FIELD: agriculture.SUBSTANCE: invention relates to agricultural engineering and can be used in drills, mainly for dotted sowing seeds. The pneumatic device for sowing seeds consists of a seed hopper 1, a fan 2, an air duct 3, a depression chamber 4, a sowing disc 5 with openings 6, mounted on the axis 7, an agitator 8, a drive sprocket 9, an adjusting valve 10, a valve of emptying 11, an unloading window 12. And the sowing disc 5 is provided with the magnetic plates 16 overlapping its openings 6, the duct 3 in the lower part is divided into two branches, one of which is brought to the depression chamber 4, and the other is made flexible in the form of vacuum-conveyor 14 and brought to the unloading window 12.EFFECT: this pneumatic device for seeding simplifies the design and increases operational reliability, contributing to the growth of productivity.4 dwg |
