Abstract

MAQUINA ROZADORA PARA EXPLOTACIONES MINERAS, CONSTITUIDA POR VARIOS MODULOS SUSTITUIBLES. EL CENTRAL ES UN MOTOR ELECTRICO (9), CUYO EJE SE PROLONGA POR SUS DOS EXTREMOS EN LOS QUE SE ACOPLAN SENDOS REDUCTORES (18), A LOS QUE SE ARTICULAN UNOS BRAZOS SOPORTES (19) BASCULANTES, PORTADOR CADA UNO DE UN TAMBOR ROZADOR (21). LOS TAMBORES (21) SON ORIENTABLES EFECTUANDO EL PRIMERO LA APERTURA DEL HUECO Y EL SEGUNDO LA ROTURA DE LA CAPA; LOS TAMBORES INCLUYEN UNA PLURALIDAD DE PICAS (25) CON CABEZA DE VIDIA. LA MAQUINA ESTA DOTADA DE UN CIRCUITO DE LUBRICACION, OTRO DE MANDO PARA ACCIONAR LOS SOPORTES BASCULANTES Y UNO DE AGUA PARA REFRIGERACION DEL MOTOR Y ROCIADO DEL FRENTE PARA EVITAR POLVO. LA MAQUINA TRABAJA EN CAPAS MUY INCLINADAS, Y CAMBIA EL SENTIDO DE GIRO DE LOS TAMBORES POR SIMPLE SUSTITUCION DE UN PIÑON EN EL REDUCTOR.
