A plenum of distributing a flow of air from an air source includes ports extending from a face element of a body. The ports are configured to direct the flow of air out of the plenum, and the ports are arranged on the face element in a first row having first length, a second row having a second length, and a third row having a third length. The first row is positioned proximate to the top element, the third row is positioned proximate to the bottom element, and the second row is positioned between the first row and the third row. In addition, the second length is greater than the first length and the third length, and a shape of the face element is configured to accommodate the first length of the first row, the second length of the second row, and the third length of the third row.

Air distribution system for a pneumatic conveying system

A system for pressurizing a tank of an agricultural air distribution system includes an air source configured to supply pressurized air and a plenum having an inlet fluidly coupled to the air source and configured to receive a flow of pressurized air. The plenum includes a face element positioned opposite from the inlet relative to a direction of flow of the pressurized air through the plenum. Moreover, the face element includes a pressurization port configured to direct the flow of pressurized air to the tank and at least one outlet port configured to couple to at least one hose to supply the pressurized air to an agricultural implement.

An agricultural product distribution system includes a fan configured to provide an air flow that fluidizes and transports particulate material throughout the agricultural product distribution system. The fan includes an impeller, an inlet position on a first axial side of the fan, and an outlet position on a peripheral side of the fan. The agricultural product distribution system includes a power transfer shaft having a first end non-rotatably coupled to the impeller, wherein the power transfer shaft extends through the inlet of the fan.

Drive system for an agricultural product distribution system

An airflow system that has a fan spacer within a fan assembly is provided for use with equipment such as work vehicles, which may include agricultural implements or other agricultural equipment. The fan spacer influences a width dimension of a fan housing interior and airflow characteristics of the fan assembly, such as output pressure and flow rate, to optimize fan performance for a particular implementation. In this way, the fan spacer allows for highly customizable fan performances by using housing spacers to modify fan housing dimensions and provide performance characteristics that correspond to what is needed for particular implementations while using common fan housing segments.

Airflow system with fan spacer for work vehicles

A pneumatic system of an agricultural implement includes a radial fan coupled with a plenum. The plenum contains outlets which distribute the airflow into a plurality of product distribution lines for application to a field. An airflow deflector plate has a back face fixed on a sidewall of a region interconnecting the fan outlet and plenum inlet to modify the airflow pattern and obtain an airflow that is at a uniform pressure and flow rate for each product distribution line. The deflector plate is tapered with a narrow edge pointed upstream and includes front face having at least one generally rectangular groove with a bottom surface extending generally parallel to the deflector back face.

Airflow deflector for radial fan of air seeder

An agricultural air seeding system, comprising: an agricultural planting implement including at least one section at least one secondary header removably attached to the at least one section, at least one attachment bar attached to the at least one section, and a plurality of application tools removably attached to the at least one attachment bar and fluidly coupled to the at least one secondary header; an agricultural air cart coupled to the agricultural planting implement; and a pneumatic distribution system fluidly coupled to the agricultural planting implement and the agricultural air cart, the pneumatic distribution system including a plurality of conduits capable of transporting agricultural product, at least one of the plurality of conduits including at least one flow obstruction such that a substantially equal air pressure is delivered to the plurality of application tools.

Equalizing air pressure on air seeders

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.
