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 air manifold system for supplying an agricultural product to a plurality of metering devices comprises a product hopper having a product flow cavity, the product cavity separated from a first plenum by an air agitator sandwiched between the first plenum and the product flow cavity. The hopper comprises a plurality of nozzles extending through a wall of the hopper. A venturi assembly is in fluid communication with at least one nozzle. A first forced air stream flows through the first plenum and the air agitator into the product flow cavity to agitate and entrain agricultural product in the first air stream, and the first air stream carries the entrained agricultural product into the nozzles. A second forced air stream flows through the venturi assembly to accelerate the first air stream and the entrained product towards and through the supply hoses connected to the nozzles.

A seed planter for creating and planting together the combination of both seed and contents of a seed growing environment. The seed planter includes, for example, a wheeled frame configured with at least one soil opener and at least one soil closer for planting a field. A seed growing environment aggregator assembly has at least one input opening for receiving a plantable portion of a seed growth medium and seed from the seed hopper and at least one discharge opening for discharging an aggregation of the plantable portion of the seed growth medium and seed to the at least one soil opener for planting a desired growing environment in the field.

Sowing element for precision agricultural seeders comprising a device for selecting the seed, of the type which is formed of a perforated disc having opposing faces that are subject to a pressure differential and a pressurisation device associated with the disc for applying the pressure differential to the faces of the disc, the pressurisation device including a pressurisation bell combined with the disc so as to pneumatically couple thereto in order to guarantee said pressure differential, wherein the bell is rotatably idle with respect to the disc.

The invention relates to a device for metering a granular or grainy material in a distributor machine, comprising a housing; an inlet opening which is formed on the housing and through which a granular or grainy material can be introduced in the housing for metering; an outlet opening which is formed on the housing and through which the granular or grainy material can be discharged out of the housing after metering; a metering space which is formed in the housing in such a way that granular or grainy material in the housing can be moved from the inlet opening via the metering space to the outlet opening; a metering wheel which is arranged in the metering space on a drive shaft, and which is configured to meter the granular or grainy material supplied via the inlet opening; a mounting opening which is formed on the housing and via which the metering wheel can be exchangeably mounted in the metering space; and a mounting component which is detachably arranged in the mounting opening in a mounted position, and this in turn is arranged at least partially welded onto the housing, wherein the mounting component has a receiving unit for detachably receiving the metering wheel, in such a way that the metering wheel received on the receiving unit is mounted on the drive shaft when arranging the mounting component in the mounted position, and in such a way that, when detaching the mounting component from the mounted position, the metering wheel is forcibly detached from the drive shaft (6), such that the metering wheel can be removed from the metering space in this way and can be detached from the housing together with the mounting component. A distributor machine is also provided for distributing a granular or grainy material, such as seeds, fertiliser or grit.

A work vehicle with a metering system, airflow system, and a covering structure moveable between various positions for user access includes features that facilitate assembly and/or disassembly of the metering system. The work vehicle has a venturi structure with a plurality of venturi tubes that are disposed in a compact arrangement.

A metering device for dispensing agricultural product from a bin. The metering device comprises a housing enclosing an interior space, and a metering assembly removably received within the interior space of the housing. The metering assembly is configured to convey agricultural product through the metering device. The metering assembly comprises a rotatable sub-shaft, a first metering wheel positioned on the sub-shaft and configured to rotate with the sub-shaft, a second metering wheel positioned on the sub-shaft and configured to rotate with the sub-shaft, and a dividing element positioned on the sub-shaft between the first metering wheel and the second metering wheel.

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.

The present invention provides a protective wear cover which may be utilized in a metering device housing to protect the housing in an area which may be subjected to high impact by product flow. The protective wear cover may be installed inside the metering device housing at the venturi induction zone. The protective wear cover may be manufactured from a highly wear resistant material. The shape of the protective wear cover may be suited to conform to the metering device housing in the protected area to ensure a tight fit and negligible effect on air flow. This protective wear cover may therefore serve as a sacrificial barrier which prevents wear on the metering device housing and may be periodically replaced when worn. Replacing the protective wear cover negates the need to replace the whole metering device housing.
