A seed meter is provided for planting multiple types of seed and rapidly switching between the types being planted in a single planting pass of a planting session of row-crop planting. The seed meter has a split seed meter reservoir with a pair of seed meter chambers flanked by or next to a pair of seed disks. Activation and deactivation of the seed disks within the seed meter are synchronized to selectively deliver one type of seed from one of the seed meter chambers for delivery out of a single seed tube of the seed meter, which may provide absolute and instantaneous on-the-go seed switching within a single row from each seed meter.

A meter roller for an agricultural metering system includes multiple flutes and corresponding recesses. The flutes and the corresponding recesses are configured to meter flowable particulate material from a storage tank to a material distribution system via rotation of the meter roller. The meter roller also includes multiple air passages formed within a body of the meter roller. Each air passage is fluidly coupled to a central cavity of the meter roller and extends to a base of a respective recess, and the air passage is configured to flow air from the central cavity into the respective recess.

One or more techniques and/or systems are disclosed for metering assembly for an agricultural seeder. The metering assembly can be configured for quick and easy removal and replacement, where merely the assembly is removed without disassembling other parts of the seeder system. An improved coupler, in conjunction with a threaded knob device, allows for quick and easy access to the assembly, for removal and replacement in a metering tube. A visual indicator can be disposed on the end of a rotating shaft to provide a user with a quick confirmation that the assembly is properly rotating during operation.

The invention relates to a metering device (5) for granular material, in particular seeds and/or fertilizer, where the metering device (5) comprises a metering housing (9) having at least one inlet (8) and at least one outlet (11) for the granular material and two side walls (10) that are arranged spaced from one another, where a metering wheel (13) with end faces (13a) each pointing toward the side walls (10) is arranged between, firstly, the inlet (8) and, secondly, the outlet (11), and between the side walls (10), that are arranged spaced from one another, on a shaft and is connectable in a force-fit manner to the latter and can be driven to rotate by the shaft in a metering direction (D), where the metering wheel (13) is associated with blocking means (14) which are configured to block the metering wheel (13) against the transport of granular material in a direction opposite to the metering direction (D) from the inlet (8) to the outlet (11) and/or in the metering direction (D) from the outlet (11) to the inlet (8), and a plain wheel (15) is arranged at each end face (13a) of the metering wheel (13) and extends between the end face (13a) and the side wall (10) in an unfastened manner on the shaft, where a sealing element (16) is arranged on both sides between the respective end face (13a) of the metering wheel (13) and a side surface (15a) of the respective plain wheel (15) pointing toward this end face (13a).

A seed meter for metering a plurality of seeds includes a seed meter housing defining a seed inlet, a seed outlet, and a chamber therebetween, a hub rotatably mounted to the seed meter housing about a rotational axis and extending from a first end positioned within the chamber of the seed meter housing to a second end positioned outside of the seed meter housing, a metering element mounted to the hub within the chamber, a plurality of drain apertures located in the seed meter housing adjacent to the hub, and a handle mounted to the second end of the hub, the handle extends over the plurality of drain apertures in an axial direction parallel to the rotational axis of the hub.

Modular meter units for distributing particulate material from an applicator can be configured to combine with each other without the use of tools to provide specific meter assembly lengths based on desired flow rates. In one aspect, modular meter unit housings with interlocking features can provide build options for assembling different sized meter assemblies. The modular meter unit housings can allow stacking and connecting multiple adjacent meter units to make a meter assembly of a particular length/volume/flow rate. Each meter unit housing can have a longitudinal bore that opens through opposing end walls and define a cylindrical cavity or chamber that can receive a cylindrical/tubular sleeve or liner. Matching openings on opposite top/bottom walls of the modular meter unit housing can align with openings of the liner to define an inlet and outlet for the meter unit.

Agricultural implement assembly, for the rapid transformation of a seed drill with a drilling or dragging dosing device, volumetric supplier to an on-demand supplier and vice versa, including at least one hopper containing a granular input, such as grains, seeds or granules of agrochemicals, and a delivery device arranged under the hopper. This device has a structure consisting of two physically delimited areas. A seed box is formed by side walls that delimit its width, a bottom wall, a rear wall with the air inlet from the fan, and a front partition that has at least the passage of the seed to the area where the dragging rotor is eventually located for the case of drilling work, or to the area where the containment slope is located for the case of on-demand supply.

The invention relates to an agricultural tool unit for the rapid conversion of a seed drill having a trailed or fine-grain seed dispenser with volumetric supply to an on-demand supply system and vice versa, which includes at least one hopper containing a granular feed material, such as grains, seeds or agrochemical granules, and a delivery device arranged under the hopper. This device has a structure that consists of two physically defined areas. One of the areas, hereinafter referred to as the “seed box”, has a direct connection to the hopper, receiving the granular material from same, generally gravity-fed, and another area, hereinafter referred to as the “air box”, which has a connection to an air source such as a fan or similar. The seed box is formed by side walls that define its width, a lower bottom wall, a rear wall with the air inlet from the fan, and a front wall that comprises at least the passage for the seed leading to the area where the trailing rotor is located for fine-grain work, or to the area where the retaining slope is located for on-demand supply.

A bearing end cap for a modular meter assembly for distributing particulate material from an applicator can include recesses that accommodate locking tabs or fingers of modular meter unit housings and protrusions that lock a meter tube against rotation. In one aspect, a bearing end cap can be provided with a particular construction that cooperates with modular meter unit housings. The bearing end cap can have vertical and horizontal symmetry and cutouts near its corners. These cutouts can provide clearances to accommodate the locking tabs or fingers of modular meter unit housing end walls. Back walls of the bearing end caps can have protrusions that extend into end cutouts of a tube which defines an interior perimeter of the meter assembly.

A tubular sleeve for a modular meter system for distributing particulate material from an applicator can be inserted through a meter assembly that is built from modular meter unit housings to define the boundary wall of a meter cavity and provide internal structural support for the meter assembly. The tube can be provided with inlet and outlet openings that can be inserted through modular meter housings to form an overall meter assembly of a particular length and therefore volume/flow rate. In one aspect, a tube or tubular sleeve can be inserted into a stack of connected meter units while assembling a modular meter assembly. A circumferential sidewall of the tube can have pairs of oppositely positioned openings that provide inlets and outlets for a meter assembly.
