Seed delivery system
A seed delivery system having a housing with an input opening at a first end and a discharge opening at a second end. The input opening is adjacent a seed meter and is adapted to receive and transport seeds from the seed meter to a first of a plurality of seed transport rollers disposed within the housing.
1. A seed delivery system, comprising:
a housing having a seed receiving end and a seed exit end;
a plurality of seed transport rollers disposed within the housing, wherein the plurality of seed transport rollers have a plurality of seed pockets; and
a variable speed component configured to drive the seed delivery system at a first speed exceeding the forward ground speed of the seed delivery system such that a seed breaches a surface of a soil in a seed trench and a second speed slower than the speed of the seed delivery system;
wherein the housing has an inner wall adjacent a delivery path having a plurality of elongated fins adapted to center a seed in relation to the inner wall;
wherein a height of the elongated fins along a length of the inner wall decrease from an outer edge of the inner wall toward a center of the inner wall.
2. The seed delivery system of claim 1 wherein the plurality of seed pockets are separated by teeth.
3. The seed delivery system of claim 1 wherein the adjacent seed transport rollers rotate in opposite directions to form a seed delivery path.
4. The seed delivery system of claim 2 wherein the plurality of seed transport rollers are geared and timed to one another and the teeth on one seed transport roller are aligned with the teeth on the next seed transport roller.
5. The seed delivery system of claim 1 wherein the housing has a delivery section having a first conduit for delivering granular material to a furrow and a second conduit for delivering low pressure liquid fertilizer to a furrow.
6. A seed delivery system, comprising:
a housing having a seed receiving end and a seed exit end; and
a plurality of seed transport rollers disposed within the housing, wherein the plurality of seed transport rollers have a plurality of seed pockets;
wherein the housing has an inner wall adjacent a delivery path having a plurality of elongated fins along the delivery path adapted to center a seed in relation to the inner wall;
wherein a height of the elongated fins along a length of the inner wall decrease from an outer edge of the inner wall toward a center of the inner wall.
7. The system of claim 5 wherein the second conduit is forward of the seed exit end of the housing.
