Description

Mezclador para hormigón y mezclas similares provisto con árboles de mezclado con doble motorización.Mixer for concrete and similar mixtures provided with mixing trees with double motorization.

La presente solicitud de patente se refiere a un mezclador para hormigón y mezclas similares, provisto con dos árboles de mezclado con ejes horizontales asistido por doble motorización.The present patent application refers to a mixer for concrete and similar mixtures, provided with two mixing shafts with double-assisted horizontal shafts motorization.

Como es sabido, los mezcladores para hormigón o mezcladores similares comprenden normalmente un depósito grande con dos árboles contrarrotativos con ejes horizontales, en los que están montadas series de brazos axiales usados para mezclar el compuesto contenido en el depósito; véase, por ejemplo, el documento DE - C - 939 200.As is known, concrete mixers or Similar mixers typically comprise a large tank with two counter-rotating trees with horizontal axes, in which they are mounted series of axial arms used to mix the compound content in the deposit; see, for example, document DE-C - 939 200.

De acuerdo con la tecnología actual, cada árbol se monta y se apoya en dos paredes opuestas del depósito, contemplándose también que en el exterior del depósito un extremo de cada árbol esté acoplado con un motor reductor que puede hacer girar el árbol, mientras que el otro extremo del árbol está apoyado en un cojinete adecuado fijo a la pared del depósito.According to current technology, each tree Mounts and rests on two opposite walls of the tank, also contemplating that on the outside of the tank an end of each shaft is coupled with a reduction motor that can rotate the tree, while the other end of the tree is supported by a suitable bearing fixed to the tank wall.

A la vista de la escasa fluidez de los compuestos a mezclar, cada árbol de mezclado está asistido por un motor reductor potente.In view of the low fluidity of the compounds to mix, each mixing shaft is assisted by an engine powerful reducer

Esta exigencia en particular ha impedido hasta ahora la construcción de grandes mezcladores, ya que el mezclado de grandes volúmenes de compuesto requiere la adopción de motores reductores con mayores dimensiones y más potencia en comparación con los modelos producidos actualmente por los fabricantes.This particular requirement has prevented even now the construction of large mixers, since the mixing of large volumes of compound requires the adoption of engines reducers with larger dimensions and more power compared to the models currently produced by the manufacturers.

Por esta razón, los usuarios que necesitan mezcladores más grandes se han visto obligados hasta ahora a solicitar a los fabricantes el diseño y producción de motores reductores "especiales" de muy alta potencia, que implican grandes dificultades y gastos.For this reason, the users who need larger mixers have been forced so far to request manufacturers to design and produce engines "special" reducers of very high power, which involve great difficulties and expenses.

La finalidad de la presente invención es realizar mezcladores con depósitos de mezclado muy grandes en comparación con los mezcladores ordinarios, evitando de esta manera la necesidad de fabricar los costosos motores reductores "especiales" con las grandes dimensiones antes mencionadas.The purpose of the present invention is to realize mixers with very large mixing tanks compared to ordinary mixers, thus avoiding the need for manufacture the expensive "special" reduction motors with the large dimensions mentioned above.

De acuerdo con la presente invención, se instala un par de motores reductores estándar en cada árbol de mezclado. Con más precisión, cada motor reductor se debe aplicar a cada extremo correspondiente del árbol de mezclado externamente en la pared del depósito.In accordance with the present invention, it is installed a pair of standard reduction motors in each mixing shaft. With more precision, each reducing motor must be applied to each end corresponding of the mixing tree externally on the wall of the Deposit.

Parece evidente que este tipo de árbol de mezclado puede estar provisto con alta potencia -que es la potencia de los dos motores reductores- sin necesidad de piezas especiales o de modificar la estructura general del mezclador.It seems obvious that this type of tree mixed can be provided with high power - which is the power of the two reducing motors - no need for special parts or to modify the overall structure of the mixer.

Para mayor claridad se continúa la descripción de la invención haciendo referencia a los dibujos adjuntos, que se incluyen a fines de ilustración y no en sentido limitativo, en los que las figuras 1, 2 y 3 son una vista lateral, una vista frontal y una vista desde arriba, respectivamente, del mezclador de acuerdo con la presente invención.For clarity the description of the invention referring to the attached drawings, which are include for purposes of illustration and not in a limiting sense, in the that figures 1, 2 and 3 are a side view, a front view and a top view, respectively, of the mixer according with the present invention.

Haciendo referencia a las figuras adjuntas, el mezclador (1) de acuerdo con la presente invención comprende un depósito (2) de mezclado rectangular provisto con una tapa (3) con aberturas (3a) laterales. Los extremos de los dos árboles de mezclado paralelos contrarrotativos con eje horizontal están instalados en las paredes (4) transversales del depósito
(2).Referring to the attached figures, the mixer (1) according to the present invention comprises a rectangular mixing tank (2) provided with a lid (3) with lateral openings (3a). The ends of the two counter-rotating parallel mixing shafts with horizontal axis are installed in the transverse walls (4) of the tank
(two).

Como se mencionó anteriormente, la principal característica de la invención la representa el hecho de que tiene cuatro motores reductores, por lo cual cada extremo de cada árbol está acoplado con uno de los correspondientes motores reductores (5) de dimensiones y potencia estándar situados externamente en las correspondientes paredes (4) transversales del depósito (2).As mentioned earlier, the main characteristic of the invention is represented by the fact that it has four reducing motors, so each end of each tree is coupled with one of the corresponding reduction motors (5) of standard dimensions and power located externally in the corresponding transverse walls (4) of the tank (2).
