The invention relates to a haymaking machine with a tractor driven, Zinc wheel rotatable about a vertical axis, on the cylindrical surface of which is radially extending prongs in pairs one above the other on holders between an upper and a lower ring are arranged according to patent 1165 923.

In the haymaking machine according to the main patent, the tines are rigid and immovable the toothed wheel arranged. It has been found, however, that in various, with the haymaking machine operations that can be carried out according to the main patent, such as swath spreading, Windrowing, times, etc., difficulties arise when the crop has a different moisture content having. The invention is therefore based on the object of the main patent designed so that it is to be treated even with different moisture conditions The crop is working properly.

Based on the fact that the mode of operation of the haymaking machine according to the main patent depends among other things on the circumferential speed and the position of the tines, this will Task based on the principle of adjustment of Guide vanes solved in that the holder carrying the prongs is pivotable in the upper and lower ring mounted and each with an arm pointing to the central axis of the toothed wheel and an arm on this hinged handlebars with one arranged inside the upper ring and in on the upper one Ring provided guides are connected in the circumferential direction movable inner ring, so that when Turn the inner ring of all holders with the prongs in the same direction and around the same The amount are adjustable in angle.

The angular adjustability of tines, both individually and collectively, is also known per se in haymaking machines with revolving tine carriers. In a known haymaking machine with tines extending radially outward through a rim tape and angled tine ends, these are connected at their inner ends to a tine pivoting device which engages with a pinion in a rotatable and lockable ring gear. This adjustment device, which can also be replaced by a rotatable ring into which the inner, cranked prong ends extend, enables the prongs to pivot together about their radial axes. Other haymaking machines have a common angle haymaking machine

Adjustment of the tines is known, which is done via eccentric tine holders by changing the position of the eccentric he follows. While the last-mentioned Zinkenverstellvorrichtüng especially with three or more Tine holders require a high level of structural effort and primarily when their inclination is controlled Prongs can be used, the adjusting device according to the invention enables a common, Tine adjustment in the same direction and at the same angle with little construction effort and correspondingly low Manufacturing costs, whereby at the same time a

maintenance-free and operationally safe mode of operation is guaranteed.

In a further embodiment of the adjusting device according to the invention, one of the arms is extended and designed as a handle that is used to move the inner ring. The inner ring has advantageous in the area of one of the guides vertical holes and is by means of a through one in this guide provided vertical hole through the cotter pin or the like. In different positions lockable. This training enables tine adjustment in a short time and with a few Handles, so that an adjustment of the tine inclination with different humidity of each crop to be treated can be done easily and quickly by hand.

An embodiment of the subject matter of the invention is shown in the drawing. It shows

F i g. 1 is an elevation of the haymaking machine, seen from the rear of the tractor, F i g. 2 is a plan view of FIG. 1 and F i g. 3 and 4 two further plan views of FIG. 1 each with the end position of the tines.

The haymaking machine is at the rear on a tractor (not shown) by means of an adjustable Supporting beam 1 attached, as shown and described in detail in the main patent specification is. A vertical tubular sleeve 2, in which a shaft 3 is rotatable, is attached to the support beam 1 is stored. The shaft 3 carries a pulley 4 at its upper end and is driven by a belt driven by the tractor's PTO shaft. At its lower end, the shaft 3 has a Disc 5 on the one hand with struts 6 with an upper ring 7 and on the other hand with struts 8 with a lower tubular ring 9 is rigidly connected. When the shaft 3 is driven, the upper one therefore rotates Ring 7 and the lower tubular ring 9 around the axis of the shaft 3.

On the outer cylindrical surface, which is through the upper ring 7 and the lower tubular ring 9 is formed, holders 10 are attached, which carry the prongs 11 extending radially outward. The prongs 11 are expediently attached in pairs vertically one above the other to the holders 10 and consist of prongs which are known per se and connected by helical spring windings.

The holder 10 for the prongs 11 expediently consist of an approximately L-shaped bent flat iron; the horizontal L-legs 10 'point inwards and are on the lower tubular ring 9 by means Bolt 12 rotatably mounted and fastened. In addition, the holders 10 are by means of a horizontal arm 13 rotatably mounted on the upper ring 7. The arms 13 extend at the bottom of the upper one Ring 7 under this through a piece inward towards the central axis of the shaft 3. To the inner ends of the arms 13 are hinged at point 14 handlebars 15, the other end in the Point 16 are connected in an articulated manner to an inner ring 17 which is arranged within the upper ring 7 is. The inner ring 17 is in guides 18 attached to the upper ring 7 on the top and bottom held and movable. In the area of one of the top and bottom pairs arranged on the top ring 7 Guides 18, for example the guide 18 ', the inner ring is provided with a number of holes 19, and the guide 18 'is also pierced vertically, so that the inner ring 17 by means of a Cotter pin 20 or the like with the upper ring 7 in a position determined by the bores 19 can be connected and locked. One of the arms 13, expediently the one closest to the guide 18 ' Arm 13 'is extended inward and designed as a handle.

The prongs 11 are adjusted when the device is at a standstill after removing the split pin 20 by moving the handle 13 'into one of the positions shown in FIG. 2, 3 and 4 positions shown. When the handle 13 'is moved, the inner ring 17 is rotated relative to the upper ring 7 and the lower tubular ring 9 via the handlebar 15', so that all the holders 10 via the handlebars 15 attached to the inner ring 17, which are connected to the arms 13, be moved. The tines 11 can thus be adjusted jointly with respect to the radial line of the tine wheel at a certain angle, either, as in FIG. 3 shown, in the direction of the direction of rotation indicated by the arrow α or opposite to this.
