DEVICE FOR SEPARATION OF SEEDS ACCORDING TO ELASTICITY Russian patent published in 2017 - IPC B07B13/00 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for separating bulk particulates of materials according to elastic properties and can be used in agriculture in purification of particulates of seed material. Device for separation of seeds according to elasticity comprises a loading and unloading hopper-dispenser with an outlet slit, steps of working bodies disposed one under the other, comprising a reflective element in the form of a truncated cone located with its large base downwards, a divider. The separator has an inner and an outer cylindrical channels. The loading and unloading hopper-dispenser has a conical feeder made in the form of a large cone located with its large base downwards, with the ability of its movement in height. The steps of the working bodies are located in an internal cylindrical channel and contain a successive conical guide formed as a corrugated truncated cone located with its large base downwards with the ability of its movement in height, a reflective element, and a funnel-shaped divider the lower part of which with an outlet annular slit is located above the conical guide below the located step. In the focal line zone of the reflective surface a slit receiving box of elastic particles is located, formed by the upper annular edge of the funnel-shaped divider and a wall of the inner cylindrical channel. The working parts of each step are made with different radial dimensions decreasing sequentially from step to step.

EFFECT: increased performance and efficiency of separation is provided.
