Makarenko D. Increasing in service life of sowing complexes’ parallelogram mechanism by changing construction of movable connections

In the dissertation an assignment on increasing in service life of sowing complexes’ parallelogram mechanism by changing construction of movable connections with applying polymeric and composite material was solved. In the work the main parameters of movable connection elements of parallelogram copying mechanism were determined in the condition of dynamic interference of seeding sections’ tyne coulters with ground. Investigation of features and characteristics of copying mechanism’s movable connections based on polymeric and composite materials was conducted. The wisdom of implementing the polymeric and composite materials into movable units had been proved. The main results of work realized in holding «Агро-Союз», Dnipropetrovs’k region, it was accepted to implement developed details into mass production of sowing complexes Агро-Союз Turbosem II 19-60.
