Seed meter disc having agitation cavities

摘要

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

1. A seed meter for an agricultural planter, comprising:
a meter housing including a seed housing; an opening for communicating seeds into said seed housing; a seed pool area for collection of said seeds disposed near a bottom end of said seed housing; and a seed disc rotatably mounted within said meter housing, said seed disc being disposed horizontally adjacent to said seed pool area, said seed disc further including a plurality of seed apertures, said seed apertures disposed to rotate along a seed aperture path, a portion of said seed aperture path being adjacent to said seed pool area, said seed disc further having a plurality of cavities disposed along said seed aperture path, wherein each of said cavities has an outer perimeter larger than an outer perimeter of said seed apertures, wherein a central axis of each of said seed apertures is outside of an outer perimeter of said cavities, said central axis being substantially normal to a surface of said seed disc, said surface generally defining a seed side of said seed disc, wherein said cavities include a bevel, said bevel oriented to face away from said seed pool area as said cavities become adjacent to said seed pool area.
