Description
Die Arbeiten zur Herstellung von Entwässerungsgräben werden immer noch zum großen Teil durch kostspielige zeitraubende Handarbeit geleistet. Es sind bereits viele Ausführungsformen für eine Maschine zum Ausheben "von Entwässerungsgräben auf dem Markt gezeigt worden, aber einwandfreie praktische Arbeit haben diese Maschinen bis heute kaum geleistet. Es ist daher verständlich, wenn immer wieder neue Verbesserungsvorschlage gekommen sind.Work on the creation of drainage ditches is still going on in large part done by costly, time-consuming manual labor. There are already many embodiments for a machine for digging "drainage ditches" has been shown on the market, but To this day, these machines have hardly done flawless practical work. It is therefore understandable when there are always new suggestions for improvement.
Die Zeichnung zeigt ein Ausführungsbeispiel der Baggerfräse gemäß der Erfindung.The drawing shows an embodiment of the backhoe according to the invention.
Abb. ι zeigt die Baggerfräse in schematischem Querschnitt mit einer in zwei Lagern waagerecht gestützten Antriebswelle 1, deren Durchmesser durch eine fest mit der Welle verbundenen Trommel 2 vergrößert ist. An der zylindrischen Wandung der Trommel 2 sind durch Stützbleche verlängert in beliebiger Anzahl und in gleichen Abständen hintereinander auswechselbar die Baggereimer 3 angebracht. Jeder Baggereimer 3, ist versehen mit einem Schneidmesser 4, einem schneidartig wirkenden Fräser und Räumer 5 und mit einem Auswurffenster 6. Die Fräser und Räumer 5 bewirken, daß den Baggereimer 3 hinderndes Wurzelwerk zerschnitten und kleine Steine geräumt werden. Das Auswurffenster 6 gibt den Weg frei zur Entleerung des Baggereimers 3.Fig. Ι shows the excavator cutter in a schematic cross section with a drive shaft 1 supported horizontally in two bearings, the diameter of which is enlarged by a drum 2 firmly connected to the shaft. On the cylindrical wall of the drum 2 , the bucket 3 are extended by supporting plates in any number and at the same intervals, replaceable one behind the other. Each bucket 3 is provided with a cutting knife 4, a cutting-like cutter and scraper 5 and with an ejection window 6. The cutter and scraper 5 cause the bucket 3 to cut up obstructive roots and remove small stones. The ejection window 6 clears the way for emptying the bucket 3.
Abb. 2 zeigt einen einzelnen kompletten Baggereimer 3 in räumlicher Darstellung.Fig. 2 shows a single complete excavator bucket 3 in a spatial representation.
Der Arbeitsgang der Baggerfräse ist kurz folgender: Die in Pfeilrichtung α rotierende Baggerfräse wird durch eine Vorrichtung auf die gewünschte Tiefe in den Boden gesenkt, die am Baggereimer 3 angebrachten Fräsen und Räumer 5 leisten hierbei die Vorarbeit für das Schneidmesser 4. Nach Erreichung der gewünschten Tiefe beginnt die Vorwärtsbewegung in Pfeilrichtung b- Die von dem Baggereimer 3 aufgenommene Erde wird durch die Zentrifugalkraft zur gewollten Zeit aus dem Auswurffenster 6 heraus befördert. Die gewollte Entleerung des Baggereimers 3 wird reguliert durch ein verstellbares Gleitblech 7.The operation of the excavator cutter is as follows: The excavator cutter rotating in the direction of the arrow α is lowered into the ground by a device to the desired depth, the cutters and scrapers 5 attached to the excavator bucket 3 do the preparatory work for the cutting knife 4. After the desired depth has been reached The forward movement begins in the direction of the arrow b- The earth picked up by the bucket 3 is transported out of the ejection window 6 at the desired time by the centrifugal force. The intended emptying of the bucket 3 is regulated by an adjustable sliding plate 7.
Die Konstruktion dieser Baggerfräse erlaubt den Vorwärts- und Rückwärtseinsatz je nach der durch die Bodenbeschaffenheit bedingten Erdbewegung von unten nach oben bzw. von oben nach unten durch Umstellung des Baggereimers 3.The construction of this backhoe allows it to be used forwards and backwards depending on the through Earth movement from bottom to top or from top to bottom due to the nature of the soil by moving the bucket 3.
Das Profil der auszuhebenden Gräben wird durch die Größe des Baggereimers 3 und die eingestellte Tiefe bestimmt. Als Antriebskraft kann jede in der Landwirtschaft übliche Motorenkraft in Anwendung kommen.The profile of the trenches to be excavated is determined by the size of the bucket 3 and the set Determined depth. Any motor power customary in agriculture can be used as the driving force come.
