Bucket conveyor

Bucket conveyor to load heaped aggregate materials from a plane on which the heap lies onto another higher plane, comprising a framework revolvably anchorable at one end along a vertical axis to an apparatus which receives aggregate, consisting of a substantially triangular metallic structure bearing two pairs of pulleys and of a metallic boom or extension which bears at a free end a pair of pulleys farthest from the zone of discharge of the buckets, said triangular structure and extension being connected together at one end with a hinge having its axis perpendicular to a plane which contains the framework, said hinge being positioned between said pulleys on said extension and on said triangular structure;

• a length of chain;
• junction links and buckets positioned on said chains around said pairs of pulleys, said chain forming a catenary between two pairs of pulleys further including screws wherein the height of the free end of the extension and of the pair of pulleys solidly fixed to that end above the ground can be adjusted with said screws to move the pair of pulleys lengthwise in relation to the extension.
