Abstract

DEDO DE ESCAVAÇÃO E BALDE DE ESCAVAÇÃO ASSOCIADO. A presente invenção refere-se a um dedo de escavação (132) de uma caçamba (130) que é projetado para ser encaixado em uma corrente de escavação (8) para um dispositivo (4) de escavação de lastro sob uma ferrovia (2), o dedo (132) sendo em uma peça e compreendendo: uma porção de retenção (132b) que é rotacionalmente simétrica em torno de um eixo de referência (X) do dedo (132), a porção de retenção (132b) sendo projetada para ser acomodada em uma cavidade cilíndrica (134) da caçamba (130); e uma ponta (132a) criada para se projetar para fora da cavidade cilíndrica (134) da caçamba (130), sendo o dedo de escavação (132) caracterizado pelo fato de que a porção de retenção (132b) compreende pelo menos um canal anular (132c) que é configurado para receber pelo menos parte de uma haste de imobilização (135), projetada para fornecer retenção axial da porção de retenção (132b) na cavidade cilíndrica (134) de tal forma que o dedo (132) esteja livre para girar em torno de seu eixo de referência (X).EXCAVING FINGER AND ASSOCIATED EXCAVING BUCKET. The present invention relates to a digging finger (132) of a bucket (130) which is designed to be fitted to an digging chain (8) for a ballast digging device (4) under a railroad track (2) , the finger (132) being in one piece and comprising: a retaining portion (132b) which is rotationally symmetric about a reference axis (X) of the finger (132), the retaining portion (132b) being designed to be accommodated in a cylindrical cavity (134) of the bucket (130); and a tip (132a) created to project out of the cylindrical cavity (134) of the bucket (130), the digging finger (132) being characterized in that the retaining portion (132b) comprises at least one annular channel (132c) which is configured to receive at least part of an immobilization rod (135) designed to provide axial retention of the retention portion (132b) in the cylindrical cavity (134) such that the finger (132) is free to rotate around its reference axis (X).
