A grain-singulating apparatus comprising, a metering chamber and a singulating disk arranged therein, at least one supply duct for feeding a singulating air flow generated by a blower into said metering chamber for the singulation of grains by way of said singulating disk, a conveying duct for supplying the grains stored in the storage container, in the form of a mixed grain/air flow generated by the blower, and a separating device for the separation of the grains from said mixed grain/air flow and for providing them via a seed chute to said singulating disk for singulation and for feeding the resulting extracted air flow via an extracted air duct separate from said supply duct to said grain-singulating apparatus for the singulation of the grains.

A seed meter includes a meter housing having a first chamber for seeds and a second chamber. A seed disk is rotatably supported within the meter housing and has a first side and a second side. The first side is exposed to the first chamber and the second side is exposed to the second chamber. The seed disk includes a plurality of seed openings that extend between the first and second sides at a predetermined radial position. A singulator is positioned against the first side of the seed disk and has at least one structure for removing excess seeds from the seed openings as the seed meter disk rotates relative to the singulator. A radial position of the singulator is controlled at least in part by a hub portion of the seed meter. A biasing spring is positioned to exert an axially-oriented bias force pressing the singulator against the first side of the seed meter disk.

A seed metering system for metering a plurality of seeds includes a meter housing having a front side and a rear side opposite and attached to the front side, a seed inlet defined within the front side of the meter housing, and a seed disk positioned within and rotatable relative to the meter housing. The seed disk has a first side in facing relation to the front side of the meter housing and a second side in facing relation to the rear side of the meter housing. The seed metering system further includes a seal in contact with the front side of the meter housing and the first side of the seed disk.

A seed sensor includes a housing. An internal seed channel defines a path for seeds to flow along a central axis through the seed sensor. A sensor unit is positioned alongside the internal seed channel within the housing. An inlet end of the seed sensor includes a tapered inlet section. The housing includes a mounting loop having a pair of oppositely angled surfaces for mounting the seed sensor in a pair of oppositely angled configurations.

A seed metering system for metering a plurality of seeds includes a meter housing having a first side and a second side. A seed inlet is positioned at the first side and an aperture is positioned at the second side. The seed metering system further includes a hub mounted within the aperture, a retaining member located at the hub, and a metering member positioned on the hub. The metering member compressively engages the retaining member.

A seed meter disk includes a body defining a plane of rotation. A circumferential array of seed openings are provided for seed adherence. A circumferential array of seed agitator pockets are formed as depressions in the first side of the body, each one of the array of seed agitator pockets having a radially inner end, a radially outer end, and a trailing edge extending from the radially inner end to the radially outer end. At least a portion of the trailing edge of one or more of the seed agitator pockets is backswept so that a circumferential-direction offset from a radial reference line rotationally ahead of the trailing edge, with respect to rotation of the seed meter disk in an operational direction, increases toward the radially outer end. The backswept portion is non-linear.

A seed meter for metering a plurality of seeds includes a seed disk housing having a seed inlet, a seed outlet, and a chamber therebetween, a seed disk mounted within the chamber of the seed disk housing, a motor having an output shaft and a gear mounted thereon, the gear being engageable with the seed disk and operable to rotate the seed disk relative to the seed disk housing, a mount fixed relative to the motor, the mount having a non-planar engagement surface, and a hook attached to the seed disk housing, the hook having a non-planar engagement surface engageable with the engagement surface of the mount.

A seed receptacle includes a housing defining a seed chamber within, a seed inlet formed in the housing, a seed outlet formed in the housing, and an air inlet separate from the seed inlet and mounted to the housing. The air inlet includes a first end attached to the housing and defining a first aperture, a second end, opposite the first end and defining a second aperture, and a channel defining an airflow path between the first end and the second end. The air inlet has an elasticity and a weight such that the second end sags relative to the first end.

A dual-disk seed meter for a planter may include a housing defining a first seed chamber configured to receive first seeds of a first seed type and a second seed chamber configured to receive second seeds of a second seed type. The seed meter may also include a first seed disk rotatable within the housing to convey the first seeds from the first seed chamber, a second seed disk rotatable within the housing to convey the second seeds from the second seed chamber, and a drive assembly configured to simultaneously rotate the first and second seed disks. In addition, the seed meter may include a seed deflector movable relative to the first seed disk and/or the second seed disk to control which of the seed types is discharged from the housing based on a selected seed type to be delivered by the seed meter.
