    [0001] [001] The invention relates, in general, to agricultural systems and, more particularly, to a retractable assembly set for an agricultural soil analyzer. BACKGROUND OF THE INVENTION
    [0002] [002] Certain agricultural operators can conduct soil analysis before starting planting operations in agricultural fields. Soil analysis can assist in planning planting operations to increase planting yield or efficiency. For example, an analysis that indicates a high clay content can influence the application of fertilizer or seeding operations in specific areas. Ultimately, operators can reduce waste and save time by limiting planting to undesirable areas of agricultural fields. In addition, unwanted soil compaction can be reduced by making fewer passes in the agricultural field. However, typical soil analysis can be time-consuming, expensive and data-intensive.
    [0003] [003] US 2005-172733 A1 describes a set of soil sampling supported by an implement structure to move through the field. The sampling set includes a tapered cylindrical shoe and a soil collection chute. The cutting shoe comprises a main cutting edge mounted to move across the ground in a horizontal direction and cut a sample of cylindrical core. A sine device is provided to measure at least one property of the soil. The sampling set is moved between a lowered position where the cutting shoe is positioned at a selected sampling depth, and an elevated position where the cutting shoe is positioned above the soil surface and the soil sample contained in the chute is conducted in contact with the sensor device.
    [0004] [004] EP 1 241 488 A2 describes an apparatus for analyzing and mapping the soil for physical and / or chemical properties of the soil. The apparatus comprises a sensor to measure the conductivity of the soil through electromagnetic induction and is mobile over an area of the soil to be analyzed. The information obtained is subsequently used to generate soil maps of the area, showing variations in the range of parameters, such as nutrients, pH, water volume and soil type, so that better soil management strategies can be developed. DESCRIPTION OF THE INVENTION
    [0005] [005] According to the invention, a retractable mounting assembly includes a frame assembly. The frame assembly includes at least one substantially rigid frame member. The structure assembly is configured to facilitate the movement of an agricultural soil analyzer from a first position close longitudinally to a rear end of an agricultural implement to a second position longitudinally to the rear of the first position, in relation to a direction of travel of the agricultural implement, the structure set is configured to position the agricultural soil analyzer above and close to a surface of an agricultural field while in the second position, and each of at least one substantially rigid structure member is formed from a non-interactive material electrically.
    [0006] [006] The at least one structure member includes a base configured to couple the agricultural implement, a first support arm and a second support arm. The first support arm comprises a first end rotatably coupled to the base and a second end, where the first support arm is configured to rotate with respect to a first axis with respect to the base. The second support arm comprises a first end rotatably coupled to the second end of the first support arm, and a second end is configured to couple with the agricultural soil analyzer, where the second support arm is configured to rotate with respect to a second axis relative to the first support arm.
    [0007] [007] In some embodiments, the first support arm is configured to rotate around a first geometry axis between a stored position configured to position the agricultural soil analyzer near longitudinally to a rear end of the implement, and an operating position configured to position the agricultural soil analyzer above and near a surface of an agricultural field and longitudinally to the rear of the rear end of the implement relative to a direction of travel of the implement. In some embodiments, the first support arm is formed from an electrically non-interactive and substantially rigid material.
    [0008] [008] In another embodiment, an agricultural soil analysis system includes a non-contact electrical conductivity probe. The non-contact electrical conductivity probe is configured to measure the electrical conductivity of the soil in an agricultural field. The system also includes an assembly set. In some embodiments, the mounting kit includes a frame assembly attached to the non-contact electrical conductivity probe and is configured to attach to a rear end of an agricultural implement. The frame assembly includes at least one substantially rigid frame member, and each of the at least one substantially rigid frame member is formed from a non-electrically interactive material. The system includes an interface module connected communicatively to the agricultural soil analyzer and configured to connect communicatively to an agricultural implement control system.

DESCRIPTION OF ACCOMPLISHMENTS OF THE INVENTION
    [0010] [010] One or more specific embodiments of the present invention will be described below. In an effort to provide a concise description of these achievements, all features of an actual deployment may not be described in the specification. It should be noted that, in the development of any real deployment like this, as in any engineering or model project, numerous specific deployment decisions need to be made to achieve the specific goals of the developers, such as compliance with system-related restrictions and related to the business, which may vary from one deployment to another.

    [0011] [011] When introducing the elements of various embodiments of the present invention, the articles "one", "one", "o", "a", "said" and "said" are intended to mean that there are one or more of the elements . The terms "who understands", "who includes" and "who has" are intended to be inclusive and mean that there may be additional elements in addition to the elements listed. Any examples of operating parameters and / or environmental conditions are not exclusive to other parameters / conditions of the disclosed achievements.
    [0012] [012] The achievements described in this document refer to a system for assembling and using an agricultural soil analyzer to monitor an agricultural field. In particular, a system for mounting the analyzer on a soil conditioning implement and obtaining data is revealed. According to the invention, the assembly assembly includes a structure assembly that has a first support arm coupled to a second support arm. The second support arm is configured to rotate around a second geometry axis. In some embodiments, the assembly set includes actuators configured to drive the first support arm to rotate around a first geometry axis and drive the second support arm to rotate around the second geometry axis. For example, while the mounting assembly is in a stored position, the actuator can be retracted so that the frame assembly is substantially perpendicular to the agricultural field. That is, the agricultural soil analyzer attached to the second support arm is located longitudinally close to a rear end of the agricultural implement. However, the actuator is configured to drive the assembly assembly to an operating position in which the structure assembly is substantially parallel to the agricultural field. Similarly, a second actuator is configured to drive the second support arm to the operating position in which the second support arm is substantially parallel to the agricultural field. In other words, the structure set positions the agricultural soil analyzer longitudinally to the rear of the stored position, described above, in relation to a direction of displacement of the agricultural implement. In addition, the agricultural soil analyzer is positioned above the surface of the agricultural field. In certain embodiments, the second actuator may include a cable or ribbon that extends between the implement and the second support arm. In addition, the second support arm is retractable and configured to extend away from the agricultural implement, thereby separating the analyzer from ferrous and / electrically interactive components of the agricultural implement. In certain embodiments, a support wheel supports the weight of the frame and analyzer assembly when the assembly assembly is in the operating position. In other embodiments, a frame can support the weight of the frame and analyzer assembly when the assembly assembly is in the operating position. In certain embodiments, the analyzer is coupled to the support arm. The second support arm is configured to hold the analyzer close to the agricultural field while in the operating position to allow the analyzer to obtain measurements from the agricultural field. For example, the analyzer can transmit and receive electromagnetic energy to and / or from the agricultural field. The data obtained by the analyzer can be directed to a wireless transmitter for storage on a remote server. The data can be used to generate three-dimensional soil maps for no-till operations.
    [0013] [013] Soil analyzes are conducted by non-contact and / or soil surface sensors that are used to obtain various soil properties while reducing disturbance in the agricultural field. Typically, using non-contact sensors, operators conduct soil analysis separately from planting, fertilization and / or preparation operations. For example, a walkway can be used to conduct soil analysis, in which the operator tows equipment over the agricultural field to obtain data for assessment. The data can then be evaluated to generate soil maps or produce maps that indicate a variety of properties of the field. Soil maps can be used for future tillage, fertilization and / or tillage operations. Then, subsequent steps can be used to condition the soil, fertilize the soil and / or deposit seeds in the soil. During the fertilization and / or planting process, the operator can consult the soil maps to adjust fertilizer rates and / or planting rates based on the properties obtained from the soil analysis. The use of multiple passages increases the cost and time spent by operators to condition, fertilize and plant the field. The combination of soil conditioning and analysis processes eliminates at least one field pass that operators can make when preparing fields for planting. In addition, by conducting soil analysis closer to actual planting operations, operators have better data related to current soil conditions, such as salinity, cation exchange capacity, clay content or the like. As a result, efficiency can be increased, along with performance.
    [0014] [014] Turning now to the Figures, and first with reference to Figure 1, a perspective view of an implementation of an agricultural implement 10 is illustrated in the form of a soil conditioner. However, in alternative embodiments, the implement 10 may be a field cultivator, a fertilizer applicator, a planter or the like. The implement 10 is configured to be towed behind a work vehicle, such as a tractor, in a travel direction 11. The implement 10 includes wheels 12 which are used to guide the implement 10 along an agricultural field 14. The implement 10 is fixed to the tractor by means of a coupling assembly 16. In certain embodiments, the coupling assembly 16 is connected by means of screws or other couplings suitable to an implement structure 18. The structure of the implement 18 includes a bar front tool 20 coupled to a plurality of blades 22, in the illustrated embodiment. Blades 22 are configured to make contact with agricultural field 14 to fragment the soil and prepare agricultural field 14 for planting. The structural members of the implement 10, such as the frame 18 and the coupling assembly 16, can be made of any suitable material, such as structural steel. In addition, the implement structure 18 includes a rear tool bar 24. The rear tool bar 24 is coupled to leveling bars 26, in the illustrated embodiment. Leveling bars 26 are configured to smooth the surface of agricultural field 14 in preparation for planting. In addition, implement 10 includes rotating baskets 28. Rotating baskets 28 are configured to condition the soil in preparation for planting.
    [0015] [015] In the illustrated embodiment, the implement 10 includes a rear hitch 30 coupled to the frame 18. In addition, a mounting set 32 (e.g., soil sampling mounting set) is attached to the rear hitch 30. The set mounting bracket 32 can be attached to the rear hitch 30 using any suitable connector (for example, pins, screws, etc.). Mounting set 32 is configured to support an agricultural soil analyzer 34 (e.g., probe, meter, detector, analyzer, etc.). In the illustrated embodiment, analyzer 34 is an electrical conductivity probe configured to operate by means of electromagnetic induction to determine the conductivity, susceptibility, thickness and / or the like of the agricultural field 14. Using an electrical conductivity probe as the analyzer 34 , soil disturbance can be reduced at the same time as relatively quick analyzes are obtained. In some embodiments, the analyzer 34 includes multiple receivers and transmitters to obtain information about the agricultural field 14. As will be discussed below, the information obtained by the analyzer 34 can be used to generate two- or three-dimensional soil maps of the agricultural field to improve operations planting. However, as mentioned above, other analyzers 34 can be used in other embodiments. Analyzer 34 is a non-contact analyzer (eg soil surface sensor; low interference or compaction sensor, etc.) that is configured to be positioned close to and above agricultural field 14 during data collection. As used in this document, close refers to a distance that allows the analyzer 34 to obtain accurate readings without significantly interfering or compacting the surface of the agricultural field 34. For example, in some embodiments, the analyzer 34 can be up to 15 centimeters (6 inches), 30 centimeters (12 inches), 60 centimeters (24 inches) or 90 centimeters (36 inches), among other distances, from the surface of agricultural field 14. In addition, as discussed in detail below, analyzer 34 can be integrated with other components or electronic systems that include a global positioning system (GPS), engine controls, data acquisition software and the like.
    [0016] [016] As will be described in detail below, the assembly set 32 is configured to extend and retract between a first position and a second position. In the illustrated embodiment, the analyzer 34 is close longitudinally to the rear end of the implement 10 while in the first position. However, while in the second position the analyzer 34 is positioned longitudinally to the rear of the first position, in relation to the direction of travel 11 of the implement 10. In addition, the analyzer 34 is positioned close to the surface of the agricultural field 14. In addition, the mounting set 32 and / or the components of mounting set 32 are formed with non-electrically interactive material, in the illustrated embodiment. As a result, analyzer 34 is separated from the ferrous and / or metallic components of the agricultural implement 10.
    [0017] [017] Figure 2 is a perspective view of mounting set 32 in a stored position 36. As will be described in detail below, mounting set 32 is foldable or retractable and configured to position analyzer 34 close to the field surface. agricultural 14. The assembly set 32 includes a structure set 33. In addition, the structure set 33 includes substantially rigid structure members 35, as described in detail below. In stored position 36, analyzer 34 is deactivated. That is, the data acquisition does not begin until the analyzer 34 is close to the surface of the agricultural field 14. In addition, a first support arm 38 (for example, the frame member 35) of the assembly set 32 is substantially perpendicular to the agricultural field 14 while the assembly set 32 is in the stored position 36. As shown, the first support arm 38 is pivotally coupled to the rear hitch 30 on a base 40. The base 40 is configured to secure the mounting set 32 to the rear hitch 30 or any other suitable location on the rear end of the implement 10. On illustrated embodiment, the first support arm 38 is coupled to the base 40 at a first end 42 of the first support arm 38. As mentioned above, the mounting set 32 is in the stored position 36 in Figure 2. As a result, the first arm support 38 is in a substantially vertical orientation in relation to the ground. However, the first support arm 38 is configured to rotate around a first geometry axis 44. As discussed in detail below, the rotation of the first support arm 38 around the first geometry axis 44 changes the mounting assembly 32 between the stored position 36 and an operating position, in which the analyzer 34 is positioned at the rear of the implement 10 and close to the ground surface.
    [0018] [018] As mentioned above, the first support arm 38 rotates around the first geometry axis 44 to change the set 32 between the stored position 36 and an operating position. In the illustrated embodiment, an actuator 46 drives the first support arm 38 to rotate around the first geometry axis 44. As shown, actuator 46 is a hydraulic cylinder configured to extend and retract a piston coupled to the first support arm 38 to drive the rotation around the first geometry axis 44. For example, when the piston is retracted the first support arm 38 is driven towards the stored position of the assembly 32 and when the piston is extended the first support arm 38 is driven towards to the operating position of the set 32. However, it must be assessed that alternative linear actuators (eg helical transmissions, electromechanical actuators, etc.) can be employed in alternative designs. In additional embodiments, a rotary actuator (for example, hydraulic, electric, etc.) can be used. In certain embodiments, a gear and pulley system can be used to drive the rotation of the first support arm 38. In addition, as will be discussed in detail below, a control system can be included to control the operation of the actuator 46.
    [0019] [019] Mounting set 32 also includes a pivot member 48 pivotally coupled to the first support arm 38 at a second end 50. In the illustrated embodiment, pivot member 48 is configured to pivot about a second geometric axis 52 In addition, the rotating member 48 is coupled to a second support arm 54 at a first end 56 of the second support arm 54. The second support arm 54 is configured to rotate about the second geometry axis 52 with respect to the rotation of the first support arm 38. That is, the second support arm 54 rotates about the second geometry axis 52 with the rotation member 48. The second support arm 54 is configured to support analyzer 34 at a second end 58 of the second support arm 54. As a result, the analyzer 34 is moved towards the position at the rear of the implement and close to the surface of the ground according to the first support arm. ions 38 and the second support arm 54 are moved to the operating position.
    [0020] [020] In the illustrated embodiment, an actuator 60 drives the second support arm 54 to rotate around the second geometry axis 52. As shown, actuator 60 includes cables 61 that extend from the base 40 to the rotation member 48 The cables 61 drive the rotation member 48 to rotate around the second geometry axis 52 as the first support arm 38 rotates around the first geometry axis 44. That is, the tension in the cables 61 increases as the first support arm 38 rotates around the first geometry axis 44, and this tension is applied to the rotation member 48 to drive the rotation member 48 to rotate around the second geometric axis 52. As a result, the second support arm 54 also rotates around of the second geometrical axis 52. The cables 61 are formed from non-interactive material electrically in the illustrated embodiment, as described in detail below. However, in alternative embodiments, the cables 61 can be straps, ropes, or any material capable of applying force to the rotating member 48 and / or the second support arm 54.
    [0021] [021] In the illustrated embodiment, a support wheel 62 is pivotally coupled to the second support arm 54. The support wheel 62 is positioned on the second support arm 54 so that the support wheel 62 is in a retracted position 64 while the mounting set 32 is in the stored position 36 and in a lowered position while the mounting set 32 is in the operating position. Consequently, the position of the support wheel 62 corresponds to the position of the second support arm 54. As discussed below, the support wheel 62 is configured to distribute the weight of the second support arm 54 and analyzer 34 as the mounting set 32 is in the operating position. In addition, the support wheel 62 is dimensioned to place the analyzer 34 close to the surface of the agricultural field 14 while the mounting set 32 is in the operating position. As a result, the support wheel 62 allows the analyzer 34 to monitor the soil without making contact with the surface of the agricultural field 14. In addition, the support wheel 62 distributes the weight of the second support arm 54 and the actuator 46, the which allows longer lengths of the first support arm 38 and the second support arm 54. It is assessed that although a support wheel 62 is shown in the illustrated embodiment, the second support arm 54 and / or the first support arm 38 can include several support wheels 62 in alternative designs. In addition, in the illustrated embodiment, the support wheel 62 is formed from a non-electrically interactive material.
    [0022] [022] The assembly set 32 and / or the associated components are constructed from non-electrically interactive materials, in the illustrated embodiment. As used herein, non-electrically interactive material refers to materials that do not substantially interfere with or influence surrounding electrical fields. For example, the assembly set 32 can be assembled from components formed of a thermoplastic, fiber-reinforced polymer or composite material. In addition, non-electrically interactive can refer to materials that are non-conductive electrically or substantially non-conductive electrically. As will be discussed in detail below, building assembly 32 from an electrically non-interactive material can improve the performance of analyzer 34. That is, a non-electrically interactive material substantially reduces interference from assembly 32, thereby thereby improving the accuracy of the agricultural soil analyzer 34. However, in certain embodiments, only part of the assembly set 32 is constructed from non-electrically interactive materials. For example, base 40 can be formed from a metallic material.
    [0023] [023] Figure 3 is a perspective view of the assembly set 32 in an intermediate position between the stored position 36 and the operating position. In the illustrated embodiment, the first support arm 38 rotates about the first geometric axis 44, via actuator 46, in a first direction 66, thereby moving the second end 50 of the first support arm 38 in a longitudinal direction 68 which is opposite the direction of travel 11 of the implement 10. As the first support arm 38 rotates around the first geometry axis 44, the second end 50 of the first support arm 38 is moved closer to the surface of the agricultural field 14. In addition, in the illustrated embodiment, the second support arm 54 is driven to rotate around the second geometry axis 52 in a second direction 70 by the actuator 60 (for example, the cables 61). As shown, the second direction 70 is opposite to the first direction. Consequently, the rotation in the second direction 70 drives the second end 58 of the second support arm 54 to move in the direction 68. As a result, the mounting set 32 is elongated as the mounting set 32 changes to the operating position therefrom. mode by moving the agricultural soil analyzer 34 to the rear.
    [0024] [024] As mentioned above, the second support arm 54 includes the support wheel 62 configured to switch between the retracted position 64 while the mounting set 32 is in the stored position 36, and a lowered position 72 while the mounting set 32 is in the operating position. In the illustrated embodiment, the support wheel 62 is rotated around a wheel axis 74 as the second support arm 54 rotates around the second axis 52 in the second direction 70. The support wheel 62 is mounted on the second arm support 54 so that gravity pulls the support wheel to the lowered position 72 as the mounting set 32 changes to the operating position. In addition, the support wheel 62 rotates back to the retracted position 64 as the mounting set 32 changes towards the stored position 36.
    [0025] [025] Figure 4 is a perspective view of the mounting set 32 in an operating position 76. As described above, the first support arm 38 is driven around the first geometry axis 44 in the first direction 66 by the actuator 46. In operating position 76, the first support arm 38 is substantially parallel to the surface of the agricultural field 14. In addition, the second support arm 54 is driven around the second geometry axis 52 in the second direction 70 by the actuator 60. As a result , the second support arm 54 is oriented substantially parallel to the surface of the agricultural field 14. In addition, the support wheel 62 makes contact with the surface of the agricultural field 14 to support the weight of the assembly set 32 in the operating position 76.
    [0026] [026] As shown, in the illustrated embodiment, the analyzer 34 is close to the surface of the agricultural field 14 while the assembly set 32 is in the operating position 76. As a result, the analyzer 34 is positioned to emit and / or receive electromagnetic energy to / from the soil without making contact with the surface of the agricultural field 14. Furthermore, in the illustrated embodiment, the mounting set 32 extends in the direction 68. As shown, the mounting set 32 extends from the rear end of the implement 10 in a rear direction in relation to the travel direction 11 of the implement 10. The extension of the assembly set 32 is configured to longitudinally separate the analyzer 34 from the ferrous and / or electrically interactive components of the agricultural implement 10, thus , allowing analyzer 34 to obtain readings with improved accuracy due to reduced interference from the electrically interactive components. In the illustrated embodiment, analyzer 34 is positioned approximately 2.4 meters (8 feet) to the rear of implement 10 in relation to the direction of travel 11. However, in other embodiments, analyzer 34 may be further or closer . For example, mounting set 32 can position analyzer 34 to be between 1.5 meters (5 feet) and 6 meters (20 feet) from the implement 10. Additionally, additional support wheels 62 can be attached to the the first support arm 38 and / or the second support arm 54 to support the mounting set 32 in embodiments that have sets that extend greater distances from the implement 10. In addition, multiple mounting sets 32 and analyzers 34 can be attached to the implement 10. For example, the mounting sets 32 can be mounted across the rear end of the implement 10 so that the analyzers 34 extend across the length of the implement 10. Furthermore, although the illustrated embodiment shows an analyzer 34 coupled to the mounting set 32, it is understood that multiple analyzers 34 can be coupled to the mounting set 32 at various locations along the first arm the support 38 and the second support arm 54. In addition, although the analyzer 34 in the illustrated embodiment is positioned substantially perpendicular to the second support arm 54, in other embodiments the analyzer 34 can be substantially parallel to the second support arm 54, or positioned at an angle (for example, twenty degrees, thirty degrees, forty-five degrees, etc.) in relation to the second support arm 54. It will be assessed that the orientation of the analyzer 34 can be adjusted according to the type of analyzer used (eg electrical, acoustic, chemical, etc.).
    [0027] [027] In other embodiments, the assembly set 32 may include a ramp to move the analyzer 34 to the rear and close to the surface of the agricultural field 14. For example, the analyzer can be coupled to an analyzer member that descends to the bottom of the ramp, which is coupled to the rear hitch 30. A wheel or frame can hold the analyzer member against the surface of the agricultural field 14 while the analyzer 34 is positioned close to the surface of the agricultural field 14. The analyzer member can be attached to the ramp by means of a cable and a pulley system can return the analyzer 34 and the analyzer member to the ramp for storage and transportation. In addition, in another embodiment, analyzer 34 can be coupled to the end of a linear actuator (for example, hydraulic cylinder). The linear actuator may include a wheel or blade configured to make contact with the surface of the agricultural field 14 when the actuator is extended. The actuator extension can move the analyzer 34 away from the implement 10 to the operating position. In a further embodiment, the assembly set 32 may include a single arm configured to rotate around the first geometry axis 44. An actuator can change the single arm between the stored position and the operating position.
    [0028] [028] Figure 5 is a perspective view of an assembly assembly 32 in stored position 36. As described above, assembly assembly 32 is foldable or retractable and configured to position analyzer 34 close to the surface of the agricultural field. 14. Mounting set 32 includes a frame set 33 comprising frame members 35. In addition, the first support arm 38 of mounting set 32 is substantially perpendicular to agricultural field 14 while mounting set 32 is at stored position 36. As shown, the first support arm 38 is pivotally coupled to the rear hitch 30 on the base 40. The base 40 is configured to secure the mounting set 32 to the rear hitch 30 or any other suitable location on the rear end of the implement 10. In the illustrated embodiment, the first support arm 38 is coupled to the base 40 at the first end 42 of the first support arm 38. As mentioned above, the mounting set 32 is in the stored position 36 in Figure 5. As a result, the first support arm 38 is in a substantially vertical orientation with respect to the ground. However, the first support arm 38 is configured to rotate around the first geometry axis 44. As discussed in detail below, the rotation of the first support arm 38 around the first geometry axis 44 changes the mounting assembly 32 between the stored position 36 and the operating position 76 in which the analyzer 34 is positioned at the rear of the implement 10 and close to the ground surface.
    [0029] [029] As mentioned above, the first support arm 38 rotates around the first geometry axis 44 to change the set 32 between stored position 36 and operating position 76. In the illustrated embodiment, actuator 46 drives the first control arm support 38 to rotate around the first geometry axis 44. As shown, actuator 46 is a hydraulic cylinder configured to extend and retract a piston coupled to the first support arm 38 to drive rotation around the first geometry axis 44. For example , when the piston is retracted the first support arm 38 is actuated towards the stored position 36 of the set 32 and when the piston is extended the first support arm 38 is actuated towards the operating position 76 of the set 32. However , it should be assessed that alternative linear actuators (eg helical transmissions, electromechanical actuators, etc.) can be employed in alternative designs. In additional embodiments, a rotary actuator (for example, hydraulic, electric, etc.) can be used. In certain embodiments, a gear and pulley system can be used to drive the rotation of the first support arm 38. In addition, as will be discussed in detail below, a control system can be included to control the operation of the actuator 46.
    [0030] [030] In the illustrated embodiment, the mounting set 32 includes the rotating member 48 pivotally coupled to the first support arm 38 at the second end 50. The rotating member 48 is configured to rotate about the second geometry axis 52. In addition , the rotation member 48 is coupled to the second support arm 54 at the first end 56 of the second support arm 54. The second support arm 54 is configured to rotate about the second geometry axis 52 with respect to the rotation of the first support arm. support 38. That is, the second support arm 54 rotates around the second geometry axis 52 with the rotating member 48. The second support arm 54 is configured to support analyzer 34 along the length of the second support arm 54 As a result, analyzer 34 is moved towards the rear position of the implement and close to the surface of the ground according to the first support arm 38 and the second support arm. support 54 are moved to operating position 76.
    [0031] [031] In the illustrated embodiment, the actuator 60 drives the second support arm 54 to rotate around the second geometry axis 52. As shown, the actuator 60 includes cables 61 that extend from the base 40 to the rotation member 48. The cables 61 drive the rotation member 48 to rotate around the second geometry axis 52 as the first support arm 38 rotates around the first geometry axis 44. That is, the tension in the cables 61 increases as the first support 38 rotates around the first geometry axis 44, and this tension is applied to the rotation member 48 to drive the rotation member 48 to rotate around the second geometric axis 52. As a result, the second support arm 54 also rotates around around the second geometrical axis 52. The cables 61 are formed from a non-electrically interactive material in the illustrated embodiment, as described in details above. However, in alternative embodiments, the cables 61 can be straps, ropes, or any material capable of applying force to the rotating member 48 and / or the second support arm 54.
    [0032] [032] In the illustrated embodiment, a frame 102 is pivotally coupled to the second support arm 54 by means of a frame connection 104. As shown, the frame connection 104 is a parallel connection system coupled to the second support arm 54 to the along the length of the second support arm 54. In certain embodiments, guides (for example, 90-degree pieces of non-electrically interactive material) can be attached to frame 102 to facilitate coupling to frame connection 104. For example, guides they can run the length of the frame 102. The analyzer 34 is coupled to the frame 102. The frame 102 is positioned on the second support arm 54 so that the frame 102 is in the retracted position 64 while the mounting set 32 is in the stored position 36 and in the lowered position 72 while the mounting set 32 is in the operating position 76 by means of rotation around the geometric axis of a frame 106. Consequently, the position d the frame 102 corresponds to the position of the second support arm 54. The frame 102 is configured to distribute the weight of the second support arm 54 and the analyzer 34 while the mounting set 32 is in the operating position 76. That is, the frame 102 is configured to allow low disturbance positioning of analyzer 34. In addition, frame 102 and frame connection 104 are sized to place analyzer 34 close to the surface of agricultural field 14 while mounting set 32 is in the operating position 76. In the illustrated embodiment, frame 102 and frame connection 104 are formed from a non-electrically interactive material. In addition, the fasteners (for example, fasteners that couple the frame 102 to the frame connection 104) are formed from non-electrically interactive material.
    [0033] [033] Figure 6 is a perspective view of the mounting set 32 in an intermediate position between the stored position 36 and the operating position 76. In the illustrated embodiment, the first support arm 38 rotates about the first geometric axis 44 , by means of actuator 46, in the first direction 66, thereby moving the second end 50 of the first support arm 38 in the longitudinal direction 68 which is opposite to the direction of travel 11 of the implement 10. According to the first support arm 38 rotates about the first geometrical axis 44, the second end 50 of the first support arm 38 is moved closer to the surface of the agricultural field 14. In addition, in the illustrated embodiment, the second support arm 54 is driven to rotate around the second geometric axis 52 in the second direction 70 by the actuator 60 (for example, the cables 61). As shown, the second direction 70 is opposite to the first direction. Consequently, rotation in the second direction 70 drives the second end 58 of the second support arm 54 to move in the direction 68. As a result, the mounting set 32 is elongated as the mounting set 32 changes to the operating position 76, thereby, moving the agricultural soil analyzer 34 to the rear.
    [0034] [034] As mentioned above, the second support arm 54 includes the frame 102 configured to switch between the retracted position 64 while the mounting set 32 is in the stored position 36 and the lowered position 72 while the mounting set 32 is in the position of operation 76. In the illustrated embodiment, the frame 102 rotates around the geometric axis of the frame 106 by means of the frame connection 104 as the second support arm 54 rotates around the second geometric axis 52 in the second direction 70. The frame 102 it is mounted on the second support arm 54 so that gravity pulls the frame 102 to the lowered position 72 as the mounting set 32 changes to the operating position 76. In addition, the frame 102 rotates back to the retracted position 64 as the assembly set 32 changes towards the stored position 36.
    [0035] [035] Figure 7 is a perspective view of the mounting set 32 in operating position 76. As described above, the first support arm 38 is driven around the first geometry axis 44 in the first direction 66 by the actuator 46. operating position 76, the first support arm 38 is substantially parallel to the surface of the agricultural field 14. In addition, the second support arm 54 is driven around the second geometry axis 52 in the second direction 70 by the actuator 60. As a result, the second support arm 54 is oriented substantially parallel to the surface of the agricultural field 14. In addition, the frame 102 makes contact with the surface of the agricultural field 14 to support the weight of the assembly set 32 in the operating position 76.
    [0036] [036] As shown, in the illustrated embodiment, the analyzer 34 is close to the surface of the agricultural field 14 while the mounting set 32 is in the operating position 76. In addition, the analyzer 34 is substantially parallel to the second support arm 54 and the direction of travel 11. As a result, analyzer 34 is positioned to emit and / or receive electromagnetic energy to / from the soil without making contact with the surface of the agricultural field 14 while analyzer 34 is pulled in the direction of travel 11. In addition furthermore, in the illustrated embodiment, the assembly set 32 extends in the direction 68. As illustrated, the assembly set 32 extends from the rear end of the implement 10 in a rear direction in relation to the travel direction 11 of the implement 10 The extension of the assembly set 32 is configured to longitudinally separate the analyzer 34 from the ferrous and / or electrically interactive components of the agricultural implement 1 to 10 thereby allowing the analyzer 34 to obtain readings with improved accuracy due to reduced interference from the electrically interactive components. In the illustrated embodiment, the analyzer 34 is positioned approximately 2.40 meters (8 feet) to the rear of the implement 10 in relation to the direction of travel 11. However, in other embodiments, the analyzer 34 may be further or closer. For example, mounting set 32 can position analyzer 34 to be between 1.5 meters (5 feet) and 6 meters (20 feet) from the implement 10. In addition, frame length 102 can be modified to support the assembly set 32 in realizations that have the sets 32 that extend greater distances from the implement 10. In addition, as described above, multiple assembly sets 32 and analyzers 34 can be coupled to the implement 10. For example , the mounting sets 32 can be mounted across the rear end of the implement 10.
    [0037] [037] Figure 8 is a block diagram of an embodiment of a control system 78 configured to control the movement of the assembly set 32 (for example, between stored position 36 and operating position 76). In the illustrated embodiment, the control system 78 includes a controller 80 that has a memory 82 and a processor 84 and a user interface 86. Memory 82 can be any type of non-transitory machine-readable media for storing executable data and instructions, such as random access memory, read-only memory, rewritable flash memory, hard drives, optical discs and the like. Processor 84 can execute instructions stored in memory 82. For example, memory 82 can contain machine-readable code, such as instructions, which can be executed by processor 84. In some embodiments, memory 82 and processor 84 may allow operation automatic (eg processor / memory controlled) assembly 32.
    [0038] [038] The operator can interact with user interface 86 to send an operation signal to controller 80. For example, the operator can press a button on user interface 86 that sends an operation signal to controller 80 indicative of a command to drive assembly 32 to operating position 76. As mentioned above, processor 84 can execute instructions stored in memory 82. Controller 80 is configured to send a control signal to hydraulic controller 88 to drive the mounting set 32 for operating position 76. For example, hydraulic controller 88 may include a valve that controls the flow of hydraulic fluid to actuator 46. Consequently, direct the valve to open and supply fluid to actuator 46 that drives the first support arm 38 to rotate in the first direction 66 around the first geometry axis 44. As described above, the rotation of the first support arm action 38 in the first direction 66 also triggers the rotation of the second support arm 54 in the second direction 70 through the actuator 60. Therefore, interaction with user interface 86 can change the assembly set 32 from the stored position 36 to the operating position 76. As will be evaluated, a similar operation can change the assembly set 32 from the operating position 76 to the stored position 36.
    [0039] [039] As shown in Figure 8, the data obtained by analyzer 34 is output to interface module 90. In some embodiments, interface module 90 includes an ISOBUS. However, in other embodiments, interface module 90 may include CANBUS, data processing software or the like. Interface module 90 receives data from analyzer 34. For example, in some embodiments, analyzer 34 can perform scan and record operations. Then, the data is transmitted in the ISOBUS of the interface module 90. In certain embodiments, the analyzer 34 can scan / record continuously (for example, through continuous analog signals, through a continuous digital data transmission, through digital data packets issued at discrete intervals, etc.) and output the data to interface module 90. In the illustrated embodiment, interface module 90 is communicatively coupled to a wireless transmitter 91, which is configured to output data for a wireless receiver 92. The wireless receiver 92 is communicatively coupled to a remote server 93, such as a memory or cloud data storage system. For example, data can be transferred using a cell phone signal, wireless network (for example, 3G, 4G, etc.) or the like. However, in other embodiments, data can be transferred via wired transmitters (for example, USB, category 5, etc.) or removable storage devices (for example, USB memory cards, portable hard drives, etc.). ). The transfer of data to the remote server 93 allows access to the data to facilitate the preparation of soil maps simultaneously with soil monitoring, thereby reducing the time between data acquisition and fertilization / planting operations. However, in other embodiments, software configured to generate three-dimensional maps of the field can be loaded into memory 82, and processor 84 can generate maps in real time / near real time during data acquisition. Consequently, fertilization / planting operations can be planned during data acquisition.
    [0040] [040] Figure 9 is a flow chart of an implementation of a method 94 to conduct data acquisition using the agricultural soil analyzer 34. The assembly set 32 is moved from the stored position 36 to the operating position. 76 in block 96. For example, actuator 46 can drive the rotation of the first support arm 38 in the first direction and actuator 60 can drive the rotation of the second support arm 54 in the second direction. In addition, in some embodiments, the control system 78 can send a signal to actuators 46 and 60 to control the rotation of the assembly set 32 between stored position 36 and operating position 76. As described above, analyzer 34 it is positioned at the rear of the implement and close to the surface of the agricultural field 14 in the operating position 76, thus allowing the acquisition of data. In addition, while the mounting set 32 is in the operating position, there is sufficient distance between the analyzer 34 and the electrically interactive components of the implement 10 to allow accurate measurements. The implement 10 is moved through the agricultural field 14 while the assembly set 32 is in the operating position on block 98. Analyzer 34 detects and records data while being towed through agricultural field 14. Then, the data obtained by analyzer 34 are transmitted to interface module 90 in block 100. For example, interface module 90 can transfer data to a database in the cloud via wireless transmitter 92. Or, in some embodiments, software stored in memory 82 and processor 84 can generate yield maps based on the data obtained by the analyzer 34.
    [0041] [041] As described in detail above, the disclosed achievements include an assembly set 32 configured to selectively position an agricultural soil analyzer 34 in operating position 76, thereby positioning the agricultural soil analyzer 34 longitudinally to the rear of the implement and close to the surface of the agricultural field 14. In certain embodiments, the mounting set 32 includes actuators 46 and 60 to drive the mounting set 32 between stored position 36 and operating position 76. For example, actuator 46 can drive the rotation of the first support arm 38 and the actuator 60 can trigger the rotation of the second support arm 54. While in operating position 76, the analyzer 34 emits electromagnetic energy to the ground and records the energy returned from the ground. The data obtained from the analyzer 34 is analyzed and a three-dimensional map of the soil can be generated to direct efficient planting or fertilization operations. In addition, data can be uploaded to a database (for example, remote cloud-based server) for further analysis. As a result, improvements in yield and efficiency of fertilization / planting can be achieved.
