    Harvesting machine
    The present invention relates to a harvesting machine, with a pick-up device for picking up harvested goods, wherein the pick-up device comprises a spine roller, which transports harvested goods from the bottom of a transport channel, the transport channel comprising a movably suspended upper channel boundary, which at least has a roll-in roller and comprises a guide wall element subordinate thereto and is adjustable with regard to the distance of the spine roller in dependence on the thickness of the incoming harvesting carpet.
    For goods transport along the so-called pickup, harvesting machines usually use a guide device which can comprise one or more roll-in rollers as well as a baffle connecting downstream therefrom, as a result of which the flow of goods flowing into the harvesting machine is limited upwards, such that that on the one hand the engagement of the spines of the spine roller and thus their transporting effect is ensured and on the other hand the transfer of the flow of goods to the transport rotor usually provided downstream of the spine roller is supported.
    Said guiding device is herein usually adjustable with regard to its distance from the spine roller, it being known in particular to pivot the baffle plate at its rear, ie downstream end, such that the front side can pivot up and down and the run-in accordingly becomes larger or smaller in order to be able to adapt the guide device to different harvested carpet material. Depending on the swath strength and the driving speed, a certain thickness of the picked-up harvest carpet is created, which comes over the spine roller in the transport channel. In accordance with these thickness variations, the guide device must be modified with regard to its distance from the spiked roller, in particular the bottom of the conveyor, in order to adapt the height of the conveyor or conveyor to the carpet thickness.
    In the aforementioned solution which provides for a pivotable suspension of the baffle plate at its downstream end, only the lead-in area of the transport channel can be adapted to the thickness of the harvested carpet, but there is a cross-sectional rejuvenation of the transport channel towards the downstream end of the baffle plate , as a result of which the crop is strongly compressed or blockages can occur. It has therefore already been proposed to circumvent this problem with the aid of a four-rod mechanism in which the baffle plate is pivotally suspended by a pair of hinges arranged as a parallelogram, such that the baffle plate can be moved away from the spine roller without the hinge-type angular rotation and transport passage at the front end and at a rear end of the baffle plate can be evenly enlarged. Such a parallelogram hinge suspension of the downholder or baffle plate is, however, relatively expensive with regard to the number of the hinge axes and components. In addition, the parallel guide of the baffle plate can only be used to a limited extent in order to achieve an even depression of the crop flow. In particular, with strongly varying feed flow volumes, that is to say with harvested carpets which rapidly become thicker and thinner, it leads to uneven pressing. A strongly increasing harvest carpet in the lead-in area also leads to an increase of the channel passage in the lead-out area of the baffle plate, where no food increase has yet arrived, while, conversely, the guide device cannot yet move downward in the lead-in area, in order to achieve a strongly decreasing food flow to press it still on the spiked roller when there is still a crop accumulation in the lead-out area that has not yet been transported over the lead-out area of the baffle plate.
    From EP 1 733 609 A1 a pickup of a harvesting machine is known, which is provided with a guide device comprising a lead-in roller and a guide wall element as an upper transport channel boundary, the guide wall element being formed from an assembly of grid bars. Said grating rods are pivotally suspended from an arm, which also carries the lead-in roller and can be changed with regard to the distance to the spine roller by means of a multiple pivoting hinge mechanism. The multiple-hinged hinge mechanism is relatively complicated. Moreover, due to the hinged suspension of the grid bars, only an insufficient pressing force is obtained.
    EP 1 362 506 discloses a crop receiving device with a spine roller, which is provided with a cardanically suspended support wheel and a sliding shoe connected thereto.
    From EP 1 417 879 a pickup with a spine roller is known, which is provided with a hold-down roller, which is rotatably mounted on a movable extension, in order to make it possible to move upwards with larger quantities of crops.
    From EP 1 741 330 a pick-up device with a spine roller is known, which is provided with a roll-down holder with a plurality of holding rollers, which is suspended from a swing in height-movable manner, the pivotal axis of which is provided downstream of the spine roller. The spiked roller itself is also suspended from a swing, which is not only hinged in height, but also telescopically adjustable. As a result, different configurations of the passage size between the downholder and spine roller and conveyor base can be obtained, but the device is very complicated.
    EP 1 790 206 A1 discloses a pick-up with a spiked roller, which is provided with a plurality of hold-down rollers, one part of which is pivotally suspended and another part is fixed. Grating is provided between the rollers, each of which is pivotally suspended at their front end.
    From DE 10 2004 023 760 B4 a pickup of a baling press is known, which is provided with a downholder with a lead-in roller and a baffle plate. However, the thickness and height of the transport channel are obtained here by adjusting the transport channel bottom.
    The present invention therefore has for its object to provide an improved harvesting machine of the type mentioned in the preamble, which avoids the disadvantages of the prior art and last advantageously further developed. In particular, improved run-in control of the harvested harvested carpet material with a downholder must be obtained which, with a simple construction, also allows a uniform downward pressure with strongly varying harvested goods flows.
    According to the invention, said object is achieved with a harvesting machine according to claim 1. Advantageous embodiments according to the invention are the subject of the dependent claims.
    It is proposed to suspend the guide device in such a way that the passage dimensions can be increased and decreased both at the entrance and exit of the guide device, and then not forced to the same extent, but independently of each other, so that the passage size of the entrance changes as required. can be changed than in the outlet of the guide device. According to the invention, the at least one lead-in roller and the guide wall element form a jointly suspended building component, which is pivotally suspended on a supporting pivot on a first pivot axis and which is also pivotally suspended on a second pivot axis parallel to the first parallel pivot axis. By combining the at least one lead-in roller and the guide wall element into a common assembly, a simple embodiment of the suspension can be obtained. Due to the tiltability of the assembly on a again pivotable support arm, like a rocker, not only the passage size, but also the angle of the guiding device and the upper channel limit formed thereby can be varied, so that a uniform pressing down of the incoming harvesting carpet also strongly varying crop flow volumes can be achieved. In particular, tilting means that a rocker can change the passage size in the lead-in area differently than in the lead-out area, as a result of which the setting angle of the guide device can be suitably adjusted to the transport material variations. At the same time, a sufficient downward pressure force is ensured in all areas by the coupling pivoting in accordance with a rocker, since in the lead-in area and in the lead-out area a force exerted on the assembly by the crop on the assembly causes the rocker to be depressed at the other end. For example, if the downstream end of the guide wall element rockers upwards, the lead-in roller will rock down on the opposite side of the rocker shaft. However, if this is not possible there, because, for example, a thicker harvesting carpet arrives, then the rocker can also pivot upwardly to support the rocker. Corresponding or reversed hinge movements are carried out analogously to other harvested carpet thickness distributions, in order to obtain a uniform downward pressure in each case.
    In a further embodiment according to the invention, the assembly, pivotally suspended in accordance with a rocker, comprising said guide wall element and the at least one walk-in roller in its angular position becomes at least partially freely movable. In particular, the assembly pivotally suspended in accordance with a rocker can be designed in its angular position to be self-adjusting in order to adjust the angular adjustment of the component with respect to the bearing arm in accordance with the contour of the incoming crop carpet. If necessary, tilting in accordance with a rocker of said assembly relative to the bearing arm can be biased by a suitable biasing device, for example in the form of a spring device, such that with a hinge from a neutral position corresponding biasing forces can be overcome, in particular in the absence of tilt forces from the harvested carpet is taken back to the corner position. Nevertheless, the said assembly itself can, depending on the incoming harvesting carpet, look for a suitable angular position, i.e. there is no coercive control, as is the case with a parallelogram hinge guide or is obtained by angular drive. Due to the uncontrolled mobility, a more uniform pressure pressing down the harvesting group carpet can be obtained. In a further embodiment according to the invention, the free mobility can nevertheless be limited, for example by hinged stops, to prevent over-hinging in a non-sensible angular position.
    Alternatively or additionally to the free or self-adjusting tiltability according to a rocker by said assembly relative to the support arm, the support arm itself can also be suspended in its angular position itself and / or at least partially freely movably hinged, in order to be independent of the aforementioned angular position of the rocker-like assembly to be able to obtain a total change in the passage dimensions when the incoming crop carpet requires this. In a further embodiment according to the invention and here too the bearing arm mentioned are provided with a biasing device, for example in the form of a spring device, in order to obtain a biasing voltage in a desired neutral position, wherein here the neutral position is in particular a base position following the spine roller. . As an alternative to a spring device, the carrying arm can also be held down only by the weight of the carrying arm and the assembly attached thereto. Depending on the configuration and the weight of the components used, however, a spring device or another biasing device can be advantageous in order to obtain the necessary hold-down pressure.
    The free pivotability, in particular the prestressed pivotability of the said support arm can advantageously be limited, for example by pivot stops, to prevent pivoting of the support arm to non-meaningful positions, in particular such that a minimum passage size and a maximum passage size can be achieved. the stated limit is given.
    The possibility of tilting according to a rocker of the aforementioned assembly comprising the at least one lead-in roller and the at least one guide-walking element is obtained by positioning the said first hinge axis between said lead-in roller and the downstream end of the guide-walking element, so that the assembly thus formed segment upstream of the hinge axis and a segment downstream of the hinge axis. In particular, said first pivot axis can be provided approximately midway between the front lead-in roller and the downstream end of the guide wall element. Alternatively or additionally, arranging said first pivot axis approximately in the area of the front end segment of the baffle plate may be advantageous.
    In a further embodiment according to the invention, said guide wall element can be a flat baffle plate. Alternatively, a staff assembly, for example a lattice grating device or something similar, for example a perforated shaped whole, can be provided, wherein the embodiment is advantageously such that both harvestable goods to be picked up from the guide wall element and / or its cover leaf are held down and / or along the transport channel led.
    The said at least one run-in roller can be designed continuously over the full width of the spine roller in accordance with a roller. Alternatively, a plurality of rollers can also be arranged on a common axis next to each other, which are more or less far apart from each other, wherein here too the positioning is designed such that the incoming crop material in total substantially over the full width of the spiny roller is held down. In addition, a plurality of such rollers, which may optionally be formed by a plurality of roller elements on a common axis, may be provided one after the other, that is to say in the conveying direction in different areas, wherein, for example, a hold-down roller is substantially directly at the front end of the guide wall element can be provided, while a second roll can be provided downstream and at a distance from said first roll. Advantageously, even with the use of a plurality of run-in rollers, these run-in rollers with the aforementioned guide wall element are assembled into a common assembly pivotally suspended in the aforementioned manner, which rocker can be adjusted at the same time.
    An advantageous further embodiment according to the invention is the at least one run-in roller assigned to the spine roller to press down the crop in the area of the spine roller or to press it on the spine roller. In particular, the at least one lead-in roller viewed in the direction of travel can be provided in a front, upper quadrant of the spine roller, in particular arranged in the area of this front upper quadrant, to press the crop against this peripheral part of the spine roller.
    In a further embodiment according to the invention, the device can advantageously be designed such that - depending on the position of the support arm - the first pivot axis, why the rocking function can be performed, in the region of the spine roller, will be above the same, whereby the lead-in roller extends over the front end of the spiked roller and the guide wall element extends over the rear end of the stab roller, both seen in the direction of travel.
    The guide wall element extends advantageously from the spine roller at least to behind the spine roller, where the crop is delivered with flow from the spine roller. In particular, the baffle plate may extend downstream to approximately the lead-in area of a conveyor rotor which is provided subsequent to the spine roller.
    The second pivot axis, about which the rocker-bearing support arm is pivotable, can be positioned in substantially different positions, wherein in an advantageous embodiment according to the invention a positioning of the second pivot axis in an area above the spine roller center point and / or in a central region between spine roller center point and transport rotor can be provided. In particular, the said carrying arm can be hingedly attached with the said second pivot axis to a spindle roller carrier pivotally suspended like a swing, by means of which the spine roller is height-adjustable. The second pivot axis can in this case be provided in particular in a central region of this spine roller carrier between the spine roller center and carrier pivot axis. Owing to the additional tiltability in accordance with a rocker of the aforementioned assembly formed from a lead-in roller and a guide wall element, the said supporting arm does not have to have an excessively long length, since the rocker-like tiltability of the component does not require parallel guidance and in particular the cut-through dimension at the lead-in end and adjusts independently at the outlet end, even when the carrying arm is shorter. A compact suspension can hereby be obtained. In particular, the said carrying arm can have a length that is shorter than the length of the guide wall element in the direction of transport. However, in essence, other embodiments with a greater length and different positioning of the pivot axes are possible, so that here a totally greater degree of freedom is achieved in the design of the suspension, in particular suspension points.
    The present invention is explained in more detail below with reference to a preferred exemplary embodiment and with accompanying drawings. In the drawings:
    FIG. 1: a side view of a harvesting angle machine transversely to the direction of travel according to an advantageous embodiment of the invention, wherein the harvesting machine is only partially shown and its receiving device for receiving the harvesting material from the ground is shown.
    The harvesting material machine shown in the figure is designed as a baling press, which forms the harvested material taken from the ground into bales in a bale forming chamber 2 in a manner known per se. However, the harvesting machine can alternatively also be formed as a loading wagon or in the form of a trailer device or also a self-propelled device, which pick up halved and / or leaf-shaped harvesting goods from the soil and further process them in particular between-store.
    As Fig. 1 shows, the pick-up device 3 comprises a pick-up roller 4 for receiving crop material from the soil, with which the crop lying on the soil can be picked up. The said spine roller 4 can in this case comprise spines which, when loaded on their orbit, can also move around unloaded.
    The said spine roller 4 is herein suspended from a spine roller carrier 5, which is rock-shaped and is pivotally suspended about a pivot axis 6 extending transversely to the direction of travel, such that the spine roller 4 is adjustable in height, in order to obtain a better ground adjustment and for be able to pivot the street transport upwards.
    The harvested material taken up by the spiked roller 4 is transported from the spiked roller 4 over the top into a transport channel 7, which leads to a transport rotor 8, to which the harvested material is transferred from the spiked roller 4. Said transport rotor 8 can be provided with knives in a manner known per se in order to cut the harvested material. The crop is transported from the transport rotor 8 into the aforementioned bale forming chamber 2.
    In the receiving area of the spine roller 4, a guide device 9 is provided above the spine roller 4, which presses down the incoming crop and forms the run-in of said transport channel 7 and forms an upper boundary of the channel in said run-in area.
    As Fig. 1 shows, said guide device 9 comprises a lead-in roller 10 as well as a guide wall element 11, which is provided downstream of said lead-in roller 10 and to which, possibly through a remote passage or directly adjacent, connects. The lead-in roller 10 and / or the guide wall element 11 can advantageously extend over the entire width of the spiked roller 4, wherein possibly several sections can be provided.
    The lead-in roller 10 and the guide wall element 11 are herein combined into a joint hingedly suspended assembly, wherein in an advantageous further embodiment according to the invention the lead-in roller 10 and the guide wall element 11 can be rigidly connected to each other.
    As Fig. 1 shows, said assembly comprising the lead-in roller 10 and the guide wall element 11 is suspended from a supporting arm 13 according to a rocker around a first pivot axis 12, a pair of supporting arms being of course also provided here on the right and left. Said carrying arm 13 is itself also hingedly suspended, namely on a second hinge pin 14, which extends parallel to the first hinge pin 12 and can in particular be arranged transversely to the direction of travel. Advantageously, the carrying arm 13 is herein provided on the swing-shaped spine roller carrier 5, so that with a height-adjustable movement of the spine roller 4 the guide device 9 is moved in a corresponding manner.
    The hinge range of the carrying arm 13 is limited by a hinge stop 15 at least downwards, in particular in the direction of the spine roller, so that a minimum gap size is ensured between the guide device 9 and the spine roller 4.
    As shown in Fig. 1, in the operating position of the pick-up device 3 with a corresponding arrangement of the spine roller carrier 5, the second pivot axis 14 is provided above the center of the spine roller 4, the second pivot axis 14 being approximately in a central portion of the spine roller carrier 5 between its spine roller center. and the rocker shaft 6 is provided.
    The first hinge pin 12, depending on the position of the carrier arm 13, viewed in the direction of travel in the front region of the spine roller 4, will be above the same, such that the rocker axis of the rocker-like component is assigned a front, upper quadrant of the spine roller and the crop flow presses on the spiny roller in that quadrant.
    The run-in roller 10 here extends, viewed in the direction of travel, beyond the spine roller 4, in particular directly to the front edge area of the spine roller 4. The guide wall element 11 extends rearwardly over the spine roller and can in particular extend approximately in a transfer area the transport rotor 8.
    The following mobility is hereby obtained for the guide device 9: due to the pivotability of the bearing arm 13 about the second pivot axis 14, the guide device 9 as a whole can be moved away from the spine roller, in particular from the bottom of the transport channel, so that the passage size in the lead-in area and in the lead-out area of the guide device 9 can be uniformly increased or decreased.
    As an alternative or in addition to this pivoting of the carrying arm 13, the building component comprising the run-in roller 10 and the guide wall element 11 can swing up and down about the first pivot axis 12 with respect to the carrying arm 13, as a result of which the adjustment angle of the guiding device 9 can be changed. Accordingly, the passage size can be changed differently in the lead-in area than in the lead-out area, whereby adaptation to the incoming harvesting carpet can be obtained and a uniform downward pressure on the harvesting material can be achieved.
