Abstract: A transfer conveyor apparatus has a horizontally oriented receiving hopper defined by walls and a floor. A transition auger slopes upward and rearward from a bottom end thereof located in a rear portion of the receiving hopper. A plurality of hopper augers extend from the front wall to the rear portion of the receiving hopper. A right hopper auger is in proximity to and parallel to the right side wall and a left hopper auger is in proximity to and parallel to the left side wall. The hopper auger shafts are parallel and spaced apart by a spacing distance substantially equal to or less than the hopper auger diameter, and an auger drive is operative to rotate the hopper augers and the transition auger.

Abstract: A pneumatic conveyor apparatus includes a separation chamber with an input port in a wall thereof. A vacuum duct has an output end connected to the input port. An auger discharge conveyor has a lower auger intake opening in a bottom portion of the separation chamber. A suction device creates an air stream flowing from the intake end of the vacuum duct through the input port into the separation chamber, and out through an upper portion of the separation chamber. A housing connects the input port to a first portion of the auger intake opening, and a screen covers a second portion of the auger intake opening such that the air stream flows from the input port into the first portion of the auger intake opening and flows out of the second portion of the auger intake opening through the screen into the separation chamber.

Abstract: A valve assembly comprising a body member forming a channel having first and second ends, forming a seat surface within and at the first end of the channel about an orifice that faces in the direction of the second end, the channel forming a first coupler at the second end, a closure member forming a closing surface and an oppositely facing bearing surface, the closing surface configured to be received on the seat surface to close the orifice, the closing member received within the channel with the closing surface facing the seat surface, a spring member having first and second ends and received within the channel with the first end of the spring member contacting the bearing surface and an adjustment member having first and second ends and forming a second coupler at the first end of the adjustment member that cooperates with the first coupler to mechanically link the adjustment member within the channel in various relative juxtapositions, one of the adjustment member and the body member forming an outlet pa

Abstract: An intake conduit apparatus comprises an intake conduit adapted at a downstream output end thereof for connection to an intake of a vacuum conveyor, and adapted at an upstream input end thereof to facilitate entry of granular material. Ramps slope inward and downstream from the interior wall of the intake conduit, and there is a vent hole through the wall of the intake conduit adjacent to a downstream end of each ramp such that air enters the intake conduit adjacent to the downstream end of each ramp.
