An agricultural seed planter is provided. The agricultural seed planter has a large diameter rotating planting wheel with fingers or teeth spaced around the periphery of the planting wheel. The teeth are positioned so as to achieve a spacing of the seeds when planted in the soil. The teeth have a small dimple in the end and an even smaller hole passing through the entire length. The dimple provides a place for the seed to sit in and the small hole allows positive or negative air pressure to be transmitted to the seed. The negative air pressure creates a vacuum suction that attaches the seed to the teeth, and the positive air pressure releases the seed from the teeth. In an example implementation, the wheel includes many individual mechanical modules that are linked together to form the wheel.

A system, method, and device for displaying spacing information of discharged seeds. A seed disc may be configured to rotate at a disc velocity to discharge seeds. A seed sensor may be configured to generate a first signal indicative of a discharge time of a seed. A drive module may be operably coupled to the seed disc and may be configured to generate a second signal indicative of the disc velocity of the seed disc. A discharge time for the discharged seeds may be determined based on the first signal and/or the disc velocity of the seed disc may be determined based on the second signal. A seed disc index may be determined for discharged seeds based on the disc velocity of the seed disc and the discharge time for the seed. Spacing information may be determined for the seeds by comparing the determined seed disc indexes.

A pneumatic seed delivery system is provided for use with planter for row-crop planting an agricultural field in which the pneumatic seed delivery system may use high pressure air to accelerate seeds that are singulated from a seed meter to match ground speed when planting. The pneumatic seed delivery system includes an air accelerator arranged downstream of a release location of the seed meter. The air accelerator may define a pneumatic device such as an air conveyor or air amplifier that merges a primary airflow with a controllable supplemental airflow to provide a correspondingly controllable combined airflow that carries and accelerates the singulated seeds so that the seeds can be released with a rearward horizontal seed velocity component that approximates a forward ground speed of the planter to reduce seed tumble.

A work vehicle includes a delivery system with a run. The run includes an upstream flow structure having an inlet that is configured to receive metered commodity and a suction generator structure with a flow passage that is in fluid communication with the inlet. The flow passage includes a venturi profile with a restricting section and an expanding section. Furthermore, the run includes a downstream flow structure configured to receive the metered commodity via the flow passage and an airstream that conveys the metered commodity in a downstream direction through the downstream flow structure. A compressed air source is configured to provide pressurized air through the flow passage to create suction to suck the metered commodity away from the metering system and toward the downstream flow structure.

A particle delivery assembly of an agricultural row unit includes a particle tube configured to receive a particle and to deliver the particle toward a trench in soil. The particle tube includes a first body portion, a second body portion, and a hinge coupled to the first body portion and to the second body portion. The hinge is configured to enable the first body portion and the second body portion to pivot relative to one another between an open position of the particle tube and a closed position of the particle tube.

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.

An agricultural planting system for controlling the depth of an opener device comprising: an agricultural planter; an opener device mounted on the agricultural planter for engaging the ground of a field; a gauge wheel mounted on the agricultural planter for rotating on the ground of the field; a GPS device coupled to the agricultural planter, the GPS device configured to determine a location of the agricultural planter in the field; and a controller in electrical communication with the agricultural planter and the GPS device, the controller having predetermined settings associated with a map of the field, the controller being configured to select a relative elevation of the opener device and the gauge wheel based at least in part on the location determined by the GPS device, and produce, based on the location, a signal for adjusting the depth of engagement into the ground of the opener device.

Systems, methods and apparatus for adjusting the depth of a trench opened by a row unit of an agricultural planter. The row unit includes a trench depth adjustment assembly configured to modify the furrow depth. In one embodiment, the depth adjustment assembly may include a gear box having one or more gears which engage with a gear rack. The gear box may be pivotally connected to a depth adjustment body supporting a rocker that adjusts upward travel of gauge wheel arms. In another embodiment, the depth adjustment assembly may include a depth adjustment arm having a screw receiver that cooperates with a driven screw that adjusts the position of the depth adjustment arm acting on the gauge wheels to adjust trench depth.
