Titel: Verbindungsgestänge für eine MörtelmischpumpeTitle: Connecting rod for a mortar mixing pump
GebrauchsmusterUtility model
Die Neuerung betrifft ein Verbindungsgestänge für eine Mörtelmischpumpe, bei dem eine einzelne Stange einerends ein Kupplungsstück zum Ankuppeln an einen Motor aufweist und anderenends mittig an einem Querteil eines Mischkorb-Rahmens befestigt ist, bei dem der Mischkorb-Rahmen zwei von dem Querteil ausgehende Rahmen-Stangen aufweist, die in der gleichen Richtung wie die einzelne Stange verlaufen und an dem dem Querteil gegenüberliegenden Ende ein Kupplungsstück zum Ankuppeln an eine Pumpe tragen, und bei dem eine von einer gebogenen Stange gebildete Wendel bei dem einen Ende an der einen Rahmen-Stange befestigt ist, mit Abstand davon der anderen Rahmen-Stange zugeordnet-am Rahmen befestigend festgelegt ist und mit dem anderen Ende in Höhe der einzelnen Stange frei ausläuft, wobei ein Wendelteil und das das Querteil umfassende Rahmenteil einen Durchgang begrenzen.The innovation relates to a connecting rod for a mortar mixing pump, in which a single rod has a coupling piece at one end for coupling to a motor and is attached centrally to a cross-section of a mixing basket frame at the other end, in which the mixing basket frame has two frame rods extending from the cross-section, which run in the same direction as the single rod and have a coupling piece at the end opposite the cross-section for coupling to a pump, and in which a spiral formed by a bent rod is attached to one frame rod at one end, is attached to the frame at a distance from the other frame rod and is attached to the frame at the other end, and runs freely at the height of the single rod, with a spiral part and the frame part comprising the cross-section delimiting a passage.
Bei einem durch die Praxis bekannten Verbindungsgestänge dieser Art endet der Rahmen mit dem Querteil mit Abstand von der befestigenden Festlegungsstelle und ist die Wendel über ein Zwischenstück gegen die andere Rahmen-Stange abgestützt. Wenn das Verbindungsgestänge in die Mörtelmischpumpe eingebaut ist, dann fließt Trockenmörtel durch den Durchgang und dringt Wasser bzw. Feuchtigkeit von dem Mischkorb in den Bereich des Durchgangs. Es bilden sich an den den Durchgang begrenzenden Stangenabschnitten Mörtelanbackungen, welche die relativ kleine Querschnittsfläche des Durchgangs verringern und das Durchströmen des Trockenmörtels verhindern.In a connecting rod of this type known from practice, the frame ends with the cross section at a distance from the fastening point and the spiral is supported against the other frame rod via an intermediate piece. If the connecting rod is installed in the mortar mixing pump, then dry mortar flows through the passage and water or moisture penetrates from the mixing basket into the area of the passage. Mortar builds up on the rod sections that limit the passage, which reduces the relatively small cross-sectional area of the passage and prevents the dry mortar from flowing through.
Eine Aufgabe der Neuerung ist es daher, ein Verbindungsgestänge der eingangs genannten Art zu schaffen, bei dem der Durchgang in der Querschnittsfläche vergrößert ist. Das neuerungsgemäße Verbindungsgestänge ist, diese Aufgabe lösend, dadurch gekennzeichnet, daß die Rahmen-Stangen sich mindestens bis zur Festlegungsstelle erstrecken, wobei die Festlegungsstelle der Wendel an der anderen Rahmen-Stange selbst ist.One of the aims of the innovation is therefore to create a connecting rod of the type mentioned at the beginning, in which the passage is enlarged in the cross-sectional area. The connecting rod according to the innovation, in order to solve this problem, is characterized in that the frame rods extend at least to the fixing point, whereby the fixing point of the helix is on the other frame rod itself.
Durch die Verlängerung des Rahmens in die Wendel hinein wird der Durchgang, der durch das Querteil begrenzt ist, größer. Das den Durchgang begrenzende Wendelteil hat sich gegenüber dem Bekannten geändert. Hierdurch sind die negativen Folgen von Mörtelanbackungen auf den Durchfluß des Trockenmörtels verringert.By extending the frame into the spiral, the passage, which is limited by the cross section, becomes larger. The spiral section that limits the passage has changed compared to the previous one. This reduces the negative effects of mortar build-up on the flow of the dry mortar.
Es ist, gegenüber dem bekannten Verbindungsgestänge, die auch Schaft genannte einzelne Stange verkürzt und der Mischkorb verlängert. Der Mischkorb ist in die Wendel hineingezogen. Die Befestigung der Wendel an dem Rahmen ist vereinfacht, weil das Zwischenstück entfallen ist. An der Position der Wendel selbst hat sich gegenüber dem Bekannten nichts geändert, da die Position der Wendel am Verbindungsgestänge durch die geforderte Anordnung der Wendel in der Mörtelmischpumpe bestimmt ist.Compared to the known connecting rod, the individual rod, also known as the shaft, is shortened and the mixing basket is longer. The mixing basket is drawn into the spiral. The fastening of the spiral to the frame is simplified because the intermediate piece has been eliminated. The position of the spiral itself has not changed compared to the known model, since the position of the spiral on the connecting rod is determined by the required arrangement of the spiral in the mortar mixing pump.
Besonders zweckmäßig und vorteilhaft ist es, wenn die Rahmen-Stangen sich mit Abstand über die Festlegungsstelle erstrecken und/oder wenn sich das Querteil des Rahmens im oberen Drittel der Höhe der Wendel befindet. Hierbei ist ein besonders langer Mischkorb gegeben, bei dem der Durchgang bzgl. des Querteils sehr vergrößert ist.It is particularly useful and advantageous if the frame rods extend at a distance above the fixing point and/or if the cross section of the frame is in the upper third of the height of the spiral. This creates a particularly long mixing basket in which the passage with respect to the cross section is greatly increased.
Eine besonders zweckmäßige und vorteilhafte Ausführungsform der Neuerung liegt vor, wenn jeweils eine der Rahmen-Stangen und ein Abschnitt des Querteils ein einheitliches gebogenes Längsteil bilden und die Enden der beiden Querteil-Abschnitte mit der einzelnen Stange verschweißt sind. Die beiden gebogenen Längsteile vereinfachen die Fertigung des Mischkorbs. Wegen des bei der Neuerung verlängerten Mischkorbs ist die Rahmen-Stange entsprechend verlängert, was ein entsprechend verlängertes Längsteil ergibt, an dem sich der Querteil-Abschnitt leicht um 90° abbiegen läßt.A particularly practical and advantageous embodiment of the innovation is when one of the frame rods and a section of the cross-section form a uniform curved longitudinal part and the ends of the two cross-section sections are welded to the individual rod. The two curved longitudinal parts simplify the manufacture of the mixing basket. Because the mixing basket is extended in the innovation, the frame rod is extended accordingly, which results in a correspondingly extended longitudinal part on which the cross-section section can easily be bent by 90°.
Besonders zweckmäßig und vorteilhaft ist es dabei, wenn die beiden Querteil-Abschnitte gegeneinander seitlich versetzt die einzelne Stange mit Längsrändern zwischen sich aufnehmen. Diese Gestaltung vereinfacht die Fertigung und ist nur brauchbar, weil der Mischkorb verlängert ist. Der seitliche Versatz des Querteil-Abschnittes neben die einzelne Stange würde bei dem bekannten kurzen Mischkorb den Durchgang ganz erheblich verengen.It is particularly practical and advantageous if the two cross-section sections are offset laterally from each other and accommodate the individual rod with longitudinal edges between them. This design simplifies production and is only usable because the mixing basket is extended. The lateral offset of the cross-section section next to the individual rod would narrow the passage considerably with the known short mixing basket.
