DESCRIPCIONDESCRIPTION
Desbrozadora para cultivos de riego por goteo.Brushcutter for drip irrigation crops.
Sector de la tecnicaTechnology Sector
La presente invencion pertenece al sector del equipamiento agricola y mas concretamente al de los dispositivos para el control de hierbas y malezas en los cultivos de riego por goteo.The present invention belongs to the agricultural equipment sector and more specifically to the devices for weed and weed control in drip irrigation crops.
El objeto de la presente invencion es una desbrozadora de hierbas con elemento cortante flexible, cuya principal ventaja es poderla acoplar a un vehlculo tractor mediante un brazo articulado y de forma comoda y segura eliminar hierbas de los cultivos sin danar la tuberla de goteo, de forma que se pueda mecanizar la labor.The object of the present invention is a weed brushcutter with flexible cutting element, whose main advantage is to be able to attach to a tractor vehicle by means of an articulated arm and in a comfortable and safe way to remove herbs from the crops without damaging the drip pipe, so that the work can be mechanized.
Esta compuesta de varios cabezales o elementos de corte, con varias anchuras de trabajo dependiendo del numero de cabezales que se le instalen, para trabajar en la zona de influencia de los goteros, que es donde mas hierbas y malezas indeseables aparecen en estos cultivos y gracias al elemento de corte flexible evita danar la tuberla de goteros de riego que suele estar colocada en la superficie, no enterrada y que suele ser de material plastico, siendo vulnerable dicha tuberla a las otras desbrozadoras agricolas existentes que tienen elementos de corte metalicos.It is composed of several heads or cutting elements, with several working widths depending on the number of heads that are installed, to work in the area of influence of the drippers, which is where more undesirable weeds and weeds appear in these crops and thanks The flexible cutting element avoids damaging the pipe of irrigation drippers that is usually placed on the surface, not buried and that is usually made of plastic material, said pipe being vulnerable to the other existing agricultural brushcutters that have metal cutting elements.
La hierba puede quedar cortada en trozos muy pequenos encima de la zona humeda del riego por goteo, formando una alfombra vegetal, eliminando en gran parte la evaporation y por tanto consiguiendo un importante ahorro de agua e incrementando la riqueza en materia organica del suelo, muy beneficiosa para el cultivo.The grass can be cut into very small pieces on top of the wet area of drip irrigation, forming a vegetal carpet, largely eliminating evaporation and therefore achieving significant water savings and increasing the richness of organic soil, very Beneficial for cultivation.
Para ello los cabezales giran a gran velocidad, entre 5.000 y 15.000 rpm para que el elemento cortante de plastico cumpla con su cometido.For this, the heads rotate at high speed, between 5,000 and 15,000 rpm so that the plastic cutting element fulfills its task.
La maquina va acoplada al tractor mediante un brazo articulado de accionamiento hidraulico que puede ser manipulado por el tractorista con gran precision para adaptarla al terreno e incluso a los caballones del cultivo.The machine is coupled to the tractor by means of an articulated arm of hydraulic drive that can be manipulated by the tractor with great precision to adapt it to the ground and even to the crop's ridges.
Antecedentes de la invencionBackground of the invention
En los cultivos con riego por goteo, que son los mas productivos y los de mayor eficiencia de aprovechamiento del agua de riego, aparecen gran cantidad de hierbas en la zona de influencia de los goteros debido a que en la mayorla de ellos se aplica el fertilizante disuelto con el agua.In crops with drip irrigation, which are the most productive and the most efficient use of irrigation water, a large number of herbs appear in the area of influence of the drippers because in most of them the fertilizer is applied dissolved with water.
Estas hierbas, cuando crecen y adquieren un considerable tamano, consumen gran cantidad de agua y fertilizantes destinados al cultivo, por lo que compiten directamente con el, provocando perjuicios economicos muy importantes al agricultor, de ahl la importancia de controlarlas.These herbs, when they grow and acquire a considerable size, consume a large amount of water and fertilizers intended for cultivation, so they compete directly with it, causing very important economic damage to the farmer, hence the importance of controlling them.
Dado que hasta ahora las desbrozadoras mecanicas que se utilizan en los cultivos estan equipadas con elementos cortantes metalicos, estas suelen danar la tuberla de goteros de riego y solo son utilizadas en las calles por lo que para la eliminacion de las hierbas enSince until now the mechanical brushcutters that are used in the crops are equipped with metal cutting elements, these usually damage the pipe of irrigation drippers and are only used in the streets so that for the elimination of herbs in

las llneas de cultivo se suelen utilizar herbicidas, sustancias qulmicas que mediante diversas formas de actuacion eliminan las hierbas que compiten con el cultivo.The cultivation lines are usually used herbicides, chemical substances that, through various forms of action, eliminate the herbs that compete with the crop.
Estos herbicidas suelen ser toxicos en cierta medida para el cultivo, para la fauna util del entorno y para el ser humano. El herbicida mas utilizado en la actualidad es Glifosato que, segun la Organization Mundial de la Salud, en su informe "IARC Monographs Volume 112: evaluation of five organophosphate insecticidas and herbicidas-, de 20 de Marzo de 2015, considera: que en el herbicida glifosato, hay pruebas limitadas de carcinogenicidad en humanos para el linfoma no Hodgkin". Por esta razon, la OMS lo ha catalogado como "probable carcinogeno" y a corto-medio plazo posiblemente estaran prohibidos este y muchos otros herbicidas y se eliminaran del mercado para su uso en los cultivos. De ahl el interes de esta maquina como alternativa para el control de hierbas a la utilization de herbicidas qulmicos.These herbicides are usually toxic to some extent for the crop, for the useful fauna of the environment and for the human being. The herbicide most used today is Glyphosate which, according to the World Health Organization, in its report "IARC Monographs Volume 112: evaluation of five organophosphate insecticides and herbicides-, of March 20, 2015, considers: that in the herbicide glyphosate, there is limited evidence of human carcinogenicity for non-Hodgkin lymphoma. " For this reason, WHO has listed it as "probable carcinogen" and in the short-medium term this and many other herbicides may be banned and removed from the market for use in crops. Hence the interest of this machine as an alternative for the control of herbs to the use of chemical herbicides.
Por otro lado es reconocido en diversos informes cientlficos y contrastado con numerosas experiencias, que la cubierta vegetal controlada, manteniendo la hierba espontanea del cultivo desbrozada a una altura que no ejerza competencia a las plantas cultivadas, es mucho mas beneficiosa para el cultivo, para el suelo que lo sustenta y para la biodiversidad, que eliminar la hierba totalmente con herbicidas o con la labranza tradicional.On the other hand it is recognized in various scientific reports and contrasted with numerous experiences, that the controlled vegetation cover, keeping the spontaneous grass of the crop cleared at a height that does not exercise competition to the cultivated plants, is much more beneficial for the crop, for the soil that sustains it and for biodiversity, that eliminate the herb entirely with herbicides or traditional tillage.
As! mismo, en agricultura ecologica certificada no esta permitido la utilizacion de herbicidas para el control de hierbas, por lo que este invento es de gran utilidad para dicho control y el correcto desarrollo de los cultivos.Ace! In certified organic farming, the use of herbicides for the control of herbs is not allowed, so this invention is very useful for such control and the correct development of crops.
Como hemos mencionado, existen desbrozadoras agricolas para el control de hierbas en las calles de los cultivos con diversas anchuras de trabajo pero con elementos cortantes rlgidos, normalmente metalicos o de cadenas, como la "Desbrozadora de Cubiertas Vegetales" (ES 1 147 958 U) con cinco cabezales en llnea materializados en acero con un gran ancho de trabajo, el "Sistema Desbrozador para Margenes Viales con Obstaculos y Otros" (ES2534703 A 1) con cuchillas metalicas rlgidas con brazo articulado que corta entamo a obstaculos, orientadas al desbrozado en margenes de carreteras, la "Desbrozadora Polivalente Perfeccionada" (ES 1 045 650 U) constituida por un cilindro con cadenas que en su normal funcionamiento no respetan las tuberlas de riego por goteo.As we have mentioned, there are agricultural brushcutters for the control of herbs on the streets of crops with various working widths but with rigid cutting elements, usually metal or chains, such as the "Vegetable Cover Brushcutter" (ES 1 147 958 U) with five in-line heads materialized in steel with a large working width, the "Clearing System for Road Margins with Obstacles and Others" (ES2534703 A 1) with rigid metal blades with articulated arm that cuts into obstacles, oriented to the clearing in margins of roads, the "Improved Multi-purpose Brushcutter" (ES 1 045 650 U) constituted by a cylinder with chains that in their normal operation do not respect the drip irrigation pipes.
Existe alguna otra como la "Maquina desbrozadora perfeccionada" (ES1064235U) con elemento de corte flexible, montada en un tractor, pero con accionamiento electrico y que consta de un solo cabezal, para eliminar malezas de terrenos, margenes de caminos y carreteras.There is some other such as the "Improved Brushcutter" (ES1064235U) with flexible cutting element, mounted on a tractor, but with electric drive and consisting of a single head, to eliminate weeds from land, road and road margins.
Tambien existen en la actualidad dispositivos de desbroce con elementos cortantes flexibles, como son los "Recortadores de Vegetation" (ES2302138 T3), el "Cabezal de corte de Hilo..." (ES 2 559 364 T3) o la "Desbrozadora" (ES 2 382 134 T3), pero estos estan disenados para ser usados en trabajos de desbroce, principalmente de jardinerla, en los que la persona que los maneja va a pie y nunca se han ideado para que, trabajando con varios cabezales de corte de forma simultanea y con gran anchura de corte, se pueda mecanizar y acoplar a un vehlculo tractor para obtener un rendimiento industrial, con una anchura de trabajo suficiente para el control de hierbas en fincas agricolas de cultivos con riego por goteo.There are also currently clearing devices with flexible cutting elements, such as the "Vegetation Trimmers" (ES2302138 T3), the "Thread cutting head ..." (ES 2 559 364 T3) or the "Brushcutter" ( EN 2 382 134 T3), but these are designed to be used in clearing works, mainly gardening, in which the person who handles them goes on foot and they have never been designed so that, working with several cutting heads Simultaneously and with great cutting width, a tractor vehicle can be machined and coupled to obtain industrial performance, with a sufficient working width for the control of herbs in agricultural farms of crops with drip irrigation.

Ninguna de las invenciones relacionadas anteriormente pueden solucionar de forma mecanizada con un rendimiento industrial el problema grave que tienen los cultivos con riego por goteo de poder controlar las hierbas que surgen en la zona humeda del cultivo sin perjudicar a la propia tuberla de riego que se encuentra en la superficie del terreno.None of the inventions related above can mechanically solve with industrial performance the serious problem that crops with drip irrigation have to be able to control the herbs that arise in the humid area of the crop without harming the irrigation pipe itself on the ground surface.
Explicacion de la invencionExplanation of the invention
El problema tecnico que resuelve la presente invencion es conseguir una desbrozadora de aplicacion industrial en la agricultura, que corte a una altura deseada la hierba que surge en la zona de influencia del riego por goteo de los cultivos, sin que el elemento cortante perjudique la tuberla plastica de riego que discurre por la superficie del terreno, de forma que se controle la mencionada hierba y deje de ser perjudicial para el cultivo sin necesidad de aplicar herbicidas qulmicos.The technical problem solved by the present invention is to achieve an industrial brushcutter in agriculture, which cuts at a desired height the grass that arises in the area of influence of the drip irrigation of crops, without the cutting element damaging the pipe irrigation plastic that runs along the surface of the land, so that the above-mentioned grass is controlled and ceases to be harmful to the crop without the need to apply chemical herbicides.
Para ello, esta desbrozadora contara con un bastidor que soporta varios cabezales de corte cuyos elementos cortantes son hilos flexibles fabricados con material plastico sintetico que giran a gran velocidad, entre 5.000 y 15.000 rpm accionados por un motor hidraulico que transmite el movimiento a los cabezales por medio de correas dentadas y poleas y al que le suministra la energla el vehlculo tractor que soporta dicho bastidor.For this, this brush cutter will have a frame that supports several cutting heads whose cutting elements are flexible threads made of synthetic plastic material that rotate at high speed, between 5,000 and 15,000 rpm driven by a hydraulic motor that transmits the movement to the heads by means of toothed belts and pulleys and to which the tractor vehicle that supports said frame is energized.
Los cabezales estaran colocados al tresbolillo de forma que se solapen su anchura de trabajo con el cabezal anterior o posterior para que no quede zona sin desbrozar en toda la anchura de trabajo de la maquina.The heads will be placed to the tresbolillo so that their working width overlaps with the front or rear head so that there is no area without clearing the entire working width of the machine.
Opcionalmente tendra un cabezal de corte adicional montado en un brazo exterior que extendera el ancho de trabajo hacia fuera de la zona del bastidor para cortar la hierba de la zona entre los troncos de los arboles y que sera retractil, de forma que cuando se aproxime a los troncos, se retrotraera hacia la parte posterior del bastidor de la maquina, evitando as! danar al cultivo.Optionally you will have an additional cutting head mounted on an outer arm that will extend the working width out of the area of the frame to cut the grass from the area between the trunks of the trees and that will be retractable, so that when it approaches the trunks, will roll back towards the back of the machine frame, thus avoiding! damage the crop.
El bastidor dispondra de unos patines para mantener la altura de trabajo deseada y por tanto la altura de corte de la hierba que se decida. A su vez estos patines evitaran que los cabezales se deterioren ya que impiden que estos entren en contacto con la tierra.The frame will have skates to maintain the desired working height and therefore the cutting height of the grass that is decided. In turn, these skates will prevent the heads from deteriorating as they prevent them from coming into contact with the ground.
El bastidor tendra unas tapas protectoras que eviten el lanzamiento de piedras u objetos del terreno hacia el exterior de la maquina, de forma que se eviten accidentes a los trabajadores, danos en el vehlculo tractor o lesiones a los troncos del cultivo. La tapa posterior sera basculante y adecuada para facilitar la salida de la hierba cortada.The frame will have protective covers that prevent the throwing of stones or objects from the ground towards the outside of the machine, so as to avoid accidents to workers, damage to the tractor vehicle or injuries to the trunks of the crop. The back cover will be tilting and adequate to facilitate the exit of the cut grass.
La maquina dispondra de una placa soporte anclada adecuadamente para poder acoplarla al tractor mediante un brazo articulado que la adapte al terreno a eleccion del operario segun su topografla.The machine will have a support plate anchored properly to be able to attach it to the tractor by means of an articulated arm that adapts it to the terrain chosen by the operator according to its topography.
