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. In order to furnish a single grain sowing machine wherein the part segments with thereon disposed storage containers and individualization devices can be pivoted by 90 degrees around the horizontally running swivel axis, an adjustably formed blocking device is disposed between the individualization device and the separating wall in the region of the lower end of the separating wall and above the seed storage height level, wherein the blocking device closes in the intermediate space between the individualization device and the separating wall.
