Abstract

LA PRESENTE INVENCION PERTENECE AL CAMPO DE LAS MAQUINAS DE BARRIDO INDUSTRIAL. PARA SER MAS PRECISOS, LA INVENCION SE REFIERE A UN DISPOSITIVO PARA EL AUTO-NIVELADO Y EL AJUSTE (7) DEL RODILLO DE ESCOBILLA (2) QUE INCLUYE ELEMENTOS ELASTICOS (11) PARA CONTROLAR Y AJUSTAR LA OSCILACION DEL RODILLO (2) SOBRE SU PROPIO EJE DE SUSPENSION Y DE OSCILACION (3) DE TAL FORMA QUE EL RODILLO DE ESCOBILLA (2) EJERZA UNA PRESION PRE-ESTABLECIDA NORMALMENTE DIFERENTE DE LA DERIVADA DE SU PROPIA FUERZA DE PESO EN LA SUPERFICIE A BARRER.THE PRESENT INVENTION BELONGS TO THE FIELD OF INDUSTRIAL SWEEPING MACHINES. TO BE MORE ACCURATE, THE INVENTION REFERS TO A DEVICE FOR SELF-LEVELING AND ADJUSTMENT (7) OF THE BRUSH ROLLER (2) THAT INCLUDES ELASTIC ELEMENTS (11) TO CONTROL AND ADJUST THE ROLLER OSCILLATION (2) ON ITS OWN SUSPENSION AND OSCILLATION AXLE (3) IN SUCH A WAY THAT THE BRUSH ROLLER (2) EXERCISES A PRE-ESTABLISHED PRESSURE NORMALLY DIFFERENT FROM THE DERIVATIVE OF ITS OWN WEIGHT FORCE ON THE SURFACE AT BARRER.
