Description

Die Erfindung betrifft einen Gartenhäcksler nach dem Oberbegriff des Anspruchs 1.The invention relates to a garden shredder according to the preamble of claim 1.

Entsprechende Gartenhäcksler (im Folgenden vereinfacht auch Häcksler) sind seit langem bekannt. Alle Häcksler weisen einen Zuführkanal auf, der über eine Einführöffnung mit Gartenabfällen beladen wird. Über eine Häckselvorrichtung werden die Abfälle zerkleinert, und über einen Auswurfkanal mit einer Auswurföffnung ausgeworfen. Ein derartiger Gartenhäcksler ist aus DE 311 8518 bekannt.Corresponding garden shredders (simplified in the following also shredders) have long been known. All shredders have a feed channel, which is loaded via an insertion with garden waste. About a chopper, the waste is crushed, and ejected through an ejection channel with a discharge opening. Such a garden shredder is out DE 311 8518 known.

Hinsichtlich der Gestaltung der Auswurföffnung besteht ein Zielkonflikt. Zum Einen muss diese hinreichend groß sein, damit sie durch nachgeschobenes Material nicht verstopft. Zum anderen darf sie nicht so groß sein, dass eine Person mit der Hand in den Bereich der Häckselvorrichtung gelangen kann.With regard to the design of the ejection opening, there is a conflict of objectives. On the one hand, this must be sufficiently large so that it does not become clogged by the material being fed. On the other hand, it must not be so large that a person can get into the area of the chaffing device by hand.

Dazu wurde in der Vergangenheit vorgeschlagen, den Auswurfkanal entsprechend zu verlängern, jedoch wird dadurch die Gefahr von Verstopfungen nicht verhindert. Ist der Auswurfkanal einmal verstopft, kann er von Hand nur schwer frei geräumt werden, weil bei zu langen Kanälen die Hand nicht in den gesamten Bereich bis zum Schneidwerk vordringen kann.For this purpose, it has been proposed in the past to extend the discharge channel accordingly, but this does not prevent the risk of blockages. Once the chute is blocked, it can hardly be cleared by hand, because if the channels are too long, the hand can not reach all the way to the cutting unit.

Zum Anderen wurde vorgeschlagen, die Auswurföffnung bei gleichzeitiger Verkürzung des Auswurfkanals zu vergittern. Allerdings stellt das Gitter dann ein Hindernis dar, welches wiederum die Verstopfung begünstigt. Aufgabe der vorliegenden Erfindung ist es daher, einen Gartenhäcksler der eingangs genannten Art anzugeben, der einen möglichst kurzen Auswurfkanal aufweist und trotzdem die Gefahr von Verstopfungen weiter reduziert.On the other hand, it has been proposed to grill the ejection opening while simultaneously shortening the ejection channel. However, the grid is then an obstacle, which in turn favors the blockage. Object of the present invention is therefore to provide a garden shredder of the type mentioned, which has the shortest possible discharge channel and still further reduces the risk of blockages.

Gelöst wird diese Aufgabe durch einen Gartenhäcksler mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausführungsformen finden sich in den Unteransprüchen.This object is achieved by a garden shredder with the features of claim 1. Advantageous embodiments can be found in the subclaims.

Erfindungsgemäß ist vorgesehen, dass der Gartenhäcksler am Ende des Auswurfkanals einen speziell ausgestalteten Auswurfabschnitt aufweist. Es sind dazu im Bereich des Auswurfabschnitts voneinander beabstandete Vorsprünge vorgesehen. Diese Vorsprünge erstrecken sich von einer oder der Wand des Auswurfabschnitts über einen Teil der Breite der Auswurföffnung. Die Vorsprünge ragen folglich in die Auswurföffnung hinein, und zwar überspannen sie die Öffnung nicht vollständig, so dass eine Mehrzahl Finger einer Hand mit den Vorsprüngen dazwischen in den Auswurfkanal hineinreichen können, ohne Gefahr zu laufen, mit dieser Messerscheibe in Kontakt zu kommen.According to the invention, the garden shredder has a specially designed ejection section at the end of the ejection channel. There are provided for this purpose in the region of the ejection section spaced apart projections. These projections extend from one or the wall of the ejection section over part of the width of the ejection opening. The protrusions thus protrude into the ejection opening, and do not completely span the opening, so that a plurality of fingers of a hand with the protrusions therebetween can extend into the ejection channel without running the risk of coming into contact with this knife disk.

Dabei ist bevorzugt vorgesehen, dass die Vorsprünge so ausgelegt sind, dass zwischen zwei benachbarte Vorsprünge ein VDE-Prüffinger aufgenommen werden kann. So kann insbesondere sicher gestellt werden, dass der kürzeste Abstand, gemessen im Kettenmaß, zwischen der Häckselvorrichtung, insbesondere dem äußeren Rand von deren Messerscheibe, und dem Rand der Auswurföffnung größer als 80 mm beträgt. Aufgrund der endlichen Dicke des VDE-Prüffingers kann das Kettenmaß sogar geringfügig unter 80 mm liegen. So kann gewährleistet werden, dass auch bei Hineinreichen in den Auswurfkanal kein Finger in Kontakt mit dem Schneidwerk kommt. Die Länge des Auswurfkanals kann so minimiert werden.It is preferably provided that the projections are designed so that between two adjacent projections a VDE test finger can be added. Thus, it can be ensured in particular that the shortest distance, measured in the chain dimension, between the chopping device, in particular the outer edge of the cutter disk, and the edge of the ejection opening is greater than 80 mm. Due to the finite thickness of the VDE test finger, the chain dimension can even be slightly below 80 mm. This can be guaranteed that no finger comes into contact with the cutting mechanism even when reaching into the discharge chute. The length of the discharge channel can be minimized.

Der Auswurfabschnitt kann an wenigstens einer Wand gegenüber dem übrigen Auswurfkanal abgewinkelt sein, so dass der Abwurf nach unten erfolgt und dadurch Personen in der Umgebung nicht gefährdet werden.The ejection section may be angled against at least one wall opposite to the rest of the ejection channel, so that the ejection is done downwards and thereby persons in the environment are not endangered.

Die Vorsprünge können zur Verbesserung des Materialflusses in Auswurfrichtung verschiedene geometrische Besonderheiten auf-weisen, die kumuliert oder einzeln vorgesehen sein können. So ist vorgesehen, dass die Vorsprünge sich in Auswurfrichtung verjüngen. So bilden sie eine Führung des auszuwerfenden Materials und der Widerstand nimmt in Richtung der Auswurföffnung ab. Insbesondere kann auch vorgesehen sein, dass die Vorsprünge auf ihren dem ankommenden gehäckselten Material zugewandten Seiten abgerundete Kanten aufweisen. Weiter können zwischen benachbarten Vorsprüngen Rücksprünge mit gewölbter Oberfläche vorgesehen sein. Die Wölbung ist bevorzugt konkav, so dass zum Einen die Zwischenräume und damit auch die zur Verfügung stehende Auswurföffnung maximiert werden. Ferner reduzieren Rundungen die Reibung zwischen dem Material und dem Auswurfkanal gegenüber scharfen Kanten deutlich.The projections may have different geometric features to improve the flow of material in the direction of ejection, which may be cumulative or provided individually. Thus, it is provided that the projections taper in the ejection direction. So they form a guide of the material to be ejected and the resistance decreases in the direction of the ejection opening. In particular, it can also be provided that the projections have rounded edges on their sides facing the incoming chopped material. Further, recesses with a curved surface may be provided between adjacent protrusions. The curvature is preferably concave, so that on the one hand, the gaps and thus the available ejection opening are maximized. Further, rounding significantly reduces the friction between the material and the discharge chute over sharp edges.

Schließlich können die Vorsprünge im Wesentlichen in Auswurfrichtung verlaufende Schrägflächen aufweisen. Diese Schrägflächen, die sich zur Auswurföffnung hin noch verjüngen können, sorgen für eine Führung des ankommenden Materials, so dass auf diese Weise der durch die Vorsprünge auf das ankommende Häckselmaterial ausgeübte Widerstand reduziert werden kann.Finally, the projections may have substantially oblique surfaces extending in the direction of ejection. These inclined surfaces, which can still taper towards the ejection opening, provide a guide of the incoming material, so that in this way by the protrusions on the incoming chopped material can be reduced resistance.

Die Erfindung wird nachfolgend anhand des in den Figuren 1 bis 3 gezeigten Ausführungsbeispiels näher erläutert.

  • Figur 1 zeigt eine perspektivische Schnittansicht durch den erfindungsgemäßen Gartenhäcksler von einer ersten Seite.
  • Figur 2 zeigt eine seitliche Schnittansicht durch den erfindungsgemäßen Gartenhäcksler.
  • Figur 3 zeigt eine perspektivische Schnittansicht durch den erfindungsgemäßen Gartenhäcksler von einer zweiten Seite.
The invention will be described below with reference to the FIGS. 1 to 3 shown embodiment explained in more detail.
  • FIG. 1 shows a perspective sectional view through the garden shredder according to the invention from a first side.
  • FIG. 2 shows a side sectional view through the garden shredder according to the invention.
  • FIG. 3 shows a perspective sectional view through the garden shredder according to the invention from a second side.

Der in den Figuren 1 bis 3 gezeigte Gartenhäcksler weist ein Gehäuse 3 auf, welches durch die hier gezeigte vordere Wand 3a, die Rückwand 3c und die Oberseite 3b begrenzt wird. In der Oberseite 3b ist eine Einwurföffnung 1 vorgesehen, an die sich der als Zuführschacht dienende Einwurfkanal 2 anschließt, durch welchen zu häckselndes Material eingeführt werden kann. Dieser Zuführschacht 2 führt zur Häckselvorrichtung, welche einen Motor 4 umfasst, welcher wiederum eine Messerscheibe 5 antreibt. Die Messerscheibe 5 weist Messer 7 auf, welche mit einem festen Gegenmesser 6 im Bereich einer Scherstelle 8 zusammenwirken. Das durch den Zuführschacht 2 zugeführte Material wird so zerkleinert und gelangt dann in den Raum 9 auf der dem Zuführschacht 2 abgewandten Seite der Messerscheibe 5 und von dort aus in den in der Zeichnung schräg nach unten, in Auswurfrichtung X verlaufenden Auswurfkanal 10. Der Auswurfkanal 10 ist bevorzugt so orientiert, dass dessen Verlaufsrichtung wenigstens eine Komponente in Richtung des Bodens (nicht gezeigt) aufweist, auf welchem der Häcksler steht. Damit wird gewährleistet, dass das der Auswurf des auszuwerfenden Materials durch die Schwerkraft unterstützt wird.The in the FIGS. 1 to 3 shown garden shredder has a housing 3, which is bounded by the front wall 3a shown here, the rear wall 3c and the top 3b. In the upper side 3b, an insertion opening 1 is provided, which is adjoined by the feed channel 2 serving as a feed chute, through which material to be chopped can be introduced. This feed chute 2 leads to the chopping device, which comprises a motor 4, which in turn drives a cutter disk 5. The knife disk 5 has knives 7, which cooperate with a fixed counter knife 6 in the region of a shearing point 8. The fed through the feed chute 2 material is crushed and then enters the room 9 on the side facing away from the feed chute 2 of the cutter disk 5 and from there into the obliquely downward in the drawing, in the direction of ejection X extending ejection channel 10. The discharge channel 10 is preferably oriented so that the direction of at least one component in the direction of the bottom (not shown), on which the shredder is. This ensures that the ejection of the material to be ejected is supported by gravity.

Der Auswurfkanal 10 mündet in einer Auswurföffnung 12, die Teil eines am Ende des Auswurfkanals 10 vorgesehenen Auswurfabschnitts 11 ist. Dieser Abschnitt 11 ist im gezeigten Beispiel gegenüber dem übrigen Auswurfkanal 10, welcher sich im Wesentlichen in Auswurfrichtung X (vgl. Figur 2) erstreckt, abgewinkelt, so dass die Auswurföffnung 12 parallel zur Einführöffnung 1 liegt bzw. im Wesentlichen in Richtung auf den Boden weist. In die Auswurföffnung 12, bzw. in das Innere des Auswurfabschnitts 11 ragen Vorsprünge 13a, 13b, 13c (in Ihrer Gesamtheit auch mit 13 bezeichnet) hinein, die damit einen Teil der Auswurföffnung 12 verschließen, so dass nur noch einzelne Finger in die Rücksprünge zwischen benachbarten Vorsprüngen 13a, 1b, 13c, nicht aber die Handfläche einer Hand in den Auswurfkanal 10 hinein langen können. Der im Kettenmaß gemessene kürzeste Abstand zwischen dem äußeren Rand der Messerscheibe 5 und der Auswurföffnung 12 kann so minimiert werden auf die durch den VDE-Prüffinger vorgesehene Mindestlänge von 80 mm oder aufgrund der endlichen Dicke des VDE-Prüffingers geringfügig darunter. Die Zwischenräume zwischen den Vorsprüngen sind so gewählt, dass der VDE-Prüffinger durch diese Zwischenräume geführt werden kann.The discharge channel 10 opens into an ejection opening 12 which is part of an ejection section 11 provided at the end of the ejection channel 10. In the example shown, this section 11 is opposite the remaining discharge channel 10, which essentially extends in the ejection direction X (cf. FIG. 2 ), angled, so that the ejection opening 12 is parallel to the insertion opening 1 or points substantially in the direction of the ground. In the ejection opening 12, or in the interior of the ejection section 11 protrude projections 13a, 13b, 13c (also referred to in their entirety with 13) into it, thus closing a part of the ejection opening 12, so that only a few fingers in the recesses between adjacent projections 13a, 1b, 13c, but not the palm of a hand in the discharge channel 10 can go into it. The measured in the chain dimension shortest distance between the outer edge of the cutter disk 5 and the ejection opening 12 can be minimized so to the provided by the VDE test finger minimum length of 80 mm or due to the finite thickness of the VDE test finger slightly below. The spaces between the projections are chosen so that the VDE test finger can be passed through these spaces.

Die Vorsprünge 13 schließen sich an einen durchgehenden Abschnitt 10a des Auswurfkanals 10 an und weisen auf deren Oberseiten wenigstens abschnittweise dasselbe Gefälle auf wie der Abschnitt 10a des Auswurfkanals 10. Weiter sind die so im Wesentlichen in Auswurfrichtung X verlaufenden Schrägflächen der Vorsprünge an ihren Seiten abgerundet, so dass ein Steckenbleiben von Material an scharfen Kanten vermieden wird. Weiter sind die Vorsprünge 13 in Richtung X bzw. zur Öffnung 12 hin verjüngend ausgebildet. Zudem können zur Reduzierung des Reibungswiderstandes zwischen dem auszuwerfenden Material die Übergänge zwischen den aus der Wand 11a des Auswurfabschnitts 11 ins Innere vorstehenden Vorsprüngen 13 und der Wand 11a sowie zu den Rücksprüngen in den Zwischenräumen abgerundet sein. Insbesondere können die Rücksprünge in den Zwischenräumen zwischen benachbarten Vorsprüngen gewölbt, insbesondere konkav gewölbt sein.The projections 13 adjoin a continuous section 10a of the ejection channel 10 and have on their tops at least in sections the same gradient as the section 10a of the ejection channel 10. Further, the oblique surfaces of the projections thus extending substantially in the direction of ejection X are rounded at their sides, so that a sticking of material to sharp edges is avoided. Further, the projections 13 are tapered in the direction X and the opening 12. In addition, in order to reduce the frictional resistance between the material to be ejected, the transitions between the protrusions 13 protruding from the wall 11a of the ejection portion 11 and the wall 11a and the recesses in the spaces may be rounded. In particular, the recesses in the spaces between adjacent projections can be arched, in particular concavely arched.
