Single disc coulter with gauge wheel for pneumatic seed drill

Abstract

Abstract The production of competitive, ecological agricultural products by agricultural producers in modern conditions is impossible without the modern equipment that provides a combination of technological operations in sowing and fertilizing. As a result of an analytical review of modern coulter designs used in modern seed devices for sowing, planting seeds of grain crops and granules of mineral fertilizers during their application, it was found that the most efficient single disc coulters with press wheels used as gauge-wheels, which ensure high-quality grain crops sowing. The design of the coulter with a gauge wheel of the pneumatic seeder has been developed and its design parameters have been determined. The conducted laboratory field tests of a pneumatic seeder equipped with experimental coulters with a gauge wheel made it possible to determine its optimal design parameters: coulter disc diameter 0.4 m, diameter and width of the copying wheel - 0.27 m and 0.04 m, taking into account the standard deviation of the distribution of seeds at the depth of planting.
