Abstract

The present invention relates to a mixer for concrete and similar mixtures, of the type provided with a rectangular mixing tank (2), on whose lateral walls (4) the ends of two counter-rotating parallel mixing shafts with horizontal axis are fitted, it being provided that each end of each shaft is coupled with a geared motor (5) of standard size and power located externally on the bearing wall (4) of the tank (2). <IMAGE>

Description

Die vorliegende Patentanmeldung betrifft eine Mischmaschine für Beton und ähnliche Gemische, die mit zwei Mischerwellen mit horizontaler Achse ausgestattet sind, die durch eine doppelte Motorisierung unterstützt werden.The The present patent application relates to a mixer for concrete and similar Mixtures equipped with two mixer shafts with a horizontal axis are supported by a double motorization.

Bekanntermaßen weisen Mischmaschinen für Beton und ähnliche Gemische zur Zeit einen großen Trog mit zwei gegensinnig rotierenden Wellen mit horizontaler Achse auf, an denen eine Reihe radialer Arme angebracht sind, die verwendet werden, um die in dem Trog enthaltenen Substanzen zu vermischen, siehe zum Beispiel Dokument DE-C-939 200.Known to show Mixing machines for Concrete and the like Mix a big one right now Trough with two counter-rotating shafts with a horizontal axis on which a number of radial arms are attached that are used in order to mix the substances contained in the trough, see for example document DE-C-939 200.

Nach der gegenwärtigen Technik ist jede Welle an zwei einander gegenüberliegenden Wänden des Trogs befestigt und wird von diesen gehalten, wobei es ebenfalls vorgesehen ist, daß auf der Außenseite des Trogs ein Ende jeder Welle mit dem Getriebemotor gekoppelt ist, der geeignet ist die Welle zu drehen, während das andere Ende der Welle mit Hilfe eines geeigneten Lagers gehaltert ist, das an der Wand des Trogs befestigt ist.To the current Technology is each wave on two opposite walls of the Trogs attached and is held by these, as well it is intended that on the outside one end of each shaft of the trough is coupled to the gear motor, which is capable of rotating the shaft while the other end of the shaft with the help of a suitable bearing that is held on the wall the trough is attached.

In Hinblick auf die schlechte Fließfähigkeit der zu mischenden Substanzen, wird jede Mischerwelle durch einen sehr starken Getriebemotor unterstützt.In In view of the poor fluidity of the substances to be mixed, each mixer shaft is characterized by a very strong gear motor supported.

Dieses spezielle Erfordernis hat bisher die Konstruktion von großen Mischmaschinen verhindert, da das Mischen großer Substanzvolumina die Anwendung von Getriebemotoren größerer Dimensionen und mit mehr Kraft im Vergleich zu den Modellen, die gegenwärtig durch die Hersteller erzeugt werden, erfordert.This So far, the design of large mixing machines has had special requirements prevented because the mixing great Substance volumes the use of geared motors of larger dimensions and with more power compared to the models currently available through the manufacturers are producing requires.

Aus diesem Grund waren Nutzer, die größere Mischmaschinen benötigten, gezwungen, Hersteller zu bitten, "spezielle" Getriebemotoren mit sehr hoher Leistung zu entwickeln und herzustellen, was große Schwierigkeiten und Ausgaben beinhaltet.Out for this reason, users who needed larger mixers forced to ask manufacturers to "special" gear motors with very high performance to develop and manufacture what great difficulties and expenses includes.

Die Aufgabe der vorliegenden Erfindung besteht darin, Mischmaschinen mit sehr großen Mischtanks im Vergleich zu herkömmlichen Mischmaschinen zu verwirklichen, und so die Notwendigkeit zu vermeiden, die teuren "speziellen" Getriebemotoren mit großen Leistungen, wie sie oben erwähnt wurden, herstellen zu müssen.The The object of the present invention is mixing machines with very large mixing tanks compared to conventional ones Realizing mixing machines, thus avoiding the need the expensive "special" geared motors with big Services as mentioned above have to manufacture.

Erfindungsgemäß werden zwei Standard-Getriebemotoren an jede Mischerwelle der Mischmaschine angeschlossen. Genauer gesagt, muß jeweils ein Getriebemotor außerhalb der Trogwand an jeweils dem entsprechenden Ende der Mischerwelle angebracht werden.According to the invention two standard geared motors on each mixer shaft of the mixer connected. More specifically, a geared motor must be used outside the trough wall at the respective end of the mixer shaft be attached.

Es erscheint offensichtlich, daß einer derartigen Mischerwelle hohe Energie zugeführt werden kann, das heißt die Kraft der beiden Getriebemotoren – ohne daß spezielle Teile erforderlich sind oder der Grundaufbau der Mischmaschine verändert werden muß.It it seems obvious that one such mixer shaft high energy can be supplied, that is, the force of the two geared motors - without that special Parts are required or the basic structure of the mixer must be changed.

Zur Klarstellung wird die Beschreibung der Erfindung im folgenden in Bezug auf die beiliegenden Zeichnungen fortgesetzt, die Zwecken der Illustration dienen und nicht in begrenzendem Sinne zu verstehen sind, wobei die 1, 2 und 3 jeweils eine Seitenansicht, eine Frontansicht und eine Ansicht der erfindungsgemäßen Mischmaschine von oben sind.For clarification, the description of the invention is continued below with reference to the accompanying drawings, which are for the purpose of illustration and are not to be understood in a limiting sense, the 1 . 2 and 3 are a side view, a front view and a view of the mixer according to the invention from above.

Nach den beiliegenden Zeichnungen weist die erfindungsgemäße Mischmaschine (1) einen rechteckigen Mischtank (2) mit einer Abdeckung (3) mit seitlichen Öffnungen (3a) auf. Die Enden der beiden gegensinnig rotierenden parallelen Mischerwellen mit horizontalen Achsen sind an den Querwänden (4) des Trogs (2) befestigt.According to the accompanying drawings, the mixing machine according to the invention ( 1 ) a rectangular mixing tank ( 2 ) with a cover ( 3 ) with side openings ( 3a ) on. The ends of the two counter-rotating parallel mixer shafts with horizontal axes are on the transverse walls ( 4 ) of the trough ( 2 ) attached.

Wie zuvor erwähnt, wird das Hauptmerkmal der Erfindung durch die Tatsache wiedergegeben, daß sie vier Getriebemotoren aufweist, wobei jeweils ein Ende jeder Welle mit einem der entsprechenden Getriebemotoren (5) mit Standardabmessungen und Standardleistung gekoppelt sind, welche außerhalb an den entsprechenden Querwänden (4) des Trogs (2) angebracht sind.As previously mentioned, the main feature of the invention is represented by the fact that it has four geared motors, one end of each shaft having one of the corresponding geared motors ( 5 ) are coupled with standard dimensions and standard power, which are located outside on the corresponding transverse walls ( 4 ) of the trough ( 2 ) are attached.
