Abstract

Conjunto de ponteira para máquinas de movimentação de terra. Onde a invenção refere-se a um conjunto de ponteira para máquinas de movimentação de terra, compreendendo uma ponteira (11) que tem um bolso (12) aberto na parte posterior, dita ponteira exibindo um furo (16) para assentar uma chave de travamento, um adaptador (41) tendo um nariz (42) que acopla geometricamente com dito bolso (12), dito nariz sendo atravessado por um assento (43) para assentar a chave de travamento, e uma chave de travamento (61) inserida em dito furo na ponteira e em dito assento no adaptador para travar a ponteira no adaptador ; ao menos uma superficie do nariz exibe uma zona rebaixada ou com recesso obtida ao redor de seu assento para a chave de travamento; ao menos a parede do bolso que fica de face à dita superfície do nariz exibe internamente um relevo complementar de dita zona rebaixada ou com recesso; desta maneira, o acoplamento entre a ponteira e o adaptador é tornado mais forte pela interação entre ao menos duas respectivas superfícies que ficam de face uma com a da outra.
