Abstract

uma broca de rocha e um conjunto de perfuração para perfuração de rocha por percussão. a invenção se refere a uma broca de rocha (30) para perfuração de percussão compreende uma cabeça de broca configurada para ser ligada a uma extremidade de um elemento de perfuração (33) de um conjunto de perfuração, e que tem um diâmetro maior do que o do dito furo. a cabeça de broca tem, em uma extremidade frontal (38), vista na direção pretendida de perfuração, uma pluralidade de botões (41) distribuída ao longo da dita cabeça de broca e disposta para engatar com um material a ser triturado. pelo menos um dos ditos botões é livre para girar em torno do seu próprio eixo de simetria.a rock drill and a drill set for percussion rock drilling. The invention relates to a rock drill bit (30) for percussion drilling comprising a drill head configured to be connected to one end of a drill member (33) of a drill assembly, and having a diameter greater than that of said hole. the drill head has, at one front end (38), viewed in the intended drilling direction, a plurality of knobs (41) distributed along said drill head and arranged to engage with a material to be ground. At least one of said buttons is free to rotate about its own axis of symmetry.
