RUBBING APPARATUS FOR GRASS SEEDS AND VEGETABLES

摘要

FIELD: agricultural engineering. SUBSTANCE: apparatus has planks 6 fixed to base 5 to define Z-shaped surface of contact with longitudinal and transverse channels 8 inclined in different directions. Each row of planks is offset relative to subsequent row of planks for value equal to space between planks. This space is equal to double width of plank 6. EFFECT: increased efficiency, reduced seed loss, improved quality of product and enhanced reliability in operation. 2 cl, 2 dwg
