FIELD: agricultural industry. ^ SUBSTANCE: outfit consists of a tractor, soil-treatment working members, a packer wheel, and a sowing machine. Tractor is equipped with front and rear mountings. To the front mounting there hinged is a cultivator so that it can turn. Cultivator has soil-treatment working members made in the form of cultivator teeth and installed at the depth twice as bigger than the depth of sowing area. After the teeth at the same depth there installed are applicators. Cultivator teeth and applicators are installed in a staggered order as the outfit advances in order to symmetrically distribute the load. Cultivator is equipped with cans intended for fertilisers, the outlet hoppers of which are provided with double-flow distributors with fertiliser tubes rigidly attached to them. On the rear mounting there installed is an automatic coupling. On the latter there rigidly fixed is a frame with a vibration harrow, a wheel, a sowing machine, and a tailing device. Vibration harrow is hinged to the frame with the possibility of back-and-forth motion from a crank-and-rod mechanism driven from the tractor power takeoff shaft. Wheel is water-filled and is provided with grousers. The latter are made in the form of sections of angles installed rigidly and symmetrically along the wheel surface with equal pitches both along the wheel and in its circumferential direction. Pitch of grousers along the wheel is equal to their length. Each following row of grousers in the circumferential direction of the wheel is offset half of circular pitch relative to the preceding row. Seed-sowing outfit drive of seeding machine is made in the form of a chain gear from packer wheel. Tailing device is made of chain string in the form of sine curve or cosine curve. The string on each side is rigidly attached with straight links to the frame, and to arc-shaped brackets at bend points. Arc-shaped brackets are rigidly attached to the frame so that they can be removed. Socks are installed in line with applicators and equal to their number. ^ EFFECT: improving the quality of soil treatment and sowing, and arranging conditions required for plant growth and development. ^ 5 dwg |
