Description

State of the art

[0001] The invention relates to a device for dispensing at least one liquid medium according to the preamble of claim 1, a method for dispensing at least one liquid medium according to the preamble of claim 18, a device for dispensing at least one liquid medium according to the preamble of claim 21, a method for dispensing at least one liquid medium according to the preamble of claim 38, a device for dispensing at least one liquid medium according to the preamble of claim 41, and a method for dispensing at least one liquid medium according to the preamble of claim 44.

[0002] Particularly in agriculture, devices for applying at least one liquid medium, especially irrigation machines, crop protection sprayers, or fertilization equipment, have long been considered state of the art. Devices suitable for linear application are often equipped with a boom that folds down for transport and unfolds to achieve the maximum working width. A disadvantage of this design is that achieving large working widths inevitably requires a folding mechanism and a very robust construction of the boom, making the device quite heavy.

[0003] Besides a folding boom mechanism, telescopic booms are also considered state of the art. With these devices, the boom is first unfolded, and then the individual segments (boom sections) are hydraulically extended to the desired working width (e.g., 66 m). However, the hydraulic system used for extending and retracting, in addition to the robust design of the individual segments, also contributes to the increased weight. Furthermore, such devices are generally mounted or towed implements, so their use results in increased ground pressure due to the additional tractor required.

[0004] The invention is therefore based on the objective of providing devices for the dispensing of at least one liquid medium and methods for the dispensing of at least one liquid medium that overcome the disadvantages of the prior art. The invention and its advantages

Description of the exemplary implementations

[0047] Fig. Figure 1 shows a perspective front view of a device 1 according to the invention. The device 1 according to the invention serves to apply at least one liquid medium, in particular water, liquid fertilizer, plant protection products, or substrate mixed with fertilizer or liquid digestate. Preferably, the device 1 according to the invention is a self-propelled device, in particular an autonomously driving self-propelled device. The mobility of the device 1 according to the invention, which preferably uses the global positioning system (GPS) for position determination, is preferably enhanced by a rotatable independent wheel suspension 2. The independent wheel suspension 2 enables easy and crop-friendly relocation of the device 1 according to the invention. However, it would also be conceivable for the device 1 according to the invention to be a mounted device or a towed device.

[0048] The device 1 according to the invention, which can have a working width of, for example, 72 m, comprises a boom formed from several boom sections 3, wherein a boom section 3 is formed from at least one boom part. In the illustrated embodiment, the device 1 according to the invention has a centrally arranged boom section 3, which is designed as a frame 4. Five boom sections 3 are connected to the frame 4, namely a first boom element 5, a second boom element 6, a third boom element 7, a fourth boom element 8, and a fifth boom element 9. To illustrate the telescoping capability of each of the five boom sections 3, the following are shown in Fig. 1 The first linkage element 5, the second linkage element 6, the third linkage element 7, the fourth linkage element 8 and the fifth linkage element 9 of the five linkage sections 3 arranged on the left of the frame 4 are shown telescoped in, and the first linkage element 5, the second linkage element 6, the third linkage element 7 and the fourth linkage element 8, in which the un-telescoped fifth linkage element 9 is still located, of the five linkage sections 3 arranged on the right of the frame 4 are shown telescoped in.

[0049] The liquid medium is applied using suspended hoses 10, optionally below or above the plant leaves, optionally with or without nozzles 11, using a low-pressure method. Preferably, the pressure in the boom is approximately 4 bar and at the nozzle approximately 0.75 to 1 bar, so that the device 1 according to the invention is very energy-efficient due to the low pressure and has a flow loss of only approximately 3 bar. Since the device 1 according to the invention does not apply the liquid medium by throwing, which would be associated with a 40 to 50% loss, the application is extremely low-loss. By telescoping, the hoses 13 are at least partially retracted into the respective boom sections 3. A section control system serves to prevent the liquid medium from being applied twice and to avoid collisions with obstacles.The device 1 according to the invention has a hose reel 12 for a hose 13, which can be adjusted in height in order to avoid damage to taller plants 14 when adjusting upwards, or to ensure compliance with the height limit in road traffic (e.g. 4 m) when lowering.

[0050] Fig. Figure 2 shows a perspective rear view of the device 1 according to the invention. Fig. 1. The hose 13 can preferably be wound and unwound from the hose reel 12, the winding and unwinding of the hose 13 being preferably actively controlled, e.g., electrically or hydraulically, in both cases. If the device 1 according to the invention is an irrigation device, the free end of the hose 13 is preferably connected to a hydrant. To secure the hose 13 connected to the hydrant, a securing weight 15 with a hydraulic retraction mechanism is lowered from the hydrant and anchored in the ground. The anchored securing weight 15 can then be retrieved by the irrigation device using the hydraulic retraction mechanism and transported to the next hydrant. It is also conceivable that the free end of the hose 13 is connected to a tank or terminates in an open body of water.

[0051] Fig. Figure 3 shows a perspective detail view of the front of the device 1 according to the invention. Fig. 1. The device 1 according to the invention comprises a cabin 16, a motor 17, preferably an electric motor or a diesel engine with, for example, 36 kW, and wheels 18, which are preferably individually driven by the motor 17 and are steerable. Hydraulic cylinders 19 are arranged between the frame 4 and the first linkage element 5, the actuation of which allows the inclination of the linkage element 5 to be adjusted. This results in an inclination adjustment.

[0052] Fig. Figure 4 shows a perspective detail view of the right side of the device 1 according to the invention. Fig. 1. The device 1 according to the invention comprises a device frame 20 and a vertical height adjustment for the linkage. For the vertical height adjustment, hydraulic cylinders 21 are arranged between the device frame 20 and the frame 4, by actuating which the height of the frame 4 can be adjusted.

[0053] Fig. Figure 5 shows a perspective detail view of the height adjustment for the linkage of the device 1 according to the invention. Fig. 1. The frame 4, and thus the linkage attached to it, can be adjusted vertically using the two hydraulic cylinders 21 to protect the crop being irrigated, e.g., the plant 14, and to set the optimal height for the irrigation process. During their upward or downward movement, the hydraulic cylinders 21 move a lifting mast 22 to which the frame 4 is mounted. The lifting mast 22 is also connected to the equipment frame 20. For this purpose, the equipment frame 20 has several bearing rollers that run in a guide rail 23 arranged on the lifting mast 22, facilitating the adjustment of the frame 4.

[0054] Fig. Figure 6 shows a perspective detail view of the height adjustment, according to Fig. 5. The bearing roller is connected to the device frame 20 by means of a bearing roller fastening 24.

[0055] Fig. Figure 7 shows a perspective detail view of a folding mechanism for the linkage of the device 1 according to the invention. Fig. 1. To transfer the device 1 according to the invention from a working position to a transport position, the device 1 according to the invention is equipped with a folding mechanism that operates with two hydraulic cylinders 25. Both hydraulic cylinders 25 are arranged on one side on a movable frame part 26 and on the other side on a movable frame part 27. The movable frame part 26 is pivotable about an axis 28 and is arranged on the left side of the frame 4 and is connected to the first linkage element 5, which is located to the left of the frame 4. The movable frame part 27 is pivotable about an axis 29 and is arranged on the right side of the frame 4 and is connected to the first linkage element 5, which is located to the right of the frame 4.Thus, when the two hydraulic cylinders 25 are actuated for extension, the movable frame part 26, together with the first linkage element 5 attached to it, rotates clockwise around the axis 28 to reach the transport position, and the movable frame part 27, together with the first linkage element 5 attached to it, rotates counterclockwise around the axis 29 to reach the transport position. When the two hydraulic cylinders 25 are actuated for retraction, the movable frame part 26, together with the first linkage element 5 attached to it, rotates counterclockwise around the axis 28 to reach the working position, and the movable frame part 27, together with the first linkage element 5 attached to it, rotates clockwise around the axis 29 to reach the working position.

[0056] Fig. Figure 8 shows a perspective view of the device 1 according to the invention. Fig. 1, in transport position.

[0057] Fig. Figure 9 shows a detailed view of a tilt adjustment for the linkage of the device 1 according to the invention. Fig. 1. The tilt adjustment of the two booms is achieved by a total of four lifting cylinders 19, two on each side. The two lifting cylinders 19 responsible for tilting the left boom are located between the movable frame section 26 and the first linkage element 5, which is located to the left of the frame 4. The two lifting cylinders 19 responsible for tilting the right boom are located between the movable frame section 27 and the first linkage element 5, which is located to the right of the frame 4. A boom can be tilted downwards by leaving the hydraulic cylinders 19 used for tilting partially retracted in the horizontal position. Retracting a hydraulic cylinder 19 therefore allows a boom to be tilted downwards.

[0058] Since, in the folding mechanism, the vertical axis 28 is located between the frame 4 and the movable frame part 26, and the vertical axis 29 is located between the frame 4 and the movable frame part 27, the tilt state of the booms is irrelevant during folding, as the hydraulic cylinders 19 responsible for this are located between the movable frame part 26 and the boom located to the left of the frame 4, and between the movable frame part 27 and the boom located to the right of the frame 4, so that the hydraulic cylinders 19 are pivoted along with the booms when they are folded from a working position to a transport position or from a transport position to a working position.

[0059] Fig. Figure 10 shows a detailed view of the tilt adjustment, according to Fig. 9. By actuating the lifting cylinders 19, the inclination of each linkage side can be adjusted, for example, to adapt to a terrain profile. As shown by the right boom, the right boom rotates about one axis of a bolted connection 30 and the other axis of a bolted connection 31.

[0060] Fig. Figure 11 shows a detailed view of a height adjustment of a hose reel 12 of the device 1 according to the invention. Fig. 1. Using hydraulic cylinders 32, the hose reel 12, which is mounted on support frames 33 that are pivotably attached to the equipment frame 20, can be lifted over, for example, a field of corn. This prevents damage to the plants 14 and eliminates the need for additional tramlines. Furthermore, the hydraulic adjustment ensures that the overall height of 4 m is maintained in road traffic.

[0061] Fig. Figure 12 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates the flow direction of a medium in a hose reel 12, shown by arrow 34. The medium flows through the hose 13, which may be connected to a hydrant or end in an open body of water, to a nozzle 35 that projects into the interior of a shaft 36 of the hose reel 12. The medium flows through this shaft 36 to a specially sealed rotary joint 37 at both ends of the shaft 36, and from there, in the direction of arrow 38, into the two support frames 33 of the hose reel 12. The medium is thus guided on both sides by the two support frames 33 of the hose reel 12.

[0062] Fig. Figure 13 shows a detailed view of the device 1 according to the invention. Fig. 1. To illustrate the flow direction of a medium in a support frame 33, represented by an arrow. The medium continues to flow in the direction of arrow 39 over the hollow support frames 33 until it finally exits through a nozzle 40 and a [missing element] in [missing element]. Fig. 13 hose not shown, through which it flows in the direction of arrow 41, into the linkage section 3.

[0063] Fig. Figure 14 shows a detailed view of the flow direction, according to Fig. 13.

[0064] Fig. Figure 15 shows a detailed view of the device 1 according to the invention. Fig. 1, to illustrate the direction of flow of a medium in a support frame, represented by an arrow 41.

[0065] Fig. Figure 16 shows a detailed view of the device 1 according to the invention. Fig. 1, to illustrate a media transfer into the right half of the rod, represented by an arrow 42.

[0066] Fig. Figure 17 shows a detailed view of the hose reel 12. The rotary connection is sealed by a bearing system with various shaft seals and to the outside by a screwable maintenance cover 43.

[0067] Fig. Figure 18 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates a securing weight 15. The securing weight 15 is a hydraulically liftable weight used to secure a hose end 44 of the hose 13 to the ground near a hydrant (not shown). Ground anchors 46 on the securing weight 15 assist in this process. A first hose guide 47 is also mounted on the hydraulically adjustable mounting for the securing weight 15, which is controlled by a lifting cylinder 46. The arrow 48 indicates the direction of flow of the medium.

[0068] Preferably, the hose reel 12 is an active winder which, when winding the hose 13, is driven proportionally to the travel speed by a hydraulic motor. When unwinding the hose 13, the hose reel 12 is braked by the hydraulic motor to prevent uncontrolled unwinding of the hose 13.

[0069] Fig. Figure 19 shows a detailed view of the device 1 according to the invention. Fig. 1, to illustrate the hose guide 48. The hose guide 47 is adjustable in height by the two hydraulic cylinders 46 and allows the hose storage to be adjusted to the ground.

[0070] Fig. Figure 20 shows a further detailed view of the device 1 according to the invention. Fig. 1, to illustrate the hose routing 47. Using a coupling system 49, a flexible hose 50 connects the hose 13 (plastic hose of the irrigation machine) to a hydrant connection 51 of any hydrant.

[0071] Fig. Figure 21 shows a detailed view of the device 1 according to the invention. Fig. 1, to clarify the media routing in the direction of arrows 52 in the telescopic rod.

[0072] Fig. Figure 22 shows a detailed view of the device 1 according to the invention. Fig. 1, onto media-carrying profile tubes. After the medium is transferred through the two hoses arranged at the nozzles 40 into the boom section 3, the liquid media are conveyed via both lower profile tubes 53 (e.g., rectangular profile tubes), which represent boom sections, in the direction of arrow 54. The boom's inclination can be adjusted to different ground conditions using the two hydraulic cylinders 19.

[0073] Fig. Figure 23 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates the flow direction of a medium at the first rod element 5, shown by an arrow 54. These profile tubes 53, as rod components, simultaneously serve as structural elements and are made of a medium-resistant material. Cross braces 55 between the two lower profile tubes 53 distribute the medium evenly throughout the rod. The connections 56 of the individual outlets for nozzles 11 and hoses 10 are located on one of the lower profile tubes 53 in the first rod element 5. The spacing of the individual outlets is freely selectable.

[0074] Fig. Figure 24 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates the path of a supply hose 57. The supply hose 57, which is connected to the nozzle 58 on one side and the nozzle 59 on the other, serves to convey the medium to the next boom section. A flat hose is preferably used as the supply hose 57 because, due to its flexible properties, it can bend in a tight radius, thereby interrupting the flow of the medium to the next section when the boom is extended. This also enables section control to prevent the double application of the same medium in the field.

[0075] Fig. Figure 25 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates the storage of nozzles and hoses in the retracted position. Since the nozzles 11 can optionally be attached to hoses 10, these must be stowed away when the telescope is retracted. This is made possible by a bent tray 60 in the frame. The hoses 10 bend at the entrance of the tray 60 and can thus lie flat inside it. A rounded entrance 61 on the tray 60 ensures that the hoses bend smoothly.

[0076] Fig. Figure 26 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates a latching system for locking individual elements in the linkage. The latching system, comprising upper latches 62 and lower latches 63, serves to lock the individual elements in and out. The latches 62 and 63 of the latching system lock the individual elements of the linkage.

[0077] Fig. Figure 27 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates the state of the second linkage element 6, with its internal components, extended from the first linkage element 5. After the booms have been moved from the transport position to the working position by the folding mechanism, one boom can be extended. The extension process is demonstrated using the example shown in Figure 1. Fig. The right boom shown in Figure 27 illustrates this. At the beginning of the extension, the second linkage element 6, together with the other locked linkage elements 7, 8 and 9, moves in the direction of arrow 64 from the swung-out first linkage element 5, which is connected to the frame 4.

[0078] Fig. Figure 28 shows a detailed view of the device 1 according to the invention. Fig. 1, to illustrate the activation of the third linkage element 7 by the second linkage element 6. In Fig. Figure 28 shows the third linkage element 7 already extended. As soon as the upper latch 62 of the second linkage element 6 engages the last spar 65 of the first linkage element 5, the third linkage element 7 is unlocked and can then extend. The third linkage element 7 is thus unlocked by the second linkage element 6. When the third linkage element 7 extends, the lower latch 63 of the second linkage element 7 tilts, preventing uncontrolled retraction of the second linkage element 7. This procedure can be applied to the other telescopic elements. Retraction is performed in reverse order. This ensures that each element is extended or retracted individually in the correct sequence.

[0079] Fig. Figure 29 shows a detailed view of the device 1 according to the invention. Fig. 1, to illustrate the locking of the second linkage element 6. By extending the third linkage element 7 and tilting the lower pawl 63 of the second linkage element 6, the lower pawl 63 engages with its lower pawl part 66 on a spar 67 of the first linkage element 5, thus preventing the second linkage element 6 from being retracted until the third linkage element 7 has been retracted, which would cause the lower pawl 63 to be released from the locking position by tilting.

[0080] The rod components carrying a liquid medium, e.g., the profile tubes 53, the cross braces 55, and the nozzles 58 and 59, are preferably made of stainless steel. Transition pockets 68 serve as corrosion protection, by means of which connecting braces 69 are arranged on the profile tubes 53. This avoids direct contact between the profile tubes 53 carrying a liquid medium and the connecting braces 69, which are preferably made of steel.

[0081] Fig. Figure 30 shows a detailed view of the device 1 according to the invention. Fig. Figure 1 illustrates a traction winch 70. The traction winch 70, which forms a cable-pulling mechanism and can be hydraulically or electrically driven, serves to extend and retract a boom. For this purpose, it has a cable 71, the two ends of which, depending on the direction of rotation of the traction winch 70, perform the extension and retraction.

[0082] Fig. Figure 31 shows a sketch of a deflection system for the cable guidance in a boom. The cable 71 can be divided into an upper cable 72, which has a cable end 73, and a lower cable 74, which has a cable end 75. The lower cable 74 is connected at its end to the fifth linkage element 9 and is responsible for retraction. The connection of the lower cable 74, which is guided over pulleys 76, to the fifth linkage element 9 is made via a compression spring system 77, thus enabling smooth telescoping. The cable end 73 of the upper cable 72 is responsible for extending the boom. The upper cable 72 is guided over differently arranged pulleys 78, which facilitate extension. The upper cable 72, responsible for extending the telescope, is also attached to the fifth linkage element 9 by a compression spring system 79.This system works in the opposite direction to the compression spring system 77, which is responsible for telescoping.

[0083] Fig. Figure 32 shows a detailed view of the device 1 according to the invention. Fig. 1, to illustrate the compression spring systems 77 and 79 for both rope ends.
