    Maize bit for a forage harvester
    The invention relates to a maize header for a forage harvester according to the preamble of claim 1.
    In the case of harvesting machines, a distinction is fundamentally made between those harvesters in which the crop is threshed, and between harvesters in which the crop is chopped. Then, when harvested crops such as wheat, barley or oats or harvested crop rape, harvesters are typically used, which are designed as combine harvester. Then, on the other hand, when corn is to be harvested or sorghum is harvested as crop, forage harvesters are typically used as harvesters. A trained as a combine harvesting machine, in which a crop to be harvested is threshed, has a mowing and infeed with several Mähorganen harvesting the crop under execution of a scissors-like cutting section. On the other hand, a harvesting machine designed as a forage harvester has a mowing and catchment system designed as a maize header with several mowing and intake elements driven in rotation around it. The present invention relates to a maize header of a harvester designed as a forage harvester, in which the crop to be harvested is chopped and therefore not threshed.
    Commonly known maize bits for forage harvesters have a cross member extending transversely to the longitudinal direction or direction of travel of the forage harvester and a plurality of longitudinal members extending in the longitudinal direction or direction of travel of the forage harvester, wherein the longitudinal members are positioned in front of the cross member when viewed in the harvesting direction or direction of travel. The side rails accommodate mowing and catching organs of the maize header, the mowing and drafting devices serving to separate the crop in a substantially horizontal direction. The mowing and intake organs are driven by the same associated gear.
    From the practice known corn heaves continue to have Einweiselemente and skids, the Einweiselemente are seen in the harvesting or direction of travel before the mowing and catching organs and direct the harvested crop in the direction of the mowing and intake organs, and wherein the skids of the support serve the maize header in harvesting operation on a harvested area.
    When known from practice cornbites both Einweiselemente and the skids are attached to the mowing and intake organs associated gearboxes, so that in the harvesting operation on the intake organs and skids acting forces and moments must be absorbed or intercepted by the gearbox or the gearboxes , As a result, they must be dimensioned accordingly, resulting in a high weight for the maize teeth.
    A further disadvantage of maize bits known from practice is that contaminants accumulate in the area of the gear units and skids, which increase the weight of the attachment or of the maize bit. The dirt can detach again when driving on the road, as a result of which the roadway can be contaminated disadvantageously. In addition, crop flow elements can be contaminated, which can lead to contamination of the feed or even damage to the chaff elements when reused.
    On this basis, the present invention has the object to provide a novel maize header for a forage harvester. This object is achieved by a maize header for a forage harvester according to claim 1. According to the invention, the longitudinal members are designed as support brackets, which are connected at one end to the cross member, wherein the Einweiselemente and / or the skids are attached to the side rails such that the side members of the forces acting on the Einweiselemente and / or the skids forces and moments below Bypass of the mowing and intake organs associated transmission transmitted to the cross member.
    For the purposes of the present invention, the guide elements and / or the skids on the trained as a support brackets longitudinal members, wherein the side members take the harvesting operation on the Einweiselemente and / or the skids forces and moments and transferred to the cross member, namely, bypassing the mowing and intake organs associated gear.
    This makes it possible to dimension the gear or the gear housing with smaller dimensions, whereby the maize header can be made easier. Particularly preferred is a variant of the invention, in which both the Einweiselemente and the skids transmit their forces and moments, bypassing the mowing and intake organs associated gearbox to the cross member, namely the fact that both the Einweiselemente and the skids on as Support brackets trained longitudinal members are attached.
    Preferably, the Einweiselemente are connected at an end facing away from the cross member end of the longitudinal members with the same and / or the skids extend on an underside of the side members and are connected at the front under the Einweiselementen and on side walls of the side members with the same. This connection of the Einweiselemente and / or skids on the designed as a support brackets longitudinal members is particularly advantageous.
    According to an advantageous embodiment of the invention, the longitudinal members have a closed shape and surround the mowing and intake organs associated gear, wherein output-side shafts of the transmission penetrate the side members to drive the mowing and catching organs. The longitudinal members are not rugged and preferably have a smooth surface, whereby dirt accumulations are prevented or at least reduced.
    It is particularly advantageous to form projections of the cross member directly on a longitudinal support designed as a support bracket. Such T-shaped brackets then form modules that can be connected to each other at their cross-beam approaches and form a header or a maize header or a single arm of a Mähvorsatzes. To realize different distances between the side rails modules can be produced with different lengths cross-beam approaches.
    Preferably, the T-shaped console modules are made of upper and lower half-shells, which are manufactured in a deep-drawing process and are welded or screwed together. In this way, console modules with different length cross member approaches can be made with a single deformation tool. These form a modular system of almost equal parts, with which mower headers or maize headers of different working widths can be built. It is also possible to provide only a half-shell at the bottom, which is closed at the top with a (nearly) flat lid
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Embodiments of the invention will be described, without being limited thereto, with reference to the drawings. Showing:
    Fig. 1 is a side view of a maize header according to the invention for a forage harvester; and
    FIG. 2 is a plan view of the maize header of FIG. 1. FIG.
    The present invention relates to a maize header 1 for a forage harvester.
    1 and 2 show a section of a maize header 1 for a forage harvester in the region of a transversely extending to the longitudinal direction and thus direction of travel or harvesting direction of the forage harvester cross member 2 and in the longitudinal direction or direction and thus harvesting direction extending longitudinal member 3. Typically a plurality of such longitudinal members 3 present, which are positioned in front of the cross member 2 seen in harvesting direction and at a distance parallel to each other.
    On the longitudinal beams 3 mowing and intake organs 4 of the maize header 1 are added, each mowing and intake member 4 is assigned a gear 5, via which the respective mowing and intake member 4 can be driven.
    As can be seen from Fig. 1, extends within the cross member 2, a transverse shaft 11, from which branches off in the region of each longitudinal member 3, a longitudinal shaft 12 which is coupled to the corresponding gear 5. Drive power introduced into the longitudinal shaft 12 via a drive unit, not shown, can be introduced into the mowing and intake elements 4, starting from the transverse shaft 11 via the longitudinal shafts 12 and via the gear mechanism 5.
    In addition to the cross member 2, the longitudinal members 3 and the mowing and intake organs 4 received by the longitudinal members 3 with the gearboxes 5 assigned to them, the maize header 1 comprises insertion elements 6 and skids 7. The insertion elements 6 are viewed in front of the mowing and drawing-in organs in harvesting direction 4 positions and guide the harvested crop in the direction of the mowing and drawing-in organs 4. The skids 7 serve in harvesting operation to support the maize header 2 on a harvested surface. For the purposes of the invention, the longitudinal members 3 of the maize header 1 are designed as support brackets which are connected at one end 8 to the cross member 2, wherein the guide elements 6 and / or the skids 7 are fixed to the longitudinal members 3, namely such that the side members 3 transmitted to the guide elements 6 and / or the skids 7 in the harvesting operation forces and moments, bypassing the mowing and intake organs 4 associated gear 5 transmitted to the cross member 2.
    Preferably, both the Einweiselemente 6 and the skids 7 are attached in this way to the longitudinal members 3, the support brackets.
    In a particularly advantageous embodiment, stubs or projections of the cross member 2 are formed on the left and right of the support bracket, which consist of a part together with the support bracket.
    The mowing and intake organs 4 associated gear or the transmission housing 5 must therefore only absorb and support driving forces and drive torques or forces acting on the mowing and intake organs in the harvesting forces and moments, so that the transmission or the gear housing 5 are dimensioned smaller can. This can be realized for the maize header 1 a weight saving.
    The Einweiselemente 6 are connected at an end remote from the cross member 2 9 of the longitudinal member 3 with the same, wherein the Einweiselemente 6, which are also referred to as Einweisfinger attack on a corresponding carrier 13, via screw 14 at the end facing away from the cross member 2 9th is connected to the corresponding side member 3.
    The skids 7 are positioned on an underside 10 of the longitudinal members 3 and preferably attached to side walls 15 of the respective longitudinal member 3 at the same. In addition, the skids 7 are hooked at the front.
    The mowing and intake organs 4 associated gear 5 are also based on the longitudinal members 3, namely gear housing this gear. 5
    The longitudinal members 3, which form support brackets, preferably have, together with the gear 5 used in each case, a closed shape or contour which surrounds the gear 5 associated with the mowing and intake elements 4. The closed shape has a smooth outer contour on which little dirt can accumulate or adhere. Lockable maintenance openings can be provided on the underside.
    Output-side shafts 13 of the transmission 5 penetrate the housing-like bearing support 3 for driving the mowing and intake organs. 4
    The longitudinal members 3 are preferably formed as a sheet metal construction of a high-strength steel, to carry out the same with low weight. Preferably, the support brackets, consisting of side members 3 and silent or approaches of the cross member 2, made of an upper and lower half-shell, which are manufactured in a deep-drawing process and are welded or screwed together.
    In harvesting operation on the guide elements 6 and the skids 7 acting forces and moments can therefore be absorbed by the sheet metal construction of the longitudinal member 3 and derived bypassing the gear 5 on the cross member 2. Since these forces are not derived via the gears 5, namely the gearboxes of the same, they can be carried out with smaller wall thicknesses and therefore with less weight. The closed, box-like shape of the support brackets avoids the entry of contaminants in the area of the gear 5.
    All drive-side components are within the housing-like, designed as a support brackets longitudinal member 3. The drive components are therefore protected by the side members 3. A contact with driven, rotating elements or fibrous crop residue that could be wound up, can be excluded as far as possible.
