  • Patent number: 10383282
    Abstract: 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.

  • Patent number: 10178180
    Abstract: 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.

  • Patent number: 9956899
    Abstract: 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.
