    Tillage Tool Field of the Invention
    The present invention relates to a tillage tool comprising a tool frame having several parallel carrying vanes extending across a working direction and each provided with parallel tillage tools, said tool frame being divided into at least two tool sections which are pivotable connected to be able to pivot between a horizontal working position and a vertical transport position.
    BACKGROUND OF THE INVENTION
    Tillage tools may be provided with different types of tillage tools, such as earthen teeth and dishes.
    In the following, the invention will primarily be described with reference to spring tooth harrows, the invention being developed in connection with such implements.
    Agricultural land is prepared for plant production by, among other things, plowing, harrowing and fertilizing the soil before the upcoming crop is deposited in the soil during sowing.
    To ensure efficient plant production, it is common practice to perform certain workflows in combination. It is common for seed preparation and sowing to be carried out simultaneously, just as fertilization and seed preparation or fertilization and mulching are also combined.
    In particular, manure with livestock manure has evolved in the direction of precipitating manure with the help of spring teeth. This places the slurry in the soil, thereby reducing evaporation, dilution and odor nuisance.
    Slurry trucks are typically used today with slurry traps due to the legislation. A slurry trap is a combination of a harrow and a snake trap. The harrow first cuts into the ground and the snake trap places the slurry, while a subsequent drum again covers the laid slurry.
    The combination of slurry traps and harrow is a relatively new technique, which in recent years has become a legal requirement in some countries to reduce the environmental impact of slurry application.
    It is a known technique to cultivate black soil using tillage tools with spring teeth. Each tooth cuts into the soil, lifting and turning the overlying soil up over leftover plant residues.
    The individual spring teeth are usually mounted with a certain distance between each spring tooth in a row. By rearranging several rows of spring teeth, most often two or three rows, one after the other in sections where the teeth in each row are offset from each other, the total tillage increases while giving each tooth the best opportunities to cover plant residues.
    By placing spring teeth in several rows arranged parallel to one another in the working direction of the implement, the distance between the spring teeth is reduced and a closer machining of the ground is achieved.
    Tillage tools are also known with soil tillage tools other than spring teeth. Thus, tillage tools are also known in the form of disc harrows, where several rows of discs are used for tillage.
    It is also known in the art to use two-section or three-section tillage tools. Typically, three sections are used where two side sections can be folded up from a horizontal working position to a vertical transport position over a center section.
    Spring tooth harrows are now manufactured either as lift-mounted implements for a tractor or towed implements depending on a tractor. The working width of lift-mounted harrows is often limited partly due to the weight of the harrows and partly due to traffic legislation.
    Most lift-mounted solutions are based on three sections, and a smaller center section is used in the center of the implement, to which a right and left side section is hinged, which can be folded up over the center section during transport.
    Harrows with larger working widths are therefore typically manufactured as towed implements, where a special transport unit allows the sections not to be placed in succession but behind a front section during transport.
    In combination tools where the harrow is used in combination with a slurry spreader, the harrow will most often be hung on the slurry trolley. In this case, the slurry trucks are equipped with a three-point suspension known from tractors.
    The general traffic rules stipulate maximum widths, heights and lengths for tools to be transported by public road.
    It is common for the maximum permissible transport width to be 3 m and the permissible transport height to be 4 m. In Denmark, according to retail regulations for vehicles, the total length of a vehicle (tractor + trailer) must not exceed 18.5 m. the total length of the trailer alone shall not exceed 12 m, the width shall not exceed 3 m, and the height shall not exceed 4 m.
    Traffic legislation means that the maximum working width of a tillage tool, such as a single section spring tooth harrow, is often just under 3 m.
    The spring height of the spring tooth harrow itself will limit how many sections can be established in a row and folded over a center section during transport.
    By folding up two sections during transport and back into working position, it is possible with two sections to produce up to 2x3.5 = 7 m working width. The back ground for not creating 2x4 = 8 m comes from the fact that transport to and from the field requires up to 0.5 m clearance between the ground and the lower implement part so that the implement does not grab the ground.
    The desire to increase the working width of lift-mounted tillage tools has not been of interest to ordinary harrows, since the towed technique provided better opportunities.
    The use of three-point mounted harrows together with a slurry trailer has increased the interest in seeking larger working widths for lift-mounted tools.
    It is also known for harrow tools used in combination with slurry trucks that the two side harrow sections that are folded up during transport are fed to a fold-out side wing with single spring teeth mounted. These side wings, when folded in, can reduce the height during transport.
    This movable side wing is added to the outside of existing sections and folded out during work, thereby providing the opportunity to increase the working width with yet another addition corresponding to the width of the folded side wing.
    There has been a desire for several years to increase the working width of slurry implements, including the width of the harrows used in combination with a slurry trolley. But there is also a desire for an opportunity to secure ground clearance during transport.
    The object of the invention
    It is the object of the present invention to provide a tool of the type mentioned initially where this wish is fulfilled and where it is also possible to establish a tool which is technically simple in its construction.
    Description of the Invention
    This is achieved according to the present invention with a tool of the type mentioned initially, which is characterized in that on each side of the two implement sections there is arranged a side wing which supports tillage tools and which can be pivoted or displaced between an inner transport position and an outer working position to increase the working width of the implement.
    The new thing is to place two pivotable or sliding side wings for each implement section. These extra movable side wings will partly ensure the ground clearance during transport and partly provide wide working width. Thus, the movable side wings facing each other will be raised above the bottom bearing as they move toward the inner transport position after the two implement sections are pivoted to their vertical transport position.
    The two implement sections are pivotally suspended in a frame so that when pivoted to the working position, they are spaced apart. Only after movement of the side wings facing each other will the two tool sections be closely juxtaposed so that tools are spaced across the entire width of the tool with a uniform desired spacing.
    The principle of the invention has been that known implement technique is used which is based on the use of only two implement sections instead of three. This results in a construction which is simpler and where it has also been found that it is actually possible to achieve a large working width and at the same time the ground clearance. By using side wing on both sides of each implement section, it is possible to add large working width and clearance height by adding an additional folding or shear mechanism in each implement section.
    According to the invention, various mechanisms can be used to establish a movement of the two side wings.
    Surprisingly, it has proved possible to limit the number of implement sections to two instead of three sections and at the same time increase the working width. Reducing to two sections will, all else being equal, reduce the complexity of the implement.
    Thus, hydraulic or electric actuators can be used. The mechanisms which establish the movement of the side wings will typically be associated with a central support frame used at the same time to support the implement sections of the implement. The tool sections will then be mounted for pivoting around a central support frame.
    If the tooth spacing is well over 0.75 m, a total working width of size 2x (3.5 + 0.75 + 0.75) = 10 m will appear.
    It is also part of the invention that ground clearance of the frame members in each implement section is performed with a mechanical lock when positioned in the working position. This blockage must ensure a more robust overall frame construction in the working position.
    However, for combination equipment in the form of slurry trailer and harrow for folding, it is also possible to use the towed technology. Thus, the tillage tool may be hung on a towed frame connected to a towbar at the back of the slurry.
    Furthermore, the tiller may be mounted in a three-point suspension but may have a frame on which support wheels are mounted. Thus, it can be said that the tillage tool acts as '' semi-towed '' tool.
    Thus, as an alternative to being lift mounted on a slurry, tillage equipment can also be towed, semi-towed or lifted directly on a tractor.
    According to a further embodiment, the invention is characterized in that the tillage tools are spring teeth. The spring teeth will generally be used for tillage in connection with slurry harvesting. The spring teeth will therefore be placed on a harrow assembly mounted on the back of a slurry trailer. In slurry application, it is especially important to have as compact construction as possible on a lift-mounted tillage tool.
    According to a further embodiment, the invention is characterized in that the tillage tools are plates. Plates can be used either alone or in conjunction with other tillage tools, such as compactors.
    According to a further embodiment, the invention is characterized in that the implement is a lift-mounted implement. As mentioned earlier, the advantages of the compact construction are particularly advantageous for lift-mounted implements, in that the movement of the side wings to the transport section gives both a reduced upper height and a high clearance when switching the implement to the transport position.
    According to a further embodiment, the invention is characterized in that the carrier vanes are formed by telescopic tubes which allow for displacement of the side wings. By using telescopic tubes a rigid construction is obtained. At the same time, the telescopic tubes can advantageously be formed by carrier wings with substantially the same construction as traditional harrows.
    According to a further embodiment, the invention is characterized in that the displacement of the side wings between the inner transport position and the outer working position corresponds to the distance between parallel soil tillage tools in the associated implement section. This results in the optimal insertion of the side wings. It is possible to have multi-level telescopic wing so that not only one telescopic insert but two or more telescopes allow for a greater working width.
    According to a further embodiment, the invention is characterized in that the side wings are hinged about a vertical shaft at the front end of an associated implement section, so that the rear tillage tool is moved from the transport position to the working position a distance corresponding to the distance between parallel soil tillage tools. tool section. As an alternative to displacement, the movement of the side wings can be effected by a pivot about a vertical shaft. The vertical shaft will preferably be located at the front end of the implement section, but may alternatively be located at the rear end. The most important aspect here is that the oscillation of the side wings occurs at such an angle that the distance between the tooling tools is increased by a distance corresponding to the distance between parallel earthworking tools. Thus, an additional machining width is obtained on each side corresponding to the distance between two machining tools.
    According to a further embodiment, the invention is characterized in that the two implement sections are mounted on a support frame supporting an actuator connected to the side wings for establishing the movement between the inner transport position and the outer working position. By using a support frame, an advantage is obtained in that the support frame can be provided with the mounting points for the lift attachment of the implement. Thus, the support frame can easily be provided with hydraulics from the tractor and an actuator can be used as an actuator.
    Alternatively, electric actuator can be used. A mechanical actuator can also be used to establish the movement of the side wings.
    According to a further embodiment, the invention is characterized in that the two implement sections are pivotally suspended in the support frame, so that, when pivoted to the working position, they are spaced apart and that the two implement sections will only be after movement of the side wings facing each other. closely juxtaposed, so that over the entire width of the tool are tools with a uniform desired spacing.
    With just two tool sections, a simple construction is achieved compared to the more traditional three-piece tools. The two implement sections will be located at a pivot point with a spacing in the support frame. The spacing between the pivot points located below the support frame will be '' filled '' with tools when the side wings facing each other are extended to the working position. If the inner side wings facing each other were not displaceable, a pivot to the transport position would cause these lateral wings to swing too close to the ground after pivoting the implement section to a vertical transport position. Thus, with the sideways offset facing each other, a uniform tillage is achieved over the entire width of the implement.
    According to a further embodiment, the invention is characterized in that it is mounted on a slurry trolley. As mentioned above, the need for a soil tillage implement according to the invention will be particularly useful as a lift mounted implement suspended on the back of a slurry tank.

    Detailed description of the invention
    FIG. 1 shows a tillage tool 1 according to the invention. The tillage tool is mounted in a three-point suspension 3 at the back of a slurry 4. A hose arrangement 5 contains a number of single hoses 6. The single hoses 6 are located at the back of tillage tools 7 in the form of harrow teeth 7, so that the slurry can be placed in the gutter which is formed by the harrow tooth 7.
    Harrow tines 7 are provided in three rows 8, the harrow tines 7 being mounted on carrier blades 9 which extend across a working direction 10 of the tillage tool 1. The tool 1 has a tool frame which is divided into two tool sections which will be explained in more detail in the following. In the illustrated situation, the tool sections are positioned in a horizontal working position with an extension in extension of each other across the working direction 10.
    FIG. Figure 2 shows principle sketches for the construction of implement sections 11 which form part of the tillage tool. In FIG. 2, the implement sections are shown without the tillage tools. It will be seen that each implement section 11 comprises three parallel support vanes 9 for the tillage tools. At each side of a section a side wing 12.1 is provided. The upper figure shows that the two side wings 12 are slidable. The lower figure shows that the two side wings 12 are pivotable. The middle figure shows a combination with a extendable and a pivotal side wing 12.
    In the principle sketches shown, all the side wings 12 are shown in an outer working position, where the side wings are offset to an outer position. When the implement is to be transported, the side wings will be displaced or pivoted towards an internal transport position, respectively, thereby reducing the extent of the implement during transport.
    The sliding side wings are provided by telescopic carrier wings, which will be explained later.
    The pivotal side wing 12 is mounted on a vertical shaft 18 at the front end of an associated fixed implement section 11. Thus, the rear tillage located on a frame portion 19 can be moved at a distance corresponding to the distance between parallel tillage tools in a associated with fixed implement section.
    FIG. 3 shows a working tool in the form of a harrow having a number of harrow teeth 7. The harrow has the working direction 10, as indicated by the arrow to the right in the figure.
    In this figure, the two side wings 12 are extended. Hereby, equal distance A between the harrow teeth on each carrier 9 will occur. In this situation, the distance B between harrow teeth located on subsequent carrier 9 will also be identical.
    In this situation, the harrow is thus in its working position.
    FIG. 4 shows the one in FIG. 3 of the implement section 11. In this figure, the two side wings 12 are displaced towards an inner transport position. Hereby it is seen that the distance between the harrow teeth in the lateral wings and an outer harrow tooth on the fixed section 9 of the carrier section is reduced to the distance C.
    The jointing takes place in that the carrier vanes 9 are formed by an outer and inner telescopic tube 13, 14. In the jointing of the telescopic tubes, the side wings 12 can be displaced at a distance corresponding to the distance A between parallel harrow teeth 7 in a tool section 11. the total width of the implement section reduced. This is important when the displayed implement section for transport will be pivoted to a vertical transport position. Thus, the height of the implement in the transport position will be reduced due to the insertion of one side wing, and at the same time the clearance under the implement will be increased due to the insertion of the other side wing. This is more clearly illustrated in FIG. 5 and 6.
    FIG. 5 and 6 illustrate the two implement sections 11 with the side wings in a deferred position and a staggered position, respectively. The two implement sections 11 are mounted in a common support frame 15. The implement sections 11 are pivotally mounted around pivot pin 16. Hereby the implement can be pivoted from the one shown in FIG. 5 and 6 show a vertical transport position for a horizontal working position. In the vertical working position, it is clearly seen how by pushing the side wings 12 into their inner transport position a reduction in the transport height and the clearance height will be obtained, which will be provided below the lower part 17 of the support frame 15, which is arranged for mounting to a traditional three-point suspension.
    FIG. 7 shows a partial view of a tool section 11. Here it is more clearly seen how the inner telescopic tubes 14 are made in the form of square tubes which are inserted into the inner telescopic tubes 13. The inner telescopic tubes 13 form the fixed part of the tool section 11 .
    In FIG. 7, there is also seen a post harrow 20 mounted on the implement section 19. The back harrow 20 is provided with tillage tools 21 which serve to cover the grooves formed by the harrow teeth 7.
    At the back of the harrow teeth is seen a bracket 22, which is intended for mounting slurry 6s.
    The post harrow 20 is also made with telescopic tubes which can be pushed together at a distance corresponding to the intersection of the side wings 12. Thus, the post harrow can also be pushed together at each end corresponding to the interlocking of the two side wings 12, which are attached to a tool section 11.
    FIG. 8 illustrates a further embodiment of a harrow section 11. Here, it is seen how the side sections 12 are provided with a bracket plate 23. On the bracket plate 23 is mounted a hollow telescopic tube 24, which in the form shown comprises an inner and an outer tube. IN
    In the telescopic tube 24, an actuator (not shown) is mounted, which can be formed, for example, by an electric or hydraulic cylinder, which allows the two pipes to move mutually. Alternatively, the actuator may be mounted other than inside the pipe. Thus, the actuator may be located outside of the telescopic tube 24.
    In FIG. 9 shows an actuator in the form of a hydraulic cylinder 25 which is used for the insertion and extension of the side wings 12. The hydraulic cylinder 25 is connected at one end to the support frame 15 and at the other end to the side wing 12 of the implement section II and thus enables the insertion and extension of the side wings 12.
    In FIG. 9 is a top view of a tool according to the invention with a support frame 15 provided with a three-point suspension in the form of two lower connections 26 and an upper connection point 27 for connection with a normal lifting suspension. The two frame sections 11 are suspended in the support section 15 for a pivot between the horizontal working position shown, the side wings being extended in both implement sections 11 and a vertical transport position, as shown in FIG. 6th
    In FIG. 9 it can be seen that the support frame 15 can also be used to support other types of tillage tools. Thus, the tillage implement of the present invention can be used in conjunction with support frames which may be included in a general support system. The middle figure shows a working tool with harrow teeth. The bottom image shows a working tool in the form of two rows of plates 28 and a compact roller 29.
    In the embodiment shown, the other tools 1 are not shown with movable side wings 12 on the tool sections 11. However, it will be possible for the tillage tools in a tool according to the invention to be made of plates 28.
