FIELD: agricultural engineering, in particular, precision drilling equipment. ^ SUBSTANCE: seeding unit has hopper, stirrer, dosing device, and drive system. Hopper consists of two departments with discharge windows in their lower part, said departments being connected by means of cylindrical casing. Drum placed within cylindrical casing is connected to drive shaft. Stirrer is mounted on shaft. Seeding disks are also fixed on shaft at both sides of drum. One of seeding disks is equipped with elongated cells wherein adjusting ring is inserted. Other of seeding disks is equipped with through cells. Local slots with shutters are arranged opposite through cells, circumferentially of cylindrical casing. Fertilizer guide is positioned under local slots with shutters. ^ EFFECT: simplified construction and reduced damage to seeds during seeding. ^ 3 cl, 4 dwg |
