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 particulate material sensing and agitation control system of an agricultural system includes an agitator configured to induce movement of particulate material through the agricultural system, a drive system coupled to the agitator, and a sensing system configured to determine a current flowing through the drive system. The drive system is configured to move the agitator, and the drive system is powered via an electrical circuit. The sensing system includes a first input coupled to a first point on the electrical circuit, the sensing system includes a second input coupled to a second point on the electrical circuit, the sensing system is configured to determine a voltage differential between the first point and the second point, and the sensing system is configured to determine current flowing through the electrical circuit based on the voltage differential.

An accumulator is added in-line with a valve on an agricultural machine and downstream of the valve. The valve is controlled to apply liquid material to a field over which the machine is traveling.

An agricultural planting implement is used to plant seed in a field. The implement includes an electrically-driven seed meter that is spaced on a toolbar of the implement. The seed meter, or other metering member, is a precision meter that is used to control the volume, spacing, and location of a seed that is delivered from a meter to the field. A seed source, such as a seed cart or hopper, is attached to the seed meters to provide an on-demand amount of seed to the meters for planting in the field.

A brush belt including a base member having a first side with a traction surface and a second side opposite the first side defining a mounting surface presenting a first edge and a second edge and having a longitudinal axis therebetween and parallel thereto and a plurality of bristles coupled to the mounting surface and arranged in a first section of bristles and a second section of bristles, the bristles of the first section each having a first diameter and the bristles of the second section each having a second diameter that is different than the first diameter. The first section abuts the second section.

A brush belt includes a base member having a drive surface configured to engage a drive member and a mounting surface opposite the drive surface, the mounting surface having a longitudinal axis, a first edge, and second edge, the first edge and the second edge being positioned on opposite sides of the mounting surface and extending parallel to the longitudinal axis, and a plurality of bristles, each bristle having a first end that is proximal to the mounting surface and a second end distal thereto, the second ends of the bristles collectively defining an undulating surface profile relative to the mounting surface when viewed parallel to the mounting surface and perpendicular to the longitudinal axis from either the first edge or the second edge.

A brush belt including a base member having first side with a traction surface and a second side that is opposite the first side, the first side having a mounting surface having a longitudinal axis, a first edge, second edge, and a plurality of projections extending from the mounting surface between the first edge and the second edge, the first edge and second edge of the mounting surface being parallel to the longitudinal axis, and a plurality of bristle clusters coupled to the base member, each bristle cluster of the plurality of bristle clusters having a plurality of bristles and being positioned between two projections.

An apparatus and methods for delivering seed from a metering device to a furrow. In one embodiment, a seed meter entrains seeds on a seed disc rotating toward a seed release location. A guide brush assembly guides the entrained seeds toward the seed release location, whereupon the entrained seeds are released from the seed disc into an upper end of a seed conveyor. The seed conveyor conveys the seed toward the soil and releases the seed with a rearward relative velocity.

A planter includes a plurality of row units. The row units include metering systems, which can include multiple seed meters at a particular row unit, as well as a queuing system. The metering systems including more than one seed meters are configured such that the seed meters will plant a different seed types or varieties. The operation of one or more of the seed meters at a time will provide for the planting of a particular seed variety. The invention provides for on-the-go changing of a seed being planted by changing the operation of one or more of the seed meters at each of the row units and provides for almost infinite variation among the row units for planting particular seed varieties or not planting at all.

A seed delivery apparatus and methods in which a seed conveyor delivers seed from a metering device to a furrow in a controlled manner to maintain seed placement accuracy within the furrow.
