  • Patent number: 12213398
    Abstract: The invention relates to a method for detecting the influence of the inclination (?1-?4) of an agricultural spreading device (100, 102) on the distribution of the material to be spread, having the steps of: receiving discharge information on spreading processes of agricultural spreading devices (100) using an analysis device (10) and ascertaining a relationship between a dispensing point of material to be spread onto at least one distribution disc (104, 106, 108, 110) of an agricultural spreading device and the distribution of material to be spread, said relationship depending on the inclination of an agricultural spreading device, using the analysis device on the basis of the received discharge information.

  • Patent number: 12085435
    Abstract: 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.

  • Patent number: 12004505
    Abstract: An agricultural distribution device includes a plurality of spreading elements arranged on a distribution linkage and adapted to spread granular material on an agricultural land, a detection device adapted to detect plant rows on the agricultural land, an adjustment device configured to change an impact area of the granular material dispensed by one or more of the spreading elements on the agricultural land during a spreading process, and a control device which is adapted to control the adjustment device as a function of the plant rows on the agricultural land detected by the detection device during the spreading process.

  • Patent number: 11785882
    Abstract: An agricultural machine for the combined application of seed and granulate on an agricultural area includes a separating device, a portioning device, and a control device. The separating device has a rotationally drivable separating element for separating seed grains and the portioning device has a rotationally drivable portioning element for producing granulate portions. The control device matches the rotational movements of the separating element and the portioning element to each other to implement a predetermined depositing relationship of the seed grains and the granulate portions on the agricultural area.

  • Patent number: 7255050
    Abstract: Pneumatic single grain sowing machine having a seeds storage container, and an individualization device subjected to air pressure, exhibiting perforations and rotating. The individualization device is led with its region disposed below the rotation axis at least in part to the placing of seed grains at the perforations through a seed storage led from the storage container to the individualization device. A separating wall is disposed between the storage container and the individualization device and determining the seed storage height level and extending at a distance to the individualization device in a vertical direction.
