ABSTRACT:
Distributor for a seed spacing drill, including a casing having an overall cylindrical shape, inside of which a flat distributor disc is rotatably mounted. The disc is equipped with circumferentially-spaced holes which have dimensions smaller than the seeds to be distributed. The distributor disc separates a seed container from a auction device so that the holes are subjected to a depression for retaining the seeds taken up from the container during at least a part of their angular travel. A deflector member is provided to eliminate double seeds. A device is provided for discharging the seeds. The distributor disc includes at least two coaxial circular rows of holes which are subjected to the suction or depression until the holes register with the discharge device. The deflector is located, relative to the said distributor disc, so as to act only on the seeds located in the holes of the outermost or the innermost row.
