Abstract

Изобретение относитс  к области сельскохоз йственного машиностроени , а именно к устройству вентил торов ветроре- шетной очистки зерноуборочных комбайнов и семеочистительных машин. Цель изобретени  - повышение точности и надежности регулировки величины сокрытых входных окон. Цель достигаетс  тем, что устройство 8 дл  регулировки величины открытых входных отверстий 5 боковых стенок 3 выполнено в виде дисков 9 с отверсти ми 11. установленных с возможностью поворота на боковых стенках 3 корпуса 1 вентил тора , причем величина, форма и расположе-. ние отверстий 11 дисков 9 соответствуют величине, форме и расположению отверстий 5 стенок 3. Механизм поворота 12 выполнен в виде двух зубчатых пластин 13, жестко соединенных между собой стержнем 16, и имеет пружинный рычаг 17, сопр женный с сектором 18, при этом зубь  14 пластин 13 сопр жены с пазами дисков 9. 3 з.п.ф-лы, 5 ил.The invention relates to the field of agricultural mechanical engineering, and in particular, to a device for wind-screen cleaning fans of combine harvesters and seed cleaning machines. The purpose of the invention is to increase the accuracy and reliability of adjusting the size of hidden entrance windows. The goal is achieved in that the device 8 for adjusting the size of the open inlet openings 5 of the side walls 3 is made in the form of disks 9 with openings 11. mounted to rotate on the side walls 3 of the fan housing 1, the size, shape and location of which. the holes 11 of the disks 9 correspond to the size, shape and location of the holes 5 of the walls 3. The rotation mechanism 12 is made in the form of two gear plates 13, rigidly interconnected by a rod 16, and has a spring lever 17 connected to the sector 18, while the tooth 14 plates 13 mating with the grooves of the disks 9. 3 C.p.
