Abstract
Description
Beschreibungdescription
Die Erfindung bezieht sich auf eine Anordnung der im Oberbegriff des Anspruchs 1 bezeichneten Art.The invention relates to an arrangement of the in the preamble of Claim 1 designated Art.
Bei einem solchen nach dem DT-GM 1 751 021 bekannten Mehrzweckgerät besteht für die Bedienungsperson der Vorteil, daß ohne Vorbereitungsmaßnahmen stets ein betriebsbereiter Rasenmäher verfügbar ist, während bei anderen bekannten Mehrzweckeinrichtungen der Motorteil auch zum Rasenmähen mit der Schneideinrichtung verbunden werden muß.In such a multi-purpose device known from DT-GM 1 751 021 there is the advantage for the operator that without any preparatory measures an operational lawn mower is available while at other known multipurpose facilities the motor part must also be connected to the cutting device for mowing the lawn.
Würde man eine Flüssigkeitspumpe und insbesondere eine selbstan saugende Gartenpumpe mit einem Rasenmäher der eingangs genannten Art betreiben, so würde ein hoher Anteil der verfügbaren Motorleistung durch die mitlaufende Schneideinrichtung verbraucht, so daß der Antrieb einer Flüssigkeitspumpe nur bei geringer Förderleistung möglich wäre. Eine Gartenberegung wäre dann nicht möglich. Darüber hinaus würde das Geräusch der Schneideinrichtung bei längerfristig betriebenen Flüssigkeitspumpen stören. Bei Unachtsamkeit besteht Verletzungsgefahr.One would use a liquid pump and especially a self-sucking one Operate garden pump with a lawnmower of the type mentioned, so would a high proportion of the available engine power thanks to the cutting device that moves along with it consumed, so that the drive of a liquid pump only at a low delivery rate it is possible. A garden irrigation would then not be possible. In addition, would the noise of the cutting device with long-term operated liquid pumps disturb. In the event of carelessness there is a risk of injury.
Der Erfindung liegt die Aufgabe zugrunde, das Mehrzweckgerät der eingangs beschriebenen Art so zu gestalten, daß ohne Erhöhung der Motorleistung auch Zusatzgeräte mit höherem Leistungsbedarf wie z. B. Gartenpumpen bei möglichst geringer Geräuschentwicklung angetrieben werden können.The invention is based on the object of the multi-purpose device of the introduction described type so that without increasing the engine power and additional devices with higher power requirements such as B. garden pumps with the lowest possible noise can be driven.
Die Lösung gelingt durch die im Anspruch 1 gekennzeichneten Merkmale. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.The solution is achieved by the features characterized in claim 1. Advantageous embodiments of the invention are characterized in the subclaims.
Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels erläutert. Die Fig. zeigt den Prinzipaufbau eines erfindungsgemäß aufgebauten Mehrzweckgerätes mit angekuppelter Gartenpumpe.The invention is based on an embodiment shown in the drawing explained. The figure shows the basic structure of a multi-purpose device constructed according to the invention with a coupled garden pump.
Auf dem Fahrgestell 1 ist unterhalb der Abdeckhaube 2 der Elektromotor 3 befestigt. Das senkrecht nach unten ragende Wellenende 4 treibt die als Messerbalken ausgebildete Schneideinrichtung 5 über die Freilaufkupplung 6 an. Lösbar mit dem Gehäuse des Motors 3 sind Arme 7,7' der Flüssigkeitspumpe 8 derart verbunden, daß sich eine möglichst gute Fluchtung des über die Kupplung 9 verbundenen Wellenendes 10 des Motors und der im Pumpengehäuse gelagerten Pumpenwelle 11 ergibt.On the chassis 1, below the cover 2, the electric motor is located 3 attached. The vertically downwardly protruding shaft end 4 drives as a cutter bar trained cutting device 5 via the overrunning clutch 6. Solvable with the Housing of the motor 3 arms 7,7 'of the liquid pump 8 are connected in such a way that the best possible alignment of the shaft end connected via the coupling 9 10 of the motor and the pump shaft 11 mounted in the pump housing results.
Sollte aus der Wellendichtung der Pumpe Leckwasser austreten, so wird dieses durch die an der Kupplung vorgesehene Schleuderscheibe 12 an der Fortleitung zum Motor gehindert. Der Durchmesser der Schleuderscheibe 12 ist größer als der Durchmesser der Durchgangsbohrung 13 in der Abdeckhaube 2.If leakage water should escape from the shaft seal of the pump, then this through the flinger 12 provided on the coupling to the forwarding hindered to the engine. The diameter of the slinger 12 is larger than that Diameter of the through hole 13 in the cover 2.
Die Drehrichtungsumkehr des Motors 3 kann durch einen am Bedienungsgriff des Rasenmähers angeordneten und von Hand betitigbaren Reversierschalter bewirkt werden. Vorteilhafter ist jedoch, den Reversierschalter am Motor derart anzuordnen, daß er durch das aufgesetzte Zusatzgerät betätigt wird.The direction of rotation of the motor 3 can be reversed by means of an operating handle the lawnmower arranged and manually operable reversing switch causes will. However, it is more advantageous to arrange the reversing switch on the motor in such a way that that it is operated by the attached additional device.
Bei umgekehrter Drehrichtung ist die kraftschlüssige Verbindung zwischen Motor 3 und Schneideinrichtung 5 gelöst. Damit auch geringe Rest-Reibungsmomente nicht ein schwaches Mitdrehen der Schneideinrichtung bewirken, kann eine Bremseinrichtung 14 vorgesehen sein.If the direction of rotation is reversed, the non-positive connection is between Motor 3 and cutting device 5 released. This means that there are also low residual frictional torques A braking device cannot cause the cutting device to rotate too weakly 14 may be provided.
Bei einem erfindungsgemäß gestalteten Mehrzweckgerät kann der Lüfter zur Kühlung des Motors vorteilhaft am die Schneideinrichtung antreibenden Wellenende 4 des Motors 3 angeordnet sein, so daß an der anderen Motorseite unbehindert Platz für die Einrichtungen zur Ankupplung der Zusatzgeräte verbleibt.In a multi-purpose device designed according to the invention, the fan can for cooling the motor, advantageously at the end of the shaft driving the cutting device 4 of the motor 3 can be arranged so that there is unimpeded space on the other motor side remains for the facilities for coupling the additional devices.
Falls der Lüfter jedoch am für die Zusatzgeräte vorgesehenen Wellenende angeordnet ist, kann er gleichzeitig als Kupplung ausgebildet sein.However, if the fan is on the shaft end intended for the additional devices is arranged, it can be designed as a coupling at the same time.
