A metering system for an agricultural vehicle includes meter rollers, each including protrusions driving flow of flowable particulate material in response to rotation of the meter roller. The metering system also includes a drive shaft driven in rotation and includes transmission assemblies that each correspond to a respective meter roller. Each transmission assembly includes a respective moveable gear actuatable to engage each of a plurality of gears to establish a respective gear ratio corresponding to one of a plurality of different speeds of the respective meter roller relative to the drive shaft.

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.

An air flow system for an air seeding machine includes a tank configured to store an agricultural commodity, a plenum, conduits, and a blower configured to push air flow through the plenum and the conduits to the tank. The plenum includes a uniformly-sloped side wall and geometric first and second ends bounding the side wall. The plenum further includes bleed ports coupled to bleed conduits and configured to conduct air flow to an interior volume of the tanks. The plenum further includes primary ports coupled to primary conduits and configured to conduct air flow to the tanks. The primary conduits receive commodity from the tanks to be deposited in the soil. The geometry of the plenum facilitates an adequate balance of air flow between the primary and bleed conduits so that the commodity most-effectively enters the air stream conducted by the primary conduits.

A fluid line connection for a pneumatic distribution system for an agricultural air seeder includes a female connector having an inside diameter with a groove and a male connector configured for internal assembly with the female connector. The male connector has an external tab that engages the groove to retain the male connector to the female connector when the female connector is rotatingly assembled with the male connector. The female connector is removed by rotating and disassembling from the male connector to access a conveyance tube or manifold for servicing these parts. A sealing member is assembled between the male and female connectors to form a fluid seal. A primary tube can be assembled between two fluid line connections to form a quick connect assembly. A fitting connector and a locking ring are assembled with a fluid line connection to retain a primary tube thereon for an air drill.

A device for distributing bulk material, such as seed material, includes a flow path having at least one conduit for conveying the bulk material from a bulk material source towards an agricultural area, and a blockage detection device in the flow path. The blockage detection device includes at least one sensor, which is mounted to the outside of the line and is configured to register mechanical vibrations of the line, as well as an evaluation unit in signal communication with the sensor, which is configured to detect a blockage as a function of the registered mechanical vibration. A method for detecting a blockage includes a sensor that identifies blockage as a function of the detected mechanical vibration.

A distribution orifice system for a dry product applicator with a pneumatic conveyance system is provided which redirects product that drags along a surface(s) of a delivery line's wall(s) back into a main central or primary airflow portion that carries the product downstream through the pneumatic conveyance system. The distribution orifice system may deflect the agricultural product's particulate material radially inward away from the delivery line's wall while longitudinally advancing it in a downstream direction. The system may include a ring ramp that can be renewed by uninstalling the ring ramp, flipping it 180-degrees, and reinstalling it to present an intact ramp surface facing upstream and the wore ramped surface facing downstream.

A near-plug monitoring system includes particle flow rate sensors coupled to or downstream of a distribution header, wherein the distribution header is coupled to a primary distribution line and a plurality of secondary distribution lines, the distribution header is configured to receive a flow of a granular product from the primary distribution line and to divert the flow of the granular product among the secondary distribution lines. The system includes a controller configured to receive feedback from the particle flow rate sensors, to determine a real-time flow rate of the granular product in the secondary distribution lines, to determine if a near-plug condition is occurring in at least one secondary distribution line based on the real-time flow rate, and to automatically provide a control signal to alter one or more operating parameters of the pneumatic conveyance system when the near-plug condition is occurring to resolve the near-plug condition.

A product delivery conduit for an agricultural product hopper assembly includes an inlet segment and an outlet segment. The inlet segment is configured to receive agricultural product from an inlet conduit, the outlet segment is configured to output the agricultural product to a storage area within a hopper of the agricultural product hopper assembly, the outlet segment is configured to be oriented substantially vertically while the agricultural product hopper assembly is in a working position, the inlet segment and the outlet segment are configured to position an outlet of the product delivery conduit above the storage area while the agricultural product hopper assembly is in a non-working position, and the outlet segment is configured to be oriented downwardly while the agricultural product hopper assembly is in the non-working position to enable the agricultural product to flow into the storage area.

An apparatus for separating grains of seed or fertilizer includes a separating device having a housing with a housing base for mounting on an agricultural machine. A releasable housing cover is arranged on the housing base in a releasable manner. A grain sump receives the grains introduced into the housing interior to be separated out. A rotatable separating disc having openings is positioned in the housing interior. An overpressure region is formable in the housing cover on a front side of the separating disc during operation, such that a flow can form from the overpressure region through the openings to the rear side of the disc and grains separated can be localized near the openings. A grain transfer device includes a feed, a wall bushing and an outlet, wherein the separated grains can be introduced through the feed into the bushing and discharged from the housing interior through the bushing.

A seed distributor evenly delivers seed from a bulk seed tank via hoses to seed bins on row planter units. The distributor has a circular chamber for receiving seeds from the seed tank. An internal cone in the distributor deposits the seeds 360° around the chamber. Seed tubes extend through the sidewall of the chamber. Pressurized air is introduced into the chamber and picks up seeds on the floor of the chamber and pass through the seed tubes for delivery by the hoses to the bins. The distributor may also include air tubes aligned with the seed tubes to further assure even distribution of seeds to the bins.
