Claims

A vertical bearing 50 is to remain on the carrier 13 _X by means of self-adjusting running wheels. The of these strips 51 and 52 attached. In the bearing 50 there is a resistance line corresponding to the working position; the vertical axis can also be rotated; this axis is indicated at the bottom with a dashed line. This abutment end is connected to a horizontal shaft, but the standing line extends, as shown by the about which the impeller 39 is rotatable. The vertical figure 5 is clearly visible, very different from that of the axis is just below the bearing 50 with a working position of the star turning device according to FIG. A strip 55 is attached to the bearing 50, also in this position a point of application for the train to which a curved strip 56 is provided. force is almost on the resistance line. The ends of the strips 55 and 56 are provided with a star turning device, but in this case they are provided in the holes through which a locking pin moves in the direction U on the draw hook 45, which is guided on the 57. The lower end of the pin 57 can be inserted into one of the holes 54 at the other end of the frame beam 1 than the draw hook, so that 44 is fastened.

the vertical axis against rotation in the bearing In the position of FIG. 3 is the star turning device 50 is secured. In the same way as the impeller 15 converted into a swath turner, which is used for

39, the impeller 38 with the group of rakes is suitable for turning two swaths at the same time, where-

wheels 9 connected. processed by three rake wheels in each swath

The star turning device works as follows. When going away. In this way, the star turning movement of the star turning device according to FIG. 1 in Rieh- der for processing heavier swaths than in device V, where it is pulled away on the draw hook 44, 20 of the working position according to FIG. 1. The situation according to FIG. 3 the rake wheels, due to their inclined position 'is achieved in that the rake wheels 32, 33 and opposite the direction V, when touching the bottom 34 with their respective cranks from the side are set in rotation. As a result of this rotation, the rake rack bar 2 is released and the cranks are attached to the crop lying on the ground. The prongs 25 of the rake wheels extend 25 swath turner frame beams 1 are attached. Also in the direction of rotation of the rake wheels to the rear, in which case the star rake is not moved in the direction by any crop on the upwardly moving U on the draw hook 45, which again gets stuck near the tines. In this position, the rake wheels corresponding to this working position of the star rake are arranged in such a way that they lie in groups corresponding resistance line, move the material laterally by two rake wheels and 30 in the position according to FIG. 4, each rake wheel of the star turner forms a swath turner, which in itself forms a strip of terrain when the star turns in direction W for the simultaneous processing of three swath turner. Who owns it. The star turning device corresponding to this working position forms a single resistance line in this position is shown in the figure with a dashed wheel turning device. This position can be achieved by the th line indicated. As can be seen from the figure 35 that the carrier 13 is fixed in position 13 C , the star turning device is designed in such a way that the rest of the most important individual parts are again the point of application for the tensile force almost on the counter with the same reference numerals as in F i g. 1 designation line of the star turning device in this working net, but with a "C" lying next to those reference numbers. In this working position, the star right is assigned, which means that a user who is in a different position preferably designates the individual part on the draw hook 44. Which moves away from this working position, since in this case the inclination of the star-right turning device is the corresponding resistance line for slipping sideways, is reduced to a minimum, similar to the other figures, with an according to. dashed line indicated. As can be seen from the figure in FIG. 2 the star rake is visible, the draw hook 45 is redesigned for the fortderart so that each rake wheel uses the harvested crop moved by the 45 move of the star rake, the previous rake wheel should move the star rake as laterally as possible for transport. This situation, in which the star right is designed to be narrow; for this purpose the running wheels 36, which thus form a side rake, can be achieved 37, 38 and 39 in to the frame beams 1 and 2 by guiding the locking pin 30 allelic planes, the star being released, whereupon the carrier 13 , in the position 13 A 50 wender on the draw hook 45 is moved in the direction R and the locking pin 30 is in another; In this transport position, the running wheels 36 hole 27 can be performed, the carrier 13 _X and 38 is locked against rotation about their vertical axes in the new 13 A position. Then it has to be locked.

Locking pin 57 are released, whereupon the barrel In order to damage the prongs of the raking wheels and wheel 39 in the new position 39 A and to prevent the clogging 55 of the road surface, the raking wheels can lock pin 57 into another hole 54 by means of a lifting device the transport position can be, as a result of which the impeller 39 can be guided against rotation and is secured with respect to the bearing 50. The raking wheels of the other groups can be transferred to the new positions in the same way. 60

In the situation according to Fig. 2, in which the most important 1st star rake with one of running wheels items with the same reference numerals as in supported frame, the two each have a number F i g. 1 are designated, with those reference bearings bearing parallel frame bars for the numbers an "A" is assigned, which has a different receptacle of raking wheels, some of which denote position-occupying items, 65 of the raking wheels of the one frame bar are similar to Position according to FIG. 1 only the running bars (swath turning bars) on the other frame wheels 38 and 39 can be moved against rotation around their vertical bars (side bars) and axles are locked, while the running wheels 36 and 37 rotate at least one of the running wheels by 90 °

can be pivoted and locked in two positions relative to the frame that differ by about 90 °, while the other running wheels are designed as self-adjusting trailing wheels, characterized in that the side rack bar (2) carries vertical axes (6,7,8) around which the rake wheels (23,24; 32,33; 34,35) can be locked and swiveled in several positions, and that two clutches (44,45), which are spaced apart from one another, are provided on the swath turner frame beam (1) for attaching a traction device are arranged so that with their help, with appropriate adjustment of the swiveling, direction-determining impeller (or wheels), the device can be moved in two directions deviating from each other by about 90 °.
2. Star turning turner according to claim 1, characterized in that the rake wheels are arranged in a manner known per se on cranks and the cranks are pivotable about the crank axes relative to the frame.

3. Star rake according to claim 1 or 2, characterized in that the rake wheels sit in groups of two (23,24 or 32, 33 or 34, 35) on carriers (IS ₁ or 13 ₂ or 13 _S ), which are opposite the Seitenrechgestellbaiken (2) are pivotable.

4. Star turning device according to claim 3, characterized in that with at least one of the Carrier (13) an impeller (38) is pivotally coupled, which in several positions relative to the Carrier is detectable.
