INSTALLATION FOR PROCESSING SURFACE OF ARTICLES MADE FROM CONCRETE MIXES Russian patent published in 1994 - IPC

FIELD: production of prefabricated concrete and reinforced concrete. SUBSTANCE: installation comprises carriage with end brushes, and cylindrical brushes. End and cylindrical brushes are provided with their hold-down and withdrawal mechanisms. Each cylindrical brush is connected with drive shaft by coaxially-positioned coil springs and is capable of radial and axial movements. Cylindrical brush may have a vibration-generating mechanism in the form of ball stops interacting with projections and connected fixedly with body of bearing support. Drive shafts of cylindrical brushes may be of eccentric design. Cylindrical brushes may be coupled with the drive across a single-stage planetary reduction unit. Each brush is so designed that the profile of its projection on a plane perpendicular to shaft has the form of a triangle with convex sides. Oscillating motion of cylindrical brush enhances its activity in the zone of contact with processed surface which contributes to high-quality cleaning of articles. EFFECT: improved design. 4 cl, 13 dwg
