DEVICE FOR FEEDING MATERIAL OUT OF SILOS OR FROM STACKS

摘要

The invention concerns a device for feeding of material from a bottom supporting said material to a central outlet by means of a feed screw performing a wandering movement about the center of the bottom and a rotation about its own axis and in which the driving means for the screw are mounted onto a turning disk mounted in the center of the bottom and surmounted by a protecting casing. The invention intends to prevent the often occurring formation of vaults in the material. To this purpose the casing leaves a portion of the turning disk uncovered and has a feed edge extending downwards towards the disk so as to drive off the material from the outlet opening during rotation of the disk and thereby improve its uniform feed through the outlet opening.
