FIELD: agriculture; machine building.SUBSTANCE: seed dispenser comprises hopper, roller-reflector, cellular sowing disc vertically installed in a housing. Latter is composite, where in lateral annular grooves of composite cellular sowing disc there is a solid elastically deformable ring. In centre of outer surface of elastically deformable ring there are hollow thin-walled cylinders made integral with solid elastically deformable ring. Top bases of hollow thin-wall cylinders are part of sphere, convex to axis of rotation of composite cellular sowing disc. Radius of sowing disc is greater than radius of circle drawn at upper bases of hollow thin-wall cylinders of solid elastically deformable ring by 2/3 thickness of sown seeds. Along axis of cells of composite cellular sowing disc at lower base of hollow thin-wall cylinders solid elastically deformable ring is an annular groove whose width is greater than diameter of cells of composite cellular sowing disc.EFFECT: invention enables sowing of seeds of different size without replacement of sowing disc with minimal damage thereof.3 cl, 3 dwg |
