FIELD: agriculture. ^ SUBSTANCE: seed dispenser comprises a hopper for seeds and a working element in the form of a tube, which makes reciprocal movements along the radius and oscillating movements along the circumference by means of a drive from the seeding machine running wheel. The drive is arranged in the form of a linear induction motor with a stator that embraces a rotor. At the same time the tube represents a motor rotor. Elastic elements are rigidly installed on the rotor, and the stator is installed between them. The stator is installed as movable relative to its centre of gravity and is equipped with a control unit with position sensors at the seeding machine running wheel. ^ EFFECT: invention is efficient in operation and provides for the possibility to adjust seeding rates. ^ 3 dwg |
