A seed meter assembly includes a motor, a seed reservoir, and a metering member having a seed side facing the seed reservoir and a non-seed side. The motor is configured to drive the metering member in a rotational direction moving from upstream towards downstream. The metering member includes a plurality of apertures for picking up seeds from the seed reservoir under the influence of a pressure differential. A cell diverges from an aperture of the plurality of apertures towards the seed side to define a surface recessed therefrom. The cell is configured to receive one of the seeds and is elongated between a first end defining a furthest extent of the cell in an upstream direction and a second end defining a furthest extent of the cell in a downstream direction. The aperture of the plurality of apertures is disposed closer to the second end than to the first end.

A vacuum system that includes a planter frame. A row unit bracket couples to the planter frame. A fan couples to the planter frame and draws air through a row unit. An exhaust duct extends through the row unit bracket. The exhaust duct couples to the fan and discharges airflow from the fan towards the ground. A diffuser reduces a speed of and/or redirects the airflow as the airflow exits the exhaust duct.

A work vehicle includes a commodity delivery system that distributes commodity from a commodity source between a plurality of delivery runs, a commodity container pressure delivery system that may deliver selected pressure to the commodity container, and an electric control system coordinating operation of the commodity container pressure delivery system with a commodity manifold valve member delivering the commodity into a selected delivery run helping to match or otherwise balance pressure within the container storing the commodity with the selected commodity delivery path for control of siphoning and/or floating of the commodity as it is dispersed from the commodity container and into selected ones of the plurality of delivery runs of the work vehicle.

A flow control insert for an agricultural metering system includes a body configured to couple the flow control insert to a housing of the agricultural metering system. The flow control insert also includes a shoulder extending from the body. The shoulder is configured to engage a channel in a meter roller to control flow of particulate material within the channel along a rotational direction of the meter roller.

A vacuum system that includes a planter frame. A row unit bracket couples to the planter frame. A fan couples to the planter frame and draws air through a row unit. An exhaust duct extends through the row unit bracket. The exhaust duct couples to the fan and discharges airflow from the fan towards the ground.

A first source of an electromagnetic signal is configured to illuminate or radiate the evaluation channel through which a series of particular seeds pass. For example, the electromagnetic signal comprises a pulse with at a primary reference phase and primary reference magnitude. A first receiver of the electromagnetic signal comprises a detector to determine or identify a first seed-related characteristic (e.g., first seed characteristic) based on an observed primary phase and an observed primary magnitude. For instance, a seed treatment device is configured to treat or spray discharged particular seed with a seed treatment based on the estimated characteristic, or to reject non-conforming seeds that do not meet seed specifications.

Provided are a material broadcasting device, an unmanned aerial vehicle, and a material broadcasting method. The material broadcasting device includes a material picker, a material receiver, a material feeder, and a controller. The material picker includes a housing having an upper opening and a lower opening; and a material picking wheel located at the lower opening and driven by a driving member to rotate. The upper opening is in communication with a material box. Material picking cavities for accommodating materials are provided on the material picking wheel. The controller is electrically connected to the driving member. The material receiver is located below the material picking wheel and is in communication with the material feeder.

A placing unit for a seed drill includes at least two furrow-opening disks and at least two devices for delivery of particulate products from at least one reservoir, the respective ejection outlets of which are situated between the two opener disks in a manner mutually offset along the direction of advance. The placing unit also includes a body carrying the disks and devices. The placing unit includes an elongated assembly for firming of the product or products deposited at the bottom of the furrow, and an interface for linking with the body for the seed-firming assembly, which includes an end for fixation with the interface and an opposite bracing end. The linking interface includes at least two fixation sites for the corresponding end of the assembly, offset longitudinally relative to one another along the direction of advance.

An agricultural planting implement is used to plant seed in a field. The implement includes an electrically-driven seed meter that is spaced on a toolbar of the implement. The seed meter, or other metering member, is a precision meter that is used to control the volume, spacing, and location of a seed that is delivered from a meter to the field. A seed source, such as a seed cart or hopper, is attached to the seed meters to provide an on-demand amount of seed to the meters for planting in the field.

A seed distributor evenly delivers seed from a bulk seed tank via hoses to seed bins on row planter units. The distributor has a circular chamber for receiving seeds from the seed tank. An internal cone in the distributor deposits the seeds 360° around the chamber. Seed tubes extend through the sidewall of the chamber. Pressurized air is introduced into the chamber and picks up seeds on the floor of the chamber and pass through the seed tubes for delivery by the hoses to the bins. The distributor may also include air tubes aligned with the seed tubes to further assure even distribution of seeds to the bins.
