Fastening Device For A Collector Of Solid Remains Swiveling At The End Of A Mobile Arm In Particular Fastening Device For Articulated Buckets Of A Crust Shovel

摘要

The invention relates to an attachment device for attaching a collecting container (120), including: a) at least one pivot member (115) pivotably mounted about an axis (500) on a mobile arm and including at least one first transverse arm provided with a first attachment means (117) and at least one second transverse arm (118) with axial bores (119); b) at least two fasteners attached to said collecting container, the first fastener (121) being provided with a second attachment means (122) interacting with the first attachment means and the second fastener (123) including axial bores (124); c) a pin (130) which is insertable and slidable into said axial bores when the latter are aligned. At least one bore of a group, referred to as a central bore (1240), is conical and is surrounded by two bores of the other group, referred to as peripheral bores (1190, 1191), which are cylindrical. The pin (130) has a conical shoulder complementary to the central bore. The invention can be used for dual bucket scoops used in potrooms for producing aluminium.
