Abstract
Material dislodging means for a bottom unloading type silo having a central vertical shaft projecting upwardly from the bottom adjacent an outlet opening therein and including a series of chains connected at one end to said shaft in vertically spaced relationship and of progressively greater length with the shortest being lowermost, said connections comprising openings extending diametrically through said shaft to receive said ends of said chains to provide effective, long lasting flexible connections for said chains. The outer ends of the chains have digging and raking elements connected thereto by means of sockets on said elements which receive at least the terminal outer link of each chain. Pin means connect the opposite ends of the chains respectively within said openings in said shaft and said sockets on said elements.
