A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.

Seeding system with vertical array of nozzles

A seed metering system includes a volumetric meter and a plurality of row units. Each and every one of the plurality of row units includes a singulating meter, a bypass conduit, and an outlet that is common to and downstream of the singulating meter and the bypass conduit. The seed metering system further includes a dispersion unit including an inlet and a plurality of outlets and operable to disperse the plurality of seeds from the volumetric meter to the plurality of row units. The seed metering system is operable in a first mode of operation in which the volumetric meter communicates with each singulating meter via the dispersion unit to singulate the plurality of seeds. The seed metering system is operable in a second mode of operation in which the volumetric meter communicates with each bypass conduit via the dispersion unit such that the plurality of seeds are not singulated.

Seeding system

A product distribution system includes a product on demand pick-up assembly including a hopper. The hopper is configured such that an air stream flowing into the pick-up assembly entrains product therein and conveys product downstream through a plurality of conduits. The product distribution system further includes a container for storing product prior to delivery of product to the pick-up assembly and a meter and conveyor assembly configured to move product from the container to the pick-up assembly hopper such that an amount of product greater than a predetermined quantity is maintained in the pick-up assembly hopper during operation of the system.

A seeding system includes a storage tank operable to store a plurality of seeds and a dispersion unit configured to disperse some of the plurality of seeds amongst a plurality of conduits. The dispersion unit includes a sensor. A meter is operable to transfer the some of the plurality of seeds from the storage tank to the dispersion unit. The sensor is operable to produce a signal to control the transfer from the storage tank to the dispersion unit.

A seeding machine is provided with a frame comprising a center frame section and left and right wing frame sections. The frame has a planting configuration and a transport configuration. The center frame section and the left and right wing frame sections each have a hollow toolbar forming a pneumatic manifold. Individual planting units are mounted to the toolbars. The pneumatic manifold of the center frame section is automatically pneumatically coupled to each of the left and right wing frame sections by a resilient bell that forms a pneumatic path between the center frame section and the left and right wing frame sections when the frame is in its planting configuration. The pneumatic manifolds are pneumatically coupled to pneumatic seed meters on the planting units by air hoses.

Automatic pneumatic seal between frame members

A pneumatic plug is used to seal off a pneumatic pressure source from a pneumatic pressure seed meter. The pneumatic plug comprises an annular rim defining an annular cavity, a insert portion and a sealing wall. The plug is an integral rubber body. The insert portion is inserted into a pneumatic hose supplying pneumatic pressure to the seed meter. The annular rim defines an annular cavity into which the pneumatic inlet of the seed meter is received. The annular cavity is provided with two inwardly extending sealing ridges that engage the outer sidewalls of the pneumatic inlet. The sealing wall provides a pneumatic seal for the pneumatic hose.

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.

A lift and rotate agricultural implement frame comprises a main frame having a lift tube and a carrier frame slidably mounted to the lift tube. The lift tube comprises a vertically extending main support tube having planar surfaces and a corrosion resistant exterior sleeve. The corrosion resistant exterior sleeve comprises corrosion resistant plates corresponding to the planar surfaces of the main support tube. Each of the plates has an interior surface and an exterior surface. At least one of the corrosion resistant plates adjoins another plate. One of the adjoining plates is provided with an overhang that extends past the exterior surface of the other plate of the pair. The plates are fillet welded to one another between the overhang and the other plate. The plates are also provided with oblong openings having oblong edges. The oblong edges are fillet welded to the main support tube to couple the sleeve to the main support tube.
