An inductor box for an agricultural implement includes an inlet configured to receive agricultural product from a tank. The inductor box also includes a housing having a cavity therein. The cavity is configured to receive the agricultural product from the inlet. The inductor box includes a gate configured to be removably inserted between the inlet and the cavity, to block the agricultural product from entering the cavity while disposed between the inlet and the cavity, and to enable the agricultural product to enter the cavity while removed from being disposed between the inlet and the cavity. The inductor box includes a first guide coupled to the housing and configured to direct the gate away from the inlet. The first guide is disposed between the gate and the inlet while the gate is disposed between the inlet and the cavity.

A metering unit for granular material includes a conveyor disk driven by a drive motor and rotating approximately concentrically to an inner cover surface of a housing. The conveyor disk has a recess for the reception of at least one grain to be separated via at least one revolution of the conveyor disk. In the interaction with a groove-shaped and/or slanted profile of the inner cover surface, the recess forms a conveyor pocket for conveying one grain or a plurality of grains in the direction toward an outlet opening extending approximately tangentially from the inner cover surface. For varying an axial distance to the inner cover surface and/or a width of the conveyor pocket, the conveyor disk, which is rotationally fixedly connected with the drive motor, is adjustable in the axial direction of the drive motor.

A metering and mixing system of solid particulates for a rotary seed dispenser in agricultural equipment for sowing, wherein the rotary seed dispenser is mounted under a seed feeder. The rotary seed dispenser is driven at the bottom by a planter drive system, which provides rotation to a spinning disc provided with a number of calibrated orifices through which the seeds housed in the disc orifices fall on a given point of the agricultural equipment. The metering and mixing system of solid particulates includes a solid particulate feeder that is positioned between the seed feeder and the rotary seed dispenser.

Various planting machines and planting methods are described. A planting method may include filling a seed pool with first-type seed, metering the first-type seed from the seed pool with a metering member, and then evacuating the first-type seed from the seed pool. The method may further include filling the seed pool with second-type seed, metering the second-type seed with the metering member, evacuating the second-type seed from the seed pool, and then refilling the seed pool with the first-type seed. First-type and second-type seed may be evacuated to separate temporary storage chambers, and the seed pool may be filled from the temporary storage chambers, as well as from bulk storage containers. A seed valve of a planting machine may include temporary seed storage chambers for different seed types. The seed valve may fill and evacuate a seed pool through rotation of various valve members and selective application of a vacuum.

An air seeding system and method includes a manifold mounted across a plurality of row planter units. Electric motors are mounted on the manifold and are operatively connected to the seed meters. A microprocessor or controller adjusts the speed of the motors in response to field data input so as to adjust the rate of seed dispensement to achieve desired plant population. The motor speeds can be adjusted on the fly, without stopping the air seeder. The system senses ground speed, senses the raised and lowered positioned of the row planter units, and senses any blockage of the row planter units. The motors eliminate the need for a ground drive wheel.

The invention relates to a single seed dispenser (10) for a precision automatic sower comprising a cover (11) for seeds to be distributed joined to a body (12) containing a cavity (24) in communication with an aspirator of the seeds via a conduit (22) inserted in a hole (23) realised on the body (12), a distribution disc (13) with holes (38, 54) contained in a compartment delimited by said body (12) and by said cover (11); a driving disc (31) joined through pins (53) to the distribution disc (13), both discs being put into rotation by means of a shaft (29) actuated by an actuator for commanding rotation of the discs (13, 31); and a selector device (14) for the seeds pivoted on the edge of the body (12), where the selector device (14) comprises a plate (142) which presents, on a side facing the centre of the distribution disc (13), at least two toothed portions (143, 144), having teeth of different sizes and a curved sector (59) mounted against the surface of the distribution disc (13) opposite to the plate (142) and is provided with protrusions (591) having inclined surface (592) facing the distribution disc (13) at holes (38) therein.
