Abstract
A filling system for a silo is provided, wherein the silo is filled by blowing grain, hay, or other suitable material into the silo through a duct that extends up the silo wall, and that turns and enters into an inlet opening at the top of the silo wall, whereupon the fill material is blown toward the geometric center of the silo at the top thereof, to strike a baffle or deflector, whereupon the fill material may fall from the upper center of the silo toward the bottom thereof. A pressure relief system is provided in the form of a vent that also has a baffle or deflector for engagement of large dust particles thereagainst, and in addition is provided with a screen-type collector, with an open hole for assurance that the vent will not become blocked. Particularly novel opening mechanisms are provided for the fill door and the vent door, for opening them by an operator located at the ground level. A novel opening is provided for an access door above the center deflector or baffle. The fill material may be provided to the silo using reduced energy requirement for delivery of the fill material, and without requiring climbing by an operator to the roof or top of the silo.
