Description

Mejoras introducidas en la patente de invención nº P 200601852 por: "Máquina prepodadora articulada de discos de corte".Improvements introduced in the invention patent No. P 200601852 by: "Articulated disk pre-mower machine cut".

Objeto de la invenciónObject of the invention

La presente invención propone una serie de mejoras en la máquina prepodadora de discos de corte objeto de la patente de invención 200601852, la cual se fija preferentemente al frontal de un tractor y se emplea para los trabajos, tanto de prepoda, como de descarga de ramaje en frutales y olivares.The present invention proposes a series of improvements in the pre-pruner cutting discs machine object of the invention patent 200601852, which is preferably fixed to the front of a tractor and is used for jobs, both of prepoda, as a branch discharge in fruit trees and olive groves.

Uno de los objetivos de la invención consiste en definir una estructura articulada entre el mástil central de la máquina y el brazo extremo que monta los discos de corte, de tal modo que para un sentido de desplazamiento del tractor entre hileras de árboles se pueda efectuar tanto el corte vertical como el corte horizontal en el mismo lado de una hilera de árboles, de tal modo que el corte horizontal no produzca acumulaciones de restos de poda sobre los árboles.One of the objectives of the invention is to define an articulated structure between the central mast of the machine and the end arm that mounts the cutting discs, such so that for a direction of travel of the tractor between rows of trees you can make both vertical cutting and cutting horizontal on the same side of a row of trees, thereby that the horizontal cut does not produce accumulations of pruning remains Over the trees

Otro de los objetivos de la invención se refiere a la optimización de los medios empleados para la motorización y transmisión del movimiento de los discos cortantes.Another object of the invention relates to to the optimization of the means used for motorization and transmission of the movement of the cutting discs.

Antecedentes de la invenciónBackground of the invention

La máquina prepodadora articulada de discos de corte que describe la solicitud de patente de invención 200601852 se aplica sobre el frontal de un tractor mediante un bastidor y consta fundamentalmente de un mástil que articula centrado respecto al bastidor en un primer plano vertical y está asociado a un brazo extremo que monta los discos de corte con interposición de un brazo intermedio.The articulated disk pre-molding machine court describing the patent application for invention 200601852 se applied on the front of a tractor using a frame and consists fundamentally of a mast that articulates centered with respect to the frame in a vertical foreground and is associated with an arm end that mounts the cutting discs with interposition of an arm intermediate.

El mástil es desplazable telescópicamente y está vinculado por su extremidad superior a una cartela doble, con intermediación de un perfil de unión, respecto a la que articula el brazo intermedio en un segundo plano vertical y paralelo al primer plano vertical. El brazo extremo que porta los discos de corte está articulado en su zona media respecto al brazo intermedio para girar en este segundo plano vertical o en un plano perpendicular a éste, pudiendo adoptar dicho brazo extremo distintas inclinaciones de corte.The mast is telescopically movable and is linked by its upper extremity to a double cartouche, with intermediation of a joint profile, with respect to which articulates the intermediate arm in a vertical background parallel to the first vertical plane The end arm that carries the cutting discs is articulated in its middle area with respect to the intermediate arm to rotate in this second vertical plane or in a plane perpendicular to it, said end arm being able to adopt different inclinations of cut.

La posición de los distintos brazos se regula mediante una serie de cilindros hidráulicos determinando el posicionamiento final de los discos de corte, bien en posición vertical para efectuar el corte vertical de los árboles por un lado de la hilera o bien en posición horizontal para efectuar el corte horizontal de la copa de los árboles.The position of the different arms is regulated through a series of hydraulic cylinders determining the final positioning of the cutting discs, either in position vertical to effect vertical cutting of trees on one side of the row or horizontally to make the cut Treetop horizontal.

De acuerdo con la estructura de la máquina prepodadora, durante el desplazamiento del tractor en un sentido se puede efectuar el corte vertical de un lado de una hilera de árboles con el brazo extremo situado en posición vertical, y se puede cambiar la posición de dicho brazo extremo, tras basculación del mástil, hasta adoptar una posición horizontal en la que puede efectuar el corte horizontal de las copas de los árboles situados en la hilera paralela a la anterior.According to the structure of the machine pre-pruner, while moving the tractor in one direction it can make the vertical cutting of one side of a row of trees with the extreme arm located in an upright position, and you can change the position of said end arm, after tilting the mast, until you adopt a horizontal position where you can make the horizontal cut of the treetops located in the row parallel to the previous one.

Durante el corte vertical el sentido de giro de las cuchillas de corte determina que las ramas o trozos cortados caigan hacia delante y hacia abajo. Al pasar el brazo extremo desde su posición vertical en la que corta lateralmente una hilera de árboles a su posición horizontal en la que corta la hilera paralela, se mantiene el mismo sentido de giro de las cuchillas de corte. Las cuchillas por tanto en su corte horizontal determinan que las ramas cortadas se dirijan hacia el exterior del tractor, acumulándose en los lados no podados de las zonas superiores de los árboles. Esta situación se da especialmente cuando los árboles superan una altura concreta, del orden de dos metros y medio.During vertical cutting the direction of rotation of the cutting blades determines that the branches or pieces cut Fall forward and down. When passing the extreme arm from its vertical position where it cuts laterally a row of trees to their horizontal position where they cut the parallel row, the same direction of rotation of the cutting blades is maintained. The blades therefore in their horizontal cut determine that the branches cut off to the outside of the tractor, accumulating in the pruned sides of the upper areas of the trees. This situation occurs especially when trees exceed a height concrete, of the order of two and a half meters.

Esta acumulación de trozos o de ramas cortadas en las zonas superiores no podadas traen como consecuencia que al podar estas zonas por el lado contrario las cuchillas se emboten o atasquen al encontrar los trozos previamente cortados.This accumulation of pieces or cut branches in the upper areas not pruned bring as a consequence that prune these areas on the opposite side the blades become dull or jam when you find the previously cut pieces.

Por otra parte en lo que se refiere al sistema de corte que se muestra en dicho documento, éste está compuesto por una transmisión de giro mediante poleas. La potencia de giro en el corte la suministra un único motor hidráulico acoplado directamente a un disco central. La transmisión a los otros discos se realiza mediante dos correas por cada polea, por lo que cada polea posee cuatro canales. El conjunto formado por motor y disco central son fijos al chasis y los conjuntos formados por eje, polea y disco de los laterales disponen unas guías correderas que permiten el correcto tensado de las correas de transmisión. En este caso al disponer de un único motor central se obtienen muchas pérdidas en las poleas del extremo, y para obtener la potencia requerida en éstas se puede llegar a producir un problema de rotura de las correas intermedias.On the other hand as regards the system of cut that is shown in this document, this one is composed by a turn transmission by pulleys. The turning power in the cutting is supplied by a single hydraulic motor directly coupled to a central disk. The transmission to the other discs is done by two belts for each pulley, so each pulley has Four channels The set consisting of motor and central disk are fixed to the chassis and the assemblies formed by shaft, pulley and disc of the sides have sliding guides that allow correct tensioning of the transmission belts. In this case at having a single central engine many losses are obtained in the end pulleys, and to obtain the required power in these can lead to a problem of breakage of the intermediate straps.

Otras soluciones contemplan la incorporación de un motor por cada disco de corte que resuelve los problemas de potencia de corte, pero por otra parte se produce un excesivo calentamiento del aceite al hacer pasar el suministro por todos los motores cuando estos están conectados en serie. Asimismo la conexión en serie de tantos motores puede llegar a producir la rotura de los retenes que los conectan por sobrepresión.Other solutions include the incorporation of one motor for each cutting disc that solves the problems of cutting power, but on the other hand there is excessive oil heating by passing the supply through all motors when these are connected in series. Also the connection In series of so many engines can produce the breakage of the seals that connect them by overpressure.

Descripción de la invenciónDescription of the invention

Una de las mejoras que propone esta invención se refiere a la adopción de una estructura con forma de paralelogramo que conecta el mástil con el brazo que porta los discos de corte, de tal forma dispuesta y configurada, que permite llevar a cabo cortes, tanto verticales como horizontales, en el mismo lado del tractor, con los discos de corte girando en el mismo sentido, de modo tal que el corte vertical dirija las ramas cortadas hacia abajo y el corte horizontal dirija las ramas cortadas hacia afuera del árbol, evitando así la acumulación de restos de poda en la zona superior de los árboles. De esta manera se evita que al pasar la máquina por el lado contrario para efectuar el corte completo, pueda encontrarse con restos de corte acumulados que entorpezcan la labor de corte de la máquina.One of the improvements proposed by this invention is refers to the adoption of a parallelogram-shaped structure which connects the mast with the arm that carries the cutting discs, of such an arranged and configured form, which allows to carry out cuts, both vertical and horizontal, on the same side of the tractor, with the cutting discs rotating in the same direction, so that the vertical cut direct the cut branches down and the cut horizontal direct the cut branches out of the tree, thus avoiding the accumulation of pruning remains in the upper area of the trees This prevents the machine from passing through the machine. opposite side to make the complete cut, can be found with accumulated cutting remains that hinder the work of cutting machine.

El mástil articula por un punto respecto al bastidor y es de tipo telescópico dotado de un cuerpo tubular hembra que articula sobre el bastidor y de un cuerpo tubular macho que desplaza telescópicamente respecto al cuerpo hembra que está finalizado en la estructura de paralelogramo antes descrita, situada en el mismo primer plano vertical en el que gira el mástil articulado. La estructura está formada por una primera cartela a la que se encuentran articulados un tensor superior y un brazo inferior a su vez articulados a una segunda cartela, respecto a la que puede girar a su vez el brazo extremo que porta los discos de corte en un segundo plano paralelo al primero.The mast articulates by a point with respect to the frame and is telescopic type equipped with a female tubular body which articulates on the frame and a male tubular body that telescopically shifts relative to the female body that is completed in the parallelogram structure described above, located in the same vertical foreground where the mast rotates articulate. The structure is formed by a first cartouche to the that an upper tensioner and a lower arm are articulated in turn articulated to a second cartouche, with respect to which you can turn the end arm that carries the cutting discs in a background parallel to the first.

El cuerpo hembra del mástil está asociado al bastidor mediante un primer cilindro que permite el movimiento giratorio de dicho cuerpo hembra para fijar la inclinación del mástil, por otro lado el movimiento telescópico del cuerpo macho se ocasiona mediante un segundo cilindro que determina la extensión en altura del mástil.The female body of the mast is associated with frame using a first cylinder that allows movement rotating said female body to set the inclination of the mast, on the other hand the telescopic movement of the male body is caused by a second cylinder that determines the extent in mast height

Por otra lado el brazo inferior es actuado por un tercer cilindro montado sobre la primera cartela para ocasionar su giro en el mismo plano vertical en el que gira el mástil, el cual determina solidariamente el giro del tirante y a su vez de la segunda cartela que arrastra el brazo extremo que porta los discos de corte.On the other hand the lower arm is operated by a third cylinder mounted on the first bracket to cause its rotation in the same vertical plane in which the mast rotates, which jointly determines the turn of the strap and in turn of the second card dragging the end arm that carries the discs cutting

Entre la segunda cartela y el brazo extremo se dispone asimismo un cuarto cilindro que facilita el giro del brazo extremo respecto a dicha segunda cartela en el segundo plano vertical paralelo al primero.Between the second cartouche and the extreme arm is It also has a fourth cylinder that facilitates the rotation of the arm extreme with respect to said second cartouche in the background vertical parallel to the first.

Es de destacar asimismo que mediante esta máquina se consigue que en el corte horizontal, al despedir los restos hacia fuera, éstos no queden atrapados en el interior del ramaje del árbol, evitando el trabajo de retirar dichos restos a mano.It is also noteworthy that through this machine you get that in the horizontal cut, by firing the remains out, these are not trapped inside the tree branch, avoiding the work of removing these remains hand.

Otra de las mejoras que propone esta invención se refiere a la incorporación en el brazo extremo de dos motores hidráulicos, asociados a respectivos discos de corte, de menor potencia que el motor hidráulico citado en la patente original, que se encuentran conectados en serie disminuyendo así el caudal hidráulico del circuito, así como las pérdidas por rozamiento y los problemas de calentamiento. Los diferentes discos de corte están vinculados a correspondientes poleas que se encuentran relacionadas entre sí mediante correas de transmisión de acuerdo con una solución de montaje en la que las correas están sometidas a menos tensiones, redundando consecuentemente en un aumento de vida de las mismas.Another improvement proposed by this invention refers to the incorporation in the end arm of two engines hydraulic, associated to respective cutting discs, smaller power than the hydraulic motor cited in the original patent, which they are connected in series thus reducing the flow hydraulic circuit, as well as friction losses and heating problems The different cutting discs are linked to corresponding pulleys that are related each other by transmission belts according to a solution of assembly in which the belts are subject to less stress, consequently resulting in an increase in their life.

El disco de corte central se encuentra montado con su polea en posición fija sobre el brazo extremo, mientras que el resto de los discos de corte están situados a ambos lados de éste, encontrándose montados con facultad de desplazamiento sobre dicho brazo extremo con posibilidad de regular la distancia entre ellos y respecto al disco de corte central, facilitando de esta manera la regulación de la tensión de las correas de transmisión que relacionan las poleas. Los motores se montan sobre respectivas poleas, que están dispuestas a ambos lados del disco central.The central cutting disc is mounted with its pulley in a fixed position on the extreme arm while the rest of the cutting discs are located on both sides of this one, being mounted with faculty of displacement on said extreme arm with the possibility of regulating the distance between them and with respect to the central cutting disc, facilitating this way the tension regulation of the transmission belts that They relate the pulleys. The engines are mounted on respective pulleys, which are arranged on both sides of the central disk.

Al encontrarse todas las poleas conectadas en serie se consigue que en los casos en los que solamente trabajan dos discos de corte situados en un extremo, éstos necesitan toda la potencia hidráulica de corte, por lo que la polea central que comunica las poleas motrices absorbe la potencia del motor que trabaja en vacío y se la presta a las poleas que están trabajando puntualmente.When all the pulleys are connected in series is achieved in cases where only two work cutting discs located at one end, these need all the hydraulic cutting power, so the central pulley that communicates the driving pulleys absorbs the engine power that works in a vacuum and lends it to the pulleys that are working promptly.
