Description

HERRAMIENTA PARA ACOPLAR A UN VEHíCULO AGRíCOLA TOOL FOR COUPLING AN AGRICULTURAL VEHICLE

S S
La presente invención se refiere a una herramienta para acoplar a un vehiculo agrícola, en particular a una herramienta alisadora acoplable a la parte delantera de un vehiculo con el fin de preparar el terreno al paso de las ruedas del vehículo. The present invention relates to a tool for attaching an agricultural vehicle, in particular to a smoothing tool that can be attached to the front of a vehicle in order to prepare the ground for passing the wheels of the vehicle.

A menudo los terrenos son muy irregulares y presentan piedras y terrones que dificultan el paso de las ruedas de un vehículo, provocando daños en los neumáticos, vibraciones incómodas, problemas de tracción y deterioro de los sistemas de suspensión de los vehículos, limitando la velocidad de trabajo y aumentando el coste debido tanto al mayor consumo de combustible como a la necesidad de mantenimiento. Often the terrain is very irregular and has stones and lumps that hinder the passage of the wheels of a vehicle, causing damage to the tires, uncomfortable vibrations, traction problems and deterioration of the vehicle suspension systems, limiting the speed of work and increasing the cost due to both the higher fuel consumption and the need for maintenance.

A la hora de trabajar con estos vehículos seria deseable que el terreno estuviera en las mejores condiciones posibles en referencia al allanado del terreno, sin obstáculos tales como piedras o terrones. When working with these vehicles, it would be desirable for the terrain to be in the best possible conditions in reference to the leveling of the terrain, without obstacles such as stones or lumps.

El bastidor (1) está conformado por un primer armazón (2) esencialmente The frame (1) is formed by a first frame (2) essentially

rectangular que se prolonga lateralmente hacia su parte posterior, esto es hacia el rectangular that extends laterally towards its back, this is towards the

vehlculo, mediante correspondientes escuadras laterales (3, 4), definiendo así dos vehicle, by means of corresponding lateral squares (3, 4), thus defining two

1S caras laterales triangulares acopladas al primer armazón. Este primer armazón (2) incluye asimismo dos travesMos (5, 6) paralelos a los laterales verticales del armazón (2) que sirven como refuerzo del bastidor (1) y como base para dos proyecciones triangulares (7, 8) que se extienden también hacia la parte posterior del bastidor (1), en dirección al vehículo, proyecciones (7, 8) que se unen a las 1S triangular side faces coupled to the first frame. This first frame (2) also includes two crossings (5, 6) parallel to the vertical sides of the frame (2) that serve as reinforcement of the frame (1) and as a base for two triangular projections (7, 8) that also extend towards the rear of the frame (1), in the direction of the vehicle, projections (7, 8) that join the

20 caras laterales (3, 4) antes c~adas. 20 side faces (3, 4) before each.

Desde el lado inferior de las caras laterales triangulares (3, 4) se proyectan verticalmente hacia abajo sendos soportes (9, 10) que terminan en correspondientes barquillas de alisado (11, 12). From the lower side of the triangular side faces (3, 4), two supports (9, 10) are projected vertically downwards, ending in corresponding straightening nozzles (11, 12).

Estas barquillas de alisado (11, 12) tienen esencialmente una forma triangular These smoothing waffles (11, 12) have essentially a triangular shape

25 hueca delimitada por dos paredes laterales (13, 14) acopladas formando un ángulo agudo por su parte delantera y abierta por su parte trasera, para evitar los obstáculos de la rodadura, ya que únicamente eliminan obstáculos de la rodadura debido a esa forma rectangular, incluyendo justo detrás una placa de fondo triangular (15) fundamental para el desarrollo de esta herramienta ya que continua 25 hollow delimited by two side walls (13, 14) coupled forming an acute angle at its front and open at its rear, to avoid rolling obstacles, since they only remove obstacles from the rolling due to that rectangular shape, including just behind a triangular bottom plate (15) essential for the development of this tool as it continues

30 el camino abierto por las barquillas, alisando el terreno y manteniendo la nivelación de las barquillas. Esta placa de fondo (15) se conforma esencialmente en forma de proa de barco, presentando al menos dos ángulos de inclínación 30 the road opened by the wafers, smoothing the ground and maintaining the leveling of the wafers. This bottom plate (15) is essentially shaped as a ship's bow, presenting at least two angles of inclination

diferentes con respecto a la normal (perpendicular al terreno). Como se observa en la figura, un primer ángulo proximal al vértice del triángulo definido por las different from normal (perpendicular to the terrain). As seen in the figure, a first angle proximal to the vertex of the triangle defined by the

caras laterales (13, 14) Y un segundo ángulo distal a dicho vértice, definiendo así para la placa de fondo (15) un diseño biselado en lo que constituiría un borde de ataque de las barquillas de alisado (11, 12). lateral faces (13, 14) And a second angle distal to said vertex, thus defining for the bottom plate (15) a beveled design in what would constitute a leading edge of the smoothing wafers (11, 12).

Las paredes laterales (13, 14) de las barquillas de alisado (11, 12), en particular su borde superior, constituyen un borde de fuga que coopera con sendas orejetas (16, 17) que se proyectan ligeramente hacia afuera desde la zona terminal de dicho borde superior. The side walls (13, 14) of the smoothing wafers (11, 12), in particular its upper edge, constitute a trailing edge that cooperates with lugs (16, 17) that project slightly outward from the terminal area of said upper edge.

Además, como se puede observar en la figura 3 en particular, la placa de fondo In addition, as can be seen in Figure 3 in particular, the bottom plate

(15) (fifteen)
de las barquillas de alisado (11,12) incluye una proyección rectangular plana of the smoothing wafers (11,12) includes a flat rectangular projection

(20) (twenty)
que se proyecta hacia la zona de las ruedas del vehiculo de forma esencialmente paralela al suelo y en uso que compacta, alisa y nivela el terreno y facilita la nivelación de las barquillas (11, 12). Como se observa en dicha figura 3, el borde lineal de la proyección (20) más cercano a las ruedas presenta una configuración ligeramente plegada hacia arriba con respecto al plano de la placa de fondo (15). which is projected towards the area of the wheels of the vehicle essentially parallel to the ground and in use that compacts, smooths and levels the ground and facilitates the leveling of the wafers (11, 12). As seen in said figure 3, the linear edge of the projection (20) closest to the wheels has a slightly folded configuration upwards with respect to the plane of the bottom plate (15).

Igualmente, el bastidor de herramienta (1) acoplable al vehiculo incluye correspondientes medios de anclaje liberables para el acoplamiento de la Likewise, the tool frame (1) attachable to the vehicle includes corresponding releasable anchoring means for coupling the

En una realización, entre los soportes (9, 10) Y los extremos opuestos al vértice de las barquillas (11,12) se disponen unos nervios de refuerzo (18,19) con el fin de mantener la integridad estructural y formal de las barquillas (11, 12) cuando éstas están en uso. In one embodiment, between the supports (9, 10) and the ends opposite the vertex of the wafers (11,12) reinforcement ribs (18,19) are arranged in order to maintain the structural and formal integrity of the wafers (11, 12) when they are in use.

En otra realización de la invención, las barquillas de alisado (11, 12) incluyen además un medio de corte (no mostrado) en su vértice delantero con el fin de In another embodiment of the invention, the smoothing waffles (11, 12) further include a cutting means (not shown) at its front vertex in order to
