Patent number: 9956899Abstract: 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.Type: GrantFiled: July 24, 2017Date of Patent: May 1, 2018Assignee: CNH Industrial Canada, Ltd.Inventors: Martin J.

Publication number: 20180035613Abstract: 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.Type: ApplicationFiled: July 27, 2017Publication date: February 8, 2018Inventors: Ka Po Catherine Hui, Martin J. Roberge, Dennis George Thompson
