Rotary mower with additional tools

The invention relates to rotary mowers with two or more with Mowing drums equipped with cutting blades and approximately vertical. In these known mowers, the cutting blades are usually located only at the bottom of the mower drum and around vertical Pivoting the bearing pin so that it faces larger obstacles * over can dodge. The crop then turns in opposite directions between two circulating mower drums pulled through and behind the mower Filed in practically unchanged condition. The one for hay extraction Required follow-up work such as turning, swaths and the like are here - as is the case with conventional mowers with cutter bar - often and to a considerable extent difficult for long, especially climbing cuttings such as clover, alfalfa, etc. Also, since the crop is neither kinked nor squashed, especially in the case of coarse-grained crop, it takes a relatively long time Drying time required.

The object of the invention is to remedy these deficiencies. It is solved by the fact that on the mowing drums in addition to the Normally customary cutting knives higher arranged tools for Cutting and / or for kinking and / or for squeezing the crop are arranged »Through these additional tools can

In other words, the mowing material continues as desired while mowing crushed and / or kinked and / or squashed, whereby the follow-up work can be made much easier and also shortened. A rotary mower designed in this way can also, for example used exclusively for chopping combine harvester straw or corn stalks or the like in order to improve these crops to be able to plow under. Furthermore, their own so-called Knickoder Squeeze tedders are not only dispensable, they also do not have to carry out their own operation.

According to a further feature of the invention, the additional Tools optionally attachable to the mowing drums, preferably as self-contained assemblies. For this purpose, they can for example on flat iron rings od, the like. Be arranged with the Mower drum screwed or clamped onto it. The mounts can also be attached individually to the mower drum, for example to be screwed on. This measure makes it possible to retrospectively add existing mowing drums as well, as required to equip with the mentioned additional tools. Furthermore, this also allows the number of cuts required in each case as well as determine the kink and / or pinch points and their intensity.

For the formation and arrangement of the additional cutting, There are numerous design and crimping tools Attachment options, such as the following description of the figures, which show some examples, can be found is. It shows

According to FIG. 1, four mowing drums 2 are mounted on the support frame 1, and cutting blades 3 are hinged to their lower end in a known manner are. According to the invention are at some distance above this Cutting knives other cutting tools U attached. these can be articulated to the mower drum similar to the lower cutting blades. Since, however, there are none at this height above the ground Significantly larger resistances, in particular no larger foreign bodies are to be expected, they can also be rigidly attached to the mowing drum. According to FIG. 3, they are on a flat iron ring S attached, which is clamped in a known manner, for example by a screw 6, on the mower drum. He exists advantageously from two interconnected by a hinge 7 Divide, this makes it possible in the simplest way to cut the " tools to attach or remove as required, to change their height above the cutting blades 3 or any Number of flat iron rings fitted with cutting tools to be attached.

The Fig. * Shows an embodiment for the individual attachment of the cutting tools 4. These are here in a bearing block 8 pivoted; however, they could also be firmly connected to it s «in. It is adapted to the outer surface of the mower drum and can be connected to it by screws or tendon fasteners With the appropriate arrangement of the fastening elements (thread looper od. Like.) In or on the mowing drum, the additional cutting tools can also be at different heights and Arranged in any number on the mower drum and for a short time

attached to or removed from it.

Furthermore, the mowing drums according to FIG. 11 can also have annular Cutting disks 16 may be provided, which can also be screwed to the mowing drums or in some other way, preferably easily detachable, are to be attached. To achieve a scissors-like cut, their cutting edges lie directly against one another and overlap one another.

With the additional cutting tools, the crop is cut into the desired lengths immediately when required, see above that it is much better in the subsequent haymaking can edit.

Figures 5 to 10 show exemplary embodiments for the arrangement of ribs on the mowing drums to keep the crop at the same time To be able to mow also bend and / or squeeze. Fig. 5 shows this is the view of a mower with four mower drums, on each of which several radially directed annular ribs 9 are arranged "Are advised that they drum on each other on neighboring mowers Stand gap. The outer diameter of the individual ribs is like this dimensioned so that it is close to the jacket of the adjacent mower drum reaches »They are useful, for example in the manner of the cutting tools according to FIG. 3, each individually on the Mähtroatmel arranged easily removable · This way can by their number, as well as by the use of ribs different Outside diameter their kinking and squeezing effect can be made very variable. By arranging ribs on just each one second Mähtronanel it is possible to have only a squeezing effect to achieve.

A particularly good kinking and squeezing effect results when 9 and 10 adjacent mowing drums with it are provided at the same height opposing annular ribs which have an interlocking profile on the outer circumference. According to Fig. 9, the left-hand mower drum is ribbed 10 provided, the circumference of which is formed in the shape of a knife. The right-hand mower drum, however, is provided with ribs 11, whose Perimeter is V-shaped. According to FIG. 10, ribs of the embodiment 10 and 11 are arranged alternately on each mower drum. Due to the meshing of the ribs, the crop is very intensely both kinked and squeezed at the same time. For clarification this effect is one stalk each in FIGS. 9 and 10 shown, the same also in Fig. 8. Of course, can the ribs can also be provided with other profiles, and / or ribs can also be used to adapt to different operating conditions different outside diameters can be used.

Fig. 8 shows an embodiment with helical lines Ribs 13, The slope of these ribs on immediately adjacent ones Mowing drums must of course run in opposite directions. This rib guide also allows a more targeted, in particular Generate an upwardly directed air flow, which causes an intensive spreading of the width of the mowed material.

FIGS. 6 and 7 show two exemplary embodiments for an arrangement of ribs IH parallel to the axis. Similar to the description of FIG. 5, the mowing drums can alternately be shown in FIG

* " ⁷ ". ' 009831/0342

Be provided with ribs. In the training according to FIGS. 7 and 8, at which the ribs of two adjacent mowing drums over each other cut, it is of particular importance that the mowing drums rotate synchronously, otherwise the ribs mutually would destroy.

To avoid the sometimes considerable forces when kinking or squeezing the Catching crop between the individual mowing drums can, according to FIG be connected to each other in the lower end of each mower drum axis is stored. "

Furthermore, the ribs are advantageously made of an elastic one Plastic or rubber, so that they can handle larger quantities of crop or be able to avoid larger foreign bodies.

Without departing from the basic idea of the invention, are self-evident other designs and variations are also possible. It would be conceivable, for example, to use individual or all of the mowing drums at the same time to be provided with ribs and with additional cutting tools in order to keep the crop at the same time while mowing crush as well as kink and / or squeeze.
