Abstract

The compost shredder has a hopper (1) through which the material drops into a housing (2) contg. a blade assembly (3). The blade assembly consists of several blades mounted on a shaft with shorter points (5) alternating in axial direction with blades having longer points (6). In addition, the blades are radially staggered against each other. The blades with the longer points mesh with corresponding recesses (8) on the stationary counter blade assembly (4). During operating the material is cut on the longitudinal edges of the counter blade assembly and crushed on the sides of the recesses. The shaft (7) of the blade assembly is rotated by a crank handle.

Description

Handgerät zum Zerkleinern von Hand tool for shredding

Haus- und Gartenabfällen Die Erfindung betrifft ein Handgerät zum Zerkleinern von Haus- und Gartenabfällen mit einem drehbaren Messer und einem Gegenmesser. House and garden waste The invention relates to a hand-held device for Shredding household and garden waste with a rotating knife and a counter knife.

Ein bekanntes Gerät dieser Art weist als Messer eine elliptische Schnittscheibe auf. Dieses Gerät ist zur Herstellung kompostierbaren Abfalls nicht geeignet, da der Abfall bei einer bestimmten Messerstellung unzerkleinert durch die Vorrichtung fallen kann und darüberhinaus härterer Abfall nur mit großem Kraftaufwand zerkleinert werden kann.A known device of this type has an elliptical cutting disk as a knife on. This device is not suitable for the production of compostable waste because the waste at a certain knife position is not comminuted by the device can fall and, moreover, harder waste can only be crushed with great effort can be.

Der Erfindung liegt die Aufgabe zugrunde, ein Handgerät der eingangs genannten Gattung vorzuschlagen, mit dem Abfälle gleichmäßig und mit geringem Kraftaufwand zerkleinert werden können.The invention is based on the object of providing a hand-held device of the initially described to propose the type mentioned, with the waste evenly and with little effort can be crushed.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Messer aus einer Messerwalze mit versetzt angeordneten Messerspitzen mit unterschiedlichen Abständen von der Achse besteht und das Gegenmesser Ausnehmungen im Bereich der langen Messerspitzen aufweist.According to the invention this object is achieved in that the knife from a knife roller with staggered knife tips with different There are clearances from the axis and the counter knife has recesses in the area of the has long knife tips.

Der mit dem erfindungsgemäßen Handgerät erzielbare Vorteil besteht darin, daß alle kompostierbaren Garten-und Hausabfälle ohne großen Kraftaufwand gleichmäßig zerkleinert werden können. Da an den Längskanten des Gegenmessers geschnitten wird, an den Seiten der Ausnehmungen das Material dagegen gequetscht wird, wird das Material sowohl geschnitten als auch gefasert, so daß die die Kompostierung bewirkenden Mikroorganismen eine größere Angriffsfläche vorfinden, wodurch der Kompostierungsvorgang beschleunigt wird.The advantage that can be achieved with the hand-held device according to the invention is there in that all compostable garden and house waste without much effort can be crushed evenly. Because cut on the long edges of the counter knife on the other hand, the material is squeezed on the sides of the recesses the material is both cut and fiberized so that the composting causing microorganisms find a larger attack surface, whereby the composting process is accelerated.

In einer vorteilhaften Ausgestaltung der Erfindung ist die Messerwalze durch eine herkömmliche elektrische Handbohrmaschine antreibbar. Dazu weist sie eine Vorrichtung zum Anschluß der elektrischen Handbohrmaschine auf. Vorteilhaft ist die Vorrichtung abnehmbar am Gehäuse befestigt. Der Vorteil besteht darin, daß das Handgerät auch elektrisch betrieben werden kann, ohne daß ein gesonderter elektrischer Motor beschafft werden muß.In an advantageous embodiment of the invention, the knife roller can be driven by a conventional electric hand drill. She points to this a device for connecting the electric hand drill. Advantageous the device is detachably attached to the housing. The advantage is that the hand-held device can also be operated electrically without a separate electrical Engine must be procured.

In einer weiteren Ausgestaltung weist das Gerät ein Getriebe und eine Halterung zum Fixieren der elektrischen Bohrmaschine auf, wobei die Halterung und das antreibende Teil des Getriebes abnehmbar sein können.In a further embodiment, the device has a transmission and a Bracket for fixing the electric drill on, the bracket and the driving part of the transmission can be removable.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. In der Zeichnung zeigen: Fig. 1 einen Querschnitt durch das Handgerät; Fig. 2 eine Draufsicht auf das Handgerät und Fig. 3 eine Draufsicht auf das Handgerät mit angeschlossener elektrischer Handbohrmaschine.The invention is explained in more detail below with reference to the drawing. The drawings show: FIG. 1 a cross section through the hand-held device; Fig. 2 a Top view of the hand-held device and FIG. 3 is a top view of the hand-held device with a connected device electric hand drill.

Das dargestellte, per Hand antreibbare Zerkleinerungsgerät weist einen Einfülltrichter 1 auf, über den das zu zerkleinernde Material einer in einem Gehäuse 2 angeordneten Messeranordnung zugeführt wird. Die Messeranordnung besteht aus einer Messerwalze 3 und einem am Gehäuse 2 befestigten Gegenmesser.The shredding device shown, which can be driven by hand, has a Filling funnel 1, through which the material to be crushed is placed in a housing 2 arranged knife assembly is supplied. The knife assembly consists of one Knife roller 3 and a counter knife attached to the housing 2.

Die Messerwalze weist versetzt angeordnete Messerspitzen 5,6 mit unterschiedlichen Abständen von der Achse 7 auf.The knife roller has knife tips 5, 6 arranged offset with different ones Distances from the axis 7.

Das Gegenmesser 4 weist im Bereich der langen Messerspitzen 6 Ausnehmungen 8 auf. Das zu zerkleinernde Material wird an den Längskanten der Gegenmesser geschnitten u-nd an den Seiten in den Ausnehmungen 8 gequetscht.The counter knife 4 has 6 recesses in the area of the long knife tips 8 on. The material to be shredded is cut on the longitudinal edges of the counter knife and squeezed in the recesses 8 on the sides.

Die Achse der Messerwalze 8 ist mit einer Handkurbel 9 bzw.The axis of the knife roller 8 is with a hand crank 9 resp.

einer mit Handgriffen versehenen Schwungscheibe verbunden.connected to a flywheel provided with handles.

Bei der in Fig.3 dargestellten Ausführungsform ist an dem Handgerät eine herkömmliche elektrische Bohrmaschine 10 angeschlossen. Die Messerwalze 3 wird über ein Getriebe mit geeigneter Untersetzung, bestehend aus den Zahnrädern 11 und 12, angetrieben. Das Zahnrad 11 bildet mit einer Halterung 13 für die Bohrmaschine eine Baueinheit, die abnehmbar am Gehäuse 2 befestigt ist. Aus Sicherheitsgründen muß die Handkurbel 9 abgenommen werden, sobald der Antrieb mittels der elektrischen Handbohrmaschine erfolgt.In the embodiment shown in Figure 3 is on the handheld device a conventional electric drill 10 is connected. The knife roller 3 is Via a gear with a suitable reduction, consisting of the gears 11 and 12, driven. The gear 11 forms with a holder 13 for the drill a structural unit which is detachably attached to the housing 2. For safety reasons the hand crank 9 must be removed as soon as the drive by means of the electric Hand drill takes place.
