Abstract (en)
[origin: WO2015168198A1] A seed metering system, for use on a row crop planter, selects individual seeds from a seed reservoir and dispenses the seeds singularly at a controlled rate. A direct drive seed metering system includes a seed disc having a plurality of suction apertures with a recessed pocket adjacent to an aperture. The recessed pockets act to agitate seeds in the seed reservoir and to direct seed flow towards the apertures. A seed path relief system provides for allowing the placement of the seeds such that they are released from an outer edge of the seed disc. An adjustable seed singulator is mounted adjacent to the face of the seed disc where inner and outer blades are adjusted radially to compensate for the singulation of various seed sizes and shapes. The seed disc is driven via engagement of an internal gear with the external gear of an independent drive motor.
