components.
    [013] Now, with reference to Figure 1, these support components include a subframe 15 that is connected to the frame 13 of the planter 9 by means of a known parallel connection system 16 (Figures 6 and 7) and supports the meter seed 5 and opening and groove closing mechanisms 19 towards the front and rear ends of the planting line unit 7. Opening and closing mechanisms 17, 19 may include opening and closing discs, respectively, or other ground penetration tools for opening and closing a groove. Each planting line unit 7 can include a regulator wheel 21 configured to adjust the depth of the groove by limiting the soil penetration of the groove opening mechanism 17 while creating a groove, and a pressure wheel 23 can be arranged to roll on the closed furrow to firm the soil on the seed to further close the furrow and to promote favorable contact between the seed and the soil.
    [014] Now, with reference to Figures 2 and 3, in these embodiments, seeds 25 are kept in bulk storage in a bulk storage system 27 with at least one bulk fill hopper 29, shown here in each of the Figures 2 and 3 as having two central bulk fill hoppers 29 supported by the planter frame 13 9. The bulk storage system 27 has multiple compartments 31, shown here as spaces within each of the bulk fill hoppers 29 that they are separated by partition walls or partitions 33. In another embodiment, the compartments 31 are defined, by themselves, by separate and discrete containers, such as multiple bulk filling hoppers 29. In some embodiments, such as those shown in Figures 6 and 7, at least some of the bulk fill hoppers 29 are not centrally located in relation to planter 9 and remote to planting line units 7, but they are mounted on the planting line units 7, by themselves, in a gravity feed relationship with the respective seed meters explained in greater detail elsewhere in this document. Regardless of where the hoppers 29 are located, the different compartments 31 of the hoppers 29 can hold seeds 25 of a common plant type, but of different varieties or types 25a, 25b, 25e, 25d for planting in areas of different type or variety of an agricultural field, defined, at least in part, by characteristics related to at least one of the soil types and management types. Although seed 25 may be described elsewhere in the present document as different types 25a, 25b, 25c, 25d, it is understood that the description of the different types includes different varieties. In other words, the different types 25a, 25b, 25e, 25d of seed 25 include not only different varieties of the same plant species, but also different seed products. Different seed products may include seeds of different species, coated and uncoated seeds, such as insecticide-coated and insecticide-coated seeds. Different seed products can also include and house seeds in a bag and not house them in a bag, seed resistant to plant parasites and seed resistant to plant parasites, such as seeds resistant to cyst nematodes and non-resistant seeds cyst nematodes, herbicide-tolerant seed and non-herbicide-tolerant seed, or other different products. Different seed products may additionally include seeds from different crops, such as corn and soy.
    [015] Still with reference to Figures 2 and 3, two exemplary arrangements of seed meters 5 are shown in the two planting line units 7 as seed meters 5a and 5b in Figures 2 and 3 respectively, each of which you can plant multiple types or varieties of seed. Each seed meter 5 is shown with four, and therefore two pairs, measuring sets 26 to selectively deliver and selectively deliver different types 25a, 25b, 25c, 25d of seed 25 from seed meter 5. Of the two pairs of measuring sets 26 within each seed meter 5, as shown in Figures 2 and 3, a first pair, or previous pair, 26a of measuring sets 26 is relatively closer to tractor 11, and a second pair , or posterior pair, 26b of measuring sets 26 is relatively farther from the tractor 11. The measuring sets 26 towards the left side of the seed meter 5 are, in general, longitudinally aligned with each other, and the measuring sets 26 towards the right side of the seed meter 5 are, in general, longitudinally aligned with each other. Regardless of how measurement sets 26 are arranged within each seed meter 5, each seed meter 5 is operationally connected to an airflow system 34 (Figures 4 and 5) that includes a positive and a vacuum source for establishing positive and corresponding vacuum pressures and air flows to deliver seed 25 to seed meters 5 and to move seeds 25 through seed meter 5. The positive air pressure source and sources Vacuum pumps can be known pumps, fans, blowers and / or other known airflow system components. Each seed meter 5 has a housing 35 that defines the first and second side portions 37, 39 shown as including a left cover (LH) and a right cover (RH). In the seed gauges 5a, 5b of Figures 2 and 3, with the measuring sets arranged transversely 26, each of the left and right covers LH, RH has a vacuum inlet (VI) to connect the first and second side portions 37, 39 to the vacuum source of the airflow system 34. Each of the left and right caps LH, RR is shown with two vacuum inlets VI to connect the first side portion 37 to the vacuum source in two locations, with each vacuum inlet VI provides vacuum pressure for a respective measuring set 26 of the seed meter 5. An intermediate portion 41 of housing 35 is disposed between the first and second side portions 37, 39.
    [016] Still with reference to Figures 2 and 3, each seed meter 5 has a seed meter reservoir 43 that defines a multiple chamber, or reservoir, divided into quadrants inside the seed meter 5. In the previous pair 26a of measuring sets 26, a separator wall 45 within the seed meter reservoir 43 separates the seed meter reservoir 34 in a first seed chamber 47, which stores seeds of the first type 25a, and a second seed chamber 48, which stores seeds of the second type 25b, inside the seed meter housing 35. In the rear pair 26b of measuring sets 26, a separator wall 45 inside the seed meter reservoir 43 separates the seed meter reservoir 34 in a third chamber seed 49 that stores seeds of the third type 25c and a fourth seed chamber 50 that stores seeds of the fourth type 25d within the seed meter casing 35.
    [017] Still referring to Figures 2 and 3, the front pair 26a of measuring sets 26 includes a first seed disk set 51a that has a first seed disk 53a disposed within the first side portion 37 of the meter housing seed 35 and a second seed disk set 51b having a second seed disk 53b disposed within the second side portion 39 of the seed meter housing 35. Back pair 26b of measuring sets 26 includes a third seed disk set seed 51c having a third seed disk 53c disposed within the first side portion 37 of the seed meter housing 35 and a fourth seed disk assembly 51d having a fourth seed disk 53d disposed within the second side portion 39 of the seed meter housing 35. In this arrangement, the first and third sets of seed disks 51a, 51c are, in general, longitudinally aligned with each other within the first lateral portion 3 7 of the seed meter housing 35. The second and fourth sets of seed disks 51b, 51 d are, in general, longitudinally aligned with each other within the second side portion 39 of the seed meter housing 35.
    [018] Still with reference to Figures 2 and 3, each of the seed discs 53a, 53b, 53e, and 53d has an inward facing surface 55 towards, and defining, transverse outer peripheries of the first, second, third and fourth seed chambers 47, 48, 49, 50. The outwardly facing surfaces 57 of the seed discs 53a, 53b, 53c, 53d are facing towards, and are spaced from respective covers, left and right LH, RH, the first and second side portions 37, 39 of the seed meter housing 35. This provides vacuum pressure chambers 67 between each of the outwardly facing surfaces 57 of the first and third seed disks 53a, 53c and the left cover LH and between each outward facing surface 57 of the second and fourth seed disks 53b, 53d and the right cover RH of the first and second side portions of the seed meter housing 37, 39. The vacuum pressure in the vacuum pressure chamber (s) 67 allows qu and the seeds 25 are pulled and held against the pockets and / or seed holes 69 of the seed disks 53a, 53b, 53c, 53d to rotate the seeds 25 through the seed meter housing 35 to be released from the s ) seed disk (s) 53a, 53b, 53c, 53d within a discharge segment 71 at release locations 73 in the seed meter housing 35.
    [019] Still referring to Figures 2 and 3, the discharge segment 71 of the seed meter 5 is defined posteriorly to a forward facing wall 75 of the seed meter housing 35, between the inward facing surfaces 55 of the seed disks. seed 53a, 53b, 53c, 53d and the partition walls 77 extending from the ends of the partition walls 45. Each partition wall 77 extends transversely in opposite directions beyond the end of the respective partition wall 45. Thus, a first partition wall 77 extends in a transverse direction through the interior of housing 35, from side to side, from a front portion of the seed meter reservoir 43 between the first and second seed disks 53a, 53b. A second partition wall 77 extends in a transverse direction through the interior of housing 35, from side to side, from a rear portion of the seed meter reservoir 43 between the third and fourth seed disks 53c, 53d.
    [020] Now with reference to Figure 2, the seed disk assemblies 51a, 51b, 51c, 51 d are arranged in linear alignment and in parallel relation to each other. Within the previous pair 26a of measuring sets 26 of the seed meter 5, the seed disk sets 51a, 51b and the seed disks 53a, 53b are transversely aligned and arranged parallel to each other. Within the rear pair 26b of measuring sets 26 of the seed meter 5, the seed disk assemblies 51 c, 51 d and the seed disks 53c, 53d are transversely aligned and arranged parallel to each other. Seed disk 53e is directly behind and in linear alignment with seed disk 53a. Seed disk 53d is directly behind and in linear alignment with disk 53b.
    [021] As shown in Figure 3, the seed disk assemblies 51a, 51b, 51 and, 51 d are arranged in angled relationships to define an X-shaped arrangement within the 35 meter housing, with a projected tip or intersection area of the X-shaped arrangement aligned on the discharge segment 71 in the seed meter housing 35. Within the previous pair 26a of measuring sets 26 of the seed meter 5, the seed disk sets 51a, 51b and the seed disks 53a, 53b are aligned transversely and arranged at an angle to each other, while geometric axes of rotation of the seed disks 53a, 53b intersect to define an internal angle of less than 180 °. Within the rear pair 26b of measuring sets 26 of the seed meter 5, the seed disk sets 51 and, 51 of the seed disks 53c, 53d are transversely aligned and arranged at an angle to each other, while the geometric axes of rotation of the seed discs 53c, 53d intersect to define an internal angle of less than 180 °.
    [022] When comparing the two realizations of seed gauges 5 shown as seed gauges 5a and 5b of Figures 2 and 3 with the anterior and posterior pairs 26a, 26b of measuring sets 26, in general, transversely aligned and parallel or angled to each other, respectively, the angled seed disks 53a, 53b, 53c, 53c of seed meter 5b in Figure 3 have release locations 73 that are longitudinally aligned and spaced transversely and relatively closer to each other than the release locations longitudinally aligned and transversely spaced 73 of the arrangement shown in the seed meter 5a of Figure 2. Regardless of whether the seed disks 53a, 53b, 53c, 53d are arranged parallel or angled to each other, the release locations 73 within the seed meter 5 allow the seed 25 to be released from the respective seed disks 53a, 53b, 53c, 53d through an outlet 79 of the seed meter housing 35 and in an inlet 81 of a common single seed tube 83 which delivers seed 25 to the agricultural field. This arrangement allows for the selective release of one of the seed types 25a, 25b, 25c, 25d at a given time and / or a given area of an agricultural field, as controlled by a control system 85.
    [023] Still with reference to Figures 2 and 3, the control system 85 controls the selective delivery of the seed types 25a, 25b, 25c, 25d of the seed meter (s) 5 and the initial delivery of the types of seed. seed 25a. 25b, 25c, 25d of compartments 31 of bulk filling hoppers 29 for the first, second, third and fourth seed chambers 47, 48, 49. 50 of the seed meter reservoir (s) 43. The control system 85 includes a planter controller 87 and a tractor controller 89 that communicate operationally with each other, for example, via an ISOBUS connection, to coordinate the controls of planter 9, such as seed gauges 5 and tractor 11 (Figure 1), based on the zones of type or variety VZ1, VZ2. VZ3, VZ4 of the agricultural field, which can correspond to a type of seed or prescription map of variety PM as shown in Figure 5.
    [024] Still with reference to Figures 2 and 3, the planter controller 87 is shown including a controller 91 and a power supply 93. The controller 91 of the planter controller 87 can include an industrial computer or, for example, a controller programmable logic (PLC), together with corresponding software and adequate memory to store that software and hardware, including interconnecting interconnect conductors for power and signal transmission to control electronic, electromechanical and hydraulic components of the seed meter 5 and other planter components 9 Tractor controller 89 is configured to control tractor 11 operations, such as controlling driving, speed, braking, shifting, and other tractor operations. 11.0 Tractor controller 89 is shown to include a 95 controller and 97 power supply. tractor controller 89 is configured to control the functions of tractor 11 by controlling the various control systems GPS, transmission, engine, hydraulics, and / or other output of tractor 11. Like controller 91 of the planter controller 87, controller 95 of tractor controller 89 can include an industrial computer or, for example, a programmable logic controller , along with corresponding software and adequate memory to store that software and hardware including interconnect conductors for power and signal transmission to control the electronic, electromechanical, and hydraulic components of the tractor 11. A 99 tractor interface system is operationally connected to the controller tractor 89 and includes a monitor and various input devices to allow an operator to view the status and control various operations of the tractor 11 from inside the tractor cabin 11.0 tractor interface system 99 can be a MultiControl Armrest ™ console available for use with Case IH Maxxum ™ series tractors.
    [025] Now with reference to Figures 4 and 5, the control system 85 controls the load of the seed types 25a, 25b, 25c, 25d in the first, second, third, and fourth seed chambers 47, 48, 49, 50 of the seed meter reservoir 43, controlling a primary feed system 101. Primary feed system 101 is shown to have a single primary seed duct 103 to selectively target the different seed types 25a, 25b, 25c, 25d in the first, second, third and fourth seed chambers 47. 48, 49, 50. Seed measuring rollers 105 that can be calibrated corrugated rolls arranged in exits 107 of the bulk filling hoppers 29, or in separate compartments 31 of a single bulk filling hopper 29 that keeps seed types 25a, 25b, 25c, 25d in their separate compartments 31. Rollers 105 are driven to rotate by electric, pneumatic, or hydraulic motors (not shown), when controlled by the s control system 85 for controlling the release of seed types 25a, 25b, 25c, 25d from the respective compartment (s) 31 in a segment of the conduit 109 that connects to the primary seed conduit 103.
    [026] As shown in Figure 4, in this embodiment, the primary seed flue 103 connects to a distributor system 111 that selectively directs seed types 25a, 25b, 25c, 25d to a row storage system 113 that includes a ventilated mini-heater 115. The mini-heater 115 has separating walls that orthogonally intersect 117, dividing the internal space of the mini-heater 115 into divided compartments, shown as first, second, third and fourth mini-heater chambers 119a, 119b, 119c, 119d feed into and are connected to the first, second, third and fourth seed chambers 47, 48, 49, 50 of the seed meter reservoir 43. The control system 85 fills selectively and maintains the seed cluster level of the first and second mini-chambers 119a, 119b, 119c, 119d controlling the distributor system 111. The distributor system 111 has a distributor 121 that defines a body, in general, tubular with d output units 123a, 123b, 123c, 123d which directly connect, in this embodiment, to the openings or inlets 125 of each of the mini-chambers 119a, 119b, 119c, 119d in an input segment 127 of the mini-shader 115.
    [027] Still with reference to Figure 4, the dispensing system 111 includes a door system 131 that has doors 133 that can be actuated independently to close or open the outlet ducts 123a, 123b, 123c. 123d of distributor 121 to respectively block or allow flow through passages extending through outlet ducts 123a, 123b, 123c, 123d to control delivery in the first, second, third and fourth mini-chambers 119a, 119b, 119c, 119d. Each of doors 133 is shown as a pivoting blade with an actuator 135 configured to open or close doors 133, pivoting doors 133 around pins 137. Control system 85 controls actuators 135 to open a single door from among doors 133 and close the remaining doors 133 at any given time in a way that allows the single primary seed flue 103 to target the different seed types 25a, 25b, 25c, 25d in the respective mini-chambers 119a, 119b, 119c, 119d designed to store that particular type of seed types 25a, 25b, 25c, 25d. Seed level sensors 139 are arranged in mini-chambers 119a, 119b, 119e, 119d to provide signals that allow control system 85 to evaluate how many seeds 25 of the seed types 25a. 25b, 25c, 25d are in each of the four mini-chambers 119a, 119b, 119c, 119d. Thus, the compartments 31 of the centrally located bulk filling hopper (s) 29 feed and maintain the appropriate fill level (s) of the seed types 25a, 25b, 25c , 25d in mini-chambers 119a, 119b, 119c, 119d by means of the distributor system 111, as controlled by the control system 85.
    [028] Now with reference to Figure 5, the seed meter 5, the bulk storage system 27, the primary feed system 101, the dispensing system 111, and the row storage system 113, are mostly identical to those in Figure 4, so the descriptions are applicable here. The dispensing system 111 of Figure 5 differs from that of Figure 4 in the following ways. Unlike distributor 121, which is directly connected to input segment 127 of mini 115, as shown in Figure 4, each distributor 121 among planting line unit (s) 7 in the embodiment shown in Figure 5 is provided within the primary seed duct 103 itself or within a branch upstream of primary seed duct 103 relative to mini-shaver 115 and therefore upstream and spaced from mini-shader 115. In this arrangement, secondary seed ducts 141 extend from the ducts output 123a, 123b, 123e, 123d from distributor 121 to the respective inputs of inputs 125 of mini-chambers 119a, 119b, 119c, 119d.
    [029] Although all seed types 25a, 25b, 25e, 25d can be stored in bulk centrally in one or more bulk fill hoppers 29, this central seed storage 25 can be optional. In some embodiments, all four, optionally three, two, or one of the seed types 25a, 25b, 25c, 25d are stored centrally in bulk, with the rest of the seed types being supplied with hopper (s) in the row. In some embodiments, only hoppers in the row are used for bulk storage of seeds 25. Now with reference to Figures 6 and 7, these planters 9 have at least some bulk seed storage in the row. This can be in addition to, or in place of, central bulk seed storage.
    [030] Now with reference to Figure 6, this is a variation of the system described above with respect to Figures 4 and 5 that includes both bulk storage located centrally remote, and bulk storage in row of seed 25. Instead of storing all seed types 25a, 25b, 25c, 25d in centrally located bulk fill hoppers 29, Figure 6 shows a variation in which only one seed type with the largest required use volume seed type (s), shown as seed type (s) 25a, 25b which corresponds to the primary seed types, are stored in compartments 31 of the centrally located bulk filling hoppers 29 represented as seed types 25a, 25b stored in the bulk filling hopper 29a , 29b. The relatively minor required use type seed type (s), shown as seed types 25c, 25d as secondary seed types, are stored in bulk in the row of compartment 31 of the bulk fill hopper. in row 29, represented as bulk fill hopper 29c. In this embodiment, within each seed meter 5 of planter 9, the different seed disks 53a, 53b, 53c, 53d are fed with seeds 25 stored centrally or in a row, with one or more of the seed disks 53a, 53b, 53c .53d being fed from storage in the bulk row, as desired. In the embodiment shown in Figure 6, the seed discs 53a and 53b are shown in dashed circles with the seed disc 53a towards the rear of the planting line unit 7 and the seed disc 53b towards the front of the line unit of planting 7, closest to the planter frame 13 9. Seed disks 53c and 53d which are represented by dashed overlapping lines are behind seed disks 53a and 53b in the view provided in Figure 6, which would correspond to side-by-side relationships of the seed discs 53c, 53d and 53a, 53b when viewed from above, in accordance with this provision. The first measuring set 26 has its seed disk 53a fed by the first type of primary seed 25a from the first mini-chamber 119a of the mini-laboratory 115, which pneumatically receives the primary seed type 25a by itself from the hopper stores. bulk fillers located remotely and centrally 29a. The second measuring set 26 has its seed disk 53b fed by the second type of primary seed 25b from the second mini-chamber 119b of the mini-laboratory 115, which pneumatically receives the primary seed type 25b from the remote located stores. and centrally of the bulk filling hopper 29b. Seed disks 53c and 53d are fed by gravity with secondary seed types 25e, 25d from compartments 31 on opposite sides of partition 33 of the bulk fill hopper in row 29c.
    [031] Now with reference to Figure 7, this realization shows all seeds 25 stored in the bulk row. This realization shows a single bulk fill hopper in segmented row 29e with compartments 31 separated from each other by partition 33. Seeds 25 of seed types 25a, 25b are fed by gravity to seed disks 53a, 53b, respectively, inside the seed meter 5. Although shown with two compartments 31 inside the bulk fill hopper in row 29c that feeds the seed disks 53a, 53b inside the seed meter 5, it is fully appreciated that the bulk fill hopper in the row 29c may have another pair of compartments 31, and the seed meter 5 may have another pair of seed disks 53e, 53d fed by that pair of compartments behind those visible in that view, which would be in respective side-by-side relationships with each other , if viewed from above.
    [032] Again with reference to Figures 2 and 3, regardless of the particular location (s) and configuration (s) of bulk storage of the seed 25 and the distributor system 111, the control system 85 is configured to control each seed meter 5 to switch, for example, absolute, instantaneous, and automatically, between planting different types or varieties of seed 25 during a single row crop planting pass in an agricultural field with planter 9. This can be done according to predetermined criteria, for example, based on the VZ1, VZ2, VZ3, VZ4 variety zones of the agricultural field provided by the seed type or PM variety prescription map (Figure 8), to accommodate the plantation, selectively, seed types 25a, 25b, 25c, 25d based, at least in part, on characteristics related to the type (s) of soil and type (s) of management of the VZ1, VZ2 variety zones , VZ3, VZ4. Control system 85 can absolutely and instantly switch which seed types 25a, 25b, 25c, 25d are being planted by enabling and / or disabling seed disk assemblies 51a, 51b, 51c, 51 d to shut off three quarters of the meter seed 5 and only deliver seed 25 from the fourth or quadrant of the seed meter 5 that is not turned off, in a precisely synchronized manner.
    [033] Still referring to Figures 2 and 3, each seed meter 5 has a seed disk drive system 143 that is controlled by control system 85 for selectively enabling and / or disabling seed disk assemblies 51 a, 51b, 51c, 51 d. Each of the seed gauges 5 is shown with a seed drive drive system of the direct drive type 143 that has motor drives 145. Motor drives 145 can include pneumatic motors or electric motors that rotate the shafts 147 that secure and trigger the rotation of the seed discs 53a, 53b, 53c, 53d. It is understood that the motor drives 145 can instead rotate the seed discs 53a, 53b, 53c, 53d by rotating hubs, outer peripheries, or other portions of the seed discs 53a, 53b, 53c, 53d, or the drive system 143 can be configured as a non-direct drive system that drives the rotation of the seed discs 53a, 53b, 53c, 53d by means of clutches, sprockets, cooperating and driven by traction or other rotary shafts. Regardless, the control system 85 is operationally connected to each of the motor drives 145 or other components of the disk drive system 143 or to disengage and prevent the transmission of rotary drive energy from the motor drives 145 or engage and allow the transmission of rotational drive energy from the motor drives 145 or other power transmission components of the disk drive system 143 to each of the seed disks 53a, 53b, 53c, 53d.
    [034] Still with reference to Figures 2 and 3, the seed disks 53a, 53b of the previous pair 26a of measuring sets 26 are rotated away from the forward facing wall 75 of the seed meter housing 35. The seed disks 53c, 53d of the rear pair 26b of measuring sets 26 are rotated towards the forward facing wall 75 of the seed meter housing 35. In this way, the seed disks 53a, 53b, 53c, 53d are configured to transport seeds 25 from relatively outwardly arranged storage quadrants defined by the seed chambers 47, 48, 49, 50 that receive seeds from the respective mini chambers 119a, 119b, 119c, 119d towards the single seed tube 83 in the segment intermediate-defined discharge 71 from the seed meter housing 35.
    [035] Referring now to Figures 2, 3 and 8, during use, an operator first displays the seed type or PM prescription map of variety (Figure 8) on the computer interface or monitor of the tractor interface system 99, which would normally be inside the tractor cab. The PM prescription map displays which types or zones of variety VZ1, VZ2, VZ3 and VZ4 are located in which places in the agricultural field and which types of seed 25a, 25b, 25c, 25d can be planted in the zones of variety VZ1, VZ2, VZ3 and VZ4. As shown in Figure 6, in this embodiment, seed type 25a is shown as acceptable for use in the variety zone VZ1, which corresponds to a recommended variety A. Seed type 25b is shown as acceptable for use in the variety zone. variety VZ2, which corresponds to a recommended variety B. Seed type 25c is shown to be acceptable for use in the zone of variety VZ3, which corresponds to a recommended variety C. Seed type 25d is shown to be acceptable for use in variety zone VZ4, which corresponds to a recommended variety D. The operator inserts which type of seed 25a, 25b, 25c and 25d is stored in compartments 31 of the bulk storage system 27 through the tractor interface system 99. The map of prescription PM may also contain the seed population that must be planted for each type or variety of 25a, 25b, 25c and 25d. The seed population can also be varied within the field based on the type of soil, organic matter, etc. The seed size can also be entered into the 99 tractor interface system. This information can also be available in the database that is built from the desktop computer software when the PM prescription map is created.
    [036] Referring again to Figures 4 and 5, control system 85 then determines the seed level in each of the four mini-chambers 119a, 119b, 119c and 119d based on signal (s) from the corresponding 139 seed level sensors. If the seed level in mini-chambers 119a, 119b, 119c and 119d is below a predetermined level that corresponds to an amount needed to make at least one planting pass or start planting, then the control system 85 sends a signal to rotate the measuring roll (s) 105 of compartment 31 which holds the seed type 25a, 25b, 25c and 25d which has been determined to be low. This releases the particular low seed type (s) 25a, 25b, 25e and 25d from the bulk storage system 27 through the primary seed conduit 103. Control system 85 also sends a signal to actuate port 133 on outlet duct 123a, 123b, 123c, 123d of distributor 121 that corresponds to mini-chambers 119a, 119b, 119c and 119d, currently being filled to open that particular door 133 and close all others inside the distributor 121. This ensures that seed types 25a, 25b, 25c and 25d released from bulk storage system 27 are directed to the correct chamber within the mini-chambers 1 I9a, 119b, 119c and 119d of the mini-shawl 115. This The process is repeated for each of the mini-chambers 119a, 119b, 119c, 119d for which a low seed level is detected.
    [037] Referring again to Figures 2 and 3, using the tractor controller GPS 89, the control system 85 has the ability to determine which type (s) of seed 25a, 22b, 25c and 25d it must be planted by each of the 5 seed meters based on the PM prescription map (Figure 8). Control system 85 controls each of the 5 seed meters or their components to achieve the desired planting characteristics based on the PM prescription map and / or based on different characteristics of the different seed types 25a, 25b, 25c and 25d , such as size, density or spacing of target population or the like. This may include automatically adjusting at least one rotational speed of the seed disk to adjust the seed population, adjusting a seed singulator setting, turning on the vacuum, turning off the vacuum, adjusting the vacuum level, adjusting the position of the deflector, adjust the seed cluster level. Preferred settings for seed meter 5 can also be presented by the operator and based on historical data or data provided by seed supplier 25 or planter manufacturer 9. Adjusting seed meter 5 to obtain preferred settings can also be made by adjusting the vacuum settings for each of the 5 meters controlled manually or automatically from inside the tractor cab via the tractor interface system 99. Similarly, a singulator and a seed deflector for each of the sets of seed disk 51 a, 51 b, 51 e and 51 d of seed meter 5 can be controlled manually or automatically through the control system 85 for each planting line unit 7, which may include making the adjustment (s) ) actual physical (s) to the singulator and / or deflector, for example, via an electric solenoid or stepper motor attached to the singulator and / or deflector or the like that are controllable to make such adjustments. For example, if seed type 25a is to be planted from a private planting line unit 7 of planter 9, control system 85 commands the seed disk drive system 143 to activate the seed disk sets. seed 51 a and rotate and deliver seed type seed 25a from seed disk 53a, and command seed disk drive system 143 to disable seed disk assemblies 51b, 51c, 51 to prevent rotation and the delivery of seed 25 of seed types 25b, 25c and 25d from seed disks 53b, 53c and 53d to seed meter 5 of the private planting line unit 7. In addition, to rotate a seed disk 53a, 53b , 53c and 53d corresponding, the activation of the seed disk assemblies 51a, 51b, 51 and and 51 d may include turning on the vacuum which can be turned off in the respective seed disk assemblies 51a, 51b, 51c and 51 d. This can be done by controlling a valve located at vacuum inlet VI or otherwise operable between vacuum inlet V1 and the vacuum source. Activation of the seed disk assembly 51a, 51b, 51c and 51 d may additionally include loading or preparing the respective seed disk 53a, 53b, 53c and 53d, such as by applying a vacuum and pre-rotating for a predetermined amount of time for a predetermined amount of rotation to ensure that the seeds are ready for planting. Additional control of the seed meter 5 during the activation and / or use of the seed disk assemblies 51a, 51b, 51 and and 51 d may include adjusting the time and position of seed release from the respective seed disk 53a, 53b, 53c and 53d. This may include adjusting the front or front seed discs 53a, 53b, 53c, 53d for early or relatively earlier release, and adjusting the rear or rear seed discs for delayed or relatively delayed release to ensure that the seeds are released 25 are sent through the center of the seed tube 83. In addition to stopping the rotation of a corresponding seed disk 53a, 53b, 53c, 53d, disabling seed disk assemblies 51 a, 51 b, 51 c and 51 d may include turn off the vacuum that is applied to the respective seed disk assemblies 51a, 51b, 51c and 51 d. This can also be done by controlling a valve configured to adjust or turn on and off the vacuum applied to the 51 a, 51 b, 51 c and 51 d seed disk assemblies. Disabling the seed disk sets 51a, 51b, 51c and 51 d may further include unpreparing the respective seed disk 53a, 53h, 53c, 53d, such as turning the seed disk 53a, 53b, 53e, 53d on a reverse direction, away from the seed tube 83 before removing the vacuum to avoid dumping the seed through the seed tube 83 if the vacuum is off in the seed disk 53a, 53b, 53e, 53d.
    [038] This synchronized activation and deactivation of the seed disk sets 51a, 51b, 51c and 51 d provides a seed type switching event. During the seed type switching event, which may correspond to planter 9 and / or tractor 11 that crosses from one variety area to another according to the PM prescription map (Figure 8) and which is detected by the GPS of the tractor controller 89, the release of a final seed 25 of the previously planted type is subsequently followed by an initial seed 25 of a subsequent or currently planted seed type. This can be done on a single planting line without creating a jump event, maintaining a constant line seed spacing through the seed type switching event, where a line seed spacing in a transition between the first and the second seed types is the same row seed spacing within each of the first and the second seed types 25a, 25b, 25c and 25d. In one embodiment, the synchronized activation and deactivation of the seed disk sets 51a, 51b, 51c and 51 d are controlled to provide mixed delivery of the different seed types 25a, 25b, 25e and 25d, as a mixed distribution. The control system 85 can be programmed to specify a percentage of each of the different seed types 25a, 25b, 25c and 25d, and the seed disks 53a, 53b, 53c and 53d are activated and deactivated correspondingly to alternate and synchronize the delivery of different types of seed 25a, 25b, 25c and 25d in order to achieve the percentage or other metric of the mixed distribution. For example, control system 85 can control seed disk 5 to plant a seed of type 25a, two seeds of type 25b, a seed of type 25c, a seed of type 25d or another predetermined sequence or other sequence to ensure that the correct general population distribution is achieved.
    [039] Referring also to Figures 2 and 3, the control system 85 can be configured to individually control each of the seed meters 5 in this way to control the switching of the seed delivery 25 of any type within the first, second , third and fourth seed types 25a, 25b, 25c and 25d to deliver seeds 25 of a different type among the first, second, third and fourth seed types 25a, 25b, 25c and 25d on a per row basis. In another embodiment, the control system 85 is configured to control groups of seed meters 5 in the same way, in the same session of planter 9, for example, giving common commands for all seed meters 5 in (s) same session (s) of external wing (s) and / or internal or intermediate sections. This allows the control system 85 to control the switching between delivery of seeds 25 of different types 25a, 25b, 25c and 25d to the planter on a per-section basis. In yet another embodiment, control system 85 is configured to control all seed gauges 5 of planter 9 in the same way. This allows you to control the switching between the delivery of seeds 25 of the different types 25a, 25b, 25c and 25d in an entire planter base.
    [040] Several changes and modifications can be made to the invention without departing from its spirit. The scope of these changes will become evident from the attached claims.
