Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
224 words
Apparatus for unloading bulk material from an annular storage heap of said material, comprising an annular track means circumferentially disposed around the center of the storage heap adjacent the inner foot of the heap; a scraper loader including a scraper jib means; a supporting frame means pivotably supporting the scraper jib means so that the latter extends across the storage heap and is movable in a vertical plane, the pivot point between the frame means and scraper jib means Also being adjacent the inner foot of the storage heap; pivot means centrally disposed within the storage heap connected with said supporting frame means and defining a vertical axis for rotation of the frame means and scraper jib means thereabout; running gear means arranged on said frame means for circumferential movement on the annular track means; conveyor belt means supported by the frame means to rotate therewith about said vertical axis; said conveyor belt means having a receiving end and a discharge end, said receiving end being arranged adjacent the pivot point between the frame means and the scraper jib means so that material removed from the storage heap by the scraper jib means is transferred to the conveyor belt means; said discharge end of the conveyor belt means being arranged adjacent the pivot means so that material can be discharged therefrom for further conveying.

Claim 3
Dependent Claim
76 words
Apparatus according to claim 1 wherein the scraper jib means comprises a first jib part pivotally attached to the supporting frame means about a horizontal axis at the pivot point therebetween; the first jib part including an outboard end removed from said pivot point; a second jib part pivotally attached to said first jib part outboard end for movement on a horizontal axis; and means for raising and lowering said jib parts either jointly or individually.
Claim 4
Dependent Claim
29 words
Apparatus according to claim 1 wherein said supporting frame means comprises a cantilever girder extending radially over the storage heap and from which the scraper jib means is suspended.
