Description

DESCRIPCIÓNDESCRIPTION

Desbrozadora de hilo hidráulicaHydraulic string trimmer

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a un equipo para el desbrozado de malas hierbas especialmente concebido para ser instalado en un vehículo tractor y facilitar las labores de desbrozado o desherbaje de grandes superficies de cultivo de plantas, como por ejemplo árboles frutales distribuidos en hileras.The present invention refers to equipment for weed clearing specially conceived to be installed on a tractor vehicle and to facilitate the work of clearing or weeding large areas of plant cultivation, such as fruit trees distributed in rows.

El objeto de la invención es proporcionar un equipo que permita realizar las labores de desherbaje de forma rápida, efectiva, cómoda y segura para las plantas cultivadas, a través de un equipo que no afecte negativamente ni a la maniobrabilidad ni a la potencia del vehículo en el que se instala.The object of the invention is to provide equipment that allows weeding tasks to be carried out quickly, effectively, comfortably and safely for the cultivated plants, through equipment that does not negatively affect the maneuverability or power of the vehicle in the one that is installed.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

En el ámbito de aplicación práctica de la invención, a la hora de eliminar las malas hierbas que puedan crecer alrededor de plantas tales como árboles frutales u otros cultivos existen dos tipos de equipos para llevar a cabo dicho desbrozado.In the field of practical application of the invention, when it comes to eliminating weeds that may grow around plants such as fruit trees or other crops, there are two types of equipment to carry out said brushing.

El primero de ellos consiste en las clásicas desbrozadoras manuales que, si bien resultan muy precisas a la hora de evitar dañar las plantas cultivadas, suponen un esfuerzo y una pérdida de tiempo muy importante si la superficie de cultivo es muy grande.The first of them consists of the classic manual brushcutters that, although they are very precise when it comes to avoiding damaging the cultivated plants, they involve a significant effort and waste of time if the cultivation area is very large.

Por otro lado se conocen equipos de implantación en vehículos tractores que, si bien permiten reducir drásticamente el tiempo de trabajo y esfuerzo necesario, presentan una problemática de la que caben destacar los siguientes aspectos:On the other hand, equipment for implantation in tractor vehicles are known which, although they allow drastically reducing the work time and necessary effort, present a problem of which the following aspects should be highlighted:

• Afectan muy negativamente a la maniobrabilidad del vehículo tractor.• They have a very negative effect on the maneuverability of the towing vehicle.

• Falta de precisión en su funcionamiento, lo que las hace inviables a la hora de desbrozar cultivos en los que las plantas cultivadas sean de pequeño tamaño o muy delicadas.• Lack of precision in their operation, which makes them unfeasible when clearing crops in which the cultivated plants are small or very delicate.

• Se trata de equipos que se alimentan de la toma de potencia del vehículo tractor, lo que obviamente reduce la potencia disponible para el propio vehículo, reduciendo por tanto sus prestaciones.• These are equipment that is fed from the power take-off of the towing vehicle, which obviously reduces the power available to the vehicle itself, thereby reducing its performance.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La desbrozadora de hilo hidráulica que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta en todos y cada uno de los aspectos comentados, permitiendo trabajar de forma precisa y segura alrededor de las plantas, incluso de muy pequeño grosor, cortando la hierba en el espacio entre los troncos de la misma fila, incluyendo su propia central hidráulica para su accionamiento, de forma independiente al vehículo sobre el que se implanta, y con una estructuración plegable que la hace muy maniobrable.The hydraulic wire brush cutter that is recommended solves in a fully satisfactory way the problems previously exposed in each and every one of the aforementioned aspects, allowing to work precisely and safely around the plants, even of very small thickness, cutting the grass in the space between the logs of the same row, including its own hydraulic unit for its operation, independently of the vehicle on which it is implanted, and with a folding structure that makes it very maneuverable.

Para ello, y de forma más concreta, el dispositivo de la invención se constituye a partir de dos bastidores destinados a instalarse sobre la parte anterior y posterior del vehículo tractor.For this, and more specifically, the device of the invention is made up of two frames intended to be installed on the front and rear of the towing vehicle.

En el bastidor de la parte posterior va montada una pequeña central hidráulica, encargada de alimentar los diferentes mecanismos de accionamiento del dispositivo, de forma totalmente independiente al sistema hidráulico del propio tractor.A small hydraulic unit is mounted on the rear frame, in charge of feeding the different drive mechanisms of the device, totally independent of the tractor's own hydraulic system.

Por su parte, el bastidor de la parte anterior, consiste en un marco o columna vertical sobre el que es desplazable verticalmente un carro que se vincula a un brazo en el que se establecen una pluralidad de cabezales de hilo destinados al desbrozado de las malas hierbas.For its part, the frame of the front part, consists of a vertical frame or column on which a carriage is vertically movable that is linked to an arm in which a plurality of string heads are established for weeding. .

Dicho brazo se adapta perfectamente a la orografía del terreno, en virtud de tres posibilidades de regulación previstos para el mismo.Said arm adapts perfectly to the orography of the terrain, by virtue of three possibilities of regulation provided for it.

• La altura del brazo se regula a partir de la altura del carro, por medio del correspondiente cilindro hidráulico. • The height of the arm is regulated from the height of the carriage, by means of the corresponding hydraulic cylinder.

• El brazo incorpora una articulación o bisagra cuya basculación se controla igualmente mediante un cilindro hidráulico y que permite no solo adaptarse a terrenos que no sean perfectamente planos y presenten una cierta inclinación con respecto a la zona por la que circula el tractor, sino también permite esquivar las plantas o árboles a cultivar, así como plegar el mecanismo para que éste ocupe un mínimo volumen cuando se transporta por carretera o es simplemente estacionado.• The arm incorporates an articulation or hinge whose tilting is also controlled by a hydraulic cylinder and which not only allows it to adapt to terrain that is not perfectly flat and has a certain inclination with respect to the area through which the tractor circulates, but also allows dodge the plants or trees to be cultivated, as well as fold the mechanism so that it occupies a minimum volume when it is transported by road or is simply parked.

• En tal sentido, se ha previsto que el brazo sea igualmente extensible lateralmente con respecto al carro al que se vincula, siendo coaxial a dicho carro y presentando un carácter telescópico que se controla a través de un tercer cilindro hidráulico.• In this sense, it has been envisaged that the arm is also laterally extensible with respect to the carriage to which it is linked, being coaxial to said carriage and presenting a telescopic character that is controlled through a third hydraulic cylinder.

De acuerdo con otra de las características de la invención, se ha previsto que en proximidad al extremo libre del brazo, éste disponga de una rueda direccionable, con objeto de que no pueda rozar el suelo y que mantenga la desbrozadora a una altura determinada.According to another of the characteristics of the invention, it has been foreseen that near the free end of the arm, it has a steerable wheel, so that it cannot rub the ground and that it maintains the brush cutter at a certain height.

También se ha previsto que en el extremo del brazo vaya instalado un sensor para evitar que el brazo de la desbrozadora pueda dañar el tronco de los árboles, del tipo de los denominados comúnmente intercepas.It has also been envisaged that a sensor is installed at the end of the arm to prevent the arm of the brushcutter from damaging the trunk of the trees, of the type commonly known as inter-vines.

Esto permite cortar la hierba exclusivamente en el espacio existente entre los troncos de la misma hilera, de manera que al detectar la presencia de un tronco el mecanismo retira hidráulicamente el brazo de la hilera de árboles para evitar dañar el troco.This makes it possible to cut the grass exclusively in the space between the logs of the same row, so that upon detecting the presence of a log, the mechanism hydraulically removes the arm from the row of trees to avoid damaging the log.

Se consigue de esta manera un dispositivo sumamente versátil, efectivo y seguro para los cultivos a desbrozar.In this way, an extremely versatile, effective and safe device is achieved for the crops to be cleared.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, puede observarse como la desbrozadora de hilo hidráulica de la invención está destinada a implantarse sobre un vehículo tractor (1), independientemente de su sistema hidráulico, en orden a evitar afectar negativamente a las prestaciones del vehículo tractor.In view of the outlined figures, it can be seen how the hydraulic wire brush cutter of the invention is intended to be installed on a towing vehicle (1), independently of its hydraulic system, in order to avoid negatively affecting the performance of the towing vehicle.

El equipo cuenta con su propia central hidráulica (15) que se dispone sobre la parte posterior del vehículo tractor a través de un bastidor posterior (16), tal como muestra la figura 2.The equipment has its own hydraulic unit (15) that is arranged on the rear of the towing vehicle through a rear frame (16), as shown in figure 2.

Paralelamente, y como se puede observar en la figura 1, sobre la parte anterior del vehículo tractor se instala un bastidor anterior (2) a modo de marco o columna vertical, sobre el que es desplazable verticalmente un carro (3) por medio de un primer cilindro hidráulico (13) alimentado por la central hidráulica (15).In parallel, and as can be seen in figure 1, a front frame (2) is installed on the front part of the towing vehicle as a frame or vertical column, on which a carriage (3) is vertically movable by means of a first hydraulic cylinder (13) fed by the hydraulic unit (15).

Al carro (3) se vincula un brazo que se divide en dos tramos relacionados entre sí por medio de una articulación o bisagra (5) asistida por un segundo cilindro hidráulico (12).An arm is linked to the carriage (3) which is divided into two interrelated sections by means of an articulation or hinge (5) assisted by a second hydraulic cylinder (12).

Así pues, se define un tramo abatible (6) para el brazo del equipo, en el que se establecen una pluralidad de motores hidráulicos (7) (al menos dos, tres en el ejemplo de realización propuesto), con un cabezal de giro (8) vinculado a una pluralidad de hilos (9) de desbrozado.Thus, a folding section (6) is defined for the arm of the equipment, in which a plurality of hydraulic motors (7) are established (at least two, three in the proposed embodiment), with a turning head ( 8) linked to a plurality of stripping threads (9).

Estos motores estarán alimentados, al igual que los diferentes cilindros hidráulicos que participan en el dispositivo, a través de conducciones hidráulicas (17) vinculadas a la central hidráulica (15) situada en la parte posterior del vehículo tractor.These motors will be powered, like the different hydraulic cylinders that participate in the device, through hydraulic lines (17) linked to the plant. hydraulic (15) located at the rear of the towing vehicle.

Por su parte, el segundo tramo (4) del brazo del mecanismo se vincula al carro (3) de forma que éste pueda desplazarse axialmente a lo largo del mismo, a modo de mecanismo telescópico accionado y controlado a través de un tercer cilindro hidráulico (11) igualmente alimentado por la centralita hidráulica (15).For its part, the second section (4) of the arm of the mechanism is linked to the carriage (3) so that it can move axially along it, as a telescopic mechanism operated and controlled through a third hydraulic cylinder ( 11) also powered by the hydraulic control unit (15).

Así pues, a partir del desplazamiento vertical del carro (3), la capacidad de abatimiento del brazo vinculado a dicho carro, así como la capacidad de extensión lateral del mismo con respecto a dicho carro (3) se consigue un mecanismo con alta capacidad de adaptación al terreno, capacidad de reducir drásticamente su volumetría, así como salvar las plantas de la zona de cultivo a tratar.Thus, from the vertical displacement of the carriage (3), the folding capacity of the arm linked to said carriage, as well as the lateral extension capacity of the same with respect to said carriage (3), a mechanism with a high capacity of adaptation to the terrain, ability to drastically reduce its volume, as well as save the plants in the growing area to be treated.

Para ello, se ha previsto que en el extremo del brazo vaya instalado un sensor para evitar que el brazo de la desbrozadora pueda dañar el tronco de los árboles, del tipo de los denominados comúnmente intercepas.To this end, a sensor is installed at the end of the arm to prevent the arm of the brushcutter from damaging the tree trunks, of the type commonly known as inter-vines.

Solo resta señalar por último que, el tramo abatible (6) del brazo incorporará en proximidad a su extremo libre, una rueda direccionable vinculada a un soporte (14), que evita que el mecanismo roce con el suelo, y garantice una separación mínima con respecto a éste. Finally, it only remains to point out that the folding section (6) of the arm will incorporate, in proximity to its free end, a steerable wheel linked to a support (14), which prevents the mechanism from rubbing with the ground, and guarantees a minimum separation with regarding this one.
