Abstract

UNA BROCA PARA TIERRA INCLUYE UN CONO MONTADO ROTATIVAMENTE EN UN VÁSTAGO CON UNA UNIDAD DE CUBO Y COJINETES DE RODILLOS DE<br /> EMPUJE: LA UNIDAD DE CUBO PUEDE MOVERSE ENTRE POSICIONES MONTADA Y DESMONTADA SOBRE EL VÁSTAGO COMO UNA SOLA UNIDAD, DE UNA MANERA REPETIBLE. LA UNIDAD DE CUBO INCLUYE UN PAR DE COJINETES DE RODILLOS COLOCADOS ENTRE ANILLOS DE RODADURA INTERIOR Y EXTERIOR. EL ANILLO DE RODADURA EXTERIOR INCLUYE UN REBAJE QUE SE EXTIENDE ALREDEDOR DE SU PERIFERIA EXTERIOR. UNA ESTRUCTURA SELLADORA ENCAJA EN FORMA DESLIZABLE CON EL REBAJE PARA PROVEER UN SELLO ENTRE EL CONO Y EL VÁSTAGO.<br />
