CENTRIFUGAL SIEVE SEPARATOR Russian patent published in 2021 - IPC B07B1/26 B07B9/00 

FIELD: agricultural engineering.

SUBSTANCE: proposed invention relates to agricultural engineering and is intended for the separation of grain mixtures. The centrifugal sieve separator includes a loading neck, a drive and a cylindrical body, in which a conical shell, a feeder, a block of cylindrical sieves with a brush, a conical dividing sieve, a plate drum, an unloading pipe of purified grain, a pipe for removing light and small impurities are placed on the drive shaft. The separator contains an additional cylindrical body with an aspiration system placed in it and air intake windows, with a diameter equal to the diameter of the main cylindrical body. The aspiration system includes an annular pneumatic separation channel, a conical spreader, a conical reflector equipped with an adjustment cup. An additional cylindrical body of the aspiration system is placed between the loading neck and the shell. The drive of the equipment of the aspiration system is carried out from a conical shell. The adjusting cup is made with the possibility of moving it along the vertical axis of the conical reflector. The height of the adjusting cup is less than the cylindrical part of the conical reflector on which it is installed.

EFFECT: increased efficiency of cleaning grain from light impurities and simplifying the design.
