Abstract

FIELD: agriculture and forestry, in particular, single-seed drilling. SUBSTANCE: seeding unit has feeding hopper 1 from which seeds 9 are supplied into upper part of space between drums 4. Space is defined by continuous surface cylinders. While moving over surface of rotating drums 4 and downward, seeds get into lower part of drums 4, where screws with multiple trapezium-shaped thread are positioned. One drum 4 has left-hand thread and other drum 4 has right-hand thread. Thread projections on one drum are inserted into thread slots on other drum. Cylindrical seeding cell is positioned at each thread entry. Seeds are thrown into soil through seeding cells. EFFECT: increased yield of standard seedlings from unit of area of nursery. 2 dwg

The invention relates to agriculture and forestry, and more particularly to sowing devices intended for single-seeding. The task to which the invention is directed is to increase the yield of standard seedlings per unit area of the nursery, which is achieved by single-seeding of seeds in several rows in one row. Seeds from the hopper-feeder are fed into the upper part of the inter-drum space, which is a smooth cylinder. As the drums move along the surface of the rotating drums, the seeds move down and fall into the lower part of the drums, which are screws with multi-start trapezoidal thread, moreover, on one drum the thread is left-handed, on the other - right-handed, and the protrusions of the thread on one drum enter the hollows of the thread on another drum. At each thread setting, a cylindrical sowing cell is made through which the seeds are sown at night.
