Más precisamente, el vástago oscilante soporta sobre el extremo libre un ancho apto para actuar en asido sobre la rama del árbol a someter a sacudidas. El gancho está usualmente conformado en "U" con los dos brazos que están provistos de vainas cilíndricas, estas últimas generalmente de goma.As is known, in order to effect an effective Tree shake for the collection of olives, nuts, hazelnuts, fruits and the like devices are generally used portable shakers powered by a motor group which drives in oscillation, through an eccentric, a shaker rod that the operator directs and positions so that it transmits the oscillation to Tree branches to shake. More precisely, the stem oscillating supports a width suitable for acting on the free end in hold on the tree branch to shake. The hook is usually "U" shaped with both arms that are provided with cylindrical sheaths, the latter generally of rubber.
Operativamente, la rama a sacudir es insertada en la cavidad entre las dos vainas y, a través de un mando manual común, el operario puede accionar el movimiento oscilante del vástago y por tanto determinar la caída de los frutos, por ejemplo, aceitunas.Operationally, the branch to shake is inserted in the cavity between the two pods and, through a manual control common, the operator can activate the oscillating movement of the stem and therefore determine the fall of the fruits, for example, olives
La rama, durante la acción oscilante impartida por el vástago del dispositivo realiza un movimiento relativo en el interior de la cavidad de acoplamiento del gancho determinado fuertes rozamientos, acciones abrasivas y choques contra las superficies cilíndricas de las dos vainas.The branch, during the oscillating action imparted by the rod of the device performs a relative movement in the inside of the coupling hook cavity determined strong friction, abrasive actions and shocks against cylindrical surfaces of the two sheaths.
Por este motivo, las dos vainas que están en contacto directo con la rama resultan sometidas a acciones de desgaste debidas a la abrasión causada sobre todo por el sobrecalentamiento que se genera en los puntos de contacto entre las superficies de las vainas y las ramas.For this reason, the two pods that are in direct contact with the branch are subject to actions of wear due to abrasion caused mainly by the overheating that is generated at the contact points between the pod surfaces and branches.
Además, se ha observado que los fuertes rozamientos entre las vainas y la rama sometida a sacudidas pueden perjudicar irremediablemente esta última, sobre todo cuando cada vaina presenta la típica acanaladura transversal respecto al eje de la vaina, la cual resulta siempre más marcada con el tiempo.In addition, it has been observed that the strong friction between the sheaths and the shaken branch may irretrievably harm the latter, especially when each sheath presents the typical transverse groove relative to the axis of the pod, which is always more marked with time.
Se hace, por tanto, necesario sustituir frecuentemente las vainas.It is therefore necessary to replace Frequently the pods.
Resulta, por tanto, muy sentida la exigencia de tener a disposición un elemento de asido para dispositivos sacudidores de árboles que sea capaz de reducir sensiblemente las acciones de rozamiento y de abrasión reciproca entre las vainas y la rama típicas de las soluciones de la técnica conocida.Therefore, the demand for have available a gripping element for devices tree shakers that are capable of significantly reducing the friction and reciprocal abrasion actions between the pods and The typical branch of the known technique solutions.
