At their lower edge (6) excavators are provided with a tooth arrangement consisting of two parts (1 and 2), one part (2) being attached to the bucket (6) and the other part (1) being exchangeable. The two parts (1 and 2) are held together by means of a male and female relationship and a transverse aperture (3 and 25) with a locking body (4). When the exchangeable part (1) becomes worn it may start to become unstable. The object of the present invention is to eliminate this drawback and this is achieved in that the locking body (4) comprises two opposing flat surfaces, provided with one or more spacers (15-20) intended to restrict approach of the two surfaces towards each other.
Les bords inférieurs (6) d'excavatrices sont pourvus d'un mécanisme à dents constitué de deux éléments (1 et 2,), l'un d'entre eux (2) étant rattaché au godet (6) et l'autre (1) étant amovible. Ces deux éléments (1 et 2,) sont réunis par un système de raccord mâle et femelle ainsi que par le biais d'une ouverture transversale (3 et 25) comportant un corps de verrouillage (4). Lorsque l'élément amovible commence à être usé, il devient instable et l'objet de cette invention est d'éliminer cet inconvénient. Cette amélioration est rendue possible par le fait que le corps de verrouillage (4) comporte deux surfaces plates en opposition, pourvues d'une ou de plusieurs cales (15, 20) servant à restreindre le rapprochement des deux surfaces.
