Publication number: 20100101469Abstract: Left and right main hoppers offset laterally from each other on opposite sides of the centerline of a seeding machine provide an operator access area between the hoppers. A third hopper located forwardly of and between the two main hoppers has a capacity less than that of each of the main hoppers for refuge or male seed. The hoppers are sized to maximize productivity. In one embodiment, first and second hoppers communicate with downstream conduit structure, and valve structure selects one or the other of the first and second hoppers for delivery of the material. The valve structure can be operated remotely and can be map based. Alternatviely, selectively blockable nozzle structure is located in the first and second hoppers. Easily changeable connector structure facilitates row pattern selection and hose routing.Type: ApplicationFiled: January 6, 2010Publication date: April 29, 2010Inventors: Donald Keith Landphair, Christopher Allen Myers, Patrick Eugene Pinkston, Richard Hugo Clark, Chris Warren Foster, Chad Erik Braden, Robert Wallace Martin

Patent number: 7025010Abstract: A product-on-demand delivery system applies an agricultural product, such as seed, to a field. The system includes a frame that mounts a main hopper, a splitter fitting, a primary product hose, a secondary product hose, a primary application unit and a secondary application unit. The main hopper has an air nozzle wherein an air stream through the air nozzle entrains product within the air stream and delivers the air/product to the primary outlet hose. The splitter fitting has a splitter inlet flow-connected to the primary product hose and two splitter outlets flow-connected to the application units. The secondary application unit is coupled to the primary product supply hose by the secondary product hose connected at an outlet branch. The outlet branch is connected at an angle such that a product flow velocity vector in the primary product supply hose at the outlet branch is at an obtuse angle to a flow velocity vector of product flowing through the outlet branch.Type: GrantFiled: April 21, 2004Date of Patent: April 11, 2006Assignee: Deere & CompanyInventors: Robert Wallace Martin, Nathan Albert Mariman, Bradley John Meyer

Patent number: 6725788Abstract: A pneumatic coupler for an agricultural seeding machine comprises a hollow tube having an inner portion and an outer portion that are separated by a radially extending flange. The radially extending flange has an inner surface adjoining the inner portion and an outer surface adjoining the outer surface. A flexible and resilient gasket is fitted over the inner portion and adjoins the inner surface of the radially extending flange. The inner portion is further provided with radially extending catches that are located on resilient axially extending tongues formed in the inner portion. When mounted to receiving apertures the catches contact the interior side of the receiving aperture and the flexible and resilient gasket forms an air seal between the exterior surface of the receiving aperture and the inner surface of the radially extending flange.Type: GrantFiled: March 26, 2002Date of Patent: April 27, 2004Assignee: Deere & CompanyInventors: Scott Charles McCartney, Robert Wallace Martin, Nathan Albert Mariman, Donald Keith Landphair

Patent number: 6352042Abstract: A seed meter is provided with a stationary housing having an inlet for receiving seed and an outlet for dispensing metered seed. A rotatable circular member is located adjacent the stationary housing and forms a seed puddle there between. The circular member is provided with seed receiving cells for transporting individual seeds from the seed puddle to the outlet. An internal seed knockout assembly having a rotatable wheel drives trapped seed from seed receiving cells into the outlet.Type: GrantFiled: October 10, 2000Date of Patent: March 5, 2002Assignee: Deere & CompanyInventors: Robert Wallace Martin, Netza Portillo, James Irwin Lodico
