In one aspect, a calibration method for a seed meter may include controlling an air pressure source to apply an initial air pressure to a seed transport member of the seed meter defining a plurality of seed cells. The method may further include controlling the seed meter to rotate the seed transport member relative to a seed chamber of the seed meter containing a plurality of seeds. The method may additionally include performing a calibration cycle for the seed meter, which may include monitoring a first parameter indicative of a number of empty seed cells as the seed transport member rotates, iteratively adjusting the air pressure from the initial air pressure as the first parameter is being monitored, and when the first parameter crosses a first threshold, recording the associated air pressure as a minimum air pressure for the seed meter.

A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.

Disclosed herein are various embodiments of dual seed meters having a metering housing having first and second seed disks with a plurality of openings arranged along a curved path of each disk, wherein the disks overlap to form a convergence region such that seed traveling along the curved paths is delivered to a single point. Certain implementations also have a vacuum chamber defined between a first wall of the metering housing and the first and second seed disks and a seed chamber defined between a second wall of the metering housing and the first and second seed disks.

A plurality of different controllers on an agricultural machine are time synchronized. A first controller, identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, and generates a timestamp indicating a time at which the action is to be taken. An action identifier and the timestamp are sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the timestamp based upon the actuator delay.

The present invention provides an agricultural delivery system which may selectively deliver agricultural product (e.g., seeds or fertilizer) along one or more paths to row units according to a real-time location determined for the delivery system. The delivery system may include: a rotating drum configured to separate individual product for depositing along paths to row units; a sectional control system which may include wheels or gates for selectively cutting off product in the paths; and a controller in communication with a positioning system and the sectional control system. In operation, as the delivery system moves through a field, the controller may continuously determine a location for the delivery system. The controller may then operate to adjust individual product delivery, via the sectional control system, according to the location.

A pneumatic single-grain sowing machine includes: a closed housing; a rotatably driven separating device, which has circularly arranged perforations; and a fan for producing a pressure difference between the housing and the interior of the separating device, the separating device thus being designed to separate seed by use of the perforations with the aid of the pressure difference, the separating device being designed as a closed hollow drum having two side walls arranged at a distance from each other. The separating device is designed to compensate slight housing expansions.

A system for seed orientation includes a seed disk capable of rotation in operation and having at least one singulator to adjust an orientation of seed to a desired seed orientation for placement within a furrow during planting. A vision system in proximity to the seed disk determines seed orientation data for seed on the seed disk.

A seed conveyor assembly that delivers seed to a planting surface in a controlled manner to maintain seed placement accuracy within a trench. In one embodiment, a seed guide for a seed conveyor assembly includes a relief portion and an introduction portion that includes at least one protrusion. The protrusion is angled from a side of the introduction portion toward the center of the introduction portion. The end of the protrusion is proximate the center of the introduction portion being further from the relief portion.

An agricultural machine includes a motor configured to drive a seeding system that is, itself, configured to meter and deliver seed from the agricultural machine. The agricultural machine also includes a sensor configured to sense a characteristic of the seeding system and a skip detector component, that receives the sensor signal and detects a seed skip in the seeding system. Based on the detected seed skip, a processing system generates an operating parameter of the motor, and controls the motor based on the operating parameter.

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.
