Description

Die Erfindung betrifft eine Vorrichtung zur Pflege von Grünanlagen gemäß den Patentansprüchen.The invention relates to a device for maintaining green spaces according to the claims.

Es handelt sich vor allem um eine runde, konkave Schneidklinge, aus entsprechend behandeltem Stahl, mit welcher eine Maschine zur Beseitigung von Gestrüpp und Unterholz in WäJcern, Parks und Gärten bestückt wird . Auch können die Ränder von Wegen, insbesondere die Rasenkanten, mit einer solchen Vorrichtung beschnitten werden. Auch Hecken können mit einem solchen Gerät beschnitten werden.It is mainly a round, concave cutting blade, Made of appropriately treated steel, with which a machine for clearing undergrowth and undergrowth in weirs, parks and gardens. Also can the edges of paths, in particular the edges of the lawn, are trimmed with such a device. Even hedges can be trimmed with such a device.

Die Schneidklinge gemäß der Erfindung ist bedeutsam durch ihre Formgebung, wie diese in der Zeichnung dargestellt ist,The cutting blade according to the invention is significant due to its shape, as shown in the drawing,

Aufgrund dieser Formgebung haben die Schneidzähne am Umfang der konkaven Schneidscheibe einen schrägen Angriffswinkel, derart, daß das Werkzeug gleich gut gegen Zweige, Sträucher, Gestrüpp, Gräser eingesetzt werden kann, solange sich diese noch in vertikaler Position befinden. Die abgeschnittenen, abgeschlagenen oder ausgerissenen, sodann am Erdboden liegenden Pflanzen werden dann mit dem gleichen Gerät in kleine Teile zerhackt, also zerstückelt.Because of this shape, the cutting teeth have on the circumference the concave cutting disc an oblique angle of attack, so that the tool is equally good against branches, shrubs, Scrub, grass can be used as long as they are still in a vertical position. The cut off, severed ones or plants that have been torn up and then lying on the ground are then broken into small pieces with the same device chopped up, that is, fragmented.

Die begrenzte Tiefe der Zähne, deren Zahl je nach Anwendungsfall wechselt, erlaubt ein progressives Eindringen der Klinge in Sträucher oder gar Bäume von relativ großem Querschnitt. Die dabei auftretenden Stöße sind bedeutend kleiner als bei viel teureren Maschinen vorbekannter Art. Aufgrund der Konkavität der Schneidscheibe hat man einen schrägen Angriffswinkel wie bei der Axt eines Holzfällers.The limited depth of the teeth, the number of which changes depending on the application, allows the blade to penetrate progressively in bushes or even trees with a relatively large cross-section. The resulting impacts are significantly smaller than with Much more expensive machines of the previously known type. Due to the concavity of the cutting disk, there is an oblique angle of attack like a lumberjack's ax.

Auf einem Rahmen oder Fahrgestell kann eine oder können mehrere Schneidwerkzeuge dieser Art angebracht sein. Die Klinge bzw. jede Klinge ist in Drehbewegung angetrieben. Die Antriebskraft ist von einem Motor abgeleitet. Das Schneidwerkzeug ist oben und seitlich von einem Schutzgehäuse abgedeckt. Das Schutz gehäuse und/oder das Schneidwerkzeug kann gegenüber einem das Gerät tragenden Fahrzeug angehoben und abgesenkt werden. Das Gerät kann auch selbstfahrend mit Rädern bzw. einem Fahrgestell ausgerüstet sein. Die Drehzahl der Schneidscheibe ist abhängig von der Art und Dichte und der Stärke der abzuschneidenden Pflanzen.One or more cutting tools of this type can be mounted on a frame or chassis. The blade or each blade is driven in rotary motion. The driving force is derived from an engine. The cutting tool is Covered at the top and at the sides by a protective housing. The protective housing and / or the cutting tool can be compared to that Device-carrying vehicle can be raised and lowered. The device can also be self-propelled with wheels or a chassis be equipped. The speed of rotation of the cutting disc depends on the type, density and thickness of the material to be cut Plants.

Zur näheren Erläuterung der Erfindung wird nachfolgend ein Ausführungsbeispiel anhand der Zeichnung beschrieben.To explain the invention in more detail, an exemplary embodiment is described below with reference to the drawing.

Fig. 1 zeigt eine Schneidscheibe gemäß der Erfindung von unten ! gesehen.Fig. 1 shows a cutting disc according to the invention from below ! seen.

Fig. 2 ist ein vertikaler Querschnitt durch Schneidscheibe und Gehäuse.Figure 2 is a vertical cross-section through the cutting disk and housing.

Die Schneidscheibe ist mit a, die Antriebsweile mit b und das Schutzgehäuse rait c bezeichnet.The cutting disc is marked with a, the drive shaft with b and the protective housing is called rait c.

Es versteht sich, daß die Erfindung nicht beschränkt ist auf dieses Ausführungsbeispiel. Die Konkavität sowie die Anzahl der Zähne werden angepaßt an die jeweiligen Verhältnisse. Zweckmäßig ist also ein ganzer Satz verschiedener Schneidscheiben vorgesehen.It goes without saying that the invention is not restricted to this exemplary embodiment. The concavity as well as the number the teeth are adapted to the respective conditions. A whole set of different cutting disks is therefore useful intended.
