    “MODULAR AGRICULTURAL CUTTING UNIT FOR A WORKING MACHINE”
    FIELD OF THE INVENTION [001] The present invention relates to an agricultural cutting unit having a horizontally arranged axis driven in rotation, with a plurality of cutting elements arranged therein.
    [002] The cutting unit is mounted on a working machine or forms the same, and is used in particular to cut and / or shred grass, straw, grain, wheat, corn, rapeseed, sunflowers, beans, other stems and other plants and plant parts. The cutting unit is aligned with its approximately horizontal cutting plane.
    [003] The cutting unit can in particular be a flail cutter for a combine harvester.
    State of the art [004] An agricultural cutting unit for a mobile working machine is known from the brochure “Spearhead.eu; Spearhead - Stoppelmanagement: Die Erntereste im Griff ”(Stubble Management: The harvest residue under control). The mobile working machine is a tractor on which the cutting unit is mounted. The cutting unit is designed as a flail cutting unit with a horizontally arranged axis driven in rotation, and a plurality of flails arranged on the axis to cut the crop material, particularly crop residues. There can also be a plurality of cutting units mounted on the working machine, with their axes and the individual cutting widths of the cutting units overlapping in order to obtain an overall cutting width. For this, some of the cutting units are arranged, for example, in front of the tractor's front wheels and others behind the tractor's rear wheels.
    [005] Furthermore, it is generally known in the state of the art to provide
    Petition 870190051815, dated 06/03/2019, p. 14/29
    2/13 a combine harvester with several cutting units to cut the crop residue adjacent to the header (for harvesting), which defines the working width of the combine harvester. Here, one of the cutting units is arranged more or less directly in the direction of travel behind the main header, while two other cutting units are fixed behind the rear wheels at the end of the combine harvester and thus, the axes of the cutting units and the cutting widths of the cutting units overlap to form the overall cutting width.
    Purpose of the invention [006] The purpose of the invention is to provide an agricultural cutting unit for a working machine, with which cutting widths different from the cutting unit can be created in a simple and variable way.
    Solution [007] The purpose of the invention is achieved by the characteristics of the independent patent claim. Other preferred embodiments of the invention are mentioned in the dependent patent claims.
    Summary of the invention [008] The invention relates to a modular agricultural cutting unit for a working machine. The cutting unit has a plurality of cutting modules, each having a horizontally disposable axis that can be rotated and a plurality of cutting elements arranged on the appropriate axis for cutting crop material, in which the axes of the cutting modules are not arranged to overlap in the cutting width of the cutting unit.
    [009] The invention also relates to a working machine, in particular a combine harvester or other actionable harvesting device, comprising the modular cutting unit as described above.
    [010] The invention also relates to a modular flail cutting unit for a combine harvester with a support frame and a
    Petition 870190051815, dated 06/03/2019, p. 15/29
    3/13 plurality of flail modules each having a horizontally arranged axis driven in rotation, and a plurality of flails mounted on the appropriate axis, to cut culture material. The flail modules are designed as separate and individually controllable units and to form different cutting widths from the flail cutting unit by combining different numbers of flange modules of the same and / or different widths, directly or indirectly in the support frame and connected together by couplings. The flail modules extend the full working width of the combine harvester.
    Definitions [011] In this order, an agricultural cutting unit is considered to be a cutting unit for cutting, mowing, slicing, chopping, covering with vegetable materials, etc. of culture material in the agriculture and forestry sector, in the municipal sector for the maintenance of green, public spaces, and for the care of other planted areas.
    [012] In this order, a work machine is understood to be a self-propelled work machine, a towed work machine, a combine harvester, a reaper machine, a combine harvester or a tractor having, in each case, a unit of agricultural cut as defined above.
    [013] The working machine has a working width. The working width is understood to be the effective area of action of the working machine perpendicular to its direction of travel. If the working machine is a combine, the working width also corresponds to the cutting width of the cutting unit. If the working machine on the other hand is a combine harvester, the working width of the combine combines the effective cutting width of the header (main cutting unit), while the cutting width of the secondary cutting unit for cutting crop residues it is mentioned not as the working width, but instead as the cutting width. A modular cutting unit is
    Petition 870190051815, dated 06/03/2019, p. 16/29
    4/13 considered in this order as a cutting unit that has several separate modules, the modular cutting unit being created by its direct assembly with each other. In other words, a modular cutting unit is not considered to be the separate cutting units of a working machine, which are mounted at different points on the working machine (mostly in an overlapping arrangement) to produce a width of general cut.
    [014] The cutting unit's cutting area is the area where the cutting unit cuts the culture material. The cutting width of the modular cutting unit is considered to be the width of its cutting area perpendicular to the direction of travel of the working machine.
    Additional description of the invention [015] The new agricultural cutting unit comprises a plurality of cutting modules that are assembled together to form the cutting unit, and thus define the cutting width of the cutting unit, without any overlap in the cutting width. cutting unit. By using modules, each with a separate axis, it is possible to produce different cutting widths from the cutting unit to create a modular system. The cutting modules can therefore be standard units, independent of the overall cutting width of the cutting unit, which can therefore be produced in larger quantities and at a lower cost. From cutting modules with an average width of, for example, 80 cm and / or 120 cm, very large variable cutting widths of the cutting unit can be created including very large widths, for example, 3 m.
    [016] Another advantage over the prior art is that the mounting space required for arranging the cutting unit perpendicular to the width of the cutting unit is reduced. This is because the comparatively short axes of the modules may have a lower bending stiffness and therefore a smaller diameter than would be the case with a continuous axis. Since the shaft diameter, due to the arrangement
    Petition 870190051815, dated 06/03/2019, p. 17/29
    5/13 of the cutting elements in it, broadly defines the installation space of the cutting unit perpendicular to its width, this results in options for mounting the cutting unit that did not exist in the state of the art.
    [017] In this way, it is for the first time possible to arrange the cutting modules with their cutting elements in such a way that the cutting area of the entire cutting unit is, in relation to the direction of travel of the machine, in front of the front wheels . Particularly when the cutting modules of the cutting unit extend over the entire working width of the working machine, this has the advantage that the culture material is not driven over and pressed down by the working machine wheels before be cut. This generates consistently good cutting results over the entire cutting width of the working machine. Furthermore, it is ensured that the cutting results do not depend on the steering position of the working machine, that is, it is not important whether the working machine is moving in a straight line or in a curve.
    [018] The cutting modules are therefore preferably arranged so that their axes can be driven around a common axis of rotation. The geometric axis of rotation is considered to be the geometric axis. The shafts of the cutting modules can individually have their own drive or drives totally or partially separated.
    [019] The cutting modules are preferably formed as separate and individually controlled units for the construction of cutting widths different from the cutting unit by combining different numbers of cutting modules of equal and / or different widths. Even when using only one cutting module width, a wide range of different general widths is created by the arrangement as desired of n cutting modules. By using cutting modules of different widths - for example, cutting modules with 2, 3, 4 or more different widths, there is still a much higher variability, so that the cutting unit can be
    Petition 870190051815, dated 06/03/2019, p. 18/29
    6/13 adapted to virtually any working width of the working machine.
    [020] The cutting modules can be arranged directly or indirectly in a support frame. The support frame is longer than the cutting modules and accommodates several cutting modules. The support frame may be a part or consist of two or more interconnected sections. Advantageously, the support frame is therefore exclusively determined for the cut width of the defined cutting unit to be created. In order to obtain the desired compactness of the cutting unit, it is therefore preferable that the cutting modules are relatively small in size and have a shaft with a relatively small diameter and that the support frame effectively supports the forces and moments and provides the rigidity of bending required.
    [021] The cutting modules can be directly or indirectly attached to the support frame without drilling by fixation. The arrangement without perforation means that the modules can be easily and quickly mounted on the support frame, which provides significant advantages both during initial installation and subsequent maintenance and service of the cutting unit.
    [022] A plurality of connection plates can be attached by fixing and without perforation to the support frame and the cutting modules can be fixed to the connection plates. This further simplifies the assembly and disassembly of the modular cutting unit.
    [023] Two adjacent cutting modules can be connected by means of a coupling, in which the coupling has a spring element that is designed to absorb relative movement forces from the axes of the interconnected cutting modules. This ensures, on the one hand, that the torque required to drive the axes of rotation is efficiently transmitted by one axis through coupling to the next axis, and on the other hand, that no undesirable forces of relative movements of the axes are transmitted.
    Petition 870190051815, dated 06/03/2019, p. 19/29
    7/13 [024] The cutting unit is preferably a flail cutter, where the cutting modules are then designed as flail modules and the cutting elements as flails. In particular, crop residues can be effectively cut, crushed and covered with plant materials using a flail cutter.
    [025] The working machine can in particular be a combine harvester. The new agricultural cutting unit is then preferably used as a secondary cutting unit. The combine harvester, as known, has a main cutting unit, with which the crop, for example, wheat, is cut. The modular cutting unit is then mounted in particular on the rear of the so-called “collector” of the combine harvester. The combine harvester can be specially designed so that its main cutting unit is situated higher than in the state of the art - that is, at a greater horizontal distance from the ground. This reduces the amount of stems pulled into the combine. The new modular cutting unit is then used to cut the remaining relatively long stubble of the earth and to chop it. The modular design and reduced space requirements mean that the cutting unit can now be arranged, in the direction of travel, behind the main cutting unit and also in front of the combine harvester's front wheels.
    [026] Advantageous further developments of the invention are disclosed in the claims, description and drawings. The advantages of features and combinations of various features mentioned in the introduction to the description are by way of example only, and can come into effect alternatively or cumulatively without the benefits having to be obtained by embodiments of the invention. Other features are shown in the drawings - in particular the geometries represented and the relative dimensions of various components to each other and their relative arrangement and functional connection. The combination of characteristics of different modalities of the invention or
    Petition 870190051815, dated 06/03/2019, p. 20/29
    8/13 of different claim characteristics is also possible by means of a departure from the chosen references of the patent claims and is thus suggested. This also applies to those features that are illustrated in separate drawings or are mentioned in their description. These features can also be combined with features of different patent claims. Similarly, features listed in the patent claims can be omitted for additional embodiments of the invention.
    [027] The characteristics mentioned in the claims and specification should be understood, in terms of their number, as exactly that number or a number greater than the number being present, without the need for the explicit use of the words "at least". For example, when an axis is mentioned, it must be understood as precisely one axis, or two axes or several axes are present. If, however, an exact number of a characteristic is being mentioned, the adjective "only" is inserted before the appropriate characteristic.

    Detailed description [040] Figures 1 and 2 show the front part of a working machine 1. In this case, the working machine 1 is represented as a combine harvester 2. However, it could also be a different working machine 1 Only the front part of the working machine 1 is shown, since the rest of the working machine 1 is of no importance to the present invention.
    [041] Working machine 1 is mobile and therefore has several wheels, of which only the front wheels 3 are shown in figures 1 and 2. To perform its work, working machine 1 moves in the direction of travel 4 to the along the ground 5.
    [042] Combine harvester 2 has a main cutting unit 6, which
    Petition 870190051815, dated 06/03/2019, p. 22/29
    10/13 serves the effective threshing process. The main cutting unit 6 defines the working width 7 of the working machine 1 perpendicular to the direction of travel 4. The main cutting unit 6 is not the purpose of the present application and is therefore not described in detail below.
    [043] In addition to the main cutting unit 6, the working machine 1 has a modular cutting unit 8. The modular cutting unit 8 is used to cut the crop stubble left behind in soil 5 by the cutting unit 6, and has a cutting width 9 that approximately corresponds, in the combine harvester 2 shown here, to its working width 7. In other words, in the process used in the combine harvester 2, in the direction of travel 4, the culture material is first cut by the main cutting unit 6 at a greater distance from the soil 5. Next, all remaining stubble is cut by the modular cutting unit 8 closest to the soil 5 and cut upwards.
    [044] The cutting unit 8 is supported by rollers 10 on the ground 5, in particular it is guided by them during the movement of the working machine 1. The rollers 10 have a cage design and in particular consist of metal. The rollers 10 provide good guidance for the modular cutter 8 even in difficult soil conditions eg rocks, holes, ramps, etc.
    [045] Cutting unit 8 extends over the entire working width 7 of working machine 1. Therefore, no additional cutting units are required to cover the entire working width 7 of working machine 1 over several cutting widths. overlapping of several cutting units, as known from the state of the art. Consequently, the cutting unit 8 has only one axis of geometric rotation 18.
    [046] The new modular design of the cutting unit 8 is clearly illustrated by figures 3 and 4. The modular cutting unit 8 here has the shape of a flail cutter 11. It could, however, have taken the form of another type of unity of
    Petition 870190051815, dated 06/03/2019, p. 23/29
    11/13 cut 8, for example, with blades driven in counter-rotation. The cutting unit 8 has a support frame, half of which is shown here. The total support frame 12 is shown in figure 5. Preferably, the section of the support frame
    12, shown in figures 3 and 4, consists of a one-piece profile. However, it could also consist of several pieces.
    [047] The cutting unit 8 comprises a plurality of cutting modules
    13. Each of the cutting modules 13 has a housing 14 and an axis 15 (see figure 7), which is arranged horizontally in the housing 14 and can be operated in rotation. In the illustrations of figures 3 and 4, the axes 15 are covered by the housing 14 and therefore are not visible. Each of the axes 15 is provided with a plurality of cutting elements 16 for cutting the culture material. In the exemplary flail cutting unit illustrated 11, the cutting elements 16 are flails 17.
    [048] The cutting modules 13 are designed as separate and individually controllable units for the construction of different cutting widths 9 of the cutting unit 8 by combining different numbers of cutting modules 13 of equal and / or different widths. In the example shown, four cutting modules 13 of the same width are arranged in the represented section of the support frame 12. The cutting modules 13 could, however, also have different widths (see, for example, figures 4, 5, 10). The cutting modules 13 are arranged so that their axes 15 can be driven by one or more drives 28 and drive axes 29 (see figure 5) around the common axis of rotation 18. Between two adjacent cutting modules 13 there is each time a culture divider 26, which serves to guide the culture material into the cutting area of the appropriate cutting module
    13.
    [049] A plurality of connection plates 19 are fixed without perforation, by means of fasteners 25, to support the frame 12 in that place. The cutting modules 13 are, in turn, screwed together and to the connection plates 19. In addition
    Petition 870190051815, dated 06/03/2019, p. 24/29
    12/13 In addition, connection brackets 20 are provided to connect to the support system or connection system of the working machine 1. Other components as well - such as rollers 10, drive components, etc., can be varied variably to the support frame 12 by means of fasteners 25.
    [050] Figures 6 and 7 show additional structural details of the modular cutting unit 8. Figure 7 shows in its upper region the left part of the cutting unit 8. In the enlarged section in particular it can be seen that the axis 15 here it is shaped like a hollow shaft and the axes 15 of adjacent cutting modules 13 are connected together by a coupling 21.
    [051] Additional details of coupling 21 can be seen in figures 8 and 9. Coupling 21 has a recess 22 for fixing the adjacent shafts 15 and for transmitting torque. In the present case, opening 22 is in the form of a polygonal profile. However, other designs would also be possible. Coupling 21 has a resilient element 23 which is formed in particular of hard rubber. The two adjacent axes 15 are connected in a very small space between them by the coupling 21 comprising the element 23, which provides resilience in the direction of rotation. This means that an axis shift, for example, up to approximately 0.3 mm and an axis angle shift of up to approximately 1 ° can be compensated for between the axes 15.
    [052] Figure 10 is a full view of the modular cutting unit 8, with the left and right section of the support frame 12. The cutting unit 8 shown here thus extends across the entire cutting width 9. It is visible that the cutting modules 13 have different widths and thus a cutting unit 8 with a very variable cutting width 9 can be assembled from standard modules in the mode of a modular insertion system. The housings 14 of the cutting modules 13 may individually have an internal undulating surface to generate turbulence during operation of the cutting unit 8, thereby increasing the turnaround time

    13/13 permanence of the culture material in the cutting unit 8 and obtaining a fine cut of the culture material.
    [053] Figure 11 shows a sectional view of the support frame 12 with a cutting module 13, mounted on it. The connection plate 19 is fixed by means of fixation 25 to the support frame 12. The cutting module 13 is attached to the connection plate 19.
