Description

Das Patent 429 621 hat eine Hackmaschine zum Gegenstand1, bei der der Gespannzug unmittelbar an dem um die hintere Achse ausschwingbaren Hackrahmen angreift. Dabei ist durch Höher- und Tieferlegen des Angriffspunktes der Zugkraft ein Be- und Entlasten bzw. ein Ausheben des Hackrahmens möglich. In der Praxis hat sich herausgestellt, daß Maschinen, bei denen die Gespannzugkraft unmittelbar auf den Hackrahmen wirkt, infolge der Schwankungen der Zugkraft, hervorgerufen durch den ungleichen Gang der Zugtiere, besonders in bergigem Gelände, eine ungleichmäßige Hackarbeit liefern und das Ausheben infolge der verhältnismäßig geringen Kraft der Zugtiere schwierig vonstatten geht. Da es in der Praxis von allergrößtem Wert ist, daß der Hackrahmen mit einer möglichst konstanten Belastung arbeitet und bei vollständigem Nachlassen der Zugkraft der Tiere, z. B. beim Bergabhacken, noch mit einer gewissen Belastung mit seinen Messern im Boden gehalten wird, wird gemäß der Erfindung die Zugstange« (Abb. 1) mit einer Feder α versehen und derart im Punkte b gegen das Hackmaschinengestell abgestützt, daß durch die Zugfeder α auch bei fehlendem Gespannzug ein gewisser Zug auf den Hackrahmen / ausgeübt wird. Beim Anziehen der Zugtiere wird also in dem Abstützungspunkt b sich die Zugstange η vom Gestell abheben. Auf diese Weise läßt sich eine viel gleichmäßigere Hackarbeit erzielen.The patent 429 621 has a chopping machine as subject 1 , in which the trailer pull engages directly on the chopping frame that can swing out about the rear axis. By raising and lowering the point of application of the tensile force, loading and unloading or lifting of the hoe frame is possible. In practice, it has been found that machines in which the pulling force acts directly on the hoe frame, due to the fluctuations in the pulling force caused by the uneven gait of the draft animals, especially in mountainous terrain, provide uneven hoeing work and the excavation due to the relatively low level Difficult to proceed with the strength of draft animals. Since it is of the utmost value in practice that the hoe frame works with as constant a load as possible and when the pulling force of the animals, e.g. B. when chopping downhill, is still held with a certain load with his knives in the ground, according to the invention, the pull rod «(Fig. 1) is provided with a spring α and supported in point b against the chopping machine frame that by the tension spring α a certain pull is exerted on the hoe frame / even if there is no trailer pull. When the draft animals are attracted, the pull rod η will rise from the frame at the support point b. In this way, a much more even chopping work can be achieved.

Ferner wird durch Führung des hinteren Endpunktes der Zugstange η mittels Rolle u auf einem Kurvenbügel, der mit dem unteren Ende an der Zahnstange des Hackrahmens und mit dem oberen mittels einer Verbindungsstange am Steuerhebel angelenkt ist. gegenüber dem Hauptpatent eine wesentliche Verbesserung erzielt, weil, wie dies an sich bekannt ist, bei Bewegung des Steuerhebels nach oben die Rolle der Zugstange auf der Kurvenbahn entlangrollen kann (Abb. 2 und 2a), so daß ein wirksames Aushebedrehmoment auf den Hackrahmen f ausgeübt wird. Beim Anheben der Steuerstange wird der Hackrahmen allerdings nicht gleich angehoben. Die Steuerstange ist vielmehr um einen geringen Winkel um den Punkt r drehbar, d. h. sie hat toten Gang zum Vorlegen des Kurvenbügels, wodurch die Rolle u aus der unteren Rast springt.Furthermore, by guiding the rear end point of the tie rod η by means of a roller u on a curved bracket, the lower end of which is hinged to the rack of the chopping frame and the upper end to the control lever by means of a connecting rod. achieved a substantial improvement over the main patent because, as is known per se, when the control lever is moved upwards, the roller of the pull rod can roll along the cam track (Fig. 2 and 2a), so that an effective lifting torque is exerted on the hoe frame f will. However, when the control rod is raised, the hoe frame is not raised immediately. Rather, the control rod can be rotated through a small angle around point r, ie it has a dead gear to advance the curve bracket, whereby the roller u jumps out of the lower detent.
