Abstract
Disclosed herein are various embodiments of dual seed meters having a metering housing having first and second seed disks with a plurality of openings arranged along a curved path of each disk, wherein the disks overlap to form a convergence region such that seed traveling along the curved paths is delivered to a single point. Certain implementations also have a vacuum chamber defined between a first wall of the metering housing and the first and second seed disks and a seed chamber defined between a second wall of the metering housing and the first and second seed disks.

A seed metering system comprising:
- (a) a metering housing;
- (b) a first seed disk within the metering housing;
- (c) a second seed disk within the metering housing;
- (d) a vacuum chamber defined between a first wall of the metering housing and the first seed disk and the second seed disk;
- (e) a seed chamber defined between a second wall of the metering housing and the first seed disk and the second seed disk;
- (f) a first vacuum channel defined in the vacuum chamber;
- and
- (g) a second vacuum channel defined in the vacuum chamber;
- wherein the first vacuum channel and the second vacuum channel define a convergence region.
A dual seed meter comprising:
- (a) a housing;
- (b) a first seed plate drive configured to drive a first seed plate within the housing;
- (c) a second seed plate drive configured to drive a second seed plate within the housing;
- (d) a first vacuum channel defined in the housing;
- and
- (e) a second vacuum channel defined in the housing;
- wherein the first vacuum channel and the second vacuum channel converge at a convergence zone.
A dual seed metering system comprising:
- (a) a metering housing;
- (b) a first seed disk;
- (c) a second seed disk;
- (d) a seed chamber defined between a first wall of the metering housing and the first and second seed disk;
- (e) a vacuum chamber defined between a second wall of the metering housing and the first and second seed disk;
- (f) a first vacuum channel defined in the vacuum chamber along the first seed disk;
- and
- (g) a second vacuum channel defined in the vacuum chamber along the second seed disk;
- wherein the first vacuum channel and the second vacuum channel converge at a convergence zone such that seeds traveling along the first seed disk and second seed disk are delivered to a single point in the convergence zone.
