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 dual seed meter 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.

A particle delivery system of an agricultural row unit includes a particle belt having a particle acceleration section. The particle belt is configured to receive a particle, to accelerate the particle at the particle acceleration section, and to expel the particle toward a trench in soil. The particle delivery system includes a first hub assembly engaged with the particle belt at a first location and a second hub assembly engaged with the particle belt at a second location. The particle acceleration section is disposed generally at the first location, a substantially no-slip condition exists between the first hub assembly and the particle belt at the first location and between the second hub assembly and the particle belt at the second location, and the first hub assembly and the second hub assembly are configured to stretch the particle belt at the particle acceleration section to accelerate the particle.

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 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.

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 seeding system for seeding large and small seeds includes a plurality of dispensing apparatuses mounted on an implement frame each comprising a first furrow opener mounted and a second furrow opener spaced laterally from the first furrow opener. A singulating meter is operative to dispense the large and small seeds through a meter discharge. A first seed conduit is connected to the first furrow opener and the meter discharge, and a second seed conduit is connected to the second furrow opener and the meter discharge. A selector is operative in a large seed mode to maintain the connection of the first seed conduit to the meter discharge while disconnecting the second seed conduit, and the selector is operative in a small seed mode to maintain the connection of the first seed conduit to the meter discharge while connecting the second seed conduit to the meter discharge.

A novel seed metering device which accommodates a large diversity of seed types and sizes by utilizing a rotating two crevice helical pattern in which individual seeds are channeled around two opposing rotors and dispensed singularly or volumetrically based on desired outcome. The two opposing rotors, each with a half set of creviced helical patterns, are adjustable to open and close in order to accommodate seed size and type. When the rotors are adjusted all the way in, the primary crevice is closed and the secondary crevice remains open for the smaller seed sizes to pass through and evenly dispense. As the rotors are adjusted out away from each other, incremental increases can be achieved in order to find the ideal crevice width to accommodate the seed diameter for singular or even disbursement.
