摘要：
The utility model relates to agricultural machinery and is intended for precise sowing of small round-shaped seeds. The universal pneumatic trailed seeder contains a supporting frame on which there are bunkers with two compartments for two types of sown materials, seeding devices, a fan with a drive, and its movement is carried out using undercarriage, which includes pneumatic wheels, a hydraulic system, a system for monitoring the parameters of the seeder, and a transport alarm. At the fan outlet, two branches of the air duct are connected to it through a tee, supplying air to the ejectors of the seeding units and further to the pipelines. The first bend is hermetically connected to the horizontal section of one of the pipelines with the possibility of rotation, to which, in turn, the second bend is also hermetically connected and also rotatably. The first knee and the second knee have independent electric drives for turning relative to the previous structural element, and the control of the independent electric drives is carried out by automation systems. A guide and a vertical pipeline with a wavy inner surface serving as a turbulator are attached to the second elbow. Above, at the end of the vertical section of the pipeline, a distributor is installed, the maintenance of which in the vertical position is carried out by the automation of independent electric drives, while the distributor consists of a body closed from above with a replaceable spherical cover, and a replaceable bottom is installed in the lower part of the body, while the lateral surface of the body is fixed replaceable nozzles, and the replaceable spherical cover has an internal parabolic cone, the surface of which goes to the inner surface of the body, and the replaceable nozzles are funnel-shaped with a taper angle α = 0 ° ... 70 °. In this case, the removable bottom has an opening, in the form of a channel, in the form of a single-cavity hyperboloid, located with an eccentricity (ε = 0 ... 0.1
