APPARATUS FOR CLEANING MILL SIEVES (VERSIONS) Russian patent published in 2001 - IPC

FIELD: milling equipment. SUBSTANCE: apparatus has cleaner made in the form of n-shaped plate with flat fabric brushes spring-loaded to sieves by means of flat springs, central tray mounted for free rotation about shaft with spherical end. Ratchet belt mounted on inner diameter of housing has teeth which are in contact with free ends of spring-loaded rods mounted in clips on carrier edges. Inertia mass is fixed to one side of clip. According to other version, carrier brushes are made in the form of n-shaped plate with inertia mass on one side and equipped with hair bristles inclined with respect to sieve and arranged at equal pitch on each carrier side. Bristles on one brush are positioned in gaps between bristles on other brush. Brushes are mounted for sliding on sieve surface to be cleaned during rotation of carrier, on support similar to first version in one direction and abutting against sieve meshes during rotation in opposite direction. Inertia mass may have supporting rollers. According to second version, magnetic vibrator with strikers may be used as inertia mass. Strikers periodically come into engagement with sieve. EFFECT: enhanced reliability in operation and reduced noise level. 7 cl, 12 dwg
