Description

SUPPORT FOR AGRICULTURAL GRADES DISCS

OBJETO DE LA INVENCION OBJECT OF THE INVENTION

La presente invenci6n se refiere a un soporte para discos de gradas agricolas, utilizadas estas en el laboreo de tierras, cualquiera que sea el estado de las mismas, ya sean rastrojos, vinas, etc. The present invention relates to a support for agricultural harrow discs, used in the tillage of lands, whatever their status, be they stubble, wine, etc.

El objeto de la invenci6n es conseguir una simplificaci6n en el montaje de los discos y una gran resistencia del conjunto. The object of the invention is to achieve a simplification in the assembly of the discs and a great resistance of the assembly.

ANTECEDENTES DE LA INVENCION BACKGROUND OF THE INVENTION

Como es sabido, los discos de gradas para laboreo de tierra van montados sobre correspondientes bujes dotados de rodamientos internos para el giro de los propios discos, de manera tal que el soporte que constituye el buje en cada caso va fijado a un brazo que por su otro extremo se vincula al correspondiente vehiculo tractor. As is known, the ground tillage discs are mounted on corresponding bushings equipped with internal bearings for the rotation of the discs themselves, so that the support that constitutes the bushing in each case is fixed to an arm that by its Another end is linked to the corresponding tractor vehicle.

El inconveniente que presentan los sistemas conocidos de amarre de los discos al brazo vinculable al tractor, es que para cada disco existe un buje, lo que supone un coste econ6mico considerable, teniendo en cuenta que una grada suele contar con una pluralidad de discos. The drawback presented by the known systems for tying the discs to the linkable arm to the tractor, is that for each disc there is a hub, which implies a considerable economic cost, taking into account that a tier usually has a plurality of discs.

DESCRIPTION OF THE INVENTION

El soporte que se preconiza ha sido concebido para resolver la problematica anteriormente expuesta, en base a una soluci6n sencilla pero eficaz, ya que el soporte esta previsto para montar dos discos en un mismo conjunto, es decir con un unico buje o eje de giro para ambos discos, lo que evidentemente supone un abaratamiento en el coste econ6mico del conjunto final, ademas de otras prestaciones y ventajas que se iran exponiendo a lo largo de la presente descripci6n. The support that has been recommended has been designed to solve the problem described above, based on a simple but effective solution, since the support is intended to mount two discs in the same set, that is to say with a single bushing or axis of rotation for both discs, which evidently implies a reduction in the economic cost of the final set, in addition to other benefits and advantages that will be exposed throughout the present description.

Mas concretamente el soporte de la invenci6n presenta la particularidad de que la pieza de amarre al brazo vinculable al vehiculo tractor es una pieza unica en la que esta establecido el correspondiente buje con un eje unico pero previsto para montaje simultaneo de dos discos de diferente diametro. More specifically, the support of the invention has the particularity that the mooring piece to the arm linked to the tractor vehicle is a unique part in which the corresponding hub with a single axle but intended for simultaneous assembly of two discs of different diameter is established.

Ademas, el amarre entre esa pieza soporte de los discos y el brazo fijable al vehiculo tractor, puede ser fija o incluso ser un amarre variable en posici6n, lo que permite variar la angulaci6n de trabajo de los propios discos. In addition, the mooring between that support part of the disks and the arm that can be fixed to the towing vehicle can be fixed or even be a variable mooring in position, which makes it possible to vary the working angle of the disks themselves.

En definitiva, se trata de un soporte que permite simplificar la construcci6n del conjunto, utilizando ademas un unico buje o pieza para dos discos. In short, it is a support that simplifies the construction of the assembly, also using a single bushing or part for two discs.

Tambien es de destacar el hecho de que al estar el eje constituido por una unica pieza para los dos discos, se posibilita el que la longitud pueda ser mayor o menor y por lo tanto disponer los rodamientos con mayor separaci6n, lo que posibilita conseguir una gran resistencia del conjunto. Also noteworthy is the fact that since the shaft is made up of a single piece for the two discs, it is possible that the length can be greater or lesser and therefore have the bearings with greater separation, which makes it possible to achieve a large set resistance.

o buje. or bushing

La figura 3.- Muestra una vista como la de la figura 1, pero donde el amarre entre el soporte y el brazo vinculable al vehiculo tractor es invariable. Figure 3.- Shows a view like that of figure 1, but where the tie between the support and the linkable arm to the tractor vehicle is invariable.

PREFERRED EMBODIMENT OF THE INVENTION

Como se puede ver en las figuras referidas, y en relaci6n concretamente con las figuras 1 y 2, puede observarse como el soporte de la invenci6n esta constituido por una pieza unica en la que esta conformado el correspondiente buje (1) con un eje de giro comun para dos discos (2, 2'), de diferente diametro, que han de montar sobre ese buje (1), concretamente sobre el eje interior a tal buje (1), efectuandose la fijaci6n de los discos (2, 2') mediante tornillos roscables en respectivas valonas (3). As can be seen in the aforementioned figures, and specifically in relation to figures 1 and 2, it can be seen how the support of the invention is constituted by a single piece in which the corresponding bushing (1) is formed with an axis of rotation common for two disks (2, 2 '), of different diameter, to be mounted on that hub (1), specifically on the inner shaft to such bushing (1), fixing the disks (2, 2') by means of threaded screws in respective walls (3).

Ese soporte general esta previsto para su fijaci6n al correspondiente brazo (4) con una parte extrema o cabezal (5) para su fijaci6n al correspondiente vehiculo tractor, mientras que en la parte opuesta incluye una placa (6) para que mediante tornillos (7) se fije al soporte descrito, contando la placa (6) y el soporte con orificios enfrentables (8) que de acuerdo con la posici6n que ocupen, permite variar la posici6n angular entre el brazo (4) y el soporte, ypor tanto variar la inclinaci6n de los propios discos (2, 2'). This general support is provided for fixing to the corresponding arm (4) with an end part or head (5) for fixing to the corresponding tractor vehicle, while on the opposite part it includes a plate (6) so that by means of screws (7) be fixed to the described support, counting the plate (6) and the support with facing holes (8) that according to the position they occupy, allows to vary the angular position between the arm (4) and the support, and therefore vary the inclination of the discs themselves (2, 2 ').

Aunque no forma parte de la invenci6n, decir que el brazo (4) contara con un medio de amortiguaci6n que puede estar constituido por uno Although not part of the invention, say that the arm (4) will have a damping means that may be constituted by one

o varios muelles (9), como se representa en la figura 1, o bien ser sustituido este muelle (9) por un hidraulico, ya que la funci6n es la de conseguir una amortiguaci6n para posibilitar el salto de los discos durante su trabajo en la tierra, cuando encuentran un obstaculo duro. or several springs (9), as shown in figure 1, or this spring (9) be replaced by a hydraulic one, since the function is to achieve a damping to enable the discs to jump during their work in the earth, when they find a hard obstacle.

En una variante de realizaci6n mostrada en la figura 3, el amarre entre el brazo (4) y el soporte o pieza en la que esta materializado el buje (1), es invariable en posici6n, no existiendo los orificios (8) anteriormente comentados que permitian variar la posici6n angular entre brazo (4) y soporte o buje (1), y con ello variar la angulaci6n de trabajo de los discos (2, 2'). In a variant embodiment shown in Figure 3, the tie between the arm (4) and the support or part in which the bushing (1) is materialized, is invariably in position, the holes (8) previously mentioned not existing that allowed to vary the angular position between arm (4) and support or bushing (1), and thereby vary the working angle of the disks (2, 2 ').
