    15 20 25 30 and folded away, respectively, to move the filling device to an inactive position, preferably located near the machine body.
    To prevent seed or fertilizer present in the pipe from falling out when the lower pipe section is swung away at the dividing point, the dividing point or the open pipe end can be closed with a lid. The filling line is usually designed as a riser or more or less inclined towards the horizontal plane, in order to be able to guide the seed upwards into the machine magazine from a lower hopper. Should the hopper with the lower part of the filling line be simply moved away without resealing the lower end of the upper pipe part thus opened, seeds located in the upper part of the filling line would drain out during use by shaking and vibration.
    Apart from this loss of seed, it is also a matter of soiling the interior of the pipe, which soiling is then led into the magazine when the feeding means are put back into operation.
    When closing the dividing point by means of a lid, when the feed hopper is folded down, the problem sometimes arises that the lid unintentionally comes loose again, when it is not properly fastened or when the lid is completely forgotten. Conversely, when re-attaching or connecting the dividing point, the lid may not be removed in a timely manner, whereby the auger arranged in the interior of the filling line can be damaged, which entails partly costly repair work.
    The object of the present invention is to create an improved agricultural machine of the kind mentioned in the introduction, which avoids the disadvantages of the prior art and advantageously further develops it. In particular, the closure of the dividing point of the filling line must be simplified for the user of the machine and manure and seed losses and soiling of the interior of the line must be safely avoided.
    According to the invention, this object is solved by an agricultural machine according to claim 1. Preferred embodiments of the invention are subject to the dependent claims.
    It is thus proposed to provide the closure for closing the dividing site with an automatic operation, which closes the filling line end in the area of the dividing point, when said dividing point is divided and a part of the filling line is removed, and conversely the filling line ends reopen when the filling line ends put on top of each other again. According to the invention, adjusting means are arranged for automatic closing and / or automatic opening of the closure depending on the position of the removable pipe part. The adjusting means operate depending on the position and / or the movement of the removable pipe part, so that during removal the closure is applied or closed and when the removable pipe part is fastened, the closure is opened. This ensures on the one hand that when the filling device is in its inactive position, no seed or fertilizer sprinkles out of the open filling line or, conversely, that dirt cannot reach the interior of the line. On the other hand, damage to the closure and to the feed means in the interior of the filling line is avoided, when the filling device is moved from the inactive position to the active position and the filling line parts are put on top of each other.
    Said adjusting means can hereby be in principle differently designed. For example, a sensory registration of the position and / or the movement of the remotely operable filling device part may be arranged and a scar-actuated actuator be arranged, which is controlled depending on a sensor signal from a control means, to actuate the actuator and thus the closure in said manner depending on the position of the removable filling device part. However, in an advantageous further development of the invention, the adjusting means for automatically closing and / or opening the closure may comprise a mechanical coupling of the closure to the removable filling device part, the mechanical coupling converting a movement of the removable filling device part into an adjusting movement of the closure. such as for the closure in a closing position when the filling device part is actuated away in the inactive position and for the closure in its open position when operating the filling device part in the active, engaged position of the closure.
    The mechanical coupling connected to the closure can hereby be linked to different sections of the removably operable filling device part, whereby for instance by a reptile mechanism the adjusting movement of the closure can also be diverted from distant filling device parts such as the filling funnel. at the sharing point.
    According to a preferred further development of the invention, however, the mechanical coupling is linked to the removable closure, near the dividing point on the removable pipe section, which leads from the discharge opening to the dividing point, the linking of the mechanical coupling on the pipe section being arranged of the sharing point.
    In this way, a compact design of the adjusting means with short paths for the power flow can be achieved.
    Depending on the design of the dividing point and the kinematic device of the filling device part which can be carried in the inactive position, the setting means can be of different types. According to an advantageous further development of the invention, the feed opening, which may be formed by a hopper, can be pivoted away uniaxially or axially with a part of the filling line attached thereto through the aforementioned dividing point. The maneuverable pipe part can hereby be pivotally mounted about at least one pipe pivot axis, which runs transversely to the longitudinal direction of the filling pipe, in such a way that the pipe part is pivotable and maneuverable from the second pipe part by pivoting and by reverse pivoting can be connected to the second pipe part. Depending on the location available on the machine and on the pivoting movement generated to the inactive position, the pivotability may possibly be of multi-axis design, whereby several links in the form of a multipole drive unit can be arranged. According to an advantageous further development of the invention, however, the maneuverable pipe part can be connected to the other pipe part by only one pipe pivot shaft, so that the two pipe parts can be divided and reconnected by uniaxial pivoting relative to each other. The line pivot axis can thus advantageously extend outside or immediately on the wall of the filling line across the longitudinal extent. In particular, the cable pivot shaft can be arranged so that the two cable parts are collapsible on each other. The connection can also be mounted in different ways on one of the pipe sections, the closure advantageously also being uniaxially or multi-axis mounted on one of the pipe sections, in particular on the pipe section to be closed.
    Depending on the kinematics generated, a link device for controlling the closing movement can also be arranged, so that the closing can be maneuvered away along a controlled path of movement to and from the dividing point.
    According to an advantageous further development of the invention, the closure is connected to the pipe part which is to be closed by only one pivot shaft, so that the closure can be pivoted on the open end or pivoted away from it like a folding lid. According to an advantageous further development of the invention, the sealing pivot axis extends transversely to the longitudinal direction of the filling line, wherein the sealing pivot axis can be arranged outside the filling line and / or in the area of the walls of the respective pipe parts.
    In order to close the pivotally mounted closure, a link in particular can be provided, which on the one hand is hingedly connected to the removable cable part and on the other hand is hingedly connected to the closure.
    According to an advantageous further development of the invention, the line pivot axis and the closing pivot axis are oriented parallel relative to each other and / or arranged on opposite sides of the filling line. By means of an opposite arrangement of the two pivot shafts, the maneuverable cable part can be pivoted away to one side, while the closure can be pivoted away to the opposite side. As a result, a small collision potential arises between the closure and the maneuverable pipe section. Despite simple kinematics with only one pivot axis each for the maneuverable pipe section on the one hand and the closure on the other hand, this can ensure that the closure can be pivoted away on the right side in the open position, before the pipe section to be folded blocks the opening path of the closure. when the conductor parts are swung together.
    According to an advantageous further development of the invention, the pipe pivot axis, around which the maneuverable pipe part is pivotable to the second pipe part, can at least be arranged approximately in the dividing plane 10 between the two pipe parts. In this way an even frontal position of the pipe parts in relation to each other is achieved and the tendency to stiffen and displace is reduced. Alternatively or in addition to such a device of the conductor pivot axis in the pitch plane, the closure pivot axis may be arranged at a distance from the pitch plane.
    In particular, the closure pivot shaft can be arranged on the conduit part to be closed in such a way that it is spaced from its end section which forms the dividing point, the closure may comprise a lid part and a bearing part approximately rectangularly bent, which connects the lid to the spaced pivot shaft. .
    The mechanical coupling of the closure with the removable pipe part consists in a further development of the invention of only one guide arm, in particular in the form of a sliding support element, which on the one hand is hinged to the removable pipe section and on the other hand is hinged to the closure. . In principle, it would also be possible as a coupling to connect a rotary lever torsionally rigidly to the closure and, for example, to maneuver the remotely maneuverable cable part through a connecting link.
    Preferably, however, for operating the closure, only a pull / pressure element is provided, for example in the form of a rod, which is connected at a distance from the manoeuvrable pipe part and the closure. By skilful selection of the lowering points, the movement of the closure can thus be controlled and synchronized with the removable pipe part, so that a collision of the closure with the removable pipe section is prevented and still a secure closure of the other pipe section is achieved.
    According to an advantageous further development of the invention, the link point for the sliding / pulling element can be arranged on the removable pipe part, preferably in the area of the dividing plane and / or immediate proximity to the open end of the removable pipe part. Alternatively or in addition, the sliding / pulling element can be linked to the closure in the area with its connecting piece, which connects the lid part to the closure pivot shaft.
    In order to achieve on the one hand a tight closure of the open pipe end, when the corresponding filling device is moved in the inactive position, and on the other hand to compensate for changes in the kinematics of the remotely maneuverable filling device part, according to a further development of the invention the mechanical coupling be elastically designed and / or comprise elastic clamping means, by means of which the closure can be clamped in the closed position when the filling device part is fully actuated.
    Through such elastic tensioning means a sufficient closing force can be ensured. Incidentally, inaccuracies in removing the filling device part can also be compensated, so that it does not play a decisive role if the feeding funnel with the line part attached thereto is operated away a bit longer or a bit shorter in the inactive position.
    In particular, in an advantageous further development of the invention it can be arranged that the pushing / pulling element is designed to be changed in length and comprises a spring device for biasing the pushing / pulling element in an output length. During the opening and closing movement of the closure, the sliding / pulling element remains in the exit length. Only then, when the closure reaches its closing position and the removable cable part is further removed, does the sliding / pulling element undergo a change in length, which on the one hand enables the complete removal of the removable pipe part and on the other hand causes a bias and a sufficient closing force of the closure.
    In order to be able to compensate for mounting tolerances or wear, it is arranged in an advantageous further development of the invention that the sliding-pulling element comprises presetting means for presetting the length and the initial position of the sliding-pulling element, respectively.
    As a result, the secure closure of the dividing point can be set by simply adjusting the initial position of the sliding / pulling element. The present invention is explained in more detail below with the aid of a preferred embodiment and accompanying drawings. The drawings show: Fig. 1, a schematic side view of an agricultural machine in the form of a seed drill according to an advantageous embodiment of the invention, the magazine for storing the seed being shown on a machine frame above tillage tools, Fig. 2, a perspective partial view of the seed drill according to fig. 1, wherein the seed hopper and a filling device for filling the seed hopper comprising a lower down funnel, which is connected by a feed auger and a riser to the hopper, are shown in the active filling rack, Fig. 3, a perspective partial view of the filling device in Fig. 2. , which shows the filling line provided with a dividing point and interruptively designed in the filling position and the closure arranged for the dividing position in the open position, Fig. 4, a side view of the filling line in Fig. 3, which shows the closure in the open position and the sliding / pulling element for connection of the removable cable section with a lock Fig. 5, a side view of the filling line in Fig. 4 when pivoting the feed hopper, Fig. 6, a side view of the filling line in the preceding figures in the fully disengaged, inactive position, in which the closure closes the filling line and the filling line part, a sectional view of the sliding / pulling element for coupling the closure with the removable cable part, showing the length adjusting device and the clamping means of the sliding / pulling element.
    The seed drill 1 shown in the figures can be designed as a superstructure machine, which is mounted on a tractor 2 and comprises a machine frame 3, on which various tillage tools 4 can be attached, for example in the form of car discs, cultivator sticks and / or a ground pressure roller, to prepare the ground for spreading seed or fertilizer. The machine frame 3 carries a magazine 5, in which the seed, or even manure, can be stored. By means of a known distribution device, the goods which are spread out of the goods magazine 5 can be distributed, for instance by means of distribution hoses 7 to a row of spreading elements 6 arranged next to each other, transversely to the direction of travel.
    In principle, the seed magazine 5 can be filled from above, for example from a silo via the filling opening arranged on the top.
    In order to also be able to fill seed or manure in the goods magazine 5 from below, for example manually from sacks and / or in the field during refilling, a filling device 8 is connected to the goods magazine 5, as shown in Fig. 2. The filling device 8 hereby comprises a further down feed hopper 9, which can be filled through a feed opening 10 and is connected to the seed hopper 5 through a filling line 11.
    The hopper 9 is located in the active filling position shown in Fig. 2 below the seed hopper 5, preferably at a working height which is pleasant for the machine operator, for example stomach or hip height. The filling line 11 is designed as a riser and runs from the hopper 9 obliquely to the horizontal plane rising towards the seed hopper 5. In order to feed the goods to be filled from the hopper 9 upwards into the seed hopper despite the rise of the hopper line 11, one acts along the filling line. supply device 12, which in principle can be of different types, for example it can comprise a compressed air blowing device. In particular, the feeding device 12 may comprise a feeding auger 13 in the interior of the filling line 11, by means of which the goods can be fed from the feeding funnel 9 through the filling line 11 upwards into the seed magazine 5.
    The filling line 11 is provided in a central portion between the hopper 9 and the seed hopper 5 with a dividing point 13, at which the filling line 11 can be broken off, in order to be able to fold away the lower pipe part 11a together with the hopper 9 attached thereto, to be able to move the filling device 8 from the active position shown in Fig. 2 to a less projecting and less collision-prone inactive position preferably near the body of the seed drill 1. In particular, the filling line 11 can be divided approximately in the middle, so that the lower half can be pivoted away, especially upwards over the upper half, whereby the length of the filling device 8 is halved. The filling line 11 can run arcuately. When using the auger, however, the filling line 11 preferably runs straight, as Fig. 3 shows.
    At the dividing point 13 of the filling line 11, a hinge 14 is arranged, by means of which the upper and the lower line parts 11a and 11b are pivotally connected to each other. The thread 14 provides a conductor pivot shaft 15 which extends transversely to the longitudinal direction of the filling conduit 11 outside the filling conduit, cf. Figs. 3 and 4, wherein it may be arranged in particular that the conductor pivot shaft 15 extends on the top of the filling conduit 11 in the horizontal direction. the lower conduit portion 11a can be pivoted away upwardly over the upper conduit portion 11b.
    The removal of the removable line part 11a as well as the feed hopper 9 mounted thereon can in principle take place manually, whereby preferably also a pivot drive device 16 can be arranged, which is associated with the line pivot shaft 15 and the two line parts can pivot relative to each other about the shaft. For example, the pivot drive device 16 may be a spindle drive device or the pressure medium cylinder shown in Fig. 3.
    In order to be able to separate the line parts 11a and 11b at the dividing point 13, the drive screw in the interior of the filling line 11 in the area of the dividing point 13 may comprise a coupling and correspondingly be two-part or even, depending on the design of the filling line 11, stop at the dividing point 13.
    As shown in Figures 5 and 6, the dividing point 13 opens upon pivoting of the lower conduit portion 11a, so that two open conduit ends are formed. The conduit end of the upper conduit part 11b can hereby be closed by a closure 17, in order to prevent seed or manure from spreading outwards out of the steep upper conduit part 11b.
    As shown in Figures 4 to 6, the closure 17 comprises a substantially flat lid part 18, the contour of which is so far adapted to the opening cross-section of the pipe part 11b that the lid part 18 can completely close the open pipe end, preferably it can be pressed substantially evenly against the edge of the open pipe end. The lid part 18 is pivotally connected to the conduit part 11b to be closed by a rigidly connected link piece 19, which extends substantially transversely to the plane of the lid part 18, the link piece 19 extending from the open end cross section of the pipe part 11b a distance along the pipe outer side, compare Fig. 6, the proximity closure 17 is closed. The link piece 19 forms part of a hinge 20, with which the closure 17 is linked and mounted on the pipe part 11b to be closed. The sealing pivot axis 21 extends at a distance from the end of the conduit part 11b substantially transversely to its longitudinal direction on the outside of the wall, cf. Figs. 4-6.
    The adjusting means 22 for automatic closing and opening of the closure 17 comprise in the illustrated embodiment a mechanical coupling 22, which may in particular comprise a link in the form of a sliding / pulling element 23, which on the one hand is hinged to the closure 17 and on the other hand on the removable pipe part 11a, the link points 24 and 25 on the closure 17 and on the removable pipe part 11b respectively allowing at least one pivotability about axes parallel to the pipe pivot shaft 15 and the closing pivot shaft 21, respectively.
    As Fig. 5 shows, the line pivot shaft 15 and the closing pivot shaft 21 are arranged on opposite sides of the filling line 11 and extend parallel to each other.
    The link point 25 of the sliding / pulling element 23 on the operable line part 11b is located in such a way that in the connected position of the two line parts 11a and 11b according to Fig. 4, in particular the link piece 19 of the link point 25 extends substantially on a straight connecting line between the lead pivot shaft 15 and the closure 17.
    The link point 24 of the sliding / pulling element 23 located on the closing side is thus mounted on the link piece 19, in particular in such a way that the sliding / pulling element 23 over the entire pivot path of the closure 17 has a lever relative to the closing pivot shaft 21 and that no closing 17 happens to be in a deadlock.
    As Fig. 4 shows, the link points 24 and 25 and the conduit pivot axis 15 as well as the closure pivot axis 21 are arranged relative to each other in such a way that in the assembled active position of the conduit parts 11a and 11b the closure 17 extends completely outside the contour of the filling conduit. 11. Only when the removable pipe part 11b is pivoted away a distance, as shown in Fig. 5, does the contour of the lid part 18 of the closure 17 dive into the contour area and the dividing section between the pipe parts 11a and 11b, respectively. If the maneuverable pipe part 11b is swung away to its completely swiveled position, the sliding / pulling element 23 swings the closure 17 further further, until finally the fully closed position shown in Fig. 6 is reached. In addition, if the conduit part 11b is further folded down, an extension of the sliding / pulling element 23 follows, whereby a corresponding closing force of the lid part 18 is achieved towards the front of the conduit part 11b to be closed.
    As Fig. 7 shows, the sliding / pulling element 23 can for this purpose be designed to be length-adjustable, in particular in the form of an elastic length-adjustable spring leg.
    In addition, the pushing / pulling element 23 comprises two relatively slidably mounted sections, which can in particular be slidable in each other and telescopically in each other like a telescope. By means of a prestressing device 26, which may preferably comprise a spring device 27, the pushing / pulling element 23 can be prestressed in a starting position. Preferably, the spring device 27 is hereby accommodated in the interior of the pushing / pulling element 23.
    The output length of the sliding / pulling element 23 is hereby preferably adjustable. A corresponding presetting device 28 may, for example, comprise an adjustable stop in the form of an adjusting screw 29.
