Abstract

See full text

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.
