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.

An assembly includes first and second shafts and first and second sprockets. The first shaft has a first and second ends and a first longitudinal axis of rotation. The first sprocket is attached to the first shaft proximate the first end of the first shaft. The first sprocket rotates with the first shaft. The second shaft is spaced from the first shaft by a distance, the second shaft having a first end spaced from the first end of the first shaft by the distance, a second end spaced from the second end of the first shaft by the distance, and a second longitudinal axis of rotation substantially parallel to the first longitudinal axis of rotation. The second sprocket is attached to the second shaft proximate the second end of the second shaft. The second sprocket rotates with the second shaft. The distance is adjustable.

An improved particulate metering system is provided. The system includes an air flow origin and a plurality of particulate accelerators. A single particulate source is in communication with the particulate accelerators. Each of a plurality of operated conveyances can be in operable communication with the single particulate source and one of the particulate accelerators. The system includes a confluence of the air flow and the particulate within the mixing area of each of the particulate accelerators. Each of a plurality of discharges can be associated with the particulate accelerators. The operated conveyances can operate at different rates. The system can include one or more gearboxes adapted to be inverted and controlled by a second drive system. The improved system and controls provide variable application rates of particulate across rows in a field.

A self-contained seed tender (20) includes a plurality of bins (48) as well as a conveyor system (30) with a lower conveyor (32) and a shiftable lift conveyor (34). The lift conveyor (34) is shiftable between a stowed, travel position astride the bins (48) and a central, rearwardly extending delivery position. A deployment assembly (38) serves to sequentially pivot the lift conveyor (34) about an upright axis, followed by lateral translation thereof to the central use position. The conveyor (34) can then be rotated and elevated as desired for off-loading of seeds. The tender (20) may also be used for delivery of other types of agricultural particulates.

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 system for replenishing the supply of a particulate agricultural product in the tank of an air cart. A mixture of air and product comes out of a venturi delivery system and enters in a multiplicity of inlet hoses. Then the product enters into inlet tubes of various lengths and release angles from which product particles are gently spread strategically forming a pile that is more or less horizontal to ensure even feeding of meters during dispensing operations. Then the air exits through one or more fine screens to avoid product escaping as well and is conveyed through the exhaust hoses until reaching an air diffuser. The air diffuser has a series of varying size holes or louvers at the bottom so the air can come out at a uniform low velocity which minimizes any discomfort to nearby operators.
