La presente invención está relacionada con el desbrozado de maleza vegetal mediante máquinas autopropulsadas, proponiendo una barra de corte que permite abatir cualquier tipo de maleza para abrir camino por delante de la máquina portadora correspondiente.The present invention is related to the clearing of weeds using self-propelled machines, proposing a cutter bar that allows to reduce any type of weed to make way ahead of the carrier correspondent.
Es conocida la práctica de eliminación de malezas, árboles y arbustos, para la limpieza de terrenos, con el fin de abrir pasos de circulación, cortafuegos, o simplemente para facilitar el trabajo de máquinas que tengan que operar sobre la zona implicada.The elimination practice of weeds, trees and shrubs, for cleaning land, with the in order to open traffic passages, firewalls, or simply to facilitate the work of machines that have to operate on the area involved
Para la eliminación de los obstáculos vegetales en esas prácticas existen máquinas provistas con medios de corte que permiten abatir malezas, arbustos y árboles en una franja de circulación, a medida que la máquina avanza.For the removal of plant obstacles in these practices there are machines provided with cutting means which allow weeds, bushes and trees to be laid down in a strip of circulation, as the machine advances.
En este sentido, la Patente ES 9402277, referida a una máquina para la extinción de incendios mediante lanzamiento de tierra, dispone por delante de la máquina un rodillo giratorio provisto con cuchillas en su periferia, de forma que al avanzar la máquina dicho rodillo corta los elementos vegetales que encuentra, dejando un camino despejado para el paso de la máquina.In this regard, Patent ES 9402277, referred to to a fire extinguishing machine by launch ground, has a rotating roller in front of the machine provided with blades on its periphery, so that as the said roller machine cuts the plant elements it finds, leaving a clear path for the passage of the machine.
Debido a los grandes esfuerzos que debe soportar el mencionado rodillo de corte en su función, sobre todo para el corte de árboles, se requieren unas condiciones estructurales muy especiales para evitar atascos y roturas, lo cual no se halla satisfactoriamente resuelto en las realizaciones propuestas hasta el momento al respecto.Because of the great efforts you must endure the aforementioned cutting roller in its function, especially for the tree cutting, very structural conditions are required special to avoid jams and breaks, which is not found satisfactorily resolved in the proposed embodiments until moment about it.
De acuerdo con la invención se propone se una barra de corte destinada para la aplicación en máquinas desbrozadoras o similares, la cual se ha desarrollado con unas características constructivas y funcionales que la hacen particularmente ventajosa para esa función.According to the invention it is proposed to be a cutting bar intended for application in machines Brushcutters or similar, which has been developed with some constructive and functional characteristics that make it particularly advantageous for that function.
Esta barra objeto de la invención consta de un cuerpo rotatorio provisto con cuchillas en la periferia, componiéndose dicho cuerpo de dos o más tramos longitudinales axialmente consecutivos, en montaje independiente de dichos tramos sobre un soporte común, con medios de accionamiento giratorio individual de cada uno de los tramos.This bar object of the invention consists of a rotating body provided with blades on the periphery, said body being composed of two or more longitudinal sections axially consecutive, in independent assembly of said sections on a common support, with rotating drive means individual of each of the sections.
Se obtiene así un medio de corte muy resistente y de gran potencia, ya que la composición del elemento de corte en tramos parciales sujetos individualmente por sus extremos, evita la flexión y doblado por los esfuerzos contra los elementos a cortar; en tanto que el accionamiento giratorio individual de cada uno de los tramos, permite aplicar un par de giro de gran fuerza para la acción del corte.This results in a very resistant cutting medium and of great power, since the composition of the cutting element in partial sections subject individually by their ends, avoid bending and bending by efforts against the elements to be cut; while the individual rotary drive of each of the sections, allows to apply a torque of great force for the cutting action.
Con estas características la barra de corte preconizada permite cortar con efectividad troncos de árbol del orden de treinta centímetros de diámetro, de modo que las máquinas de aplicación pueden ser utilizadas para operaciones de desbroces vegetales de cualquier tipo, prácticamente sin limitaciones.With these features the cutter bar recommended to effectively cut tree trunks from order of thirty centimeters in diameter, so that the machines of application can be used for clearing operations Vegetables of any kind, practically without limitations.
En las partes extremas e intermedias del soporte, sobre las que se establece el montaje de los tramos del cuerpo rotatorio que constituye el elemento de corte, se disponen unos rodillos frontales, los cuales hacen de topes de orientación respecto de los troncos de árboles que coincidan con dichas partes durante el avance en las operaciones de trabajo.In the extreme and intermediate parts of the support, on which the assembly of the sections of the rotating body that constitutes the cutting element, are arranged front rollers, which make orientation stops with respect to tree trunks that match those parts during the progress in work operations.
De este modo se evita la posibilidad de detenciones del avance por tope contra los troncos de árboles que coincidan con las zonas de la parte frontal del soporte en las que no actúa el medio de corte, ya que ante esas circunstancias el rodillo frontal correspondiente hace desviarse ligeramente a la máquina, con lo que el tronco de árbol causante del obstáculo va a una de las zonas en las que actúa el medio de corte, de manera que es cortado desapareciendo el obstáculo.This avoids the possibility of stops of the advance by butt against the trunks of trees that match the areas of the front of the support where the means of court does not act, since under these circumstances the corresponding front roller slightly deviates from the machine, so that the tree trunk causing the obstacle is going to one of the areas where the cutting means acts, so that It is cut disappearing the obstacle.
Por todo ello, la barra de corte objeto de la invención resulta de unas características ciertamente ventajosas, adquiriendo vida propia y carácter preferente para la función de aplicación a la que se halla destinada.Therefore, the cutter bar object of the invention results from certainly advantageous features, acquiring own life and preferential character for the function of application to which it is intended.
La figura 1 muestra en perspectiva un ejemplo de la barra de corte preconizada, sobre el soporte correspondiente.Figure 1 shows in perspective an example of the recommended cutting bar, on the support correspondent.
La figura 2 es una vista en planta del conjunto de la figura anterior, con el soporte de la barra seccionado.Figure 2 is a plan view of the assembly of the previous figure, with the support of the sectioned bar.

La barra preconizada consta de un cuerpo rotatorio (1) provisto con cuchillas en la periferia, en montaje sobre un soporte (2) que incluye los medios (no representados) de acoplamiento a la máquina de aplicación, y en el que se instalan los medios actuadores del accionamiento giratorio del cuerpo rotatorio (1).The recommended bar consists of a body rotary (1) provided with blades on the periphery, in assembly on a support (2) that includes the means (not shown) of coupling to the application machine, and in which they are installed the actuator means of the rotary drive of the body rotary (1).
Según la invención, el cuerpo rotatorio (1) provisto con cuchillas se compone de dos o más tramos longitudinales (1.1), los cuales se disponen montados de manera independiente en el soporte (2), entre unas conformaciones extremas e intermedias (2.1) de la parte frontal de dicho soporte (2), lo cual determina una gran resistencia del mencionado cuerpo (1) para la acción operativa en el trabajo de aplicación sobre los elementos a cortar.According to the invention, the rotary body (1) provided with blades consists of two or more sections longitudinal (1.1), which are arranged so mounted independent in the support (2), between extreme conformations and intermediate (2.1) of the front part of said support (2), the which determines a high resistance of said body (1) to the operational action in the application work on the elements to cut.
Los tramos componentes (1.1) del cuerpo rotatorio (1), disponen a su ve de medios individuales de accionamiento giratorio, mediante correspondientes motores (3) y respectivas transmisiones reductoras (4), lo cual permite una gran potencia del accionamiento de los mencionados tramos (1.1) para la función de los cortes en el trabajo de aplicación.The component sections (1.1) of the body rotary (1), have individual means of rotary drive, by means of corresponding motors (3) and respective reducing transmissions (4), which allows a large drive power of the mentioned sections (1.1) for the function of the cuts in the application work.
Según la invención, en la parte frontal de las conformaciones extremas e intermedias (2.1) del soporte (2), entre las que se establece el montaje de los tramos (1.1) constitutivos del elemento de corte, se disponen unos rodillos (5), los cuales hacen de topes de choque en esa zona frontal del soporte (2).According to the invention, on the front of the extreme and intermediate conformations (2.1) of the support (2), between which establishes the assembly of the constituent sections (1.1) of the cutting element, rollers (5) are arranged, which they make shock stops in that front area of the support (2).
Con ello, cuando en la acción del trabajo de aplicación el conjunto de la barra de corte encuentra un tronco de árbol coincidiendo con alguna de las conformaciones (2.1), cuyo espacio se halla fuera de la acción del elemento de corte, el rodillo (5) correspondiente hace un tope deslizante sobre el tronco de árbol, obligando a una ligera desviación de la máquina, con lo cual el tronco de árbol va a la zona de acción de uno de los tramos (1.1) del elemento de corte, en donde dicho tronco de árbol es cortado.With that, when in the work action of application the cutter bar assembly finds a trunk of tree coinciding with some of the conformations (2.1), whose space is outside the action of the cutting element, the corresponding roller (5) makes a sliding stop on the trunk of tree, forcing a slight deviation of the machine, with what which tree trunk goes to the zone of action of one of the sections (1.1) of the cutting element, wherein said tree trunk is chopped up.
De esta manera se evita la circunstancia de la
posible detención del avance en el trabajo de aplicación por choque
contra los árboles que se encuentran en el recorrido de actuación,
ya que cuando esto ocurre los rodillos frontales (5) obligan a una
ligera desviación de la máquina, con lo que los árboles que
coinciden en tales circunstancias son cortados, evitándose
su
obstáculo.In this way the circumstance of the possible stop of the advance in the work of application by shock against the trees that are in the course of action is avoided, since when this occurs the front rollers (5) force a slight deviation of the machine, with which the trees that coincide in such circumstances are cut, avoiding their
obstacle.
