The invention relates to a flail forage harvester with adjustable about a horizontal axis Counter support for the rotating flail knives. The task to be solved with the subject matter of the invention is seen in arranging the counter layer more advantageously than before and handling it during the transition to simplify to a different chop length.

With Schlegel forage harvesters, a shorter chopping of the crop is achieved when the rotating Flail knife interact with a fixed counter knife. To a different length To get the chopped material, the distance between the counter knife and the flail knives can be changed made.

Schlegel forage harvesters are known, on the intake-side, height-adjustable jacket wall of which several Flaps are arranged pivotably about a horizontal axis. At the free ends of these flaps counter knives are attached. In the rest position, these loosely oscillating parts hang down vertically. First when the flail forage harvester moves in the direction of travel, the crop presses the flaps and thus the counter knife on an arc into the machine and at the same time up close to the rotating flail knife where the crop is chopped. This design has the disadvantage on that the position of the counter knife to the rotation circle of the flail knife changes constantly, d. In other words, because the vegetation is never even, the crop is always chopped at different lengths, which is very disadvantageous for the production of silage (short length) or fresh forage (long length) is. In addition, this design creates unfavorable delivery conditions between the lower one Edge of the fixed housing wall and the movable flaps carrying the counter knife.

In a further known Schlegel forage harvester, the counter knife is on the casing wall on the intake side attached to the housing. The jacket wall and thus the counter knife can be in one in the Side walls of the housing arranged elongated hole guide can be pivoted in a certain area. For this purpose two large screws have to be loosened, the jacket wall has to be adjusted and the screws need to be tightened again. This requires a relatively large tool that has a lot of space busy and not always at hand. Furthermore, the effort required to open the mostly rusted ones Screws big. The manual effort is so great that there is no quick adjustment Can be talked about. With the disengagement of the counter knife there is always an adjustment of the Flail forage harvester

Shell wall required, which is particularly unfavorable with wet crops, unless you have the The counter knife pushes back or removes it by loosening the screws.

Furthermore, it is in the case of cutting inserts, in which, as is known, the cutting knives are arranged in a stationary manner are and the insert drum serving as a counter support revolves, known, the cutting knife on a parallel to be fixed to the insert drum arranged profile, which can be rotated about its longitudinal axis and can be locked in different positions to bring the cutting knife into or out of action to be able to. As soon as the cutting knife by appropriately twisting the profile carrying it are brought out of action, no more cutting takes place.

In contrast, the invention consists in that as a counter-surface for the rotating mallet an im Housing rotatably mounted, lockable in different positions profile is arranged that Carrier of an optionally openable counter knife is. In this way, in every position of the Opposite forming profile take place a cutting process, depending on the position of the profile either Short or long chopped goods can be harvested. For chopping short crops, the Profile arranged counter knife made effective, while for harvesting long chopped material the Profile is twisted so that the counter knife arranged on it comes out of action and the profile itself forms the counterpart. This handling can be carried out conveniently and quickly, which is often the case changing working conditions is advantageous.

Another advantage can be seen in the fact that the designates, on each of the side walls 2, an adjusting feed path of the crop is arranged both in the single organ 3. The latter are through a follow-up located counter knife as well as in the position 20 following described in more detail profile 4 with it ment of the profile, in which this forms the counter-surface, attached, for example four-fold subdivided runs approximately evenly, only with the difference that counter knife 5 is connected. Since both adjusting elements 3 that in the position in which the counter knife are effectively constructed structurally the same is only intended below is, the goods are drawn in over a sharp knife edge and described an adjusting device.

is designed as an eccentric as a circular in cross section, but flattened 45.

In order to ensure perfect pivoting of the eccentric change of the inlet profile with respect to the raw material 14, the web 16 on the corrugation circle of the flails is kept shorter than the legs to end longer chopped material. The ends 19 extend while maintaining the most favorable currents, the latter touching a disk during clamping. If 50 20 is ineffective, which then in turn has several spring plates 21 counter-knife, the material will easily and quickly come into contact with the clamping piece 12. The nose 17 pulled away from the shaft, whereby the eccentric lever 14 is elongated in the longitudinal direction of the web of chopped material is achieved. By flattening the 16 so arranged that it is for the purpose of locking the shaft, the counter knife can be fastened in a simple manner between the ribs 7 of the locking device. The counter plate 6 attached to the shaft can be held,
knives and the necessary fasteners As is particularly evident from FIG. 3 and 5, outside the cutting edge in the circular profile, the profile 4 can be a shaft that is embedded, for example, whereby even firmly adhering dirt is rotatably mounted several times in tabs 22, which can only slightly hinder the rotary movement. but only one is drawn. The tabs 22 The dirt located in the cavities needs 60 itself are adjustable with the intake side, which does not need to be compressed. Another possibility of rotation of the flail knives 31, partially circumferential, for rapidly changing the distance between the giving jacket wall 23 of the flail forage harvester 1, counter-surface to the flails, is firmly connected according to the invention. In order to be seen on the shaft 4 that the shaft together with the counter knife 5 provide a secure support, the counter knife, the eccentric levers and the 65 is the shaft according to the length of the counter-adjustable, the rotation circle of the flail partially knife the one side in a certain position surrounding wall or the like. Flattened by moving the eccentric lever 14. The length of the clamping piece on the counter knife 5 on the housing side walls does not quite correspond to the width of the

Shell wall 23 of the flail forage harvester 1. A point at which the counter knife 5 is attached to the shaft 4 F i g shows. 5. The shaft 4, like the counter knife 5, has a bore through which a preferably truss-head screw 24 for connecting the two parts pushed through and secured will. It is secured by a nut 25 and a spring ring 26, which for this purpose on a Recess 27 of the shaft 4 are in contact. As further from FIG. 5 can be seen, for example, close to this Place a bracket 28 for a pivotable sheet metal 29 by means of screw 30 attached. On the sheet metal 29 themselves holders for baffle plates 33 are provided.

The operation of the device according to the invention is as follows:

If you want to achieve short chopping lengths, the distance between the flail knife 31 and the counter knife 5 be as short as possible. This corresponds to the counter knife position shown with solid lines according to FIG. 5. In this case, the eccentric lever 14 is in the position shown in FIG. 2 with solid lines position shown, d. that is, the lug 17 of the eccentric lever engages between the upper ribs 7 of the locking plate 6. In this position, the eccentric lever 14 is held by the pressure of the spring plate 21, the one end against the end 19 of the eccentric lever, the other end against the locking plate Press 6. The crop now passes the counter knife edge on the movement path 34 and becomes cut quite short there (mainly for silage).

If, on the other hand, you want longer chopped material, this can be done in various ways. Particularly when the crop is wet, the counter knife 5 is disabled by turning the eccentric lever 14 pivoted about the pivot pin 15 from its position described above, whereby the spring plate 21 relax. Now the eccentric lever 14 can about the axis of the shaft 4 be pivoted in the clockwise direction of rotation by about 90 ° (dash-dotted representation in Fig. 2), wherein the wave is carried along. Finally, the nose 17 can be inserted into the lower ribs 7 of the locking plates 6 can be locked into place. The counter knife 5 is now in the FIG. 5 evident, with position shown in dash-dotted lines, d. That is, the cutting edge of the counter knife 5 is ineffective.

The crop slides easily and quickly on its trajectory 35 over the curve of the shaft 4. From this it follows that the crop is less cut, but rather torn by the flail knives 31 with long fibers will.

The length of the chopped material can also be changed by changing the distance between the shell-side Wall 23 with the shaft 4 attached to it changed to the rotation circle of the flail knife 31. This Process can be used both to change the length of the chopped material and to readjust it as a result of wear the flail knife 31 take place and can be carried out in two ways. The first adjustment option provides that the shaft 4 together with the counter knife 5, the eccentric levers 14 and the adjustable, the rotation circle of the flail knife 31 partially surrounding wall 23 by moving of the clamping pieces 12 can be adjusted on the locking plates 6 arranged on the housing side walls 2 and can be locked in different positions. With the second adjustment option, the entire adjusting members and the wall 23 as a closed unit with respect to the housing side walls adjusted and locked. To do this, it is necessary to loosen the screws 10.

As already mentioned at the beginning, each housing wall 2 has an adjusting member 3 so that the Adjustments of the eccentric lever 14 must be carried out twice. But it is also possible get along with only one the shaft 4 actuatable adjusting member 3 when the locks for the jacket wall 23 and the shaft 4 are carried out separately. The latches don't have to must be done via ribs 7 and 17, respectively. For example, it is also possible to use the locks Segments, notches, stops, bolts or the like to make, with more than two locking end positions can be provided. The locking of the shaft 4 can also, for example, with a Lever arranged approximately in the middle of the shaft on the jacket wall 23, which are perforated for this purpose and is provided with a locking device.
