Abstract
A planting unit for a seeding machine is disclosed having a frame member and a seed meter mounted thereto. The seed meter has a housing and a metering member rotatably mounted therein. The metering member has a sidewall with an inner surface and an outer surface and a rim portion adjacent an outer edge of the sidewall. The inner surface of the side wall and the housing form a trough at a bottom portion of the metering member to hold a seed pool. A mechanical seed delivery system takes seed from the metering member and moves seed to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine.
Claims13
A planting unit for a seeding machine comprising:
- a planting unit frame member;
- and
- a seed meter mounted to the planting unit frame member, the seed meter having
- a housing and
- a metering member rotatably mounted inside the housing, the metering member having a sidewall with an inner surface and an outer surface, the sidewall having a rim portion adjacent an outer edge of the sidewall, the inner surface of the sidewall and the housing forming a trough at a bottom portion of the metering member to hold a seed pool, the inner surface of the sidewall of the metering member at the trough being oriented at an angle between 5° and 75° relative to a vertical vector pointing upward at the outer edge of the sidewall wherein the metering member is rotatably mounted in the housing for rotation about an axis that is inclined relative to a horizontal plane as well as inclined to a vertical plane extending fore-aft and a vertical plane extending transversely of the seeding machine.
A planting unit for a seeding machine movable in a travel direction, comprising:
- a seed meter having a metering member mounted for rotation about an axis, the metering member having a sidewall extending to an outer edge, the sidewall having inner and outer surfaces, a rim portion of the sidewall adjacent the outer edge having apertures extending through the sidewall, the metering member adapted to adhere seed to the apertures to sequentially move seed to a release position;
- and
- a mechanical seed delivery system operable to take seed from the metering member at the release position and sweep seed in a direction substantially cross-wise to a direction of travel of the seed on the metering member as the metering member rotates and move seed to a discharge location adjacent a seed furrow formed in soil beneath the seeding machine.
A planting unit for a seeding machine comprising:
- a planting unit frame member;
- and
- a seed meter mounted to the planting unit frame member, the seed meter having
- a housing;
- a metering member rotatably mounted inside the housing for rotation about an axis, the metering member having a sidewall extending axially and radially forming a concave inner surface and convex outer surface, the sidewall having a rim portion adjacent an outer edge of the sidewall with a plurality of apertures extending through the sidewall between the inner and outer surfaces wherein the axis is inclined relative to a horizontal plane as well as inclined to a vertical plane extending fore-aft and a vertical plane extending transversely of the seeding machine.
