Contrapeso para vibradores de árboles frutales.Counterweight for fruit tree vibrators.

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a un contrapeso para vibradores de árboles frutales, previsto para conseguir un contrapeso de masa variable, en orden a poder adaptarse a cualquier morfología de los frutales a los que se aplica, sin dañar éstos.The present invention refers to a counterweight for fruit tree vibrators, intended to achieve a counterweight of variable mass, in order to be able to adapt to any morphology of the fruit trees to which it is applied, without damaging them.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es sabido, el funcionamiento de un vibrador de frutales, consiste en el giro, a una velocidad determinada, de un contrapeso cuya masa se encuentra desplazada del eje de giro produciendo una vibración del conjunto, el cual, al estar unido al árbol mediante almohadillas de caucho, consigue el derribo del fruto.As it is known, the operation of a fruit vibrator consists of the rotation, at a determined speed, of a counterweight whose mass is displaced from the axis of rotation, producing a vibration of the assembly, which, being attached to the tree by means of pads of rubber, achieves the demolition of the fruit.

Debido a la variopinta morfología de los árboles y las distintas variedades de los mismos, hacen que el fruto a derribar presente una mayor o menos dificultad. Si el contrapeso del vibrador es fijo, en su masa, habrá muchos casos en los que o no se produzca el derribo deseado o al ser muy brusco produzca daños en el árbol.Due to the varied morphology of the trees and the different varieties of them, they make the fruit to be felled more or less difficult. If the counterweight of the vibrator is fixed, in its mass, there will be many cases in which the desired demolition does not take place or when it is very abrupt, it damages the shaft.

Tratando de obviar esta problemática, son conocidos contrapesos que incluyen medios de regulación de su distancia frente al eje sobre el que giran, de manera que la inercia se aumente o disminuya en función de dicha distancia.Trying to obviate this problem, counterweights are known that include means for regulating their distance from the axis on which they rotate, so that the inertia increases or decreases as a function of said distance.

El problema que presentan estos contrapesos es que la regulación de los mismos resulta compleja, debido a que se encuentran insertos en el seno de una carcasa protectora, por lo que se hace preciso desmontar parcialmente la máquina, con los problemas e inconvenientes que ello supone. The problem with these counterweights is that their regulation is complex, due to the fact that they are inserted into a protective casing, which makes it necessary to partially disassemble the machine, with the problems and inconveniences that this entails.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El contrapeso para vibradores de árboles frutales que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución sencilla pero eficaz, en la que el ajuste de la inercia del contrapeso resulta sencilla y accesible.The recommended counterweight for vibrators of fruit trees solves the aforementioned problems in a fully satisfactory way, based on a simple but effective solution, in which the adjustment of the inertia of the counterweight is simple and accessible.

Para ello, la invención consiste en que la masa del contrapeso pueda variarse, y con ello adaptarse así a cualquier morfología de árbol.For this, the invention consists in that the mass of the counterweight can be varied, and thus adapt to any tree morphology.

Más concretamente, la masa del contrapeso está fijada lateralmente al correspondiente eje de giro del vibrador a modo de excéntrica, con la particularidad de que dicha masa, está afectada de una pluralidad de oquedades, realizadas por mecanizado, en las que están montadas otras tantas piezas montables/desmontables para así poder variar a voluntad la masa del conjunto y por lo tanto la inercia del eje de giro del vibrador.More specifically, the mass of the counterweight is laterally fixed to the corresponding axis of rotation of the vibrator as an eccentric, with the particularity that said mass is affected by a plurality of cavities, made by machining, in which so many other parts are mounted mountable / demountable in order to be able to vary the mass of the assembly at will and therefore the inertia of the axis of rotation of the vibrator.

Tales piezas van fijadas a la masa piezas quedan fijadas a la masa mediante anillos elásticos, siendo manipulables desde el exterior.Such pieces are fixed to the dough pieces are fixed to the dough by means of elastic rings, being manipulable from the outside.

De forma más concreta, son extraíbles mediante un tornillo roscado, a través de una abertura practicada en la cara superior de la máquina sin necesidad de realizar ningún desmontaje en su interior.More specifically, they are removable by means of a threaded screw, through an opening made in the upper face of the machine without the need for any disassembly inside.

Preferentemente, la masa en funciones de excéntrica irá fijada al eje de giro del vibrador mediante soldadura.Preferably, the eccentric-acting mass will be fixed to the axis of rotation of the vibrator by welding.

De esta forma, las maniobras de ajuste de la masa del vibrador resultan sumamente rápidas y sencillas, pudiéndose ajustar en función del grosor y tipo de árbol frutal a vibrar.In this way, the vibrator mass adjustment maneuvers are extremely fast and simple, being able to adjust depending on the thickness and type of fruit tree to vibrate.

De esta forma se puede variar la masa total del conjunto formado por la masa excéntrica (3) y las piezas (5) en función de una mayor o menor necesidad de inercia de vibración, en orden a conseguir una óptima vibración de los frutales sin dañar éstos. In this way, the total mass of the set formed by the eccentric mass (3) and the pieces (5) can be varied depending on a greater or lesser need for vibration inertia, in order to achieve optimum vibration of the fruit trees without damaging these.
