Abstract
Description
Die Erfindung bezieht sich auf eine Rüttelsteuerung für Land- und Baumaschinen.The This invention relates to a shaker control for agricultural and construction machinery.
Bei Land- und Baumaschinen, beispielsweise einem Frontlader in der Landwirtschaft, hat man, nicht immer, aber häufig das Problem anhaftenden Transportguts, beispielsweise das Haften bleiben von Silage bei einem Frontlader. Hier wünscht sich der Bediener, dass das anhaftende Gut möglichst rasch abgelöst wird. Mechanische Einrichtungen hierzu sind bekannt und werden in der Beschreibung des technischen Standes angegeben.at Agricultural and construction machinery, for example a front loader in agriculture, you have, not always, but often the problem of adhering cargo, such as sticking stay by silage at a front loader. Here the operator wishes that the attached material as soon as possible superseded becomes. Mechanical devices for this purpose are known and are in the description of the technical state indicated.
Selbsttätig wirkende Rüttelsteuerungen für Land- und Baumaschinen oder Bergwerksmaschinen sind aus der Patentliteratur bekannt.Self-acting Rüttelsteuerungen for land and construction machines or mining machines are from the patent literature known.
So
wird in der Patentschrift
Durch den nun in die zweite Zuleitung einschießenden Druck aus der ersten Zuleitung findet ein Druckabfall im Kolbenraum des Zylinders statt infolge des Druckabbaus in der ersten Zuleitung, verbunden mit einem sich erneut aufbauenden, aus der Pumpe gespeisten Druck in beiden Zuleitungen.By the now in the second supply einschießenden pressure from the first Supply line takes place a pressure drop in the piston chamber of the cylinder due to the pressure reduction in the first supply line, connected to a again building up, fed from the pump pressure in both Leads.
Der nun wieder vergrößerte Druck wirkt auf den Zylinder und gleichzeitig auf eine zweite Fläche des Wegeventils, wodurch das Wegeventil wieder schließt und die zweite Zuleitung zum Kolbenraum wieder entlastet. Die volle Funktion des Systems wird sichergestellt durch zusätzliche Rückschlagventile, einer Drossel vor der zweiten Steuerfläche des Wegeventils, unterschiedlich großer Steuerflächen des Wegeventils sowie einer Schließfeder am Wegeventil.Of the now again increased pressure acts on the cylinder and at the same time on a second surface of the cylinder Directional valve, whereby the directional valve closes again and the second supply to the piston chamber again relieved. The full function of the system is ensured by additional check valves, a throttle in front of the second control surface the directional control valve, different sized control surfaces of the directional control valve as well as a closing spring at the directional valve.
Der Rüttelvorgang wird also selbsttätig bei Erreichen eines bestimmten Drucks im Kolbenraum eingeleitet. Die Aufgabe eines vom Maschinenbediener vorgebbaren Rüttelns bei Land- und Baumaschinen, um beispielsweise anklebendes Transportgut vollständig von der Schaufel eines Vorderladers zu lösen, lässt sich mit einer derartigen Einrichtung nicht realisieren, da hier das Rütteln völlig unabhängig vom Druck in den Hydraulikzylindern zur Abstreifung anhaftenden Restguts stattfinden muss.Of the the shaking becomes self-sufficient initiated upon reaching a certain pressure in the piston chamber. The task of a predeterminable by the operator shaking at Agricultural and construction machinery, for example, adhering cargo completely from To solve the blade of a muzzle loader can be with such a Device not realize, since here the shaking completely independent of the pressure in the hydraulic cylinders for scraping adhering residual material must take place.

der Patentschrift
Die Aufgabe eines vom Maschinenbediener vorgebbaren Rüttelns bei Land- und Baumaschinen ist auch mit einer derartigen Rütteleinrichtung nur begrenzt lösbar. Dazu müsste erstens die Rütteleinrichtung so verändert werden, dass das Rütteln, das hier in der Endlage selbsttätig und vom Bediener nicht steuerbar ausgelöst wird, sich über das Einfügen einer zusätzlichen technischen Einrichtung abschalten lässt, denn nicht in jedem Falle wird Restgut haften bleiben. Zweitens müsste die Lage, bei der das Rütteln einsetzen soll, flexibel vorgegeben werden können, da das Rütteln nicht in jedem Falle in der Endlage stattfinden muss. Dazu müsste erheblicher technischer Aufwand betrieben werden.The Task of a predetermined by the machine operator shaking at Land and construction machinery is also with such a vibrating device only limited solvable. This would have to first, the vibrator so changed be that shaking, this automatically in the end position and is triggered by the operator uncontrollable, about the Insert an additional one switch off the technical equipment, because not in every case Restgut will stick. Second, the situation in which the Shake should use, can be given flexibly, since the shaking is not in any case must take place in the final position. This would have to be more significant technical effort to be operated.

Vorteil der beschriebenen Einrichtungen, insbesondere der Lösung nach
Patentschrift
Die Aufgabe der in den Patentansprüchen angegebenen Erfindung besteht nun darin, eine Rüttelsteuerung für Land- und Baumaschinen so auszuführen, dass sie folgende Anforderungen erfüllt:
- • Einfachste, kostengünstige Steuerung
- • Zuverlässiger Aufbau mit möglichst wenigen, mechanisch bewegten Teilen
- • Hoher Bedienkomfort durch vielfältige Möglichkeiten der Einflussnahme seitens des Bedieners
- • Simplest, cost-effective control
- • Reliable construction with as few mechanically moving parts as possible
- • High ease of use due to many possibilities of influence on the part of the operator
Die Verknüpfung des Vorteils des Schwingens mit Eigenfrequenz mechanischer Rütteleinrichtungen aus der aufgeführten Patentliteratur mit den Möglichkeiten einer komfortablen Beeinflussung des Rüttelvorgangs über elektronische Steuerungsmöglichkeiten wird realisiert mittels eines elektrisch steuerbaren Ventils, das über eine geeignete elektronische Steuerung das zu rüttelnde Bauteil in Schwingungen, insbesondere Resonanzschwingungen, versetzt gemäß der Patentansprüche.The shortcut the advantage of oscillating with natural frequency mechanical vibrators from the listed Patent literature with the possibilities a comfortable influencing the Rüttelvorgangs via electronic control options is realized by means of an electrically controllable valve, which has a suitable electronic control vibrates the component to be shaken, in particular resonance vibrations, offset according to the claims.
Aus der Schwingungslehre ist bekannt, dass die Amplitude fremderregter Schwingungen bei Resonanz an größten wird. Mithin sind bei gleichbleibender Frequenz die Beschleunigungen am größten, wenn die Amplitude maximal wird. Die Beschleunigung anhaftenden Schüttguts und damit die Ablösekraft für das Schüttgut wird damit maximal, wenn die Schwingungsbewegung am intensivsten ist.Out The vibrational theory is known that the amplitude of other excited Vibrations at resonance becomes largest. Thus, with constant frequency, the accelerations on biggest, though the amplitude becomes maximum. The acceleration adhering bulk material and so that the detachment force for the bulk becomes maximum when the vibrational motion is most intense is.
Ziel ist es daher, die Schwingungsbewegung möglichst intensiv zu gestalten, aber gleichzeitig den Aufwand hierfür geringstmöglich zu halten. Die Lösung des technischen Problems erfolgt gemäß den in den Patentansprüchen angegebenen Lösungen.aim It is therefore to make the vibrational motion as intense as possible, but at the same time keep the effort as low as possible. The solution of technical problem occurs in accordance with the claims specified solutions.
Unterstützend zur Umsetzung eines optimalen Rüttelvorgangs wird die zu rüttelnde Baugruppe so gestaltet, dass ihre schwingungsrelevanten Parameter, insbesondere die Steife der Aufhängung, optimal mit dem erregenden Ventil zusammenwirken. Insbesondere kann die relativ hohe Steife der Ölsäule auf der Stangenseite in Endlagennähe vermindert werden durch Verbinden der Stangenseite mit zusätzlicher Speicherkapazität für komprimiertes Öl, insbesondere bekannten hydraulischen Speichen wie beispielsweise Blasenspeichern. Es kann jedoch auch der Zylinder so ausgeführt werden, dass die zusätzliche Speichermöglichkeit für komprimiertes Öl im Zylinder integriert ist, beispielsweise mittels einem verlängerten Zylinderrohr mit Anschlag für die Endlage auf der Stangenseite.Supportive to Implementation of an optimal shaking process will be the one to shake Assembly designed so that its vibration-relevant parameters, especially the stiffness of the suspension, optimally interact with the exciting valve. In particular, can the relatively high stiffness of the oil column the rod side near the end be reduced by connecting the rod side with additional storage capacity for compressed oil, in particular known hydraulic spokes such as bladder accumulators. However, the cylinder can also be designed so that the additional memory option for compressed oil in the cylinder is integrated, for example by means of an extended Cylinder tube with stop for the end position on the rod side.
