DEVICE FOR SEED SEPARATION ON ELASTICITY Russian patent published in 2015 - IPC B07B13/00 

FIELD: agriculture.

SUBSTANCE: device of seed separation on elasticity comprises a loading-unloading receiver, a funnel-shaped feeder, under which the steps of working elements are located one under the other, made with the ability of movement and fixing of their position on the guide extending along the axis of the device housing, each step of the working elements comprises a reflective surface in the form of a truncated cone located with the large base downwards, a funnel-shaped chute board with a discharge slit. The loading-unloading receiver is provided with a conical guide fixed on the axial guide of the housing and the funnel-shaped feeder located under it. Each step of the working elements comprises a boost part, a reflective surface, mounted in sequence, rigidly connected to the separating surface, mounted in the cylindrical receiver, made integrally with the funnel-shaped chute board with a discharge slit. The boost part is located between the funnel-shaped feeder and the separating surface and has a curved corrugated surface consisting of a conical surface extending into a surface in the form of a truncated cone, mounted with the large base downwards, the boost part with its apex of the conical surface is fixed on the guide extending along the axis of the device housing, under the funnel-shaped feeder, the separating surface is made in the form of a truncated cone located with its larger base downwards, which generatrix is parallel to the generatrix of the cone of the reflective surface.

EFFECT: increase in efficiency of separation of bulk materials on properties of elasticity and a decrease in damage of grain germs.
