Nachteil des bekannten Standes der Technik ist die relativ komplizierte konstruktive Ausführung dieser Lösungen. Bei Einsatz auf einer Baustelle ist davon auszugehen, dass einfache und wartungsarme Konstruktionen zum Einsatz kommen, um eine unkomplizierte Verwendung dieser Vorrichtungen gewährleisten zu können.Disadvantage of the known prior art is the relatively complicated structural design of these solutions. When used on a construction site, it can be assumed that simple and low-maintenance constructions are used to ensure uncomplicated use of these devices.

Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung gemäß den Schutzansprüchen 1 bis 9 gelöst.According to the invention this object is achieved by a device according to the claims 1 to 9.

Nachfolgend soll diese Vorrichtung anhand der Abbildungen 1 bis 3 und einem Ausführungsbeispiel näher erläutert werden.Below, this device will be explained in more detail with reference to Figures 1 to 3 and an embodiment.

Die Abbildung 1 zeigt dabei die erfindungsgemäße Vorrichtung in einer Gesamtansicht mit Mischkübel 10, Abbildung 2 zeigt eine Seitenansicht der erfindungsgemäßen Vorrichtung ohne Mischkübel 10 und Abbildung 3 zeigt den offenen Mischkübel 10 auf einem Transportwagen 4 aufstehend.The illustration 1 shows the device according to the invention in an overall view with mixing bucket 10, Figure 2 shows a side view of the device according to the invention without mixing bucket 10 and Figure 3 shows the open mixing bucket 10 on a trolley 4 standing up.

Die erfindungsgemäße Vorrichtung soll anhand der Abbildungen 1 bis 3 und in der Ausführung einer Mischstation für Mörtel näher erläutert werden.The device according to the invention will be explained in more detail with reference to Figures 1 to 3 and in the execution of a mixing station for mortar.

Die erfindungsgemäße Mischstation besteht aus einem Grundgestell, welches so ausgeführt ist, dass es den sicheren Stand der Vorrichtung gewährleistet, mit darauf angeordneter vertikaler Führungssäule 1 und darauf vertikal verschiebbarem Führungsschlitten 7.The mixing station according to the invention consists of a base frame, which is designed so that it ensures the secure state of the device, with arranged thereon vertical guide column 1 and thereon vertically displaceable guide carriage. 7

An diesem Führungsschlitten 7 angeordnet ist der Antriebsmotor 5 mit einer einen Mörtelkübel 10 nach oben in Gesamtheit seiner Öffnung abdeckenden Staubschutzhaube 2 mit mindestens einem Absauganschluss 12 und mindestens einem Einfüllschacht 3.Arranged on this guide carriage 7 is the drive motor 5 with a mortar bucket 10 upwardly in the entirety of its opening covering the dust cover 2 with at least one suction port 12 and at least one feed chute third

An diesem erfindungsgemäß angeordnetem Absauganschluss 12 können übliche und dem Stand der Technik entsprechende Absaugeinrichtungen angeschlossen.At this suction connection 12 arranged according to the invention, customary and state-of-the-art suction devices can be connected.

Der Antriebsmotor 5 treibt die das Mischgut um die Antriebsachse des Antriebsmotors 5 rotierend bearbeitenden Werkzeuge, in dieser Ausführung vorzugsweise zwei Quirle, einen inneren Quirl 8 und einen äußeren Quirl 9, an.The drive motor 5 drives the mixing material about the drive axis of the drive motor 5 rotating tools, in this embodiment preferably two Quirle, an inner whorl 8 and an outer whisk 9, to.

Ein auf einem Wagen 4 aufstehender Mörtelkübel 10 ist so angeordnet, dass die Quirle 8 und 9 bei abgesenktem Führungsschlitten 7 in den zu mischenden Mörtel eingreifen und diesen durch Rotation bearbeiten können.A standing on a carriage 4 mortar bucket 10 is arranged so that the Quirle 8 and 9 engage with lowered guide carriage 7 in the mortar to be mixed and edit it by rotation.

Der an der Oberseite der Staubschutzhaube 2 angeordnete Absauganschluss 12 als auch der Einfüllschacht 3 können in einer besonderen Ausführung der erfindungsgemäßen Lösung mit einer zusätzlichen Bürstenabdichtung ausgestattet sein.The arranged on the top of the dust cover 2 suction port 12 and the hopper 3 may be equipped in a particular embodiment of the solution according to the invention with an additional brush seal.

Ein Sicherheitsschalter überwacht die Lage die Lage des Mörtelkübels 10 zu den rotierenden Quirlen 8 und 9 und der Staubschutzhaube 2.A safety switch monitors the position of the position of the mortar bucket 10 to the rotating whorls 8 and 9 and the dust cover. 2

Vorzugweise ist zum Anheben des Führungsschlittens 7 auf der Führungssäule 1 eine diese Hubbewegung unterstützende Gasdruckfeder 12 angeordnet. Dieses Hilfsmittel ist im Sinne der Erfindung nicht ausschließlich eine Gasdruckfeder, sondern es ist der Einsatz jedweden gleichwirkenden Hilfsmittels umfasst.Preferably, for lifting the guide carriage 7 on the guide column 1, a lifting movement supporting this gas spring 12 is arranged. This aid is for the purposes of the invention not exclusively a gas spring, but it is the use of any equivalent means.

Auch als eine besondere Ausführungsform der erfindungsgemäßen Lösung ist zu betrachten, dass der Mörtelkübel 10 auf dem Wagen 4 mittels einer in üblicher technischer Weise ausgeführten Verriegelung 11 sicher arretiert wird. Das Grundgestell der erfindungsgemäßem Vorrichtung ist vorzugsweise so gestaltet, dass der Wagen 4 zum Transport des Mörtelkübels 10 bei Anordnung in Arbeitslage, also abgedeckt durch die der Staubschutzhaube 2 mit seien Rädern auf dem Grundgestell 1 zu stehen kommt und somit bei Veränderung des Einsatzortes die gesamte Vorrichtung in einem Arbeitsgang transportiert werden kann.It should also be considered as a particular embodiment of the solution according to the invention that the mortar bucket 10 is securely locked on the carriage 4 by means of a lock 11 made in the usual technical manner. The base frame of the device according to the invention is preferably designed so that the carriage 4 comes to transport the mortar bucket 10 when placed in working position, so covered by the dust cover 2 with wheels on the base frame 1 and thus the entire device when changing the location can be transported in one operation.

Vorzugsweise ist deshalb das Grundgestell 1 mit Rädern 6 ausgestattet, auf welchen die Vorrichtung bei Ankippen alleinig aufsteht und somit auf diesen Rädern 6 gerollt werden kann.Preferably, therefore, the base frame 1 is equipped with wheels 6, on which the device stands alone when tilting and thus can be rolled on these wheels 6.

Nachfolgend soll die Funktionsweise der erfindungsgemäßen Vorrichtung erläutert werden.Below, the operation of the device according to the invention will be explained.

Als Erstes wird in dem Mörtelkübel 10 die nötige Menge Wasser eingefüllt. Danach wird der Wagen 4 mit Mörtelkübel in die Station geschoben und die Antriebseinheit 7 mit den Quirlen 8 und 9 in den Mörtelkübel 10 abgesenkt, bis diese einrastet.First, in the mortar bucket 10, the necessary amount of water is filled. Thereafter, the carriage 4 is pushed with mortar bucket in the station and the drive unit 7 is lowered with the whorls 8 and 9 in the mortar bucket 10 until it engages.

Im Anschluss wird der geöffnete Mörtelsack bei laufender Maschine in den Einfüllschacht 3 eingefüllt.Subsequently, the open mortar bag is filled while the machine is running in the hopper 3.

Bürstenabdichtungen im Einfüllschacht 3 und im Absauganschluss 12 an der Staubschutzhaube 2 bewirken ein staubarmes Anmischen.Brush seals in the filling shaft 3 and the suction port 12 on the dust cover 2 cause a low-dust mixing.

Für das Anmischen kann über einen Schalter die Drehzahl des Motors halbiert und so die Staubentwicklung noch weiter reduziert werden.For mixing, the speed of the motor can be halved via a switch, which further reduces dust formation.

Für ein gutes Mischergebnis sorgen zwei gegenläufige Quirle 8 und 9. Der innere Quirl 8 ist vorzugsweise schnelllaufend für eine hohe Durchwirbelung des Mischguts. Der äußere Quirl 9 ist vorzugsweise langsamlaufend und für die Mitnahme und Beförderung des Mischguts von der Mörtelkübelwand zum inneren Quirl zuständig.For a good mixing result provide two opposing Quirle 8 and 9. The inner whisk 8 is preferably fast-running for a high turbulence of the mix. The outer whirl 9 is preferably slow running and responsible for the entrainment and transport of the mix from the mortar bucket wall to the inner whisk.

Hierdurch wird eine hohe Mischgutbewegung und Durchmischung sichergestellt.As a result, a high Mischgutbewegung and mixing is ensured.

Wenn die Antriebseinheit 7 bei laufender Maschine aus dem Mörtelkübel 10 gehoben wird, verhindert ein Sicherheitsschalter ein Weiterlaufen der Quirle 8 und 9 und schaltet den Antrieb ab.When the drive unit 7 is lifted while the machine is running out of the mortar bucket 10, a safety switch prevents the quirks 8 and 9 from running on and switches off the drive.

Durch Verwendung dieses Sicherheitsschalters kann ein erneutes Anlaufen der Maschine nur mit aufgelegter Staubschutzhaube 2 und somit eingetauchten Quirlen 8 und 9 erfolgen.By using this safety switch a restart of the machine can only be done with the dust cover 2 and thus immersed whorls 8 and 9.

Wenn das Mischgut fertigt ist, kann der Antrieb aus dem Mischgut gehoben werden, hierbei hilft eine Gasdruckfeder 12, die den Kraftaufwand beim Heben der Antriebseinheit 7 deutlich reduziert.When the mix is finished, the drive can be lifted from the mix, this helps a gas spring 12, which significantly reduces the effort required to lift the drive unit 7.

Nun können anhaftende Mischgutrückstände von den Quirlen 8 und 9 entfernt werden.Now adhering mixed material residues can be removed from the whorls 8 and 9.

Für den einfachen Transport des Mischguts kann der Wagen 4 aus der Vorrichtung herausgezogen werden. Beim Auskippen des Mischguts hält eine Verriegelung 11 den Mörtelkübel sicher auf dem Wagen 4.For easy transport of the mix, the carriage 4 can be pulled out of the device. When dumping the mix holds a lock 11 the mortar bucket safely on the car. 4
