Description

Porta-útil interplantas dotado de un dispositivo limitador de esfuerzo Interplant tool holder equipped with an effort limitation device

Campo de la invención Field of the Invention

La presente invención concierne a un porta-útil para actuar entre plantas, dotado de un dispositivo limitador de esfuerzo destinado a liberar el útil cuando éste se engancha en una planta y para retornarlo a una posición de trabajo una vez se ha franqueado el citado obstáculo. The present invention concerns a tool holder for acting between plants, equipped with an effort-limiting device intended to release the tool when it is hooked on a plant and to return it to a working position once said obstacle has been overcome.

Antecedentes de la invención El estado de la técnica más próximo está descrito en la patente FR 2832203 del BACKGROUND OF THE INVENTION The closest state of the art is described in patent FR 2832203 of the

mismo solicitante que divulga un porta-útil de esta clase que comprende: un cuadrilátero articulado constituido por un primer lado transversal fijo destinado a ser unido al punto de tiro o de tracción de un tractor, un segundo lado transversal móvil, opuesto al primero, destinado a llevar el útil y dos lados longitudinales articulados, en oposición; un cilindro fluidodinámico (no representado en la citada patente) adaptado para desplazar lateralmente al útil, paralelamente a sí mismo, en el espacio existente entre dos hileras de plantas, por deformación del cuadrilátero articulado; un dispositivo limitador de esfuerzo constituido por un cilindro adaptado para desviar angularmente el útil y por un detector de esfuerzo adaptado para accionar una electroválvula de control del citado cilindro con el fin de liberar el útil cuando éste encuentra una planta y para retornarlo a una posición de trabajo una vez se ha franqueado el citado obstáculo. same applicant who discloses a tool holder of this class comprising: an articulated quadrilateral constituted by a first fixed transverse side intended to be attached to the point of pull or traction of a tractor, a second mobile transverse side, opposite the first, intended to carry the tool and two articulated longitudinal sides, in opposition; a fluid dynamic cylinder (not shown in the said patent) adapted to move the tool laterally, parallel to itself, in the space between two rows of plants, due to deformation of the articulated quadrilateral; an effort limiting device consisting of a cylinder adapted to angularly deflect the tool and a stress detector adapted to actuate a control solenoid valve of said cylinder in order to release the tool when it finds a plant and to return it to a position of work once the aforementioned obstacle has been overcome.

La utilización de un único cilindro que únicamente actúa sobre la orientación angular del útil, implica para este un recorrido espacial rotativo importante que puede alcanzar 90 0. Además se producen unos inconvenientes inherentes a unos dilatados desplazamientos, a saber: largas carreras de los cilindros y de los medios mecánicos asociados, que si el útil es de tipo vertedera tiene tendencia a trabajar según una lámina de tractor lo que repercute desfavorablemente para la calidad del trabajo efectuado, su retorno a posición de trabajo, afectando a su duración. The use of a single cylinder that only acts on the angular orientation of the tool, implies for this an important rotary spatial path that can reach 90 0. In addition there are some drawbacks inherent in large displacements, namely: long runs of the cylinders and of the associated mechanical means, that if the tool is of the dump type, it has a tendency to work according to a tractor blade, which has an unfavorable impact on the quality of the work carried out, its return to work position, affecting its duration.

Breve exposición de la invención La invención se propone realizar un dispositivo del tipo explicado, que elimina los inconvenientes anteriormente mencionados. BRIEF EXPOSURE OF THE INVENTION The invention aims to make a device of the type explained, which eliminates the aforementioned drawbacks.

A tal efecto, el detector de esfuerzo está configurado para controlar For this purpose, the stress detector is configured to control

simultáneamente: la electroválvula del cilindro limitador de esfuerzo que desvía angularmente el útil ocasionando un ligero retroceso del mismo; la electroválvula del cilindro de desplazamiento que desvía lateralmente al útil; simultaneously: the solenoid valve of the stress limiter cylinder that angularly deflects the tool causing a slight recoil of it; the solenoid valve of the displacement cylinder that laterally deflects the tool;

de manera que se combinan los dos movimientos. so that the two movements are combined.

La acción combinada de los dos cilindros hidráulicos, limitando la basculación angular del útil, hace posible su retorno automático a una posición de trabajo sin tener que detener el vehículo tractor. Además una tal configuración permite limitar la carrera del cilindro limitador de esfuerzo en más de unos 2/3. The combined action of the two hydraulic cylinders, limiting the angular tilting of the tool, makes it possible to return automatically to a working position without having to stop the towing vehicle. In addition, such a configuration allows to limit the stroke of the stress limiter cylinder by more than 2/3.

El detector de esfuerzo puede ser: de tipo apto para medir una presión hidráulica; del tipo apto para medir una presión mecánica o un desplazamiento. The stress detector can be: of a type suitable for measuring a hydraulic pressure; of the type suitable for measuring a mechanical pressure or displacement.

El cilindro limitador de esfuerzo puede estar instalado: ya sea entre un punto perteneciente al brazo del útil y un punto perteneciente al segundo lado transversal; ya sea al lugar y posición del lado longitudinal opuesto a lado longitudinal al cual está unido el primer cilindro. The stress limiter cylinder may be installed: either between a point belonging to the tool arm and a point belonging to the second transverse side; either to the place and position of the longitudinal side opposite the longitudinal side to which the first cylinder is attached.
