A particle delivery system of an agricultural row unit includes a particle belt having a particle acceleration section. The particle belt is configured to receive a particle, to accelerate the particle at the particle acceleration section, and to expel the particle toward a trench in soil. The particle delivery system includes a first hub assembly engaged with the particle belt at a first location and a second hub assembly engaged with the particle belt at a second location. The particle acceleration section is disposed generally at the first location, a substantially no-slip condition exists between the first hub assembly and the particle belt at the first location and between the second hub assembly and the particle belt at the second location, and the first hub assembly and the second hub assembly are configured to stretch the particle belt at the particle acceleration section to accelerate the particle.

A method including adjusting a changeable component of a seed planting machine when switching from a first variety of seed to a second variety of seed during planting, wherein the adjusting is based on a location of the planting machine.

A mini-hopper for an agricultural row unit that has a fill tube supplying material to a hopper. A backflow preventer is disposed in the fill tube or in a line to the inlet to prevent flow of material from the mini-hopper through the fill tube when the mini-hopper is in a transport position.

A spreading machine, in particular a precision seed drill, includes at least one seed hopper, at least one fertilizer tank, and a several spreading units. Each of the spreading units includes at least one pneumatically operated separating device to or from which a separation air flow is suppliable or dischargeable and a fertilizer application device. The spreading machine includes a conveying air-driven seed feeding device for providing seed from the seed hopper to the spreading units, and an energy-powered fertilizer supply device for providing fertilizer to the fertilizer application devices. To refine a spreading machine that includes a plurality of consumers, it is provided that the spreading machine includes at least two separate energy suppliers, in particular blowers or pumps, for providing the separation air flows to the separating devices, the conveying air to the seed device, and the energy to the fertilizer supply device.

A mini-hopper for an agricultural row unit that has a fill tube supplying material to a hopper. A backflow preventer is disposed in the fill tube or in a line to the inlet to prevent flow of material from the mini-hopper through the fill tube when the mini-hopper is in a transport position.

Systems, devices, and methods for performing autonomous agricultural operations are described herein. An exemplary device may include a toolbar to which a plurality of implements may be interchangeably coupled, and a pair of parallel chassis beams mounted perpendicularly on the toolbar. At least a portion of each of the chassis beams may be telescopic and configured to be extended outward from, and retracted inward towards, the toolbar. The device may also include a plurality of drive assemblies each mounted on one of the chassis beams, and a plurality of motors corresponding to the drive assemblies and configured to drive the drive assemblies in accordance with one or more drive parameters to move the device throughout a site. The device may further include a computing device configured to automatically determine the drive parameters, and cause the plurality of motors to drive the corresponding drive assemblies in accordance with the drive parameters.

A metering device for an agricultural machine for outputting granular solids out of at least one storage container to at least one dispensing unit by means of, in particular, a pneumatic conveyor system, has a metering housing. The metering housing comprises at least one mounting flange on the storage container-side and/or conveyor system-side as well as at least one inflow opening and at least one discharge opening for the granular solid. The at least one mounting flange is formed as polygon or circular.

In one aspect, a crop input applicator is provided. In one aspect, the applicator comprises a valve (e.g., voice coil valve) disposed to deposit liquid on or near a seed furrow and/or on or near a seed. In one aspect, the applicator includes one or more seed sensors disposed to detect passage of seeds.

The invention relates to a single seed dispenser (10) for a precision automatic sower comprising a cover (11) for seeds to be distributed joined to a body (12) containing a cavity (24) in communication with an aspirator of the seeds via a conduit (22) inserted in a hole (23) realised on the body (12), a distribution disc (13) with holes (38, 54) contained in a compartment delimited by said body (12) and by said cover (11); a driving disc (31) joined through pins (53) to the distribution disc (13), both discs being put into rotation by means of a shaft (29) actuated by an actuator for commanding rotation of the discs (13, 31); and a selector device (14) for the seeds pivoted on the edge of the body (12), where the selector device (14) comprises a plate (142) which presents, on a side facing the centre of the distribution disc (13), at least two toothed portions (143, 144), having teeth of different sizes and a curved sector (59) mounted against the surface of the distribution disc (13) opposite to the plate (142) and is provided with protrusions (591) having inclined surface (592) facing the distribution disc (13) at holes (38) therein.

This document relates to a method and a device for feeding granular material in an agricultural implement and to an agricultural implement comprising such a device. The method comprises providing a take-up zone (102), the extent of which, viewed in a horizontal plane, is defined by a roof (1022, 1026) above the take-up zone, providing side walls (1023, 1027) extending downward from the roof, so that a space (S), which is open in the downward direction and toward an outlet (102b), is formed between the roof (1022, 1026) and the side walls (1023, 1027), providing an airflow (F) through the take-up zone (102) in the direction toward the outlet (102b) from the take-up zone, feeding the material (M) to the take-up zone (102) with the aid of gravity, so that the material falls in a direction transversely to the airflow (F) into the take-up zone (102) and thus delimits the space (S) in the downward direction, providing a part (1022, 1025) which is adjustable between at least two positions, and, with the aid of the adjustable part (1022, 1025), regulating a flow rate of the airflow (F) in a space between the material (M) and the roof (1022, 1026).
