A pneumomechanical sowing unit comprises a tank with a feeder channel. Said tank is connected with the body, having a working chamber. In said working chamber a vertical sowing disk with cells, which contact the internal cylindrical surface of the body, is mounted. At the surface of the body above an area of feeling the cells a hollow is made. A spacer plate and a cover with a vacuum chamber are pressed to the outer side of the sowing disk. The cells of the sowing disk are made as break-through cuts. On the internal side blades are made, and on the outer side they are partially overlapped by the cover and partially connected with a vacuum chamber thereof by a slit. |
