Abstract
Apparatus for introducing discrete seeds or clusters of two or more seeds into each of an array of seed carrying devices at a seed inserting station has a rotary drum-shaped conveyor whose shell has rows of axially parallel suction ports. Such rows form several groups each containing ports of a particular size. The rows travel past a magazine which contains a supply of seeds and from which selected rows draw seeds which remain in the respective suction ports during transport to the inserting station. To this end, the selected rows are connected to a suction generating device by way of channels which are provided in the shell. The component which determines whether a single group or two or more groups of rows are to be connected with the suction generating device is a ring-shaped selector which is rotatable with reference to the shell and has two or more sets of openings which can be moved into or out of alignment with the channels in the shell. The conveyor can be turned relative to its drive shaft in order to select a particular single group of rows for transfer of seeds from the magazine to the inserting station.
