Substantiation of the technological scheme of pneumatic grain seeder of subsurface dense sowing

Abstract

The article describes the shortcomings of existing structures and units of pneumatic grain seeders. There was analyzed the technological process of distribution of seed material in distribution systems. There were described the various options of developed designs of dosing and distributive systems allowing to increase the sowing machines efficiency. To improve the efficiency of sowing machines, it is proposed to establish a distribution of seeds with a downward flow, which will increase the uniformity of seed supply to coulters and, consequently, increase the uniformity of their distribution over the field surface.
