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.

Abstract: The distributor comprises a generally cylindrical case which is formed by a housing (1) and a cover (4) between which is rotatively mounted a distributor disk (18) provided with circumferentially spaced-apart orifices (48, 50). Inside the housing, a partition (24) defines a depression passageway (26) in communication with a suction duct (2). The passageway (26) includes a wide upper part (27) in the shape of a crescent which is extended at both ends by a narrow branch (28, 30). Formed in the upper part of the descending branch (30), relative to the direction of rotation of the disk (18), is a cavity (32, 33) for receiving a removable element (34) for isolating this branch from the source of depression. The inner wall of the passageway is provided with an air intake (39) whose opening is adjustable.
