Controlled air pulse metering apparatus for an agricultural planter and related systems and methods

摘要

The devices, systems, and methods herein use air pressure to dispense seed into the ground in a controlled manner. In certain embodiments, a valve is actuated to push a single seed out of a seed chamber. The seed can be conveyed from the metering housing and through a seed delivery apparatus to the furrow at high speed. The seed is rapid conveyed from the seed chamber to the furrow by a precisely controlled air pulse to eliminate variation and enable high planting speeds.
