The invention is a further development of a device for the lateral displacement of on the Crop lying on the ground according to patent 1115 507.

The purpose of the invention is to make such a device easy and quick to use with a tractor and to be able to quickly lift the raking wheels off the ground.

According to the invention this is achieved in that the device by means of the rake wheel axes at least approximately parallel pivot axis to the hydraulically movable three-point coupling of a Tractor is connected in such a way that the raking wheels with the rigid support carrying them by means the three-point hitch can be lifted off the ground and that the rake wheels in the raised position only be carried by the pivot axis. In this way the device has a simple frame structure, and the device can be raised quickly. The last is important, for example with Turning the tractor and the raking device at the end of a strip of soil to be worked or when moving the device into a position suitable for transport. In addition, the device adapts itself adapts well to uneven floors during operation.

A particularly good ground contour following in the working position as a broad turner is achieved when the the rack bars carrying the rake wheels about a pivot axis extending parallel to the row of rake wheels is rotatable with respect to the three-point hitch.

An embodiment of the invention is shown in the drawings.

F i g. 1 is a plan view of an inventive, Device connected to the lifting device of a tractor for lateral displacement of crops lying on the ground in side-to-right position;

F i g. 2 is a side view of FIG. 1 in the direction of arrow II;

F i g. 3 is a plan view corresponding to FIG. 1 in the working position as a broad turner.

According to FIG. 1 to 3, the tractor 100 has a hydraulically movable three-point coupling with the three rod ends 101, 102, 103. The ends of a beam 105 designed as bolts 104 are articulated to the rod ends 101, 102. Two support rods 106, 107 run obliquely upwards from the beam 105 , the upper ends of which are articulated to the rod end 103 and the lower ends of which are articulated to the beam 105 . A horizontal bracket 108 provided with holes 109 is firmly connected to the beam 105 . A locking pin 110 can be inserted into the holes 109 in such a way that this device can be used to move crops lying on the ground to the side

also engages in a hole in the end 111 of a bushing 112 which is longitudinally displaceable on the bracket 108 in several positions. The other end 113 of the bushing is articulated to the beam 105 about a vertical axis. A chain 114 connects the rod end 103 to a hook 115 of the bracket 108. An axle 116 is rotatably mounted in the socket 112. A pin 117 can be inserted in one or more positions of this axis through a hole in the socket and a hole in each of the axis 116 , so that the axis 116 can be fixed in one or more positions.

The end of the axle 116 is, reinforced by support rods 119 , connected to the center of a rigid beam 118 . At 121, 122, 123, 124 four axes 125 running parallel to axis 116 are attached to this carrier 118 , on each of which a rake wheel 126 is freely rotatable. In the in F i g. 1 are shown on the axles 125 attached at 122 and 124 behind the rake wheels 126 mounted thereon and support members provided with shoes 127 are attached. The rake wheels can have a design known per se. The axis 116 can expediently move around a

know angle twist in the .. socket 112 , whereby a favorable distribution of the weight of the frame and the rake wheels 126 on the shoes 127 and the hydraulic clutch of the tractor is achieved. This measure can also be provided if there are no shoes.

The rigid support 118 can be reversed particularly easily, with the frame parts remaining connected to one another. For this purpose, the frame is raised so high from the ground with the aid of the hydraulic coupling of the tractor that the axis 116 can be rotated through 180 ° in the socket 112. The shoes 127 can also be brought into the reverse position, in which case the shoes can then be arranged in the turning position behind other rake wheels than in the side rake position (see FIG. 3). If you then lower the frame again, it comes to the in FIG. 3 position as a broad turner on the ground.

Claims (2)

Claims: ao 1. Device for the lateral displacement of crops lying on the ground with a frame and at least two rotatably mounted rake wheels on this frame, the axes of rotation of the rake wheels and thus the itech wheels themselves in the vertical direction tmovable -sind that they are attached together on a rigid support are, which is pivotable about a horizontal axis at least approximately parallel to the axes of rotation of the rake wheels and this common pivot axis of the rake wheels is vertically movable in relation to the frame 4 device, according to patent 1115 507, d ad.u rc hg £ indicates that the rigid carrier '(118) is connected to the hydraulically movable three-point coupling of a tractor by means of the pivot axis (116) , which is at least approximately parallel to the rake wheel axes (125), in such a way that the rake wheels (126) with the rigid carrier (118) carrying them is connected by means of the Three-point hitch can be lifted off the ground, and that the rake wheels in the raised position can only be swiveled axis. 2. Device according to claim 1, which can be converted into a second working position as a wide turner, characterized in that at least in this working position the rigid carrier (118) carrying the rake wheels is rotatable about a pivot axis extending parallel to the row of rake wheels relative to the three-point coupling.
