FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine building. Device for separation of grain hay heap comprises feeder, conical spreader, fan and receiving chambers for collecting fractions. Feeder is made up of funnel-shaped bin with outlet slit and annular proportioner. Conical spreader is installed under annular proportioner on vertical shaft with possibility to rotate and move vertically. On surface of spreader straight blades are installed perpendicularly. Under spreader there is device in form of cone for air flow direction. Injector nozzle of fan is installed across trajectory of particles of heap from feeder. Receiving chambers for collecting fractions are composed of circular funnel shaped sedimentary chambers.
EFFECT: device for separation of grain hay heap has high output and efficiency of separation of initial mixture of output components.
