The present disclosure generally relates to planters and to related methods of planting seeds.
This section provides background information related to the present disclosure which is not necessarily prior art.
Plant researchers often cultivate thousands or tens of thousands of small plots of numerous different types of seeds in order to test/analyze different genotypic and/or phenotypic traits of the seeds and/or selected treatments applied thereto. In so doing, fields can comprise multiple such plots, and each of the plots may be planted with different types of the seeds (in multiple different passes through the fields by planters). As an example, a plant researcher may plant, using a planter, a first plot in a given field with a first type of seeds in order to test/analyze the seeds. The plant researcher may then change the seed type at the planter to a second type of seeds and proceed in the field to plant the second type of seeds in order to test/analyze the seeds. In some instances, filler seeds, not intended to be tested by the plant researcher, may also be planted in the field (in still another pass through the filed by the planter), around the test plots of the first and second types of seeds, to provide a buffer between the different ones of the test plots in the field.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
Example embodiments of the present disclosure generally relate to planting units for planting plots of seeds in fields. In one such example embodiment, the planting unit is associated with a first seed storage unit configured to provide seeds to the planting unit and a second seed storage unit configured to provide seeds to the planting unit. The planting unit also includes a seed meter configured to plant seeds from the first seed storage unit and the second seed storage unit in a field, and a diverter unit coupled to the seed meter. The diverter, then, is configured to selectively direct seeds from the first seed storage unit and the second seed storage unit to the seed meter.
In another such example embodiment, a planter for planting multiple rows of seeds in a field includes multiple ones of the planting units.
Example embodiments of the present disclosure also generally relate to methods of planting seeds in fields using automated planting units. One example method includes delivering a first set of seeds from a seed storage unit to a seed meter of the planting unit through a diverter, along a first flow path of the diverter; dispensing one or more of the first set of seeds from the seed meter to the field; moving a gate of the diverter to block the first flow path; and delivering a second set of seeds from the seed storage unit to either the seed meter or a planting tube of the planting unit through the diverter, along a second flow path of the diverter, and dispensing one or more of said second set of seeds to the field.
Another example method is directed toward planting seeds in a field (e.g., mixed plots of seeds, etc.) using an automated planting unit. This example method includes delivering a first set of seeds to a seed meter of the planting unit (e.g., from a seed storage unit, etc.) through a diverter coupled to the seed meter, along a first flow path of the diverter; moving a gate of the diverter to block the first flow path; delivering a second set of seeds to the seed meter (e.g., from the same seed storage unit, from another seed storage unit, etc.) through the diverter, along a second flow path of the diverter; and dispensing one or more of said first and second sets of seeds to the field (e.g., as a mixed combination of the first and second sets of seeds, etc.).
Further, example embodiments of the present disclosure generally relate to diverters for use in planting units for planting seeds in fields. In one such example embodiment, a diverter includes a housing, a first port configured to receive seeds into the housing from a seed storage unit associated with the planting unit, a second port in fluid communication with the first port along a pathway defined by the housing where the second port is configured to deliver seeds out of the housing to a seed meter of the planting unit, and a third port in fluid communication with the first port along the pathway where the third port is configured to deliver seeds out of the housing to either the seed meter or a planting tube of the planting unit. The diverter unit also includes a gate disposed within the housing along the pathway, wherein the gate is configured to move relative to the housing to selectively block either the second port or the third port and whereby the seeds received into the housing through the first port are able to flow through the housing along the pathway to either the second port or the third port based on a position of the gate.
Further areas of applicability will become apparent from the description provided herein. The description and specific examples in this summary are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
Corresponding reference numerals indicate corresponding parts throughout the several views of the drawings.
In cassette planting systems (e.g., in systems that use electronically-mapped (or indexed), multi-population seed containers, etc.), planters are often operated, in accordance with predefined planting plans, to plant relatively small numbers of seeds from cassette storage units (or other seed storage units in which different types of seeds are still separately stored and indexed so that a particular location of the different types of seeds in the storage units is known (e.g., other seed storage units not necessarily requiring use of cassettes, etc.)) into relatively small plots in the fields (e.g., 15 to 30 plants (or more) per plot in strips ranging from about ten feet all the way up to a few hundred feet (e.g., for testing purposes, etc.), etc.) in order to test/analyze different genotypic and/or phenotypic traits of the seeds and/or selected treatments applied thereto. In certain circumstances, it may be desired to plant other seeds between and/or around the smaller plots (e.g., as buffers on the borders of the smaller plots, in alleys within and/or between the smaller plots, etc.). Such other seeds may include any desired seeds, for example, and without limitation, filler seeds that are not intended for testing, seeds that are intended to be tested for aspects other than the seeds in the smaller plots, seeds that are not in competition with the seeds in the smaller plots, seeds that are to be utilized for other purposes (e.g., erosion control, refuge, breaks, etc.), seeds that already have a predictable and/or proven performance record, etc. Typically, such other seeds are also included in the cassette storage units, or such other seeds may be planted in subsequent operations of the planter (e.g., after refilling the cassette storage units with the other seeds, etc.). As can be appreciated, in the former, maintaining the other seeds in the cassette storage units may use up substantial space with the seeds, leaving minimal/reduced space for the seeds actually intended for testing. And, in the later, the subsequent planting may inadvertently overlap on the smaller plots previously planted (potentially contaminating the plots with the other seeds) and/or may involve substantial additional time to perform/complete.
To accomplish such planting of seeds from the cassette storage units, the planters often include seed meters configured to dispense desired seeds from the cassette storage units into furrows created by the planters in the fields (e.g., in desired quantities, at desired rates, at desired spacing, etc.) (see, e.g., Applicant's co-owned U.S. Pat. No. 10,159,176, the entire disclosure of which is incorporated herein by reference). And, the seed meters typically include chambers for use in receiving the seeds into the seed meters (e.g., staging chambers, etc. to allow for quick planting of multiple different types of seeds received from the cassette storage units; etc.), chambers for use in planting the received seeds in the fields (e.g., planting chambers or metering chambers, etc.), and then chambers for use in emptying excess seeds from the seed meters when planting is complete for the given seeds (e.g., evacuation chambers, etc.).
In example embodiments of the systems and methods of the present disclosure, desired seeds for planting may uniquely be obtained either from the cassette storage units (broadly, first seed storage units) onboard the planters (or otherwise traveling with the planters and/or accessible to the planters) or from bulk storage units (broadly, second seed storage units) also onboard the planters (or otherwise traveling with the planters and/or accessible to the planters). In connection therewith, the cassette storage units of the planters include multiple cells of different types of seeds, for example, intended to be tested by plant researchers, etc. And, the bulk storage units then include additional seeds, for example, for planting between, around, etc. rows/plots of the seeds planted from the cassette storage units. As can be appreciated, by maintaining the additional seeds in the bulk storage units, apart from the seeds in the cassette storage units, no space is used up and/or wasted in the cassette storage units on the additional seeds, while the additional seeds are still available at the planter for planting. It should be appreciated that reference to the cassette storage units and the bulk storage units herein are not intended to limit the types of storage units that may be implemented as first and/or second seed storage units in the present disclosure.
With that said, in various embodiments, the systems and methods of the present disclosure generally enable seeds from any of the seed storage units associated with the planters to be planted “on the fly”, while the planters are moving through the fields (and when the planters reach the particular locations and/or cross into/over the particular locations). In connection therewith, it should be appreciated that the systems and methods herein are not limited to any particular configuration (and/or location) of the seed storage units providing the seeds to the planters, or the manners in which the seeds are ultimately delivered and planted. The seeds may originate from any desired location associated with the planters (be it onboard the planters or not), and then be planted.
For example, the systems and methods herein enable the seed meters of the planters to receive seeds from both the cassette storage units and the bulk storage units during planting operation (for planting in the field). In addition, the systems and methods herein facilitate seamless switching between planting seeds from the cassette storage units and planting the seeds from the bulk storage units. Further, in some implementations, in planting the seeds from the bulk storage units, the seeds may be delivered to the staging chambers of the seed meters or they may bypass the staging chambers and instead proceed directly (from the bulk storage units) to the metering chambers of the seed meters. In the later scenario, larger amounts of the seeds from the bulk storage units may be planted as desired, without first staging limited amounts of the seeds in the staging chambers of the seed meters (i.e., the seeds may bypass the staging chambers). What's more, in other implementations, the seeds from the cassette storage units and/or the seeds from the bulk storage units may bypass the seed meters altogether and be delivered to planting tubes to allow for desired planting spurts of the seeds (e.g., when planting plots on hills having variable elevations (i.e., hill plots), etc.) (e.g., two or more unsingulated seeds at substantially the same time (since the seeds bypass the seed meters), etc.). These bypass features may allow the planters to easily transition between, for example, a digital ag research configuration (whereby precise amounts of seeds from the cassette storage units and/or from the bulk storage units are received in the staging chambers of the seed meters and prepared for planting in particular plots) and a bulk planting configuration (whereby thousands of the seeds from the bulk storage units may be planted as desired around the seeds planted from the cassette storage units or whereby seeds from the cassette storage units may be planted in spurts, etc.). In general, though, it should again be appreciated that the features of the present disclosure facilitate movement of seeds from generally any seed storage units associated with the planters (regardless of the configurations of the storage units) to any other desired locations of the planters (e.g., one or more chambers of seed meters, planting tubes, etc.) for subsequently processing the seeds (be it planting the seeds, evacuating the seeds from the planters, etc.).
In various embodiments, the systems and methods of the present disclosure also include, and facilitate the operation of, fully-automated, GPS-guided planters having the features herein and capable of transitioning between, and planting of, different seeds within the cassette storage units and the seeds within the bulk storage units. In addition, the planters may be configured to effect such transitioning based on prescriptions of the planting plans, which describe particular configurations and locations of seeds that are to be planted in particular growing areas. Alternatively, the planters may be configured to effect such transitioning based on data provided by sensors located onboard the planters (or sensors apart from the planters (e.g., associated with drones flying over the fields, etc.) but in communication therewith, or from artificial intelligence remote from the planters but that have recently analyzed the fields to reveal that new planting plans (e.g., revisions to the planting plans current in effect, etc.) for the fields would be better for breeding pipelines, etc.), whereby the data may relate to soil conditions, temperature conditions, plot geography, etc. and may be used to determine particular seeds to be planted at particular locations in the fields “on the fly”, while the planters are moving through the fields (and when the planters reach the particular locations and/or cross into/over the particular locations).
Example embodiments will now be described more fully with reference to the accompanying drawings. The description and specific examples included herein are intended for purposes of illustration only and are not intended to limit the scope of the present disclosure.
The planter 100 generally includes a frame 104 supporting multiple planting units 106. And, the planting units 106 are configured to plant seeds as desired in the field/plot. In the illustrated embodiment, the planting units 106 are configured to plant any desired types of seeds (e.g., and without limitation, corn, soybeans, etc.) or dispense any other small objects (i.e., the planter 100 and the description herein should not be construed as limited to any particular type of seeds or to seeds in general). In various embodiments, one or more of the planting units 106 may be adapted to handle more than one type of seed, or may be quickly converted to handle different types of seeds (such that different ones of the planting units 106 may plant different seeds and/or such that the planting units 106 may switch between types of seeds being planting, for example, while planting (e.g., “on the fly”, without stopping, etc.)). Also in the illustrated embodiment, the planter 100 includes sixteen planting units 106. However, in other embodiments, the planter 100 may include more than or fewer than sixteen planting units within the scope of the present disclosure (e.g., four planting units such as illustrated in
The planting units 106 of the planter 100 may also be adjustable relative to the frame 104. For example, the planting units 106 may be configured to slide laterally along the frame 104 (e.g., via one or more actuators, etc.) to thereby change spacing between the planting units 106 (e.g., to allow for compact travel, to adjust spacing between the planting units 106 during planting (e.g., on the fly, etc.) to thereby adjust spacing between rows of planted seeds during planting, etc.) and/or collapsed or folded relative to the frame 104 to a width such that it can travel on conventional roads (see, e.g., Applicant's co-owned U.S. Pat. Nos. 7,673,572, 7,775,167, and 9,635,799, the entire disclosures of which are each incorporated herein by reference; etc.). However, such adjustability is not required in all embodiments.
A control system 108 is provided in communication with the planter 100 and the planting units 106 thereof, and is configured to control one or more operations of the planter 100 (and/or the tractor 102) described herein (e.g., such that in some embodiments the planter 100 may be fully automated, may operate without human intervention, etc.). In the illustrated embodiment, the control system 108 is disposed in the tractor 102. However, in other embodiments, the control system 108 may be located otherwise, for example, on the planter 100, remote from the planter 100 and tractor 102 (for remote operation thereof), etc. In connection therewith, the control system 108 may include (and/or be associated with) a global positioning system (GPS) receiver 110, whereby the control system 108 and the GPS receiver 110 may be configured to control operation of the tractor 102 to move through the field/plot (e.g., to move through the field/plot along a desired path, to move to desired locations in the field/plot, etc.), and to control operation of the planting units 106 of the planter 100 to plant seeds in the field/plot (e.g., to plant desired seeds in the field/plot, to plant desired seeds in desired locations in the field/plot, to transition between different seeds stored onboard the planter 100 to effect such planting on the fly, to plant seeds at a desired rate (and/or change the rate on the fly), to plant seeds at a desired row spacing (and/or change the row spacing on the fly), etc.). With that said, it should be appreciated that the planter 100 may be fully automated in various embodiments, as described above. However, in other embodiments, the planter 100 may be utilized with manual-packet planting systems while still implementing one or more of the features described herein.

The first and second seed storage units 222, 224 of the planting unit 206 will be described next with reference to
With additional reference to
As described above, the seed rack 226 includes the multiple cells 227 configured to hold the seed receptacles. Each set of cells 227 is sized and adapted to retain a respective one of the seed receptacles. Particularly, each of the cells 227 may be associated with a particular x-y location within the seed rack 226. The locations of the seed receptacles in the cells 227 of the seed rack 226, then, can be mapped using the particular x-y locations of the corresponding sets of cells 227 (e.g., and stored in memory of a computing device associated with the planter 200 (see, e.g.,
The seed rack 226 also includes a cap 232 (e.g., a sluice plate, etc.) configured to position (e.g., slidably, etc.) over the cells 227, thereby inhibiting the seed receptacles (and the seeds therein) from prematurely sliding out of the cells 227 (e.g., when the seed rack 226 is inverted, etc.). That said, when the seed rack 226 is loaded in the first seed storage unit 222 (within frame 248 thereof), the cap 232 is generally facing downward (and is located adjacent the funnel 229). For example, to initially position the seed rack 226 in the first seed storage unit 222, the first seed storage unit 222 may be rotated away from the planting unit (
In other embodiments, the first seed storage unit 222 may include a switching system configured to selectively move one or more of the seed receptacles in the seed rack 226 to a position over the funnel 229 (when desired to release seeds therefrom for planting). In such embodiments, the seed rack 226 (or a portion thereof) may be moveable within the first seed storage unit 222 to effect such positioning of the desired seed receptacles. In addition, in still other embodiments, the first seed storage unit 222 may be associated with a vehicle separate from the planter 200 but that may move with the planter 200 and deliver seeds to the planting units 206 via conduits, etc. Further, it is again noted that the first seed storage unit 222 may include, and may be configured to accommodate, any desired arrangement of seeds whereby different sets of seeds are separately stored and indexed so that locations of the sets of seeds are known or available (e.g., electronically-mapped, multi-population seed containers (or receptacles), etc.).
As shown now in
In the illustrated embodiment, the nest 238 of the second seed storage unit 224 includes first and second sluice plates 241, 242 (e.g., double slide gates, etc.) each configured to selectively move (in a coordinated manner) between a closed position, in which the plates 241, 242 inhibit seeds S from leaving the container 236, and an open position, in which the plates 241, 242 allow the seeds S to flow (e.g., thereby providing a two-stage escapement mechanism, etc.) (broadly, means for portioning the seeds from the container 236). In connection therewith, the nest 238 includes corresponding first and second actuators 243, 244 (e.g., pneumatic cylinders, hydraulic cylinders, other known mechanical actuators, etc.) configured (via communication with the control system 208 associated with the planter 200) to move the respective sluice plates 241, 242 between the closed and open positions.
In particular, in an example operation of the container 236 and nest 238 (via communication of the control system 208 with the actuators 243, 244 of the nest 238), when the first and second sluice plates 241, 242 are in the closed position, the first sluice plate 241 inhibits/blocks movement of seeds S from out of the container 236 (
With that said, it should be appreciated that the staging cavity 247 of the container 236 may hold any desired number (or volume) of seeds released from the container 236, prior to directing the seeds to the seed meter 220 (e.g., about 100 seeds, about 50 seeds, about 1,000 seeds, etc.). In addition, in various embodiments, the first and second actuators 243, 244 of the nest 238 may be configured to move the first and second sluice plates 241, 242 to the open position at the same time, to allow direct flow of the seeds from the container 236 to the seed meter 220 (without first portioning the seeds in the staging cavity 247). As can be appreciated, this may be advantageous when planting large plots using the seeds from the second seed storage unit 224. In addition, it should be also appreciated that the container 236 may be configured to hold any desired type of seeds and/or any desired number of seeds. For example, the container 236 may be configured to hold hundreds, thousands, billions or more seeds. As such, the planter 200 may be capable of planting plots with the same seeds (e.g., from the first seed storage unit 222 for subsequent testing, etc.), fill in borders of the plots with seeds from the second seed storage unit 224, and then continue with additional seeds from the first seed storage unit 222, as desired, without stopping and/or without leaving unplanted areas, bare areas, etc.
With additional reference to
It should also be appreciated that the second seed storage unit 224 (i.e., the bulk seed storage unit) may include other configurations (e.g., other than the container 236 and the nest 238, etc.) in other embodiments, and may dispense and/or release seeds in other manners. For example, the second seed storage unit 224 may include a container 436 and a nest 438 as illustrated in
Referring now to
The seed handler portion 250 of the seed meter 220 includes a housing 252, and a drum 253 disposed within the housing 252. The drum 253 includes multiple seed pockets 254 (
As best shown in
In the illustrated embodiment, the drum 253 is configured to rotate within the housing 252 in increments of about sixty degrees, from one station/position to a next station/position, to account for the six seed pockets 254. In other embodiments, however, the drum 253 may be configured to rotate in other increments, for example, based on a number of seed pockets included in the drum 253, a number and/or location of desired positions of the drum 253 within the seed meter 220, a number and/or location of desired chambers within the seed meter 220, etc.
With continued reference to
It should be appreciated that other seed meters may be used with the planter 200 (and the planting units 206 thereof) within the scope of the present disclosure. In connection therewith, the seed meters may include/define any desired number and/or configuration of chambers (i.e., the particular number and arrangement of chambers described herein for the seed meter 220 should not be considered a limiting feature of the present disclosure). For example, seed meters having a single planting chamber may be used, whereby seeds from the first and second seed storage units 222, 224 may be delivered to the single chamber (or may bypass the chamber all together and be delivered directly to the planting tube 266), as desired, by way of the teachings herein. Similarly, seed meters having more than one chamber (i.e., a planting chamber and at least one additional chamber) may be used, again whereby seeds from the first and second seed storage units 222, 224 may be delivered to select ones of the particular chambers (or may bypass the chambers all together), as desired, by way of the teachings herein.
With reference to
With continued reference to
Based on this unique construction of the diverter 273, in the illustrated embodiment, upon receipt of the seeds from either of the first and second seed storage units 222, 224 (via the delivery funnel 271 and the first port 281), the diverter 273 is configured to selectively deliver the seeds to either the staging chamber 257 of the seed meter 220 (via the staging inlet 260) or the planting chamber 258 of the seed meter 220 (via the planting inlet 261). For instance, in the illustrated embodiment, the first port 281 of the diverter 273 is coupled to the delivery funnel 271 for receiving seeds from both the first and second seed storage units 222, 224. In addition, the second port 282 of the diverter 273 is coupled to the staging inlet 260 of the seed meter 220 at the staging chamber 257, and the third port 283 is coupled to the planting inlet 261 of the seed meter 220 at the planting chamber 258 (see,
As described, the illustrated diverter 273 includes the three ports 281-283. In various other embodiments, the diverter 273 may include fewer than three ports or more than three ports. For example, in one exemplary embodiment, the diverter 273 may include the first port 281 coupled to the first and second seed storage units 222, 224 (as described above). The diverter 273 may then include the second and third ports 282, 283 coupled to the staging chamber 257 and the planting chamber 258 (as described above). Then, in this embodiment, the diverter 273 may further include another port coupled to the evacuation chamber 259 (e.g., for clearing seeds from one or more receptacles of the first seed storage unit 222, for clearing seeds from the container 236 of the second seed storage unit 224, etc.) and/or another port coupled directly to the planting tube 266 (bypassing the seed meter 220) (e.g., for facilitating planting spurts of the seeds on hill plots, etc.). In this manner, the diverter 273 is configured to direct seeds from any of the storage units 222, 224 (or from any other storage unit(s) potentially used with the planter 200 through communication of the other storage unit(s) with the diverter 273 as described herein) to any desired destination at the planting unit 206 for subsequently processing the seeds (be it the seed meter 220 or the planting tube 266, etc.).
While the diverter 273 of the seed transport system 270 is described herein as including the gate 279 to selectively direct seeds through the diverter 273, it should be appreciated that other means may be used in other embodiments to similarly direct the seeds. For example, in at least one embodiment, forced air (via an air nozzle similar to nozzle 374) may be used to direct seeds through the diverter 273 instead of the gate 279. In such embodiments, a puff or surge of air from the air nozzle may be applied at about a ninety-degree angle relative to the path of the seed to thereby push the seed toward the desired one of the ports 282, 283.
An example operation of the planter 200 will be described next. Initially, the seed rack 226 for each of the planting units 206 is loaded with seed receptacles filled with selected seeds (e.g., desired seeds to be analyzed/tested, etc.). This may be done on-site where the seeds are to be planted, or off-site at a location remote from where the seeds are to be planted. In either case, once all of the desired seed receptacles are loaded into the cells 227 of the seed rack 226, the cap 232 of the seed rack 226 is installed generally over the seed receptacles (if not already in such position). And then, at the location where the seeds are to be planted (or prior), the seed rack 226 is positioned in the first seed storage unit 222 of the given planting unit 206 on the indexer 228 (e.g., generally upside down such that the cap 232 is disposed adjacent the queue 223 and funnel 229 of the first seed storage unit 222 and the delivery funnel 271 of the seed transport system 270, with the doors 225 generally inhibiting the seeds from moving out of the queue 223; etc.). Similarly, the container 236 of the second seed storage unit 224 is loaded with selected seeds (again, either on-site or off-site), and then, at the location where the seeds are to be planted (or prior), is positioned in the second seed storage unit 224 of the given planting unit 206 (e.g., such that the spout 239 of the container 236 is in communication with the nest 238, etc.).
Once the desired seeds are loaded in each of the planting units 206 of the planter 200, the planter 200 is then positioned in a field in preparation for traversing the field to plant plots of the different kinds of the seeds (from the first and second seed storage units 222, 224 of each of the planting units 206). In so doing, in this example, the control system 208 associated with the planter 200 is configured to operate the first and second seed storage units 222, 224 in conjunction with the diverter 273 and the seed meter 220 to plant a particular combination of the seeds from the first seed storage unit 222 and the second seed storage unit 224 in a plot (e.g., in accordance with a planting plan, etc.).
With that said, to initiate the planting operation in this example (as the planter 200 begins moving), the control system 208 is configured (for a given one of the planting units 206) to incrementally, or stepwise, rotate the drum 253 of the seed meter 220, relative to the housing 252 (in a suitable manner, for example, via motor 289), and position the upper opening 255 of a first seed pocket 254 adjacent the staging inlet 260 (e.g., within the staging chamber 257 and in a seed loading position, etc.). In addition, the control system 208 is configured to actuate a select one of the doors 225 of the first seed storage unit 222 to thereby release desired seeds (e.g., a desired set of seeds, etc.) from the queue 223 to the funnel 229 (in accordance with the planting plan, in accordance with other data provided to the planter 200, etc.) (see, also,
The control system 208 is configured to next rotate the drum 253 and position the first seed pocket 254 (with the seeds disposed therein) adjacent the seed disc 263 of the seed separator portion 251 of the seed meter 220 (within the planting chamber 258 in a seed planting position, etc.). Here, the lower opening 256 of the first seed pocket 254 is disposed in fluid communication with the apertures 264 of the seed disc 263, through the extraction window 290, and the seeds fall (e.g., via gravity, forced air, etc.) to the lower opening 256 where they are presented (through the extraction window 290) to the seed disc 263 (e.g., the seeds slide into contact with the seed disc 263, etc.). In turn, the control system 208 is configured to rotate the seed disc 263 and move each of the apertures 264 through the extraction window 290 and past the lower opening 256 of the first seed pocket 254. In this manner, seeds from the first seed pocket 254 are captured by the apertures 264 (e.g., the seeds are drawn to the apertures 264 via vacuum, etc.) and are rotated, by the seed disc 263, from the extraction window 290 to the exit chute 265 where they are dislodged from the apertures 290 via a wiper 291. The dislodged seeds then fall through the planting tube 266 and are planted in a furrow created by the planting unit 206.
The rotation of the first seed pocket 254 of the drum 253 from the staging chamber 257 of the seed meter 220 to the planting chamber 258 (i.e., to the position adjacent the seed disc 263) also positions a subsequent one of the seed pockets 254, i.e., a second seed pocket 254, adjacent the staging inlet 260 (e.g., in the staging chamber 257, etc.). In this example, the planting plan requires seed from the bulk supply be planted next (adjacent the plot just planted). As such, the control system 208 is configured to actuate the sluice plates 241, 242 of the second seed storage unit 224 (as generally described above) to thereby release seeds from the container 236 to the delivery tube 272 of the seed transport system 270 (via the outlet 231 of the nest 238) (see, also,
When the first seed pocket 254 of the drum 253 moves to the planting chamber 258 (as described above), a level sensor 292 (e.g., an ultrasonic level sensor, etc.) (
In this manner, the planning of the seeds for the given plot is not interrupted, even though additional seeds are required to complete the planting. In addition, by delivery of the subsequent seeds directly to the planting chamber 258 of the seed meter 220 (as opposed to the staging chamber 257), filling of the second pocket 254 of the drum 253 with the seeds from the bulk supply, as described above (based on the given planting plan in this example), is not delayed. In other words, such redirection of the subsequent seeds (and bypass of the staging chamber) facilitates and preserves the sequential operation of the seed meter 220 based on the given planting plan, particularly when it is determined that additional seeds are required for planting at any given time.
Next in this example, once the stipulated number of seeds are parsed from the first seed pocket 254 by the seed disc 263 to complete the given plot, the control system 208 is configured to rotate the drum 253 and position the first seed pocket 254 in the evacuation chamber 259 of the seed meter 220 (e.g., in an evacuation position, etc.). Here, the upper opening 255 of the first seed pocket 254 is disposed adjacent the evacuation nozzle 267 (such that the first seed pocket 254 is in communication with the evacuation nozzle 267 via the evacuation chamber 259), and any seeds remaining in the first seed pocket 254 are removed (e.g., by vacuum, gravity, forced air, combinations thereof, etc.) through the evacuation nozzle 267 (e.g., to an evacuation receptacle, etc.). In so doing, the drum 253 moves through a wiping position generally between the planting chamber 258 and the evacuation chamber 259, where the wiper 291 of the seed pocket 254 is configured to dislodge any excess seeds, as still entrained by the seed disc 263, back into the first seed pocket 254 (for removal).
This movement of the first seed pocket 254 of the drum 253 to the evacuation chamber 259 further positions a subsequent one of the seed pockets 254, i.e., a third seed pocket 254, in the staging chamber 257. And, in this example (according to the planting plan), seeds from another seed receptacle in the first seed storage unit 222 are released to the staging chamber 257 of the seed meter 220, for receipt in the third seed pocket 254 (in the same manner as described above). Further, the second seed pocket 254 moves to the planting chamber 258, whereby the seeds from the bulk supply contained in the second seed pocket 254 are presented to the seed disc 263 (in the same manner as described above) for planting. Again, the level sensor 292 is configured to monitor the level of the seeds in the planting chamber 258 and, if the seed level falls below the predefined level, the level sensor 292 is configured to notify the control system 208 whereby the control system 208 can direct additional seeds from the second seed storage unit 224 to the planting chamber 258 for planting. In particular, when such a notification is received from the level sensor 292 with regard to the seeds from the bulk supply, the control system 208 is configured to actuate the sluice plates 241, 242 of the container 236 to thereby release additional seeds from the container 236 to the delivery tube 272. In turn, the delivery tube 272 directs the seeds to the delivery funnel 271, which then delivers the seeds to the diverter 273. Here, though, because the planting operation has already started, and because the subsequent seeds are needed to continue/complete the current planting operation, the control system 208 is configured to position the gate 279 of the diverter 273 to block access (and a corresponding path) to the second port 282 along the flow route 285. As such, the subsequent seeds from the bulk supply pass through the diverter 273, along the flow route 285, from the first port 281 to the third port 283, where they then move directly into the planting chamber 258 of the seed meter 220 (bypassing the staging chamber 257).
The above operation of the planter 200 continues for the given planting unit 206 until the planting plan is complete (with continued rotation of the drum 253 moving the various seed pockets 254, one by one, through each of the stations of the seed meter 220, as appropriate). In addition, it should be appreciated that the above operation similarly applies to each of the other planting units 206 of the planter 200. Accordingly, as the planter 200 traverses across the field, each of the planting units 206 can independently control (and independently change) the kind and/or rate and/or row spacing of seeds dispensed by its seed meter 220 and planted in the field (e.g., one of the planting units 206 may plant seeds from the first seed storage unit 222 while, at the same time, an adjacent one of the planting units 206 may plant seeds from the second seed storage unit 224; etc.).
Also in the above planting operation, the control system 208 may utilize GPS data to effect one or more of the given operations. For example, the control system 208 may compare GPS-reported locations of the planter 200 to a map associated with the planting plan in order to determine the particular seeds to be planted in and/or around a given plot, and in order to determine boundary locations at which the drum 253 of the seed meter 220 is to be operated to change the types of seeds being planted. In addition, in some embodiments, operator inputs may also, or alternatively, be used to determine the particular seeds to be planted and the locations for such planting. Or, sensors associated with (e.g., mounted to and/or otherwise in communication with, etc.) the planter 200 (or artificial intelligence (and related data) provided to the planter 200 from one or more remote sources) may be used to determine the particular seeds to be planted based on sensed field conditions at the given location of the planter 200, etc. Further, in various embodiments, the control system 208 may be configured to command the seed meter 220 to drive the seed disc 263 either at a constant rate or at a rate determined by comparing a GPS-reported location of the planter 200 to the map associated with the planting plan. Such GPS-reported locations may also be used by the control system 208 to determine proper spacing between the planting units 206 of the planter 200 (whereby the spacing may be adjusted by moving one or more of the planting units 206 along the frame 204, etc.).
As an alternative to the above planting operation, when the planting plan (or other communication with the planter 200) requires seeds from the bulk supply to be planted, the control system 208 may be configured (at the outset of planting the seeds from the bulk supply) to direct the seeds straight to the planting chamber 258 of the seed meter 220, instead of the staging chamber 257. In this alternative, then, only seeds from the first seed storage unit 222 are received in the seed pockets 254 of the drum 253 at the staging chamber 257 (in other words, in this alternative, only the seeds from the first seed storage unit 222 are staged for planting).
In particular, and as generally described above, once the stipulated number of seeds from the first seed storage unit 222 are parsed from the first seed pocket 254 by the seed disc 263, the control system 208 is configured to rotate the drum 253 and position the first seed pocket 254 in the evacuation chamber 259 of the seed meter 220. In so doing, the drum 253 moves through the wiping position generally between the planting chamber 258 and the evacuation chamber 259, where the wiper 291 of the seed pocket 254 dislodges any excess seeds still entrained by the seed disc 263 back into the first seed pocket 254 (for removal). At this position, the control system 208 may be configured to stop the drum 253 and hold the first seed pocket 254 in the wiping position. Then, based on the planting plan (or other communication to the planter 200) requiring seeds from the bulk supply be planted next, the control system 208 may be configured to actuate the sluice plates 241, 242 of the second seed storage unit 224 (as generally described above) to thereby cause the container 236 to release seeds to the delivery tube 272 of the seed transport system 270. In turn, the delivery tube 272 directs the seeds to the delivery funnel 271, which then delivers the seeds to the diverter 273. Here, though, the control system 208 is configured to position the gate 279 in the diverter 273 to block access (and a corresponding path) to the second port 282 along the flow route 285. As such, the seeds pass through the diverter 273, along the flow route 285, from the first port 281 to the third port 283, where they then move directly into the planting chamber 258 of the seed meter 220. The seeds from the bulk supply may then be planted, through operation of the seed disc 263 (as described above), without actual staging of the seeds.
As still another alternative to the above planting operation(s), when the planting plan (or other communication to the planter 200) requires seeds from either of the first or second seed storage units 222, 224 to be planted in spurts, for example, to plant seeds on hill plots (e.g., two or more unsingulated seeds at substantially the same time, etc.), the control system 208 may be configured to direct the seeds straight to the planting tube 266 (via a port of the diverter 273 and suitable conduit), instead of to the seed meter 220 (whereby the seeds are not singulated by the seed meter 220).
In various embodiments, the seed meter 220 may further include one or more pre-singulators, teeth, wedges, etc. located in the path of the seed disc 263 (e.g., along the drum 253, etc.) to remove (or dislodge) seeds from the seed disc 263, for example, when multiple seeds are captured by a single one of the apertures 264. In so doing, the extra seeds may fall back into the given seed pocket 254 of the drum 253 (such that only one seed remains entrained on each respective aperture 264 of the seed disc 263), whereby they may be subsequently captured by the seed disc 263 (and delivered for planting). Or, the dislodged seeds may fall back into a bin associated with the seed pocket 254 (and may then be removed from the seed meter 220 when the seed pocket 254 moves into position to evacuate unused seeds therefrom.
In some embodiments, planting units may be modified to include the seed meter 220 and the diverter 273 of the present disclosure (e.g., existing cassette planters, etc.). In such planting units, a portion of a frame for supporting the seed meter 220 may need to be removed in order to accommodate the diverter 273. In such embodiments, in anticipation of such modification, the portion of the frame of the planting units to be removed may be perforated to allow for easy removal.
As described above, the planter 200 (and the various components and/or operations thereof) may be controlled (and/or coordinated) by the control system 208 (broadly, a computing device). In connection therewith,
The second seed storage unit 324 of this embodiment is substantially similar to the second seed storage unit 224 described above. For example, the storage unit 324 of this embodiment again generally includes a container 336 configured to hold the bulk supply of seeds therein, and a support 337 configured to releasably hold the container 336 on the planting unit 206. In particular, the support 337 includes a nest 338 configured to receive a dispensing spout 339 of the container 336 (when the container 336 is coupled thereto) and a moveable brace 340 configured to secure/retain the container 336 in the support 337. As such, the container 336 may be selectively removed from the support 337 (via pivoting movement of the brace 340) in order to receive the bulk supply of seeds therein, and then, once filled, re-coupled to the support 337 in the manner described above for the container 236. Seeds may then also be dispensed from the container 336 in the same manner described above for the container 236 (e.g., via selective activation of sluice plates 341, 342 of the nest 338, etc.).
In this embodiment, though, as shown in
As best shown in
Based on this unique construction of the diverter 373, in the illustrated embodiment, upon receipt of the seeds from the first and second seed storage units 222, 324 (via the corresponding one of the first and fourth ports 381, 384), the diverter 373 is configured to selectively deliver the seeds to either the staging chamber 257 of the seed meter 220 (via the staging inlet 260) or the planting chamber 258 of the seed meter 220 (via the planting inlet 261). For instance, in the illustrated embodiment, the first port 381 of the diverter 373 is coupled to the delivery funnel 371 for receiving seeds from the first seed storage unit 222 and the fourth port 384 is coupled to the delivery tube 372 for receiving seeds from the second seed storage unit 324. In addition, the second port 382 of the diverter 373 is coupled to the staging inlet 260 of the seed meter 220 at the staging chamber 257, and the third port 383 is coupled to the planting inlet 261 of the seed meter 220 at the planting chamber 258. Thus, based on the positioning of the gates 379, 380 within the diverter 373 (as described above), seeds can be selectively delivered from the first and second seed storage units 222, 324 through the diverter 373 to the desired one of the chambers 257, 258 of the seed meter 220. With that said, it should be appreciated that the second and third ports 382, 383 of the diverter 373 may be coupled to other chambers of the seed meter 220 as desired. For example, one of the second and third ports 382, 383 may be coupled to the evacuation chamber 259 to allow for clearing the system of seeds if needed. Similarly, one of the second and third ports 382, 383 (or a an additional port of the diverter 373) may be coupled directly to the planting tube 266 of the planting unit 206 to allow for quick planting of seeds (without metering) for planting seeds on hill plots, etc.
As described, the illustrated diverter 373 includes the four ports 381-384. In various other embodiments, the diverter 373 may include fewer than four ports or more than four ports. For example, in one exemplary embodiment, the diverter 373 may include the first and fourth ports 381, 384 coupled to the first and second seed storage units 222, 324 (as described above). The diverter 373 may then include the second and third ports 382, 383 coupled to the staging chamber 257 and the planting chamber 258 (as described above). Then, in this embodiment, the diverter 373 may further include a port coupled to the evacuation chamber 259 (e.g., for clearing seeds from one or more receptacles of the first seed storage unit 222, for clearing seeds from the container 336 of the second seed storage unit 324, etc.) and/or a port coupled directly to the planting tube 266 (bypassing the seed meter 220) (e.g., for facilitating planting spurts of the seeds on hill plots, etc.). In this manner, the diverter 373 is configured to direct seeds from any of the storage units 222, 324 (or from any other storage unit(s) potentially used with the planter 200 and/or planting unit 206) to any desired destination at the planting unit 206 for subsequently processing the seeds (be it to the seed meter 220 or the planting tube 266, etc.).
Again, while the diverter 373 of this embodiment is described as including the gates 379, 380 to selectively direct seeds through the diverter 373, it should be appreciated that other means may be used in other embodiments to similarly direct the seeds. For example, in at least one embodiment, forced air (via air nozzles similar to nozzle 374) may be used to direct seeds through the diverter 373 instead of (or in place of) the gates 379, 380 (e.g., where each of the gates may be replaced by an air nozzle, etc.). In such embodiments, a puff or surge of air from the air nozzles may be applied at about a ninety-degree angle relative to the path of the seeds to thereby push the seeds toward the desired one of the ports 382, 383.
In operation of the planter 200 (which is substantially similar to the operation described above), the seed rack 226 for each of the planting units 206 is again loaded with seed receptacles filled with selected seeds. And, once all of the desired seed receptacles are loaded, the seed rack 226 is positioned in the first seed storage unit 222 of the planting unit 206 (on the indexer 228). Similarly, the container 336 of the second seed storage unit 324 is loaded with selected seeds (again, either on-site or off-site), and then, at the location where the seeds are to be planted (or prior), is positioned in the second seed storage unit 324 of the given planting unit 206 via selective pivoting movement of the brace 340 (e.g., such that the spout 339 of the container 336 is in communication with the nest 338, etc.).
Once the desired seeds are loaded, the planter 200 (and planting unit 206) is/are then positioned in a field in preparation for traversing the field to plant plots of the different kinds of the seeds (from the first and second seed storage units 222, 324 of each of the planting units 206). In so doing, in this example, the control system 208 associated with the planter 200 is configured to operate the first and second seed storage units 222, 324 in conjunction with the diverter 373 and the seed meter 220 to plant a particular combination of the seeds from the first seed storage unit 222 and the second seed storage unit 324 in a plot (e.g., in accordance with a planting plan, etc.).
To initiate the planting operation in this example (as the planter 200 begins moving), the control system 208 is configured (for a given one of the planting units 206) to incrementally, or stepwise, rotate the drum 253 of the seed meter 220, relative to the housing 252 as described above, and position the upper opening 255 of a first seed pocket 254 adjacent the staging inlet 260 (e.g., within the staging chamber 257 and in a seed loading position, etc.). In addition, the control system 208 is configured to actuate a select one of the doors 225 of the first seed storage unit 222 to thereby release the desired seeds from the queue 223 to the funnel 229. In turn, the funnel 229 directs the seeds to the delivery funnel 371 and the first port 381 of the diverter 373 (see, also,
The control system 208 is configured to next rotate the drum 253 and position the first seed pocket 254 (with the seeds disposed therein) adjacent the seed disc 263 of the seed separator portion 251 of the seed meter 220 (within the planting chamber 258 in a seed planting position, etc.) in the manner described with reference to
At this point in the operation, with the first seed pocket 254 of the drum 253 positioned at the planting chamber 258, if the seed level in the pocket 254 falls below a predefined level or threshold, the level sensor 292 is configured to notify the control system 208 whereby the control system 208 is configured to direct additional seeds from the first seed storage unit 222 (of the same type being planted) to the planting chamber 258. In so doing, the desired (identified) seeds are released from the first seed storage unit 222 to the funnel 229, and the funnel 229 directs the seeds to the delivery funnel 371 and on to the diverter 373 (via the first port 381). Here, though, because the planting operation has already started, and because the subsequent seeds are needed to continue and complete the current planting operation, the control system 208 is configured to position the first gate 379, within the flow route 385 of the diverter 373, to block access (and a corresponding path) to the second port 382 (see, also,
Next in this example, once the stipulated number of seeds are parsed from the first seed pocket 254 by the seed disc 263 to complete the given plot, the control system 208 is configured to rotate the drum 253 and position the first seed pocket 254 in the evacuation chamber 259 of the seed meter 220 (e.g., in an evacuation position, etc.) to remove any remaining seeds therefrom. This movement further positions a subsequent one of the seed pockets 254, i.e., a third seed pocket 254, in the staging chamber 257. And, in this example (according to the planting plan), seeds from another seed receptacle in the first seed storage unit 222 are released to staging chamber 257 of the seed meter 220, for receipt in the third seed pocket 254 (in the same manner as described above). Further, the second seed pocket 254 moves to the planting chamber 258, whereby the seeds from the bulk supply contained in the second seed pocket 254 are presented to the seed disc 263 (in the same manner as described above) for planting. Again, the level sensor 292 is configured to monitor the level of the seeds in the planting chamber 258 and, if the seed level falls below the predefined level, the level sensor 292 is configured to notify the control system 208 whereby the control system 208 can direct additional seeds from the second seed storage unit 324 to the planting chamber 258 for planting. In particular, when such a notification is received from the level sensor 292 with regard to the seeds from the bulk supply, the control system 208 is configured to actuate the sluice plates 341, 342 of the second seed storage unit 324 to thereby release additional seeds from the container 336 to the delivery tube 372. In turn, the delivery tube 372 directs the seeds to the fourth port 384 of the diverter 373. Here, though, because the planting operation has already started, and because the subsequent seeds are needed to continue/complete the current planting operation, the control system 208 is configured to position the second gate 380 of the diverter 373 to block access (and a corresponding path) to the second port 382 along the flow route 386 (see, also,
In general, the second seed storage unit 424 of this embodiment is similar to the second seed storage units 224, 324 described above. For example, the storage unit 424 of this embodiment again generally includes a container 436 configured to hold the bulk supply of seeds therein, and the support 437 configured to releasably hold the container 436 on the planting unit 206. In particular, the support 437 includes a nest 438 configured to receive a dispensing spout 439 of the container 436 (when the container 436 is coupled thereto) and a moveable brace 440 configured to secure/retain the container 436 in the support 437. As such, the container 436 may be selectively removed from the support 437 (via pivoting movement of the brace 440 upward relative to the container 436) in order to receive the bulk supply of seeds therein, and then, once filled, re-coupled to the support 437. In so doing, the dispensing spout 439 of the container 436 is generally aligned with the nest 438, and the brace 440 is then positioned back over the container 436 to retain the container 436 in the support 437.
In this embodiment, the dispensing spout 439 of the container 436 includes a moveable slide 441 configured to selectively move between a closed position in which the slide 441 inhibits movement of seeds from out of the container 436 through the spout 439, and an open position in which the slide uncovers an opening of the container 436 and releases the seeds from the container 436. In addition in this embodiment, the support 437 includes an actuator 494 configured to transfer seeds released from the container 436 to the seed meter 220 of the planting unit 206 (broadly, means for portioning the seeds from the container 436).
As best shown in
Further, in this embodiment, the dispensing spout 439 of the container 436 is provided, generally, in the form of a lid or cover that is removable from the container 436 (e.g., via a threaded connection, via snap-fit connection, etc.) to allow for filling the container 436 with the bulk supply of seeds. In other example embodiments, though, the dispensing spout 439 may be formed integral with the container 436, and the container 436 may then include other openings, doors, etc. to facilitate filling the container 436 with the bulk supply of seeds.
With that said, the second seed storage unit 524 of this embodiment is provided generally in the form of a motorized seed feeder. In particular, the seed storage unit 524 generally includes a hopper 536 (broadly, a container) for holding the bulk seeds, and a feed wheel 594 (having teeth, paddles, etc.) (broadly, an actuator) in communication with the hopper 536 for portioning the seeds from the hopper 536 (via operation of motor 589). As such, in operation of the seed storage unit 524, the motor 589 is configured to rotate the feed wheel 594 (generally in a clockwise direction in
In connection therewith, the second seed storage unit 524 of this embodiment may be used to generally meter (and singulate) seeds from the second seed storage unit 524 (via the motor 589 and the feed wheel 594). As such, in various operations of the planter 200 (and the planting units 206 including the second seed storage unit 524) where seeds are directed from the second seed storage unit 524 to the planting tube 266 (and bypassing the seed meter 220), the second seed storage unit 524 may allow for dispensing the seeds therefrom generally one-by-one (instead of in spurts). As such, in this embodiment, singulation of the seeds from the second seed storage unit 524 may still be achieved for planting (directly via the planting tube 266), even when the seeds do not pass through the seed meter 220 (i.e., when they bypass the seed meter 220).
With that said, it should be appreciated that other means for portioning (e.g., measuring, metering, etc.) seeds from a second seed storage unit (e.g., from a bulk seed storage unit, etc.) may be used in the planter 200 within the scope of the present disclosure (e.g., other than volumetric chambers such as cavities 247, 447, etc.). As an example, one or more optical sensors may be positioned adjacent a container of the second seed storage unit and configured to count a number of seeds released from the container. In so doing, an actuator (e.g., a stepper motor, etc.) may be employed to open the container and allow seeds to flow past the one or more optical sensors and, when the sensors indicate that the desired number of seeds have been released, the actuator may be employed to close the container. As another example, a seed meter (e.g., such as one available from Gandy Company, etc.) may be positioned adjacent a container of the second seed storage unit and configured to count a number of seeds released from the container. In so doing, again, an actuator may be employed to open the container and allow seeds to flow into the seed meter and, when the seed meter indicates that the desired number of seeds have been released, the actuator may be employed to close the container. As can be appreciated, this use of the seed meter may help ensure that only the number of bulk seeds required for planting are actually released and/or delivered from the second seed storage unit (as opposed to always drawing the same number and/or volume of seeds from the second seed storage unit regardless of the planting requirements).
As such, the second seed storage unit may employ various different means for portioning seeds therefrom including, for example, means (e.g., cavities, etc.) for portioning fixed numbers and/or volumes of seeds (e.g., such that the same number and/or volume of seeds is portioned from the second seed storage unit each time, etc.), and means (e.g., seed meters, sensors, etc.) for portioning variable numbers/volumes of seeds (e.g., such that a same number and/or volume of seeds may be metered from the second seed storage unit each time or such that a different number and/or volume of seeds may be metered from the second seed storage unit, etc.), all within the scope of the present disclosure.

The input device 609 is coupled to (and is in communication with) the processor 603 and may include, for example, one or more of a keyboard, a pointing device, a mouse, a touch sensitive panel (e.g., a touch pad or a touch screen, etc.), another computing device, and/or an audio input device. Further, in various example embodiments, a touch screen, such as that included in a tablet, a smartphone, or similar device, may behave as both the presentation unit 607 and the input device 609.
Further, the illustrated computing device 601 also includes a network interface 611 coupled to (and in communication with) the processor 603 and the memory 605. The network interface 611 may include, without limitation, a wired network adapter, a wireless network adapter, a mobile network adapter, or other device capable of communicating to one or more different networks, including the network 212, the planters 100, 200, and/or the GPS receiver 110. In some example embodiments, the computing device 601 may include the processor 603 and one or more network interfaces incorporated into or with the processor 603.
In view of the above, in some implementations, the planters of the present disclosure may be used in (or in association with) breeding programs (e.g., to plant test plots, etc.) and, in connection therewith, may enable the freedom to make adjustments and fine tuning of breeding pipelines in ways that were previously unfeasible (based on the ease of switching between different ones of the seed storage units “on the fly” allowed by the diverters described herein).
In addition, the planters of the present disclosure may be used to plant fields without alleys or with different arrangements (or patterns) of alleys so that the planted environments may more closely represents those in which customers will use the seeds (i.e., how customers will actually plant their fields with the given seeds). The planters of the present disclosure may also be used to plant plots in fields with boundaries defined between and/or around the plots anywhere (based on the ease of switching between different ones of the seed storage units “on the fly,” as allowed by the diverters described herein). Thus, through use of the planters herein, boundaries between/around plots may be defined anywhere (i.e., rows of seeds can be planted with alleys, without alleys, with check plants (e.g., from seeds in bulk storage units, etc.), without check plants, and any iteration thereof, etc.). What's more, in some instances, “check plants” (e.g., based on seeds from the second seed storage units (or bulk storage units), etc.) may be planted in those spaces instead (i.e., in the spaces where alleys may traditionally be located). The habit of these check plants is sufficiently conspicuous that humans or algorithms can be taught to recognize, thereby serving as reliable markers of the boundaries between test plots. The planters described herein make switching to this planting scheme (e.g., planting fields without alleys, etc.) much easier and more efficient.
Previously, in planting test plots in fields, researchers have been limited to planting seeds to be tested (e.g., seeds from first seed storage units, etc.) in grid patterns, wherein alleys between the plots then all line up (e.g., where the alleys are formed when seeds are advanced in seed meters of the planters from staging chambers to planting chambers, etc.). This is shown in
As can thus be seen, the planters herein allow for near continuous planting of seeds from both the first and second seed storage units in a variety of different patterns, and with or without alleys. They also may also be used to plant fields with boundaries between and/or around plots defined anywhere (based on the ease of switching between different ones of the seed storage units “on the fly” allowed by the diverters described herein).
The planters of the present disclosure may also allow for postponing decisions about which particular types of seeds to plant at certain locations in the fields until the planters actually reach those points in the fields (again, based on the ease of switching between different ones of the seed storage units “on the fly” allowed by the diverters described herein). As can be appreciated, this provides flexibility in planting over the conventional prescription-based planting plans (where receptacles of first seed storage units are filled with seeds based on the given planting plans, and the plans are then locked in place). For example, an initial planting plan may indicate that seeds from one particular receptacle of the first seed storage unit are to be planted at a certain location in a field (e.g., in short plots of 10-30 plants of the same genotype, etc.). However, in one instance, when the planter reaches that location, information may be provided to the planter (via one or more sensors mounted to or remote from the planter and in communication with the planter (either directly or via a network connection), via artificial intelligence in communication with the planter, etc.) indicating that additional seeds (from one or more additional receptacles of the first seed storage unit having seeds with the same genotype (or seeds with different genotypes)) should also be planted in the field at the location (e.g., in longer plots of hundreds of plants, etc.). The additional seeds may then be directed to planting units of the planter as desired (e.g., to a particular chamber of the seed meter or directly to a planting tube via the diverter, etc.). In still another instance, when the planter reaches the location, information may be provided to the planter (via one or more sensors in communication with the planter, or otherwise) indicating that the location is unsuitable for the seeds from the first seed storage unit for some reason (e.g., a drone with a moisture sensor may indicate that the location was a flood zone and would not be suitable for test seeds, etc.). Here, the planter may then be configured to remap the planting plan and direct seeds from the second seed storage unit to the diverter and, for example, directly to the planting tube, to plant bulk seeds in the location (in order to fill the flood zone gap, for example, with check plants, etc.).
In addition, and as indicated above, the planters of the present disclosure may permit for better “alley control” during planting. In general, during conventional planting operation, when seeds are delivered to the staging chambers of seed meters, there are periods of time that the planters move forward but no seeds are planted (while the seeds are rotated from the staging chambers to the planting chambers and while seeds are wiped from the seed discs). This is typically where alleys are created, whereby such alleys then help inhibit carryover of seeds between plots. However, in some instances such alleys may not be desired. That said, in some implementations, the diverters herein enable the planters to combine the contents of different sets (or cells) of seeds from the first seed storage units directly into the planting chambers of the seed meters, thus avoiding having to rotate the seed meter, causing wiping effects, and creating undesired alleys between the two sets of seeds. What's more, in other implementations, the diverters herein enable the planters to direct seeds from the first and/or second seed storage units directly to planting tubes to allow for continuous planting at the alleys (and, again, avoiding having to rotate the seed meter and causing a wiping effect).
Further, the planters of the present disclosure may allow for mixed planting of seeds from the first seed storage units together with seeds from the second seed storage units into a single plot (i.e., mixed plots of seeds) (again, based on the ease of switching between different ones of the seed storage units “on the fly” allowed by the diverters described herein). In so doing, desired numbers and/or volumes of bulk seeds from the second seed storage units may be delivered to the seed meters and combined with seeds from the first seed storage units (e.g., in the planting chambers of the seed meters, etc.). The combined seeds may then be planted, to provide plots comprising certain percentages of bulk seeds mixed in with the seeds from the first seed storage units. These mixed plots may provide more flexible ways to produce “Refuge In a Bag” (RIB)-type planting results, which traditionally must be planned out before planting when the receptacles of the first seed storage units are being filled/prepared (whereby such RIB results may allow for a mixture of some disease (or insect) susceptible seeds/plants among otherwise tolerant seeds/plants to slow disease (or insect) evolution) (e.g., in desired percentages of each seed/plant to be planted such as five percent of one and ninety-five percent of another; ten percent of one and ninety percent of another; ten percent of one, ten percent of another, and then eighty percent of a third; fifty percent of one and fifty percent of another; etc.), or they may allow for planting a small number of “male” plants in a plot comprising mostly female plants, etc. This may also be accomplished by combining seeds from the same seed storage units, in which different seeds stored within the same seed storage units may be delivered to (and combined within) the seed meters. And, as above, the combined seeds may then be planted, to provide plots having desired percentages of each of the different seeds.
While the above description is provided in the context of planters, it should be appreciated that the present disclosure (e.g., the seed transport systems described herein, the diverters described herein, the storage units described herein, etc.) may also be applicable to directing seeds (or other small objects) from first locations to second locations in other systems. For example, the present disclosure may be applicable to seed processing lines where different types of seeds are distributed from different supplies of seeds to different containers (e.g., to cassettes, etc. in preparing for planting; etc.), prior to the containers then being transported to other machines for devices, such as planters or other seed processing devices 266 (see, e.g., Applicant's co-owned US Patent Application Publication No. US 2018/0317375 and International PCT Publication No. WO 2016/200825, the entire disclosures of which are incorporated herein by reference; etc.). In connection therewith, in some embodiments, it should be appreciated that the present disclosure may be applicable to and/or utilized in fixed and/or indoor environments, such as warehouses, laboratories, etc. whereby it is not limited to fields or planters.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the invention, and all such modifications are intended to be included within the scope of the invention.
Example embodiments have been provided so that this disclosure will be thorough, and will fully convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, assemblies, and methods, to provide a thorough understanding of embodiments of the present disclosure. It will be apparent to those skilled in the art that specific details need not be employed, that example embodiments may be embodied in many different forms and that neither should be construed to limit the scope of the disclosure. In some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail.
Specific dimensions, specific materials, and/or specific shapes disclosed herein are example in nature and do not limit the scope of the present disclosure. The disclosure herein of particular values and particular ranges of values for given parameters are not exclusive of other values and ranges of values that may be useful in one or more of the examples disclosed herein. Moreover, it is envisioned that any two particular values for a specific parameter stated herein may define the endpoints of a range of values that may be suitable for the given parameter (i.e., the disclosure of a first value and a second value for a given parameter can be interpreted as disclosing that any value between the first and second values could also be employed for the given parameter). For example, if Parameter X is exemplified herein to have value A and also exemplified to have value Z, it is envisioned that parameter X may have a range of values from about A to about Z. Similarly, it is envisioned that disclosure of two or more ranges of values for a parameter (whether such ranges are nested, overlapping or distinct) subsume all possible combination of ranges for the value that might be claimed using endpoints of the disclosed ranges. For example, if parameter X is exemplified herein to have values in the range of 1-10, or 2-9, or 3-8, it is also envisioned that Parameter X may have other ranges of values including 1-9, 1-8, 1-3, 1-2, 2-10, 2-8, 2-3, 3-10, and 3-9.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms “a”, “an” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
When an element or layer is referred to as being “on”, “engaged to”, “connected to” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to”, “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” and the phrase “at least one of” includes any and all combinations of one or more of the associated listed items.
Although the terms first, second, third, etc. may be used herein to describe various elements, components, seeds, members and/or sections, these elements, components, seeds, members and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, seed, member or section from another element, component, seed, member or section. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, seed, member or section discussed below could be termed a second element, component, seed, member or section without departing from the teachings of the example embodiments.
Spatially relative terms, such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
This application claims the benefit of, and priority to, U.S. Provisional Application No. 62/835,334, filed on Apr. 17, 2019. The entire disclosure of the above application is incorporated herein by reference.
