Abstract

In a mixing device for liquid manure, having a bearing frame, a shaft (6) and a propeller (12), in order to make the mode of operation of a cutting tool independent of the axial play of the propeller bearing to avoid having to readjust and regrind the blades (15), it is proposed to provide at least one two-pronged fork (16) and at least one finger (15) as the cutting tool, the finger passing through between the fork prongs. Preferably, the fork is formed as a double blade and fixed to the bearing frame, while the fingers are revolving single blades (15). Advantageously, commercially available cutter blades intended for the shearing bars of mowing machines are used. <IMAGE>

Description

Die Erfindung betrifft eine Rührvorrichtung für Flüssigmist mit einem Lagergestell, einer in diesem gelagerten Welle und einem an der Welle befestigten Propeller, sowie mit einer Schneidvorrichtung, die mindestens ein am Lagergestell gehaltenes Messer aufweist. Meist ist das Lagergestell ein langgestrecktes Rohr, das an seinem Ende eine nach unten gerichtete spornartige Stütze aufweist, die dazu dient, die Propellerblätter vor einem direkten Kontakt mit dem Boden der Flüssigmistgrube zu schützen. Der Antrieb des Rührpropellers erfolgt häufig über eine Gelenkwelle von der Zapfwelle eines landwirtschaftlichen Schleppers aus.The invention relates to a stirring device for liquid manure with a storage rack, a shaft mounted therein and a propeller attached to the shaft, and with a cutting device which has at least one knife held on the storage rack. Mostly the storage rack is an elongated tube that has a downward spur-like support at its end that serves to protect the propeller blades from direct contact with the bottom of the liquid manure pit. The propeller is often driven by a PTO shaft from the PTO of an agricultural tractor.

Flüssigmist aus landwirtschaftlichen Betrieben enthält je nach der Beschaffenheit des verwendeten Streugutes viel­fach langfaserige Bestandteile, Grashalme und vor allem auch lange Strohhalme. Diese sind sehr zäh und werden von den rotierenden Propellerblättern nicht durchgeschnitten, sondern haben die Tendenz, sich über die vorauseilenden Kanten der Blätter zu hängen und um den Propeller herum zu schlingen. Dadurch wird die Rührleistung stark vermindert. Frisches Langstroh im Flüssigmist muß vor dem Ausbringen auch deshalb gekürzt werden, um Verstopfungen in Pumpen und Dungverteilern zu verhindern. Auch Kunststoffschnüre und Stricke müssen zerkleinert werden.Depending on the nature of the spreading material, liquid manure from agricultural businesses often contains long-fiber components, blades of grass and, above all, long straws. These are very tough and are not cut by the rotating propeller blades, but tend to hang over the leading edges of the blades and loop around the propeller. This greatly reduces the stirring power. Fresh long straw in liquid manure must also be shortened before spreading to prevent blockages in pumps and manure spreaders. Plastic cords and ropes also have to be shredded.

Es ist jedoch, beispielsweise aus DE-GM 86 21 176, bekannt, mit Hilfe einer in der Nähe des Propellers angebrachten Schneidvorrichtung die langfaserigen Teile des Rührgutes in Stücke zu trennen, so daß sie sich nicht mehr am Propeller festsetzen können. Aus der genannten Schrift ist es bekannt, an dem Sporn des Lagergestells ein Messer in geringem Abstand vom Rührflügel anzuordnen, wobei "geringer Abstand" bedeutet, daß das feststehende Messer und die einzelnen Rührflügel fast wie eine Schere zusammenwirken können. Es ist auch bekannt, die Flügelkanten, welche mit dem Messer zusammenwirken, zu schärfen und als Schneiden auszubilden.However, it is known, for example from DE-GM 86 21 176, to separate the long-fiber parts of the agitated material into pieces with the aid of a cutting device attached in the vicinity of the propeller, so that they can no longer adhere to the propeller. From the cited document it is known to arrange a knife on the spur of the storage rack at a short distance from the impeller, where "close spacing" means that the fixed knife and the individual impellers can work together almost like scissors. It is also known to sharpen the wing edges, which interact with the knife, and to form them as cutting edges.

Scherenartig wirkende Schneidvorrichtungen haben jedoch den grundsätzlichen Nachteil, daß die Messer sehr genau gegeneinander angestellt werden müssen und demgemäß die Propellerlager kein Spiel haben dürfen. Außerdem stumpfen solche in geringstem Abstand aneinander vorbeilaufende Messer außerordentlich schnell ab. Hierfür sind nicht nur Fremdkörper, die sich zwischen die Messer klemmen können, verantwortlich, sondern insbesondere der im Flüssigmist stets enthaltene Sand. Weidetiere bringen Sand mit den Hufen in den Stall. Im Hühnerfutter ist regelmäßig Sand enthalten.However, scissors-like cutting devices have the fundamental disadvantage that the knives have to be positioned very precisely against one another and accordingly the propeller bearings must not have any play. In addition, such knives that run past each other at a very short distance dull extremely quickly. This is not only due to foreign bodies that can get caught between the knives, but especially the sand that is always contained in the liquid manure. Grazing animals bring sand into the barn with their hooves. Chicken feed regularly contains sand.

Der Erfindung liegt die Aufgabe zugrunde, eine Schneidvorrichtung vorzuschlagen, die ohne Nachschleifen oder Nachstellen der Schneidorgane langfristig zuverlässig arbeitet, und zwar auch dann, wenn die Propellerlager ein bestimmtes Axialspiel haben.The invention has for its object to propose a cutting device that works reliably in the long term without regrinding or readjusting the cutting elements, even if the propeller bearings have a certain axial play.

Ausgehend von einer Schneidvorrichtung der einleitend bezeichneten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, daß die Schneidvorrichtung mindestens eine zweizinkige Gabel und mindestens einen Finger aufweist, von welchen beiden Schneidelementen eines am Lagergestell und eines an der Welle so angeordnet ist, daß beim Rühren der Finger zwischen den Gabelzinken durchläuft bzw. die Gabelzinken zu beiden Seiten des Fingers vorbei laufen.Starting from a cutting device of the type described in the introduction, this object is achieved according to the invention in that the cutting device has at least one two-pronged fork and at least one finger, of which two cutting elements one is arranged on the storage rack and one on the shaft so that when the fingers are stirred between passes through the forks or the forks run past on both sides of the finger.

Das Schneidprinzip beruht also darauf, daß sich das Fasergut über die Gabel legt und von dem schnell durchlaufenden Finger quer abgeschlagen wird. Dabei kann durchaus der Finger von beiden Gabelzinken einen gewissen Abstand haben, wie er durch das Lagerspiel und die üblichen Fertigungstoleranzen vorgegeben ist. Weder die Gabelzinken noch der Schlagfinger brauchen grundsätzlich scharf geschliffen zu sein, denn die Fasern werden nicht in ziehendem Schnitt abgetrennt, sondern eher durchgeschlagen, wobei sie zu beiden Seiten der Trennstelle von je einer Gabelzinke gegengehalten werden. Das schließt jedoch nicht aus, daß die Gabelzinken und/oder der Finger vorzugsweise als Messer ausgebildet und im wesentlichen flächenparallel angeordnet sind. Dabei kann sich bei entsprechender Schrägstellung der Messerschneiden gleichwohl ein ziehendes Schnittverhalten ausbilden.The cutting principle is based on the fact that the fiber material lies over the fork and is transversely knocked off by the quickly running finger. The finger can be at a certain distance from both fork tines, as dictated by the bearing play and the usual manufacturing tolerances. Neither the forks nor the striking fingers need to be sharply ground, because the fibers are not cut in a pulling cut, but rather cut through, with each fork being held against each side by a fork. However, this does not rule out the fact that the fork tines and / or the fingers are preferably designed as knives and are arranged essentially parallel to the surface. If the knife edges are inclined accordingly, pulling cutting behavior can nevertheless develop.

Besonders zweckmäßig ist es, handelsübliche, für Scherbalken vom Mähmaschinen bestimmte Messerklingen zu verwenden, die etwa die Grundform eines gleichschenkligen Dreiecks haben, dessen beide Schenkel angeschliffen sind. Diese Messerklingen sind sehr verbreitet und werden für Mähwerke in hohen Stückzahlen benötigt, so daß sie nicht nur preiswert, sondern auch von hervorragender Qualität sind. Außerdem haben diese Messerklingen meistens gezackte Schneiden, was für den vorliegenden Anwendungsfall vorteilhaft ist.It is particularly expedient to use commercially available knife blades which are intended for shear bars from the mowing machine and which have approximately the basic shape of an isosceles triangle, the two legs of which are ground. These knife blades are very common and are required for mowers in large quantities, so that they are not only inexpensive, but also of excellent quality. In addition, these knife blades mostly have serrated edges, which is advantageous for the present application.

Als besonders vorteilhafte Ausführungsform wird vorgeschlagen, daß zwei Messerklingen deckungsgleich in einem bestimmten Abstand voneinander in Radialebenen bezüglich der Propellerwelle an der spornartigen Stütze des Lagergestells befestigt sind und daß mit diesem Doppelmesser mehrere einzelne Messerklingen zusammenwirken. Diese Einzelklingen werden vorteilhafterweise sternförmig mit gleichen Winkelabständen an einer Scheibe befestigt, die aus DE-GM 84 33 962 bekannt und an der Saugseite des Propellers an diesem oder unmittelbar an der Welle angebracht ist.As a particularly advantageous embodiment, it is proposed that two knife blades are congruently fastened at a certain distance from one another in radial planes with respect to the propeller shaft on the spur-like support of the bearing frame and that several individual knife blades interact with this double knife. These individual blades are advantageously attached in a star shape with the same angular spacing to a disk which is known from DE-GM 84 33 962 and is attached to the propeller on the suction side thereof or directly on the shaft.

Einzelheiten eines dementsprechenden Ausführungsbeispiels der Erfindung werden nachfolgend anhand der Zeichnung erläutert. Im einzelnen zeigt

  • Fig. 1 eine Seitenansicht des propellerseitigen Endabschnitts einer durch Schlepper-Zapfwelle antreibbaren Rührvorrichtung mit Schneidvorrichtung,
  • Fig. 2 den Propeller und die Schneidvorrichtung gemäß Fig. 1 in größerem Maßstab und Fig. 3 einen Querschnitt III-III der Rühr- und Schneidvorrichtung nach Fig. 2.
Details of a corresponding embodiment of the invention are explained below with reference to the drawing. In detail shows
  • 1 is a side view of the propeller-side end section of a stirring device with cutting device which can be driven by tractor PTO shaft,
  • Fig. 2 shows the propeller and the cutting device according to FIG. 1 on a larger scale and 3 shows a cross section III-III of the stirring and cutting device according to FIG. 2.

Fig. 1 zeigt den Endabschnitt eines langgestreckten Lagerrohrs 1, dessen anderes Ende am Schlepper oder bei Elektroantrieb an einem stationären Stativ schwenkbar gehalten ist. An dem Lagerrohr ist mit Hilfe einer Klemmschelle 2 ein Sporn 3 in Gestalt eines zweimal gekröpften Rohrabschnitts angebracht. An dem Sporn ist eine Stütze 4 angeschweißt, die oben in eine T-förmige Auflage mit hochgebogenen Endlappen 5 übergeht. Das Lagerrohr 1 wird durchsetzt von einer Welle 6, deren Hartholzlager in einem Lagerkasten 7 enthalten ist, der samt seinem Deckel 8 einerseits mit der T-förmigen Auflage der Stütze 4 und andererseits mittels einer weiteren Klemmschelle 9 mit dem Lagerrohr 1 verschraubt ist.Fig. 1 shows the end portion of an elongated bearing tube 1, the other end of which is pivotally held on the tractor or in the case of an electric drive on a stationary tripod. A spur 3 in the form of a twice cranked tube section is attached to the bearing tube with the aid of a clamp 2. A support 4 is welded to the spur, which merges at the top into a T-shaped support with upturned end tabs 5. The bearing tube 1 is penetrated by a shaft 6, the hardwood bearing is contained in a bearing box 7 which, together with its cover 8, is screwed to the bearing tube 1 on the one hand with the T-shaped support of the support 4 and on the other hand by means of a further clamp 9.

In den Figuren 2 und 3 ist deutlicher dargestellt, daß auf der Welle 6 die Nabe 10 eines dreiflügeligen Propellers mit Hilfe radialer Klemmschrauben 11 festgeklemmt ist. An den saugseitigen Kanten der Propellerflügel 12 ist eine radiale Ringscheibe 13 angebracht, die ihrerseits einen kurzen Zylindermantel 14 trägt welcher die Klemmschrauben 11 abdeckt. Die Schrauben sind jedoch über entsprechende Öffnungen im Zylindermantel 14 zugänglich.In Figures 2 and 3 it is shown more clearly that the hub 10 of a three-bladed propeller is clamped on the shaft 6 by means of radial clamping screws 11. A radial annular disk 13 is attached to the suction-side edges of the propeller blades 12, which in turn carries a short cylinder jacket 14 which covers the clamping screws 11. However, the screws are accessible via corresponding openings in the cylinder jacket 14.

Die dargestellte Schneidvorrichtung besteht aus drei einzelnen rotierenden Messerklingen 15 (Finger) und einer feststehenden Doppelklinge 16 (Gabel). Die Einzelklingen 15 sind in Winkelabständen von 120° an der Rückseite der Ringscheibe 13 mit Schrauben 17 angeschraubt, so daß der Klingenabschnitt mit den beiden aufeinander zulaufenden Schneiden radial über die Ringscheibe 13 hinaus vorsteht. Um ein Verdrehen um die einzige Befestigungsschraube 17 zu vermeiden sind jeweils noch kleinere Stützschrauben 18 in die Ringscheibe eingebracht, an denen sich die Basiskanten der Messerklingen 15 anlegen.The cutting device shown consists of three individual rotating knife blades 15 (fingers) and a fixed double blade 16 (fork). The individual blades 15 are screwed at an angle of 120 ° to the back of the ring disk 13 with screws 17, so that the blade section with the two converging blades protrudes radially beyond the ring disk 13. To twist around the only fastening screw 17 to avoid, smaller support screws 18 are introduced into the ring washer, against which the base edges of the knife blades 15 rest.

Die Doppelklinge 16 besteht aus zwei weiteren Messerklingen 15, zwischen die ein Distanzstück 19 eingefügt ist. Sie sind mit diesem Distanzstück an eine an der Stütze 4 befestigte Konsole 20 angeschraubt, wobei die Basiskanten der Messerklingen 15 sich auf eine Leiste 21 der Konsole auflegen. Dadurch ist die Doppelklinge 16 drehfest gehalten. Auch ihre Klingen sind flächenparallel zu einer Radialfläche ausgerichtet. Die Schneiden weisen zur Welle 1 hin und der Abstand von der Welle ist so gewählt, daß die rotierenden Messerklingen 15 sich zwischen den Einzelklingen der Doppelklinge 16 hindurch bewegen.The double blade 16 consists of two further knife blades 15, between which a spacer 19 is inserted. With this spacer, they are screwed to a bracket 20 fastened to the support 4, the base edges of the knife blades 15 resting on a bar 21 of the bracket. As a result, the double blade 16 is held in a rotationally fixed manner. Their blades are also aligned parallel to a radial surface. The cutting edges point towards the shaft 1 and the distance from the shaft is chosen so that the rotating knife blades 15 move between the individual blades of the double blade 16.

Der axiale Abstand zwischen den Einzelklingen der Doppelklinge 16 entspricht dem zu erwartenden Lagerspiel. Ein Nachstellen der Klingen ist daher nicht erforderlich. Ebensowenig ein Nachschleifen, da das im Flüssigmist enthaltene Langgut auch dann noch mit hinreichender Wirksamkeit zerstückelt wird, wenn die Klingen durch sehr langen Gebrauch abgestumpft sein sollten.The axial distance between the individual blades of the double blade 16 corresponds to the bearing play to be expected. It is therefore not necessary to readjust the blades. Nor is regrinding necessary, since the long material contained in the liquid manure is broken up with sufficient effectiveness even if the blades have become blunted due to very long use.
