Abstract

A device for discharging particulate material from a container with a table to support the particulate material includes a feed unit which is movable on the table for discharging the material through a peripheral outlet opening, and a drive for driving the feed unit; the feed unit includes at least two spaced feeding elements disposed to successively move the material in a direction from the center of the table towards the outlet opening; the feeding elements are arranged, during a full cycle of movement of the feed unit, to be alternately active within an arbitrary section of the table extending between the center part and outlet opening for feeding a layer of particulate material in front of them in the direction toward the outlet opening and inactive while returning to a starting position.

Dependent claims

An apparatus for feeding particulate material from a container of the type having a bottom having an opening, said apparatus comprising a table for location beneath the bottom of the container to receive the material under gravity flow onto said table from the opening, said table having an outer peripheral edge and a center, a feeding unit disposed on said table for movement toward and away from at least a portion of said outer peripheral edge, said feeding unit including at least one slide member carried on said table and having a first surface facing generally outwardly in a direction of movement toward said outer peripheral edge and a second surface facing generally inwardly in a direction of movement away from said outer peripheral edge, said first surface being shaped to engage and move material toward said outer peripheral edge to discharge material from the table and said second surface being shaped to minimize movement of material towards the center as said at least one slide member is moved generally away from said outer peripheral edge.
