RESULTS OF RESEARCH OF A COIL SEEDING MACHINE WITH A CONTINUOUS COATING OF A VALVE MADE OF RUBBER WITH SPIKES

Abstract

To create a uniform and continuous flow of seeds, to ensure stable seeding of the established norm, to reduce crushing – all these are the main tasks of the seeding machine. Seeding machines must have a reliable and convenient adjustment of the seeding rate for various crops, be universal and easy to use. The work, devoted to improving the quality indicators of grain crops by advancing the technological process of the coil seeding machine with a continuous coating of a valve made of rubber with spikes, is relevant and has an important economic and business significance for the Rus-sian agroindustrial complex. The article presents the results of laboratory studies of the coil seeding device with a continuous coating of a valve made of rubber with spikes, the results of field studies of an experimental seed drill with such seeding devices, and the dependence of the uneven distribution of seeds along the length of the row on the speed of the device unit is obtained. The use of an experimental seeder with coil seeding devices with the continuous coating of valves of rubber with spikes showed the feasibility of using a seeder with such experimental seeding devices for sowing grain seeds in the range of 7.8...9.7 km/h. The increase in the yield of spring wheat of the "Trizo" variety, when sown with the experimental seeder, counted 12 %.
