    FIELD
    [0001] The present invention relates to a system to distribute seeds and treatments relevant to the successful development or growth of seeds. BACKGROUND
    [0002] Sometimes it is desired to treat seeds or soil around the seeds with protector, growth promoter or other treatments relevant to the successful growth or development of the seeds. For this purpose, the seeds can be distributed in a first operation and the treatment can be applied in a separate second operation, or the seeds and treatment can be distributed in the same operation. Similarly, the treatment can be distributed continuously along a furrow in which the seeds have been deposited, or the treatment may be selectively distributed so as to closely match the seed locations in the furrow. Modern seeding systems distribute seed and treatment in the same operation in order to maximize efficiency, and selectively distribute treatment in order to minimize rejects.
    [0003] In such a system, a first tube delivers the seed and a second tube delivers the treatment into the furrow in front of the seed. However, any part of the treatment that remains in or on the second tube can run directly onto the seed and potentially damage the seed. In another system, a sensor can detect seed delivery, and an electronically controlled valve located at a lower end of the second tube and within the groove can open in response to the detected seed delivery to deliver treatment. However, the electronically controlled valve, including wires connected to it, can be damaged by dirt or stones in the groove and can be difficult to access for cleaning, repair or replacement.
    [0004] This background approach above is intended to provide information related to the present invention that is not necessarily prior art. Document US2013/269578 A1 discloses a system for automatically detecting and spraying plants and/or precursors as they are planted in the ground, including a seed tube to release seeds and a controller that can control valve operation to dispense fluid into a seed. SUMMARY
    [0005] The invention is defined by the appended claims, in particular independent claim 1. Modalities of the present invention solve the problems and limitations described above and others by locating the treatment delivery tube in front of the seed delivery tube (in with respect to the direction of travel) so that any runoff from the treatment is less likely to fall onto the seeds and by locating the treatment delivery tube between the double discs of a furrow opening wheel so that a lower portion of the tube The treatment delivery valve and an associated lower valve are protected by the discs and are therefore less likely to be damaged by dirt or stones in the groove. Additionally, an electronically controlled top valve is located above the groove during operation and a pressure activated bottom valve is located near or within the groove during operation, which minimizes the potential for damage to the top valve and increases accessibility for maintenance and repair it.
    [0006] In various deployments of this modality, the seeding system may additionally include any one or more of the following additional features. The treatment can take the form of a liquid, a solid, a powder, a granule or a crystal, and can be or include a type of fertilizer, an insecticide, an herbicide, a fungicide or a growth promoter. The first and second valves can be configured to release treatment over, adjacent to, or both behind and in front of (relative to the direction of travel) the one or more seeds. The seeding system may additionally include a nozzle connected to the second outlet of the second conduit and configured to spray the treatment in a substantially circular pattern around the one or more seeds. The seeding system can include a plurality of such seeding units. FIGURES

    [0018] The following detailed description of embodiments of the invention refers to the attached Figures. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those of ordinary skill in the art to practice the invention. Other modalities can be used and changes can be made without departing from the scope of the claims. The following description is therefore not limiting. The scope of the present invention is defined only by the appended claims.

Separate references to "an modality", "modality" or "modalities" in this description do not necessarily refer to the same modality and are not mutually exclusive unless otherwise indicated. Specifically, a resource, structure, action, etc. described in one embodiment may also be included in other embodiments, but are not necessarily included. Thus, particular implementations of the present invention may include a variety of combinations and/or integrations of the modalities described herein.
    [0020] Widely distinguished, the present invention provides a seeding system configured to both distribute seeds and distribute a treatment in a furrow in a single operation. In particular, a treatment delivery tube is located in front of a seed delivery tube (with respect to the direction of travel) so that any runoff from the treatment is less likely to fall onto the seed dispensed and the seed delivery tube. The treatment is located between the double discs of a furrow opening wheel so that a lower portion of the treatment delivery tube and an associated lower valve are protected by the discs and are therefore less likely to be damaged by dirt or stones. in the groove. Additionally, an electronically controlled upper valve is located substantially above the groove during operation and a pressure activated lower valve is located near or substantially within the groove during operation, which minimizes the potential for damage to the upper valve and increases accessibility for maintenance and repair it.
    [0021] Referring to Figure 1, a first embodiment of the seeding system 10 may include a seeding apparatus 12 and can be dragged behind a tractor 14 or other vehicle in a direction of travel over a field 16. The seeding apparatus 12 it may take the form of or include a crop row planter, seeder or similar apparatus configured to selectively distribute seed. Referring also to Figures 2 to 8, seeding apparatus 12 may include a plurality of separate seeding units 18, wherein each seeding unit 18 is configured to open a furrow 20 using a seed opening wheel. groove 22 including first and second angularly oriented disks 24a, 24b or other mechanism, distribute the seeds 26 and treatment in the groove 20 using a delivery system 28 and close the groove 20 with the use of a wheel. 30 groove closure or other mechanism. In various implantations, the treatment may take the form of a liquid, a solid, a powder, a granule or a crystal, and may be or include a type of a fertilizer, an insecticide, an herbicide, a fungicide, or a growth promoter. .
    [0022] The delivery system 28 may include a first seed delivery conduit 32 coupled to a first container 34 containing the seeds 26; a second treatment delivery conduit 36 coupled to a second container 38 containing the treatment 40; a first electronically controlled valve 42; a second mechanically activated valve 44; and a controller 46.
    [0023] The first seed distribution conduit 32 may be a tube, channel or other directional guide configured to guide the seeds 26 from the first container 34 to the furrow 20. The first conduit 32 may include a first outlet 48 and the system The delivery system 28 may be configured to periodically deliver one or more of the seeds 26 via the first outlet 48. To that end, the delivery system 28 includes a metering mechanism 50 configured to control the movement of the seeds 26 from the first container 34 to first conduit 32. Measuring mechanism 50 is electronically actuated.
    The second treatment delivery conduit 36 may be a tube, channel or other directional guide configured to guide the treatment 40 from the second container 38 to the groove 20. The second conduit 36 may include an upper end 52, an end lower 54 and a second outlet 56 at the lower end 54. The dispensing system 28 may be configured to periodically dispense the treatment 40 via the second outlet 56. In an implant, the second outlet 56 may be located in front of the first outlet 48 with respect to the direction of travel (which is indicated by a large right-facing arrow in Figure 3) and between the first and second angularly oriented disks 24a, 24b of the furrow opening wheel 22. Locate the second outlet 56 between the first and second discs 24a, 24b reduces the risk of damage from dirt and stones and reduces the risk of contaminating the first outlet 48 with overspray at high rates or p repressions.
    [0025] The first electronically controlled valve 42 is located at the upper end 52 of the second conduit 36 so as to be positioned substantially outside the groove 20 during operation and can be configured to control the movement of treatment 40 from the second container 38 towards to the second valve 44. Locating the first valve 42 outside the groove 20 removes size limitations and other design limitations, and reduces the risk of damage to the first valve 42 and facilitates cleaning and service.
    [0026] The second mechanically activated valve 44 may be located at the lower end 54 of the second conduit 36 so as to be positioned substantially within the groove 20 during operation and may be configured to control the release of treatment 40 from the second outlet 56 and to groove 20. In an implant, the second valve 44 may be a pressure activated or "hold" valve configured to open and close in response to a pressure exerted by treatment 40 in second conduit 36. Then, in operation, the first valve 42 may allow a treatment volume 40 to move from second container 38 towards second valve 44 in response to an electrical control signal from controller 46, and second valve 44 may release the treatment volume 40 in the second conduit 36 to the groove 20 in response to the pressure exerted by the treatment volume 40 in the second conduit 36. Locate the second valve 44 just above the second outlet 56 facilitates the control of treatment inertia 40 and reduces the risk of cavitation that may, in some way, occur. Since the second valve 44 is mechanically operated (e.g., through changes in pressure), no electrical wires extend along the second conduit 36 to control the second valve 44.
    [0027] In various deployments, the first and second valves 42, 44 may be configured to release treatment 40 over, adjacent to, either in front or behind (relative to the direction of travel) or in a pattern around the one or more seeds 26. The delivery system 22 may additionally include a nozzle 58 connected to the second outlet 56 of the second conduit 36 and configured to spray the treatment 40 in a pattern around the one or more seeds 26.
    [0028] Controller 46 is configured to control the operation of the first electronically controlled valve 42 with respect to the delivery of treatment 40 and the measurement mechanism 50 with respect to the delivery of seeds 26. In various implementations, the controller 46 may include hardware and/or software electronic, can communicate control signals wirelessly or via a cable, and can take the form of a single control unit for the seeding system 10 configured to control the plurality of seeding units 18, in the form of a seeding unit. separate control for each of a plurality of groups of seeding units 18 or the form of a separate control unit for each of seeding units 18.
    [0029] In a deployment, the seeding units 18 can, in general, perform their distributions at substantially the same time. However, under certain circumstances the seeding units 18 may make their distributions at different times. For example, when the seeding apparatus 12 rotates, the inner seeding units may move slower than the outer seeding units, thus, the inner seeding units may distribute less frequently than the outer seeding units. In either case, controller 46 can control the timing of dispenses.
    [0030] Referring to Figure 9, in operation an exemplary implementation of the seeding unit 18 can function substantially as follows. As the sowing unit 18 moves forward in the direction of travel, the furrow opening wheel 22 can create the furrow 20 in which the seeds 26 and treatment 40 can be distributed, as shown in step 100. A first electronically controlled valve 42 may open to allow a treatment volume 40 to move from second container 38 to second treatment delivery conduit 36, as shown in step 102. Treatment volume 40 in second conduit 36 may exerting pressure on the second pressure activated valve 44, thereby causing the second valve 44 to open and deliver the treatment 40 in the groove 20, as shown in step 104. A seed 26 can then be released from the first container 34 to move through the first seed delivery conduit 32 and be dispensed into groove 20 as shown in step 106. Steps 102 and 104 may be repeated to dispense a second volume of d. the treatment 40 in the furrow 20 in front of the seed 26 as shown in step 108. The furrow closing wheel 30 can then close the furrow 20 over the seed 26 and the treatment 40 as shown in step 110. The process integer can then be repeated as many times as necessary as seeding unit 18 moves along field 16.
    [0031] Therefore, the present invention provides several advantages over the prior art. In particular, the treatment delivery tube 36 is located in front of the seed delivery tube 32 (with respect to the direction of travel) so that any runoff from the treatment 40 is less likely to fall onto the delivered seeds 26 and is located. between the first and second angularly oriented double discs 24a, 24b of the groove opening wheel 22 so that the lower portion 54 of the treatment delivery tube 36 and the lower valve 44 associated therewith are protected by the discs 24a, 24b and they are therefore less likely to be damaged by dirt or stones in the groove 20. Additionally, the first upper valve 42 is located substantially above the groove 20 during operation and the second lower valve 44 is located close to or substantially within the groove 20 during operation. operation, which minimizes the potential for damage to the first valve 42 and increases accessibility for maintenance and repair.
