The present disclosure relates generally to combining different types of seeds, and more particularly to preparing seed mixes having target quantities of different types of seed and target ratios of the different types of seeds.
This section provides background information related to the present disclosure which is not necessarily prior art.
Seeds are often sold in sacks which contents are typically determined by the number of seeds in the sack. For example, sacks may include around 80,000 total seeds. Often, two different types of seeds are included in the sacks. This may include harvesting the two different types of seeds into separate containers, and then unloading the seeds from the containers into batches of mixed seeds in a desired volumetric ratio. The batches of mixed seeds can then be used to prepare the sacks of seeds. However, the desired volumetric ratio of seeds in the batch does not necessarily carry through to the individual sacks of seeds prepared from the batch.
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 processes for preparing seed mixes having target quantities and target ratios of different types of seeds. In one example embodiment, a process generally includes portioning a quantity of a first type of seed from a bulk supply of the first type of seed, portioning a quantity of a second type of seed from a bulk supply of the second type of seed, and combining the portioned quantities of the first and second types of seeds to prepare the seed mix. The combined quantities of the first and second types of seeds in the seed mix are substantially equal to the target quantity, and a ratio of the quantity of the first type of seed to the quantity of the second type of seed is substantially equal to the target ratio.
Example embodiments of the present disclosure generally relate to systems for preparing seed mixes having target quantities and target ratios of different types of seeds. In one example embodiment, a system generally includes a first dispensing assembly configured to portion a quantity of a first type of seed from a bulk supply of the first type of seed, a second dispensing assembly configured to portion a quantity of a second type of seed from a bulk supply of the second type of seed, and a mixing assembly configured to receive the portioned quantities of the first and second types of seeds as a seed mix. The combined quantities of the first and second types of seeds in the seed mix are substantially equal to the target quantity, and a ratio of the quantity of the first type of seed to the quantity of the second type of seed is substantially equal to the target ratio.
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.
Example embodiments will now be described more fully with reference to the accompanying drawings.
Example embodiments are 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, devices, 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.
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, and/or components, 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” 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, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer 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, region, layer or section discussed below could be termed a second element, component, region, layer 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.
With reference now to the drawings,
The different types of seeds used in preparing the seed mix may include any desired types of seeds within the scope of the present disclosure. For example, the seeds may include corn seed, cotton seed, canola seed, soybean seed, or rice seed, etc. Also for example, the seeds may include transgenic seeds having one or more transgenes; seeds having two or more different transgenes; seeds having two or more different transgenes each conferring a pest resistance to the same pest but by different modes of action; seeds having two or more different transgenes each conferring a pest resistance to different pests; seeds having stacks of different configured to provide stacked transgenic events; seeds having two or more stacks of different transgenes; seeds having transgenes encoding proteins with insecticidal properties, pesticidal properties, etc.; seeds having transgenes conferring pest resistance to one or more of Ostrinia nubilalis, Diatraea graandiosella, Diabrotica barben, Diabrotica virgifera virgifera, Richia albicosta, Agrotis ipsilion, Spodoptera frugiperda, Helicoverpa zea, etc.; seeds treated with pesticidal agents, fungicidal agents, herbicidal agents, fertilizer agents, biocontrol agents, etc.; non-transgenic seeds; combinations of such seeds; etc.
For example, in the illustrated embodiment a first type of seed (e.g., a major component of the seed mix, etc.) may include transgenic seeds. The transgenic seeds may have one or more properties or expressions such as herbicidal tolerance, dicamba resistance, corn rootworm resistance (including resistance to various species of rootworm), cornborer resistance (including resistance to various species of cornborer), corn earworm resistance, cotton bollworm resistance, pink bollworm resistance, fall armyworm resistance, other pest resistance, etc. And, a second type of seed (e.g., a minor component of the seed mix, etc.) may include refuge seeds.
The refuge seeds may be transgenic or they may be non-transgenic. The refuge seeds may include seeds having different properties or expressions than the transgenic seeds, or less than all of the properties or expressions of the transgenic seeds (e.g., less than all of the pesticide properties or expressions, etc.). The refuge seeds may still include, however, properties or expressions such as insecticidal tolerance, herbicidal tolerance, fungicidal tolerance, etc. within the scope of the present disclosure. For example, the refuge seeds may include seeds of one or more plant varieties that can be grown into plants that act as a refuge for pests that would typically feed on plates grown from the transgenic seeds, but for genetic modification of the transgenic seeds to resist such pests. In addition, the refuge seeds may be uniform in nature, in that they are comprised of seeds from a single variety of plant, or they may be non-uniform in nature and comprise seeds from two or more varieties of plant. Further, the refuge seeds may be provided that are particularly attractive to a given crop pest, at least relative to other plants grown from the seed mix (e.g., from the transgenic seeds, etc.). For example, the refuge seeds may be selected based on expected color, timing of silks or flowering, plant health, vigour, etc. to be nutritionally attractive to certain pests, and/or they may comprise one or more transgene that results in the production of pest attractants.
As shown in
The predetermined quantities of the first and second types of seeds to be added to the seed mix are selected based on a target quantity of total seeds to be included in the seed mix and a target ratio of the first type of seed to the second type of seed to be achieved in the seed mix. Thus, when prepared, the seed mix will have a total quantity of seeds substantially equal to the target quantity of total seeds, and a ratio of the first type of seed to the second type of seed substantially equal to the target ratio.
The target quantity of first and second types of seeds to be included in the seed mix may include any discrete quantity of seeds, between about a hundred seeds and about a hundred million seeds, or any other desired quantity within the scope of the present disclosure. The target quantity of seeds may include a quantity of seeds suitable for reception within a particular type of packaging, size of packaging, etc. Further, the target quantity of seeds may be based on use for the seed mix, demand for the seed mix, crop size, field size, equipment compatibility, equipment capacity, transport requirements, other factors considered in determining seed capacities, etc. For example, the target quantity of seeds may be about 80,000 seeds, as generally associated with a commercial bag of seed; about 4 million seeds, as generally associated with a commercial SeedPak™ container; or any other desired quantity of seeds.
The target ratio of the first type of seed to the second type of seed to be achieved in the seed mix may include any desired ratio within the scope of the present disclosure. For example, the seed mix may include about nineteen parts of the first type of seed and about one part of the second type of seed. As such, a ratio of the first type of seed to the second type of seed in the seed mix is about 19:1 (i.e., the seed mix comprises about 95% of the first type of seed and about 5% of the second type of seed). As such, about 95% of the resulting crop will be yielded from the first type of seed and about 5% of the resulting crop will be yielded from the second type of seed. Alternatively, seed mixes may have ratios of first types of seeds to second types of seeds of about 1:1, about 2:1, about 3:1, about 4:1, about 9:1, about 10:1, about 20:1, about 49:1, about 50:1, about 99:1, ratios therebetween, etc. within the scope of the present disclosure. Further, seed mixes may have ratios of the first types of seeds to the second types of seeds based on acceptable ranges of ratios (e.g., within a given tolerance, etc.), such as a range of about 22:1 to about 15:1, etc. within the scope of the present disclosure.
The target ratio of the first and second types of seeds in the seed mix may be selected to provide crops (planted from packages containing the seed mix) having certain desired percentages of plants grown from the first and second types of seeds. For example, the target ratio may be selected based on a desired seed mix strategy, based on a desired IRM program, etc. A seed mix package of such first and second types of seeds may include a percentage of refuge seeds and a percentage of transgenic seeds, thus eliminating issues of enforcement and compliance with regulatory standards for recombinant crops and block refuge requirements.
The first and/or second types of seeds used in preparing the seed mix according to the example process 2 may include seeds having substantially uniform sizes (e.g., AF, AF2, AR, AR2, P22, ARPM, etc.), shapes, and/or colors within industry recognized tolerances. As such, the bulk supplies of the first and/or second types of seeds used to prepare the seed mix in the example process 2 may include seeds each having substantially the same size, shape, and/or color. While not required, providing a seed mix in which the first and second types of seeds each have the same size, shape, and/or color may help ensure that the particular seed mix is planted, and may help inhibit subsequent removal of, for example, the second type of seed (e.g., the refuge seed type, etc.) from the seed mix by end users (e.g., in an attempt by the end users to only use the first type of seed (i.e., the transgenic seed type), etc.).
The bulk supplies of the first and second types of seeds may be provided in any acceptable number of different quantities known in the art, for example, for providing multiple seeds to automated seed blending systems, etc. In some example embodiments, bulk supplies of seeds may include packages of seeds (e.g., bags of seeds, SeedPak™ containers, etc.), outputs of seeds from other processing systems, bulk stores of seeds in bins or containers, etc.
In the example process 2, portioning a predetermined quantity of the first and second types of seeds includes portioning a desired (or target) weight of the first and second types of seeds from their bulk supplies into a receiving container. The desired weight of the seeds may include, for example, a predetermined weight based on the particular size of the seed (e.g., AF2, etc.), a predetermined weight based on the particular type of seed, etc. And, the desired weight may be associated with, or indicative of, a particular number/quantity of the first and second types of seeds (e.g., based on an average density of the first and second types of seeds in their respective bulk supplies, etc.) to be included in the seed mix. In other example embodiments, processes for preparing seed mixes may include portioning desired volumes of different types of seeds to receiving containers (where the desired volumes are associated with, or indicative of, a particular number of seeds). In still other example embodiments, processes for preparing seed mixes may include counting desired quantities of different types of seeds and then delivering the counted quantities to receiving containers to prepare the seed mixes.
Table 1 illustrates example correlations/conversions between seed weight and seed quantity for various different size combinations of first and second types of seeds for use in achieving a seed mix having a target quantity of seeds of about 80,000 and a target ratio of the first type of seed to the second type of seed of about 19:1. Such correlations/conversions can be prepared as necessary for desired seeds and used in the example process 2. For a seed mix requiring the first and second seed types to each have seed sizes of AR, a weight of about 46.8 pounds of the first type of seed would be portioned from the bulk supply of the first type of seed and delivered to the receiving container and a weight of about 2.2 pounds of the second type of seed would portioned from the bulk supply of the second type of seed and delivered to the receiving container to thereby prepare the seed mix.
With continued reference to
The example process 2 further includes deploying the packaged seed mix as desired (as indicated generally at reference number 12). This can include, for example, transporting the seed mix (in the packages) to end users (e.g., farmers, etc.) for planting in fields. The packages can provide for efficient and/or effective transport of the seed mix to the end users and/or for planting of the seed mix in the fields (e.g., for distribution to planting equipment, etc.).
While not shown in
In other example embodiments, processes for preparing seed mixes may include combining portioned quantities of first, second, and third types of seeds. Target quantities of seeds in these seed mixes are inclusive of the portioned quantities of the first, second, and third types of seeds. Here, the third type of seed may include at least one property or expression not included in the first or second types of seeds. In one of the example embodiments, the target quantity of the first, second, and third types of seeds in the seed mix is about 80,000 total seeds. And, a target ratio of the first type of seed to the second type of seed to the third type of seed in the seed mix is about 8:1:1, such that the seed mix includes about 80% of the first type of seed, about 10% of the second type of seed, and about 10% of the third type of seed.
In still other example embodiments, processes for preparing seed mixes may include combining portioned quantities of first, second, and third types of seeds where the second types of seeds in the seed mixes include refuge seed types to be included in the seed mixes at predetermined percentages (e.g., about 1% to about 25%, about 5% to about 10%, etc.) such that the same quantities of the second types of seeds are included in the seed mixes regardless of the quantities, percentages, etc. of the first and third types of seeds, etc. The remainder of the total quantities of seeds in the seed mixes is then made up of the first and second types of seeds, combined at various percentages and/or ratios. In one of the example embodiments, the second type of seed is to be included in the seed mix at a predetermined percentage of about 5%. And, the first and third types of seeds are to be included in the seed mix at equal percentages of about 47.5%. Here, a target ratio of the first type of seed to the second type of seed to the third type of seed is about 9.5:1:9.5. In another one of the example embodiments, the second type of seed is to be included in the seed mix at a predetermined percentage of about 5%. And, the first and third types of seeds are to be included in the seed mix at respective percentages of about 20% and abut 75%. Here, a target ratio of the first type of seed to the second type of seed to the third type of seed is about 4:1:15.
In still other example embodiments, processes for preparing seed mixes may include combining portioned quantities of more than three different types of seeds.
The illustrated system 120 generally includes a first dispensing assembly 122 and a second dispensing assembly 124. The first dispensing assembly 122 is configured to portion (e.g., weigh, count, measure volumes, etc.) a predetermined quantity of seeds from a bulk supply 126 of a first type of seed. And, the second dispensing assembly 124 is configured to portion (e.g., weigh, count, measure volumes, etc.) a predetermined quantity of seeds from a bulk supply 128 of a second type of seed. Any suitable dispensing assembly may be used for portioning quantities of the first and second types of seeds (and subsequently delivering the seeds from the dispensing assembly as desired) within the scope of the present disclosure.
The illustrated system 120 also includes a seed mixing assembly 130 configured to receive and blend, mix, etc. the first and second types of seeds to form the seed mix. Blending the first and second types of seeds together may be achieved passively (e.g., through gravity, etc.) as the seeds are received in the seed mixing assembly 130. For example, the seeds may generally blend uniformly together as they are received together in the seed mixing assembly 130. Blending the first and second types of seeds may also include active blending, mixing, etc. operations to help generally uniformly distribute the seeds in the seed mix. Any suitable seed mixing assembly may be used within the scope of the present disclosure.
The illustrated system 120 further includes a packaging assembly 132 configured to receive the seed mix from the seed mixing assembly 130 into a package. This operation may further help uniformly blend the first and second types of seeds together. Thus, when the seed mix is received in the package, the first and second seeds are generally uniformly mixed. And, a total quantity of the first and second types of seeds in the package is generally equal to the target quantity, and a ratio of the first type of seed to the second type of seed in the package is generally equal to the target ratio. Moreover, each package produced by the system 120 includes substantially the target quantity of total seeds and the target ratio of the first type of seed to the second type of seed. Any suitable packaging assembly may be used within the scope of the present disclosure.
Operation of the illustrated system 120 may be controlled by a controller assembly 134 (e.g., a remote controller assembly, a hardwired controller assembly, etc.). The controller assembly 134 may include one or more personal computers, laptops, workstations, servers, PDAs, other processing devices, etc. known in the art for providing control signals to various components of the automated system 120 (e.g., the first dispensing assembly 122, the second dispensing assembly 124, the seed mixing assembly 130, the packaging assembly 132, etc.). The controller assembly 134 may be programmed by a user at the outset of a production run to direct the system 120 in the packaging of seed mixes. For example, the controller assembly 134 may receive various inputs from the user such as sizes of seeds being handled, target ratios between first and second types of seeds, target quantities of seeds to be included in packages, known weight correlations between seed sizes and seed quantities, quantities of first and/or second types of seeds to be portioned, etc. The controller assembly 134 may then utilize the inputs received from the user to provide control signals to the various assemblies of the system 120 to prepare desired seed mixes (e.g., seed mixes having target quantities of different types of seeds and/or desired ratios of the different types of seeds, etc.). In other example embodiments, various different types of information may be supplied to controller assemblies to ensure that dispensing assemblies portion appropriate quantities of seeds to provide target quantities of seeds having ratios equal to predetermined values.
As shown in
The first type of seed is provided to the first dispensing assembly 222 from a bulk supply (not shown) of the first type of seed. A first transport 236 is configured to convey the first type of seed from the bulk supply to the first dispensing assembly 222. In the illustrated embodiment, the first transport 236 includes a pipe 238, and the first type of seed is gravity conveyed through the pipe 238, as desired, to the first dispensing assembly 222. In other example embodiments, systems may include, for example, conveyors, buckets, other types of transports, etc. for transporting seeds from bulk supplies of first types of seeds to first dispensing assemblies.
The first dispensing assembly 222 includes a housing 240 supporting therein a surge bin (not shown), generally known in the art, for initially receiving and holding a temporary amount of the first type of seed from the first transport 236. The first dispensing assembly 222 operates to deliver desired quantities of the first type of seed from the temporary amount held in the surge bin to the seed mixing assembly 230. And, the first transport 236 operates to refill the surge bin with the first type of seed as necessary (to maintain the temporary amount of the first type of seed held therein). As such, a supply of the first type of seed is generally always readily available in the surge bin for delivery to the seed mixing assembly 230.
In an example operation of the first dispensing assembly 222 (which is generally known in the art), a first gate (not shown) operates to selectively release (via gravity) the first type of seed from the surge bin to a vibratory feeder (not shown) located within the housing 240 generally below the surge bin. A second gate (not shown) then operates to selectively release (via gravity) the first type of seed from the vibratory feeder to first and second hoppers (not shown) located within the housing and generally below the vibratory feeder. As an example, the vibratory feeder may initially operate to fill the first hopper with seeds. Then, as the first hopper delivers a desired quantity of the seeds to the seed mixing assembly 230, the vibratory feeder may operate to fill the second hopper with seeds. And then, as the second hopper delivers a desired quantity of the seeds to the seed mixing assembly 230, the vibratory feeder may again operate to fill the first hopper with seeds. This sequential use of the first and second hoppers (which may span, for example, about 4-6 seconds, etc.) can reduce wait time for preparing the seed mixes. And, this operation may continue as desired, for example, until a desired number of seed mixes are prepared, etc. In other example embodiments, systems may include first dispensing assemblies having a number of hoppers other than two (e.g., three, etc.).
The hoppers of the first dispensing assembly 222 are each configured to receive and hold a suitable amount of the first type of seed necessary, for example, to prepare individual ones of the desired seed mixes. In the illustrated embodiment, for example, the first and second hoppers are each configured to hold at least about 76,000 seeds, i.e., at least about 95 percent of the 80,000 total seeds to be included in each of the seed mixes (so that a ratio of the first type of seed to the second type of seed in each of the prepared seed mixes is about 19:1). In other example embodiments, systems may include first dispensing assemblies having hoppers configured to hold more than or less than about 76,000 seeds, for example, depending on target quantities of seeds to be included in seed mixes prepared by the systems, or depending on target ratios of various types of seeds to be included in seed mixes prepared by the systems, etc.
With continued reference to
The second dispensing assembly 224 includes a surge bin 252, generally known in the art, for initially receiving and holding a temporary amount (e.g., about twenty-two cubic feet, etc.) of the second type of seed from the second transport 244. The second dispensing assembly 224 operates to deliver desired quantities of the second type of seed from the temporary amount held in the surge bin 252 to the seed mixing assembly 230. And, the second transport 244 operates to refill the surge bin 252 with the second type of seed as necessary (to maintain the temporary amount of the second type of seed held in the surge bin 252). As such, a supply of the second type of seed is generally always readily available in the surge bin 252 for delivery to the seed mixing assembly 230.
In an example operation of the second dispensing assembly 224, a first gate (not shown) operates to selectively release (via gravity) the second type of seed from the surge bin 252 to a vibratory feeder 254 located generally below the surge bin 252. A second gate (not shown) then operates to selectively release (via gravity) the second type of seed from the vibratory feeder 254 to a weighing plate 256. The weighing plate 256 is associated with a load cell (not shown) for monitoring and/or measuring weight of the second type of seed received on the weighing plate 256. The weighing plate 256 collects the second type of seed released from the vibratory feeder 254 and, once a desired weight of the second type of seed is achieved (i.e., a preprogrammed weight associated with about 4,000 seeds of the second type of seed in the illustrated embodiment (e.g., within acceptable tolerances, etc.)), directs the second type of seed (e.g., via gravity and selective operation of a gate, etc.) to first and second hoppers 258a and 258b located adjacent the weighing plate 256. As an example, the weighing plate 256 may initially operate to fill the first hopper 258a with weighed seeds, and then immediately receive and weigh additional seeds from the vibratory feeder 254. As the first hopper 258a delivers the seeds to the seed mixing assembly 230, the weighing plate 256 may operate to fill the second hopper 258b with weighed seeds. The weighing plate 256 may then again immediately receive and weigh additional seeds from the vibratory feeder 254. And then, as the second hopper 258b delivers the seeds to the seed mixing assembly 230, the weighing plate 256 may again operate to fill the first hopper 258a with weighed seeds. This sequential use of the first and second hoppers 258a and 258b can reduce wait time for preparing the seed mixes. And, this operation may continue as desired, for example, until a desired number of seed mixes are prepared, etc. In other example embodiments, systems may include second dispensing assemblies having a number of hoppers other than two (e.g., three, etc.). In other example embodiments, individual scales may be associated with each of the first and second hoppers 258a and 258b for weighing seeds received from surge bin 252 and delivering the weighed seeds to the respective hoppers 258a and 258b (e.g., instead of or in addition to the weighing plate 256, etc.).
The hoppers 258a and 258b of the second dispensing assembly 224 are each configured to receive and hold a suitable amount of the second type of seed necessary, for example, to prepare individual ones of the desired seed mixes. In the illustrated embodiment, for example, the first and second hoppers 258a and 258b are each configured to hold at least about 4,000 seeds, i.e., at least about 5 percent of the 80,000 total seeds to be included in each of the seed mixes (so that a ratio of the first type of seed to the second type of seed in each of the prepared seed mixes is about 19:1). In other example embodiments, systems may include second dispensing assemblies having hoppers configured to hold more than or less than about 4,000 seeds, for example, depending on target quantities of seeds to be included in seed mixes prepared by the systems, or depending on target ratios of various types of seeds to be included in seed mixes prepared by the systems, etc.
The second dispensing assembly 224 also includes a return 260 coupled to lower portions of the first and second hoppers 258a and 258b. The return 260 is included in the system 220, for example, as part of quality control of seeds being added to the seed mixes. For example, the return 260 can operate to empty un-wanted quantities of seed from the first and second hoppers 258a and 258b based on analysis (e.g., visual analysis, etc.) of the seeds along the second transport 244, at the second dispensing assembly 224, etc. The return 260 can also operate to empty misfed quantities of seeds received in the first and second hoppers 258a and 258b from the second transport 244, etc. The illustrated return 260 includes pipes 262 extending from each of the first and second hoppers 258a and 258b to a bin 264. The pipes 262 transport, as desired (e.g., via operation of a gate, a valve, etc.), the quantities of seed to be emptied from the hoppers 258a and 258b to the bin 264 for subsequent recycling into the system 220 (e.g., for return to the bulk supply 228 of the second type of seed, etc.), for storage, for disposal, etc. In other example embodiments, systems may include first dispensing assemblies having returns as part of quality control of first types of seeds being added to seed mixes prepared by the systems.
With additional reference now to
In an example operation of the illustrated seed mixing assembly 230, the second dispensing assembly 224 delivers a portioned quantity of the second type of seed (i.e., a desired weight of the second type of seed, as weighed by the weighing plate 256, having a known weight associated with a quantity of about 4,000 seeds) from its first hopper 258a, via a chute 272, to the first weigh bucket 270a. A guide 274 is provided to help direct the seeds from the chute 272 into the first weigh bucket 270a. The first dispensing assembly 222 delivers the first type of seed from its first hopper (via a main chute 276 and a secondary chute 277 for fine-tuned delivery) into the first weigh bucket 270a (either after the second dispensing assembly 224 begins delivering seeds, at about the same time the second dispensing assembly 224 begins delivering seeds, or before the second dispensing assembly 224 begins delivering seeds). As the first type of seed is added to the first weigh bucket 270a, it generally mixes, blends, etc. with the second type of seed in the weigh bucket 270a. At the same time, a load cell associated with the first weigh bucket 270a incrementally monitors and/or measures the additional weight of the first type of seed being added. When a desired weight of the first type of seed (i.e., a weigh associated with about 76,000 seeds (e.g., within acceptable tolerances, etc.)) is added to the first weigh bucket 270a (taking into account the known weight of the second type of seed already in the weigh bucket 270a), delivery of the first type of seed is stopped. The first weigh bucket 270a then operates to release (via gravity through a lower door 278) the combined first and second types of seeds (i.e., as a seed mix) to the packaging assembly 232 for further processing (which operation may also allow for blending of the seeds as they move from the first weigh bucket 270a to the packaging assembly 232). Operation of the seed mixing assembly 230 to fill the second weigh bucket 270b with portioned quantities of the first and second types of seeds and to then deliver the combined seeds to the packaging assembly 232 is substantially the same.
In the illustrated embodiment, the first and second weigh buckets 270a and 270b are operated generally in series (in connection with the hoppers (e.g., hoppers 258a and 258b, etc.) of the first and second dispensing assemblies 222 and 224), such that only one of the weigh buckets 270a and 270b releases seeds to the packaging assembly 232 at any one time. While the first weigh bucket 270a is releasing seeds to the packaging assembly 232 (as just described), the second weigh bucket 270b is being filled with the first and second types of seeds from the first and second dispensing assemblies 222 and 224. This provides a generally sequential, series, uniform, etc. operation of the first and second weigh buckets 270a and 270b in receiving first and second types of seeds from the first and second dispensing assemblies 222 and 224, as well as in releasing the combined seeds to the packaging assembly 232.
In other example embodiments, systems may include seed mixing assemblies configured to substantially simultaneously receive first and second types of seeds into weigh buckets at about the same time. Here, determining weights of the first type of seed to be substantially simultaneously added to the weigh buckets with the second type of seeds is accomplished by taking into account known weights of the second type of seeds being added (as measured by weigh plates of second dispensing assemblies of the systems). In still other example embodiments, systems may include seed mixing assemblies configured to receive pre-weighed quantities of both first and second types of seeds into buckets from first and second dispensing assemblies (such that a weight of the first type of seed is known and a weight of the second type of seed is known). The buckets may then also be weighed as part of a quality control procedure to confirm that the total weight is achieved. In still other example embodiments, systems may include seed mixing assemblies having a number of weigh buckets other than two (e.g., three, etc.).
The illustrated system 320 generally includes first and second dispensing assemblies 322 and 324 and a packaging assembly 332 located generally below the first and second dispensing assemblies 322 and 324. The first dispensing assembly 322 is configured to deliver, in repeated operations, a portioned quantity of the first type of seed to SeedPak™ containers (e.g., the SeedPak™ container 382 in
The first type of seed is provided to the first dispensing assembly 322 from a bulk supply (not shown) of the first type of seed. A first transport 336 is configured to convey the first type of seed from the bulk supply to the first dispensing assembly 322. In the illustrated embodiment, the first transport 336 includes a pipe 338, and the first type of seed is conveyed through the pipe 338, as desired, to the first dispensing assembly 322 (e.g., gravity, pneumatically, mechanically, etc.).
The first dispensing assembly 322 includes a housing 340 supporting therein a surge bin (not shown), generally known in the art, for initially receiving and holding a temporary amount of the first type of seed from the first transport 336. The first dispensing assembly 322 operates to deliver the first type of seed from the temporary amount held in the surge bin to the packaging assembly 332. And, the first transport 336 operates to refill the surge bin with the first type of seed as necessary (to maintain the temporary amount of the first type of seed held therein). As such, a supply of the first type of seed is generally always readily available in the surge bin for delivery to the packaging assembly 332.
In an example operation of the first dispensing assembly 322 (which is generally known in the art), a first gate (not shown) operates to selectively release (via gravity) the first type of seed from the surge bin to a vibratory feeder (not shown) located within the housing 340 generally below the surge bin. A second gate (not shown) then operates to selectively release (via gravity) the second type of seed from the vibratory feeder to a weighing plate (not shown). The weighing plate is associated with a load cell for monitoring and/or measuring weight of the first type of seed received on the weighing plate. The weighing plate collects the first type of seed released from the vibratory feeder and, once a desired weight of the first type of seed is achieved (i.e., a weight associated with about 3,800,000 seeds of the first type of seed in the illustrated embodiment), directs the first type of seed (e.g., via gravity and selective operation of a gate, etc.) to the packaging assembly 332 generally immediately below the first dispensing assembly 322.
The surge bin of the first dispensing assembly 322 is configured to receive and hold a suitable amount of the first type of seed necessary, for example, to prepare the desired seed mixes within the SeedPak™ containers. In the illustrated embodiment, for example, the surge bin is configured to hold at least about 3,800,000 seeds, i.e., at least about 95 percent of the 4,000,000 total seeds to be included in each of the seed mixes (so that a ratio of the first type of seed to the second type of seed in each of the prepared seed mixes is about 19:1). In other example embodiments, systems may include first dispensing assemblies having surge bins configured to hold more than or less than about 3,800,000 seeds, for example, depending on target quantities of seeds to be included in seed mixes prepared by the systems, or depending on target ratios of various types of seeds to be included in seed mixes prepared by the systems, etc.
The second type of seed is provided to the second dispensing assembly 324 of the system 320 from a bulk supply 328 of the second type of seed. In the illustrated embodiment, the bulk supply 328 of the second type of seed is included in containers 342. The containers 342 allow for easy refilling, replacing, etc. of the second type of seed during operation to maintain the supply of the second type of seed as desired. The containers 342 may also allow for easy changing of the second type of seed, for example, from one type of refuge seed to another type of refuge seed, etc.
The second dispensing assembly 324 generally includes transports 344a and 344b (having conveyors 366), a first surge bin 352, a weighing unit 356, and a second surge bin 384. The second dispensing assembly 324 operates to portion quantities of the second type of seed from the temporary amount held in the first surge bin 352 and then deliver the portioned quantities of seeds to the second surge bin 384 for subsequent addition to the SeedPak™ containers (at the packaging assembly 332). As part of this operation, the transport 344a operates to refill the first surge bin 352 with the second type of seed as necessary to maintain the temporary amount of the second type of seed held in the first surge bin 352 so that a supply of the second type of seed is generally always readily available in the first surge bin 352 for delivery to the weighing unit 356. And, the transport 344b operates to convey weighed quantities of seeds from the weighing unit 356 to the second surge bin 384 for subsequent delivery to the packaging assembly 332.
In an example operation of the second dispensing assembly 324, a first gate (not shown) operates to selectively release (via gravity) the second type of seed from the first surge bin 352 to the weighing unit 356 generally below the first surge bin 352. The weighing unit 356 is associated with a load cell (not shown) for monitoring and/or measuring weight of the second type of seed received in the weighing unit 356. The weighing unit 356 collects the second type of seed released from the first surge bin 352 and, once a desired weight of the second type of seed is achieved (i.e., a weight associated with about 200,000 seeds of the second type of seed in the illustrated embodiment), directs the second type of seed (e.g., via gravity and selective operation of a gate, etc.) to the transport 344b. The transport 344b delivers the weighed quantities of the second type of seed to the second surge bin 384 which is configured to then subsequently deliver (via a pipe 386) the quantities of the second type of seed to a SeedPak™ container (e.g., SeedPak™ container 382 in
The second dispensing assembly 324 also includes a return 360 coupled to a lower portion of the second surge bin 384. The return 360 is included in the system 320, for example, as part of quality control of seeds being added to the seed mixes. For example, the return 360 can operate to empty un-wanted quantities of seed from the second surge bin 384 based on analysis (e.g., visual analysis, etc.) of the seeds along the second transports 344a and/or 344b, at the surge bins 352 and 384, etc. The return 360 can also operate to empty misfed quantities of seeds received in the first surge bin 352 (and weighing unit 356), etc. The return 360 operates to transport, as desired (e.g., via operation of a gate, a valve, etc.), the quantities of seeds to be emptied from the second surge bin 384 to bin 364 for subsequent recycling into the system 320 (e.g., return to the bulk supply 328 of the second type of seed, etc.), for storage, for disposal, etc.
The packaging assembly 332 of the illustrated system 320 includes a floor structure 388 for sequentially moving (e.g., via rollers, etc.) SeedPak™ containers into the packaging assembly 332 for receiving portioned quantities of the first and second types of seeds from the respective first and second dispensing assemblies 322 and 324. Thus, SeedPak™ containers can be sequentially positioned generally under the first and second dispensing assemblies 322 and 324 to receive portioned quantities of the first and second types of seeds. And, each of the prepared SeedPak™ containers will contain a seed mix having desired quantities (e.g., target quantities, etc.) of the first and second types of seeds and desired ratios (e.g., target ratios, etc.) thereof. In addition, the SeedPak™ containers each receive seeds from the first and second dispensing assemblies 322 and 324 at about the same time. As such, the first and second types of seeds are generally uniformly blended, mixed, etc. together as they are delivered to the SeedPak™ containers.
As shown in
More particularly, the first dispensing assembly 422 is operable to provide a quantity of the first type of seeds to a weighing mechanism (not shown), which is associated with the receiving container of the first dispensing assembly, to thereby portion a quantity of the first type of seed from the bulk supply 426. For example, the first dispensing assembly 422 may operate to fill the receiving container with seeds until the weighing mechanism indicates that a desired weight is achieved (indicative of a particular number of the first type of seeds). The weighing mechanism may then operate to confirm that an accurate quantity of the first type of seed has been portioned.
The illustrated system 420 also includes a second dispensing assembly 424 disposed adjacent the bulk supply 428 of the second type of seed. The second dispensing assembly 424 is configured to portion a quantity of the second type of seed from the bulk supply 428 of the second type of seed for use in preparing the seed mix. As with the bulk supply 426 of the first type of seed, the bulk supply 428 of the second type of seed includes seeds having substantially the same size (within industry recognized tolerances). In addition (although not required), the second type of seeds may have substantially the same size as the first type of seeds.

With further reference to
The illustrated delivery sub-assembly 494 generally includes four different sets of tubes 495, suitable, for example, for staging four separate portioned quantities of the second type of seed received from the second dispensing assembly that are to be combined with the first type of seed received from the first dispensing assembly 422 (
The illustrated delivery sub-assembly 494 also includes a return path 460, which may be employed to empty un-wanted quantities of seed from the conveyor assembly 444 (e.g., based on analysis (e.g., visual analysis, etc.) of the seeds taking place along a path of the conveyor assembly 444 and/or at the delivery sub-assembly 494, etc.), misfed quantities of seed from the conveyor assembly, etc. The return path 460 may empty the quantity of seed into a bin 464 for recycling into the system 420, for storage, for disposal, etc.
The packaging assembly 432 includes two chutes 496 and 497 each configured to receive and hold a portioned quantity of the first type of seed (received from the first dispensing assembly 422) together with a portioned quantity of the second type of seed (received from the second dispensing assembly 424 (via the delivery sub-assembly 494). Each chute 496 and 497 is thereby configured to receive portioned quantities of both the first and second types of seeds together within the chute 496 and 497. In addition, the portioned quantities of the first and second types of seeds can be delivered to each of the chutes (e.g., either chute 496 or chute 497, etc.) at about the same time such that the first and second types of seed may be generally mixed, blended, etc. together within the given chute (e.g., within chute 496 or chute 497, etc.) (e.g., such that the first and second types of seeds are blended in the total quantity, etc.). And, the combined portioned quantities of the first and second types of seeds received within the given chute (e.g., within chute 496 or within chute 497, etc.) ultimately provides a total quantity of first and second types of seeds that is substantially equal to a target quantity of seeds, and that has a ratio of the first type of seed to the second type of seed that is substantially equal to a predetermined value.
The chutes 496 and 497 each include a pair of doors 498 selectively operable between a closed position to allow the chutes 496 and 497 to be filled with the combined quantities of the first and second types of seeds, and an open position to allow the chutes to release the seeds. The doors 498 are initially closed to allow the chutes 496 and 497 to fill with the combined quantities of the first and second types of seeds. The doors 498 may then be opened to allow the combined first and second types of seeds to be released from the chutes 496 and 497 into respective packages (not shown). In the illustrated embodiment, the seeds fall from the chutes 496 and 497 via gravity, further mixing, blending, etc. the first and second types of seeds. In other example embodiments, packaging assemblies may include one or more chutes structured without doors to directly pass seeds through the chutes (and thus so as not to retain combined seeds in the chutes) from dispensing assemblies into packages.
In the illustrated embodiment, the chutes 496 and 497 are operated generally in series, such that only one of the chutes 496 or 497 releases combined seeds into a package at any one time. While one of the chutes 496 or 497 is releasing combined seeds into a package, the other chute 496 or 497 is being filled with seeds from the first and second dispensing assemblies 422 and 424. This ultimately provides a generally sequential, series, etc. operation of the chutes 496 and 497.
In other example embodiments, weighing devices (e.g., scales, etc.) may be associated with the chutes 496 and/or 497 to further weight quantities of the first and/or second types of seeds as they are transferred to the chutes 496 and/or 497.
The dispensing assembly 522 of this embodiment is configured to receive seeds in the seed trays 505 disposed around the drums 501. The seeds are held in place in the seed trays 505 via a vacuum. The detectors 503 are then operable to image the seed trays 505 (or a portion thereof) and count the number of seeds present in the imaged seed trays 505, and then determine if an acceptable number of seeds are present in the imaged seed trays 505. If an acceptable number of seeds are present, the vacuum is released and the seeds are removed by seed removal device 507 via passage 509 for collection in a container (not shown). As the seeds are released, a count may be incremented so as to provide a precise total count of the quantity of seeds ejected into the container.
The dispensing assembly 522 may be managed and/or controlled by a control sub-assembly 511.
Example methods (e.g., process 2, etc.) systems (e.g., system 120, 220, 320, 420, etc.) of the present disclosure generally provide for mixing, blending, etc. of the first and second types of seeds, for example, when the seeds are transferred into weigh buckets of seed mixing assemblies, as well as when the seeds are dispensed from the weigh buckets to packaging assemblies, etc. As such, the methods and systems may be viewed as providing blended seed mixes for packaging in which the seeds are generally uniformly mixed throughout the packages. In this manner, segregation of the first and second types of seeds within the packages may be minimized, and a semi-uniform or uniform dispersal of the first and second types of seed may be achieved within the packages. Moreover, once the total quantity of combined first and second types of seeds is within a package, the package is sealed and transported (e.g., via conveyor assemblies, transport machinery, etc.) for storage, delivery, planting, etc. In this manner, the methods and systems combine (e.g., mix, blend, etc.) the portioned quantities of the first and second types of seeds as desired directly and immediately before the seeds are sealed within the packages without further processing. In other example embodiments, systems may include active blending devices to help further ensure generally uniform dispersal of different types of seeds within packages.
Example methods (e.g., process 2, etc.) and systems (e.g., system 120, 220, 320, 420, etc.) of the present disclosure may be used to package single types of seeds within the scope of the present disclosure. For example, the example methods and systems may be used to package first types of seeds without second types of seeds (e.g., the methods and systems may be operated so that only the first types of seeds are delivered to the packages, with the second types of seeds bypassing the packages, etc.).
Seed mixes prepared in accordance with the present disclosure provide repeatable, accurate seed mixes each having about a target quantity of seeds and each having about a target ratio of seeds. For example, the total quantity of seeds in each final package prepared by the example processes and systems may be counted (e.g., via weight correlations such that the total quantity of seeds in each package is weighed, etc.). As such, the total quantity of seeds in each package and the ratio of different types of seeds in each package is generally consistent from package to package such that methods and systems of the present disclosure can provide reproducible, accurate outputs for each seed mix (and for each package including a seed mix).
In addition, seed mixes prepared in accordance with the present disclosure can have two or more different types of seeds including, for example, transgenic seeds and refuge seeds. As such, the seed mixes can be used in seed mix refuge strategies as part of insecticide resistance management (IRM) programs. Seed mix refuge strategies describe operations for deploying into a field of crops some percentage of refuge seeds which sprout and develop into mature refuge plants that allow certain pests to surface (and to which plants grown from the transgenic seeds are resistant). Thus, the seed mixes can be packaged to provide a refuge in a bag to farmers that, when planted, provide tools for delaying or possibly eliminating onset of resistance development to properties and/or expressions not shared between types of seeds included in the seed mixes. The RIB is one way of ensuring that all transgenic insect protected crop fields have associated refuge lacking insect protection. By blending insect protected seed with unprotected seed, refuge will be present in all fields independent of the product selected by a particular farmer.
Further, seed mixes prepared in accordance with the present disclosure may provide yield protection and/or may lead to increased yields relative to planting the same proportion of unprotected seed as a separate block (i.e., in a traditional structured refuge). This can occur because unprotected plants in a field planted with an unstructured refuge will tend to be surrounded by insect-protected plants. This will decrease the average amount of damage occurring to unprotected plants because there will not be larvae moving over from other adjacent unprotected plants, as there would be in a block refuge and pest populations will tend to be smaller. Smaller pest populations on unprotected plants can mean less damage and higher yields.
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.
