Seed Meter

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, said seed housing defining a seed pool area into which seeds are communicated and collected; and a seed disc rotatably mounted within said meter housing, said seed disc having a seed side surface defining a seed plane, said seed disc having a central axis and a direction of rotation, said seed disc further having a plurality of seed apertures spaced radially outward from said central axis, said plurality of apertures defining a seed path along said seed plane, said seed side surface having a plurality of cavities intersecting said seed path, each of said cavities having a portion inward of an inner radius of said seed path, and each of said cavities further having a surface recessed relative to said seed plane; and a singulator having a plurality of lobes disposed to remove seeds from said seed apertures, said lobes contacting said seed side surface wherein said cavities rotate sequentially past and adjacent to said lobes during operation.
