Air seeder with GPS based on/off control of individual row units
First Claim
1. An air seeder, comprising:
- a product tank having an interior;
a plurality of product boots;
a pneumatic distribution system including an air source and a plurality of distribution lines, said air source being in communication with said product tank interior, each said distribution line being fluidly coupled with at least one corresponding said product boot;
an air lock in communication with said product tank interior and each said plurality of distribution lines, said airlock isolating the operating pressures of each of said plurality of said distribution lines from said product tank; and
,a plurality of diverter assemblies, each said diverter assembly including an inlet coupled with said air source, a first outlet coupled with at least one said distribution line, a second outlet from each of said diverter assemblies in communication with said air lock, and a diverter for selectively diverting air and entrained product from said inlet to one of said first outlet and said second outlet.

Abstract
An air seeder includes a product tank having an interior, an air lock in communication with the product tank interior, a plurality of product boots, a pneumatic distribution system, and a plurality of diverter assemblies. The pneumatic distribution system includes an air source and a plurality of distribution lines. The air source is in communication with the product tank interior. Each distribution line is fluidly coupled with at least one corresponding product boot. Each diverter assembly includes an inlet coupled with the air source, a first outlet coupled with at least one distribution line, a second outlet in communication with the air lock, and a diverter for selectively diverting air and entrained product from the inlet to the first outlet or the second outlet.

9. An air seeder, comprising:
-
a product tank having an interior; a plurality of row units; a pneumatic distribution system including an air source and a plurality of distribution lines, said air source being in communication with said product tank interior, each said distribution line being fluidly coupled with at least one corresponding said row unit; an air lock mounted to a top of said product tank, said air lock having an inlet in communication with said pneumatic distribution system, and an outlet in communication with said product tank interior, said airlock isolating the operating pressures of each of said plurality of said distribution lines from said product tank; a plurality of diverter assemblies, each said diverter assembly including an inlet coupled with said air source, a first outlet coupled with at least one said distribution line, a second outlet from each of said diverter assemblies in communication with said air locks, and a diverter; a global positioning system (GPS) providing output signals corresponding to a position of at least one said row unit; and an electrical processing circuit receiving said output signals from said GPS, and selectively controlling operation of said plurality of diverters, dependent upon said GPS output signals, for selectively diverting air and entrained product from said inlet to one of said first outlet and said second outlet. - View Dependent Claims (10)
