Pavelchyk Y. The investigation and improving ploughs for grain-crops sowing underground scattered method

In the Doctorial thesis were observed scientific technical literature qvestions of the grain-crop sowing underground scattered method, the working organ construction of seeder for grain-crops sowing underground scattered method, the research analysis of distributive organ means work was done. On the theoretical basis of the seeds distribution investigation process by underground- scattered sowing method was fixed seed speed falling to the reflector, the theoretical substantiated parameters of seed reflector prism, and the technological plans of distributive ploughs means in underground-scattered seeding machines were elaborated. The influence means of seed sowing was fixed, the seeds types flowing distribution and seed reflector the regularity of seeds distribution on the nourishment area. The using of surgested working organ will give possibility to get seeds, putting 90% of seeds in three connecting horizons. While the disk ploughs have only 56% seeds in three connecting horizons. Per year economic effect using one experimental seeder is 11968 grn in comparing with seeder SZ- 3,6.
