    The invention relates to a mobile mower with a mower and a drive for the mower, according to the preamble of claim 1. Mowers for crop are known in different designs. In most cases, the crop is cut by ground-guided cutting elements and either stored on the ground or fed to a collecting container. In many applications, it is desired that the crop is not merely stored, but removed from the mowing area. This applies, for example, to flood dams or dams from relief basins on which the crop should not be left lying, as otherwise it would be swept along by the next water movements. In general, leftover crops also act as fertilizers for renewable crops, thus providing unwanted, faster growth.
    The cut crop could of course be fed to a collecting container and disposed of. Against such an approach, there are increasing concerns about the organisms contained in the crop, which are sometimes considered important for the local habitat. Based on these considerations, the crop should be left on the ground for a certain period of time to protect these organisms and allow them to leave the crop. Above all, municipal landowners are increasingly confronted with such requirements.
    In addition, the turf should not be injured during the mowing process, so that the surface load must be kept low. The mowing devices must therefore be designed accordingly easy. A lightweight and compact design is particularly advantageous for the above-mentioned use on flood plains dams or dams of relief basins, where sometimes strong slopes must be edited.
    It is therefore the object of the invention to provide a mowing device that can be built small and compact and comparatively inexpensive and even with difficult
    Terrain with strong and sometimes humid vegetation can be used, the crop is removed from the mowing but not directly collected.
    This object is achieved by the features of claim 1. Claim 1 relates to a mobile mower with a mower and a drive for the mower, is proposed in the invention that the mower is designed as a cutter bar with at least two along the cutter bar and each rotatable about a vertical axis of rotation mower discs, wherein of the at least two mower discs are driven two adjacent mower discs with mutually opposite directions of rotation, which form a collection area for the crop in the region of their smallest spacing, and above the mowing bar a cover is provided on the upwardly leading ejector tube with a throwing fan for the crop is arranged, wherein the throwing fan has a paddle wheel, the throwing blades extend into the collecting area formed between the cover and cutter bar.
    The mower is initially designed as a cutter bar with mower discs, which are each arranged rotatably about a vertical axis of rotation. The cut crop is thereby moved by the mowing discs in the direction of rotation of the mower discs. Since, according to the invention, two adjacent mowing disks are provided which rotate in opposite directions, the crop is fed to a common collecting area. This collection area is the area of least spacing of the two adjacent mower discs. This collecting area pass through the throwing blades of the impeller of the throwing blower. A throwing blower is a mechanically and pneumatically operated conveying blower, which has a paddle wheel and a housing arranged concentrically with the paddle wheel. The crop is accelerated by the blades of the paddle wheel on the peripheral speed and thus ejected through the ejector tube. The paddle wheel is therefore also referred to as accelerator. A certain airflow has a supporting effect. The ejection height is limited to about 15 meters, but it is sufficient to deposit the cut milled material away from the mowing area, so that it can no longer affect the further mowing process. Also, clogging or misplacement of the mower can thus be prevented. For the drive of the throwing blower, it is preferably proposed that the same drive be provided for the mowing discs of the mowing bar and for the throwing blower. The drive is preferably arranged above the cover and connected via a fan shaft with the throwing fan and a deflection gear with the mower discs of the cutter bar. The cover on the one hand creates the conditions for collecting and ejecting the cut crop by the throwing fan, and on the other hand provides protection of the drive against contamination. The torque of the drive is transmitted via a deflection gear on the arranged below the drive mower discs. The distribution of the torque on the individual arranged along the cutter bar mower discs can be done via gear or belt transmission and the like.
    Furthermore, it is proposed that the front edge of the cover in the direction of travel lies in the direction of travel in front of the foremost peripheral region of the mower discs. In this way, the mower to be cut first comes into contact with the foremost edge of the cover and is therefore pre-bent before it comes into contact with the cutting blades of the mower discs. This bending of the crop improves the subsequent cutting process and the subsequent transport of the cut crop through the mower discs to the collection area.
    Preferably, the mobile mowing device according to the invention will be formed as part of a self-propelled mowing vehicle, which can thus be made small and compact and thus can be used on difficult terrain, either providing space for a driver, or may be designed as a remote-controlled vehicle , The mobile mowing device could also be designed so that it is not self-propelled and instead can be coupled to another vehicle to be pulled or pushed by him.
    The invention will be explained in more detail below with reference to an embodiment with reference to the accompanying drawings. It show here the
    Fig. 1 is a perspective view of an embodiment of a mowing vehicle with a mowing device according to the invention, and the
    2 shows a further perspective view of the embodiment according to FIG. 1.
    1 and 2 show a mowing vehicle with a driver's cab 1 and a crawler-type traction drive 2. In the front region of the mowing vehicle, a mowing device according to the invention is arranged with a mowing bar 3 which, in the exemplary embodiment shown, has three mower disks 4a, 4b rotatably arranged along the mowing bar 3. 4c. Above the cutter bar 3 is a cover 5. At a breakthrough of the cover 5, a throwing fan 6 is arranged with a paddle wheel, the throwing blades 10 extend to below the opening of the cover 5 and into a collection area for the cut crop.
    The throwing fan 6 is connected via a fan shaft 12 on the one hand with a drive 7 and on the other hand with a deflection gear 8. The deflection gear 8 directs the torque from the fan shaft of the drive 7 to the cutter bar 3, where it is distributed to the mowing discs 4a, 4b, 4c. Here are located below the cover 5 parts of the deflection gear 8 are covered by a frusto-conical housing 11 to secure it from contamination. The housing 11 further connects the cutter bar 3 to the cover 5 and thus increases the structural stability of the arrangement. Another housing 11 is also located at the opposite end of the cutter bar 3, which includes the bearing of the outermost mower disc 4c. The throwing fan 6 is further connected to an upwardly leading discharge pipe 9.
    The mower discs 4a, 4b, 4c are each rotatably arranged about a vertical axis of rotation. The cut crop is thereby moved by the mower discs 4a, 4b, 4c in the direction of rotation of the respective mohawl 4a, 4b, 4c. Of the three mower discs 4a, 4b, 4c, two mowing discs 4a, 4b lying directly next to one another move in the opposite direction of rotation, as indicated in FIG. 2 by means of the arrows. The outermost mower disk 4c moves in the same direction as the central mower disk 4b. The cut crop is therefore transported from the outermost mower disk 4c to the central mower disk 4b and from there in the direction of the first mower disk 4a. The first mower disc 4a transports the cut crop again in the direction of the central mower disc 4b. The crop is therefore guided together in a region of the smallest spacing of the two adjacent mower discs 4a, 4b. This area is therefore also referred to as collection area. This collection area is traversed by the throwing blades 10 of the throwing fan 6.
    The crop is thus removed with the help of the throwing blades 10_des throwing blower 6 and the ejection tube 9 from the mowing area and ejected at a greater distance, so that it can no longer affect the further mowing. Clogging or misplacement of the mower can thus be prevented. For the throwing fan 6 and the mower discs 4a, 4b, 4c of the cutter bar 3, the same drive 7 is also used, which is arranged above the cover 5 for the cutter bar 3. As mentioned, the cover 5, on the one hand, creates the conditions for collecting and removing the crop by means of the throwing fan 6 and, on the other hand, provides protection of the drive 7 against contamination.
    The mowing device according to the invention can thus be made small and compact and comparatively inexpensive, and can also be used in difficult terrain with strong and sometimes even wet vegetation.
