CAMPO DE APLICACIÓN DE LA INVENCIÓNFIELD OF APPLICATION OF THE INVENTION

El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación maquinaria agrícola, centrándose particularmente en el ámbito de las máquinas desbrozadoras, y más en particular las aplicables para el desbrozado de plantas de tipo trepadora, en particular el boniato.The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of agricultural machinery, focusing particularly on the field of brushcutting machines, and more particularly those applicable for the clearing of climbing plants, in particular sweet potato

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es sabido, el boniato es una planta de cultivo de tipo trepadora que forma una mata de tallos rastreros y ramosos con hojas acorazonadas que produce tubérculos comestibles con el mismo nombre.As is known, sweet potato is a climbing type crop plant that forms a bush of creeping and bunny stems with armored leaves that produces edible tubers with the same name.

El objetivo de la presente invención es, pues, proporcionar al mercado una máquina que facilite la labor de desbrozado de dicha planta, o de cualquier otra del mismo tipo, ya que, hasta ahora, dicha labor se efectúa manualmente o con herramientas pensadas para fines muy genéricos, pues no se conoce la existencia de ninguna máquina que esté específicamente diseñada con tal finalidad, permitiendo adaptarse a la particular forma de desarrollo de este tipo de plantas, lo cual supondría para el agricultor un importante ahorro de tiempo y, consecuentemente, de coste económico.The objective of the present invention is therefore to provide the market with a machine that facilitates the work of clearing said plant, or any other of the same type, since, until now, said work is carried out manually or with tools designed for purposes very generic, because there is no known existence of any machine that is specifically designed for this purpose, allowing to adapt to the particular form of development of this type of plants, which would mean a significant saving of time for the farmer and, consequently, of economic cost.

Como referencia al estado actual de la técnica, cabe señalar pues que, si bien existen máquinas agrícolas de muy diversa índole, al menos por parte del solicitante, se desconoce la existencia de ninguna que sea específicamente una máquina desbrozadora de plantas de cultivo trepadoras ni que presente unas características técnicas, estructurales y constitutivas iguales o semejantes a las que presenta la que aquí se reivindica.As a reference to the current state of the art, it should be noted that, although there are very diverse agricultural machines, at least on the part of the applicant, the existence of any that is specifically a brushcutter of climbing plants is not known or that present technical, structural and constitutive characteristics equal to or similar to those presented here.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La máquina desbrozadora de plantas de cultivo trepadoras que la invención propone permite alcanzar satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo hacen posible y que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción.The brushcutter of climbing plants that the invention proposes allows to satisfactorily achieve the aforementioned objectives, the characterizing details making it possible and distinguishing it conveniently collected in the final claims that accompany the present description.

En concreto, lo que la invención propone, tal como se ha apuntado anteriormente, es una máquina agrícola de funcionamiento hidráulico, la cual presenta la particularidad contar con una estructura que comprende, al menos, un mecanismo de cables giratorios que está especialmente ideado para desbrozar plantas de cultivo de tipo trepadora, en particular el boniato cuyo tallo es rastrero y ramoso, ya que el citado giro de dichos cables produce un efecto de latigazo cortante que resulta especialmente idóneo para ello al hacer pasar la máquina entre las hileras de matas de la planta del cultivo.Specifically, what the invention proposes, as noted above, is an agricultural machine of hydraulic operation, which has the particularity of having a structure comprising at least one mechanism of rotating cables that is specially designed to clear climbing plants, in particular the sweet potato whose stem is creeping and ramoso, since the aforementioned twist of these cables produces a whiplash effect that is especially suitable for doing so by passing the machine between the rows of bushes of the crop plant.

Más específicamente, el mencionado mecanismo de cables giratorios que comprende la máquina de la invención conforma un módulo formado por un eje horizontal, dispuesto en la estructura del chasis en sentido transversal respecto del movimiento de avance de la máquina a cierta altura del suelo, del que parten, radialmente y repartidos a lo largo de la extensión de dicho eje, una pluralidad de cables, o elementos filiformes similares de cierta flexibilidad y alta resistencia, preferentemente cables de acero, cuya longitud es tal que su extremo distal queda cercano al suelo o rozándolo, de tal modo que, con el desplazamiento de la máquina y el giro de dicho eje, dicha pluralidad de cables va cortando a su paso las ramas y hojas de las plantas que encuentra a su paso. More specifically, said rotating cable mechanism comprising the machine of the invention forms a module formed by a horizontal axis, arranged in the chassis structure in a transverse direction with respect to the movement of the machine at a certain height from the ground, from which split, radially and distributed along the extension of said axis, a plurality of cables, or similar filiform elements of certain flexibility and high strength, preferably steel cables, the length of which is such that its distal end is close to the ground or rubbing it , in such a way that, with the movement of the machine and the rotation of said axis, said plurality of cables is cutting in its path the branches and leaves of the plants that it finds in its path.

Cabe destacar que la longitud del descrito eje puede variar en función de las necesidades de cada caso así como que la máquina puede contar con varios módulos acoplados al chasis de la misma, preferentemente tres y no más de cinco, de manera que, con cada pasada de la máquina se desbrozan varias matas al mismo tiempo, al estar estas normalmente dispuestas en hileras paralelas. Además, uno o varios de dichos módulos pueden ser abatibles, permitiendo modificar el número de módulos a utilizar al pasar la máquina.It should be noted that the length of the described axis can vary depending on the needs of each case as well as that the machine can have several modules attached to the chassis of the same, preferably three and not more than five, so that, with each pass several bushes are cleared from the machine at the same time, since they are normally arranged in parallel rows. In addition, one or more of said modules can be foldable, allowing to modify the number of modules to be used when passing the machine.

Preferentemente, para procurar la fijación de los cables al eje de giro, este presenta una configuración cilíndrica que está estratégicamente provista de tubos perforados que, repartidos radialmente a lo largo de su superficie, emergen perpendicularmente a ella, procurando una base de fijación para el extremo proximal de los cables, los cuales se fijan en el interior de cada uno de dichos tubos, por ejemplo mediante roscado, soldado o cualquier otro sistema de anclaje, permitiendo, en su caso, la sustitución de cualquiera de ellos cuando sea necesaria.Preferably, to ensure the fixing of the cables to the axis of rotation, this presents a cylindrical configuration that is strategically provided with perforated tubes that, distributed radially along its surface, emerge perpendicularly to it, providing a fixing base for the end proximal cables, which are fixed inside each of said tubes, for example by threading, welding or any other anchoring system, allowing, where appropriate, the replacement of any of them when necessary.

Además, preferentemente, el extremo distal de los cables está provisto de un regruesamiento de refuerzo, por ejemplo determinado por la inclusión de un casquillo o similar, que evitará un excesivo o prematuro desgaste de los mismos.In addition, preferably, the distal end of the cables is provided with a reinforcement thickening, for example determined by the inclusion of a bushing or the like, which will prevent excessive or premature wear thereof.

Por otra parte, la máquina puede acoplarse a un vehículo tractor aprovechando la energía del motor del mismo para accionar el giro de los ejes, para lo cual el chasis contará con medios de acople al enganche del tractor y de conexión a su sistema hidráulico, o puede ser autónoma y estar dotada de su propio sistema hidráulico con una bomba y depósito independientes. En cualquier caso, para facilitar su desplazamiento, el chasis está provisto de ruedas y su forma y tamaño, así como el número de ruedas con que cuenta dependerá del número de módulos giratorios que comprende. Además, opcionalmente, una o varias de dichas ruedas pueden ser regulables en altura para regular la altura de actuación de los mecanismos de cables giratorios.On the other hand, the machine can be coupled to a tractor vehicle taking advantage of the engine's power to drive the rotation of the axles, for which the chassis will have means of coupling to the tractor hitch and connection to its hydraulic system, or It can be autonomous and equipped with its own hydraulic system with an independent pump and tank. In any case, to facilitate its displacement, the chassis is provided with wheels and its shape and size, as well as the number of wheels it has will depend on the number of rotating modules it comprises. In addition, optionally, one or more of said wheels can be height adjustable to regulate the operating height of the rotating cable mechanisms.

Por ejemplo, en una forma de realización, la estructura que constituye el chasis de la máquina tiene una configuración en forma de cerco rectangular, en cuyo centro se disponen tres módulos de cables giratorios, cada uno de ellos acoplado de modo independiente al perfil posterior que conforma dicho cerco del chasis.For example, in one embodiment, the structure that constitutes the chassis of the machine has a configuration in the form of a rectangular fence, in whose center three modules of rotating cables are arranged, each of them coupled independently of the rear profile that conforms said frame of the chassis.

Preferentemente, además, cada módulo está dotado de sendos discos laterales, que tienen un diámetro similar al que abarcan los cables emergiendo radialmente del eje giratorio, y que tiene una doble función de corte y de protección de los cables y salpicaduras del desbroce, así como y de una carcasa superior que, con una configuración semicircular, cubre aproximadamente la mitad superior del espacio circular que abarcan dichos cables, sirviendo de protección, para evitar cualquier riesgo ante el movimiento giratorio de los cables, y como pantalla para frenar la dispersión de los restos vegetales desbrozados.Preferably, in addition, each module is provided with two side disks, which have a diameter similar to that covered by the cables emerging radially from the rotating shaft, and having a double function of cutting and protecting the cables and splashing of the clearing, as well as of an upper housing that, with a semicircular configuration, covers approximately the upper half of the circular space covered by said cables, serving as protection, to avoid any risk against the rotating movement of the cables, and as a screen to stop the dispersion of the cleared plant remains.
