摘要： A seed delivery device including a frame defining at least one seed chamber. The frame includes a sidewall and an air permeable floor. Seed can be received and deposited on the air permeable floor through an input port. An air input channel is utilized to introduce an air stream into the seed chamber and direct it through the air permeable floor such that seed is lifted from the air permeable floor to an outlet port. An air bypass channel is configured to separate the air stream into a first stream that is directed through the air permeable floor and a second stream that is directed through the bypass channel and recombined with the first stream, at a point prior to the output port.

摘要： A alignment system is described for a blocking member for the transfer of seed from a seed meter with a seed meter housing to a delivery system with a delivery system housing. The blocking member may have a blocking face adjacent a seed path of the seed meter, the blocking face opening to a seed passage, and the seed passage extending through the blocking member to an interface with the delivery system housing. A first recess may be included on the blocking member, and a second recess may be included on the delivery system housing. When the seed passage of the blocking member is correctly aligned with the delivery system, a protrusion on the delivery system housing may be configured to seat firmly in the first recess and a protrusion on the seed meter housing may be configured to seat firmly in the second recess.

摘要： Metering devices for an agricultural implement are provided for applying a field input, for example, pneumatically delivered granular product including seed or fertilizer or sprayed liquid product including fertilizer and the like, to an agricultural field. In the applying of the field input, the rate of application of the dispensers of one section of the implement can be collectively varied in relation to the rate of application of the dispensers of a different section of the implement frame.

摘要： A seed meter is provided having an endless belt as a seed transport member together with a pressure differential to hold the seed onto the belt. The use of an endless belt as the seed transport member enables the spatial orientation of the seed transport member to vary from location to location along the path of the belt where different seed meter functions are performed. The belt allows greater freedom in determining the location of the seed pick-up region and the seed release or removal region beyond the constraints of a fixed diameter seed disk. The belt further allows for a narrow envelope seed meter which can cross-feed seed into a substantially vertically oriented delivery device.

摘要： A planter, in certain embodiments, includes a structural air manifold. The planter may include a hollow structural member configured to bear and/or distribute static and dynamic loads of the planter. The structural member may include a hollow interior having a first port and a second port. A plurality of individual planting units and a fan may be mounted to the structural member and coupled to the hollow interior at the first and second ports, respectively, via a conduit. The hollow interior may provide a path for forced airflow between the first and second ports to enable pneumatic operation of a feature of the agricultural seed planter. Further, each planting unit may include a seed meter pneumatically coupled to the fan. An orifice may be disposed in the first or second port to restrict the airflow through the port and to the seed meter.
