FIELD: agriculture.
SUBSTANCE: device for single distribution of sowing grains includes drum (10) with cavity (18) made in it. Drum (10) is made with possibility of rotation around axis of rotation. End side of cavity (18) is limited by sowing disk (14), in which several sowing holes (26) are located on imaginary circular trajectory (24) at distance from each other. In cavity (18) body (34) is located, which is made with possibility of rotation around drum located at distance from axis of rotation and parallel to it of its axis. Body (34) with part (34s) of its surface adjoins sowing disc (14) so that when sowing disk (14) is rotating it temporarily seals sowing hole (26) passing from the inner side accordingly. Body (34) is configured to roll over outer cavity (12) outer cavity (18). Pressure spring (21) presses body (34) to side surface (12) in radial direction relative to axis of rotation of drum (10).
EFFECT: invention enables automatic adjustment of the body position and thereby improves functional reliability of the device.
