A pneumatic seed meter for planters is provided which, according to its features, provides a pneumatic meter (1) having a specific mechanical structure integrated in planters and based on a structural fairing (2), two pulleys, an upper pulley (8) and a lower pulley (10), a seed conveyor belt (11) and an electric motor reducer drive (9), aimed at completely optimizing seed dispensing processes directly to the soil by an agricultural planter, the seeds being deposited in a perfectly uniform manner (without gaps or repetitions), together with increased safety and ergonomics for the operators and based on a highly robust, safe and versatile pneumatic meter (1).

An agricultural machine includes a furrow opener and a furrow closing system and a controller that performs closed loop control of the furrow closing system.

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.

A system for planting seeds having a metering system positioned before a belt lowering system that has a sensor to detect the position of a seed on the belt lowering system. The rotational speed of the metering system and the belt lowering system are determined by the speed and location of a planter and the position of the seed on the belt lowering system to correct seed positioning with relation to a pre-mapped or selected field starting location.

A distributing unit (10) for granular material such as seed grains (12), fertilizers or the like is disclosed, in particular a seeding unit (11) of a distributing or seeding machine. The unit (10) comprises a housing (14) with at least one inlet opening (18) for conveying granular material or conveyed seed grains (12) and an outlet opening (26) and also a rotating conveying device (24) with at least one rotating conveying element (28) for taking hold of the granular material or the seed grains (12), which conveying element is arranged or extends approximately axially with respect to the housing (14). The grains are held by centrifugal forces on an inner lateral surface region (16) of the housing (14), are crowded together there and are aligned with respect to one another and are ordered in a line or are rowed at an angle which corresponds to an angular position between the lateral surface and the radial conveying element (28), with the result that in each case only one single grain (12) at the end of the row extends in a predefined path along the lateral surface (16) and, at the end of the separation process, leaves the outlet opening (26) approximately tangentially.

A spreading machine, in particular a precision seed drill, includes at least one seed hopper, at least one fertilizer tank, and 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, 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 feeding device, and the energy to the fertilizer supply device.

A planter for planting seeds in the ground including a seed meter configured to provide a regulated flow of seeds, and a seed conduit defining a first portion of a flow path configured to transport the seeds from the seed meter towards the ground. The planter also includes a seed guide having an aperture in fluid communication with the seed conduit, the seed guide defining a second portion of the flow path configured to transport the seeds from the seed conduit towards the ground, and a shaft configured to reciprocate with respect to the seed guide through a stroke path towards and away from the ground. The shaft is configured to create a discrete hole in the ground for one of the seeds. A side of the shaft is configured to inhibit the one of the seeds from entering the second portion of the flow path until the shaft retracts past the aperture.

An agricultural planter includes a chassis; a pneumatic system carried by the chassis; and a row unit carried by the chassis. The row unit includes: a unit body; a metering unit carried by the unit body and having a port with a channel formed therein; a flexible coupling locked onto the port by an inner lip formed on an inner surface of the coupling, the coupling having a sliding region formed on an outer surface of said coupling; a locking ring bound within the sliding region of the coupling, the locking ring being slidable across the sliding region between a locked position and an unlocked position, the locking ring preventing the coupling from deforming to allow the inner lip off the port in the locked position; and a hose connecting the pneumatic system to the channel of the port through the coupling.

The invention relates to a sowing unit (10) for a precision seeder, comprising: a bracket (12); a tine share (24) arranged on the bracket (12) for producing a placement furrow for grains of seed, which furrow extends in the direction of travel, in the soil of an agricultural area; a separation device (18) arranged on the bracket (12) for separating grains of seed; a placement device (20) arranged on the bracket (12) for placing the grains of seed which have been separated by the separation device (18) into the placement furrow produced by the tine share (24); and a rolling body (26, 36, 38a, 38b) arranged on the bracket (12) for supporting the sowing unit (10) against the soil of the agricultural area and/or for depth guidance of the tine share (24).

An agricultural material ejecting device includes a storage configured to store a granular agricultural material, a discharger configured to discharge the agricultural material from the storage, and an ejector configured to eject the agricultural material from the discharger toward a supply destination. The ejector includes a gas compressor configured to compress gas, and a gas blower configured to blow compressed gas outward. The ejector is configured to eject the agricultural material with use of the gas that the gas blower blows.
