Improvement Dynamics in the Design of GroovedRoller Sowing Device

Abstract

The article considers some constructive developments of the grooved-roller sowing devices for the re-equipment of cereal crop seeding - machines. The recommended universal sowing unit enables to provide high sowing  quality of the seeds of various crops, promotes seed saving, low cost price, as well as an increase in the annual loading of the device and a reduction in its exploitation costs. The article also indicates possible directions for further design improvements: increase in the universality
level, improvement of sowing uniformity, stability of the sowing technological process regardless of the terrain relief, possibility of differentiated sowing with optimal parameters, etc.
