Abstract

A receiving device for disintegrating machines, in particular for disintegrating vegetable remains and the like, is provided with a filling opening which is composed of four circular lateral openings which are situated opposite each other in pairs and at which a circular, common central opening is arranged. The lateral openings are constructed so as partly to overlap with the central opening. By this means, on the one hand, the statutory safety regulations, which have been called for, are satisfied and, on the other hand, the feeding of awkwardly shaped vegetable remains, such as branched branch material, is substantially facilitated in comparison with conventional openings. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Aufnahmevorrichtung für Zerkleinerungsmaschinen, insbesondere zum Zerkleinern von Gartenabfällen oder Pflanzenresten u.ä., mit mindestens einer Einfüllöffnung.The present invention relates to a holding device for shredding machines, in particular for shredding garden waste or plant residues and the like, with at least one filling opening.

Derartige Aufnahmevorrichtungen müssen den direkten Zugriff in die Maschine und das unbeabsichtigte Berühren der Schneidewerkzeuge in der Zerkleinerungsmaschine verhindern. Im Stand der Technik sind verschiedenartige Aufnahmevorrichtungen mit kreisförmigen (z.B. DE-A-32 26 677) oder länglichen (z.B. EP-A-0 253 232) Öffnungen mit parallelen Seitenwänden bekannt.Such pick-up devices must prevent direct access to the machine and unintentional touching of the cutting tools in the shredding machine. Various types of receptacles with circular (e.g. DE-A-32 26 677) or elongated (e.g. EP-A-0 253 232) openings with parallel side walls are known in the prior art.

Nachteilig an diesem Stand der Technik ist jedoch, daß zur Einhaltung der Sicherheitsvorschriften nach DIN 31001, Teil 1 und DIN 11004, Teil 1 Einfüllöffnungen mit parallelen Seitenwänden einen maximalen Abstand der Seiten von 30 mm bzw. die kreisförmigen Einfüllöffnungen einen maximalen Durchmesser von 50 mm aufweisen dürfen. Dadurch ist die Beschickmöglichkeit der bekannten Aufnahmevorrichtungen, insbesondere bei sperrigem Pflanzenmaterial, wie zum Beispiel verzweigtem Astmaterial, sehr eingeschränkt.A disadvantage of this prior art, however, is that in order to comply with the safety regulations according to DIN 31001, Part 1 and DIN 11004, Part 1, filling openings with parallel side walls have a maximum distance of 30 mm between the sides or the circular filling openings may have a maximum diameter of 50 mm. As a result, the possibility of loading the known receiving devices, in particular in the case of bulky plant material, such as branched branch material, is very limited.

Aufgabe der vorliegenden Erfindung ist es, eine Aufnahmevorrichtung für Zerkleinerungsmaschinen, insbesondere zum Zerkleinern von Pflanzenresten u.ä. bereitzustellen, die bei Einhaltung der geltenden Sicherheitsvorschriften eine verbesserte Beschickung der Zerkleinerungsmaschine mit Pflanzenresten u.ä. ermöglicht.The object of the present invention is to provide a receiving device for shredding machines, in particular for shredding plant residues and the like. To be provided, which in compliance with the applicable safety regulations, an improved loading of the shredder with plant residues and the like. enables.

Die Aufgabe wird dadurch gelöst, daß die Aufnahmevorrichtung eine Einfüllöffnung aus vier kreisförmigen, sich jeweils paarweise gegenüberliegenden seitlichen Öffnungen, die um eine kreisförmige, gemeinsame Zentralöffnung angeordnet sind, aufweist, wobei die seitlichen Öffnungen mit der Zentralöffnung teilweise überlappend ausgebildet sind.The object is achieved in that the receptacle has a filling opening made up of four circular side openings, each opposing each other in pairs, which are arranged around a circular, common central opening, the side openings being partially overlapping with the central opening.

In vorteilhafter Ausgestaltung weisen die kreisförmigen seitlichen Öffnungen und die kreisförmige Zentralöffnung einen Durchmesser von höchstens 50 mm auf.In an advantageous embodiment, the circular lateral openings and the circular central opening have a diameter of at most 50 mm.

In einer weiteren vorteilhaften Ausgestaltung weisen parallele Öffnungen, die im Überlappungsbereich der seitlichen Öffnungen mit der Zentralöffnung ausgebildet werden, eine Breite von höchstens 30 mm auf.In a further advantageous embodiment, parallel openings which are formed in the area of overlap of the lateral openings with the central opening have a width of at most 30 mm.

In einer besonders bevorzugten Ausführungsform ist die Einführungsöffnung kleeblattförmig ausgebildet.In a particularly preferred embodiment, the insertion opening is in the form of a cloverleaf.

Durch die Aneinanderreihung bzw. Überlappung der vier kreisförmigen seitlichen Öffnungen mit der gemeinsamen Zentralöffnung ergibt sich erfindungsgemäß eine verbesserte Einfüllöffnung, die zudem die gesetzlich geforderten Sicherheitsbestimmungen erfüllt. Dadurch ist es möglich, sperrige Pflanzenreste wie zum Beispiel verzweigtes Astmaterial ohne Schwierigkeiten und ohne vorhergehende Zerkleinerung dieses Materials der Zerkleinerungsvorrichtung über die Aufnahmeeinrichtung zuzuführen.The lining up or overlapping of the four circular side openings with the common central opening results in an improved filling opening according to the invention, which also fulfills the legally required safety regulations. This makes it possible to feed bulky plant residues, such as branched branch material, to the shredding device via the receiving device without difficulty and without prior shredding of this material.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung des in der Zeichnung dargestellten bevorzugten Ausführungsbeispieles.Further details, advantages and features of the invention also result from the following description of the preferred exemplary embodiment shown in the drawing.

Die Figur zeigt schematisch die Aufsicht auf die Einfüllöffnung 12 der Aufnahmevorrichtung für Zerkleinerungsvorrichtungen 10. Die Einfüllöffnung 12 umfaßt vier kreisförmige, einander jeweils paarweise gegenüberliegende seitliche Öffnungen 14a, 14b, 14c, 14d, die um eine kreisförmige, gemeinsame Zentralöffnung 16 angeordnet sind. Die seitlichen Öffnungen 14a bis 14d sind dabei mit der Zentralöffnung 16 teilweise überlappend ausgebildet. Der Durchmesser A der seitlichen Öffnungen 14a bis 14d sowie der Zentralöffnung 16 beträgt aufgrund der gesetzlichen Sicherheitsbestimmungen höchstens 50 mm. Des weiteren erkennt man, daß sich im Überlappungsbereich der seitlichen Öffnungen 14a bis 14d mit der Zentralöffnung 16 parallele Öffnungen 18a bis 18d ausbilden, die erfindungsgemäß eine Breite B von höchstens 30 mm aufweisen. Insgesamt zeigt die Figur die kleeblattförmige Ausbildung der Einfüllöffnung 12.The figure schematically shows the top view of the filling opening 12 of the holding device for comminution devices 10. The filling opening 12 comprises four circular side openings 14a, 14b, 14c, 14d, which are opposed to each other in pairs and which are arranged around a circular, common central opening 16. The lateral openings 14a to 14d are partially overlapping with the central opening 16. The diameter A of the lateral openings 14a to 14d and the central opening 16 is at most 50 mm due to the legal safety regulations. Furthermore, it can be seen that in the area of overlap of the lateral openings 14a to 14d, openings 18a to 18d are formed which are parallel to the central opening 16 and which according to the invention have a width B of at most 30 mm. Overall, the figure shows the cloverleaf-shaped design of the filling opening 12.
