    Agricultural implement and method for transferring the same between a transport position and a Arbeitsstellunq
    The invention relates to an agricultural implement such as e.g. an attachment of an agricultural harvesting vehicle and a method for transferring the same between a transport position and a working position.
    Agricultural implements are known from the prior art, which have a first, middle and fixed implement section, on both sides of the first implement section adjacent to the same and displaceable second implement sections and to the respective second implement section opposite to the first implement section adjacent third implement sections, which are displaceable relative to the respective second implement portion. Then, when the agricultural implement is an attachment for an agricultural harvesting vehicle, such as a corn header for a forage harvester, the middle, first implement section is also referred to as a central trough and the adjacent movable work implement sections are also termed a cantilever. The invention is not limited to trained as attachments agricultural implements. The agricultural implement may also be a tillage implement or a haymaking machine, such as a tillage machine. to act a swather.
    From EP 1 464 214 B1 a harvesting vehicle with an attachment is known which has a middle, first implement section and on both sides thereof two implement sections, namely a second implement section adjacent to the middle implement section and a third implement section adjacent to the respective second implement section , The second work implement sections can be displaced by a respective pivot axis relative to the middle, first work implement section, wherein the third work implement sections adjoining the second work implement sections opposite to the first, middle work implement section also change over the respective second work implement section
    Swivel axes are displaced. The working implement sections of the work implement are displaceable relative to one another between a working position and a transport position such that the third work implement sections adjoining the stationary, middle, first work implement section and the third work implement sections adjoining the second work implement sections are obtuse-angled or roof-like in the transport position ,
    Another attachment of an agricultural harvesting vehicle is known from EP 2 111 740 B1. Thus, this attachment comprises a first, middle, stationary implement section and adjacent to both sides of the first implement section second and third implement sections, which are each displaceable, namely such that the second implement sections are displaceable to the first implement section each about a pivot axis, and that the third work implement sections, which adjoin the first work implement section adjoining the respective second work implement section, are each displaceable about a pivot axis relative to the respective second work implement section. The implement sections are asymmetrically displaceable, namely such that in the transport position all work implement sections are arranged in four mutually parallel layers.
    The working devices known from EP 1 464 214 B1 and EP 2 111 740 B1, each of which has a middle stationary working part and two displaceable lateral working device sections on both sides, already permit an effective transfer of the working device between the transport position and working position. However, there is a need for a novel, agricultural implement with a larger working width and more than five implement sections, which also allows a simple, effective and quick displaceability of the implement sections between the transport position and the working position.
    From US 4 191 260 a pulled agricultural implement is known, with a plurality of juxtaposed in a working position sections, which can be moved for transport in five superimposed planes.
    On this basis, the present invention has the object to provide a novel agricultural implement.
    This object is achieved by an agricultural implement according to claim 1. Opposite to the respective second implement section is adjacent to the respective third implement section in each case a fourth working device section, which is displaceable relative to the respective third implement section about a pivot axis. The second, third and fourth implement sections positioned to a first side of the first implement section and the second, third and fourth implement sections positioned to a second side of the first implement section have symmetrical support members for mowing organs and conveyors relative to the first implement section, with respect to the first Working device section are folded symmetrically such that the implement sections are arranged in a transport position in four superimposed layers.
    The working device according to the invention has at least seven implement sections, namely the same over the middle, first implement section as well as on both sides thereof via in each case three displaceable implement sections. The second, third and fourth work implement sections adjoining on both sides of the middle, first work implement section permit a simple, effective and rapid displacement of the work implement between the work position and the transport position due to their symmetrical support elements relative to the first work implement section and their symmetrical foldability.
    According to an advantageous development of the invention, in the transport position, the support element of the first implement section is positioned in a first position, wherein the support elements of the second implement sections are positioned together in a second position, wherein the support elements of the third implement sections are positioned together in a third position, and wherein the support members of the fourth implement portions are positioned together in a fourth position. This is to ensure a simple, effective and fast Verlagerbarkeït the implement between the transport position and the working position preferred.
    Preferably, for transferring the implement between a transport position and a working position, the second implement sections relative to the first implement section each pivotable through 180 °, wherein the third implement sections relative to the respective second implement section are also each 180 ° pivotable, and wherein the fourth implement sections relative to the respective third working device section are each pivotable by 150 ° to 170 °, so that the support elements of the first, second and third implement sections parallel to each other in the transport position and the support elements of the fourth implement sections in the transport position obtuse or roof-like. This embodiment has the advantage that the pivot axes between the fourth implement sections and the third implement section can be arranged lower, resulting in a better viewing cone for the driver of the harvesting vehicle. This configuration therefore allows in the transport position of the implement a better view of the road ahead of the harvesting vehicle roadway. In particular, the visibility on lateral areas of the road ahead of the harvesting lane improves.
    Preferably, the mowing organs and conveying elements accommodated by the carrying elements of the second, third and fourth working implement sections of the working implement are distributed symmetrically relative to the first working implement section. This is simple and allows it to meet requirements for a maximum allowable width of the implement in the transport position.
    Alternatively, the cutting elements and / or conveying elements received by the carrying elements of the second and / or third and / or fourth working implement sections of the working implement are distributed asymmetrically relative to the first working implement section. With this embodiment of the invention can be realized in the width even more compact or narrow-built transport position for the implement.
    According to an advantageous development of the invention, the second implement sections are displaceable relative to the first implement section respectively by a displacement device, wherein the fourth implement sections are displaceable relative to the respective third implement section respectively by a displacement device, and wherein the third work implement sections each with the first implement section via a zugkraftübertragendes element is coupled such that when initiated by the respective displacement device displacement of the respective second implement portion relative to the first implement portion of the respective third implement portion positively coupled to the displacement of the respective second implement portion is displaced. For the displacement of the second work implement sections relative to the first work implement section and for the displacement of the third work implement sections relative to the second work implement sections, a reduced number of displacement devices is sufficient due to the forced coupling between the third work implement sections and the first work implement section. As a result, a simpler structure for an agricultural implement can be realized. In addition, the kinematic coupling significantly reduces the power requirement in the respective displacement device, since the motion sequences or effective forces advantageously support one another.
    The method for transferring the agricultural implement between the transport position and the working position is defined in claim 12. The inventive method allows a simple, effective and fast displacement of the implement between the working position and the transport position.

    With reference to Figs. 1 to 7, the invention will be described for a header formed as a corn header of a forage harvester, but the invention is not limited thereto.
    A header has a plurality of implement sections, hereafter called header sections, that is, a first, fixed, central header section, and on both sides thereof via displaceable header sections. Typically, the fixed header portion is referred to as a center tray, wherein on both sides of the fixed header portion arranged displaceable header portions are also referred to as a boom.
    1a to 4b show details of a first attachment 10 for an agricultural harvesting vehicle, wherein in FIGS. 1a to 4b a first, fixed attachment section 11, adjoining this first attachment section 11, movable relative to the first attachment section 11 second attachment sections 12a, 12b, third attachment sections 13a, 13b adjacent to the second attachment section 12a, 12b opposite to the first attachment section 11 and fourth attachment sections 14a, 14b adjacent to the third attachment sections 13a, 13b opposite the respective second attachment section 12a, 12b are shown.
    In the illustrated embodiment, in which the attachment 10 is designed as a corn header, each attachment sections 11, 12a, 12b, 13a, 13b, 14a, 14b each have a support element 18, which in each case at least one rotating or circumferentially driven cutting member 19 and / or each carrying a conveying member 20.
    The mowing members 19 are also referred to as mowing and drawing-in organs and the conveying members 20 also as transverse conveying members.
    The second attachment sections 12a, 12b of the attachment 10 shown in FIGS. 1 to 4 are displaceable relative to the first attachment section 11 by a respective pivot axis 15a, 15b. The third attachment sections 13a, 13b of the attachment 10 are displaceable relative to the respective second attachment section 12a, 12b about a pivot axis 16a, 16b. The fourth attachment sections 14a, 14b of the attachment 10 are displaceable relative to the respective third attachment section 13a, 13b about a pivot axis 17a, 17b.
    The second, third and fourth header sections 12a, 13a and 14a positioned to a first side of the middle or first header section 11 of the header 10 and the second, third and fourth header sections 12b, 13b and 14b positioned to an opposite second side of the first header section 11 have, based on the first header section 11, symmetrical support elements 18 for the Mähorgane 19 and / or the conveying members 20 on.
    The support elements 18 of the attachment sections 12a, 13a, 14a, 12b, 13b, 14b positioned on both sides of the central attachment section 11 of the attachment 10 are symmetrically foldable relative to the first attachment section 11, namely such that the attachment sections 11, 12a, 13a, 14a, 12b, 13b, 14b of the attachment 10 are arranged in the transport position in four superimposed layers.
    Thus, in particular Fig. 4a, 4b, which shows the attachment 10 of Fig. 1a to 4b in the fully folded transport position, are removed, which is positioned in the transport position, the support member 18 of the first, central header portion 11 in a first, lower position in that the support elements 18 of the two second header sections 12a, 12b are positioned together in a second position arranged above the first layer such that the support elements 18 of the third header sections 13a, 13b are jointly positioned in a third position positioned above the second layer, and that the support elements 18 of the fourth header sections 14a, 14b are positioned together in a fourth, above the third layer position.
    In the working position of Fig. 1a, 1b all supporting elements 18 of all header sections 11, 12a, 13a, 14a, 12b, 13b, 14b are arranged side by side in one layer.
    In the embodiment of FIGS. 1 a to 4 b, for transferring the implement 10 between the transport position and the working position, the second attachment sections 12 a, 12 b pivot about 180 ° relative to the first, middle, stationary implement section 11 about the pivot axes 15 a, 15 b.
    The third attachment sections 13a, 13b are in the embodiment of FIGS. 1a to 4b relative to the respective second attachment section 12a, 12b about the respective pivot axes 16a, 16b also pivotable in each case by 180 °.
    The fourth attachment sections 14a, 14b are in the exemplary embodiment of FIGS. 1a to 4brelative to the respective third attachment section 13a, 13b in each case by 150 ° to 170 ° pivotable.
    In the embodiment of FIGS. 1a to 4b, this ensures that the support elements 18 of the first, second and third attachment sections 11, 12a, 13a, 12b, 13b in the transport position (see FIGS. 4a, 4b) run parallel to one another, whereas the support elements 18 of the fourth header sections 14a, 14b in the transport position obtusely or roof-like to each other. In this way, a compact transport position of the attachment 10 can be realized with a good visibility cone for a driver of the header 10 receiving harvester.
    As can be seen in FIGS. 1 a to 4 b, the support element 18 of the middle header section 11 accommodates four mowing members 19 and four conveying members 20. The support elements 18 of the attachment sections 12a and 12b each receive two mowing members 19 and one conveying member 20 each. The support elements 18 of the third header sections 13a, 13b each receive two mowing members 19 and two conveying members 20 each. The support elements 18 of the fourth header sections 14a and 14b each receive a mower 19. In this case, the mowing devices 19 assigned to the fourth attachment sections 14a and 14b have larger diameters than the cutting elements 19 assigned to the other attachment sections 11, 12a, 12b, 13a, 13b.
    The above number and division of the mowing members 10 and conveyor members 20 on the header sections 11, 12a, 12b, 13a, 13b, 14a, 14b is exemplary in nature. Thus, the central recess or the first attachment section 11 may also have only two mowing members 20.
    In the embodiment of FIGS. 1a to 4b, the mowing members 19 and conveying members 20, based on the first, middle header portion 11 symmetrically distributed to all header sections 11, 12a, 13a, 14a, 12b, 13b, 14b.
    Figures 5 and 6 show details of an alternative attachment 10 in which the mowing members 19 associated with the fourth header portions 14a and 14b have identical diameters as the mowing members 19 associated with the other header portions 11, 12a, 13a, 12b, 13b in which also the fourth attachment sections 14a, 14b each have a conveying member 20.
    In this way it is then possible to displace the attachment sections of the attachment 10 into the transport position shown in FIG. 6 such that the fourth attachment sections 14a, 14b can also be pivoted through 180 ° relative to the respective third attachment section 13a, 13b, so that then all the support elements 18 all implement sections 11, 12a, 13a, 14a, 12b, 13b, 14b in the transport position parallel to each other.
    To ensure a good viewing cone for a driver, however, the transport position of FIG. 4 relative to the transport position of FIG. 6 is preferred because in the transport pitch of Fig. 4, the pivot axes 17a, 17b, by which the fourth implement portions 14a, 14b relative to the third header sections 13a, 13b can be pivoted deeper down towards a roadway, thereby providing a better field of view for the driver of a harvester.
    A further embodiment of an attachment 10 according to the invention is shown in FIG. 7, which differs from the attachments 10 of FIGS. 1 a to 4 b or FIGS. 5 and 6 in that the support elements 18 of the second and / or third and / or fourth header portions 12a, 12b, 13a, 13b, 14a, 14b recorded mowing members 19 and / or conveying members 20, based on the first, fixed header section 11 are distributed asymmetrically.
    Thus, in the attachment of Fig. 7, which is shown exclusively in the transport position, in the region of one of the third header sections 13a or 13b that conveying member 20, which is positioned adjacent to the respective pivot axis 16a and 16b, from the respective third header section 13a and 13b shifted to the respective adjacent second header portion 12a and 12b, so then in the transport position of one of these conveying members 20 is directed upwards and another downwards.
    With the attachment of Fig. 7 can then be reduced in the transport position, the width of the implement or attachment. This is particularly advantageous for transport on public roads.
    To shift the implement 10 according to the invention from the unfolded working position into the folded transport position, the second, third and fourth attachment sections 12a, 13a, 14a positioned to the first side of the attachment section 11 are synchronously positioned with the second attachment side of the first attachment section 11 second, third and fourth header sections 12b, 13b, 14b displaced.
    Here, as can be seen from the sequence of FIGS. 1 a to 4 b, the procedure is such that, during a displacement, starting from the working position (see FIGS. 1 a, 1 b) into the transport position (see FIGS. 4 a, 4 b), first the fourth working implement sections 14a, 14b are displaced into the position shown in FIGS. 2a, 2b, and the second and third working implement sections 12a, 13a, 12b, 13b are subsequently displaced relative to the first working implement section 11. In the case of the reverse displacement from the transport position to the working position, first the second and third working device sections 12a, 13a, 12b, 13b and only then the fourth working device sections 14a, 14b are displaced.
    In contrast to this, however, it is also possible to displace the fourth implement sections 14a, 14b at least in sections synchronously or simultaneously with the second and third attachment sections 12a, 13a, 12b, 13b, thereby requiring the transfer of the implement between the transport position and the working position Time can be further reduced.
    In the exemplary embodiments of FIGS. 1 to 7, the second attachment sections 12a, 12b are displaceable relative to the first attachment section 11 about the pivot axes 15a, 15b by means of a respective displacement device 21 (see FIGS. 1a, 1b).
    The fourth header sections 14a, 14b are displaceable relative to the third header sections 13a, 13b about the pivot axes 17a, 17b by means of a respective further displacement device 22 (see FIGS. 1a, 1b).
    The respective displacement device 21, 22 each comprise at least one hydraulic cylinder.
    The respective third attachment section 13a, 13b of the attachment 10 is coupled to ensure the displaceability thereof relative to the respective second attachment section 12a, 12b of the attachment 10 with the first attachment section 11 via a traction-transmitting element 23, namely such that at the by the respective displacement device 21st initiated displacement of the respective second header section 12a, 12b relative to the first header section 11 of the respective third header section 13a, 13b positively coupled to the displacement of the respective second header section 12a, 12b about the pivot axis 15a, 15b is displaceable. Details of this forced coupling will be further described.
    The displacement of the respective second attachment portion 12a, 12b of the attachment 10 and of the respective third attachment portion 13a, 13b of the attachment 10 is accordingly via the respective displacement device 21, which serves for the displacement of the respective second header portion 12a, 12b relative to the first header portion 11, and about the positive coupling of the respective third header section 13a, 13b to the first header section 11 via the respective traction-transmitting element 23. The respective traction-transmitting element 23 is preferably formed as a rope or alternatively as a chain.
    The respective traction-transmitting element 23 engages with a first end on the first header section 11 and with an opposite second end on the respective third header section 13a, 13b.
    The respective third attachment section 13a, 13b comprises a deflecting element 24 for the respective traction-transmitting element 23.
    The respective deflecting element 24 is an assembly of the respective third header section 13a, 13b.
    The respective traction-transmitting element 23 engages with its second end on the respective deflecting element 24 of the third header section 13a, 13b and is cast with the same in particular.
    At the respective transmission element 24, a portion of the traction-transmitting element 23 adjacent to the second end of the respective traction-transmitting element 23 is guided during the displacement of the respective third attachment section 13a, 13b relative to the respective second attachment section 12a, 12b such that during the displacement of the respective third attachment section 13a, 13b, relative to the respective second attachment section 12a, 12b, the respective tensile force-transmitting element 23 is more strongly wound with this section around the respective deflection element 24 or is unwound more strongly from the respective deflection element 24.
    If the attachment 10 is to be transferred, starting from the completely unfolded position shown in FIGS. 1 a, 1 b, in the direction of the fully folded position shown in FIGS. 4 a, 4 b, when the respective second attachment section 12 a, 12 b is folded in relative to the first attachment section 11 forcibly coupled and the respective third attachment portion 13a, 13b pivoted relative to the second attachment portion 12. In the case of this positively coupled displacement of the respective third attachment section 13a, 13b, the section of the respective traction-transmitting element 23 adjoining the second end of the respective traction-transmitting element 23 is wound more tightly around the respective deflection element 24 for the respective traction-transmitting element 24. In the reverse displacement of the respective third header section 13a, 13b relative to the respective second header section 12a, 12b, the respective traction-transmitting element 23, namely the adjacent to the second end of the same portion, more unwound from the respective deflection element 24.
    The respective deflection element 24 is rotatably mounted on the respective third attachment section 13a, 13b. A respective axis of rotation is preferably adjacent to the second end of the respective traction-transmitting element 23. The respective deflecting element 23 is supported on an eccentric 29, which is fixedly connected to the respective second header section 12a, 12b. The respective eccentric 29 moves the respective deflection element 24 about its axis of rotation on the respective third attachment section 13a, 13b up and down.
    The respective eccentric 29 ensures that the respective deflecting element 24 during folding its distance from the pivot axis 16a, 16b between the respective second header portion 12a, 12b and the respective third header portion 13a, 13b so far reduced that trained in a rope, traction transmitting Element 23 a cable vector always sufficient lever to the pivot axis 16a, 16b between the respective second header section 12a, 12b and the respective third header section 13a, 13b has. In the fully extended position of the respective eccentric 29 ensures a higher position of the respective deflecting element 24, so that the respective deflecting element 24 does not protrude below the agricultural implement or attachment and reduces the ground clearance of the same.
    The respective traction-transmitting element 23 engages with the first end in the embodiment shown on a lever mechanism 25 of the first header section 11.
    In this case, each lever mechanism 25 of the attachment 10 has a plurality of articulated links 26, 27 and 28.
    A first link 26 is pivotally attached to a first portion of the first header section 11 at a first end.
    A second link 27 engages with a first end articulated on a second portion of the first header section 11, preferably on the respective formed between the first header section 11 and the respective second header section 12a, 12b pivot axis 15a, 15b.
    Between the first link 26 and the second link 27, a third link 28 is positioned, which engages with a first end at the second end of the first link 26 with a second end at a second end of the second link 27 articulated.
    The respective traction-transmitting element 23 engages with its first end articulated at the second end of the second link 27 and thus at the second end of the third link 28 of the respective lever mechanism 25 at.
    Then, when the attachment 10, starting from the fully unfolded state of Fig. 1a, 1b is transferred to the partially folded state of Fig. 3a, 3b, in which case the respective traction transmitting element 23 permanently transmits tensile forces, the respective lever mechanism 25 is conditional held by the respective tensile force transmitting element 23 transmitted tensile forces in the alignment shown in Fig. 1a to 3b, in which the arms 26, 27 and 28 are aligned substantially L-shaped to each other. If the attachment 10 from the state of Fig. 3a, 3b in the direction of the state of Fig. 4a, 4b further collapsed, then transmits then following the state of Fig. 3, the respective tensile force transmitting element 23 no more tensile forces, so then 3a, 3b in the state of Fig. 4a, 4b can be displaced, so that then the already folded header sections on the first header section 11 can be stored to save space without collision with the respective lever mechanism 25. The first link 26 may be designed as an adjusting element, e.g. with thread and adjusting tube. Thus, the respective preferably designed as a rope, traction transmitting element 23 can be stretched.
    The positive coupling between the respective third header section 13a, 13b and the respective second header section 12a, 12b of the attachment 10 is made such that the respective third header section 13a, 13b can perform the entire pivoting range by the positive coupling, without an additional hydraulic cylinder.
    This positive coupling between the respective third attachment section 13a, 13b and the respective second attachment section 12a, 12b of the attachment 10 is taken exactly only in sections. Starting from the working position of the attachment 10, the respective second attachment section 12a, 12b is displaced by a first angle section of approximately 90 °, in which case the respective third attachment section 13a, 13b is already displaced by 180 ° and on a stop of the respective second attachment section 12a , 12b. During the further displacement of the respective second header section 12a, 12b, the respective third header section 13a, 13b then remains in contact with this stop.
