Abstract
Description
Das Führen von Arbeitswerkzeugen in einer angestrebten Linie und Arbeitstiefe ist vor allem in der Landmaschinentechnik in vielen Arbeitsprozessen ein weit verbreitetes Grunderfordernis. Insbesondere bei mechanischen Hackgeräten ist diese Funktion möglichst genau und mit einfachen technischen Hilfsmitteln robust und kostengünstig zu realisieren.The management of work tools in a targeted line and depth of work is especially in the Agricultural machinery technology is widely used in many work processes Basic requirement. Especially with mechanical chippers this function if possible accurate and robust with simple technical aids and inexpensive realize.
Hier hat sich seit Jahrzehnten das
Prinzip des Parallelogramms mit zwei oder vier Gelenkarmen und der
entsprechenden Anzahl von Gleitlagerstellen bewährt, dessen vertikale Führung mittels
einer verstellbaren Laufrolle gewährleistet wird. In der
Die Nutzung einer Laufrolle hat bei leichten und weichen Böden ihre Grenzen, während gegenteilige Bedingungen wiederum stabile, passgenaue und schmierbare Lagerstellen erfordern. So einfach eine solche Konstruktion auch ist, so anfällig ist sie auch gegen Verschleiß und zieht wegen der vielen Einzelteile in diesem Falle entsprechend hohe Reparaturkosten nach sich.The use of a roller has light and soft floors their limits while contrary conditions in turn stable, precise and lubricable Require bearings. It's as simple as that is so vulnerable it is also against wear and tear pulls due to the many individual parts in this case high repair costs.
Immerhin können je Hackelement einschließlich der Laufrolle bis zu 10 Lagerbuchsen zu warten oder zu wechseln sein. Für eine 3 m-Getreidehacke sind das 190 Teile! Hackgeräte mit 6 m, 9 m oder 12 m Arbeitsbreite sind nicht mehr unüblich. Hier summieren sich darüber hinaus die etwa bei 10 kg liegenden Gewichte der einzelnen Hackeinheiten so, dass zusätzliche Stützräder für den Gesamtrahmen und dessen Verstärkung erforderlich werden.After all, each chopping element including the Roller up to 10 bushings to be maintained or replaced. For one 3 m grain hoe is 190 pieces! Choppers with a working width of 6 m, 9 m or 12 m are no longer unusual. Here add up about it the weights of the individual chopping units, which are around 10 kg, that additional Jockey wheels for the entire frame and its reinforcement become necessary.
Auch funktionell aus der Sicht des Arbeitswerkzeuges ist die straffe Lagerung kritisch zu sehen. Hackwerkzeuge werden auch bei Frontanbau des Gerätes praktisch gezogen und folgen daher der vorgegebenen Fahrtrichtung automatisch.Functionally from the point of view of the Working tools, the tight storage is critical. Hoeing tools are practically pulled and follow when the device is attached to the front hence the given direction of travel automatically.
Eine geringe Längs- und Querbewegung des Hackmessers ist für seine verbesserte Wirkung bei verhärteten Bodenverhältnissen sogar gewünscht. Dieser Vibrationseffekt wird dann durch federnd verbundene Werkzeuge erzeugt.A slight longitudinal and transverse movement of the chopping knife is for its improved effect in hardened soil conditions even wanted. This Vibrating effect is then generated by spring-connected tools.
Die große Pendelmöglichkeit der Parallelogramme in vertikaler Richtung ist konstruktiv gegeben und nicht nur der erforderlichen Bodenanpassung geschuldet. Wegen der Arbeit in einem Saatbett würde eine Auslenkung von 10 cm in beiden Richtungen auch im Hindernisfall genügen.The large pendulum possibility of the parallelograms in the vertical direction is constructive and not just that due ground adaptation. Because of working in one Seed bed would a deflection of 10 cm in both directions even in the event of an obstacle suffice.
Eine Verbesserung des beschriebenen
Zustandes streben so genannte Teleskopschare an. Hier werden, wie
beispielsweise in
Ziel einer Weiterentwicklung muss es daher sein, die Führung eines Hackmessers in einer Hackmaschine sowohl in Arbeitsrichtung als auch in horizontaler und vertikaler Ebene konstruktiv so zu gestalten, dass sie mit einer möglichst geringen Anzahl anspruchsloser und wartungsarmer Lagerstellen, einfachen und kostengünstigen Bauteilen und Materialien unter Beibehaltung der bekannten Wirkungsweise realisiert werden kann und hierbei das Gewicht einer auf die Kulturreihe bezogenen Hackeinheit deutlich reduziert.The goal of further development must therefore it be the lead a chopping knife in a chopping machine both in the working direction as well as in the horizontal and vertical planes design that with a possible low number of undemanding and low-maintenance bearings, simple and inexpensive Components and materials while maintaining the known mode of operation can be realized and the weight of one on the cultural series related chopping unit significantly reduced.
Erfindungsgemäß wird diese Zielstellung durch eine konstruktive Trennung der in bisher bekannten Lösungen üblichen Aufnahme von Zug- und Druckkräften sowie Drehmomenten in allen Einzelbauteilen in reine zug- und reine druckbelastete Bauteile erreicht, die vorteilhaft als Zugseil und Druckfeder minimalste Materialaufwendungen und anspruchslose Lager- und Verbindungsstellen des durch die spezielle Formung der Blattfeder nunmehr gleitend am Boden geführten Hackelementes erfordern.According to the invention, this objective is achieved by a constructive separation of the usual in previously known solutions Absorption of tensile and compressive forces as well as torques in all individual components in pure tensile and pure Compressed components reached, which is advantageous as a pull rope and Minimal material expenditure and undemanding storage and joints of the special shape of the leaf spring now sliding on the floor Require chopping element.
