Abstract

MEJORAS EN MAQUINAS ROZADORAS PARA EXPLOTACIONES MINERAS. LA MAQUINA COMPRENDE DOS TAMBORES ROZADORES DISPUESTOS EN LOS DOS EXTREMOS DE LA ESTRUCTURA GENERAL, SIENDO TALES TAMBORES ACCIONADOS SIMULTANEAMENTE POR MEDIO DE UN MOTOR CENTRAL CON SU EJE DOTA DO DE DOS EXTREMOS DE SALIDA QUE, A TROVES DE RESPECTIVOS REDUCTORES Y BRAZOS DE SOPORTE, SE DOTA DE MOVIMIENTO A AQUELLOS TAMBORES, LOS CUALES ESTAN DOTADOS DE PICAS DE ARRANQUE. LA MAQUINA RESULTA APTA PARA TRABAJAR EN CAPAS DE CARBON CON INCLINACIONES ENTRE 40° Y 90°, Y POTENCIAS MINIMAS DE CAPA ENTRE 600 Y 650 MM. LA MAQUINA INCLUYE UN EQUIPO DE REFRIGERACION DEL MOTOR Y DE ELIMINACION DE POLVO, ASI COMO UN SISTEMA HIDRAULICO DE ACCIONAMIENTO DE UNOS CILINDROS MEDIANTE LOS QUE SE CONSIGUE UNA DISPOSICION FLOTANTE DE LOS BRAZOS SOPORTE DE LOS TAMBORES ROZADORES. EL CONJUNTO ES MODULAR Y FACILMENTE REVERSIBLE, ESTANDO INDICADO PARA REALIZAR TRABAJOS DE ARRANQUE DE CARBON EN LAS MINAS.IMPROVEMENTS IN SCRAPERING MACHINES FOR MINING OPERATIONS. THE MACHINE INCLUDES TWO STICKING DRUMS ARRANGED AT THE TWO ENDS OF THE GENERAL STRUCTURE, SUCH DRUMS BEING SIMULTANEOUSLY DRIVEN BY A CENTRAL MOTOR WITH ITS DOUBLE-ENDED END, WHICH, THROUGH RESPECTIVE REDUCERS, AND SOCKETS. GIVES MOVEMENT TO THOSE DRUMS, WHICH ARE EQUIPPED WITH STARTING PICKS. THE MACHINE IS SUITABLE FOR WORKING IN COAL LAYERS WITH INCLINATIONS BETWEEN 40 ° AND 90 °, AND MINIMUM LAYER POWERS BETWEEN 600 AND 650 MM. THE MACHINE INCLUDES A MOTOR COOLING AND DUST ELIMINATION EQUIPMENT, AS WELL AS A HYDRAULIC SYSTEM FOR DRIVING SOME CYLINDERS THROUGH WHICH A FLOATING ARRANGEMENT OF THE ARMS IS SUPPORTED. THE ASSEMBLY IS MODULAR AND EASILY REVERSIBLE, BEING SUITABLE FOR CARBON STARTING WORKS IN THE MINES.
