Abstract

MEJORAS INTRODUCIDAS EN MAQUINAS SOPLADORAS DE MACHOS. CONSISTEN EN ESTABLECER ENTRE EL CABEZAL DE SOPLADO (1) Y LA PLACA DE SOPLADO (3), UNA PLACA INTERMEDIA (2) DOTADA DE ORIFICIOS (4) QUE, PERMITIENDO EL LIBRE PASO DE LA ARENA CON SU AGLOMERANTE HACIA LA BOQUILLA DE SOPLADO (3) CUANDO ACTUA EL CABEZAL (1) Y SE PRODUCE EL SOPLADO, IMPIDE NO OBSTANTE EL PASO DE LA ARENA A TRAVES DE LA MISMA POR SIMPLE GRAVEDAD, CONCRETAMENTE DURANTE LA MANIOBRA DE CAMBIO O SUSTITUCION DE LA PLACA DE SOPLADO (3). LA PLACA INTERMEDIA (2) CUENTA CON AMARRES HIDRAULICOS (5) INDEPENDIENTES DE LOS AMARRES HIDRAULICOS (6) PARA LA PLACA DE SOPLADO (3), DE MANERA QUE DURANTE LA MANIOBRA DE SUSTITUCION DE ESTA ULTIMA LA PLACA INTERMEDIA (2) SE MANTIENE PERFECTAMENTE FIJADA AL CABEZAL DE SOPLADO (1). SE CONSIGUE DE ESTA MANERA UN CAMBIO DE PLACA MUCHO MAS RAPIDO, UN ENSUCIAMIENTO MINIMO DE DICHA PLACA Y UNA ELIMINACION DE LA CLASICA PERDIDA DE ARENA DURANTE EL CAMBIO.
