Abstract

A wood chipping assembly has a frame with two parallel contra-rotating helical cutting-profile shafts. The shafts are at least partly enclosed by a chip grading basket. The cutting interface gap between the two shafts is fed from above by an elongated funnel. Chips falling from the cutting interface fall through the basket into a trap. The slide-removable basket forms a single unit with the chip trap.

Description

Die Erfindung betrifft eine Zerkleinerungsvorrichtung, vorzugsweise zum Zerkleinern von biogenem Material und besonders bevorzugt zum Zerkleinern von Holz, nach dem Oberbegriff des Anspruchs 1.The invention relates to a shredding device, preferably for shredding of biogenic material and particularly preferably for shredding wood, according to the preamble of claim 1.

Es sind bereits sogenannte Schraubenwalzen-Zerkleinerer bekannt, die zwei nebeneinander angeordnete gegenläufig drehende Schnecken aufweisen, die am Umfang teilweise mit Siebkörben abgedeckt sind. Diese Zerkleinerer weisen oberhalb der Schnecken eine Einfüllöffnung für das zu zerkleinernde Gut auf, während unterhalb der Schnecken und der darunter angeordneten Lochblechkörbe ein Auffangraum für das zerkleinerte Gut angeordnet ist. Die zur Mitte hin gegenläufig drehenden Schnecken ziehen das Zerkleinerungsgut selbstständig ein und zerquetschen es. Anschließend wird das Material zwischen den sich gegeneinander verschiebenden Wänden erfasst und zerquetscht, so dass es bricht bzw. zerplatzt. Das entsprechend vorzerkleinerte Material wird über das Lochblech bewegt und teilweise in die Öffnung des Lochsiebs gedrückt, wo es von den nahekommenden Wänden abgeschnitten wird. Das noch nicht ausreichend zerkleinerte Material wird wieder nach oben transportiert und erneut dem Prozess zugeführt. So-called screw roller shredders are already known, the two side by side arranged arranged counter-rotating screws, which on Partially covered with sieve baskets. These shredders point above the screw opens a filling opening for the material to be shredded while a collecting room below the screws and the perforated sheet baskets underneath is arranged for the comminuted material. The counter-rotating towards the middle Snails pull in the crushed material independently and crush it it. Then the material is between those moving against each other Walls captured and crushed so that it breaks or bursts. The appropriately pre-shredded material is moved over the perforated plate and partially pressed into the opening of the perforated screen, where it is coming from the Walls is cut off. The material that has not yet been sufficiently shredded transported back up and fed back into the process.

Gemäß der DE 299 16 171 U ist eine derartige Zerkleinerungsvorrichtung bekannt, bei der die Schnecken aus mit Werkzeugen bestückten Schneckensegmenten zusammengesetzt sind und wobei zwischen und unterhalb der beiden Schnecken eine Leiste mit Schneidaufsätzen, die mit den Schnecken zusammenwirken, verläuft. Bei den vorbekannten Zerkleinerungsvorrichtungen ist das Austauschen der Siebkörbe aufwendig und zeitraubend.Such a shredding device is known from DE 299 16 171 U, in which the screws are composed of screw segments equipped with tools are and with a between and below the two snails Strip with cutting attachments that interact with the screws runs. In the known shredding devices, the screen baskets are replaced complex and time-consuming.

Aufgabe der vorliegenden Erfindung ist es daher, eine gattungsgemäße Zerkleinerungsvorrichtung derart weiterzubilden, dass die Montage bzw. Demontage der Siebkörbe entscheidend vereinfacht wird.The object of the present invention is therefore a generic comminution device to further develop such that the assembly or disassembly of the Sieve baskets is significantly simplified.

Erfindungsgemäß wird diese Aufgabe ausgehend von einer gattungsgemäßen Zerkleinerungsvorrichtung durch die Kombination mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 gelöst.According to the invention, this task is based on a generic comminution device through the combination with the characteristics of the characteristic Part of claim 1 solved.

Demnach sind die unterhalb der als Zerkleinerungswalzen dienenden Schnecken angeordneten Siebkörbe herausnehmbar in einer Siebkorbkassette eingelegt. Dies hat den Vorteil, dass die gesamte Siebkorbkassette als Ganzes im Maschinenrahmen der Zerkleinerungsvorrichtung befestigbar ist und dass durch geeignete Mittel die Siebkörbe in der Siebkorbkassette festlegbar sind. Somit muss nicht jeder einzelne Siebkorb im Grundrahmen befestigt werden. Ein Lösen der Siebkörper aus der Siebkorbkassette kann insbesondere dadurch besonders erleichtert werden, dass die Siebkorbkassette aus ihrer Arbeitsstellung heraus bewegt wird und so eine bessere Zugänglichkeit zu den Siebkörben entsteht, ohne dass die Schnecken aus der Zerkleinerungsvorrichtung entfernt werden müssten.Accordingly, the are below the screws serving as comminution rollers arranged sieve baskets removably inserted in a sieve basket cassette. This has the advantage that the entire screen basket cassette as a whole in the machine frame the shredding device can be fastened and that by suitable means the sieve baskets can be fixed in the sieve basket cassette. So not everyone has to Sieve basket to be fixed in the base frame. A loosening of the sieve body the sieve basket cassette can be particularly facilitated in particular by that the screen basket cassette is moved out of its working position and so one Better access to the sieve baskets is created without the screws the shredding device would have to be removed.

In Fig. 1 ist ein Teil der erfindungsgemäßen Zerkleinerungsvorrichtung 10 gezeigt, wobei dieser Teil hier im wesentlichen aus einem Maschinenrahmen 12 besteht, in welchem zwei in der Fig. 1 nicht mehr dargestellte Schnecken aufnehmbar sind. Diese Schnecken 14 und 16 sind in der Schnittdarstellung gemäß Fig. 5 gezeigt. Im hier vorliegenden Ausführungsbeispiel sind diese Schnecken 14 und 16 hydraulisch angetrieben, wobei der konventionelle Hydraulikantrieb im Einzelnen nicht näher dargestellt ist. Die gegenläufigen Schnecken 14 und 16 haben auch eine gegenläufige Transportrichtung.1 shows part of the comminution device 10 according to the invention, this part consists essentially of a machine frame 12, in which two snails can no longer be shown in FIG. 1. These screws 14 and 16 are shown in the sectional view according to FIG. 5. in the In this embodiment, these screws 14 and 16 are hydraulic driven, whereby the conventional hydraulic drive is not detailed is shown. The opposing screws 14 and 16 also have an opposing one Transport direction.

Wie in Fig. 5 gezeigt, weist die Zerkleinerungsvorrichtung 10 oberhalb der Schnecken 14 und 16 eine Einfüllöffnung 20 auf, die von Seitenwandungen 22 und 24 begrenzt ist.As shown in FIG. 5, the comminution device 10 has above the screws 14 and 16 have a filling opening 20 which is formed by side walls 22 and 24 is limited.

Unterhalb der Schnecken 14 und 16 sind Siebkörbe 26 und 28 angeordnet, die die Schnecken, wie insbesondere wiederum aus Fig. 5 erkennbar, teilweise auf Umfang umgeben. Der Abstand zwischen dem Umfang der Schnecken 14 und 16 und den diese teilweise umgebenden Siebkörbe 26 und 28 ist nur sehr klein. Unterhalb der Siebkörbe 26 und 28 schließt ein Auffangraum 30 für das zu zerkleinernde Gut an.Below the screws 14 and 16, strainer baskets 26 and 28 are arranged, which are the Snails, as can again be seen in particular from FIG. 5, partially on the circumference surround. The distance between the circumference of the screws 14 and 16 and the sieve baskets 26 and 28 which partially surround these are only very small. Below the sieve baskets 26 and 28 enclose a collecting space 30 for the material to be shredded on.

Die Schnecken 14 und 16 bestehen in bekannter Art und Weise aus Schneckensegementen, die mit gezahnten, ebenen Werkzeugen 40 bestückt sind. Die gezahnten, ebenen Werkzeuge sind im hier dargestellten Ausführungsbeispiel an die Schneckensegmente geschraubt. Unterhalb eines Spaltes 18, der zwischen den Schnecken 14 und 16 gebildet ist, verläuft längs zu den Schnecken 14 und 16 eine mehrteilige Leiste 42. Der Aufbau der Leiste ergibt sich ebenfalls beispielsweise aus der Fig. 5, wobei jeweils eine Teilleiste 44 und eine Teilleiste 46 vorgesehen ist, die jeweils wiederum Schneidaufsätze 48 bzw. 50 aufweisen, die mit den Schnecken 14 und 16 zusammenwirken, indem sie in die durch die gezahnten Werkzeuge 40 auf den Schneckensegmenten gebildeten Lücken hineinragen.The screws 14 and 16 consist in a known manner of screw segments, which are equipped with toothed, flat tools 40. The toothed, flat tools are in the embodiment shown here Screw segments screwed. Below a gap 18 between the Screws 14 and 16 is formed, one runs longitudinally to the screws 14 and 16 multi-part bar 42. The structure of the bar also results, for example 5, a partial bar 44 and a partial bar 46 being provided in each case is, which in turn each have cutting attachments 48 and 50, which with the Augers 14 and 16 cooperate by being serrated through the Tools 40 protrude into the gaps formed on the screw segments.

Sowohl die Siebkörbe 26 und 28 wie auch die mehrteilige Leiste 42 sind in einer Siebkorbkassette 60 angeordnet (vgl. die Fig. 2, 3 und 4). Die in der Siebkorbkassette festgelegte Leiste 42 ist über Schrauben 62 lösbar mit der Siebkorbkassette 60 verbunden.Both the screen baskets 26 and 28 as well as the multi-part bar 42 are in one Sieve basket cassette 60 arranged (see. FIGS. 2, 3 and 4). The one in the sieve basket cassette fixed bar 42 is detachable with screws 62 with the screen basket cassette 60 connected.

Die Siebkorbkassette 60 ist als Ganzes über einen Hebel 64 verschwenkbar zur Zerkleinerungsvorrichtung 10 im Grundrahmen 12 gelagert. In Fig. 1 ist die Siebkorbkassette 60 in Arbeitsposition, d. h. eingeschwenkter Stellung gezeigt, während die Siebkorbkassette 60 in den Fig. 2, 3 und 4 jeweils in ausgeschwenkter Position gezeigt ist, in welcher die Siebkörbe 26 und 28 durch einfaches Herausdrehen entnommen bzw. eingelegt werden können. Wie in der Schnittdarstellung gemäß Fig. 5 gezeigt, werden die Siebkörbe 26 und 28 nämlich an einer randseitigen Längsseite durch die unteren Kanten der Leistenteile 44 und 46 der in der Siebkorbkassette 60 mittig längs verlaufenden Leiste 42 gehalten, während sie am gegenüberliegenden freien Rand durch entsprechende Fanghaken 66, die an den Seitenwänden 22 bzw. 24 des Maschinenrahmens 12 befestigt sind, festgehalten werden. Diese Fanghaken 66 werden also erst bei eingeschwenktem Zustand der Siebkorbkassette 60, wie in den Figuren 1 und 5 dargestellt ist, wirksam. Nur in dieser Position sind die Siebkörbe 26 und 28 fixiert. Im eingeschwenkten Zustand, d. h. in ihrer Arbeitsposition (vgl. Fig. 1 bzw. Fig. 5) wird die Siebkorbkassette mit dem Maschinenrahmen durch Verriegelungsbolzen 70 verbunden, wie das aus Fig. 1 hervorgeht. Dabei lassen sich die Verriegelungsbolzen 70 über eine Schubstange 72, die von einer Kolbenzylinderanordnung 74 beaufschlagbar ist, längs in Richtung der Siebkorbkassette 60 hin- und herbewegen, d. h. von einer geschlossenen Stellung, wie sie in Fig. 1 dargestellt ist, in eine geöffnete Stellung entsprechend der Fig. 3 verschieben. Die Verriegelungsbolzen 70 sind auf beiden Seiten der Siebkorbkassette 60 angeordnet.The sieve basket cassette 60 can be pivoted as a whole via a lever 64 Crushing device 10 stored in the base frame 12. In Fig. 1 is the screen basket cassette 60 in working position, d. H. shown pivoted position while the screen basket cassette 60 in FIGS. 2, 3 and 4 each in the pivoted-out position is shown, in which the screen baskets 26 and 28 are removed by simply unscrewing them or can be inserted. As in the sectional view according to FIG. 5, the screen baskets 26 and 28 are namely on an edge-side long side through the lower edges of the strip parts 44 and 46 in the sieve basket cassette 60 held in the middle longitudinal bar 42 while on the opposite free edge through corresponding catch hooks 66 on the side walls 22 and 24 of the machine frame 12 are attached to be held. These catch hooks 66 are thus only when the screen basket cassette is pivoted in 60, as shown in Figures 1 and 5, effective. Only in this position the sieve baskets 26 and 28 are fixed. In the pivoted state, i.e. H. in your The working position (see Fig. 1 and Fig. 5) is the screen basket cassette with the machine frame connected by locking bolts 70, as can be seen in FIG. 1. The locking bolts 70 can be pushed over a push rod 72 can be acted upon by a piston-cylinder arrangement 74, longitudinally in the direction of Move sieve basket cassette 60 back and forth, d. H. from a closed position, as shown in FIG. 1, in an open position corresponding to FIG. 3 move. The locking bolts 70 are on both sides of the screen basket cassette 60 arranged.

Zum Wechseln der Siebkörbe 26 und 28 wird die Siebkorbkassette 60 entriegelt und vorzugsweise über hydraulische Kolbenzylinderanordnungen 76, die einerseits am Grundrahmen 12 und andererseits am Schwenkhebel 64 angelenkt sind, aus der Zerkleinerungsvorrichtung herausgeschwenkt, wie dies in den Figuren 2, 3 und 4 dargestellt ist. Die Drehachsen der Schwenkhebel sind im Grundrahmen und in der Siebkorbkassette parallel zu den Achsen der Schnecken 14 und 16 sowie parallel zu den Verriegelungsachsen 70 angeordnet. Um der Siebkorbkassette 60 eine definierte Schwenkbewegung aufzuprägen wird ein siebkorbkassettenfestes Kulissenrad 80 (vgl Fig. 4) in einer maschinenrahmenfesten Kulissenbahn 82 während der Schwenkbewegung geführt. So kann durch Verschwenken der Schwenkhebel 64 und zwangsweise aufgeprägter überlagerter Schwenkbewegung der Siebkorbkassette die gesamte Siebkorbkassette in eine schräge Lage verschwenkt werden, wie sie beispielsweise in den Fig. 3 und 4 dargestellt ist, die eine bedienerfreundliche Positionierung der Siebkörbe 26 und 28 erlaubt. Hierdurch können die Siebkörbe 14 und 16 leicht herausgenommen und wiedereingesetzt werden.To change the strainer baskets 26 and 28, the strainer basket cassette 60 is unlocked and preferably via hydraulic piston-cylinder assemblies 76, on the one hand are articulated on the base frame 12 and on the other hand on the pivot lever 64 the comminution device pivoted out, as shown in Figures 2, 3 and 4 is shown. The axes of rotation of the swivel levers are in the base frame and in the sieve basket cassette parallel to the axes of the screws 14 and 16 and parallel arranged to the locking axes 70. Around the screen basket cassette 60 a A pivoting wheel fixed to the sieve basket is impressed on the defined pivoting movement 80 (see Fig. 4) in a machine frame fixed backdrop track 82 during the pivoting movement. So by swiveling the swivel lever 64 and forcibly imposed superimposed pivoting movement of the screen basket cassette the entire screen basket cassette can be swiveled into an inclined position, 3 and 4, for example, which is a user-friendly Positioning of the strainer baskets 26 and 28 allowed. This allows the sieve baskets 14 and 16 can be easily removed and reinserted.
