Abstract
One or more techniques and/or systems are disclosed for seed metering for an agricultural seeder. The seed metering includes a metering member for an agricultural implement having a body configured to couple with a metering device and a raised ring formed circumferentially around a rim of the body. The raised ring defines a plurality of seed receiving portions each configured to receive a seed therein, wherein the plurality of seed receiving portions have a plurality of walls defining a continuous wall structure and forming a cavity therein. The cavity has an outwardly facing open end and one or more walls of the plurality of walls have a different height than one or more other walls within each seed receiving portion.
Claims20
A metering member for an agricultural implement, comprising:
- a body configured to couple with a metering device;
- and
- a raised ring formed circumferentially around a rim of the body, the raised ring defining a plurality of seed receiving portions each configured to receive a seed therein, the plurality of seed receiving portions having a plurality of walls defining a continuous wall structure and forming a cavity therein, wherein
- the cavity has an outwardly facing open end, and
- one or more walls of the plurality of walls have a different height than one or more other walls within each seed receiving portion.
A metering member for an agricultural implement, comprising:
- a body configured to couple with a metering device;
- and
- a plurality of protruding structures extending from the body, the plurality of protruding structures defining spaced apart seed-shaped cells therebetween and configured to receive seeds therein, wherein
- each of the seed-shaped cells have a plurality of walls with different heights, and
- at least one wall of the plurality of walls is an arcuate shaped wall having a configuration complementary to a seed shape.
A system for planting seeds, comprising:
- a metering member that receives seeds, at a seed meter input, from a seed source, and rotates to provide the seeds at a seed meter output;
- a seed meter motor that drives rotation of the metering member;
- a seed delivery system that receives the seeds, from the seed meter output, and outputs the seeds at an outlet end of the seed delivery system, into a furrow;
- and
- a motor control system is configured to generate a motor control signal to control the seed meter motor to change a motor speed of the seed meter motor to selectively provide hilldrop seed groupings or singulated seeds.
