FIELD: agriculture. ^ SUBSTANCE: device includes a sowing apparatus, a tubular stand-seed duct, an active scatterer. A working coil of the sowing apparatus is formed by trapezoidal blades set at the angle of 30Ç35 to the plane of rotation. Adjacent blades of the coil are inclined to different sides. The sowing coil is placed in the box with a semi-cylindrical bottom. The box is installed with the possibility of rotation to different sides into a semi-cylindrical base, which is rigidly fixed at the end of the tubular stand-seed duct. At the same time at the bottom of the box and the base there are diamond-shaped holes for passage of seeds. ^ EFFECT: apparatus has simplified design and makes it possible to ensure stable movement of fine seeds slow in the seed duct at low controlled norms of sowing. ^ 2 cl, 2 dwg |
