Abstract
LA INVENCION SE REFIERE A UNA HERRAMIENTA DE EXCAVACION EN LA QUE SE SUMINISTRA UN DISPOSITIVO QUE RECIBE LA FUERZA DE GOLPEO DE UN MARTILLO Y LA FUERZA ROTACIONAL DE UN CILINDRO DE MARTILLO, Y EN UNA SUPERFICIE DE FONDO DE ESTE, SE PROVEEN AL MENOS TRES AGUJEROS DE EJES (2A; 2B; 2C) DESPLAZADOS DEL CENTRO DEL DISPOSITIVO (2) Y EN INTERVALOS ANGULARES EQUIVALENTES EN DIRECCION CIRCUNFERENCIAL. SE INSERTAN UNOS EJES EN BLOQUE (3A; 3B; 3C) EN LOS AGUJEROS DE EJE (2A; 2B; 2C) EN UNA FORMA DE ROTACION LIBRE, Y HAY UNOS BLOQUES (11A; 11B; 11C) QUE TIENEN UNA FORMA DE ABANICO RUDO Y TIENEN BROCAS EMPOTRADAS EN SUS SUPERFICIES DE AVANCE EXTREMAS, PROVISTOS EN PARTES EXTREMAS DE AVANCE DE LOS EJES DE BLOQUE (3A; 3B; 3C) DE TAL FORMA QUE LAS CARAS LATERALES IZQUIERDAS Y DERECHAS (12A; 12B) DE DICHOS BLOQUES (11A; 11B; 11C) ESTAN EN OPOSICION MUTUA Y PARTES DE ARCO (12C) DE TODOS LOS BLOQUES (11A; 11B; 11C) JUNTOS, FORMAN TOSCAMENTE UNA FORMA DE CIRCULO. CUANDO DICHO DISPOSITIVO ES GIRADO EN LA DIRECCION DE EXCAVACION, DICHOS BLOQUES (11A; 11B; 11C) GIRAN COMO RESULTADO DE LA RESISTENCIA A LA EXCAVACION DE LA PARTE DE FONDO DEL AGUJERO DE EXCAVACION, UNA PARTE DE INSERCION DE LAS CARAS LATERALES (12A; 12B) Y LA PARTE DE ARCO (12C) DE CADA BLOQUE (11A; 11B; 11C) SOBRESALE MAS ALLA DE LA SUPERFICIE CIRCUNFERENCIAL EXTERNA DEL DISPOSITIVO POR UNA CANTIDAD DE EXCAVACION PREDETERMINADA, Y LAS POSICIONES MUTUAS DE LOS EJES DE BLOQUE (3A; 3B; 3C) CON RESPECTO A LOS BLOQUES (11A; 11B; 11C) ESTAN DETERMINADAS DE TAL FORMA QUE AMBAS CARAS LATERALES (12A; 12B) DE CADA BLOQUE (11A; 11B; 11C) ENTRAN EN CONTACTO CON LAS CARAS LATERALES (12A; 12B) DE BLOQUES VECINOS (11A; 11B; 11C) EN ESTE MOMENTO.
