Definitions
- the invention relates to a grinder for cutting material of different consistency to be shredded, in particular a meat grinder, with a conveying device for transporting the material to be fed into the conveying device via a cutting device into a conveying opening, the cutting device essentially consisting of a perforated disk and one in the conveying direction in front of the perforated disk cutting knife located there.
- a long conveying path in the conveyor device to the cutting device is advantageous.
- the material to be cut arrives in the area of the conveying device, it is subject to a conveying pressure generated by it, and as the conveying path increases, an ever higher pressure builds up in the material to be cut, with a maximum directly in front of the perforated disk; it leads to a high shredding performance because the material to be shredded by the cutting knife with this high pressure is conveyed through the perforated disc.
- a wolf intended for such a material to be sliced must be of a different nature: the material to be sliced may only be subjected to a short conveying path to the cutting device so that the pressure in the material to be sliced remains at a low level.
- the path remaining in the grinder up to the conveying opening only plays a subordinate role after the processing of the material to be cut in the cutting device, because the material which is still frozen does not tend to cake and therefore cannot smear.
- a wolf of the type described in the introduction is therefore usually only designed and usable for one of the two different types of material to be cut. Attempts have also been made to remedy this deficiency and to design a wolf so that it can be used universally; in addition there is its pressure zone - ie the conveying path in the conveying device and the subsequent cutting path in the Cutting device until the material to be cut emerges from the perforated disc - has been set to an average value which, of course, can only be inadequately adapted to the different material to be cut. Such a compromise in the design of the pressure zone can understandably not guarantee optimal treatment of differently structured material to be cut.
- the object of the invention is therefore to design such a wolf of the type described above in such a way that it can be prepared for very different items to be cut, and in such a way that a high-quality end product can be produced from each item to be cut, of this quality otherwise can only be achieved with one device that is specially designed for the particular material to be cut and is not suitable for another.
- the object is achieved in that a widening the conveying path of the material to be cut and easily removable and re-insertable from the wolf housing is provided in a wolf housing between the conveyor and the cutting device.
- the pressure zone of the grinder can be optimally adapted to very different items to be cut, since different intermediate pieces can be used to ensure that the conveying path is changed in accordance with the respective items to be cut. Since the wolf otherwise remains unchanged, the perforated disk which is sunk without the intermediate piece in the wolf moves more or less in the direction of the conveying opening, thereby shortening the conveying path in the conveying direction after the perforated disk.
- the invention can be embodied particularly simply on a wolf in which the conveying device and the cutting device are provided in alignment in the tubular wolf housing in a common axis, the cutting device by means of a threaded connection with the wolf housing on its open end face and provided with the conveying opening for the finished product Clamping bushing is axially clampable and the intermediate piece has a coaxial spacing bushing which can be inserted into the wolf housing.
- Such a spacer bushing can be designed as an easy-to-produce rotating part, it being particularly advantageous if the spacer bushing - abutting a stop collar of the wolf housing for the cutting device - can be inserted into the wolf housing and is radially supported on its inner casing; its installation and removal is easy, so that neither specialist knowledge nor special manual dexterity is required.
- the conveying device has a screw conveyor which, together with the cutting knife, is applied in a rotationally fixed manner on a drive shaft operated by a rotary drive.
- the screw conveyor consists of a first screw segment which remains permanently on the drive shaft and a second, there is a screw segment belonging to the intermediate piece and easily removable together with the spacer bush, so that a corresponding delivery pressure is exerted up to the perforated disk, valid whether this is provided at the end of a long or a short funding path.
- the screw conveyor is guided radially and securely together with the drive shaft when the first screw segment with its outer lateral surface is guided on the inner jacket of the wolf housing, which has a cylindrical cylindrical envelope, and the second screw segment with its outer jacket surface is guided on a comparable inner jacket of the spacer sleeve ; it is best if the diameter of the second screw segment is equal to or smaller than the diameter of the first, so that the spacer bush does not require a particularly drastic reduction in the wall thickness on the (surrounding) wolf housing.
- a length compensation takes place in a simple manner in that at least one coaxial spacer ring can be inserted between the clamping bush and the perforated disk when the intermediate piece is removed from the wolf; it can easily be set up so that the clamping bush remains in the same axial assignment to the open face of the wolf housing.
- the invention accordingly ensures, with very few additional, simply shaped and easy-to-use components, that a wolf of the type described at the outset can be used in a variety of ways and can be used practically for all items to be cut, without affecting the quality of the end product.
- Fresh or frozen meat can be chopped just like soft or very firm cheese or the like; any material to be cut is suitable for processing in such a grinder if only the pressure Zone dimensioned accordingly and the position of the perforated disc in relation to the conveyor is made to match.
- FIG. 2 shows an enlarged longitudinal section through FIG. 1 through the working area of the wolf for processing a relatively soft
- a tubular wolf housing 1 according to FIG. 1, which can be connected to the other assemblies of the wolf by means of a holding flange 26, in particular with a rotary drive for a screw conveyor 3 and thus also for a housing accommodated in a drive housing Drive shaft 2, with the aid of which both a conveyor device 4 provided with a screw conveyor 3 and a cutting device 5 are driven.
- the conveying device 4 also includes a helical groove 7 which is recessed into the inner casing 6 of the wolf housing 1 in the length of the conveying screw 3 and which enhances the conveying effect for the product.
- the slope of the screw conveyor 3 is so directed that a material to be cut brought into the area of the conveyor 4 is transported in a conveying direction 8 which coincides with an axis 9 of the drive shaft 2 common to the wolf housing 1, the conveyor 4 and the cutting device 5.
- the cutting device 5 consists of a cutting knife 10 which is rotationally connected to the drive shaft 2 and consists of radially directed cutting blades 12 attached to a knife hub 11 and a perforated disk 13 which is guided on the inner casing 6 in a rotational test.
- the bearing ring 15, like the perforated disk 13 and the disk 14, is also axially displaceable in the wolf housing 1 and transmits a clamping force exerted by a clamping bush 27 to the inserted components of the wolf, which - apart from the screw conveyor 3 and the cutting knife 10 - has an axially parallel, groove-shaped groove 17 which, together with a knob on the inner jacket 6 omitted in the drawing, form a rotation lock in the usual way.
- the clamping bush 27 is connected by means of a clamping thread 18 to the wolf housing 1 on its open end face 23 and is provided with a conveying opening 19 for the finished product.
- the screw conveyor 3 is made in two parts - in the axial direction - and consists of a first screw segment 20 and an axially immediately adjoining second screw segment 21, which is surrounded radially and in the installed state by a spacer bushing 22 which, together with the screw segment 21, forms an intermediate piece 21, 22 which is between the first screw segment 20 and the Disk 14 inserted and can be removed again.
- FIGS. 2, 3, illustrate two different forms of use of the wolf according to the invention.
- the wolf is equipped with the intermediate piece 21, 22, which, extending the conveying path 8 in the conveying device 4, has displaced the cutting device 5 far in the direction of the conveying opening 19, so that the perforated disk 13 is close to the conveying opening 19th is located and the finished product leaves the grinder immediately after comminution, while on the other hand the conveying path 8 for the material to be cut is extended by the axial length 1 of the intermediate piece 21, 22.
- the spacer bushing 22 does not necessarily have to be as long as the second screw segment 21, as is shown in FIG.
- a spacer ring 28 which is non-rotatable on the wolf housing 1 and whose axial length 1 ′ is approximately the same as the length 1 of the intermediate piece 21, 22 serves for length compensation and has been inserted between the bearing ring 15 and the clamping bush 27. Otherwise the wolf remains unchanged.
Abstract
The invention concerns a chopper used for chopping up, for example fresh or frozen meat. Said chopper is provided with a cutting device (5) capable of moving axially in the chopper (1) body, such that the forward stroke, and therefore the pressing zone, can be adapted to the corresponding material to be cut. For this purpose, said chopper comprises an intermediate part (21, 22) capable of being mounted removable.
Description
Wolf wolf
Bescnreipunq:Description:
Die Erfindung betrifft einen Wolf für zu zerkleinerndes Schneidgut unterschiedlicher Konsistenz, insbesondere einen Fleischwolf, mit einer Fördereinrichtung für den Transport des in die Fördereinrichtung eingespeisten Schneidgutes über eine Schneideinrichtung in eine Förderöffnung, wobei die Schneideinrichtung im wesentlichen aus einer Lochscheibe und einem in Förderrichtung vor der Lochscheibe befindlichen Schneidmesser besteht.The invention relates to a grinder for cutting material of different consistency to be shredded, in particular a meat grinder, with a conveying device for transporting the material to be fed into the conveying device via a cutting device into a conveying opening, the cutting device essentially consisting of a perforated disk and one in the conveying direction in front of the perforated disk cutting knife located there.
Beim Zerkleinern von Schneidgut mit einer Konsistenz wie bei Frischfleisch in einem Wolf dieser Art mit noch ge- ringerer Konsistenz oder ähnlichen Produkten mit geringeren Konsistenzen ist ein langer Förderweg in der Fördereinrichtung bis zu der Schneideinrichtung von Vorteil. Sobald das Schneidgut in den Bereich der Fördereinrichtung gelangt, unterliegt es einem von dieser generierten Förderdruck, und mit zunehmendem Förderweg baut sich in dem Schneidgut ein immer höherer Druck auf mit einem Maximum unmittelbar vor der Lochscheibe; er führt zu einer großen Zerkleinerungsleistung, weil das von dem Schneid- messer zerkleinerte Schneidgut mit diesem hohem Druck
durch die Lochscheibe gefördert wird. Gleichzeitig ist es aber erforderlich, daß das aus der Lochscheibe austretende Schneidgut möglichst unmittelbar hinter der Lochscheibe aus dem Bereich des Wolfes entnommen wird, damit dort eine Engführung des Fertigproduktes nicht dazu führt, daß das Schneidgut wieder zusammengepreßt wird und verschmiert, sondern daß es statt dessen locker bleibt.When chopping sliced material with a consistency such as fresh meat in a wolf of this type with an even lower consistency or similar products with lower consistencies, a long conveying path in the conveyor device to the cutting device is advantageous. As soon as the material to be cut arrives in the area of the conveying device, it is subject to a conveying pressure generated by it, and as the conveying path increases, an ever higher pressure builds up in the material to be cut, with a maximum directly in front of the perforated disk; it leads to a high shredding performance because the material to be shredded by the cutting knife with this high pressure is conveyed through the perforated disc. At the same time, however, it is necessary that the material to be cut emerging from the perforated disc is removed from the area of the wolf as directly as possible behind the perforated disc, so that a tight fit of the finished product does not result in the material to be pressed and smeared again, but instead instead remains loose.
Mit einem solchen Wolf ist hingegen die Verarbeitung von festerem Schneidgut wie etwa von Gefrierfleisch nur eingeschränkt möglich. Das in Partikeln bestimmter Größe der Fördereinrichtung zugeführte Schneidgut neigt dazu, daß unter zu hohem Förderdruck die Partikel wieder zusammenfrieren und die Fördereinrichtung blockieren, so daß sie nicht mehr zerkleinert werden können. Deshalb muß ein für ein derartiges Schneidgut bestimmter Wolf anders beschaffen sein: das Schneidgut darf bei ihm nur einem kurzen Förderweg bis in die Schneideinrichtung unterzogen werden, damit der Druck im Schneidgut auf niedrigem Niveau verbleibt. Hingegen spielt der in dem Wolf bis zu der Förderöffnung verbleibende Weg im Anschluß an die Verarbeitung des Schneidgutes in der Schneideinrichtung nur eine untergeordnete Rolle, weil das nach wie vor gefrorene Schneidgut nicht zum Zusammenbacken neigt und deshalb nicht' verschmieren kann.With such a wolf, however, the processing of firmer sliced goods such as frozen meat is only possible to a limited extent. The material to be cut, which is supplied to the conveyor in particles of a certain size, tends to freeze the particles together again under excessive delivery pressure and block the conveyor, so that they can no longer be comminuted. For this reason, a wolf intended for such a material to be sliced must be of a different nature: the material to be sliced may only be subjected to a short conveying path to the cutting device so that the pressure in the material to be sliced remains at a low level. On the other hand, the path remaining in the grinder up to the conveying opening only plays a subordinate role after the processing of the material to be cut in the cutting device, because the material which is still frozen does not tend to cake and therefore cannot smear.
Ein Wolf der eingangs näher bezeichneten Art ist deshalb in der Regel nur für eine der beiden verschiedenen Sorten Schneidgutes ausgelegt und zu gebrauchen. Es ist auch schon versucht worden, diesem Mangel abzuhelfen und einen Wolf so auszulegen, daß er universell anwendbar ist; dazu ist seine Druckzone - d.h. der Förderweg in der Fördereinrichtung sowie der anschließende Schneidweg in der
Schneideinrichtung bis zum Austritt des Schneidgutes aus der Lochscheibe - auf einen Mittelwert gestellt worden, der dem unterschiedlichen Schneidgut natürlich jeweils nur unzureichend angepaßt sein kann. Ein solcher Kompro- miß bei der Ausgestaltung der Druckzone kann eine optimale Behandlung verschieden strukturierten Schneidgutes verständlicherweise nicht gewährleisten.A wolf of the type described in the introduction is therefore usually only designed and usable for one of the two different types of material to be cut. Attempts have also been made to remedy this deficiency and to design a wolf so that it can be used universally; in addition there is its pressure zone - ie the conveying path in the conveying device and the subsequent cutting path in the Cutting device until the material to be cut emerges from the perforated disc - has been set to an average value which, of course, can only be inadequately adapted to the different material to be cut. Such a compromise in the design of the pressure zone can understandably not guarantee optimal treatment of differently structured material to be cut.
Die Erfindung hat sich deshalb die Aufgabe gestellt, ei- nen derartigen Wolf der oben beschriebenen Bauart so auszubilden, daß er für ganz unterschiedliches Schneidgut hergerichtet werden kann und zwar so, daß dann aus jedem Schneidgut ein qualitativ hochwertiges Endprodukt herstellbar ist, welches in dieser Qualität ansonsten nur jeweils mit einem Gerät erreicht werden kann, das speziell für das jeweilige Schneidgut ausgelegt und für ein anderes hingegen nicht geeignet ist.The object of the invention is therefore to design such a wolf of the type described above in such a way that it can be prepared for very different items to be cut, and in such a way that a high-quality end product can be produced from each item to be cut, of this quality otherwise can only be achieved with one device that is specially designed for the particular material to be cut and is not suitable for another.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß in einem Wolfsgehäuse zwischen der Fördereinrichtung und der Schneideinrichtung eine den Förderweg des Schneidgutes verlängerndes und aus dem Wolfsgehäuse leicht entfern- und wiedereinsetzbares Zwischenstück vorgesehen ist. Auf diese einfache Weise kann die Druckzone des Wolfes ganz unterschiedlichem Schneidgut optimal angepaßt werden, denn es kann mit unterschiedlichen Zwischenstücken dafür gesorgt werden, daß der Förderweg dem jeweiligen Schneidgut entsprechend verändert wird. Da der Wolf ansonsten unverändert bleibt, wandert die ohne das Zwischenstück in dem Wolf versenkt angeordnete Lochscheibe mehr oder weniger in Richtung der Förderöffnung, dabei den Förderweg in Förderrichtung nach der Lochscheibe verkürzend.
Besonders einfach kann die Erfindung an einem Wolf ausgebildet werden, bei dem die Fördereinrichtung und die Schneideinrichtung in dem rohrförmigen Wolfsgehäuse fluchtend in einer gemeinsamen Achse vorgesehen sind, die Schneideinrichtung mittels einer mit dem Wolfsgehäuse an dessen offener Stirnseite gewindeverbundenen, mit der Förderöffnung für das Fertigprodukt versehenen Spannbuchse axial spannbar ist und das Zwischenstück eine in das Wolfsgehäuse einsteckbare, koaxiale Distanzbuchse aufweist. Eine solche Distanzbuchse kann als einfach herzustellendes Drehteil ausgeführt werden, wobei es besonders günstig ist, wenn die Distanzbuchse - an einem Anschlagbund des Wolfsgehäuses für die Schneideinrichtung anschlagend - in das Wolfsgehäuse einsteckbar und an dessen Innenmantel radial gelagert ist; sein Ein- und Ausbau gestaltet sich dadurch einfach, so daß dazu weder Fachkenntnisse noch besondere handwerkliche Geschicklichkeit erforderlich sind.According to the invention the object is achieved in that a widening the conveying path of the material to be cut and easily removable and re-insertable from the wolf housing is provided in a wolf housing between the conveyor and the cutting device. In this simple manner, the pressure zone of the grinder can be optimally adapted to very different items to be cut, since different intermediate pieces can be used to ensure that the conveying path is changed in accordance with the respective items to be cut. Since the wolf otherwise remains unchanged, the perforated disk which is sunk without the intermediate piece in the wolf moves more or less in the direction of the conveying opening, thereby shortening the conveying path in the conveying direction after the perforated disk. The invention can be embodied particularly simply on a wolf in which the conveying device and the cutting device are provided in alignment in the tubular wolf housing in a common axis, the cutting device by means of a threaded connection with the wolf housing on its open end face and provided with the conveying opening for the finished product Clamping bushing is axially clampable and the intermediate piece has a coaxial spacing bushing which can be inserted into the wolf housing. Such a spacer bushing can be designed as an easy-to-produce rotating part, it being particularly advantageous if the spacer bushing - abutting a stop collar of the wolf housing for the cutting device - can be inserted into the wolf housing and is radially supported on its inner casing; its installation and removal is easy, so that neither specialist knowledge nor special manual dexterity is required.
Es ist besonders zweckmäßig, wenn die Fördereinrichtung eine Förderschnecke aufweist, die zusammen mit dem Schneidmesser drehfest auf einer von einem Drehantrieb betriebenen Antriebswelle aufgebracht ist. Bei einer solchen Anordnung kann in einfacher Weise dafür gesorgt wer- den, daß der ' Transport des Schneidgutes bis in die unmittelbare Nähe der Schneideinrichtung schonend durchgeführt wird, wenn die Förderschnecke aus einem ersten, dauerhaft auf der Antriebswelle verbleibenden Schnecken- Segment und einem zweiten, zu dem Zwischenstück gehören- den und zusammen mit der Distanzbuchse leicht entfernbaren Schnecken-Segment besteht, so daß ein entsprechender Förderdruck bis zu der Lochscheibe ausgeübt wird, gleich-
gültig, ob diese am Ende eines langen oder eines kurzen Förderweges vorgesehen ist.It is particularly expedient if the conveying device has a screw conveyor which, together with the cutting knife, is applied in a rotationally fixed manner on a drive shaft operated by a rotary drive. With such an arrangement, it can be ensured in a simple manner that the transport of the material to be cut is carried out gently into the immediate vicinity of the cutting device if the screw conveyor consists of a first screw segment which remains permanently on the drive shaft and a second, there is a screw segment belonging to the intermediate piece and easily removable together with the spacer bush, so that a corresponding delivery pressure is exerted up to the perforated disk, valid whether this is provided at the end of a long or a short funding path.
Die Förderschnecke wird zusammen mit der Antriebswelle radial sicher geführt, wenn das erste Schnecken-Segment mit seiner äußeren Mantelfläche an dem den Schneckengang kreiszylindrisch umhüllenden Innenmantel des Wolfsgehäu- seε und das zweite Schnecken-Segment mit seiner äußeren Mantelfläche an einem vergleichbaren Innenmantel der Distanzbuchse geführt ist; es ist am besten, wenn der Durchmesser des zweiten Schnecken-Segmentes gleich groß oder kleiner ist als der Durchmesser des ersten, so daß die Distanzbuchse keine besonders drastische Verminderung der Wandstärke an dem (umgebenden) Wolfsgehäuse erfordert.The screw conveyor is guided radially and securely together with the drive shaft when the first screw segment with its outer lateral surface is guided on the inner jacket of the wolf housing, which has a cylindrical cylindrical envelope, and the second screw segment with its outer jacket surface is guided on a comparable inner jacket of the spacer sleeve ; it is best if the diameter of the second screw segment is equal to or smaller than the diameter of the first, so that the spacer bush does not require a particularly drastic reduction in the wall thickness on the (surrounding) wolf housing.
Ein Längenausgleich findet dabei in einfacher Weise statt, indem zwischen der Spannbuchse und der Lochscheibe mindestens ein koaxialer Distanzring dann einfügbar ist, wenn das Zwischenstück aus dem Wolf entfernt ist; es läßt sich leicht so einrichten, daß die Spannbuchse zu der offenen Stirnseite des Wolfsgehäuses in gleicher axialen Zuordnung verbleibt.A length compensation takes place in a simple manner in that at least one coaxial spacer ring can be inserted between the clamping bush and the perforated disk when the intermediate piece is removed from the wolf; it can easily be set up so that the clamping bush remains in the same axial assignment to the open face of the wolf housing.
Die Erfindung' stellt dementsprechend mit ganz wenigen zusätzlichen, einfach geformten und leicht zu handhabenden Bauteilen sicher, daß ein Wolf der eingangs bezeichneten Art vielfältiger nutzbar und praktisch für alles Schneidgut einsetzbar ist, ohne daß die Qualität des Endproduktes berührt wäre. So ist frisches oder gefrorenes Fleisch genauso zerkleinerbar wie weicher oder sehr fester Käse oder dergleichen; jedes Schneidgut ist für die Bearbeitung in einem solchen Wolf geeignet, wenn nur die Druck-
zone entsprechend bemessen und die Lage der Lochscheibe in Bezug auf die Fördereinrichtung dazu passend hergestellt wird.The invention accordingly ensures, with very few additional, simply shaped and easy-to-use components, that a wolf of the type described at the outset can be used in a variety of ways and can be used practically for all items to be cut, without affecting the quality of the end product. Fresh or frozen meat can be chopped just like soft or very firm cheese or the like; any material to be cut is suitable for processing in such a grinder if only the pressure Zone dimensioned accordingly and the position of the perforated disc in relation to the conveyor is made to match.

sämtlich in schematisch vereinfachter Darstellung.all in a schematically simplified representation.
An einem Wolf nach der Erfindung befindet sich entsprechend Fig.l zunächst ein rohrförmiges Wolfsgehäuse 1, das mittels eines Halteflansches 26 mit den übrigen Baugruppen des Wolfes verbunden werden kann, insbesondere mit einem in einem Antriebsgehäuse untergebrachten Drehantrieb für eine Förderschnecke 3 und damit auch für eine Antriebswelle 2, mit deren Hilfe sowohl eine mit einer Förderschnecke 3 versehene Fördereinrichtung 4 als auch eine Schneideinrichtung 5 angetrieben werden. Zu der Fördereinrichtung 4 gehört weiterhin eine in den Innen- mantel 6 des Wolfsgehäuses 1 in Länge der Förderschnecke 3 eingetiefte schraubenförmige Rille 7 , welche die Förderwirkung für das Produkt verstärkt.
Die Steigung der Förderschnecke 3 ist so gerichtet, daß ein in den Bereich der Fördereinrichtung 4 verbrachtes Schneidgut in einer Förderrichtung 8 transportiert wird, die mit einer dem Wolfsgehäuse 1, der Fördereinrichtung 4 und der Schneideinrichtung 5 gemeinsamen Achse 9 der Antriebswelle 2 übereinstimmt.On a wolf according to the invention there is first a tubular wolf housing 1 according to FIG. 1, which can be connected to the other assemblies of the wolf by means of a holding flange 26, in particular with a rotary drive for a screw conveyor 3 and thus also for a housing accommodated in a drive housing Drive shaft 2, with the aid of which both a conveyor device 4 provided with a screw conveyor 3 and a cutting device 5 are driven. The conveying device 4 also includes a helical groove 7 which is recessed into the inner casing 6 of the wolf housing 1 in the length of the conveying screw 3 and which enhances the conveying effect for the product. The slope of the screw conveyor 3 is so directed that a material to be cut brought into the area of the conveyor 4 is transported in a conveying direction 8 which coincides with an axis 9 of the drive shaft 2 common to the wolf housing 1, the conveyor 4 and the cutting device 5.
Die Schneideinrichtung 5 besteht aus einem mit der Antriebswelle 2 drehverbundenen Schneidmesser 10 aus radial gerichteten, an einer Messernabe 11 ansetzenden Schneidklingen 12 und einer Lochscheibe 13, die an dem Innenmantel 6 drehtest geführt ist. Eine in gleicher Weise an dem Innenmantel 6 drehfeste, großflächig durchbrochene Scheibe 14 trennt die Förderschnecke 3 von dem Schneid- messer 10, und ein wiederum drehfest an dem Innenmantel 6 geführter Lagerring 15 dient mit seiner Lagernabe 16 zur Lagerung der Antriebswelle 2; der Lagerring 15 ist wie die Lochscheibe 13 und die Scheibe 14 auch in dem Wolfsgehäuse 1 axial verschiebbar und überträgt eine von einer Spannbuchse 27 ausgeübte Spannkraft auf die eingesteckten Bauteile des Wolfes, die - außer der Förderschnecke 3 und dem Schneidmesser 10 - eine achsparallele rillenförmige Nut 17 aufweisen, die zusammen mit einem in der Zeichnung weggelassenen Noppen auf dem Innenmantel 6 in fachübli- eher Weise eirte Drehsicherung bilden.The cutting device 5 consists of a cutting knife 10 which is rotationally connected to the drive shaft 2 and consists of radially directed cutting blades 12 attached to a knife hub 11 and a perforated disk 13 which is guided on the inner casing 6 in a rotational test. A disk 14, which is rotatably and extensively perforated on the inner jacket 6 in the same way, separates the screw conveyor 3 from the cutting knife 10, and a bearing ring 15, which is in turn rotatably guided on the inner jacket 6, serves with its bearing hub 16 for mounting the drive shaft 2; The bearing ring 15, like the perforated disk 13 and the disk 14, is also axially displaceable in the wolf housing 1 and transmits a clamping force exerted by a clamping bush 27 to the inserted components of the wolf, which - apart from the screw conveyor 3 and the cutting knife 10 - has an axially parallel, groove-shaped groove 17 which, together with a knob on the inner jacket 6 omitted in the drawing, form a rotation lock in the usual way.
Die Spannbuchse 27 ist mittels eines Spanngewindes 18 mit dem Wolfsgehäuse 1 an dessen offener Stirnseite 23 verbunden und mit einer Förderöffnung 19 für das Fertigpro- dukt versehen.The clamping bush 27 is connected by means of a clamping thread 18 to the wolf housing 1 on its open end face 23 and is provided with a conveying opening 19 for the finished product.
Die Förderschnecke 3 ist - in Achsrichtung - zweigeteilt ausgeführt und besteht aus einem ersten Schnecken-Segment
20 und einem axial unmittelbar anschließenden zweiten Schnecken-Segment 21, welches radial und im eingebauten Zustand von einer Distanzbuchse 22 umgeben ist, die zusammen mit dem Schnecken-Segment 21 ein Zwischenstück 21,22 bildet, welches zwischen dem ersten Schnecken-Segment 20 und der Scheibe 14 eingefügt und auch wieder entnommen werden kann.The screw conveyor 3 is made in two parts - in the axial direction - and consists of a first screw segment 20 and an axially immediately adjoining second screw segment 21, which is surrounded radially and in the installed state by a spacer bushing 22 which, together with the screw segment 21, forms an intermediate piece 21, 22 which is between the first screw segment 20 and the Disk 14 inserted and can be removed again.
Die Einzelheiten der Anordnung kommen am besten in den Fig.2, 3 zum Ausdruck, die zwei unterschiedliche Ge- brauchsformen des erfindungεge äßen Wolfes veranschaulichen.The details of the arrangement are best expressed in FIGS. 2, 3, which illustrate two different forms of use of the wolf according to the invention.
In der Fig.2 ist der Wolf mit dem Zwischenstück 21,22 ausgerüstet, das, den Förderweg 8 in der Fördereinrichtung 4 verlängernd, die Schneideinrichtung 5 weit in Richtung auf die Förderöffnung 19 verschoben hat, so daß sich die Lochscheibe 13 nahe der Förderöffnung 19 befindet und das Fertigprodukt unmittelbar nach dem Zerklei- nern den Wolf verläßt, während andererseits der Förderweg 8 für das Schneidgutes um die axiale Länge 1 des Zwischenstückes 21,22 verlängert ist. Die Distanzbuchse 22 muß nicht notwendig genauso lang sein wie das zweite Schnecken-Segment 21, wie das in der Fig.2 ausgeführt ist; eine ungefähre Übereinstimmung genügt und kann durch die axiale Lage eines Anschlagbundes 24 im Zuge des Innenmantels 6 des Wolfsgehäuse 1 für die Distanzbuchse 22 und des Stirnendes 25 des ersten Schnecken-Segmentes 20 so beeinflußt werden, daß beide Teile des Zwischen- Stückes 21,22 in Förderrichtung 8 etwa bündig enden. Es ist zweckmäßig, wenn die schraubenförmige Rille 7b in dem Wolfgehäuεe 1 mit der Rille 7a in dem Zwischenstück 22 die gleichen geometrischen Abmessungen hat.
Während die Anordnung der Fig.2 für relativ weiches Schneidgut geeignet ist, wird für festes Schneidgut besser diejenige der Fig.3 verwendet. Das Zwischenstück 21,22 ist aus dem Wolfsgehäuse 1 entfernt worden, so daß die Schneideinrichtung 5 weit in dessen Inneres gerückt ist und die Scheibe 14 nunmehr an dem Anschlagbund 24 anliegt. Der Förderweg 8 ist beträchtlich verkürzt. Ein an dem Wolfsgehäuse 1 drehfester Distanzring 28, dessen axiale Länge 1' der Länge 1 des Zwischenstückes 21,22 etwa gleich ist, dient zum Längenausgleich und ist zwischen dem Lagerring 15 und der Spannbuchse 27 eingefügt worden. Im übrigen bleibt der Wolf unverändert.
2, the wolf is equipped with the intermediate piece 21, 22, which, extending the conveying path 8 in the conveying device 4, has displaced the cutting device 5 far in the direction of the conveying opening 19, so that the perforated disk 13 is close to the conveying opening 19th is located and the finished product leaves the grinder immediately after comminution, while on the other hand the conveying path 8 for the material to be cut is extended by the axial length 1 of the intermediate piece 21, 22. The spacer bushing 22 does not necessarily have to be as long as the second screw segment 21, as is shown in FIG. 2; an approximate match is sufficient and can be influenced by the axial position of a stop collar 24 in the course of the inner shell 6 of the wolf housing 1 for the spacer bush 22 and the front end 25 of the first screw segment 20 so that both parts of the intermediate piece 21, 22 in Conveying direction 8 end approximately flush. It is expedient if the helical groove 7b in the wolf housing 1 with the groove 7a in the intermediate piece 22 has the same geometric dimensions. While the arrangement of FIG. 2 is suitable for relatively soft material to be cut, that of FIG. 3 is better used for solid material to be cut. The intermediate piece 21, 22 has been removed from the wolf housing 1, so that the cutting device 5 has moved far into the interior thereof and the disk 14 now lies against the stop collar 24. The conveyor path 8 is considerably shortened. A spacer ring 28 which is non-rotatable on the wolf housing 1 and whose axial length 1 ′ is approximately the same as the length 1 of the intermediate piece 21, 22 serves for length compensation and has been inserted between the bearing ring 15 and the clamping bush 27. Otherwise the wolf remains unchanged.
