Design and rationale for parametres of the seed-fertilizer seeder coulter for subsoil broadcast seeding

Abstract For sowing grain crops on stubble, stubble seeders with tine coulters are used, which perform technological operations in one pass. However, they do not meet the requirements of agricultural machinery to ensure an even distribution seeds sub-spear space. The subsoil no-drill planting creates most favorable conditions for growth and development cultivated at same time, crop yields increased average by 10…30%. Using planting, equipped spear spreaders seeding provide best quality distribute evenly over field. article proposes original design seed drill coulter provides feeding area. As a result theoretical researches optimal parameters diffuser determined dependence between unevenness test height pendulum spreader, base diameter obtained. purpose this research is develop rationale use will reduce uneven or mineral fertilizer granules.
