Abstract
Изобретение относитс к сельскохоз йственному машиностроению и может быть использовано дл разделени зерновой смеси сельскохоз йственных культур по аэродинамическим свойствам. Цель изобретени - повышение равномерности воздушного потока по сечению пневмосепарирующего канала (ПСК). Устройство дл регулировани скорости воздушного потока установлено в ПСК, соединенном с нагнетательным патрубком диаметрального вентил тора и имеющем питатель и приемники обработанного материала. Устройство содержит заслонку, выполненную в виде установленных друг под другом и примыкающих друг к другу перфорированных пластин (ПП) 6, 7, 8. Верхн ПП 6 установлена неподвижно, ПП 7 и 8 - с возможностью независимого фиксированного продольного перемещени . Поперечные кромки заслонки загнуты в разные стороны, а площадь перфорации возрастает от одной поперечной кромки к другой. При подаче обрабатываемого материала равномерно по глубине ПСК создание необходимого равномерного спектра скоростей воздуха по глубине канала производитс поворотом заслонки с совмещенными ПП 6, 7, 8. Затем постепенно перекрывают эти перфорации одновременным равномерным перемещением ПП 7 и 8 относительно ПП 6. 4 ил.The invention relates to agricultural machinery and can be used to separate the cereal mixture of agricultural crops by aerodynamic properties. The purpose of the invention is to improve the uniformity of the air flow over the cross section of the pneumo-separating channel (PSK). A device for controlling the speed of the air flow is installed in the UCS, connected to the discharge pipe of the diametrical fan and having a feeder and receivers of the processed material. The device contains a flap made in the form of perforated plates (PP) 6, 7, 8 installed one above the other and adjacent to each other. The upper PP 6 is fixed, PP 7 and 8 - with the possibility of independent fixed longitudinal movement. The transverse edges of the flap are bent in different directions, and the area of perforation increases from one transverse edge to another. When feeding the processed material evenly over the depth of the UCS, creating the required uniform spectrum of air velocities over the channel depth is performed by turning the shutter with the combined PC 6, 7, 8. Then gradually overlap these perforations by simultaneously uniform moving the PC 7 and 8 relative to the PC 6. 4 Il.
