SMALL-SIZED MACHINE FOR DEWINGING, CLEANING AND SORTING OF FOREST CROP SEEDS

摘要

FIELD: agricultural engineering, in particular, equipment for mechanized presowing treatment of forest crop seeds.;SUBSTANCE: dewinging, cleaning and sorting machine has frame and feeding hopper equipped with screw-brush type feeder and mounted on frame. Feeding hopper has upper and lower sections communicated with one another through opening arranged in the vicinity of hopper end wall. Side parts of cylindrical walls of hopper lower section are made netted and composed of two longitudinal sections having meshes of different diameters. Machine has cylindrical dewinger with brush members fixed on shaft equipped with drive. Brush members are made in the form of radial bars with pile bundle holders. Length of holders is equal to length of dewinging. Additional brush members made in the form of radial bars are fixed on shaft. Bars are arranged in helical line.;EFFECT: increased efficiency of machine and reduced damage to seeds.;2 dwg
