Abstract
SISTEMA DE CONTROL PARA TRACTORES CON APARATO DE TRABAJO ENGANCHADO. SE DESCRIBE UN SISTEMA DE CONTROL PARA UN TRACTOR (10) QUE CONTIENE UN DISPOSITIVO DE ACOPLAMIENTO (15) REGULABLE EN ALTURA Y UN APARATO DE TRABAJO ENGANCHABLE (40), QUE LLEVA UTILES DE CULTIVADORES REGULABLES EN ALTURA (46). EL SISTEMA DE CONTROL COMPRENDE UNA BOMBA HIDRAULICA (20), UN DEPOSITO DE RESERVA (22), UN CILINDRO DE EJE ELEVADOR (12) PARA ELEVAR Y BAJAR EL DISPOSITIVO DE ACOPLAMIENTO (15), UNA VALVULA DE CONTROL DE ELEVACION (16) PARA EL AJUSTE DEL PASO DEL LIQUIDO HACIA EL CILINDRO DEL EJE ELEVADOR (12), UNA UNIDAD DE MANDO (30) PARA EL CONTROL DE LA VALVULA DE CONTROL DE ELEVACION (16) EN FUNCION DE LOS VALORES MEDIDOS (34, 36) Y AL MENOS UNA SEÑAL DE CONTROL AJUSTABLE (32), UN CILINDRO DE APARATO DE TRABAJO (48) PARA ELEVAR Y BAJAR LOS UTILES CULTIVADORES (46) DEL APARATO DE TRABAJO ENGANCHABLE (40) Y UNA VALVULA DE CONMUTACION (50) AJUSTABLE MANUALMENTE AL MENOS ENTRE DOS POSICIONES PARA LA CONEXION OPCIONALDEL CILINDRO DEL APARATO DE TRABAJO (48) A LA VALVULA DE CONTROL DE ELEVACION (16). PARA ELEVAR EL DISPOSITIVO DE ACOPLAMIENTO (15) AUTOMATICAMENTE A LA POSICION SUPERIOR, EN CUANTO SE CONSTITUYA UN CIRCUITO REGULADOR CERRADO PARA EL CILINDRO DEL APARATO DE TRABAJO (48), SE PROPONE QUE EN LA PRIMERA POSICION DE LA VALVULA DE CONMUTACION (50) SE ESTABLEZCA A TRAVES DE ESTA UNA CONEXION DIRECTA ENTRE LA BOMBA HIDRAULICA (20) Y EL CILINDRO DEL APARATO DE TRABAJO (48) ASI COMO UNA CONEXION ENTRE EL EMPALME DE TRABAJO (18) DE LA VALVULA DE CONTROL DE ELEVACION (16) Y EL CILINDRO DE EJE ELEVADOR (12). ADEMAS, EN UNA SEGUNDA POSICION DE LA VALVULA DE CONMUTACION (50) SE ESTABLEZCA A TRAVES DE ESTA UNA CONEXION DIRECTA ENTRE LA BOMBA HIDRAULICA (20) Y EL CILINDRO DEL EJE ELEVADOR (12) ASI COMO UNA CONEXION ENTRE EL EMPALME DE TRABAJO (18) DE LA VALVULA DE CONTROL DE ELEVACION (16) Y EL CILINDRO DEL APARATO DE TRABAJO (48).
