Abstract
A pneumatic seed delivery system is provided, including a bin with a plenum at the bottom separated from the bin by a membrane to permit the upward flow of air from the plenum into the bin, and a tube extending through a side wall of the bin to provide fluid communication from an outer surface of the bin to an inner surface of the bin. One end of the tube is disposed inside the bin and adjacent to the screen, and a second open end of the first seed distribution tube is disposed outside the bin. In this manner, seed in the bin can be propelled up the tube by forcing air into the plenum, passing the air through the membrane and through seed located between the membrane and the first open end of the tube. This seed will then move up the tube and be carried to a remote location for use. This structure may also be provided by modifying a bin with an existing metering system removable through an opening in the bottom of the bin by removing a cover from the opening, removing the metering device, and inserting a device having plenum and tube structures into the opening.
