Description

Atty. Dkt. 24186WOSEED METERCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Application Nos. 63 / 697,032, filed 20 September 2024, and 63 / 860,086, filed 8 August 2025, all of which are incorporated herein by reference in their entireties.BACKGROUND

[0002] Agricultural row crop planters typically include a seed hopper connected to a seed metering system that delivers seeds into a furrow formed by disc opener blades. A plurality of these row crop planters are typically mounted in parallel along a tool bar which is attached to a tractor. For example, it is common as of the time of this filing to have twenty-four, thirty-six, or even forty-eight row units attached to a single tractor.

[0003] Within a typical prior art row crop planter, seeds are delivered in bulk from the seed hopper to the metering system. The metering system precisely singulates the bulk seeds, and will most preferably provide these singulated seeds at very predictable and repeatable time intervals. There has been much development of improved metering systems, and these in general have proven to be quite reliable. The row crop planter subsequently delivers one seed at a time into the ground, typically into a furrow cut by the opener blades.

[0004] One common prior art method of seed delivery from the seed hopper to the ground is a gravity drop system that locates a seed tube inlet below the seed metering system. A singulated seed drops from the metering system down the seed tube and into a furrow prepared by opener blades disposed forward of the seed tube. This standard method of seed delivery, while a vast improvement over older techniques, leaves room for improvement in desired seed placement and orientation.

[0005] Crop yields are affected by a variety of factors, such as seed placement, soil quality, weather, irrigation, and nutrient applications. Seeds are typically planted in trenches formed by discs or other mechanisms of a planter row unit. Depth of seed placement is important because seeds planted at different depths emerge at different times, resulting in uneven crop growth. Spacing of seeds can affect yield because plants that are too close together compete for nutrients, and plants too far apart leave wasted space between them. Orientation of seeds can affect time to plant emergence, and therefore, uniformity of plant growth, as well as canopy closure andAtty. Dkt. 24186WO shading from adjacent plants. It would be beneficial to have improved methods of controlling the position and orientation of seeds placed in trenches so that seeds emerge and grow more uniformly.

[0006] There are several methods of orienting seeds for planting. Examples of orientation systems include PCT Publication Nos. WO2018013858A1, WO2018013859A1, W02018013860A2, and W02018013861A1. One particular type of seed orienter is described in U.S. Patent Publication No. US2020 / 0367425A1 and US2022 / 0192079A1, each which disclose a seed orientation coil. Seed is accelerated with air injected into the coil, and the air is dissipated via at least one vent.BRIEF SUMMARY

[0094] FIG. 1 illustrates an embodiment of an agricultural planter row unit 100. The row unit 100 has a frame 110 pivotally connected to a toolbar 112 by a parallel linkage 114, enabling each row unit 100 to move vertically independently of the toolbar 112 and of other row units 100. The frame 110 operably supports one or more hoppers 116, a downforce control system 118, a seedtrench opening assembly 120, a seed-delivery device 126, a seed-trench closing assembly 146, a packer wheel assembly 154, and a row cleaner assembly 162. The row unit 100 shown in FIG. 1Atty. Dkt. 24186WO may be used with a conventional planter or with a central fill planter, in which latter case the hoppers 116 may be replaced with one or more mini-hoppers and the frame 110 modified accordingly as would be recognized by those of skill in the art.

[0095] The downforce control system 118 is disposed to apply lift and / or downforce on the row unit 100, such as disclosed in U.S. Patent 9,408,337, "Agricultural Row Unit Apparatus, Systems and Methods," granted August 9, 2016.

[0096] The seed-trench opening assembly 120 includes a pair of opening discs 122 rotatably supported by a downwardly extending shank 124 of the frame 110. The opening discs 122 are arranged to diverge outwardly and rearwardly so as to open a V-shaped seed trench 104 in the soil 102 as the planter traverses the field in a forward direction D.

[0097] The seed-delivery device 126 includes a seed meter 128 and a seed tube 130 that together may deliver seeds at a preselected rate to the soil 102. The seed meter 128 may be any commercially available seed meter, such as the fingertype meter or vacuum seed meter, such as the vSet® meter, available from Precision Planting LLC, 23333 Townline Rd, Tremont, Ill. 61568. The seed meter 128 may be configured to orient seeds in a preselected orientation to the seed tube 130 by any selected method, such as that shown and described in U.S. Patent Application Publication 2019 / 0230846, "Systems, Implements, and Methods for Seed Orientation with Adjustable Singulators During Planting," published August 1, 2019.

[0098] The seed tube 130 is positioned between the opening discs 122 to deliver seed from the seed meter 128 into the opened seed trench 104. The depth of the seed trench 104 is controlled by a pair of gauge wheels 134 positioned adjacent to the opening discs 122. The gauge wheels 134 are rotatably supported by gauge wheel arms 136, which are pivotally secured at one end to the frame 110 about pivot pin 138. A rocker arm 140 is pivotally supported on the frame 110 by a pivot pin 142. Rotation of the rocker arm 140 about the pivot pin 142 sets the depth of the seed trench 104 by limiting the upward travel of the gauge wheel arms 136 (and thus the gauge wheels 134) relative to the opening discs 122. The rocker arm 140 may be adjustably positioned via a linear actuator 144 mounted to the row unit frame 110 and pivotally coupled to an upper end of the rocker arm 140. The linear actuator 144 may be controlled remotely or automatically actuated as disclosed, for example, in U.S. Patent 9,864,094, "System for Soil Moisture Monitoring," granted January 9, 2018.Atty. Dkt. 24186WO

[0099] A downforce sensor may be configured to generate a signal related to the amount of force imposed by the gauge wheels 134 on the soil 102. In some embodiments, the pivot pin 142 for the rocker arm 140 may comprise the downforce sensor, such as the instrumented pins disclosed in U.S. Patent 8,561,472, "Load Sensing Pin," granted October 22, 2013.

[0100] The seed-trench closing assembly 146 includes a closing wheel arm 148 that pivotally attaches to the row unit frame 110. A pair of offset closing wheels 150 are rotatably attached to the closing wheel arm 148 and are angularly disposed to "close" the seed trench 104 by pushing the walls of the open seed trench back together over the deposited seed 106. An actuator 152 may be pivotally attached at one end to the closing wheel arm 148 and at its other end to the row unit frame 110 to vary the down pressure exerted by the closing wheels 150 depending on soil conditions. The seed-trench closing assembly 146 may be of the type disclosed in U.S. Patent 9,848,524, "Agricultural Seed Trench Closing Systems, Methods, and Apparatus," granted December 26, 2017.

[0101] The packer wheel assembly 154 includes an arm 156 pivotally attached to the row unit frame 110 and extends rearward of the seed-trench closing assembly 146 and in alignment therewith. The arm 156 rotatably supports a packer wheel 158. An actuator 160 is pivotally attached at one end to the arm 156 and at its other end to the row unit frame 110 to vary the amount of downforce exerted by the packer wheel 158 to pack the soil over the seed trench 104.

[0102] The row cleaner assembly 162 may be the CleanSweep® system available from Precision Planting LLC, 23333 Townline Rd, Tremont, Ill. 61568. The row cleaner assembly 162 includes an arm 164 pivotally attached to the forward end of the row unit frame 110 and aligned with the seed-trench opening assembly 120. A pair of row cleaner wheels 166 are rotatably attached to the forward end of the arm 164. An actuator 168 is pivotally attached at one end to the arm 164 and at its other end to the row unit frame 110 to adjust the downforce on the arm to vary the aggressiveness of the action of the row cleaner wheels 166 depending on the amount of crop residue and soil conditions.

[0103] The row unit 100 may optionally carry other sensors 170. In some embodiments, for exemplary and non-limiting purpose, sensors 170 detect soil conditions before and / or after planting. In some embodiments, again for exemplary and non-limiting purpose, sensors 170 include sensors that monitor seed presence and flow, seed spacing, or other parameters useful to monitoring the proper operation of a seed orientation system.Atty. Dkt. 24186WO

[0104] FIGs. 2 and 3 illustrate in further detail one embodiment seed-delivery and orientation apparatus that may be used in the row unit of FIG. 1. As evident from FIG. 2, an exemplary disc 122 is suspended from shank 124 and opens a furrow in the earth just ahead of a subfurrow opener 170. Seed-delivery device 126 includes seed meter 128 and seed conveyor and orientation assembly 200. Seed meter 128 receives seeds 106 from seed hopper 116, singulates seeds 106, and then conveys singulated seeds 106 to seed conveyor and orientation assembly 200. Seed conveyor and orientation assembly 200 preferably delivers oriented seeds 106 from oriented seed exit path 244 into a subfurrow opened by subfurrow opener 170.

[0105] As best illustrated in FIG. 3, which provides a view similar to that of FIG. 2 but with the exemplary disc 122 and shank 124 removed for purposes of illustration, conveyor belt 201 delivers seed 106 from seed meter 128 to seed orientation coil assembly 240. Seed 106 arriving from conveyor belt 201 will most preferably slide along a surface within seed conveyor exit 230, most preferably free from bounce, tumbling, or other the like. Seed 106 passes from seed conveyor exit 230 into an optional seed collector 232, which provides a suitable coupling between conveyor belt 201 and seed orientation coil assembly 240.

[0106] In the region adjacent to seed collector 232, seed riding surface 292 is fully enclosed and unvented. However, shortly thereafter and continuing as the seed traverses helical pathway 290, the helical pathway is provided with an open side that acts as a vent 268. This surface may be entirely open as illustrated in FIGS. 2 and 3. In alternative embodiments the surface is covered by an air-permeable surface that may for exemplary and non-limiting purpose comprise holes drilled with a laser, drill bit, chemical milling, or any other suitable technique. In yet other alternative embodiments, vent 68 is fabricated from a porous, micro-porous, or otherwise gas- permeable material which provides venting throughout the exterior wall, including for exemplary and non-limiting purpose: a porous material including but not limited to a mesh or screen; sintered metals; porous carbon; porous carbon-graphite; porous carbon-silicates; open-cell foams of any suitable composition; and other breathable materials and compositions. In some alternative embodiments, venting will be provided only selectively at strategic locations, or in other alternative embodiments entirely along seed riding surface 292.

[0107] Vented outer coil 260 may comprise any number of degrees of rotation, though as illustrated comprises approximately a single 360 degree rotation. The relatively small diameter helps to increase the centrifugal force generated therein. After passing through vented outer coilAtty. Dkt. 24186WO260, seed will then pass into and through oriented seed exit path 244. The operation of this type of seed orienter is further described in U.S. Patent Publication No. US2022 / 0192079A1, entitled “Aerodynamic and Centrifugal Seed Orientation System for Agricultural Planters,” published June 23, 2022.

[0108] In some embodiments, seed collector 232 will incorporate an air infeed into seed orientation coil assembly 240, such as taught by U.S. Patent Publication No.US2022 / 0192079A1. In such embodiments, the air infeed will preferably drive air through an air injector nozzle into helical pathway 290. In the region adjacent to the air infeed, such as within seed collector 232, helical pathway 290 is preferably fully enclosed and unvented. However, shortly thereafter vented outer coil 260 is provided with an open interior vent 268, which may be entirely open as illustrated, or which in alternative embodiments is covered by an air-permeable surface.

[0109] In some alternative embodiments, an air infeed is positioned farther along helical pathway 290, intermediate between seed collector 232 and the aft end of oriented seed exit path 244, such as illustrated by injector core 58 described in U.S. Patent Publication No.2020 / 0367425 Al. In such embodiments, seed entering into seed orientation coil assembly 240 will most preferably be delivered with appropriate velocity to traverse seed riding path 292 and, where provided, gently engage with a seed guide wall.

[0110] Conveyor belt 201 is, in most embodiments, configured to accelerate seeds 106 so that when the seeds are released from seed conveyor exit 230 into seed collector 232 and seed riding path 292, they have enough energy for seed orientation coil assembly 240 to orient the seeds and enough momentum to carry them to the ground. Conveyor belt 201 is, in most embodiments, further configured to retain uniform seed spacing by eliminating timing errors due to dynamic effects of the row unit.[OHl] While the inclusion of seed orientation coil assembly 240 can be used in some embodiments, in some alternative embodiments no seed orientation apparatus other than conveyor belt 201 is provided. In alternative embodiments, seed conveyor and orientation assembly 200 is configured to orient seeds in a preselected orientation by other suitable seed orientation apparatus, such alternatives as shown and described in U.S. Patent Application Publications 2020 / 0367425, entitled “Seed Orientation System for Agricultural Planters” and published November 26, 2020, and 2022 / 0192079, entitled “Aerodynamic and Centrifugal SeedAtty. Dkt. 24186WOOrientation System for Agricultural Planters” and published June 23, 2022, and as also described herein below.

[0112] In other alternative embodiments, seed meter 128 is configured to orient seeds before or as they are delivered to seed conveyor and orientation assembly 200. For example, seed meter 128 may include a vision system and a singulator with features (e.g., lobes) configured to orient seeds, such as shown in FIGS. 4A-4C of U.S. Patent Application Publication 2019 / 0230846, "Systems, Implements, and Methods for Seed Orientation with Adjustable Singulators During Planting," published August 1, 2019. In yet other alternative embodiments other types of seed orientation systems will be used, including but not solely limited to those described in the background section herein above.

[0113] Seed-delivery device 126 is illustrated in simplified form in FIG. 4, including both seed meter 128 and seed conveyor and orientation assembly 200. Seed-delivery device 126 receives seeds 106 from seed hopper 116, singulates seeds 106 in seed meter 128, and then conveys singulated seeds 106 from seed meter 128 to seed conveyor exit 230.

[0114] In one embodiment, seed meter 128 has a seed disc 131 (metering unit) that rotates in a direction indicated by arrow 133 about a shaft 135 rotatably mounted in the seed meter. Seed meter 128 is preferably of the vacuum type as is known in the art, such that a vacuum source (not shown) creates a vacuum behind seed disc 131 (on the perspective of FIG. 4), thus creating a pressure differential across apertures 129 in the disc. As the apertures 129 rotate past a pool of seeds in the location generally indicated by reference numeral 127, the pressure differential causes an individual seed 106 to become entrained on each aperture 129 such that the seeds are carried by the disc as illustrated. The size and spacing of the holes may vary based on the type of seed to be planted. As the apertures cross a boundary such as axis 196, preferably at approximately the 3 o'clock position of the seed disc 131, the vacuum source is substantially cut off (e.g., by termination of a vacuum seal as is known in the art) such that the seeds 106 are released from the disc as they cross axis 196. In one embodiment, seeds 106 fall from the disc in a substantially vertical fashion along an axis 192 and drop into seed conveyor and orientation assembly 200 properly singulated and timed. In another embodiment, seeds 106 can be entrained directly into brush bristles or flights 206 as described in U.S. Patent Nos. US8813663B2, US8850998B2, US9480199B2, US9510502B2, US9661799B2, US9686906B2, US9699955B2,Atty. Dkt. 24186WOUS9807922B2, US9807924B2, US9820429B2, US9861031B2, and US 10004173B2. In another embodiments, the metering unit can be metering member 100 as described in US8850998B2.

[0115] Seeds 106 may in some embodiments arrive at seed conveyor and orientation assembly 200 with inertia and momentum that might not align with and follow the subsequent seed path, for exemplary and non-limiting purpose tumbling and / or bouncing. Allowing a seed 106 to tumble, bounce, or otherwise take an indirect path through seed conveyor and orientation assembly 200 can lead to substantial variation in time required to traverse from seed meter 128 into the earth. Said another way, a seed 106 which follows a curved seed path between two points will require more travel time than a seed 106 traveling at the same speed but that bounces off the seed path and thereby travels in a straight line between the same two points. This results in inconsistent seed spacing that can lead to undesirable crowding of seeds and commensurate greater-than-desired gaps. To limit the impact of this unpredictable seed path timing, slower planting speeds that are more tolerant of the timing variances has heretofore been required.

[0116] In accord with the teachings of the present invention, seed conveyor and orientation assembly 200 is provided to stabilize and constrain these individual and sequential seeds 106 to slide upon seed riding surface 292. For the purpose of the present disclosure, a seed constrained to sliding upon seed riding surface 292 will be substantially free of tumbling or bouncing, and will instead slide along seed riding surface 292 in substantially continuous contact therewith. When seed 106 is so constrained, there will be a force generated by the friction of the seed sliding over the surface, or an equivalent thereto, that is in a direction generally opposite to the direction of travel of the seed along the seed path.

[0117] Seed conveyor and orientation assembly 200 includes a conveyor belt 201 stretched around an upper and a lower pulley. Examples of this belt arrangement are described in Figures 2A-2C and the associated text in PCT Publication WO2013 / 049198, and are available in the SpeedTube™ system from Precision Planting LLC of Tremont, Illinois. Drive apparatus 204 may for exemplary and non-limiting purpose comprise a rotary drive motor and pulley on a first end, and an idler pulley distal thereto. In other embodiments the seed conveyor and orientation assembly 200 will be driven by the lower pulley and in yet other embodiments with different motor types and constructions. Nearly all modern agricultural row planting equipment is equipped with one or more of a suitable source of electricity, pressurized air, hydraulic fluid, and motive power. In consideration thereof, for exemplary and non-limiting purpose drive apparatusAtty. Dkt. 24186WO204 may derive power from one of these sources and so comprise an electric motor, a pneumatic drive, a hydraulic drive, a friction wheel, a gear drive, or the like. In most embodiments, conveyor belt 201 and seed meter 128 are preferably driven at a speed proportional to or otherwise related to and dependent upon the ground speed of row unit 100, in order to provide a consistent seed spacing reasonably independent of ground speed of agricultural planter row unit 100.

[0118] Conveyor belt 201 as illustrated has an endless central belt 202 and a plurality of brush bristles 203 (e.g., impellers) securely affixed with and protruding outward from central belt 202. Nevertheless, in some alternative embodiments other impellers are used instead of brush bristles 203, for exemplary and non-limiting purpose such as flights disclosed in the aforementioned PCT Publication WO2013 / 049198 or a resilient or elastomeric material such as a foam rubber or elastic sheet of suitable geometry.

[0119] Seed conveyor and orientation assembly 200 additionally includes a guide surface 210 on one side of the seed conveyor, disposed adjacent to brush bristles or flights 203. Guide 210 includes an angled seed collector 218, along which each seed 106 slides downward when released from seed disc 131, where it will become captured between guide 210 and brush bristles or flights 203.

[0120] As illustrated, the spacing of endless belt 202 from guide 210 is selected so that a seed 106 traversing guide 210 will be pressed into and held against guide 210 in a non-damaging manner, and will not be allowed to slip between brush bristles or flights 203 or the equivalent and guide 210 without simultaneously contacting both. In this embodiment, this spacing is fixed, thereby simplifying the construction and operation of this seed conveyor and orientation assembly 200. In some alternative embodiments, this spacing is adjustable to allow an operator to adjust the apparatus to constrain different types, geometries, or dimensions of seed. In further alternative embodiments, a spring is provided to resiliently hold endless belt 202 against guide 210. In yet further alternative embodiments, a sensor and automatically adjustable drive, for exemplary and non-limiting purposes such as a screw drive, are provided to automatically apply an appropriate force pressing endless belt 202 against guide 210.

[0121] In some alternative embodiments, a small amount of agitation may be desired within guide 210. In such embodiments, bumps or other surface irregularities may be provided that agitate seed 106 passing in contact therewith.Atty. Dkt. 24186WO

[0122] When the length and geometry of conveyor belt 201 permits, in some embodiments the spacing of endless belt 202 from guide 210 can be set to disable contact therebetween, either manually or with automatic spacing control. In the event of a manually or automatically detected failure within seed conveyor and orientation assembly 200, such as a failure of endless belt 202 to move or rotate, separating endless belt 202 from guide 210 to allow seeds 106 to pass therebetween will allow seeds to still pass through seed conveyor and orientation assembly 200 and be planted in the earth.

[0123] In addition to proper spacing, the stiffness and fill density of brush bristles 203 is selected to prevent individual seeds from slipping between adjacent brush bristles and thereby potentially losing contact with guide 210. In those alternative embodiments that incorporate a resilient or elastomeric material such as a foam rubber or elastic sheet, the density or elasticity of the foam rubber or elastic sheet in the aforementioned alternative embodiments will similarly be selected to ensure that individual seeds 106 simultaneously contact both endless belt 202 and guide 210. This combination provides instantaneous contact and stabilization between the seed and guide 210.

[0124] In some alternative embodiments using flights such as disclosed in FIGs. 2C 5A, 5D, and 10B of the aforementioned PCT Publication WO2013 / 049198, seed 106 undergoes acceleration that includes the application of centrifugal force adjacent the end of guide 210 prior to release of seed 106 therefrom. In such embodiments, with an appropriate “V”-shaped geometry of guide 210 such as taught and illustrated herein, seed 106 may further undergo seed orientation.

[0125] While seed acceleration including centrifugal force is shown adjacent the seed exit in the aforementioned PCT Publication WO2013 / 049198, in yet further alternative embodiments other locations within conveyor belt 201 will be designed to provide this application of centrifugal force in combination with suitable geometry of guide 210. Conveyor belt 201 may be configured to include changes of conveyor direction at one or more locations along guide 210 intermediate between seed meter 128 and seed conveyor exit 230. For exemplary and non-limiting purpose, in some embodiments this is simply a continuously curved geometry in at least the seed transporting portion that more nearly resembles the outline of a circle, rather than that of the numeral “0" illustrated in FIG. 3.

[0126] FIG. 6 illustrates another alternative embodiment, where conveyor belt 201 which is in the general shape of the numeral “0" has been replaced by a twisted conveyor belt 206. As mayAtty. Dkt. 24186WO be garnered from the illustration of twisted conveyor belt 206, this belt has been twisted in the general manner of a pretzel, converting conveyor belt 201 to twisted conveyor belt 206 by providing an approximate 180 degree twist between the top and bottom of the conveyor belt. The particular degree of twist may vary widely from and be greater or less than the approximate 180 degree twist shown, the extent which will be determined by a reasonably skilled designer upon a review of the present disclosure and consideration of the desired centrifugal force and other related factors. This twist means that a seed traversing twisted conveyor belt 206 from seed meter 128 to seed conveyor exit 230 will travel a helical path, essentially continuously undergoing the application of centrifugal force. In some embodiments, sliding surface 212 is additionally banked, such as in the manner described in U.S. Patent Application Publications 2020 / 0367425 and 2022 / 0192079.

[0127] In consideration thereof, and whether curved, twisted, or simply sufficiently curved adjacent seed conveyor exit 230, conveyor belt 201 may provide a desired degree of orientation within seed conveyor and orientation assembly 200 independent of seed orientation coil assembly 240. Consequently, in some of these alternative embodiments a designer will elect to eliminate seed orientation coil assembly 240. In other embodiments, a conveyor belt 201, 206 which provides seed orientation benefit will be further enhanced by the inclusion of seed orientation coil assembly 240. Such consideration and decisions will be made by a designer reasonably skilled in the art upon consideration of the teachings of the present disclosure.

[0128] As illustrated in FIG. 4, drive apparatus 204 and seed disc 131 rotate in opposite directions, clockwise and counterclockwise respectively. However, in alternative embodiments the position of seed conveyor and orientation assembly 200 may be flipped relative to seed disc 131, and in such embodiments the rotations of drive apparatus 204 and seed disc 131 may be in the same direction, such as clockwise. An example of such an arrangement and direction of rotation, further including flights instead of brush bristles 203, is shown in Figures 11 A- 1 IE of the aforementioned PCT Publication WO2013 / 049198 and described therein.

[0129] In one embodiment, the simplified cross-sectional view of FIG. 5 is taken on a horizontal plane. As illustrated therein, vertical plane 219 contains vertical seed drop axis 192 and is generally parallel with and offset from a vertical plane defined by a major surface of endless belt 202. Guide surface 210 has two surfaces, a guide wall 211 and sliding surface 212, that together form a “V”-shaped channel that opens toward endless central belt 202. Brush bristles or flightsAtty. Dkt. 24186WO203 track in this channel opening of guide surface 210. The guide wall angle 213 between vertical plane 219 and guide wall 211 is preferably greater than the sliding surface angle 214 between vertical plane 219 and sliding surface 212. In some embodiments, sliding surface angle 214 is 0 to 60 degrees, or 0 to 45 degrees, or about 45 degrees. Guide wall angle 213 is the supplementary angle to sliding surface angle 214 and an angle formed by small open space 216 such that all three angles form a straight line. As illustrated, seed 106 will in some embodiments align or be aligned through appropriate technique such that a major surface of seed 106 will slide upon sliding surface 212, while a minor surface of seed 106 will slide upon guide wall 211. A seed 106 traversing guide surface 210 is pressed into the intersection between guide wall 211 and sliding surface 212 by brush bristles or flights 203, leaving a small open space 216 between seed 106 and the base of the “V”-shaped channel opening, adjacent the intersection between guide wall 211 and sliding surface 212. Small open space 216 forms an angle of 80 to 95 degrees, or about 90 degrees, or an acute angle. While as illustrated and described FIG. 5 is taken on a horizontal plane, it will be understood that the travel of endless central belt 202 will in some embodiments and through parts of travel will run in a direction offset from a vertical path of travel. In such instance, a section view similar to FIG. 5 would also be offset from vertical, as would vertical plane 219. Consequently, it will be understood that the references herein to vertical and horizontal are only exemplary and as illustrated in FIGs. 4 and 5, and do not limit the invention solely thereto. In one embodiment, sliding surface angle is 45 degrees, guide wall angle is 45 degrees, and the angle formed by small open space 216 is 90 degrees.

[0130] The bristles or flights 203 in the embodiment as illustrated in FIGs. 4 and 5 do not extend all the way to the intersection between guide wall 211 and sliding surface 212, leaving this open space 216 open and unblocked through most or the entirety of guide surface 210. Nevertheless, in some alternative embodiments the bristles or flights 203 will extend all the way to the intersection between guide wall 211 and sliding surface 212.

[0131] When the bristles or flights 203 do not extend all the way to the intersection between guide wall 211 and sliding surface 212, air may naturally be drawn into open space 216 by virtue of the travel of conveyor belt 201 and seeds 106 transported therein. This air stream will in some embodiments provide assistance to seed orientation and travel into the earth. Nevertheless, in some alternative embodiments the air flow may be enhanced through the provision of air vents provided at suitable locations within guide 210 or otherwise adjacent to open space 216 toAtty. Dkt. 24186WO improve a transfer of air into the seed pathway. In other alternative embodiments, air may be injected into open space 216 or bristles or flights 203 at one or more suitable locations. When air is so injected, and if properly directed, this airfeed may serve as the air infeed into seed orientation coil assembly 240, such as taught by U.S. Patent Publication No.US2022 / 0192079A1. However air is introduced into and moved through open space 216, such air may in some embodiments also assist with the transport of undersized seeds, debris, and other matter from conveyor belt 201.

[0132] Most preferably, seed sliding surface 212 couples in a continuous and non-disruptive manner to seed riding surface 292. In like manner, guide wall 211 will in some embodiments couple in a continuous and non-disruptive manner to a similar guide wall adjacent to seed riding surface 292. This helps to insure that seed 106 passes from conveyor belt 201 into seed orientation coil assembly 240 in sliding contact with seed riding surface, most preferably free from bounce, tumbling, or the like.

[0133] The seed conveyor and orientation assembly 200 preferably also includes a backing plate 220 disposed to maintain the position of central belt 202 relative to guide surface 210. While not illustrated in simplified Figures 4 and 5, it will be understood that in many embodiments conveyor belt 201 will further include a housing surrounding and enclosing central belt 202 and bristles or flights 203.

[0218] FIG. 38 illustrates a front view of an example seed meter apparatus 3502 with a cover 3504 and a mask (not shown) that may be arranged with a seed disc 3512. The cross-section 40- 40 is illustrated in FIG. 39.

[0219] FIG. 39 illustrates an example cross-section 40-40 section of FIG. 38 of a seed meter apparatus 3902 with a cover 3904 and a mask 3909 that may be arranged with a seed disc 3912.

The seed disc 3912 may be disposed between the cover 3904 and the housing 3910. The seed disc 3912 may be disposed between theAtty. Dkt. 24186WO cover 3904 and the mask 3909. The mask 3909 may have a seed track cutout 3907. The drive shaft 3924 may be configured to extend through the housing 3910 to the seed disc 3912. As described herein, an arrangement with a seed disc disposed between a mask and a cover may provide for the fewer seeds from falling from the face of a seed meter, that may improve the productivity and / or efficiency of the seed planting device.

[0220] Referring to FIGs. 40 to FIG. 48, the seed meter 1100 includes a housing comprised of a vacuum cover 1110 and a seed housing 1105. As described further herein, the seed meter 1100 functions by selecting one seed at a time from seeds communicated into the seed housing 1105 and dispensing each seed through the seed exit 1180. A vacuum inlet 1115 is coupled to the vacuum cover 1110. Vacuum hoses or tubes (not shown) connect the vacuum inlet 1115 to a vacuum source (not shown) such as a vacuum impeller.

[0221] The seed housing 1105 includes pivots 1113 (FIG. 41) and tabs 1103 (FIG. 40). When assembled, the tabs 1103 extend through holes in the vacuum cover 1110 such that retaining springs 1108 (1108-1, 1108-2, etc.) may be biased against pivots 1113 (1113-1, 1113-2, etc.) and tabs 1103 (1103-1, 1103-2, 1103-3, etc.) to retain the seed housing 1105 in position against the vacuum cover 1110.

[0222] Referring to FIG. 41, the seed meter 1100 is shown with the vacuum cover 1110 and other components removed for clarity. A shaft 1183 is rotatably coupled to bearings 1184 (1184- 1, 1184-2, etc.).

[0223] Bearings 1184 are held in place by the vacuum cover 1110. A drive plate 1186 is coupled to and rotates with the shaft 1183. Drive plate 1186 is releasably coupled to a seed disc 1120. Seed disc 1120 includes apertures 1122 and preferably includes drive teeth 1121. In operation, the seed disc 1120 may be rotated by a driven gear (not shown) coupled to drive teeth 1121 (as described further herein) or by a driven shaft (not shown) coupled to an adapter 1185 (FIG. 41) mounted to the shaft 1183.

[0224] Referring to FIG. 42, the interior of the seed housing 2105 is shown with the seed disc 1220, drive shaft 1283 and drive plate 1186 removed. A brush 1112 is mounted to seed housing 1105 such that its bristles contact the seed-side surface of the seed disc 1120. A singulator 1130 is mounted to the seed housing 1105 which cooperates with the seed disc 1120 to singulate the seeds before they are dispensed through the seed exit 1180. The singulator preferably includes multiple singulator surfaces in contact with a seed side surface 1140 of the seed disc 1140.Atty. Dkt. 24186WO

[0225] Singulation performance improves with an increasing number of times that the seeds are contacted by the singulating lobes (not shown). It has been determined that superior singulation accuracy is achieved by bumping or agitating the seeds from both a top side (e.g., an outside radius of the apertures such as 1122) and a bottom side (e.g., an inside radius of the apertures 1122). For example, if a singulator is used that only bumps the seeds from the top side, then some seeds multiples may be able to “hang” on the very bottom of the aperture and would not be stripped or removed by the top singulator. Furthermore, it has been found that singulation can be best achieved when the seed is contacted three times from the top side of the apertures 757 relative to the path of travel and two times from the bottom side of the apertures 757.

[0226] Referring to FIG. 43 and FIG. 44, seeds are communicated into the seed meter 1100 beneath a baffle 1160 mounted to the seed housing 1105. A seed pool area 1150 (FIG. 43) is disposed horizontally adjacent to the seed disc 1120 near a bottom end of the seed housing 1105 for collection of seeds communicated into the seed meter.

[0227] The height of baffle 1160 may be adjusted along guides 1164 and 1166. The baffle 1160 is mounted to the seed housing 1105 by rivet 1162, which extends outside the seed housing 1105 (as best seen in FIG. 47) and may be moved vertically by the operator along a notched slot 1117 without disassembling the housing. Each notch in slot 1117 is sized to hold the rivet 1162 in place such that the operator can select the height of baffle 1160 by pushing the rivet up and down. As illustrated, visual indicators (e.g., numbers 1 through 4) may be located adjacent to the notches for positioning the rivet 1162 at corresponding heights of the baffle 1160 for ease of reference.

[0228] Referring to FIG. 44, FIG. 45, and FIG. 46, the singulator 1130 is releasably mounted to the seed housing 1105 so as to bias the singulator against the seed disc 1120 while allowing the singulator to "float" both axially and longitudinally with respect to the axis of rotation of the seed disc. The singulator is releasably coupled to an axial spring 1137 by attachment ears 1139. The axial spring 1137 is preferably made of a material (e.g., spring steel) which is elastically deformable. The axial spring 1137 is mounted to bosses 1142 (1142-1, 1142-2, etc.). The bosses 1142 are sized such that the singulator 1130 is biased against the face of the seed disc 1120 when the seed disc is in its normal position. Thus, when the seed disc 1120 is deflected axially away from the vacuum cover 1110, the tension in axial spring 1137 increases, allowing the singulator to remain in contact with the seed disc without interfering with the rotation of the seed disc.Atty. Dkt. 24186WOLikewise, when the seed disc is deflected axially toward the vacuum cover 1110, the tension in axial spring 1137 decreases such that the singulator remains in contact with the seed disc.

[0229] Radial spring 1111 is mounted to the seed housing 1105 such that in operation, the radial spring biases the singulator radially against the seed disc 1120 when the seed disc is in its normal position.

[0230] The singulator 1130 is easily replaceable with another singulator with a different lobe configurations for different seeds or if it is necessary to replace the singular due to wear on the singulator lobes. The singulator 1130 is removable by pulling it away from the axial spring 1137 with sufficient force that the attachment ears 1139 deflect away from each other sufficiently to release the base 1133. The attachment ears 1139 may also be deflected away from each other with one hand while pulling the singulator 1130 away from the axial spring 1137 with the other. Likewise, the singulator 1130 may be replaced by pressing the base 1133 of the singulator between the attachment ears 1139 (e.g., 1139-1, 1139-2, etc.) with sufficient force to cause the attachment ears to deflect away from each other to allow the base of the singulator to pass between them. To replace the singulator, the base 1133 may be pushed between the ears causing them to deflect away from one another before returning to the normal position in which the base of the singulator is again secured between the ears. In this way the singulator 1130 may be easily removed and replaced by hand without the use of tools and without removing or changing the location of axial spring 1137, which remains in the correct location to bias the singulator 1130 against the seed disc 1120 while allowing the singulator 1130 to "float" with deflections or deformations of the seed disc.

[0231] Referring to FIG. 48, the seed meter 1100 is illustrated with the seed housing 1105 and other components removed so that the singulator 1130 may be seen in its preferred location biased against the seed- side surface 1140 of the seed disc 1120. The seed-side surface 1140 is preferably normal to the axis of rotation of the seed disc 1120. The seed- side surface 1140 is also preferably substantially flat with the exception of cavities (not shown). A portion of the seed aperture path is adjacent to the seed pool area 1150. As the seed apertures 1122 turn past the seed pool area 1150 at the bottom of the seed housing 1105, a vacuum side of each seed aperture is placed in fluid communication with the vacuum source such that one or more seeds (not shown) become entrained over apertures 1122.

[0232] Again referring to FIG. 48, each cavity may have an inner sidewall 1242 and an outerAtty. Dkt. 24186WO sidewall 1240 located at distances Ri, Ro respectively from the center C (e.g., the central or rotational axis) of the disc. The difference between the radii Ro and Ri may be greater than the diameter of the seed apertures 1122. The radius Ro is preferably larger than the distance between the seed aperture and the center of the seed disc 1120. The radius Ro may be larger than the radius Ra between a distal end of said seed aperture 1122 and the center of the disc 1120. Seed singulation is described in PCT Application No. WO2012129442A and U.S. Patent No. USRE45412. As described herein, the singulator 1130 as mounted to the face of any seed disc as described herein may, via inducing a flipping moment or such, motivate a seed (not shown) along any aperture and / or seed path as described herein. The singulator 1130 as mounted to the face of any seed disc as described herein may, via inducing a flipping moment or such, motivate a seed (not shown) into an orientation (e.g., tip first, etc.) as the seed moves along any aperture and / or seed path as described herein.

[0233] The singulator 1130 is optional for singulating the seeds. Singulation may be achieved with mask 3609 alone, singulator 1130 alone, or a combination of singulator 1130 and mask 3609.

[0234] Referring to FIG. 17 to FIG. 48, a seed meter apparatus may comprise a seed disc. The seed disc may comprise one or more apertures. One or more, or each, of the one or more apertures may extend from a seed loading zone of the seed disc to a seed release zone of the seed disc. The seed meter apparatus may comprise a cover that may be disposed at least partially on the seed disc. The cover may comprise a seed track cutout. The seed track cutout may form a seed track path on the seed disc. The seed track cutout may expose one or more sections of at least some of the one or more apertures along the seed track path. The seed disc may be configured for rotational movement relative to the cover to motivate, at least in part, one or more seeds to travel along at least a portion of the seed track path.

[0235] In one or more scenarios, the apparatus may comprise a drive shaft and / or a gear teeth that may be in mechanical communication with the seed disc. The drive shaft and / or the gear teeth may be configured to rotate the seed disc relative to the cover to motivate, at least in part, one or more seeds to travel along at least a portion of the seed track path.

[0236] In one or more scenarios, the seed disc may comprise a center region and / or an outer circumferential region. In one or more scenarios, the seed disc may be configured such that the seed loading zone may be proximate to the center region, and the seed release zone may beAtty.
