    The invention relates to an agricultural device for summarizing crops. In particular, it is about a band rake, which collects the crop, such as hay or emd, by means of a receiving device (1) or pick-up from the ground and on a conveyor belt (4) throws. The latter may be a screen or fabric tape, whereby the conveying plane (8) is permeable to air. By at least one vacuum source, for example a suction fan (7), an air flow to the conveying plane (8) is effected. As a result, the approaching, thin hay, Emd or straws also tuft-wise reliable on the conveying plane (8) pull and carry on. Even in unfavorable topographical conditions, especially on slopes, the crop no longer slips uncontrolled from the conveyor belt (4) and can be collected easily and possibly accumulate to even rows or swaths.

    Description: The present invention relates to an agricultural implement for gathering crop material with at least one conveyor belt, in particular a belt swather.
    A band rake is an agricultural device that serves to summarize hay, or emd, straw, silage or the like crop, which is to be heaped to uniform swaths, or rows. As a rule, the crop is already dry enough at this time that it can be introduced. The swaths formed by the band swather can be collected easily, for example with a loader wagon. The crop can also be pressed into bales or previously, for even better drying, turned again. Depending on the version, a band rake can be pushed, that is, be arranged on the front of an agricultural vehicle, or he can be pulled accordingly behind the vehicle ago.
    The belt swather collects the crop by means of a receiving device from the ground. This receiving device, also called pick-up, has rake-like arranged prongs, which preferably rotate and feed the crop at least one conveyor belt. The latter runs transversely to the direction of travel and throws the collected crop sideways again on the ground, where there forms an elongated row or swath due to the driving movement. Alternatively, the crop could be filled via appropriate conveyors but also directly into a loader wagons. For the invention, the area of the conveyor belt is primarily important, and several conveyor belts are conceivable, which could be arranged behind or next to each other, for example.
    If the band swather used in particular for swathing of hay or emd, can not be guaranteed by the previously known devices often that the arrived on the conveyor hay or emd is reliably transported from there to the side and unloaded to clean steam. Although known conveyor belts have ribs which are to promote the conveying effect of the belt. This works on level ground and in calm weather reasonably well. But especially in hilly terrain or in mountain areas, where the swaths are occasionally formed across the slope, the conveyor belt, according to the slope, often leaning heavily to a vehicle side. In addition, natural slopes are usually anything but even, so it can also result in a bumpy ride with major shocks. Especially with these topographical conditions, but not only there, tends the rather light hay or Emd not properly taken away from the conveyor belt and / or in an undesirable direction to slip back from the conveyor belt. If there is any wind at all, it is almost impossible to form sensible swaths in unfavorable terrain. This means that either hay or emd is not completely introduced or considerable additional work is required.
    On the basis of these findings, the invention has the object to provide an agricultural device, in particular a band rake, which reliably conveys the collected crop for further use, for example, to the side of an agricultural vehicle, and even in unfavorable topographical conditions can be used.
    The inventive agricultural equipment, in particular belt rake, corresponds to the characterizing features of claim 1. Further advantageous embodiments of the inventive concept can be seen from the dependent claims.
    Hereinafter, preferred embodiments of the invention will be described in more detail with reference to the drawing.
    Fig. 1 shows a band swather in plan view;
    Fig. 2 shows the same band rake in side view;
    Fig. 3 shows a section along the line A-A in Fig. 1;
    4 shows a section along the line B-B in FIG. 2.
    The illustrated in the present example agricultural device for summarizing crop is used as a band swather on the front of an agricultural vehicle, ie in overrun operation. For this purpose, a holding device is provided for preferably detachable mounting and for lifting and lowering the band rake in a working position. With a correspondingly modified holding device but also a version for towing operation would be possible, in which case possibly also wheels could be present.
    In the forward direction is in any case a receiving device 1, or a pick-up available. In the present exemplary embodiment, this receiving device 1 has a rotational axis 2 extending transversely to the direction of travel, through which the crops arranged in the manner of a rake and with co-rotating teeth 3 feed the crop to the at least one conveyor belt 4. In this area, preferably baffles are present, which prevent the crop from being thrown in an undesired direction thereof, but direct targeted to the conveyor belt 4. From the basic principle, this technique is known. The conveyor belt 4 also runs transversely to the direction of travel and is guided as an endless belt over at least two rollers 5 and 6, of which at least one is driven. The latter are each arranged at the deflecting ends of the conveyor belt 4, with support rollers being possible between them.
    The above-mentioned object, the crop, for example, hay or emd to keep reliable on the conveyor belt 4 and to convey to the desired location, according to the invention accomplished by the crop is sucked onto the conveyor belt 4 and held there. For this purpose, at least one suction device is present. In the illustrated embodiment, this suction device has at least one suction fan 7, wherein as an example five suction fan 7 are shown. But it can also be only three or more than five suction fan. Ultimately, this also depends on the width of the agricultural implement or belt rake, or on the length of the conveyor belt 4. The suction fans 7 are arranged below the conveying plane 8 of the conveyor belt 4 so that they suck air from above through the conveyor belt 4 down.
    Instead of a plurality of individual suction fans 7 may alternatively be present only a single suction device or a single suction fan 7, which is connected via at least one suction line with the region of the conveying plane 8. The at least one suction line may be provided on its surface with mammalian openings or branches, whose free ends are formed as mammalian openings. Analogous to the example shown, five branches each with a mammalian opening could be provided. The latter could be designed in the form of a suction funnel to act on a larger portion of the conveying plane 8. Depending on the technical equipment of the agricultural vehicle on which the band rake is used, it would also be possible to use a compressed air device which is available at most. This could operate as a vacuum source serving suction. In the area below the conveying plane 8, in order to improve the suppression, at least one vacuum chamber can be formed. For this purpose, in this area corresponding, arranged in the strip running direction side walls and possibly also to provide transverse walls. Also conceivable are combinations of the aforementioned technical devices.
    The conveyor belt 4 is formed permeable to air at least in a middle band region of its conveying plane 8. That is, there are any openings in the conveying plane 8, which allow an air flow through which a crop can be sucked onto this conveying plane 8. In order to allow air flow through the conveying plane 8 through, holes or slots in the conveyor belt 4 may be present. It makes more sense, however, to make the conveyor belt 4 permeable to air by being designed as a sieve belt, grid belt, mesh belt or fabric belt.
    Thanks to this construction, the crop, which is thrown by the relatively rapidly rotating tines 3 of the receiving device 1 in the direction of the conveyor belt 4, attracted by the delivery level 8 and held there. The crop, for example, light, dried hay or Emd, is thereby reliably transported from the conveyor belt 4 to where you want it. This can be, depending on the direction of the conveyor belt 4, either in the direction of travel left or right of the band raker. Alternatively, the collected crop could be fed by the present agricultural equipment directly to a loader wagon or the like.
    When agricultural equipment according to the invention, in particular band rake, thus results in the area below the conveying plane 8, a suppression. Since, especially in the illustrated embodiment, with the suction fans 7, the sucked air is pressed down, there is below this suction fans 7, however, a positive pressure. The latter can be used meaningfully. Namely, where not a Saugsondern blowing effect is needed. Thus, a cleaning air stream 9 can be blown into those areas of the belt swather, for example on the receiving device 1 or between this and the conveyor belt 4, where crop, or hay or Emd could set. It is also conceivable at least one valve or the like to divert the cleaning air flow 9 either in the said areas or to the outside. In the latter case, the cleaning could be turned on only when the collection work is interrupted or finished.
    The receiving device 1, also called pick-up, may be formed mehrgliedrig for the purpose of adaptation to the respective terrain, or to the bumps. For example, there may be three members 10 that are movable relative to each other, at least with respect to an up and down movement. The function of the conveyor belt 4 and the associated vacuum source, for example, the multiple suction fan 7 having suction, is thereby affected in any way. The conveyor belt 4-carrying components of the belt swather could be movable for this purpose so that the conveyor belt 4 follows the movements of said members 10.
    Of course, it is within the scope of the invention according to claim 1, the agricultural device, in particular the band raker and its components in detail differently designed to be designed. In any case, it has surprisingly been found in practical experiments that the approaching, thin hay, Emd or straws are pulled tuft-wise reliable on the conveying plane 8 and selectively transported on.
