A metering system for distributing particulate material includes a meter housing containing a metering wheel. An inlet and/or outlet of the meter housing provides a projection extending into the opening of the inlet and/or outlet so that the flow of particulate material is optimized. This can provide even distribution of such material, including at low rotating speeds such as 5 RPM, while using a polyurethane metering wheel with straight vanes. In one aspect, projections extending into the inlet on opposing sides can substantially form an hourglass shape, and the outlet can comprise a substantially diagonal shape, analogous to a parallelogram, instead of more traditional rounded/rectangular shapes.

A meter wheel system for a dry agricultural product applicator can include a bank of meter assemblies made from modular meter units. In one aspect, each meter assembly in the bank can be made from modular meter units. The modular meter units can be connected in a stacked configuration to provide a specific overall length to achieve a corresponding flow rate and then banked together to form the system. A bank of meter assemblies made from modular meter units can be secured between top and bottom plates. The plates can be bolted to each other and have receptacles that receive protrusions from top and bottom surfaces of the meter assemblies. Lengths of meter assemblies can be picked based on particular delivery rates for the section it feeds. An overall length of each meter assembly can be a multiple of a length of the modular meter unit.

Meters for fertilizers, small seeds, and chemicals include a housing defining a loading chamber, a rotatable metering disk provided with a receiving surface and a discharge surface, the disk including metering orifices; a ring including a discharge opening, and an insulating barrier arranged in the interior of the housing, the insulation barrier forming an insulating chamber on the rotatable disk and defining an inlet region of the disk and an output region of the disk; a metering bulkhead associated with the insulating barrier in the inlet region of the rotating disk with metering orifices loaded, the metering bulkhead being arranged on the rotatable metering disk so that a lower portion of the metering bulkhead is coplanar to the receiving surface of the rotatable disk.

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 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.

Meters for fertilizers, small seeds, and chemicals include a housing defining a loading chamber, a rotatable metering disk provided with a receiving surface and a discharge surface, the disk including metering orifices; a ring including a discharge opening, and an insulating barrier arranged in the interior of the housing, the insulation barrier forming an insulating chamber on the rotatable disk and defining an inlet region of the disk and an output region of the disk; a metering bulkhead associated with the insulating barrier in the inlet region of the rotating disk with metering orifices loaded, the metering bulkhead being arranged on the rotatable metering disk so that a lower portion of the metering bulkhead is coplanar to the receiving surface of the rotatable disk.

A seed conveyor assembly that delivers seed to a planting surface in a controlled manner to maintain seed placement accuracy within a trench. In one embodiment, a seed guide for a seed conveyor assembly includes a relief portion and an introduction portion that includes at least one protrusion. The protrusion is angled from a side of the introduction portion toward the center of the introduction portion. The end of the protrusion is proximate the center of the introduction portion being further from the relief portion.

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 biasing system is provided for use with an associated run selector device having a valve body member movable within a housing between opposite first and second run selection positions selecting respective first and second commodity distribution runs of the associated run selector device. The biasing system includes a first biasing element on the housing, and a second biasing element on the valve body member. The first and second biasing elements are movable relative to each other between opposite first and second biasing system positions together with the associated valve body member being moved relative to the housing between the opposite first and second run selection positions. The first and second biasing elements are mutually biased against each other to urge each other apart and towards a one or the other of the opposite first and second biasing system positions.

An implement for dispensing agricultural product. The implement comprises a bin for holding agricultural product, with the bin including a plurality of product openings for dispensing agricultural product from the bin. The implement additionally includes a plurality of metering devices secured to a bottom of the bin and configured to receive agricultural product from the bin through the product openings. The implement further includes a plurality of flow tents positioned within the bin. Each flow tent is positioned between a pair of the product openings. The flow tents extend upward from an interior side of the bottom of the bin so as to guide agricultural product towards the product openings.
