  • Air entrainment device for seed delivery
    Patent number: 8800458
    Abstract: A seed delivery device including a frame defining at least one seed chamber. The frame includes a sidewall and an air permeable floor. Seed can be received and deposited on the air permeable floor through an input port. An air input channel is utilized to introduce an air stream into the seed chamber and direct it through the air permeable floor such that seed is lifted from the air permeable floor to an outlet port. An air bypass channel is configured to separate the air stream into a first stream that is directed through the air permeable floor and a second stream that is directed through the bypass channel and recombined with the first stream, at a point prior to the output port.
