摘要： An agricultural metering system includes a releasable bearing coupler configured to selectively couple a meter roller to a housing of the agricultural metering system. The releasable bearing coupler includes a shaft configured to be disposed through an opening in the housing and to engage a bearing, wherein the bearing is configured to be disposed within a recess of the meter roller to facilitate rotation of the meter roller about the shaft and to couple the meter roller to the housing via contact with the shaft. The releasable bearing coupler includes a locking segment configured to selectively interlock with a corresponding locking feature of the housing to secure the releasable bearing coupler to the housing.

摘要： A system includes an agricultural metering system a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and a corresponding first plurality of recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The first meter roller segment includes a first profile, the second meter roller includes a second profile, and the first profile is different from the second profile. The system also has a dividing ring axially positioned between the first meter roller segment and the second meter roller segment.

摘要： Disc drill agricultural implements are configured to form product rows in a planting surface of a field. The disc drill may include two different sections of row units, the first section containing single-shoot row units and the second section containing double-shoot row units. The configuration may be used to produce three sets of product rows which may be used placement of seeds, fertilizer and/or other agricultural products.

摘要： A system includes an agricultural metering system with a meter roller configured to meter product from an agricultural product storage compartment to a product distribution system via rotation of the meter roller. The meter roller includes a first meter roller segment having a first plurality of flutes and corresponding recesses, and a second meter roller segment having a second plurality of flutes and a corresponding second plurality of recesses. The flutes of the first meter roller segment are axially separated from the flutes of the second meter roller segment by a gap. The meter roller also includes a dividing ring disposed about the shaft and axially positioned between the first meter roller segment and the second meter roller segment. A width of the dividing ring is substantially equal to the gap.

摘要： A double-shoot disc-opener row unit for use with agricultural implements includes two discs that form two separate trenches in a planting surface of a field. The mechanical connection between the two discs provides an adjustable longitudinal separation between the discs to prevent an overlap between the discs from a point view perpendicular to the direction of travel of the row unit. The longitudinal separation may reduce the interference of the flow of soil from one disc from interfering with the formations of trenches by the other disc. An adjustable lateral separation between the discs may also provide for a separation between the trenches produced by the different discs.

摘要： A pneumatic valve for an agricultural product distribution system includes a fan inlet, a tank outlet, a shuttle, a control pressure inlet, and a diaphragm. The fan inlet is coupled to an air source that supplies an air stream into a primary line, which facilitates distributing a granular product to an agricultural implement by guiding the air stream from a first section to a second section of the primary line, the first section having a larger cross-sectional area than the second section. A tank outlet is fluidly coupled to a storage tank. The control pressure inlet is fluidly coupled to the second section of the primary line or to a meter housing. The diaphragm has a first side that is coupled to the shuttle and is exposed to static pressure in the storage tank and a second side that is exposed to the static pressure in the second section of the primary line or the meter housing, and aligns a shuttle hole of the shuttle with the fan inlet when the static pressure in the storage tank is not greater than the static pressure in the second section of the primary line or the meter housing by a threshold amount.

摘要： A pneumatic distribution system to distribute a granular product to an agricultural implement includes a first pressure sensor, a second pressure sensor, a valve, and a controller. The first pressure sensor is fluidly coupled to a granular product storage tank and outputs a first signal indicative of a first static pressure in the storage tank. The second pressure sensor is fluidly coupled to a primary line that pneumatically delivers the granular product to the agricultural implement by guiding an air stream from a first section with a larger cross-sectional area to a second section with a smaller cross-sectional area. The second pressure sensor outputs a signal indicative of the static pressure in the second section of the primary line. The valve is fluidly coupled between the storage tank and the primary line and selectively enables the air stream to flow from the primary line to the storage tank. The controller, which is communicatively coupled to both pressure sensors and the valve, instructs the valve to enable the air stream to flow from the primary line to the storage tank until the first static pressure is greater than the second static pressure by a threshold amount.

摘要： A disc-opener implement for use with an agricultural implement includes a disc configured to form a trench in a surface of a field and a scraper adjacent to the disc. The disc-opener implement also includes a knife that is configured to form a furrow next to or into a sidewall of the trench, wherein the knife comprises a leading edge, and a portion of the leading edge is aligned with a trailing edge of the scraper along a lateral axis of the disc-opener implement.
