The invention relates to agricultural machinery, particularly to a sowing apparatus of a drum type suction devices. A pneumatic sowing machine drum comprises a fixed hollow axle (1) with holes (2) for sucking air pipe (3) for connection to a vacuum source, a vacuum drum (4) with holes (5) for sucking the outside of seeds mounted on an axle ( 1) An opportunity of rotation, a hopper (6) for supplying seeds adjacent the outside of the drum (4) in the seed loading zone ekraniruschee device (7) mounted inside the drum (4) on the axle (1), contacting with the inner surface of the drum ( 4) and overlapping openings (5) therein the inside of Seed not reset, and Receiver (8) sown seeds mounted outside the drum (4) in the zone of discharge of seeds. According to the utility model, a screening device (7) is designed as a sliding element (9) which contacts the inner surface of the drum (4) opposite the seed discharge zone and the point of contact forms ekraniruschy angular sector α of the slide member (9) of the shielding device (7 ), which blocks the vacuum and overlaps at least two transverse rows of openings of the drum (4) from the inside. Technical result: simplified design of the shielding device, the vacuum source reduces the power and energy consumption is reduced, which allows improved use pneumatic sowing machine mini technique in agricultural facilities, such as a motor-blocks. 1N. n. f-ly. 4 h. n. f-ly. 6 yl.Полезная модель относится к сельскохозяйственному машиностроению, в частности к высевающим аппаратам барабанного типа с всасывающими устройствами. Пневматический высевающий аппарат барабанного типа содержит неподвижную полую ось (1) с отверстиями (2) для отсоса воздуха и патрубком (3) для соединения с источником разрежения, вакуумный барабан (4) с отверстиями (5) для присасывания снаружи семян, установленный на оси (1) с воможностью вращения, бункер (6) для подачи семян, примыкающий снаружи к барабану (4) в зоне загрузки семян, экранирущее устройство (7), устано
