A meter roller for an agricultural metering system includes a spindle having a driven shaft, a first ring, and a second ring. The first ring and the second ring are rigidly coupled to the driven shaft, and the driven shaft is configured to engage a drive shaft to facilitate rotation of the spindle. The meter roller also includes a sealing ring longitudinally disposed between the first ring and the second ring. An outer diameter of the sealing ring is less than or equal to an outer diameter of the first ring and an outer diameter of the second ring, and the sealing ring is formed from a material having sufficient resilience to enable the sealing ring to stretch to facilitate disposition of the sealing ring between the first ring and the second ring.

One embodiment describes a seed planting system that includes a seed storage tank to store seeds; a seed meter fluidly coupled to the seed storage tank via a flow path, in which the seed meter receives seeds from the seed storage tank and distributes the seeds to ground engaging opener assemblies; and a seed deflector coupled to the seed storage tank directly above the flow path, in which the seed deflector guides the seeds from the seed storage tank into the flow path at an angle relative to a vertical axis of the flow path.

An air cart for distributing air entrained particulate material from a chamber or tank to a plurality of distribution lines for application to an agricultural field has a tank refilling feature utilizing air flow from the cart distribution system or from a dedicated pneumatic source. The cart conveying system air flow is diverted and passed through an assembly containing multiple venturis which also receives particulate material from a supply source. The air entrained material from the source is conveyed to and gently deposited in the cart tank. Exhaust air from the tank may be directed back into the cart conveying system or vented through an air diffuser located beneath the cart. Exhaust air which is directed back to the cart conveying system may return to a location closely adjacent that from which it was originally diverted.

A rotary valve comprising a rotor shaft support assembly for maintaining a rotor shaft 5 in a level orientation when the rotor shaft is supported at a single end only. The rotor shaft support assembly (101) comprises a removable casing end plate (102) and a bearing assembly (106) for supporting an end portion of the rotor shaft (104) inserted into the rotor shaft support assembly (101) and through a rotor shaft aperture (105) of the removable casing end plate (102), and is adjustable to correct any deviation of 10 the pitch of the rotor shaft (104) from a level orientation relative to the removable casing end plate (102) when the rotor shaft (104) is supported at a single end only by the rotor shaft support assembly (101) with the inserted end portion of the rotor shaft (104) supported within the removable casing end plate (102) and the bearing assembly (106).

An agricultural product delivery system and method is provided. The agricultural product delivery system includes a feeder for receiving particulate materials and a storage tank for holding particulate materials. A control system controls a filling system for providing particulate materials to the feeder. The control system is configured to communicate with a filling system to substantially maintain an alignment between the filling system and the feeder.

A sanding system for a rail vehicle includes a housing of a cellular wheel sluice having an inlet located at the top and an outlet located at the bottom, a pivotably mounted cellular wheel having a plurality of cells, and a motor that is coupled with the cellular wheel. The sanding system further includes a container connected to the inlet of the cellular wheel sluice for receiving brake sand, or a feed line connected to the inlet of the cellular wheel sluice for transporting brake sand, and a discharge line connected to the outlet of the cellular wheel sluice for transporting brake sand. The motor for driving the cellular wheel is thereby arranged above the inlet.

A system is provide for filling a pressurized tank of an air cart or other storage element while operating to deliver product to a ground engaging tool, such as for seeding or fertilizer placement. A rotary air lock coupled between a feeder and a storage tank includes a plurality of vanes providing pockets in between for holding particulate materials, The rotary air lock rotates the pockets from the feeder to a sealed area and from the sealed area to the storage tank, As such, the rotary air lock transfers the particulate materials to the storage tank while substantially maintaining a pressure in the storage tank. The system may be filled during, field operations, and a filling or conveyor system may be controlled via a vehicle to vehicle (V2V) operation.
