    ao 1 BE2020 / 0086 Conditioning roller assembly The invention relates to a conditioning roller assembly, comprising: a first conditioning roller which is rotatably mounted on a first bearing arrangement, a second conditioning roller which is rotatably mounted on a second bearing arrangement, a holder which has a first component and a second Comprises component which are connected to one another by a hinge with an axis running parallel to the longitudinal axes of the conditioning rollers and a resilient arrangement for providing a pretensioning of the conditioning rollers, the first component being detachably connected to the first bearing arrangement and the second component being connected to the second bearing arrangement is releasably connected and the first conditioning roller can be separated from the first component together with the first bearing arrangement without dismantling the holder.
    State of the art Forage harvesters are used to harvest whole plants or their parts, which are picked up from a field during operation by means of a harvesting header, pressed together by feed rollers and fed to a knife drum, the chopping knives of which cut the plants in cooperation with a counter knife.
    Subsequently, the cut plants or parts are optionally fed to a conditioning roller assembly and conveyed by a post-acceleration device into an ejection chute, which loads them onto a transport vehicle.
    The harvested plants are usually used as fodder or to generate biogas.
    The conditioning roller assembly comprises two or more conditioning rollers which are driven in opposite directions and are movable relative to one another and which are biased towards one another by a force and between which the chopped material is passed.
    The conditioning roller assembly is used during the maize harvest to beat the grains contained in the chopped material and to improve the digestibility of the forage. {
    In the prior art, the conditioning roller assembly is composed of two component brackets, on each of which a roller is rotatably supported.
    The components of the holder can be rotated relative to one another about an axis running parallel to the longitudinal axis of the conditioning rollers and are pretensioned against one another by springs (EP 2 098 110 A2) or hydraulic cylinders (WO 2012/010396 A1).
    In other embodiments, one roller is mounted so as to be linearly displaceable with respect to the other roller (US Pat. No. 7,681,384 B2, US2004 / 0261388, EP 2 532 222 A1). The displaceable arrangements of the conditioning rollers make it possible to unfold one of the components of the holder after the conditioning roller assembly has been removed from the forage harvester for the purpose of replacing or servicing the conditioning rollers, but have the disadvantage that a linear displacement can easily lead to tilting of the movable roller when the material throughput is not uniform across the width of the conditioning roll assembly.
    In addition, the linear displaceability is structurally more difficult to achieve than a rotatable mounting of the components of the holder of the conditioning roller assembly.
    In the case of the conditioning roller assemblies with components of the bracket that are rotatably arranged relative to one another, one roller has to be dismantled from a component of the bracket for maintenance and replacement purposes.
    In the case of the conditioning roller assembly shown in EP 2 098 110 A2, which is regarded as generic, this is relatively problem-free in the case of one of the conditioning rollers, because this roller can - after loosening four screw connections - together with the associated bearing assemblies and a cover of the
    The conditioning roller can be separated from the holder.
    In the case of the other conditioning roller, the ends of which extend through holes in the side walls of a component of the bracket, on the outside of which the bearing is attached, the entire bracket, including the spring and the rotary bearing, must first be dismantled before the conditioning roller can be removed, which can be done proves to be quite time consuming.
    The subsequent assembly is similarly complex.
    Task It would therefore be desirable to improve a conditioning roller assembly of the type mentioned at the outset in such a way that removal and installation of the conditioning rollers is simplified.
    Solution According to the invention, this problem is solved by the teaching of patent claim 1, the further patent claims citing features that further develop the solution in an advantageous manner.
    A conditioning roll assembly includes: a first conditioning roll rotatably mounted on a first bearing assembly, a second conditioning roll rotatably mounted on a second bearing assembly, a bracket comprising a first component and a second component hinged to each other by a parallel to the longitudinal axes of the conditioning rollers and a resilient arrangement for providing a pretensioning of the conditioning rollers are connected, the first component being detachably connected to the first bearing arrangement and the second component being detachably connected to the second bearing arrangement and the first conditioning roller together with the The first bearing arrangement can be separated from the first component (after the connection between the first component and the first bearing arrangement has been released) without dismantling the holder, and the second conditioning roller with the second bearing arrangement can be separated from the second component (after the connection has been released) ng between the second component and the second bearing arrangement) can be separated without dismantling the bracket.
    In this way one avoids the problems mentioned above, because the second conditioning roller can also be separated from the holder after the connection between the second component and the second bearing arrangement has been released. In particular, the second bearing arrangement can be fastened to a third component of the holder, which is detachably fastened to the second component of the holder. In another possible embodiment, the shaft of the second conditioning roller can extend through an open slot in the second component of the holder so that it can be removed through the slot after the fastening between the second component and the second bearing arrangement has been released. Exemplary embodiment In the drawings, an exemplary embodiment described in more detail below is shown. 1 shows a schematic side view of a forage harvester, FIG. 2 shows a perspective view of a conditioning roller assembly in the assembled state, FIG. 3 shows a perspective view of the conditioning roller assembly with the cover of the first conditioning roller removed and the second conditioning roller separated from the second component of the holder,
    4 shows a view corresponding to FIG. 3, but from the other side; FIG. 5 shows a perspective view of the cover of the first conditioning roller, the first and second component of the holder and the third component of the holder for receiving the second conditioning roller in a separated state 6 shows a perspective view of the first and second component of the holder in the assembled state, and FIG. 7 shows a perspective view of the first and second component of the holder in the assembled state.
    A self-propelled forage harvester 10 shown in FIG. 1 is built on a frame 12 which is supported by driven front wheels 14 and steerable rear wheels 16. The forage harvester 10 is operated from a driver's cab 18 from which a header 20 suitable for harvesting stem-like plants can be viewed. By means of the header 20, which in the illustrated embodiment is a row-independent maize header, material picked up from the ground, e.g. B. corn, grain or the like is fed through upper pre-press rollers 30 and lower pre-press rollers 32 arranged in a feed assembly 36 to a chopping drum 22, which chops it into small pieces and gives it to a conveyor device 24. The crop leaves the forage harvester 10 to a trailer driving alongside via a discharge device 26 that is adjustable in its position. A conditioning roller assembly 28 extends between the chopping drum 22 and the conveyor device 24, through which the crop to be conveyed is tangentially fed to the conveyor device 24. In the following, directional information - unless otherwise mentioned - relate to the forward direction V of the forage harvester 10, such as front, rear, left and right, which runs from right to left in FIG. 1.
    The conditioning roll assembly 28 is shown in Figures 2-6.
    It comprises a first conditioning roller 38 and a second conditioning roller 40, which interact with one another during the harvesting operation in order to strike the grains contained in the chopped crop.
    The conditioning rollers 38, 40 are driven by pulleys 42, 44 which are driven by a belt (not shown) from a pulley connected to the shaft of the conveyor device 24.
    The pulley 44 is smooth because it cooperates with the back of the belt in use.
    The shaft of the conveying device 24 is driven in a manner known per se by a belt drive which also connects the internal combustion engine of the forage harvester 10 to the shaft of the chopping drum 22.
    A freely rotating idler pulley 46 for the belt used to drive the conditioning rollers 38, 40 is connected to the conditioning roller assembly 28 via an arm 94.
    The belt used to drive the conditioning rollers 38, 40 is tensioned in a manner known per se, for which purpose a further freely rotating roller (not shown) or the deflection roller 46 can be used.
    The conditioning rollers 38, 40 are shown one above the other in FIGS. 2 to 6, but can also be spaced apart horizontally or arranged on a line running obliquely forwards and upwards, as shown in FIG.
    The conditioning roller assembly 28 is known per se (cf.
    EP 2 364 586 A1 and EP 2 363 016 A1) can be removed from the forage harvester 10 as a whole.
    It would also be conceivable to swap the position of the conditioning rollers 38, 40 in FIG.
    The conditioning rollers 38, 40 are attached to a holder 48, which in turn comprises a first component 50, a second component 52 and a third component 54.
    A first bearing arrangement 56 is fastened to a flange 60 of the first component 50 by screws 62.
    The first bearing arrangement 56 serves to rotatably support the first conditioning roller 38 on the first component 50. A cover 64 of the first conditioning roller 64 is also removably attached to the first component 50.
    As can be seen from the following figures and description, the second component 52 is pivotable with respect to the first component 50 about an axis extending parallel to the axes of the conditioning rollers 38, 40 and by a resilient arrangement 66, which is also operated by a hydraulic cylinder (which also could act on a tensioning roller of the belt for driving the rollers 38, 40) could be replaced or supplemented, biased with respect to the first component 50. The resilient arrangement 66, made up of disc springs in the example shown, pretensions the conditioning rollers 38, 40 against one another during operation, so that they can move apart against the force of the resilient arrangement 66 depending on the throughput of the crop. An eccentric mechanism is connected to an actuator 68 in order to adjust the smallest possible gap between the conditioning rollers 38, 40. This eccentric mechanism is shown in more detail in FIGS. 5 to 7 and varies the position of the axis of rotation of the second component 52 with respect to the first component 50. A ring 80 is between the flange 60 of the first component 50 and a flange 76 that is assigned to the second component 52 is arranged to limit the inward path of the resilient arrangement 66 (and thus also the shortest distance between the conditioning rollers 38, 40). The upper end of the resilient arrangement 66 rests on the side of the flange 76 facing away from the ring 80, the other end of which is supported on the upper side of the flange 60 of the first component via a bolt 82 and a nut arrangement 84.
    The second conditioning roller 40 is supported on a second bearing arrangement 58, which in turn is fastened to the third component 54 by screws 70. The third component 54 is in turn detachably attached (by screws) to the second component 52, on the one hand by a longer bolt 74 on the flange 76, which protrudes laterally from the second component 54, and on the other hand via an angle 86 on one with the second component 54 paired
    Retaining plate 72 attached, which is connected to an arrangement 76 which serves to support the conditioning roller assembly 28 during installation and removal from the forage harvester 10. A further detachable connection of the third component 54 to the second component 52 is made by a bar 88, which is connected by screws 90 to the side wall of the third component 54 and the side wall of the second component 52, on its side adjacent to the resilient arrangement. The arm 94 of the deflection roller 46 is also attached to the third component 54.
    The described bearing arrangements 56, 58 and components of the components 50, 52, 54 are found at both ends of the conditioning rollers 38, 40.
    FIGS. 3 and 4 show the conditioning roller assembly 28 in the expanded state, which enables the conditioning rollers 38, 40 to be removed and replaced if necessary. For this purpose, all that is necessary to dismantle the first conditioning roller 38 is to dismantle the cover 64 and to loosen and remove the screws 62, so that the connection between the bearing arrangement 56 and the first component 50 is separated. In contrast to the prior art according to EP 2 098 110 A2, the second conditioning roller 40 can also be dismantled relatively quickly and easily, and in particular without dismantling the holder 48, by first separating the third component 54 from the second component 52 (by loosening and removing the screws 90 and the screw connection of the bolt 74 and the bracket 86), so that the screws 70 are then freely accessible in order to separate the connection between the bearing arrangement 58 and the third component 54 and to remove the second conditioning roller 40. A dismantling of the holder 48, which is still required in the prior art, is thus omitted. The reassembly is done in reverse order.
    FIG. 5 shows the components 50 to 54 with the conditioning rollers 38, 40 dismantled. The first component 50 comprises two side walls 96 which are secured by the eccentric mechanism (in FIGS
    6 and 7) are pivotally connected to the second component 52, and to each of which a flange 60 is welded, using a stiffening bracket 98. In addition, brackets 100 protrude from the side walls 94, between which the bearing arrangement 56 is received. Two side walls 96 of the first component 50 are provided, which are each arranged at one end of the first conditioning roller 38 and are not connected to one another directly (but rather via the second component 52).
    The second component 52 also comprises two side walls 102, on each of which a flange 76 is welded on the outside using a supporting bracket 104. The two side walls of the second component 52 are connected to one another by transverse strips 106, 108 designed as an angle profile.
    The third component 54 also comprises two side walls 110, which are connected to one another by a cover 112 of the second conditioning roller 40, and from which flanges 112, 114 protrude outwards, at which the connection to the second component 52 (ie to the bolts 74 and the angle 86), while the third connection with the second component 52 takes place via the strip 88 directly on the side wall 110 and the screws 90, 92 pass through the holes 116 in the side walls 102 of the second component 52 and the side walls 110 of the third Component 54 extend.
    FIG. 6 shows the first component 50 and second component 52 in the assembled state, while FIG. 7 shows them in the expanded state. The actuator 68 includes an adjusting motor 118, the housing of which is connected to the transverse bar 108 via an arm 132. The adjusting motor 118 connected to a cable 130 has an output shaft 120 which is coupled to a spindle drive 128, which converts the rotary movement of the shaft 120 into a linear movement and transmits it to a lever 122, which extends transversely between the side walls 102 of the second component 52 extending shaft 124 is coupled. On the one hand, the shaft 124 is mounted on the side walls 102 so that it can rotate about its longitudinal axis and, on the other hand, is connected to eccentrics 126 which are each located in a corresponding opening 134 (see
    FIG. 6) are located in the side wall 96 of the first component 50. This enables the above-described adjustment of the minimum possible gap between the conditioning rollers 38, 40 and the aforementioned rotation of the second component 52 relative to the first component 50 about the axis extending parallel to the axis of the conditioning rollers 38, 40, because the eccentric 126 forms with it of the opening 134, the hinge about which the components 50, 52 are rotatable relative to one another. The actuation of the adjusting motor 118 can be carried out by an operator by means of an interface arranged in the cab 18 or by an automatic system based on properties of the crop that are detected by sensors.
