FIELD: agriculture.SUBSTANCE: invention relates to agricultural machines for seed cleaning and is designed for final cleaning and isolation of hardly-separated impurities from the base material. The vibro-pneumatic separator comprises a housing provided with a receiving hopper, a vacuum chamber, a divider of fluidised layer, receivers of seed fractions, a direct-flow deck, which is rigidly fixed to the oscillating supports, and drive of the vibro-pneumatic separator. The vibro-pneumatic separator is equipped with two electric motors made in the form of three-phase linear asynchronous motors and the control unit of motors, which input is connected to the three-phase AC network. The electric motors are located opposite the receiving hopper with the ability of linearly progressive motion, at that the secondary element of the motors is a thrust rigidly connected to the housing and located on the drive side. The motor windings are connected to the output of the motor control unit.EFFECT: increased coefficient of efficiency, reliability and performance of the vibro-pneumatic separator is provided.1 dwg |
