[0002] Devices for dispensing at least one liquid medium; methods for dispensing at least one liquid medium

[0003] State of the art

[0004] The invention is based on 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 17, a device for dispensing at least one liquid medium, according to the preamble of claim 20, a method for dispensing at least one liquid medium, according to the preamble of claim 35, a device for dispensing at least one liquid medium, according to the preamble of claim 38, and a method for dispensing at least one liquid medium, according to the preamble of claim 40.

[0005] Particularly in agriculture, devices for applying at least one liquid medium, in particular irrigation machines, crop protection sprayers, or fertilization devices, have long been state of the art. Devices suitable for linear application are often equipped with a boom that folds together during transport and unfolds to achieve the maximum working width. For example, such devices are disclosed in published patent application DE 10 2016 109 513 A1 and patent application DE 10 2019 121 536 B4. The disadvantage here is that, in order to achieve large working widths, the foldable boom must unavoidably have a folding mechanism and be very robust, which makes the device very heavy. In addition to a folding mechanism for the boom, telescopic booms are also state of the art.Such devices are disclosed, for example, in published patent application DE 40 13 992 A1 and in international patent application WO 2009 / 046723 A1. 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 telescoping and retracting, in addition to the robust design of the individual segments, also contributes to the increased weight. Furthermore, such devices are usually attached or towed devices, so that increased ground pressure occurs during use due to the additional tractor required.

[0006] The invention is therefore based on the object of providing devices for dispensing at least one liquid medium which overcome the disadvantages of the prior art and methods for dispensing at least one liquid medium which overcome the disadvantages of the prior art.

[0073] Description of the embodiments

[0074] Fig. 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, crop protection agent or substrate mixed with fertilizer or liquid digestate. The device 1 according to the invention is preferably 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 determining its position, is preferably promoted by a rotatable independent wheel suspension 2. The independent wheel suspension 2 enables the device 1 according to the invention to be moved easily and without damaging the crop. It would also be conceivable, however, for the device 1 according to the invention to be a mounted device or a towed device.

[0075] The device 1 according to the invention, which can have a working width of, for example, 72 m, has a rod assembly formed from several rod sections 3, wherein each rod section 3 is formed from at least one rod part. In the exemplary embodiment shown, the device 1 according to the invention has a centrally arranged rod section 3 which is designed as a frame 4. Five rod sections 3, namely a first rod element 5, a second rod element 6, a third rod element 7, a fourth rod element 8 and a fifth rod element 9, are connected to the frame 4. To illustrate the telescoping of the five rod sections 3, Fig.1 the first rod element 5, the second rod element 6, the third rod element 7, the fourth rod element 8 and the fifth rod element 9 of the five rod sections 3 arranged on the left of the frame 4 are shown telescoped in and the first rod element 5, the second rod element 6, the third rod element 7 and the fourth rod element 8, in which the non-telescopic fifth rod element 9 is still located, of the five rod sections 3 arranged on the right of the frame 4 are shown telescoped out.

[0076] The liquid medium is applied using hanging 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, application is extremely loss-free. By telescoping, the hoses 13 are at least partially retracted into the respective boom sections 3. A section control serves to ensure that the liquid medium is not applied twice and to avoid collisions with obstacles.The device 1 according to the invention has a hose reel 12 for a hose 13, the height of which can be adjusted in order to avoid damage to higher plants 14 when adjusted upwards or to ensure compliance with the height limit in road traffic (e.g. 4 m) when lowering.

[0077] Fig. 2 shows a perspective rear view of the device 1 according to the invention, as shown in Fig. 1. The hose 13 can preferably be wound up and unwound from the hose reel 12, wherein the winding and unwinding of the hose 13 is preferably actively controlled, for example electrically or hydraulically, in both cases. If the device 1 according to the invention is a sprinkling device, the free end of the hose 13 is preferably connected to a hydrant. To ensure that the hose 13 connected to the hydrant is held in place, a fastening weight 15 is lowered onto the hydrant using a hydraulic pick-up control and anchored in the ground. Using the hydraulic pick-up control, the anchored fastening weight 15 can be picked up again by the sprinkling device and transported to the next hydrant. It is also conceivable for the free end of the hose 13 to be connected to a tank or to end in an open body of water.

[0078] Fig. 3 shows a perspective detailed view of the front of the device 1 according to the invention, as shown in Fig. 1. The device 1 according to the invention comprises a cabin 16, a motor 17, which is preferably an electric motor or a diesel engine with, for example, 36 kW, and wheels 18, which are preferably individually driven and steerable by the motor 17. Hydraulic cylinders 19 are arranged between the frame 4 and the first linkage element 5, by the actuation of which the inclination of the linkage element 5 can be adjusted. This results in an inclination adjustment.

[0079] Fig. 4 shows a perspective detailed view of the right side of the device 1 according to the invention, as shown in Fig. 1. The device 1 according to the invention comprises a device frame 20 and a vertical height adjustment for the rods. For the vertical height adjustment, hydraulic cylinders 21 are arranged between the device frame 20 and the frame 4; their actuation allows the height of the frame 4 to be adjusted.

[0080] Fig. 5 shows a perspective detailed view of the height adjustment for the rods of the device 1 according to the invention, according to Fig. 1. With the help of the two hydraulic cylinders 21, the frame 4 and thus the rods arranged on it can be adjusted in its vertical height in order to protect the crop to be irrigated, e.g. the plant 14, and to set the optimal height for the irrigation process. During the up or down movement, the hydraulic cylinders 21 displace a lifting mast 22 on which the frame 4 is mounted. The lifting mast 22 is also connected to the device frame 20. For this purpose, the device frame 20 has a plurality of bearing rollers which run in a slide rail 23 arranged on the lifting mast 22 and facilitate the adjustment of the frame 4.

[0081] Fig. 6 shows a perspective detailed view of the height adjustment, according to Fig. 5. The bearing roller is connected to the device frame 20 by a bearing roller attachment 24.

[0082] Fig. 7 shows a perspective detailed view of a folding mechanism for the rods of the device 1 according to the invention, according to Fig. 1. In order to transfer the device 1 according to the invention from a working position into a transport position, the device 1 according to the invention is equipped with a folding mechanism which operates with two hydraulic cylinders 25. Both hydraulic cylinders 25 are arranged on the one hand on a movable frame part 26 and on the other hand on a movable frame part 27. The movable frame part 26 is arranged on the left of the frame 4 and can be pivoted about an axis 28 and is connected to the first rod element 5, which is located to the left of the frame 4. The movable frame part 27 is arranged on the right of the frame 4 and can be pivoted about an axis 29 and is connected to the first rod element 5, which is located to the right of the frame 4.Thus, when the two hydraulic cylinders 25 are extended, the movable frame part 26, together with the first linkage element 5 arranged on 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 arranged on it, rotates counterclockwise around the axis 29 to reach the transport position. When the two hydraulic cylinders 25 are retracted, the movable frame part 26, together with the first linkage element 5 arranged on 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 arranged on it, rotates clockwise around the axis 29 to reach the working position.

[0083] Fig. 8 shows a perspective view of the device 1 according to the invention, as shown in Fig. 1, in the transport position. Fig. 9 shows a detailed view of an inclination adjustment for the rod assembly of the device 1 according to the invention, as shown in Fig. 1. The inclination of the two booms is adjusted by a total of four lifting cylinders 19, two on each side. The two lifting cylinders 19, which are responsible for adjusting the inclination of the left boom, are arranged between the movable frame part 26 and the first rod element 5, which is located to the left of the frame 4, and the two lifting cylinders 19, which are responsible for adjusting the inclination of the right boom, are arranged between the movable frame part 27 and the first rod element 5, which is located to the right of the frame 4. A downward pivoting of a boom is achieved by the hydraulic cylinders 19 used for pivoting not being fully retracted in the horizontal state.Retraction of the hydraulic cylinder 19 therefore results in a boom being able to be tilted downwards.

[0084] Since the vertical axis 28 of the folding mechanism 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, it is irrelevant during folding which inclination state the booms are in, since the hydraulic cylinders 19 responsible for this are located between the movable frame part 26 and the boom arranged to the left of the frame 4 and between the movable frame part 27 and the boom arranged to the right of the frame 4, so that the hydraulic cylinders 19 are pivoted when the booms are folded from a working position into a transport position or from a transport position into a working position.

[0085] Fig. 10 shows a detailed view of the inclination adjustment, as shown in Fig. 9. By actuating the lifting cylinders 19, the inclination of each boom side can be adjusted, for example, to adapt to a terrain profile. As shown for the right boom as an example, the right boom rotates around an axis of a pin connection 30 and an axis of a pin connection 31.

[0086] Fig. 11 shows a detailed view of a height adjustment of a hose reel 12 of the device 1 according to the invention, as shown in Fig. 1. Using hydraulic cylinders 32, the hose reel 12, which is mounted on support frames 33 pivotably mounted on the implement frame 20, can be lifted over, for example, a corn crop. This prevents damage to the plants 14 and eliminates the need for additional tramlines. Furthermore, the hydraulic adjustment allows the overall height of 4 m to be maintained in road traffic.

[0087] Fig. 12 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate a flow direction of a medium in a hose reel 12, indicated by an arrow 34. Through the hose 13, which can be connected to a hydrant, for example, or supplied from an open body of water by means of an external pump, the medium reaches 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, from where it reaches the two support frames 33 of the hose reel 12 in the direction of the arrow 38. The medium is thus guided on both sides by the two support frames 33 of the hose reel 12.

[0088] Fig. 13 shows a detailed view of the device 1 according to the invention, according to Fig. 1, to clarify a flow direction of a medium in a support frame 33, shown with an arrow. The medium flows in the direction of the arrow 39 over the hollow support frames 33 until it finally reaches the rod section 3 via a nozzle 40 and a hose (not shown in Fig. 13), through which it flows in the direction of the arrow 41, and / or a hose (not shown in Fig. 13), through which it flows in the direction of the arrow 41, into the frame 4 or to the hoses arranged on the frame 4.

[0089] Fig. 14 shows a detailed view of the flow direction, according to Fig. 13.

[0090] Fig. 15 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate a flow direction of a medium in a support frame 33, indicated by an arrow 41. Fig. 16 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate a media transfer into the right-hand rod half, indicated by an arrow 42. A media transfer from one rod half to a nozzle arranged on the frame 4 is also conceivable.

[0091] Fig. 17 shows a detailed view of the hose reel 12. The rotary joint is sealed by a bearing system with various shaft seals and to the outside by a screwable maintenance cover 43.

[0092] Fig. 18 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, illustrating a fastening weight 15. The fastening weight 15 is a hydraulically mountable fastening weight 15, with the aid of which a hose end 44 of the hose 13 is secured to the ground near a hydrant (not shown). So-called ground anchors 46 on the fastening weight 15 assist in this process. A first hose guide 47 is also mounted on the holder for the fastening weight 15, which is hydraulically adjustable via lifting cylinders 46. The direction of flow of the medium is indicated by the arrow 48.

[0093] Preferably, the hose reel 12 is an active reel, which is driven by a hydraulic motor proportional to the driving speed when rewinding the hose 13. When the hose 13 is unwinding, the hose reel 12 is braked by the hydraulic motor to prevent uncontrolled unwinding of the hose 13.

[0094] Fig. 19 shows a detailed view of the device 1 according to the invention, according to Fig. 1, to illustrate the hose guide 48. The hose guide 47 is adjustable in height by the two hydraulic cylinders 46 and enables an adjustment of the hose support to the floor.

[0095] Fig. 20 shows a further detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate the hose guide 47. With the aid of 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. Fig. 21 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate the media guide in the direction of the arrows 52 in the telescopic rod.

[0096] Fig. 22 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, of media-carrying profile pipes. After the medium has been transferred through the two hoses arranged on the nozzles 40 into the rod section 3, the liquid media is passed on in the direction of arrow 54 via the two lower profile pipes 53 (e.g., rectangular profile pipes), which represent rod sections. With the help of the two hydraulic cylinders 19, the rod can be adjusted in its inclination to suit different ground conditions.

[0097] Fig. 23 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate a flow direction of a medium on the first rod element 5, indicated by an arrow 54. These profile tubes 53, as part of the rod assembly, are both static elements and are made of a material that is resistant to the medium. Cross struts 55 between the two lower profile tubes 53 distribute the medium evenly in the rod assembly. The connections 56 of the individual outlets for nozzles 11 and hoses 10 are attached to one of the lower profile tubes 53 in the first rod element 5. The distances between the individual outlets can be freely selected. The outlets for the nozzles are preferably arranged on the cross struts 55.It is also conceivable that not all of the rod elements or no rod element is flowed through by the medium, so that a line, in particular a pipe arranged on the cross struts 55 or another rod part, for the medium is arranged on the rod element or the rod elements not flowed through. Preferably, a line is arranged below a rod element. To enable telescoping, a supply hose is used to convey the medium from a line arranged on one rod element to the next rod element or to a line arranged on the next rod element or from a rod element through which the medium flows to a line arranged on the next rod element.A flat hose is preferably used as the supply hose because, due to its flexible properties, it can bend in a tight radius, which simultaneously interrupts the media transfer to the next element when the rod is telescoped in.

[0098] Fig. 24 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate the route of a supply hose 57. The supply hose 57, which is arranged on the one hand on the nozzle 58 and on the other hand on the nozzle 59, serves to convey the medium to the next boom element. A flat hose is preferably used as the supply hose 57 because, due to its flexible properties, it can bend in a tight radius, which simultaneously interrupts the flow of medium to the next element when the boom is telescoped in. This also enables section switching to prevent double application of the same medium in the field.

[0099] Fig. 25 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate the storage of nozzles and hoses in the telescopically retracted state. Since the nozzles 11 can optionally be attached to hoses 10, these must be stowed away when telescoping. This is made possible by a folded trough 60 in the rod assembly. For this purpose, the hoses 10 bend at the inlet of the trough 60 and can thus lie flat in it. Trouble-free bending is ensured by a rounded inlet 61 on the trough 60. The trough 60, into which both the supply hose 57 (e.g. flat hose) and the nozzles are placed, is not shown in Fig. 24 to clarify the hose route.

[0100] Fig. 26 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate a latch system for locking individual elements in the rod assembly. The latch system, which has upper latches 62 and lower latches 63, serves to lock the individual elements from being extended and retracted. The individual elements of the rod assembly are locked by the latches 62 and 63 of the latch system. Fig. 27 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate a state of the second rod assembly element 6, with the additional elements located inside, which is extended from the first rod assembly element 5. After the booms have been moved from the transport position into the working position by the folding mechanism, one boom can be telescoped out. The telescoped out process is illustrated by way of example using the right-hand boom shown in Fig. 27.At the beginning of the telescoping, the second rod element 6 with the other locked rod elements 7, 8 and 9 moves in the direction of the arrow 64 out of the pivoted first rod element 5, which is connected to the frame 4.

[0101] Fig. 28 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, to illustrate the release of the third rod element 7 by the second rod element 6. In Fig. 28, the third rod element 7 is shown already extended. As soon as the upper pawl 62 of the second rod element 6 reaches a last bar 65 of the first rod element 5, the third rod element 7 is released and can then extend. The third rod element 7 is thus released from the second rod element 6. If the third rod element 7 now extends, the lower pawl 63 of the second rod element 7 tilts and thus prevents an uncontrolled retraction of the second rod element 7. This procedure can be applied to the other telescopic elements. Telescoping takes place in the reverse order. This ensures that each element is individually telecopied or extended according to the order.

[0102] Fig. 29 shows a detailed view of the device 1 according to the invention, according to Fig. 1, to illustrate a fixing of the second rod element 6. By telescoping out the third rod element 7 and tilting the lower pawl 63 of the second rod element 6, the lower pawl 63 is fastened with its lower pawl part 66 to a bar 67 of the first rod element 5, whereby a telescoping in of the second rod element 6 is prevented as long as the third rod element 7 has not been telescoped in again, whereby the lower pawl 63 would be released from the rust by tilting. The rod parts carrying a liquid medium, e.g. the profile tubes 53, the cross struts 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 struts 69 are arranged on the profile tubes 53.Thus, direct contact with the profile tubes 53 carrying a liquid medium and the connecting struts 69, which are preferably made of steel, is avoided.

[0103] Fig. 30 shows a detailed view of the device 1 according to the invention, according to Fig. 1, to illustrate a traction winch 70. The traction winch 70, which forms a cable pull mechanism and can be hydraulically or electrically driven, is used to telescope a boom in and out. For this purpose, the cable pull mechanism has a cable 71, the two cable ends of which take over the telescope in and out depending on the direction of rotation of the traction winch 70. A traction winch 70 is a through-run winch without cable take-up or cable storage and with two opposing cable pulleys. The number of grooves on the cable pulleys and the cable wound around them increases the frictional force and thus the tensile force or counterforce. This prevents the cable from spinning on the cable pulleys and a power transmission from the hydraulic or electric drive to the cable takes place. The pulling direction of the cable ends changes depending on the direction of rotation of the drive.The rope is guided to the traction winch through various deflections. These rope ends are each attached to a compression spring system on the last telescopic element of the rod. This compression spring system ensures smooth rope start-up.

[0104] The use of a capstan winch is also conceivable. Like traction winches, capstan winches are continuous winches. Capstan winches do not store any rope on the rope drum. An "endless" rope is guided multiple times around just one driven capstan head (instead of two rope pulleys for a traction winch) of the drive (electric or hydraulic). As with a traction winch, the multiple wraps multiply any applied counterforce or tensile force. Since the rope in the case of a capstan winch is only wound around one drum / capstan head, the rope must be able to move sideways during winding. The disadvantage of this is the friction of the rope against each other and the resulting increased wear. Nevertheless, it is an option for driving the retraction and extension of the boom. For this reason, it is often used in forestry with a textile rope. Fig. 31 shows a sketch of a deflection system for the rope guide in a boom.The rope 71 can be divided into an upper rope 72, which has a rope end 73, and a lower rope 74, which has a rope end 75. The lower rope 74 is connected to the fifth rod element 9 at the end and is responsible for telescoping. The lower rope 74, which is guided over deflection pulleys 76, is connected to the fifth rod element 9 via a compression spring system 77, which enables smooth telescoping. The rope end 73 of the upper rope 72 is responsible for telescoping the rod. The upper rope 72 is guided over variously arranged deflection pulleys 78, which enable telescoping. The upper rope 72, which is responsible for telescoping, is also attached to the fifth rod element 9 via a compression spring system 79. This system works in the opposite direction to the compression spring system 77, which is responsible for telescoping.For reasons of clarity, a traction winch or capstan winch has been omitted.

[0105] Fig. 32 shows a detailed view of the device 1 according to the invention, according to Fig. 1, to illustrate the compression spring systems 77 and 79 for both rope ends.

[0106] Fig. 33 shows a detailed view of the device 1 according to the invention, as shown in Fig. 1, illustrating a cable guide on the boom. A traction winch 70 is shown as an example.
