Chain arrangement for drag-chain conveyors

Year	Description
1991	Invention patented by Gert Braun and Ernst Braun on January 15th, 1991. Abstract: A chain arrangement for drag-chain conveyors. The chain arrangement includes a round-link chain with vertical chain links, horizontal chain links and pushers fastened on horizontal chain links. The pushers engage with pusher projections into the respective horizontal chain links. The outer radius of the chain link arc members of the vertical chain links is selected smaller than the inner radius of spherically-shaped recesses in the pusher projections. The resulting play ensures that the pushers travel without jamming and enter without problems into the guide surfaces of the upper portion of the conveyor trough of the drag-chain conveyor.
