  • Patent number: 12144282
    Abstract: Various methods, systems, and devices for flexible and accurate seed spacing control in a seed planting system. The various embodiments receive singulated seed from a metering device and control movement of the seed toward a seed spacing device that receives the seed. The seed spacing device, which is disposed near the soil surface, independently controls the ejection of the seed from the device and thus the spacing of the seed in the furrow.
    Type: Grant

  • Publication number: 20240315163
    Abstract: 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 rapidly conveyed from the seed chamber to the furrow by a precisely controlled air pulse to eliminate variation enable high planting speeds.

  • Publication number: 20190072114
    Abstract: The disclosed apparatus, systems and methods relate to devices, systems and methods for the selective application of down pressure or downforce to a row unit. Each row unit has a dual-action actuator which is in fluidic communication with the hydraulic system for independent control of the supplemental downforce. The pressure line can be directly routed to the lift chamber for a constant supply of up pressure, with down pressure selectively applied to the down chamber for accurate control of the supplemental downforce system.
