A distribution device for granular material having: a distributor housing which has a material inlet opening for the granular material; at least one conveying air duct, situated in the distributor housing, for a material-free conveying air flow, the conveying air duct being connected within the distributor housing to a grain-holding region within which the granular material entering the distributor housing via the material inlet opening can be introduced into the material-free conveying air flow; one or more material flow lines, which adjoin the grain-holding region, for the conveying air flow laden with granular material; and at least one additional air duct, which is situated in the distributor housing for a material-free additional air flow, which can be introduced into the one or more material flow lines via at least one additional air inlet.

Distribution device for granular material

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.

Spreading machine

A sowing machine and a method for separating and spreading granular material, such as seed or the like, are described, where the material is supplied by way of conveying airflows from a central container to metering devices via conveying ducts respectively associated with them. Furthermore, the material supplied in the conveying ducts is separated from the respective conveying airflow and the resulting discharge airflows are supplied via discharge air ducts to the respectively associated metering devices which are thus pressurized. Furthermore, the metering chambers are pressurized by way of supply airflows via supply ducts respectively associated with the former. The material is separated in the metering chambers by way of separating disks.

A material introduction lock for a distribution machine for pneumatically conveying granular material in a conveying line adjoining a material introduction lock includes: an air inlet, a material conveying element, and a material infeed element, where a pneumatic conveying flow is supplied to the material conveying element via the air inlet, and the material infeed element is arranged between the material conveying element and the conveying line so that the granular material in the conveying line supplied via the material infeed element is conveyed in the conveying line by the pneumatic conveying flow supplied by the material conveying element. Further, the material infeed element includes a rinsing nozzle element which is connected to the air inlet and creates a film of air that sheathes the material infeed element from the inside, and the rinsing nozzle element is configured to reduce contact between the granular material and the material infeed element.

A pneumatic distribution machine for granular material includes a storage container, a delivery fan for generating a main air/material flow, and a distributor head configured to divide the main air/material flow fed to the distributor head into multiple individual air/material flows, a long main delivery line connecting the delivery fan, the storage container, and the distributor head, and a return device that includes a movable deflection element that is configured, in a dispensing position, to feed an individual air/material flow flowing into and inflow region of the return device to a dispensing region, connected to a dispensing line, of the return device, and in a shut-off position, to feed an individual air/material flow flowing into the inflow region of the return device to a return region that is connected to a return line of the return device.

Pneumatic distribution machine

A portioning device for chemical granular material, in particular fertilizer, having an inlet opening for granules, an outlet opening for discharging granule portions produced from the granules and at least one rotationally drivable conveying element which is designed to combine granules fed to the portioning device to give granule portions during a rotational movement.

Portioning device for chemical granular material

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

A pneumatic single-grain sowing machine includes: a closed housing; a rotatably driven separating device, which has circularly arranged perforations; and a fan for producing a pressure difference between the housing and the interior of the separating device, the separating device thus being designed to separate seed by use of the perforations with the aid of the pressure difference, the separating device being designed as a closed hollow drum having two side walls arranged at a distance from each other. The separating device is designed to compensate slight housing expansions.
