Abstract

The tine attachments can pivot on a roughly tangential axis. A weight when in a non-operation position counteracts the weight of the tine. Alternatively, a plate spring prevents the tine from flapping back into place while being transported. Alternatively, magnetic attachment pieces or balls and pins hold the tines in a transporting position. The various pieces keep the tines in a high, inward pivoting position, when the wheel is not in operation. When the wheel begins to rotate, the resistance of these mechanical pieces is automatically overcome by centrifugal force, so that the tines assume a working position.

Description

H e u w e r b u n g s m a s c h i n e Die Neuerung bezieht sich auf eine landwirtschaftliche Maschine, insbesondere Heumaschine, zur Bearbeitung von Heu, Strch und ähnlichen Erntegütern mit mindestens eineem umlaufenden Rad, welches über den Umfang verteilte Arbeitsglieder@, wie z. P. Zinken o. dergl. besitzt und um eine etwa vertikal@ Achse rotiert, welche nach vorne zum Boden hin geneigt ist, Die Anfgabe dieser Maschine ist es, sowohl Heu, Gras, Stroh und anderes Erntegut auseinanderzustreuen, als auch zu sauberen Schwaden zusammenzulegen. H e u w e r b u n g s m a s c h i n e The innovation relates to an agricultural machine, in particular a hay machine, for processing Hay, stork and similar crops with at least one rotating wheel, which working links @ distributed over the circumference, such as P. tines o. The like. Has and rotates around an approximately vertical @ axis, which is inclined forward towards the ground, The purpose of this machine is to handle both hay, grass, straw and other crops to spread them apart as well as to fold them into clean swaths.

Es sind Maschinen bekannt, deren Zinken bei Stillstand des Rechrades selbsttätig durch Federn vom Boden in Transportstellung gehoben werden. ner Nachteil dieser Maschinen ist, daß während der Arbeit der Federdruck durch die Zentrifugalkraft ständig überwunden werden muß. und daher eine bestimmte Drehzahl der Kreisel bei der Arbeit nicht unterschritten werden darf. Insbesondere bei bereits angetrocknetem Heu ist dies nachteilig.There are machines known, the tines of which when the rake wheel is at a standstill be lifted automatically from the floor into transport position by springs. a disadvantage of these machines is that while working the spring pressure is due to centrifugal force constantly has to be overcome. and therefore a certain number of revolutions of the gyroscope the work must not be undercut. Especially with things that have already dried on Hay this is disadvantageous.

Es sind weiterhin Maschinen bekannt, deren Zinkenarme von Tiand bei Stillstand des Rechrades in Transportstellung hochgeklarpt-- und in dieser Stellung verriegelt werden0 Der Nachteil dieser Ausführung ist, daß bei Inbetriebnahme der Maschine die Zinkenarme wieder von Hand gelost werden müssen.There are also machines known whose tine arms from Tiand at The rake wheel has come to a standstill in the transport position - and in this position are locked0 The disadvantage of this version is that when the Machine the tine arms have to be loosened again by hand.

Neuerungsgemäß wird die Aufgabe, eine geringere Transportbreite zu erhalten, dadurch gelöst, daß bei Stillstand desä Rades die Arbeitsglieden um etwa tangentiale Achsen hochgeschwenkt werden und in dieser Stellung.von mechanischen Elementen gehalten werden. Bei beginnender Rotation des Rades wird der Widerstand dieser machanischen Elemente selbsttätig durch die Zentrifugalkraft überwunden, sodaß die Arbeitsglieder ihre Wirkstellung einnehmen können.According to the innovation, the task is to reduce the transport width obtained, solved in that when the wheel comes to a standstill, the working links by about tangential axes are swiveled up and in this position. by mechanical Elements are held. When the wheel begins to rotate, the resistance increases of these mechanical elements automatically through centrifugal force overcome so that the working members can take their active position.

Die Meuerung wird an Hand der Zeichnung einiger Ausführungsbeispiele näher erläutert : Fig. 1/ Die Seitenansicht eines Ausführungsbeispieles.The mine is based on the drawing of some embodiments explained in more detail: Fig. 1 / The side view of an embodiment.

Fig. 2/ Die Draufsicht eines Ausführungsbeispieles.Fig. 2 / The top view of an embodiment.

Fig. 3/ Die Seitenansicht der schwenkbaren Zinkenhalterung als weiteres Ausführungsbeispiel.Fig. 3 / The side view of the pivotable tine holder as another Embodiment.

In den Ausführungsbeispielen sind en der Kreiselrad (1), welches um die etwa vertikale Achse 93) rotiert, die Arbeitsglieder (2) angebracht. Die Kreiselräder drehen in der Richtung (15).In the exemplary embodiments, the impeller (1), which is around the approximately vertical axis 93) rotates, the working members (2) attached. The gyroscopes turn in direction (15).

Die Zinkenhalterung (17) ist um die etwa tangentiale Achse (16) schwenkbar. In einer Ausführungsform wirkt das Gewicht (31) in Ruhestellung des Zinkens (2") dem Gewicht des Zinkens (2") entgegen.The prong holder (17) can be pivoted about the approximately tangential axis (16). In one embodiment, the weight (31) acts in the rest position of the tine (2 ") against the weight of the tine (2 ").

In einer weiteren Ausführungsform verhindert die Blattfeder (32) ein Zurückklappen des Zinkens (2") in Stellung (2) während des Transportes.In a further embodiment, the leaf spring (32) prevents a Fold the tine (2 ") back into position (2) during transport.

Ebenso denkbar sind federbelastete Kugeln oder Stifte, die seitlich z.B. auf die Zinkenhalterung (17) in Transportstellung einwirken, um die Zinken in dieser Transportstellung zu haltens (Zeichnerisch nicht dargestellt) Eine weitere Ausführungsform sind magnetische Halteelemente, die die Zinken (2") in der Transportstellung halten. (Zeichnerisch nich dargestellt.)Also conceivable are spring-loaded balls or pins that are laterally e.g. act on the tine holder (17) in the transport position to move the tines to hold in this transport position (not shown in the drawing) Another Embodiment are magnetic holding elements that the prongs (2 ") in the transport position keep. (Not shown in the drawing.)
