摘要：
The invention is related to agricultural machinery engineering, in particular, to pneumatic seeding machines for sowing loose materials. The objective of the proposed invention is reduction of non-uniformity in distributing seed material of different crops to shoes and lower seed damage. The pneumatic-dispenser seeding machine that attains this objective comprises a vertical pipeline having an arc-shaped air duct connected to its bottom cross-section and a dividing head with seed drill tubes connected to its top cross-section, wherein a cover fixed on the dividing head is made of a transparent material in a semi-sphere shape and has a mark for visual control of aerodynamics, centering and turbulization of air-material mixture, and the dividing head has channels mounted on a shaft at the inlet of each channel is a freely rotatable plate having a surface of elastic material and marks for visual control of aerodynamics, and a similar plate is mounted on a shaft at the outlet of each channel, the angle of rotation of the latter plate is adjusted by a screw and is selected so that rotation angles of the first plates of all dividing head channels under effect of dynamic pressure of air-material mixture as determined from the marks are equal, coincident with the mark on the cover. The advantage of the proposed invention is that it improves uniformity of seed material distribution between shoes in accordance with agronomic requirements and provides the possibility of its correction (adjustment) for seeding of different crops by seeding machines with pneumatic dispensers and centralized dosing it reduces also seed damage, which increases yield of agricultural crops.Изобретение относится к сельскохозяйственному машиностроению, в частности к пневматическим сеялкам для высева сыпучих материалов.
