Abstract

Agricultural cultivating machine, of which they consist of a frame-frame (1) with several crosspieces (2) in each of which a plurality of arms (3) carrying the cultivar discs (4) are mounted. Each arm (3) is mounted on the corresponding crossbar (2) with interposition of a spring (7); so that the disc (4) and its arm (3) can move spatially in any direction with respect to the crosspiece (2) when the presence of an obstacle causes deformation of the leaf spring (7). Each arm (3), which mounts a single cultivator disk (4), has a very open "V" configuration, with wings (30a), (30b) asymmetrical and offset by an angle (β). In one of the wings (30a) the leaf spring (7) is assembled and from the other (30b) an independent axis (31) with an angular offset (α) emerges towards one side with respect to it, thereby simultaneously spatial displacement of the arms (3), the cultivar discs (4) also vary their horizontal/vertical inclination with respect to the ground.

La máquina agrícola de cultivar, de acuerdo con el invento, es de las que constan de un armazón-bastidor (1) con varios travesaños (2) en cada uno de los cuales se montan una pluralidad de brazos (3) portadores de los discos de cultivar (4). The agricultural cultivating machine, according to the invention, is one of those consisting of a frame-frame (1) with several crossbars (2) on each of which a plurality of arms (3) carrying the discs are mounted to cultivate (4).

De conformidad con la invención, y según la realización representada cada brazo (3) se monta en un travesaño (2) con interposición de una ballesta (7). In accordance with the invention, and according to the embodiment shown, each arm (3) is mounted on a crossbar (2) with interposition of a crossbow (7).

Para la realización representada, cada ballesta (7) presenta configuración en arco asimétrico y se monta firmemente fijada al travesaño (2) por uno de sus extremos (72) y 5 al brazo (3) por su otro extremo (73). La particular configuración de las ballestas (7) en arco asimétrico, propician este montaje ocupando un mínimo espacio: las ballestas (7) salvan al travesaño (2) abrazándolo de tal forma que los discos de cultivar (4) quedan posicionalmente próximos al travesaño (2) del que dependen (en una configuración general de la máquina dimensionalmente muy aproximada a las medidas idóneas que se For the embodiment shown, each crossbow (7) has an asymmetric arch configuration and is mounted firmly fixed to the crossbar (2) by one of its ends (72) and 5 to the arm (3) by its other end (73). The particular configuration of the crossbows (7) in an asymmetric arch, facilitate this assembly occupying a minimum space: the crossbows (7) save the crossbar (2) hugging it in such a way that the cultivation discs (4) are positionally close to the crossbar ( 2) on which they depend (in a general configuration of the machine dimensionally very close to the ideal measures that are

Con esta estructura, componentes y disposición: With this structure, components and layout:

Cada brazo (3) es portador de un disco de cultivar (4) y se relaciona con un travesaño (2) mediante una ballesta (7). Each arm (3) is a carrier of a cultivation disk (4) and is related to a crossbar (2) by means of a crossbow (7).

15 Cada brazo (3) se monta en un soporte (2) con posibilidad de desplazamiento espacial en cualquier dirección cuando el disco de cultivar (4) encuentra un obstáculo (independientemente de la dirección que ataque dicho obstáculo. Each arm (3) is mounted on a support (2) with the possibility of spatial displacement in any direction when the cultivation disc (4) encounters an obstacle (regardless of the direction that the obstacle attacks.

De conformidad con la invención, y según la realización representada cada brazo (3) presenta configuración alargada ligeramente acodada, asemejando una "V" muy abierta In accordance with the invention, and according to the embodiment shown, each arm (3) has a slightly elongated elongated configuration, resembling a very open "V"

20 de alas (30a), (30b) asimétricas, desfasadas entre sí una amplitud angular (13). 20 of wings (30a), (30b) asymmetric, offset one another angular width (13).

El ala mayor (30a) del brazo (3) lleva fijada la correspondiente ballesta (7) en su extremo mediante la unión fija (72) antes citada. The major wing (30a) of the arm (3) has the corresponding crossbow (7) attached at its end by means of the aforementioned fixed joint (72).

La otra ala (30b) del brazo (3) dispone un eje (31) independiente, que emerge hacia un lado con un desfase angular (o) respecto a ella. The other wing (30b) of the arm (3) has an independent shaft (31), which emerges to one side with an angular offset (or) with respect to it.

25 El hecho de que los desfases angulares (o) de los ejes (31) portadores de los discos de cultivar (4) sean iguales en todos los brazos (3) o diferentes en unos brazos que en otros se traduce en que las inclinaciones de los discos de cultivar (4) respecto a su correspondiente brazo (3) sean iguales o diferentes, pero no altera la esencia del invento. 25 The fact that the angular offsets (or) of the axes (31) bearing the cultivation discs (4) are the same in all the arms (3) or different in some arms that in others means that the inclinations of the cultivation discs (4) with respect to their corresponding arm (3) are the same or different, but it does not alter the essence of the invention.

La peculiar disposición de los ejes (31) en los brazos (3) provoca una variación de la 30 inclinación angular vertical de los discos de cultivar (4) respecto al suelo, inclinación angular vertical que es simultánea, independiente y adicional de la inclinación angular que se obtiene al desplazarse espacialmente el brazo (3) por la deformación de la ballesta (7) cuando se encuentra un obstáculo. The peculiar arrangement of the axes (31) in the arms (3) causes a variation of the vertical angular inclination of the cultivation discs (4) with respect to the ground, vertical angular inclination that is simultaneous, independent and additional of the angular inclination which is obtained by spatially moving the arm (3) by deformation of the crossbow (7) when an obstacle is encountered.

Con esta estructura, componentes y disposición, el desplazamiento espacial del propio 5 brazo (3) al detectarse un obstáculo proporciona, además, una variación de la inclinación horizontal/vertical de los discos (4) respecto al suelo. With this structure, components and arrangement, the spatial displacement of the arm itself (3) when an obstacle is detected also provides a variation of the horizontal / vertical inclination of the disks (4) with respect to the ground.

Podrán ser variables los materiales, dimensiones, proporciones y, en general, aquellos otros detalles accesorios o secundarios que no alteren, cambien o modifiquen la esencialidad propuesta. The materials, dimensions, proportions and, in general, those other accessory or secondary details that do not alter, change or modify the proposed essentiality may be variable.
