FIELD: agriculture.SUBSTANCE: invention relates to devices for separation of loose materials based on elasticity and can be used in agriculture, chemical and construction industries. Device for separation of seeds comprises housing, loading-unloading station, located in housing one above other stages of working elements, each said stage comprises series-arranged funnel grain surface, funnel-shaped feeder, reflecting element in form of truncated cone larger base directed downward, fraction receivers. In every stage under slope surface there is conical guide. Under funnel-shaped feeder is installed an acceleration section made in form of a perforated truncated cone with larger base directed downwards. Conical guide, acceleration section and reflecting element may displace in guides secured to vertical shaft. Inclined surface, conical guide and funnel-shaped feeder are used for loading-unloading of receiver. Under loading-unloading receiver there are inner and outer cylindrical conveying channels. Stage of working elements are arranged inside transfer channel.EFFECT: technical result is increase in productivity and efficiency of separation.2 cl, 1 dwg |
