DEVICE FOR CLASSIFICATION OF CLASSIFIED MATERIAL

摘要

FIELD: devices for classification.;SUBSTANCE: disclosed group of inventions relates to a device for classifying a classified material, preferably into two fractions, preferably earth material, such as sticky (clay) clay material, particularly for use in quarrying. Device for classification of classified material, preferably on two fractions, preferably earthen material, such as sticky, clay earthen material, in particular, provided for use in quarry, has bedplate and at least two installed with possibility of rotation on bed of spiral shaft. At least one spiral shaft has a bearing pipe having at least one outer helical spiral and at least one thrust journal. Bearing tube is elastically installed relative to support journal by means of at least one resilient support means. Spiral shaft is installed with possibility of rotation by means of one support journal with each of both sides. According to the second version of the device on the side of power takeoff there is at least one resilient support device with at least one support post to allow elastic movement of spiral shaft deflection.;EFFECT: technical result is increase in the classification device service life.;13 cl, 14 dwg
