Abstract

MECANISMO HIDRAULICO DE ELEVACION PARA IMPLEMENTOS O APEROS ACOPLADOS A TRACTORES AGRICOLAS. EL APERO DE TRABAJO (3) SE ACCIONA MEDIANTE UN CILINDRO ELEVADOR (4), QUE A TRAVES DE UNA TUBERIA DE PRESION (5), Y MEDIANTE UNA VALVULA DE REGULACION (6), ESTA UNIDO A UNA BOMBA DE ALTA PRESION (7) ACCIONADA POR EL MOTOR DEL TRACTOR; ADEMAS HAY UN DEPOSITO (8), Y EN EL PUESTO DE MANIOBRA DEL TRACTOR HAY UN APARATO DE MANDO (11), QUE CONSTA DE UNA VALVULA LIMITADORA DE PRESION (34), UNA VALVULA DE MANDO PREVIO (14) Y UNA VALVULA DE EXTRACCION (13), PARA LA REGULACION DE LA ALTURA DE TRABAJO. EL APARATO DE MANDO Y LA VALVULA DE REGULACION ESTAN UNIDAS A UNA VALVULA DE COMPARACION (17), COLOCADA SOBRE EL APERO DE TRABAJO, QUE TANTEA LA SUPERFICIE DEL SUELO MEDIANTE UN SENSOR DE ALTURAS (18).
