Abstract
Incluye un brazo compuesto por un tramo superior (2) cuyo extremo superior (3) se vincula a una placa (1) fijable al chasis de la sembradora. Su extremo inferior (3a) se vincula con una porción superior (4) mediante un tramo intermedio (4a) en el que se provee un punto de anclaje (5) en el que articula uno de los extremos de un cuerpo curvo (6). El extremo restante articula y se fija a un punto de anclaje inferior (7) provisto en el tramo inferior (8) del brazo. El extremo inferior (9) de dicho tramo inferior (8) se vincula a un cuerpo cilíndrico (10) provisto con un eje (11) interno vinculado a un plato (15) conformado en el extremo superior de una horquilla (14) que provee un eje horizontal (13) para una rueda (12). En la zona media del cuerpo curvo (6) se conforma un tercer punto de anclaje (16) para el vástago (17) de un cilindro hidráulico cuyo cuerpo (18) se fija a correspondientes orejas (19) proyectadas de los laterales del tramo superior (2) del brazo. Incluye asimismo un circuito hidráulico compuesto por un primer bloque (I) que incluye una válvula reguladora del caudal (20) divisor del flujo proveniente de una de las válvulas distribuidoras de dos vías (a) entre dos cilindros (21) que operan el levante central y del cual se deriva hacia sendos segundos cilindros (22) que operan el levante de las alas; cuyo segundo bloque (II) comprende una segunda válvula reguladora del caudal (23) alimentada desde una de las válvulas distribuidoras de dos vías (a) y vinculada a un tercer cilindro (24) que provee una salida (25) que se bifurca vinculándose con un cuarto cilindro (26) y una barra móvil (27). Un cuarto cilindro (26) se vincula con una tercera válvula reguladora del caudal (28) y la barra móvil (27) con una cuarta válvula reguladora del caudal (29). Un tercer bloque (III) está alimentado por una de las válvulas distribuidoras de dos vías (a) que deriva el flujo hacia una quinta válvula reguladora del caudal (30) que lo divide entre el cilindro de apertura del ala derecha (31) y el cilindro de apertura del ala izquierda (32). El cilindro de apertura del ala derecha (31) provee una conexión a un cilindro de apertura de ruedas (33) y el cilindro de apertura del ala izquierda (32) provee una conexión a un segundo cilindro de apertura de ruedas (34). El cuarto bloque (IV) presenta una sexta válvula reguladora del caudal (35) proveniente de una de las válvulas distribuidoras de dos vías (a) dividiéndolo entre un cilindro de rueda trasera (36) y un segundo cilindro de rueda trasera (37). El circuito hidráulico incluye una pluralidad de válvulas distribuidoras de dos vías (a) vinculadas con una correspondiente pluralidad de conexiones donde una primera conexión (A) actúa sobre la traba de lanza, una segunda conexión (B) sobre la regulación de lanza, una tercera conexión (C) con el pliegue de las alas, una cuarta conexión (D) con el levante y trabajo al igual que una quinta conexión (E) y una sexta conexión (F) actúa sobre la cuchilla móvil.It includes an arm composed of an upper section (2) whose upper end (3) is linked to a plate (1) that can be fixed to the chassis of the planter. Its lower end (3a) is linked to an upper portion (4) by means of an intermediate section (4a) in which an anchor point (5) is provided in which one of the ends of a curved body (6) articulates. The remaining end articulates and is fixed to a lower anchor point (7) provided in the lower section (8) of the arm. The lower end (9) of said lower section (8) is linked to a cylindrical body (10) provided with an internal shaft (11) linked to a plate (15) formed at the upper end of a fork (14) that provides a horizontal axis (13) for a wheel (12). In the middle area of the curved body (6) a third anchoring point (16) is formed for the rod (17) of a hydraulic cylinder whose body (18) is fixed to corresponding ears (19) projected from the sides of the upper section (2) of the arm. It also includes a hydraulic circuit composed of a first block (I) that includes a flow regulating valve (20) that divides the flow from one of the two-way distribution valves (a) between two cylinders (21) that operate the central lift. and from which it derives towards two second cylinders (22) that operate the lift of the wings; whose second block (II) comprises a second flow regulating valve (23) fed from one of the two-way distribution valves (a) and linked to a third cylinder (24) that provides an outlet (25) that bifurcates linking with a fourth cylinder (26) and a movable rod (27). A fourth cylinder (26) is linked to a third flow control valve (28) and the moving rod (27) with a fourth flow control valve (29). A third block (III) is fed by one of the two-way distribution valves (a) that diverts the flow to a fifth flow regulating valve (30) that divides it between the opening cylinder of the right wing (31) and the left wing opening cylinder (32). The right wing opening cylinder (31) provides a connection to one wheel opening cylinder (33) and the left wing opening cylinder (32) provides a connection to a second wheel opening cylinder (34). The fourth block (IV) has a sixth flow regulating valve (35) coming from one of the two-way distribution valves (a) dividing it between a rear wheel cylinder (36) and a second rear wheel cylinder (37). The hydraulic circuit includes a plurality of two-way distribution valves (a) linked to a corresponding plurality of connections where a first connection (A) acts on the lance lock, a second connection (B) on the lance regulation, a third connection (C) with the fold of the wings, a fourth connection (D) with the lift and work as well as a fifth connection (E) and a sixth connection (F) acts on the movable blade.
