Title
(DE) EIMERREINIGUNG
(EN) BUCKET CLEANOUT
(FR) NETTOYAGE DE GODET
Abstract
(EN)
Disclosed are excavators or other power machines having a lift arm structure (e.g., 230; 434; 534) with a bucket (e.g., 405; 505) coupled to an arm (e.g., 434; 534) to pick up material during a digging or scooping operation, and a bucket cleanout device (e.g., 420; 520) to aid in removal of material from the bucket. The bucket cleanout device includes components (e.g., 410; 510) which are rotatably coupled to a support structure, such as the arm, an implement carrier and/or the bucket and configured to aid in removal of material during a material dumping movement of the bucket.

(FR)
L'invention concerne des excavateurs ou d'autres machines à moteur comprenant une structure de bras de levage (par exemple 230; 434; 534) dotée d'un godet (par exemple 405; 505) accouplé à un bras (par exemple 434; 534) permettant de saisir un matériau pendant une opération de creusement ou de ramassage, et un dispositif de nettoyage de godet (par exemple 420; 520) permettant de contribuer au retrait de matériau du godet. Le dispositif de nettoyage de godet comprend des éléments (par exemple 410; 510) qui sont accouplés de façon rotative à une structure de support, telle que le bras, un support d'outil et/ou le godet et configurés pour contribuer au retrait du matériau pendant un mouvement de déversement de matériau du godet.
