Description

Von Hand geführte Wasserrechenharke. Es ist oftmals versucht worden, für das Reinigender Rechen in Wassergerinnen .maschinelle Vorrichtungen in Anwendung zu bringen, aber dennoch ist man immer wieder zu der, seit altersher bekannten Rechenharke zurückgekehrt, die von Menschenhand betätigt wird, so schwer es auch, ist, Arbeiter für die anstrengende und auch gefahrvolle Bedienung der Rechenharke heranzubilden.Hand-operated water rake. It has been tried many times for cleaning rakes in water channels. machine devices in use to bring, but still one is always back to the rake that has been known since time immemorial hard as it is, workers to train them for the strenuous and dangerous operation of the rake.

Der Gegenstand der Erfindung bezieht sich ebenfalls auf eine von. Hand zu bedienende Rechenharke, wobei aber dem Wärter der größte Teil der Kraftanstrengung erspart wird, indem das Gewicht der Rechenharke durch ein Gegengewicht ausgeglichen und der oder die Stiele -der Rechenharke gelagert und geführt sind. .The subject matter of the invention also relates to one of. Hand-operated rake, but the keeper had to do most of the effort is saved by balancing the weight of the rake with a counterweight and the handle or handles of the rake are stored and guided. .

In den Fig. z und 2 der Zeichnung ist die neue Rechenharke dargestellt, und zwar in Fig. r in der Ebene parallel zur Stromrichtung -des Gerinnen und in Fig.2 in. einer Ebene senkrecht dazu.In Figs. Z and 2 of the drawing, the new rake is shown, namely in Fig. r in the plane parallel to the direction of flow -the coagulation and in Fig.2 in a plane perpendicular to it.

Die Rechenharke besteht aus einer Winkelplatte, an; ideren einem Schenkel, d, die Reinigungszähne c und an deren anderem Schenkel, a, zwei Stiele b befestigt sind:, die an ihren oberen Emden, durch eine Querstange c verbunden und durch Kreuzstreben f gegen Verschiebungen gesichert sind. An der Querverbindung e greifen zwei Seile i an, die über Rollen k führen und an ihrem Ende mit einem Gegengewicht 1 mit Handhaben versehen sind, welches das Gewicht der Rechenharke ganz oder zum Teil ausgleicht.The rake consists of an angle plate, on; ideren one leg, d, the cleaning teeth c and on the other leg, a, two stems b are attached: which are connected to their upper emden by a cross bar c and secured against displacement by cross braces f. Two ropes i, which lead over pulleys k and are provided at their end with a counterweight 1 with handles, which completely or partially compensates for the weight of the rake, attack the cross connection e.

In einer Höhe von etwa 6o cm über dem Rechenpodest D ist ein Balken A über .die ganze Breite des Rechens d angeordnet, auf dem idie Stiele b derRechenharke in Böcken B gelagert sind.At a height of about 60 cm above the rake platform D , a bar A is arranged over the entire width of the rake d, on which the handles b of the rake are mounted in brackets B.

Bei der Bewegung der Rechenharke von der unteren in ihre obere Stellung, wo der Schenkel & der Winkelplatte mit dem Rechen-; podest D in gleicher Höhe steht, greifen die Rechenzähne c in den Rechen in bekannter Weise ein und nehmen den auf dem Rechen ;lagernden Unrat mit in die Höhe, .um ihn auf dem Rechenpodest D ablegen zu können.When moving the rake from the lower to its upper position, where the leg & the angle plate with the rake; platform D at the same height stands, the rake teeth c engage in the rake in a known manner and take the rubbish stored on the rake in the air, around it on the rake pedestal D to be able to take off.

Beider Bewegung von der oberen Stellung der Rechenharke in die untere dürfen die j Rechenzähne c nicht in den Rechen d eingreifen; :daher muß bei dieser Bewegung die Rechenharke in die gestrichelt gezeichnete Lage b1 gezogen werden, was die oben genannten Führungen .k der Böcke B zulassen.When moving from the upper position of the rake to the lower the j rake teeth c must not intervene in the rake d; : therefore must with this Movement the rake can be pulled into the dashed line position b1, what the above mentioned guides .k of the blocks B allow.

Sobald Idas Feld I (Fig. 2) des Rechens d gereinigt ist, wird die Rechenharke in das nächste Feld II verlegt, zu welchem. Zwecke die Böcke B in genügender Zahl und in gleicher Entfernung voneinander vorhanden sind; bei dieser Verlegung der Rechenharke müssen die oben genannten Rollen k mitwandern, daher sind sie an einer Laufkatze o mit Rollen m befestigt, die auf dem Balken C zu verschieben ist.As soon as Idas field I (Fig. 2) of rake d has been cleaned, the Rake moved to the next field II, to which. Purposes the blocks B in sufficient Number and are present at the same distance from each other; at this relocation the rake must follow the above roles k, so they are on a trolley o attached with rollers m, which is to be moved on the beam C.
