摘要： A port interface for a pneumatic distribution system includes a first flow passage configured to receive fluidized particulate material from an outlet port of a header and to output the fluidized particulate material to an outlet line. The port interface also includes a second flow passage configured to receive a purging airflow and to output the purging airflow to the outlet line. In addition, the port interface includes a knife valve having a blade with a first opening and a second opening. The blade is configured to move between a first position in which the first opening is substantially aligned with the first flow passage and the second opening is substantially aligned with the second flow passage, and a second position in which the first opening is substantially aligned with the second flow passage and a solid portion of the blade is substantially aligned with the first flow passage.

摘要： One embodiment describes a seed planting system that includes a seed storage tank to store seeds; a seed meter fluidly coupled to the seed storage tank via a flow path, in which the seed meter receives seeds from the seed storage tank and distributes the seeds to ground engaging opener assemblies; and a seed deflector coupled to the seed storage tank directly above the flow path, in which the seed deflector guides the seeds from the seed storage tank into the flow path at an angle relative to a vertical axis of the flow path.

摘要： A separator for separating granular material, such as seed, fertilizer or pesticide, from a material-laden airflow (FI) includes a separator zone (Z) having an inlet (11) for a material-laden airflow, a material outlet (13) and an air outlet (12, 12′), and at least two separator parts (15, 15′), which extend only substantially along a material flow (FM) in the separator zone (Z) and between which is formed a separator gap (12, 12′), which is sufficiently narrow to allow air, but not the granular material, to pass through it. At the material outlet (13), the separator gap (12, 12′) is at least partially open, viewed in a direction which is substantially parallel with the material flow (FM), so that material which gets stuck in the separator gap (12, 12′) is allowed to leave this by means of displacement principally along the material flow (FM).

摘要： The present invention provides a pneumatic distribution system for use with agricultural equipment, such as air drills and air carts, in which hoses may be held at a manifold connection having articulated control. The manifold connection may hold multiple couplers for hoses, and each of the couplers may be configured to allow substantial rotation in a first plane perpendicular to the ground. In addition, the manifold connection may be configured to allow substantial rotation in a second plane parallel to the ground. As a result, the manifold connection may be held proximal to a mechanical hitching point between agricultural equipment. This, in turn, may allow elimination of excess hose lengths and greater ease of handling when the agricultural equipment is separated and the hoses are disconnected.

摘要： The seed distribution tower of an air seeder has a distribution head that splits a single, primary stream of conveying air and seeds into a plurality of secondary streams for delivery to openers that deposit the seeds into the ground as the seeder advances. The outlets through which the secondary streams exit the head are constructed as modules that can be individually installed and replaced without disassembling the entire head. Shut-off valves and/or flow sensors may or may not be incorporated into certain or all of the modules to provide optimum user flexibility.

摘要： An air cart has a drop chute for conveying an agricultural product such as seed, from a metering device to a venturi portion of a product conveyance tube. The drop chute has a contoured downstream sidewall resulting in changes in drop chute width which introduce vortices providing an enhanced product flow. The downstream sidewall has an inward sloping region reducing the drop chute width beginning closely adjacent the metering device and continuing down about one-third the way from the metering device to the conveyance tube, and an abrupt corner causing an increase in drop chute width near the product conveyance tube followed by a curved region creating a gradual further increase in width terminating adjacent to the product delivery tube. A large low speed vortex is created near the inward sloping region and a small strong vortex is created adjacent the curved region.
