FIELD: machine building.
SUBSTANCE: invention relates to a pneumatic seeder comprising actuators acting on at least a sealing device and a fixing wheel to adjust a certain pressing force for at least a sealing device and an embedding wheel. According to the invention, the sowing device comprises a bearing lever having a first and a second part branched therefrom. Carrying lever of the sealing device by the first end is pivotally connected by means of the first axis to the specified second part of the bearing lever and the second end is connected to the sealing device. Actuating mechanism of the sealing device by its first end is pivotally connected by means of the second axis to the second part of the bearing lever, and by the second end it is connected to the bearing lever of the sealing device. Actuating mechanism of the sealing device or setting device is a hydraulic cylinder, or a pneumatic cylinder, or a lever mechanism with electric drive.
EFFECT: invention will make it possible to improve quality of seeds sealing in a furrow.
