    Agricultural working tool
    The invention relates to an agricultural implement such as e.g. an attachment of an agricultural harvesting vehicle. Furthermore, the invention relates to a hat-like conveying element for an agricultural implement.
    Agricultural implements are known from the prior art, which have a first, middle and fixed implement section and a plurality of adjacent to both sides of the first implement section and the same displaceable second implement sections. 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 the center well and the adjoining, displaceable second implement sections also as the 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 respective second implement sections. The inner second working device sections can be displaced by a respective pivot axis relative to the first working device section, the outer second working device sections adjoining the inner second working implement sections opposite the first working implement section also being displaceable about pivot axes relative to the respective inner second working implement section. 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 second work implement sections adjoining the stationary, first work implement section 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, fixed implement section and adjacent to both sides of the first implement section second implement sections, which are each displaced, namely such that the inner second implement sections are displaceable to the first implement section each about a pivot axis, and that the outer second implement sections, which adjoin the first implement section to the respective inner second implement section, are each displaceable about a pivot axis relative to the respective inner second 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.
    It is known from the prior art that each working implement section of such an agricultural implement has cutting members and / or conveying members. Mowers are used for separating and conveying the crop, whereas the conveying organs are used exclusively for conveying already separated crop. In the transport position of the implement, the mowing members and / or conveying members of the implement portions that can be displaced relative to one another may not collide with one another. Therefore, the dimensions of the Mähorgane and / or conveying members to ensure a compact transport position are limited.
    There is a need for an agricultural implement which, on the one hand, allows improved conveyance of the crop to be separated or separated, and which, on the other hand, can still be converted into a compact transport position.
    Proceeding from this, the present invention seeks to provide a novel agricultural implement and a Hutartiges conveyor element for an agricultural implement.
    This object is achieved by an agricultural implement according to claim 1.
    According to the invention, a hat-shaped conveying element made of an elastically deformable material is positioned on at least one of the mowing members and / or on at least one of the conveying members of at least one working implement portion. The or each hat-like conveying element, which is each positioned on a mowing or conveying member, improves the promotion of the separated or separated crop within the agricultural implement. Characterized in that each hat-like conveying element is formed of an elastically deformable material, the same can deform in the transport position, so as to ensure a compact transport position of the implement.
    According to an advantageous embodiment of the invention, the or each hat-like conveying element, which is preferably made of an elastomeric material, elastically deformed in the transport position of the implement, wherein the same automatically returns in the working position of the implement in its initial shape or working form. This embodiment of the or each hat-like conveying element is to ensure a compact transport position and to ensure effective promotion of the crop in the working position of the implement particularly advantageous.
    According to an advantageous embodiment of the invention, the or each hat-like conveying element has a hutkrempenartigen section and a hat-crown-like portion, wherein the conveying element is supported with its hutkrempenartigen section on the respective mowing or the respective conveying member, and wherein the hat-crown-like portion of the conveying element is formed bellows. This embodiment of the or each hat-like conveying element is particularly preferred in order to ensure the automatic recoverability of the respective conveying element in its initial form or working form.
    The hat-like conveying element for an agricultural implement is defined in claim 10.

    Fig. 5 is a perspective view of a hat-like conveying element egg nes invention, designed as an attachment of an agricultural harvesting vehicle, agricultural implement; and
    6 shows a cross section through the hat-like conveyor element of FIG. 5.
    The invention is described below for an attachment designed 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, namely a first, fixed header section, and on both sides thereof via second, 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 second header portions are also referred to as a boom.
    Fig. 1 shows a header 10 for an agricultural harvesting vehicle, in Fig. 1, a first, fixed header section 11, adjacent to this first header section 11, relative to the first header section 11 movable inner second header sections 12a, 12b, to the inner second Attachment portions 12a, 12b opposite to the first header section 11 adjacent central second header sections 13a, 13b and to the middle second header sections 13a, 13b opposite to the respective inner second header section 12a, 12b adjacent outer second header sections 14a, 14b are shown.
    The inner second attachment sections 12a, 12b of the attachment 10 are displaceable relative to the first attachment section 11 by a respective pivot axis 15a, 15b. The middle second attachment sections 13a, 13b of the attachment 10 are displaceable relative to the respective inner second attachment section 12a, 12b about a pivot axis 16a, 16b. The outer second attachment sections 14a, 14b of the attachment 10 are displaceable relative to the respective middle second attachment section 13a, 13b about a pivot axis 17a, 17b.
    In the exemplary 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 a conveying member 20 carries.
    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 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 header sections 12b, 13b and 14b positioned to an opposite second side of the first header section 11 have, with respect to the first header section 11 , Symmetrical support members 18 for the Mähorgane 19 and / or the conveying members 20 on.
    The support elements 18 of the second attachment sections 12a, 13a, 14a, 12b, 13b, 14b positioned on both sides of the first 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. In the working position, all supporting elements 18 of all attachment sections 11, 12a, 13a, 14a, 12b, 13b, 14b are arranged side by side in one layer.
    In the exemplary embodiment, for transferring the implement 10 between the transport position and the working position, the inner second attachment sections 12a, 12b relative to the first, fixed implement section 11 about the pivot axes 15a, 15b each pivotable through 180 °. The middle second header sections 13a, 13b are also pivotable by 180 ° relative to the respective inner second header section 12a, 12b about the respective pivot axes 16a, 16b. The outer second header sections 14a, 14b are each pivotable by 150 ° to 170 ° relative to the respective central second header section 13a, 13b. This ensures that the support elements 18 of the first header section 11 and the inner second and middle second header sections 12a, 13a, 12b, 13b in the transport position parallel to each other, whereas the support members 18 of the outer second header sections 14a, 14b in the transport position obtuse each other run. 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.
    The support element 18 of the first header section 11 accommodates four mowing members 19 and four conveying members 20. The support elements 18 of the inner second header sections 12a and 12b respectively receive two mowing members 19 and one conveying member 20 each. The support elements 18 of the middle second attachment sections 13a, 13b each receive two mowing members 19 and two conveying members 20 each. The support elements 18 of the outer second header sections 14a and 14b each receive a mower 19.
    Here, the mowing members 19 assigned to the outer second attachment sections 14a and 14b have larger diameters than the mowing devices 19 assigned to the other attachment sections 11, 12a, 12b, 13a, 13b. The above number and division of the mowing devices 10 and conveying elements 20 onto the attachment sections 11, 12a, 12b, 13a, 13b, 14a, 14b is exemplary in nature. Thus, the center trough or the first header section 11 may also have only two mowing members 20.
    In order to displace the implement 10 from the unfolded working position into the folded transport position, the second attachment sections 12a, 13a, 14a positioned to the first side of the first attachment section 11 are synchronous with the second attachment sections 12b positioned to the second side of the first attachment section 11, 13b, 14b relocated. In this case, it is possible to proceed in such a way that during a displacement, starting from the working position into the transport position, the outer second working device sections 14a, 14b are displaced first, followed by the inner and middle second working device sections 12a, 13a, 12b, 13b relative to the first working device section 11 be relocated. In the reverse shift from the transport position to the working position then first the inner and middle second implement sections 12a, 13a, 12b, 13b and only then the outer second implement sections 14a, 14b displaced.
    The inner 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. The outer second attachment sections 14a, 14b are displaceable relative to the middle second attachment sections 13a, 13b about the pivot axes 17a, 17b by means of a respective further displacement device 22. De respective displacement device 21,22 each comprises at least one hydraulic cylinder. The respective middle second attachment portion 13a, 13b of the attachment 10 is coupled to ensure the displaceability of the same relative to the respective inner second header portion 12a, 12b of the attachment 10 with the first header portion 11 via a traction transmitting element 23, namely such that in which by the respective Displacement device 21 initiated displacement of the respective inner second header section 12a, 12b relative to the first header section 11 of the respective central second header section 13a, 13b positively coupled to the displacement of the respective inner second header section 12a, 12b about the pivot axis 15a, 15b is displaced. The displacement of the respective inner second attachment section 12a, 12b of the attachment 10 and of the respective middle second attachment section 13a, 13b of the attachment 10 is thus effected via the respective displacement device 21, which serves for the displacement of the respective inner second attachment section 12a, 12b relative to the first attachment section 11 , as well as via the positive coupling of the respective middle second attachment section 13a, 13b to the first attachment section 11 via the respective traction-transmitting element 23.
    The respective traction-transmitting element 23 is preferably designed 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 central second header section 13a, 13b. The respective middle second attachment section 13a, 13b comprises a deflection element 24 for the respective traction-transmitting element 23. The respective deflection element 24 is an assembly of the respective central second attachment section 13a, 13b. The respective traction-transmitting element 23 engages with its second end on the respective deflection element 24 of the middle second attachment section 13a, 13b and is encapsulated therewith 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 middle second attachment section 13a, 13b relative to the respective inner second attachment section 12a, 12b such that during the displacement of the respective one Middle second header portion 13a, 13b relative to the respective inner second header portion 12a, 12b, the respective tensile force transmitting member 23 is wound more strongly with this portion around the respective deflecting element 24 or more unwound from the respective deflecting element 24.
    If the attachment 10 is to be transferred starting from the completely unfolded position in the direction of the fully retracted position, the respective middle second attachment portion 13a, 13b is forcibly coupled relative to the first attachment portion 11 when the respective inner second attachment portion 12a, 12b is relative to the inner second attachment portion 12 pivoted. In the case of this positively coupled displacement of the respective middle second 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 middle second header section 13a, 13b relative to the respective inner second header section 12a, 12b, the respective tensile force 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 middle second 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 inner second header section 12a, 12b. The respective eccentric 29 moves the respective deflecting element 24 up and down about its axis of rotation on the respective middle second attachment section 13a, 13b. The respective eccentric 29 ensures that the respective deflection element 24 during folding its distance from the pivot axis 16a, 16b between the respective inner second header portion 12a, 12b and the respective middle second header portion 13a, 13b so far reduced that when trained as a rope , tensile force transmitting element 23 a cable vector always sufficient lever to the pivot axis 16a, 16b between the respective inner second header portion 12a, 12b and the respective middle second header portion 13a, 13b has. In the fully extended position, the respective eccentric 29 ensures a higher position of the respective deflecting element 24, so that the deflecting element 24 does not protrude below the agricultural implement and reduces the ground clearance thereof.
    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 articulates with a first end to a second portion of the first header section 11, preferably to the respective pivot axis 15a, 15b formed between the first header section 11 and the respective inner second header section 12a, 12b. 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.
    The positive coupling between the respective middle second header section 13a, 13b and the respective inner second header section 12a, 12b of the attachment 10 is made such that the respective central 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 middle second header section 13a, 13b and the respective inner second header section 12a, 12b of the attachment 10 takes place only in sections. Starting from the working position of the attachment 10, the respective inner second attachment portion 12a, 12b is displaced by a first angle portion of approximately 90 °, in which case the respective middle second attachment portion 13a, 13b is already displaced by 180 ° and at a stop of the respective inner second header portion 12a, 12b abuts. During the further displacement of the respective inner second attachment section 12a, 12b, the respective middle second attachment section 13a, 13b then remains in contact with this stop.
    In the pivot axes 15a and 16a and 15b and 16b opposite pivotal movements are performed. Likewise, opposing pivotal movements are performed in the pivot axes 16a and 17a or 16b and 17b. The pivoting movements in the pivot axes 15a and 17a or 15b and 17b are then the same direction.
    It should be noted at this point that the above-described embodiment of the implement 10 with the first implement portion 11 and arranged on both sides thereof, three second implement portions 12a, 13a, 14a and 12b, 13b, 14b and the displacement of the implement sections to each other Although preferred via the displacement devices 21, 22 and the traction-transmitting elements 23 and the lifting mechanisms 25, it is not mandatory for the invention. Rather, the invention can also be used in agricultural implements, which have a different number of implement sections, as well as work implements, the implement section are moved in a different manner relative to each other.
    According to the invention, at least one of the mowing members 19 and / or at least one of the conveying members 20 of at least one implement portion 11, 12a, 12b, 13a, 13b, 14a, 14b positions a hat-shaped conveying element 30 made of an elastically deformable material. In the embodiment of FIG. 2, such a hat-like conveying element 20 is positioned on the mowing member 19 of the respective outer, second implement section 14a, 14b. In the exemplary embodiment of FIGS. 3 and 4, such a hat-shaped conveying element 30 is arranged on a conveying member 20 of the respective middle second working implement section 13a, 13b.
    The hat-like conveying elements 30 are formed from an elastically deformable material, preferably made of an elastomeric material, such as a rubber-like material or rubber.
    As can be seen in FIGS. 2 and 4, the respective hat-like conveying element is elastically deformed in a transport position of the implement, with the same automatically returning to its starting shape and working form in the working position of the implement 10.
    The hat-like conveying elements extend the overall height of the respective mower 19 or conveyor member 20 in the vertical direction, so that in the working position of the implement 10 to be separated or separated crop better transported within the implement 10 and thus promoted. Due to the fact that the respective hat-shaped conveying element 30 deforms in the transport position, the dimension of the working device in the transport position is not increased by the hat-like conveying elements 30, so that a compact dimension of the working device in the transport position thereof can still be ensured.
    5 and 6 show a hat-like conveying element 30 in greater detail, the respective hat-like conveying element 30 having a hat-brim-like section 31 and a hat-crown-like section 32.
    The respective conveying element 30 is supported by its hat-brim-like section 31 on the respective cutting member 19 or the respective conveying member 20. The hat-crown-like portion 32 protrudes upward, wherein the hat-crown-like portion 32 of the respective conveying member 30 is formed bellows-like. A circumferentially extending or circumferential circumferential side wall 30 of the cap-crown-like portion 32 of the respective hat-like conveying element 30 has a corrugated contour in cross-section.
    In the preferred exemplary embodiment shown, cusp tips 34 are formed on the corrugated contour of the circumferential circumferential side wall 33, wherein the straight lines 35 which run through the cusp tips 34 of the selected contour of the circumferential side wall 33, in the direction of an end facing away from the brunt-like portion 31 of the hat-crowned portion 32 converge. As a result, the hat-shaped conveying elements 30 are particularly advantageous elastically deformable and automatically returned from the deformed shape to its original shape.
    The conveying element 30 may comprise return means, such as e.g. Springs are attributed, which support the return to the original form or apply the restoring force almost completely alone. This can be advantageously ensured that a conveyor element 30 is fully upright again when the implement 10 is brought into working position. As a return means, for example, a helical spring can be provided, which is arranged in an inner cavity of the conveying element 30.
