Description
<Desc/Clms Page number 1>
Rüttelegge
EMI1.1
<Desc/Clms Page number 2>
Einspannstellen wird eine elastische Lagerung--10--verwendet, welche etwa auf Befestigungsbolzen --11-- aufgefädelt und von einer Mantellasche--12--umhüllt werden, an welcher die Blattfedern --8-- eingespannt werden, wie dies in Fig. 4a und 4b dargestellt ist. Dadurch wird ein Teil der Pendelbewegung vom elastischen Material der elastischen Lagerung --10-- aufgenommen und die Knickstelle der Pendelbewegung der Blattfedern auf einen grösseren Bereich der Längsabmessung derselben verteilt.
Gemäss Fig. 5 ist zum gleichen Zweck der Befreiung der Blattfedern von zerstörenden
EMI2.1
Mantellasche--12--bügeiförmig--8-- eingespannt ist. Da durch die Elastizität der elastischen Lager--10--ein Teil der Biegungsbewegung aufgenommen wird, ist auch bei dieser Konstruktion der Knickquerschnitt auf eine grössere Länge der Blattfedern --8-- verteilt.
EMI2.2
einfachster Weise mehr als zwei Eggenbalken gegenläufig gegeneinander angetrieben werden, während durch die vertikale Anordnung der Blattfedern in ihrer Längsrichtung die Baulänge der Egge wesentlich verkürzt werden kann, so dass in gemeinsamem Schleppzug auch weitere Folgegeräte an die Egge angehängt werden können und deren Führung durch die Verkürzung der Eggenlänge erleichtert wird.
PATENTANSPRÜCHE :
1. Rüttelegge mit Kurbelantrieb der Eggenbalken, die auf dem mit der Dreipunkt-Hydraulik verbundenen Eggenrahmen aufgehängt sind und die Aufhängung der Eggenbalken durch, am Eggenrahmen lotrecht eingespannte Blattfedern erfolgt, nach Patent Nr. 281483, da dur c h ge- kennzeichnet, dass die Blattfedern (8) in ihrer Längsrichtung vertikal hängen.

EMI1.1
<Desc / Clms Page number 2>
Clamping points, an elastic mounting - 10 - is used, which is threaded onto fastening bolts - 11 - and covered by a jacket strap - 12 - on which the leaf springs - 8 - are clamped, as shown in Fig 4a and 4b is shown. As a result, part of the pendulum movement is absorbed by the elastic material of the elastic bearing --10 - and the kink of the pendulum movement of the leaf springs is distributed over a larger area of the longitudinal dimension of the same.
According to Fig. 5 is for the same purpose of freeing the leaf springs from destructive
EMI2.1
Shell flap - 12 - bow-shaped - 8-- is clamped. Since part of the bending movement is absorbed by the elasticity of the elastic bearings - 10 -, the buckling cross-section is also distributed over a greater length of the leaf springs --8-- in this construction.
EMI2.2
In the simplest way, more than two harrow bars can be driven in opposite directions, while the vertical arrangement of the leaf springs in their longitudinal direction can significantly shorten the overall length of the harrow, so that further follow-up devices can be attached to the harrow in a common tow and their guidance through the shortening the harrow length is made easier.
PATENT CLAIMS:
1. Vibrating harrow with crank drive of the harrow bars, which are suspended on the harrow frame connected to the three-point hydraulic system and the harrow bars are suspended by leaf springs clamped vertically on the harrow frame, according to Patent No. 281483, as it is indicated by the leaf springs (8) Hang vertically in its lengthwise direction.
