Description
Es sind landwirtschaftliche Maschinen bekannt geworden, deren Arbeitswerkzeuge durch Druckluft betrieben werden. Die Druckluft wird hier durch einen von einem besonderen Motor angetriebenen Kompressor erzeugt. Bei dieser Anordnung übertragen die Achsen des Fahrzeuges — wenn man von der Überwindung der eigentlichen Fahrwiderstände absieht — keine Arbeit.Agricultural machines have become known, their work tools operated by compressed air. The compressed air is here by one of a special kind Motor driven compressor generated. With this arrangement, the axles of the vehicle transmit - if one of the No work to overcome the actual driving resistance.
An solchen Maschinen jedoch, die von Tieren oder Zugmaschinen gezogen werden, und die keinen besonderen Motor zum Antrieb der Werkzeuge enthalten, müssen die Fahrzeugachsen notwendigerweise auch die gesamte für den Betrieb der Werkzeuge nötige Arbeit übertragen. Diese Arbeit, die letzten Endes vom Zugtier oder vom Traktor hergegeben werden muß, wird an der gezogenen Maschine vom Umfang der Räder abgenammen, die demnach gegenüber dem Erdboden genügend Reibungswiderstand aufweisen müssen.However, on such machines that are pulled by animals or tractors, and which do not contain a special motor to drive the tools, the vehicle axles must necessarily also transfer all of the work required to operate the tools. This work, the last End must be given by the draft animal or the tractor, is sampled on the pulled machine from the circumference of the wheels, which must therefore have sufficient frictional resistance against the ground.
Als Folge des meistens recht rohen Antriebes der Werkzeuge durch einfache Maschinenelemente (Nocken, Daumen, Steuerscheiben usw.), und falls insbesondere nur verhältnismäßig wenige Arbeitsspiele je Radumdrehung erforderlich sind, ergeben sich solche hohen Spitzenbelastungen an Arbeit, daß der Reibungswiderstand zwischen Radumfang und Boden überschritten und die Maschine zum Rutschen gebracht wird.As a result of the mostly quite crude drive of the tools by simple machine elements (Cams, thumbs, control disks, etc.), and if in particular only relatively few work cycles per wheel revolution are required, there are such high peak loads of work that the frictional resistance between the wheel circumference and the floor is exceeded and the machine is made to slide.
Zur Abwendung dieses Übelstandes sieht die vorliegende Erfindung die Zwischenschaltung einer an sich bekannten Drucklufterzeugungsanlage zwischen Fahrzeugachse und Werkzeug vor.To avert this disadvantage, the present invention provides the interposition a known compressed air generation system between the vehicle axle and the tool.
Bei genügend hoher Drehzahl des kleinen Kompressors wird — bezogen auf den Radumfang — die stoßweise Abnahme der Arbeit in eine ununterbrochene von mittlerer Höhe umgewandelt. Mit anderen Worten: Das Diagramm der Arbeitsentnahme, bezogen auf den Radumfang, welches bisher verschiedene hohe Spitzen aufwies, wird in ein Rechteck umgewandelt. Die Abnahme beliebig hoher und unregelmäßiger Arbeitsstöße geschieht nunmehr aus dem — die Wirkung eines Kraftsammlers übernehmenden — Luftbehälter der Anlage.If the speed of the small compressor is high enough, - based on the wheel circumference - the intermittent decrease of the work in a continuous of medium height converted. In other words, the diagram of the extraction of work relative to the The wheel circumference, which previously had different high peaks, is converted into a rectangle. The decrease of arbitrarily high and irregular work shocks now happens from the - the effect of a force collector receiving - air tank of the system.
