Test Results of a Pneumatic Precision Seeder for Bare Cotton Seeds Under Climatic Conditions of Water-Eroded Soils

Abstract

This article presents the design and laboratory test results of a pneumatic precision seeder intended for sowing cotton seeds under soil and climatic conditions affected by water erosion. The seeding disk features suction holes with rounded triangular tips and Y-shaped barriers between them. The use of a vertical disk-type pneumatic seeder ensures the optimal grouping of seeds within the holes, enabling reliable suction of various types of agricultural crop seeds regardless of their mass and shape. It also ensures precise grouping in the feeding chamber and their accurate transfer to the furrow zone, resulting in the formation of maximally dense and accurate seed placements in the row. Such a device enhances the functionality of pneumatic seeders and enables high-precision seed placement.
