    Agricultural machine.
    The present invention relates to an agricultural machine with a metering roller for transporting harvested goods through a transport channel to a well-collecting chamber, wherein the metering roller comprises forward-facing troughs on a circumferential side which extend over the width of the metering roller along a profile course distributed.
    Such agricultural machines can, for example, be designed as a loading wagon or baling press, wherein the said metering roller can be equipped with a good pick-up, for example in the form of a pick-up or a spine roller, in order to be able to receive lying, halm and / or leaf-shaped harvested goods . The harvested goods taken up by the hopper are fed further through the dosing roller through the transport channel and get into a well-receiving room, which can be a bale forming chamber when the machine is executed as a baler and, when the machine is executed as a loading wagon, the storage of the loading wagon. Depending on the embodiment of the machine, the metering roller can, however, also transfer the goods to other processing units, for example to cross conveyors or conditioning tools for conditioning the harvested material.
    Optionally, the said metering roller can be provided with a cutting device, which usually comprises a plurality of cutting blades extending into the transport channel, such that harvesting material fed through the transport channel is cut from the metering roller.
    In the case of such machines it may hitherto lead to the fact that the crop material swath to be picked up is clearly narrower if the width of the metering rollers or the transport channel or in a central part has clearly more volume than to the edges, such that the crop material is not evenly distributed over the The width of the transport channel is divided when it is passed through the dosing roller through the said transport channel. Due to such an uneven distribution of the crop over the width of the transport aggregate, on the one hand the performance capacity of the transport aggregate cannot be utilized, because the transport speed must be adjusted to the swath volume in a central area, while in peripheral areas the possible transport capacity is not utilized, or it leads to blockages or interruptions due to too large transport volumes, in particular when a cutting operation is used. Furthermore, the uneven distribution of crop material for the filling of the subsequent good receiving chamber is critical. With balers it leads to unevenly shaped bales, while with loading wagons the possible loading volume of the storage chamber is not utilized.
    Publication DE 10.2004.061.678 B4 discloses a dosing roller for such an agricultural machine, wherein the conveyor strips can be rotated in circumferential direction and fixed at different positions, such that different profile courses of the rotor section arrangement can be set. In particular, neighboring rotor sets can be adjusted a lot further relative to each other in circumferential direction, such that neighboring rotor sets run after each other. The rotor tips of rotor sets arranged next to each other herein define a profile line which, depending on rotation of the rotor sets, extends more or less obliquely in the direction of the rotary axis of rotation, which means that the rotor sets are arranged according to a screw or define a helical profile profile.
    The aforementioned publication states that an arrow-shaped profile course of the prong arrangement is adjustable, such that a narrow crop material swath can be distributed over the width of the metering roller. For adjusting such an arrow-shaped conveyor arrangement, the rotatable conveyor belts are connected together by two operating rods, which are coupled on the one hand to the outermost conveyor belts and, on the other hand, are coupled to a centrally located conveyor, so that when rotating the in the central transport plant the outward connecting transport plant is always taken along a lot less and always take a smaller off-set in the circumferential direction.
    Although such an arrow-shaped profile development of the conveyor arrangement moderates the problems described above and can distribute an excessively centered crop swath, it leads, in particular with wider crop swaths, to an excessive pushing out of the feed mat and to increased lateral friction on the side walls of the conveyor belt. good collection chamber and the transport channel set up for that purpose. In addition, in conjunction with cutting operations, cyclically increasing and decreasing or changing rotational resistance of the metering roller, depending on the rotational position of the metering roller, leads to the extent to which many rotor-series cutting blades end up or pass this, because in the case of multi-row metering rollers, means metering rollers with a plurality of conveyor rows means that the arrowheads of a trailing row of rows are already ready for engagement with the knives before the lateral edges of the forwardly extending conveyor rows have completely passed the cutting blades.
    The invention has for its object to provide an improved agricultural machine of the above-mentioned type which avoids disadvantages of the prior art. In particular, an improved transverse distribution of the crop material with an even circumference of the metering roller will be achieved.
    According to the invention, the said object is achieved by an agricultural machine according to claim 1. Preferred embodiments of the invention are subject to the dependent claims.
    Furthermore, it is also proposed that the profile profile of the conveyor arrangement is not simply divided into two uniformly inclined profile sections, such as with an arrow arrangement, but to rejuvenate the profile profile multiple times within itself. The slope of the profile gradient is also changed within a profile section. According to the invention, the profile profile defined by the adjacent conveyor strips starting from a central portion of the metering roller has two oppositely oriented profile sections that run obliquely in the direction of the rotary axis of rotation, the angle of inclination of which changes towards an edge portion of the metering roller. As a result, a different transverse conveying effect can be achieved in the edge portion of the dosing roller as in the middle portion of the dosing roller. In particular, a transverse conveying action can be provided in the middle portion of the metering roller outwards to the edge portions, which can be omitted towards the edge portions or vice versa, such that a pulling apart of the crop carpet uniformly in the middle portion and a reduction of the swath volume in the center and, on the other hand, over-pressing of the crop in the peripheral area can be avoided.
    The slope of the profile profile can at least decrease from the central part to the edge parts of the metering roller and / or go to zero and / or be reversed, such that a transverse conveying action on the harvested material running opposite to the middle part is effected in the peripheral parts.
    In a further embodiment according to the invention, each of said profile sections, which are oppositely oriented from the center of the metering roller, may comprise a reverse twist towards each edge sections of the metering roller, such that each profile section is two oppositely oriented, towards the rotor axis direction includes oppositely extending obliquely extending lower portions.
    In particular, the lower portions of the profile course adjacent to the center portion of the metering roller can be oriented with respect to the direction of rotation such that the crop from the center portion experiences a transverse conveying action to the outside, that is, from the center portion apart to the edge portions. while the lower parts adjacent to the edge portions of the metering roller can be oriented with respect to the rotational direction of rotation such that the crop in the edge portions of the metering roller experiences a transverse conveying action directed away from the edge portion towards the center portion.
    Seen from the middle part of the metering roller, a row of conveyors is also screwed to the relevant edge part in a first direction and then screwed to an edge part in the opposite direction. The screw or the twist turns towards the edge portion.
    In a further embodiment according to the invention, the lower parts of the aforementioned profile parts oriented towards the middle part can together have a greater width than the lower parts oriented towards the edge parts with the reverse twist. Viewed as a whole, the harvested material is pulled apart over a larger part of the metering roller width and only moved back towards the center in smaller edge sections. For example, the lower portions oriented toward the center portion together may make up about two thirds and the outward, inverted lower portions make up about one third of the total metering roll width.
    The transition from the profile course to the outer section or the area of the profile course in which the twist reversal takes place can be harmonic and rounded, or also continuous according to an arrowhead.
    In order to achieve a smooth running of the metering roller with little rotational resistance pulsation and to keep the number of conveyor belts located with the cutting unit in engagement as evenly as possible, a further embodiment according to the invention can provide that the opposing oblique profile sections of the profile course on an intermediate portion of the metering roller include an offset with respect to each other in the circumferential direction of the metering roller. The profile guide lines of a right and a left profile section defined by the tops of the conveyor strips also do not coincide in the center of the metering roller according to an arrow point, but run from different circumferential points of the metering roller center, which are angled towards each other in circumferential direction staggered. Advantageously, said offset can be approximately half of the distribution angle at an angle on the central part, which angle is defined by the distance between two rows of conveyors moving forward and backward in the same profile section in the circumferential direction. When the metering roller has, for example, four conveyor rows distributed over the circumference, the said distribution angle is 90 °, such that the offset over the circumference of the profile section on a central section of the metering roller can be 45 °. The profile row of a, for example, straight dosing roller half also runs away in the center of the dosing roller from circumferential points which, viewed in the circumferential direction, lie approximately in the middle between the conveyor rows of the left-hand dosing roller half.
    In an advantageous further embodiment according to the invention, the metering roller is designed as a overhead conveyor, wherein the transport channel through which the metering roller carries the harvested goods extends over the metering roller above the metering roller. In the case of such overhead rollers, the described oblique profile course of the conveying arrangement can show its transverse conveying effect particularly efficiently.
    In a further embodiment according to the invention, the metering roller can be provided with a cutting device, whose cutting blades extend as far as into the conveying channel or extend as far as the metering roller, such that the conveyor belts projecting beyond the knives harvest the crop against the cutting blades. to cut.
    The cutting blades can be arranged along a straight profile line, which can extend parallel to the rotational axis of rotation.
    The profile course of the conveyor rows described above and the staggering between the profile parts on the central part of the metering roller is in particular designed such that, viewed over a full circumference of the metering roller, approximately the same knife number engages or cooperates with each other. The conveyor belts are also offset over the width of the metering roller relative to each other in such a circumferential direction that approximately the same number of conveyor belts are in engagement with the cutting blades. Hereby torque peaks can be avoided and a rounder roll run can be obtained.
    The invention is explained in more detail below with reference to exemplary embodiments according to a preferred embodiment and associated drawings. Show in the drawings:
    FIG. 1: a front perspective view of a dosing roller of an agricultural machine according to an advantageous embodiment according to the invention, wherein the respective obliquely arranged profile sections of the profile course of the conveyor rows are shown, and
    FIG. 2: a front view in perspective according to a section of the agricultural machine, which shows the installation condition of the dosing roller from FIG. 1 and the pick-up drum provided thereby.
    As shown in FIG. 2, the agricultural machine 1, which can for instance be designed as a loading wagon or baler, can comprise a pick-up device 2 for picking up harvested goods from the ground, said pick-up device 2 being a good sensor 3, for example in the form of a circumferentially the drivable spine drum 4, which picks up the stalk or leaf-shaped crop from the ground and transfers it to a post-arranged metering roller 5, optionally with interposition of transverse conveyors 6, for example in the form of transverse conveyor rollers. Said metering roller 5 can be arranged lying transversely to the direction of travel and can be drivable about a longitudinal axis extending transversely to the direction of travel.
    The said metering roller 5 can be designed as a overhead conveyor and can carry the harvested goods from the hopper 6 overhead and through a conveyor channel which extends above the metering roller 5 over the metering roller 5.
    Furthermore, the dosing roller 5 can be provided with a cutting unit 7, the cutting blades of which can comprise cutting blades hanging from above in the conveyor channel, which blades extend to the dosing roller 5, such that conveyor strips 8 of the dosing roller 5 project beyond the cutting blades.
    As shown in FIG. 2, the conveyor strips 8 of the metering roller 5, which are staggered outwards on the peripheral side of the metering roller 5, are arranged in several rows distributed over the circumference of the metering roller 5. The conveyor strips 8 of a conveyor row are not arranged along a straight parallel to the roller pivot axis 9, but are arranged with an oblique profile course.
    As shown in FIG. 2, the points or protruding ends of adjacent rotor rows 8 of a conveyor row 10 define a profile line 11, which in FIG. 2 is shown in striped. Because adjacent conveyor strips 8 are offset a lot further in the circumferential direction of the metering roller 5, such that they advance one after the other, respectively, the said profile line 11 runs obliquely with respect to the direction of the rotational axis of rotation 9, wherein the profile variation over the width of the metering roller 5 is, as seen, multi-tapered and has an inverted twist.
    Starting from the central portion 5m of the metering roller 5, the profile course of the conveyor strips 8 has two profile parts 11r and 111 which, in relation to the direction of the rotational axis of rotation 9, are inclined in opposite directions or screwed in opposite directions to each other. The profile sections 11 r and 111 can in particular in each case have a spiral contour.
    As shown in FIG. 2, each profile portion 11 r and 111 has a reverse twist. While the profile sections 11 r and 111 starting from the central section 5 m in respective inner lower sections 11 r 1 and 11 l 1 are chamfered in opposite directions such that farther-lying conveying sections 8 follow the farther-in conveying sections 8 each time, that is to say that the most inward-looking prong on a central portion 5 m in the circumferential direction as seen furthest to the front, while the conveyor strips always further out are then a lot further back.
    However, this chamfer of the inner lower parts 11 r1 and 11 l1 then turns towards the edge parts 5 r and 5 l of the metering roller 5. Subsequently, the slope of the aforementioned inner sub-sections 11 ri and 11 li decreases and the profile curve at a twist reversal point 12 obtains a reversal point. In the outer lower parts 11 ra and 111a, the profile line 11 is then oppositely slanted in the direction of the roller pivot axis 9. Starting from the said twist reversal point 12, the conveyor belts 8, which are always further to the outside, are each one further further in the direction of rotation staggered, such that the most outwardly located conveyor belts form the most forwardly conveyor belts with respect to the relevant lower parts 11 ra and 111a.
    By the means shown in FIG. The conveyor arrangement shown in Fig. 2 and its profile profile can be divided into a central portion of the metering roller 5, the harvested material transversely to the outside, while in the peripheral sections 5r and 51 of the metering roller 5, the harvested material is conveyed to the center together. As a result, a cross-sectional distribution of the crop material carpet as a whole can be achieved without building up excessive crop pressure on the side walls of the transport channel or the subsequent good collecting chamber.
    As shown in FIG. 2, the conveyor rows of the right and left profile sections 11r and 111 are offset on a central section 5m of the metering roller relative to each other in the circumferential direction, and advantageously in each case over the half division angle between two conveyor sections adjacent to the circumferential direction of a section section . As a result, approximately always at the same time many transport rigs with the cutting blades can engage and a smooth rolling run can be obtained.
