ПНЕВМАТИЧЕСКОЕ УСТРОЙСТВО ДЛЯ ВЕНТИЛИРОВАНИЯ И ВЫГРУЗКИ ЗЕРНОВЫХ МАТЕРИАЛОВ

摘要

FIELD: pneumatic transportation of grain material. ^ SUBSTANCE: apparatus has transportation pipeline of triangular section, air inlet channel, and charging windows for supplying of grain material into transportation pipeline. Air inlet channel is arranged above transportation pipeline. Equally spaced nozzles are successively positioned in lower part of air inlet channel at an angle toward transportation direction and in spaced relation to transportation pipeline bottom. Flexible valves are fixed on side surfaces of air inlet channel by means of shields providing for adjustment of charging window sizes. ^ EFFECT: reduced consumption of power. ^ 2 dwg
