CONSTRUCTION OF THE FLUTED (-FORCE) FEED OF THE SEEDER FOR SEEDING GRAIN CROPS
Seed-sowing devices used in modern grain seeders with a mechanical drive do not fully meet the agrotechnical requirements for the quality of sowing. On the basis of the analysis of modern constructions of seed-sowing devices on grain seeders, nowadays, sowing devices of fluted-roll feed type with straight grooves are mainly used. During operation of seed-sowing devices of this design, the sowing of seeds in the seed tubes and further into the seed spouts and then into the supply colter of the seeders is carried out by a pulsating flow. It is partially leveling when moving in the seed spouts, however, when sowing, there is uneven distribution of seeds throughout the feeding area, longitudinal stability of seeds sowing of cereal crops, stability of total sowing and traumatizing of seeds of cultivated crops. This does not meet the agrotechnical requirements, leads to a decrease in the yield of grain crops and an increase in the cost of their production. Studies dedicated to improving the quality of sowing the cereal crops at the expense of perfecting the technological process of operation of the fluted-roll feeding device are relevant and have important economic and management significance for the AIC of Russia. The article presents the design and principle of operation of the developed fluted-roll feeding device, which ensures the longitudinal stability of seeds sowing of cereal crops, the stability of general sowing and the reduction of traumatizing to the seeds of cultivated crops.
