ABSTRACT:
A swinging gate assembly is provided for use in an electronic livestock feeding station and an automated sorting system. The gate assembly has a generally V-shaped configuration in plan view with first and second side openings defined on each side of the V-shape. A gate panel has a first side edge pivotally connected to the frame for rotation about a substantially vertical first pivot axis at the apex of the V-shape. The gate panel is swingable about the first pivot axis between a first position in which the first side opening is closed by the gate panel and a second position in which the second side opening is closed by the gate panel. A mechanical actuator and locking assembly is provided for moving the gate panel between the first and second positions and locking the gate panel in a selected one of the positions.
