Seed e.g. grain, dosing and separating device for sowing machine, has air intake gap that is formed corresponding to grain quantity, where gap is arranged for seed dosing and separating unit in circumference of unit

摘要

The device has an air intake gap (15) produced by insertion of a plate, when a plate half-shell is positioned against the plate. A seed dosing and separating unit (11) is provided for each sowing tier. An air intake connection is connected with an air suction connection and is attached to an air-low pressure generator that is held up to a grain discharger, where dropping sequence from grain to grain is controlled by an electric motor, and the deposition distance from grain to grain is controlled. The gap formed corresponding to the grain quantity is arranged for the unit in its circumference.
