Substantiation of the parameters of the double flat disc seeder for directly sowing repeated crops in the soil after wheat crop harvesting in Uzbekistan

Abstract

The article presents the results of theoretical studies on the basis of the parameters of a seeder equipped with a double flat disk. This sows directly that repeated crops without tilling the soil of wheat-free fields in the soil-climatic conditions of Uzbekistan. In order to ensure the required quality of work of the seeder with a double flat disc, the diameter of its discs should be at least 21.4 cm. The angle of sharpening is 25°. As for the width of the bottom planting bed formed by the coulter discs, it should be at least 15 mm. The height of the meeting point of the coulter discs is at least 8.6 cm, and it was determined that the angle of deviation of the radius connecting it with the center of rotation of the disks should be 78°47′.
