Description
Die Erfindung bezieht sich auf ein Grabenziehgerät, das aus einem sägeartig ausgebildeten, in elliptische Schwingungen versetzten Grabewerkzeug besteht. Es ist insbesondere als Schlepperanbaugerät vorgesehen.The invention relates to a trenching device, which consists of a saw-like, elliptical Vibrations offset digging tool exists. It is particularly suitable as a tractor attachment intended.
Es sind Grabenziehgeräte bekannt, bei denen zur Verminderung der zur Fortbewegung der Arbeitswerkzeuge erforderlichen Zugkräfte die Grabewerkzeuge mittels Federwirkung, Kurbel und Kurbelschleife oder durch Kurbelstange und Exzenter in eine in vertikaler Ebene hin- und hergehende oder ellipsenartige Bewegung versetzt werden. Der Antrieb erfolgt von einem Laufrad des Gerätes, von einem Motor oder von der Zapfwelle eines Schleppers aus.Trenching devices are known in which to reduce the need to move the work tools necessary tensile forces the digging tools by means of spring action, crank and crank loop or by means of a connecting rod and eccentric in a reciprocating or in a vertical plane elliptical movement are offset. It is driven by an impeller of the device, by one Engine or from the PTO shaft of a tractor.
Diese Bauarten haben den Nachteil, daß sie einen erheblichen Werkstoffaufwand erfordern. Infolge des hohen Gewichtes dieser Geräte und der niedrigen Schwingungsfrequenz der Grabewerkzeuge ist eine wesentliche Verminderung der Zugkräfte nicht gewährleistet, aoThese types of construction have the disadvantage that they require a considerable amount of material. As a result of the the heavy weight of these devices and the low vibration frequency of the digging tools is one significant reduction in tensile forces not guaranteed, ao
Die vorliegende Erfindung vermeidet die oben angeführten Nachteile und bringt eine weitgehende Zugkraftverminderung. Die Erfindung besteht darin, daß die elliptischen Schwingungen des Grabewerkzeuges durch einen Frequenzumwandler über Magnete erzeugt werden. Dabei ist es zweckmäßig, daß die elliptischen Schwingungen des Grabewerkzeuges 50 bis 1000 Hz betragen und die Amplitude je nach Schwingungszahl verschieden groß ist.The present invention avoids the disadvantages mentioned above and brings about a substantial reduction in the pulling force. The invention consists in that the elliptical vibrations of the digging tool generated by a frequency converter via magnets. It is useful that the elliptical Vibrations of the digging tool are 50 to 1000 Hz and the amplitude depends on the number of vibrations is different in size.

In order to make this possible, the vibration carrier 3 is pivotably mounted on a stationary bolt 4. The elliptical vibrations of the digging tool 5 are generated by a frequency converting trenching device
