  • Publication number: 20250228154
    Abstract: A circular seed distribution manifold delivers seed from a bulk tank to bins on row planter units. The manifold has a circular chamber formed by a plurality of modules joined side to side. The modules include outwardly radially extending tubular barbs connected to hoses extending to the bins. Pressurized air is introduced into the chamber through an opening in the floor of the manifold to create a fluidized bin or mixture with the seeds evenly distributed around the chamber. The air pressure carries the seeds out the barbs, through the hoses, and into the bins for planting. The barbs have an inlet flush with the perimeter wall of the manifold to minimize plugging.

  • Patent number: 12052944
    Abstract: A seed planter is provided with a plurality of single or paired discs with each pair adapted to form furrows to receive seeds. Each disc is provided with a sensor to detect rotational speed of the disc. Each sensor transmits a signal corresponding to the rotational speed of the disc to a tow vehicle having a control system which compares the disc rotational speed to the tow vehicle travel speed. If the disc rotational speed drops below a predetermined value relative to the vehicle speed, this is indicative of disc plugging and/or furrow smearing, both of which are undesirable, such that corrective action can be taken by the operator of the vehicle or an autonomous vehicle.

  • Publication number: 20220369540
    Abstract: A sensor system on the closing wheels of an agricultural planter detects rotational speed of the closing wheels, and generates a signal corresponding to the rotational speed. If the speed is below an optimum or preset speed, the operator is notified that the wheels are not rotating properly or have stopped rotating, thereby indicating improper closing of the seed furrow after the seed is planted in the furrow. A sensor system provides a method of monitoring the function of the closing wheels and generating a signal corresponding to the rotational status of the closing wheels.
