Air grain conveyor system

And air grain conveyor comprising:

• a generator for generating high velocity air;
• means on said generator for cooling said high velocity air;
• an exit seal on said generator;
• means for adjusting said exit seal to minimize air leakage in said seal;
• a grain ejector for receiving said high velocity air;
• a hopper for grain on said ejector;
• a grain feed section between said hopper and said ejector whereby grain is drawn into said ejector by said high velocity air;
• a convey section attached to the ejector section whereby the grain is conveyed by said high velocity air;
• and
• a discharge section for the grain is connected to said convey section.

An air grain conveyor comprising:

• a rotating generator for generating high velocity air including a continuous blade consisting of flights on a rotatable shaft inside a housing;
• a stationary exit seal for receiving the high velocity air from the generator;
• means for adjusting said exit seal to minimize air leakage in said exit seal;
• an ejector housing for receiving said high velocity air from said exit seal;
• a grain hopper on said ejector housing whereby grain is drawn into said ejector housing by said high velocity air;
• a convey line for conveying the air borne grain away from the ejector housing by said high velocity air;
• a discharge section for the grain is connected to said convey section;
• means in the discharge section for slowing air borne grain;
• and
• a receiver for the grain is attached to the discharge section.

An air grain conveyor comprising:

• a high velocity air generator;
• an L-shaped grain ejector section having a housing for receiving high velocity air from the air generator;
• a hopper for grain on the L-shaped ejector section;
• means connecting the air generator to the housing wherein a negative pressure draws grain from the hopper into the housing;
• a convey section on the housing whereby a positive pressure from the high velocity air conveys the grain in a convey line on the convey section;
• a discharge section for the grain;
• said generator is a rotatable screw blower;
• said screw blower comprises a continuous blade consisting of flights on a rotatable shaft, an inner housing for the flights and shaft, said inner housing having a cylindrical outer housing, an air exit seal for the cylindrical housing, and an outer stationary housing for the exit seal;
• and
• said air exit seal comprises a casing for receiving the cylindrical housing having a beveled shoulder, a seal in the casing for sealing the area between the casing and the cylindrical housing, a converging seal adjustable toward and away from the cylindrical housing beveled shoulder, and an exit port for high velocity air exiting the inner housing.
