A pneumatic delivery system for particulate agricultural products includes one or more compartment for containing and supplying one or more particulate product. An inductor assembly separately receives and fluidizes the particulate products and conveys the fluidized products to a metering assembly. The metering assembly separately meters each of the product flows and transfers the metered flows to one or more delivery units for applying the products. The pneumatic delivery system can be used on various implements, including planters and applicators for applying seeds, fertilizer, pesticides and other products.

A row unit of an agricultural planter includes a seed meter. The seed meter includes a seed disk within a seed meter housing. The seed disk is positioned in the seed meter housing such that the disk rotates and includes a seed release point. A drive member is operatively connected to the seed disk such that the drive member selectively rotates the disk. The seed disk is angularly positioned and is a conical-shaped member with a central axis and includes seed cells radially positioned about an outer portion. The seed disk is substantially non-perpendicular to the central axis. An air pressure source also is included to adhere seed to the disk.

The present invention involves a seed firmer with a pusher attachment that extends the life of the seed firmer and improved brackets for mounting the same to a planter. The improved brackets allow for different mechanisms of mounting seed firmers to different locations on a planter. The brackets have portions for attaching and mounting to the planter, and a housing for accepting and securing the firmers. The brackets allow for better positioning of firmers on a planter, ease of mounting and/or replacement of firmers, and improved firmer functionality.

A planting machine for forming a trench for planting seeds and/or fertilizer in a ground surface, including a frame that supports a planting assembly having a cutting tool and a gauge that sets the height of the cutting tool so as to determine a depth of the trench formed by the tool, wherein the assembly includes a linkage coupled between the frame to the gauge and an actuator to allow for remote adjustment of the linkage, in order to vary a planting depth of the trench.

A metering device for dispensing agricultural product from a bin. The metering device comprises a housing enclosing an interior space, and a gate assembly removably received within the interior space of the housing. The gate assembly is configured to guide agricultural product through the housing. The gate assembly comprises a product gate comprising an arcuately-extending gate valve. The product gate at least partially defines a channel within the interior space of the housing through which agricultural product can flow. The gate assembly further comprises a gate key configured to selectively secure the product gate within the housing. Rotation of the gate key is configured to cause a corresponding rotation of the product gate.

A metering device and a distributing machine for metering free-flowing bulk material, in particular seeds and/or fertilizer, from a container, using a metering device. The metering device includes a delivery channel with an inlet and a metering outlet, and a pressure compensation section disposed in the delivery channel between the inlet and the metering outlet. The pressure compensation section is actuated by a pressure difference between the delivery channel and the surroundings.

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.

A seed meter is provided for planting multiple types of seed and rapidly switching between the types being planted in a single planting pass of a planting session of row-crop planting. The seed meter has a split seed meter reservoir with a pair of seed meter chambers flanked by or next to a pair of seed disks. Activation and deactivation of the seed disks within the seed meter are synchronized to selectively deliver one type of seed from one of the seed meter chambers for delivery out of a single seed tube of the seed meter, which may provide absolute and instantaneous on-the-go seed switching within a single row from each seed meter.
