ABSTRACT:
A metering device for particulate material in which backups and caking of material is inhibited by the provision of a "live" metering gate consisting of an upper blocking section and a lower material contacting surface. The lower surface is continually moved in the direction of material flow at a speed approximately equal to or slightly greater than the material flow speed. An elongate rotatable rod carried at the lower end of a blocking plate preferably provides the material contacting surface.
The gate is vertically adjustable so that the volumetric flow rate of material can be controlled. In a preferred embodiment the gate is located above the end of the material bearing surface and is adjustable along an axis which diverges from vertical by an appreciable angle, preferably about 45.degree..
The transverse dimension of metered material is also controlled by means of two blocking members which extend inwardly toward each other from behind the gate. The clearance between the blocking members can be controlled to limit the width of metered material to a desired amount, and also to achieve a singulated metering pattern.
