Description

Haymaking machine

The invention relates to a sole dragged Haymaking machine with one rigid cross member and several side by side with respect to the direction of travel arranged, essentially rotating about vertical axes, PTO shaft driven tine rotors, their Ground clearance is kept constant by their assigned jockey wheels.

There are haymaking machines of this type known at where the essentially vertical tine gyro axes are attached to a rigid cross member · Two of these tine swivel arms are supported on one opposite each other the cross member from the non-adjustable carrier wheel, The distance between the corresponding tine rotors and the cross member is also not adjustable · The distance the rest of the tine top from the cross member is through assigned to them with variable distance from the cross member? changeable, whereby the tine circles

be when driving over the jockey wheels over a bump in the floor be raised or lowered accordingly.

The haymaking machines of the known type have the disadvantage that the storage of the tine rotors, depending on whether they are arranged over a feeler or support wheel, is designed differently, which means expensive storage and thus means more expensive manufacturing during production. In addition, the haymaking machine must be known Construction for transferring from the operating position to their transport position, in which their effective Width complies with traffic regulations, can be switched to two separate transport wheels, which is time-consuming Handouts is connected.

These disadvantages are avoided by the subject matter of the invention, in which the cross member of the drive parts, bearing housings and feeler wheels of the tine rotors are arranged separately and provided with their own support wheels * and with reference on the direction of travel in operation in front of the drive parts, bearing housings and feeler wheels of the tine rotors. This makes it possible to completely remove the drive parts, bearing housings and feeler wheels of the tine rotors to train in the same way. The units consisting of the bearing housing, jockey wheel and tine rotor axis for loading

each of a tine rotor are according to the invention A pair of parallel links each are connected to the main girder, the main girder being within the transverse girder rotatable but not displaceable * is arranged and aeine Ends protrude from the cross member · Through these parallel links is a vertical movement of each tine spinning top and the units depending on its storage alone of uneven floors regardless of the movement of another unit and movement of the cross member possible, whereby the tine rotor and the unit for its storage always maintain the preset inclination.

Due to the pivoting mounting of the support wheels of the cross member about vertical axes and a pivoting option the treadwheels around their associated tine gyro axis the haymaking machine can be freestanding transversely to the working direction without time-consuming adjustment of the cross member can be moved · A conversion of the haymaking machine from the operating position to the Transportpositionι in which the effective width of the haymaking machine corresponds to the Verkehrsvorsohrifte, so only requires attaching a 4-way drawbar on the narrow side of the machine instead of on the cross member The desired ground clearance of the spring tine ends of the tine

I is a main beam 5 rotatable, but not displaceable arranged, the ends 6 of the cross member 1 over ten. On the main beam 6 are one-sided at right angles striving Lasohen 7 at a distance from each other attached · These tabs 7 extend preferably in a substantially vertical direction upwards. the Lasohen 7 carry above the "main beam 5 holes 8, 9 for the rotatable mounting of two parallel links 10, 11. The connecting line of the bores 8, 9 intersects the longitudinal axis of the tubular cross member 1 · The dem Main beam 5 facing away from the ends of the parallel link 10,

The carrying wheel 20 and the fork 21 of each tine ice 19 are in the Transport position with the tine rotor axis 22 free pivotally connected, while in the operating position shown in FIG. 3, for example, by a plug can be locked on the tine rotor lug. On the Zinkenkreiselaohsen 22 they are known in and of themselves Way as Hohrwellen 23 designed drive shafts for the rotary drive of the tine rotor 19 rotatably mounted. Of this type with a rotary drive and jockey wheels

the tine rotors you can see is at the haymaking machine according to the invention, any number, preferably an even number, is provided and in the manner described with reference to the broad side attached to the main beam next to each other via a pair of parallel links. Of the The rotary drive for the tine rotors is via a connected to the tractor PTO shaft (not shown) Cardan shaft 24 introduced into an angular gear 25, which is fastened to cross member 1 via a carrier 26.

The output shafts 27 »28 of the angular gear 25 are essentially in a line of alignment in the rest position with the axes of rotation of the bevel gears 17 · From the bevel gear 25 the rotary drive movement to the bevel gears 17 »18 of the tine rotors 19 is known per se. ! ter way transmitted via propeller shafts 29 (Fig. 1). To the Any setting of the floor distance h (Fig. 2) of the spring tines 30 of the tine rotor 19, the main beam 5 in the cross member 1 can be rotated by an amount. By such a rotation, the tabs 7 are pivoted through an angular amount. By the parallel link 10, 11 a pivoting by the same angular amount is transmitted to the bearing housing 16 of each tine rotor, at the same time each tine gyro axis 22 is inclined by the same angular amount. This discontinued

Inclination maintains each tine rotary eye 22, even if the associated jockey wheel 20 drives over an unevenness in the ground and the zinc circles ^. including its storage dodges freely near the top. As an adjustment device for The threaded spindle is used to rotate the main beam 5 in the cross beam 1 31 with the crank 32, on the one hand on one of the main beam 5 extending downwards Extension 39 of a bracket 7 via a spindle nut 33 at 34 and on the other hand via the axial bearing 35 on the pivot bearing firmly connected to the cross member 1 3 is stored. ■ ''.

For the transport position of the haymaking machine the mobility of the parallel link connection 10 »11 is disabled and the tine rotor axis 22 in brought an essentially vertical position (3? ig. 3). For this purpose, a bore 36 is attached to a parallel link 11 and a bracket 37 is attached to a bracket 7, the at its free end with a hole of the same size as. the bore 36 is provided. With essentially " vertical position djsr tabs 7 falls the axis of the hole the bore 36 with the bore at the end of the boom 37 in. One line of flight. Then, by means of a plug 38, this link 11 can be locked against the tab 7 connected to the bracket 37. It
