The invention relates to agricultural machinery, particularly to a sowing apparatus of a drum type suction devices. A pneumatic sowing machine of the drum type comprising a fixed hollow axle (1) with an opening (2) for sucking air pipe (3) for connection to a vacuum source, a drum (4) with holes (5) for sucking the outside of seeds mounted on an axle ( 1) rotatably hopper (6) for supplying seeds adjacent the outside of the drum (4) at the border (a) loading seed ekraniruschee device (7) mounted inside the drum (4) on the axle (1) and contacting with the inner surface of the drum (4) and a receiver (8) sown seeds FITTED outside the drum (4) at the boundary (B) discharge seeds. According to the utility model, a screening device (7) is made in the form of evacuating the probe (9) in which one part is fixed on the axle (1) so that its cavity (10) communicates with the cavity (12) of the shaft (1) through the opening (2 ) for air suction, and the other part is in contact with the inner surface of the drum (4) so that the point of contact forms an angular sector (β) of vacuum located between the boundary (a) loading seeds and the edge (B) discharge seeds. Technical result: simplified design of the shielding device, the power source used is reduced vacuum and reduced energy consumption, which enables the use of an improved pneumatic sowing machine mini technique in agricultural facilities, such as a motor-blocks. 1N.
