    FIELD OF THE INVENTION
    The present invention relates to a spreading boom for distribution of organic liquid fertilizers or plant protection agents, such as manure by means of a tractor-drawn or self-propelled tanker, and preferably in the form of a tow hose boom, which comprises a main frame and two side wings mounted thereon which are divided into several sections which are pivotable for switching between a transport position, wherein the side wings are arranged in planes substantially parallel to the direction of movement of the slurry tanker and a working position where at least part of the sections of the side wings are pivoted to a position substantially perpendicular to the transport position , which also includes a hose holder on which application hoses are mounted and a hydraulic system with actuators for pivoting the sections of the boom.
    BACKGROUND OF THE INVENTION
    The invention relates to a tool for distributing organic liquid fertilizers such as manure by means of a tractor-drawn or self-propelled tanker. The implement has at least one side wing divided into several foldable sections, to which hose holders are mounted, where hoses with outlet are attached. The hose outlets allow the distribution of manure to be streaked at a specified distance in the field. It is noted that a side wing in the subject is also referred to as a wing.
    In order to limit pollution of the air environment and enable fertilizer allocation in growing crops without corresponding contamination of the plants with harmful microorganisms, the aim is to bring the hose outlet of the implement into close contact with the soil surface.
    It is a well-known technical solution that has given similar tools the name tow hose bar. The down-to-earth application of the fertilizer helps to limit the emission, spread of the bacteria and microbes of the disease and increase the fertilizer uptake of the plants.
    DK 2016 70924 A1
    Trailer hose bars preferably work with distributors, either a main distributor or several decentrally located distributors, which are supplied at the entrance opening with fertilizer from the tank by means of a spreading pump or an overpressure in the tank from an air compressor. A number of hoses are connected to each manifold and the manifolds ensure an even distribution of fertilizer through the hose outlets to the field. In the application of the fertilizer itself, the sections of the side wings, with the aid of the hose holders, have the task of placing the hose outlets at a certain evenly spaced distance from one another as they are dragged across the ground. As the tanker is moved forward in a forward direction in the field, the fertilizer is thereby placed in the field streaked and made available to the growing crops.
    A tow hose boom with these characteristics is known, among other things, from the use pattern description DE 297 15 481 Ul. This describes a tow hose boom with at least two distributors and two side wings. In that case, the advantages have a special cutting device capable of comminuting any straw residue in the slurry.
    For agriculture, it is an advantage if the tanker can place the manure with a relatively large working width. This limits driving and the resulting driving damage in the field. Driving damage is partly a soil compaction from the weight of the vehicle and partly plants run down by the tractor and the tanker tire assembly. In order to reduce driving damage, it is a common practice among farmers to apply spray tracks in the field. The spray tracks provide certain driving tracks that are reused by fertilizing and spraying growing crops. In addition to driving damage, the spray tracks provide easy access to reduce the risk of over fertilization, limiting overlapping allocation during fertilization. The spray tracks are placed at a certain fixed distance between each other, whereby the field is divided into parcels.
    Fields are often surrounded by shelters and other vegetation. This means that a working width setting which only blocks the outlets of the hoses is not considered usable, since the sections of the side wings will still collide with the shelter when the tanker has to follow the spray tracks laid in the field.
    It is part of the entire work process that the tanker, after being emptied during the fertilizer application, often has to drive off-road and possibly public roads to a stationary tank near the farm to be filled up again.
    DK 2016 70924 A1
    This requires that the sections of the side wings can be folded into a suitable transport position. The main rule is that the wing sections are folded and placed along the sides of the tanker with orientation in the direction of travel. The requirement is that the total transport width and transport length of the tanker including the tool does not exceed the limits set by the authorities.
    For tankers to drive by public road, it is widespread that the authorities require the transport width of the tanker itself to be less than 2.55m. However, it is possible in this context that the carriage wheel mounting gives rise to a transport width of up to 3, Om in cases where the wheel mounting uses low pressure tires. The exception rule has been introduced to reduce the aforementioned driving damage due to soil compaction. Finally, the working tools connected to a tanker can in some cases be accepted with transport widths up to 3.3m. The regulatory requirements provide a space between the tank and permissible transport width and above the tire assembly where a wing section from a tow hose boom can be placed during transport.
    At large working widths, there is a need for the side wings and hose holders to have some distance from the ground so that unevenness in the field does not lead to collision during fertilizer application.
    Here it has become common practice to use hoses of a flexible material and ensure that the hoses each have a certain length to maintain the required safety distance to the ground surface, which in turn prevents collision with the sections of the side wings.
    The practice has also evolved that the hose holders can fold up the hoses from a working position where the hoses outlet points into the ground and to a transport position where the hoses outlet is oriented upwards.
    Folding the hose holders also has the practical advantage that any fertilizer residues in the hoses, distributors and feeds to the implement after application have not been wasted during transport and pollute roads and farms.
    DK 2016 70924 A1
    However, the use of flexible hoses causes the hoses to change shape and bend as they are used. If the hoses are located externally along the sections of the side wings during transport, the deflection will cause the transport width to increase slowly.
    It is desirable to ensure the possibility of placing the implement sections and hose holders in a transport appliance over the tank mount wheel assembly, thereby limiting the overall transport width. It should also allow folded hose outlets to be placed between folded wing sections so that there is no gradual increase in the transport width. It is noted that individual hose holders are mounted on the individual sections and that they have a length corresponding to the length of the associated section.
    It is quite common for towing hoses in the working position to be positioned in the rear of the tanker most often suspended in a main frame in a three-point suspension or the like, which permits interconnection of various implements with the tanker. This location is convenient in situations where fertilizer is to be applied in a field hay, as the tanker can support the corner and ensure full fertilizer coverage.
    By placing the hose boom in the rear end, there is a natural division of the boom into one center section and two side wings, one right and left divided into sections. Although a right and left side wings are not required in principle, the symmetrical placement makes sense to maintain balance in the tanker and does not require unnecessary extra weight.
    Authorities' maximum permissible transport length for a vehicle limits the length of a tractor-driven tanker truck. To ensure that the tractor is able to carry a trolley with a tanker, the length of the tank in the towed vehicle cannot be greater than 10 m. This allows the largest tractor-drawn and self-propelled tankers to establish a working width around 24 m at to fold two sidewalls along the tanker in transport.
    However, the tanker length in the field is not insignificant as the amount of crops driven down with the tractor and tanker wheel mounting increases the longer the tanker is. This results in smaller field sizes and more irregular field shapes
    DK 2016 70924 A1 a desire to choose more compact tankers where the tank length is smaller, for example 8 m.
    It gives rise to the desire to divide the side wings into at least two sections, an inner and again an outer section which can be folded in transport position. It is in principle possible to displace instead of fold, just as it is possible to fold around several axes.
    To reduce driving in the field, you can now see spray track distances from 20, 24, 28, 30 and up to 36 m. To cover the most common working widths at a folding of 20, 24, 30, and 36 m it is necessary again dividing a side wing into several sections most often 3. It is often seen today that one of the sections will have to fold backwards, whereby the transport position will comprise 3 sections in layers and not the desired maximum of 2 sections, the conversion being considered difficult.
    There is a desire to solve the shift work from one working width to another working width automatically, without the need for manual switching, and there is also a desire to ensure that there are no more than two sections in layers during transport.
    The folding of the inner and outer sections is usually carried out by hydraulic cylinders. The hydraulic cylinders make mechanical stops to give the sections their positions in the working and transport positions, respectively.
    In some cases, mechanical stops may also be involved in the sections to limit the forces present at the work post. However, each hydraulic cylinder has no more than two known positions.
    It is also known to allow the entire tow hose boom to rotate about a horizontal axis in the forward direction. This movement must remove unnecessary vertical movement due to unevenness in the tanker tramline and limit the acceleration forces to which the hose boom is exposed from the driveway.
    From EP2959763A1 it is also known to divide the middle section into two frames hinged at the top, while at the same time both frames at the bottom each have their own hydraulic cylinder, which in turn is connected by a common hinge joint. This combination does
    DK 2016 70924 A1 possible to lift both side wings simultaneously. Finally, the entire tow hose can still turn.
    However, none of the above mentioned solutions provide the possibility of lifting and lowering the side wings independently.
    The object of the invention
    The present invention aims to provide a spreading boom of the type mentioned above with a foldable side wing, which is divided into sections which can produce different working widths depending on the chosen layout of spray tracks in the field.
    Furthermore, it is intended to provide a spreading boom which can carry out a transfer from a transport position to a selected working position without the need to completely fold out the sections of the side wings when the spray track distance to a possible fence limits the space.
    Description of the Invention
    This is achieved according to the present invention with a spreading boom of the type mentioned at the outset, characterized in that sensors are arranged between each section and between sections and the main frame, respectively, to determine the mutual position between the sections and between the sections and the main frame respectively. connected to a computer which, on the basis of input from the sensors, generates an output for controlling valves in the hydraulic system for activating relevant actuators.
    According to the invention, a computer control is used which by means of the sensors monitors the folding of the individual sections or hose holders. In this way, it is possible to prevent collision between the hose holdings, the hoses and the sections during the folding and the sections' distance to any shelters can be checked.
    The folding is preferably done by pivoting the hose holders or sections through an angle of 180 degrees.
    DK 2016 70924 A1
    The moment a transfer from a transport position to a selected working position is required, there is not always room to completely unfold the sections, as the spray track distance to a possible fence will limit the space. Since the hose holders must be folded down simultaneously from a transport position to a working position without the hose holders or hoses colliding with parallel hose holders or hoses, it is necessary to know where the sections are located. This is ensured by the sensors.
    According to a further embodiment, the invention is characterized in that the sensors comprise angle sensors which determine the mutual angle between the sections and between the sections and the main frame.
    Preferably, angular sensors are used which enable a simple way of determining the mutual position of the sections.
    According to a further embodiment, the invention is characterized in that the computer is arranged to independently unfold the two side wings.
    It is possible to automate all workflows by folding the sections using the computer control.
    According to a further embodiment, the invention is characterized in that the computer is arranged to independently unfold the sections in each side wing.
    This makes it possible to cover the most common working widths such as 20, 24, 30, and 36 m. And the conversion can be done simply by means of the computer which controls the sections individually.
    According to a further embodiment, the invention is characterized in that each side wing comprises an inner section and one or more outer sections, preferably three outer sections.
    The distance between the driving tracks will be fixed for one farm, but may vary from farm to farm depending on the working width of the implement used.
    DK 2016 70924 A1
    For this reason, it has a value for a machine that serves multiple farms with manure exit, that the implement can have varying working widths and that the conversion from one working width to another working width can be carried out in a simple and quick way.
    By splitting a side wing into several sections, it is possible to establish more working widths.
    A side wing cannot be fully swiveled when it is placed in the transport position, as the outer sections would then collide with a tractor intended to tow the tanker. Therefore, the side wing swings to a first position. Here, an outer section will be perpendicular or at a greater angle than 90 degrees on an inner section. When the outer section is swung to this position, the inner section hose holders with the hoses can be swung past the outer section to a working position. When the hoses are placed in their working position, the spreading boom can be pivoted to a position where the outer section has a beginning oscillation behind the inner section. In the final working situation, the lateral wing is positioned with the outer section (s) having the hoses oriented upwards, superimposed on one or more inner sections which have the hoses oriented downwards in a working position.
    According to a further embodiment, the invention is characterized in that each side wing comprises three sensors. A sensor must be provided between each adjacent section. Thereby the number of sensors will vary with the number of sections.
    These are used to determine the mutual position of the side wing sections as well as the position of the side wing relative to the main frame.
    According to one aspect of the invention, an angle sensor is also provided at both side wings to determine the vertical position and enable a fully automatic folding of the side wing from a given working position to the determined transport position along the sides of the tanker.
    According to a further embodiment, the invention is characterized in that the actuators are hydraulic actuators and that all or some of the actuators comprise a motor, of which
    All or some of the engines are equipped with a hydraulically activated brake that can hold the engine position when no hydraulic pressure is supplied to the engine.
    Alternatively, just some of the actuators may have an engine and others may be hydraulic piston / cylinder devices. Also, in some situations, not every engine is fitted with a brake. Thus, at extreme sections the motor can operate without braking when the joint has a low weight.
    With the help of the sensors, the computer control can control the oil flow from the valves that activate the necessary actuators in the form of hydraulic cylinders. However, hydraulic cylinders will cause a very uneven movement, with sections having to perform a nearly 180 degree turn, and this can give rise to extraordinary loads in hinge joints and sections. This uneven movement can be removed when using hydraulic motors instead of hydraulic cylinders.
    However, hydraulic motors do not have an actual mechanical stop, which is why the use of hydraulic motors will require that the aforementioned angle sensors are not only used to control the unfolding from transport to working position, but also used to hold the working position.
    However, it is recommended in this context that a hydraulic brake be included in the hydraulic motor which, in the event of a loss of movement during the movement or the tractor being abandoned so that the sections cannot move uncontrolled due to leakage over the engines.
    Hydraulic motors do not have an actual mechanical stop, so the use of hydraulic motors will require that the aforementioned angle sensors are not only used to control the folding between transport and working position, but also used to hold the working position. However, it is recommended in this context that a hydraulic brake be provided in the hydraulic motor which, in the event of a movement stop being stopped along the way or leaving the tractor, prevents the sections from moving uncontrolled due to leakage over the engines.
    DK 2016 70924 A1
    The use of hydraulic motors also has the advantage of requiring less space. That space saving will be helpful as you increase the number of distributors used in the hose boom. It is well known that the accuracy of the fertilizer allocation at start-up increases with the number of distributors used.
    According to a further embodiment, the invention is characterized in that each side wing is mounted on the main frame via a lower hinge joint comprising a ball joint and a top hinge joint comprising a long hole guide allowing the side wing to swing in a substantially vertical plane.
    A ball joint is used as the lower hinge joint for both side wings and a long hole guide with associated pins and hydraulic cylinder for holding and moving both side wings in an up and down direction independently of each other. It gives full freedom to adapt to slopes, whether at the bottom or the top of the slope.
    Furthermore, it is possible to produce a suspension of the two side wings by connecting separate accumulators to each of the side cylinders lifting cylinders. This ensures that not only unevennesses that cause tank movements of the tanker are damped, but also unevennesses that require lifting of the tanker. This can reduce the overall acceleration forces in the lateral wing.
    According to a further embodiment, the invention is characterized in that the sensors comprise a height sensor mounted on each side wing connected to the computer, which, on the basis of input from the height sensor, generates an output for controlling valves in the hydraulic system for actuating an associated actuator. the long-hole guide for adjusting the position of the side wing relative to the ground surface.
    Hereby it is also possible with the invention to automate the height adjustment of the side wings by coupling a height adjustment sensor for both side wings.
    This allows the hose outlet of the implement to be in close contact with the ground surface of the fields, regardless of the height variations.
    DK 2016 70924 A1 π
    According to a further embodiment, the invention is characterized in that the sensors comprise a height sensor mounted on the main frame and connected to the computer, which, on the basis of input from the height sensor, generates an output for controlling valves in the hydraulic system for actuating an actuator which is attached to the main frame for adjusting its position relative to the ground surface.
    This allows the hose outlet of the implement to be in close contact with the ground surface of the fields, regardless of the height variations.
    According to a further embodiment, the invention is characterized in that the sections or hose holdings can swing through substantially 180 degrees from a working position where the outlet of the delivery hoses is open and oriented downwards and an upwardly directed position where the outlet is closed.
    The folding of the hoses to the transport position allows the sections of the side wings and the hose holders to be placed over the tank mount wheels, thereby using the free space along the tank wagon to reduce the overall transport width of the implement.

    Detailed description of the invention
    Incidentally, a spreading boom 1 is shown in the form of a tow hose boom. The spreading boom comprises a main frame 2 and two side wings 3 mounted thereon. Each of the side wings 3 comprises an inner section 4 and a first, second and third outer sections 5-7. A central section 35 of the spreading boom is mounted on the main frame 2.
    Each of the sections is provided with application s hoses 8, each having an outlet opening 9 at a downwardly directed part of the hose, which is intended to be placed in close contact with the soil surface 21 (see Figure 3) when advancing during application of fertilizer. The main frame 2 of the spreading boom 1 is mounted on a tank wagon 10 via a height adjustable bracket 11 at the rear end of the tank wagon as seen in the forward direction 12 of the tank wagon.
    Figure 1 shows the spreading boom in a working position where all the sections of the side wing are pivoted to a boom position which is substantially perpendicular to the direction of transport 12. The side wings can be pivoted to a transport position shown in Figures 4 and 5, where the side wings are arranged in planes. 13, which are parallel to the direction of travel 12.
    Each of the side wings 3 is connected to the main frame 2 via a lower hinge joint 14 comprising a ball joint and an upper hinge joint 15 which includes a long hole guide.
    DK 2016 70924 A1
    Thus, it is possible that each of the side wings 3 can swing in a substantially vertical plane, regardless of whether they are in the working position.
    Figure 2 shows a partially enlarged view of the spreader boom shown in Figure 1. Hinge joints are provided between each of sections 4, 5, 6 and 7. Hydraulic actuators are provided between each of sections 4, 5, 6 and 7 in the form of a motor 19 provided with a hydraulically actuated brake. Thus, it is possible to maintain the position of the engine when no hydraulic pressure is supplied to the engine 19. The motors are supplied with hydraulic oil from the tractor's hydraulic system (not shown). The hydraulic system is provided with valves (not shown) which enable individual activation of each of the motors 19 for individually pivoting the boom sections.
    Each of the side wings 3 is similarly provided with a hydraulic motor 19 for pivoting the side wings 3 with respect to the main frame 2.
    In Figure 2 it is seen that the hoses 8 are mounted in a hose holder 20. The hose holder 20 is mounted via hinge joint 21 for pivoting between the downward orientation of the outlet openings 9 shown in FIG. To the upwardly oriented orientation shown in figures 4 and 5 with the outlet openings oriented. upwards.
    It is noted that the hose holders on each section can be individually pivoted between 180 ° from the working position, where the outlet opening 9 is oriented downwards and an upward position where the outlet from the hoses 8 is closed.
    Figure 3 illustrates a situation where all sections of the spreader boom are fully unfolded and located with the hoses 8's outlet opening 9 in the immediate vicinity of the ground surface 21.
    Figures 4 and 5 illustrate, as previously mentioned, the side wings 3 in a transport position in such a way that the inner section 4 is folded forward, while the three outer sections 5, 6 and 7 are folded backwards in a position superimposed on the inner section 4.
    The main frame 2 is raised via the height-adjustable bracket 11, so that each of the side wings 3 is placed in a position close to the tanker tank 22 in a position above the wheels of the tanker 23. There is a very small transport width. Furthermore, it is seen by one
    DK 2016 70924 A1 enlarged detail image of Figure 5 that the hose holders 20 are positioned so that the hoses 8 from the superimposed sections 4 and 5, 6 and 7 are offset from each other. Thus, the hoses 8 will be positioned side by side, which helps to reduce the transport width. Furthermore, it is seen that the hoses are located in the spaces between the superimposed sections 4 and 5, 6, 7, respectively. Hereby the hoses will have a fixed upward orientation and will not tend to unfold, which would increase the transport width.
    Figure 6 illustrates a situation in which the one wing of the spreading boom is fully unfolded to a working position, while the other side wing 3 of the spreading boom is placed in a transport position. With such a situation, it is possible to apply a liquid fertilizer alone at one side of the tanker and behind the tanker via the central section 35.
    Figure 7 illustrates the situation shown in Figure 6 from above in the picture on the far left. Figure 7 illustrates the situation of a side wing 3 in working position with all sections fully extended.
    Situation B illustrates the side wing 3 in a working position with section 7 overlaid with the other sections.
    Situation C illustrates a working position for the side wing 3, where sections 6 and 7 overlay sections 4 and 5.
    Situation D illustrates a working situation from the side wing 3, where the three outer sections 5, 6, 7 are superimposed on the inner section 4.
    As can be seen from the above, it is possible to individually position the sections so as to adjust the spreading boom's total working width. This is done without manual intervention. This is done by means of a computer (see Figure 10), operated by the tractor driver, which controls the actuators for the individual positioning of the spreading boom sections.
    Figure 8 illustrates the tank truck 10 having its forward direction 12 along a driving track 25. An abutment boundary 26 is illustrated.
    DK 2016 70924 A1
    Only the left side wing 3 is illustrated in various positions during oscillation.
    A side wing cannot be fully swiveled when placed in transport position, as the outer sections 5, 6, 7 would then collide with a tractor (not shown) intended to tow the tanker 10. Therefore, the side wing swings to position A. Here, the outer sections 4, 5, 6 will be located perpendicular to the inner section 4. When the outer sections are pivoted to this position, the hose holder with the hoses 8 can be pivoted past the outer section to a working position shown in Figures 1 and 2. When the hoses are placed in their working position, the boom can be swung to position B, where the outer sections have a beginning oscillation behind the inner section 4. In situation C, the final working situation is shown, where the side wing is located with sections 5, 6, 7 superimposed section 4 which has the hoses 8 oriented downward.
    By analogy, it will be possible to swing sections 4 and 6 together with section 4. It merely needs to be ensured that the sections are mutually positioned so that the hose holders can freely swing the hoses, the transport position and the working position.
    The mutual positioning of the sections is ensured by sensors provided at 27 in the figures. The sensors are provided between each of the sections as well as between the sections and the main frame. The sensors 27 are angular sensors which determine the mutual angle between each of the sections and the main frame and which are connected to the computer 24. Thus, the computer 24 can control valves for actuating the hydraulic motors 29 in a manner so that proper in and out of the the individual sections.
    Swing in and out can be done via predetermined programs in the computer 24 or by the operators making optional settings of the individual sections.
    The position of the sensors 27 is illustrated in Figures 1 and 2.
    In Figure 8 an angle Θ is indicated, which is the angle between a plane parallel to the direction of travel of the tanker and a given angle for the position of the innermost
    DK 2016 70924 A1 section in relation to this plan. Furthermore, at 30, an angle ivet is indicated, which is the angle between the inner section 4 and the outer sections 5, 6, 7. These angles are included in figure 10. Here the different commands are shown for swinging and swinging and illustrating different work - and transport positions as well as various intermediate positions.
    Figure 9 illustrates the angle sensor 27 located between the main frame 2 and the side wing 3 for determining an angle α indicated by 31. The angle a is the angle of the side wing 3 in a position 32 relative to a horizontal plane 33. This angle can be adjusted using a height sensor.
    Figures 1 and 2 and 9 further illustrate a height sensor 28 which is located at the outer end of each side wing 3. The height sensor 28 is also connected to the computer 24 to ensure an angular position so that the position of the side wings with respect to the ground surface 21 is ensured. on uneven terrain.
    Figure 9 also indicates a height sensor 34 mounted on the main frame 2. The sensor 34 is used to determine the position of the main frame relative to the ground surface 21. This also determines the position of the spreading boom 1 in relation to the ground surface.
    Figure 10 illustrates, as previously mentioned, the computer 24. In this figure no wires are shown which connect the computer with sensors, nor are wires shown connecting the computer with valves for controlling the various actuators.
    With arrows between the various figures, it is illustrated how the spreading boom can be shifted between different working positions based on control signals generated by the computer as a result of input from the sensor. The computer will control folding and unfolding in accordance with predetermined algorithms which ensure that the different sections and / or hoses of the spreading boom do not collide with each other during continuous unfolding and at the same time ensure that the spreading boom does not collide with the tanker or the tractor pulling the tanker.

    Folding and unfolding can be done individually for each side wing, as well as individually for each of the spread boom sections.
