VORRICHTUNG ZUR VEREINZELTEN ABGABE VON SAATKÖRNERN

摘要

The device has a drum (10) rotating about an axis of rotation and containing a hollow chamber (18) connected to a vacuum source. One end of the hollow chamber is defined by a sowing plate (14) having several suction holes (26) arranged a distance apart along an imaginary circular path. A body (34) arranged in the hollow chamber rotates about an axis arranged a distance from and parallel to the axis of rotation of the drum and lies with one part (34s) of its surface against the sowing plate so that when the sowing plate rotates a hole passing by is temporarily blocked on the inner side. Preferred Features: The body rotates about a stationary axis and is pressed against the sowing plate. The body has rotational symmetry and is in the form of a plate made of plastic or rubber.
