Abstract

REGLAGE AUTOMATIQUE D'UNE POSITION ETOU D'UNE RESISTANCE D'OUTIL DE TRAVAIL. UNE MACHINE AGRICOLE EST EQUIPEE D'UN DISPOSITIF QUI COMPARE LES IMPULSIONS PROVENANT DE GENERATEURS DE VALEURS DE CONSIGNE 24, 26 A CELLES PROVENANT DE GENERATEURS DE VALEURS REELLES 25, 27. UN GROUPE DE COMMANDE HYDRAULIQUE OU PNEUMATIQUE 29, 31, 32, 42, 43, 44, CAPABLE DE CONVERTIR EN PRESSION L'ENERGIE CINETIQUE DE JETS, EST ASSOCIE DIRECTEMENT AUX GENERATEURS DE VALEURS REELLES 25, 27 POUR ACTIONNER UN SERVO-DISTRIBUTEUR 11. APPLICATION: REGLAGE DE LA PROFONDEUR D'OUTILS A L'AIDE D'UN VERIN HYDRAULIQUE 17, 18.AUTOMATIC ADJUSTMENT OF A POSITION ANDOR OF A WORK TOOL RESISTANCE. AN AGRICULTURAL MACHINE IS EQUIPPED WITH A DEVICE WHICH COMPARES THE PULSES FROM GENERATORS OF SET VALUES 24, 26 WITH THOSE FROM GENERATORS OF ACTUAL VALUES 25, 27. A HYDRAULIC OR PNEUMATIC CONTROL UNIT 29, 31, 32, 42, 43, 44, CAPABLE OF CONVERTING THE KINETIC ENERGY OF JETS INTO PRESSURE, IS ASSOCIATED DIRECTLY WITH GENERATORS OF ACTUAL VALUES 25, 27 TO ACTUATE A SERVO-DISTRIBUTOR 11. APPLICATION: ADJUSTING THE DEPTH OF TOOLS USING A HYDRAULIC CYLINDER 17, 18.
