Abstract

By means of the unit, private and public areas can be mechanically rid of leaves. At the same time, these leaves are disintegrated, so that the bulk density is substantially increased, the disintegrated material is excellently suited for composting and, as experience has shown, the leaves, if they are not transported away, decompose more rapidly as a result of the disintegration process. The leaves are carried by means of an air current through a cutting channel. In the cutting channel, rotating knives are seated on a shaft and disintegrate the leaves. By means of a blower part, the material reaches the outlet opening, at which it can be introduced into containers or blown into the open. The shapes and the arrangement of the knives have proven particularly advantageous.

Description

Die Erfindung bezieht sich auf ein Zerkleinerungsaggre­ gat gemäß dem Oberbegriff des Anspruchs 1. Vorzugsweise ist die Neuerung mit einem Saugkanal (1) und einem Ge­ bläse (5) konstruktiv vereinigt.The invention relates to a Zerkleinerungsaggre gat according to the preamble of claim 1. Preferably, the innovation with a suction channel ( 1 ) and a Ge blower ( 5 ) is structurally combined.

Der Erfindung liegt die Aufgabe zugrunde alle Laubsorten auf beliebigem Untergrund aufzunehmen und zu zerkleinern, um dadurch den allgemeinen Stand der Technik zu verbessern.The invention is based on the object of all types of leaves pick up and shred on any surface, to thereby improve the general state of the art.

Von besonderer Bedeutung für den Erfindungsgegenstand ist seine vielseitige Kombinierbarkeit mit bestehenden Geräten zur rationellen Straßen, Grundstücks, Anlagen- und Sport­ platzpflege. Beispielsweise können Mehrzweckarbeitsma­ schinen mit hydrostatischem Antrieb, Benzin- oder Dieselmo­ tor sowie einer Dreipunktaufhängung zur Geräteaushebung mit dem Aggregat ausgestattet werden. Für Kompaktschlepper trifft dies ebenso zu. Außerdem ist die Erfindung für manu­ ellen Betrieb in Kombination mit einem Elektro, Diesel- oder Benzinmotor als Antrieb für das Gebläse und das Messerwerk einsetzbar. Anhänger für Aufsitzmäher können mit der Erfin­ dung auch ausgestattet werden. Grundsätzlich ist die Einsetz­ barkeit des Erfindungsgegenstandes auf die bisher angeführten Verwendungsmöglichkeiten nicht beschränkt.Is of particular importance for the subject matter of the invention its versatile combinability with existing devices for rational roads, land, facilities and sports place maintenance. For example, multipurpose labor machines with hydrostatic drive, petrol or diesel engines gate and a three-point hitch for device lifting can be equipped with the unit. For compact tractors this also applies. In addition, the invention is for manu Operation in combination with an electric, diesel or Petrol engine as drive for the blower and the knife mechanism applicable. Trailers for ride-on mowers can with the inven can also be equipped. Basically, the stake Availability of the subject of the invention to the previously mentioned Possible uses are not restricted.

Die erfindungsgemäßen Merkmale sind aus den Ansprüchen 1-3 entnehmbar.The features of the invention are from claims 1-3 removable.

Die folgende Beschreibung erfolgt anhand der Fig. 1a und 1b und dient der näheren Erläuterung der Erfindung. The following description is based on FIGS. 1a and 1b and serves to explain the invention in more detail.

Das auf dem Boden befindliche Laub (9) wird über einen Luft­ strom, der in der Fig. 1a durch Pfeile gekennzeichnet ist über einen Saugkanal (1) dem Schnittkanal (2) zugeführt. Im Schnittkanal befindet sich eine beidseitig gelagerte Sechs­ kantwelle (3) mit Distanzscheiben (7). Auf der Sechskantwelle sitzen ca. 20 Stück Schnittmesser (4) um jeweils 45 Grad ver­ setzt. Die Geometrie der Schnittmesser, die Lage der Schneid­ kanten und die Anordnung der Messer ist in Fig. 1b prinzi­ piell dargestellt. Durch Rotation der Welle, hervorgerufen durch ein Antriebselement (Elektro, Benzin- Diesel- oder Hydro­ motor) wird das sich im Luftstrom befindliche Laub von den rotierenden, sichelförmigen Messern (Fig. 1b) zerkleinert. Das zerkleinerte Laub wird mittels eines Gebläses (5), das sich zwischen Antriebselement (8) und Messerwerk (4) befindet, zur Auslaßöffnung (6) im Luftstrom transportiert und ausge­ blasen. Hier kann es beispielsweise in Säcke abgefüllt werden. Eine Anschlußmöglichkeit für Behältnisse bietet ein Flansch (7), direkt an der Auslaßöffnung.The leaves ( 9 ) on the ground are fed via an air flow, which is indicated in FIG. 1a by arrows, via a suction channel ( 1 ) to the cutting channel ( 2 ). A hexagonal shaft ( 3 ) with spacers ( 7 ) is located on both sides in the cutting channel. Approx. 20 cutting knives ( 4 ) are seated on the hexagon shaft at 45 degrees. The geometry of the cutting knife, the position of the cutting edges and the arrangement of the knife is shown in principle in Fig. 1b. By rotating the shaft, caused by a drive element (electric, gasoline, diesel or hydraulic motor), the leaves in the air stream are crushed by the rotating, sickle-shaped knives ( Fig. 1b). The shredded leaves are transported by means of a blower ( 5 ), which is located between the drive element ( 8 ) and knife mechanism ( 4 ), to the outlet opening ( 6 ) in the air stream and blow out. Here it can be filled into sacks, for example. A connection option for containers is provided by a flange ( 7 ), directly at the outlet opening.

Claims (3)

1. Laubzerkleinerungsaggregat zum Aufsaugen und im wesentlichen zum Zerkleinern von allen Laubsorten; einsetzbar auf beliebi­ gem Untergrund.
Das System ist dadurch gekennzeichnet, daß mittels eines Luft­ stromes durch einen Saugkanal (1) Laub angesaugt wird. Der Luftstrom führt dem Schnittkanal (2) das Laub zu. Im Schnitt­ kanal sitzen auf einer Sechskantwelle (3) ca. 20 Stück Schnitt­ messer (4) um jeweils 45 Grad versetzt. Der Messerabstand wird durch Distanzscheiben (7) erzeugt. Durch die besondere Geometrie der Schnittmesser (4) und der Drehbewegung der Welle (3) im Luftstrom wird das Laub zerkleinert. Über ein Gebläse (5) kommt das zerkleinerte Gut zur Auslaßöffnung (6).1. Leaf shredding unit for sucking up and essentially for shredding all types of leaves; can be used on any surface.
The system is characterized in that leaves are sucked in by means of an air flow through a suction channel ( 1 ). The air flow feeds the leaves to the cut channel ( 2 ). Approx. 20 cutting knives ( 4 ) sit on the hexagonal shaft ( 3 ) in the cutting channel, each offset by 45 degrees. The knife distance is generated by spacers ( 7 ). Due to the special geometry of the cutting blades ( 4 ) and the rotary movement of the shaft ( 3 ) in the air flow, the leaves are shredded. The comminuted material comes to the outlet opening ( 6 ) via a blower ( 5 ). 2. Zerkleinerungsaggregat nach Anspruch 1, dadurch gekennzeich­ net, daß die Anordnung und die Geometrie der Messer im skizzier­ ten System einen hohen Zerkleinerungsgrad hervorrufen.2. Comminution unit according to claim 1, characterized net that the arrangement and geometry of the knife in the sketch cause a high degree of comminution. 3. Zerkleinerungsaggregat nach Anspruch 1 + 2, dadurch gekennzeich­ net, daß zur entscheidenden Baugruppe Schnittkanal (2) mit Schnittmesser (4) die Baugruppen Saugkanal und Gebläse funkti­ onsgerecht angepaßt sind.3. Shredding unit according to claim 1 + 2, characterized in that the decisive assembly section channel ( 2 ) with cutting knife ( 4 ), the modules suction channel and blower are adapted to suit the functions.
