SUBSTANTIATION OF WORK QUALITY INDICATORS OF THE EASTERN GALEGA SEEDS SCARIFICATOR

Based on the studies, a seed scarifier has been created that sequentially performs two operations – scarification and treatment with a microbiological preparation. The shape of the blades and their changing installation angle on a rotating disk allows to adjust the angle of contact of the seeds with the abrasive surface and thereby improve the quality of processing. The use of the developed device for scarification of Eastern galega seeds ensured highquality pre-sowing treatment of seeds. Compared with the existing scarifier, in the recommended range of disc speeds of 900...1100, the proposed scarifier showed a decrease in the degree of crushing of seeds by 0,2...0,4 %, an increase in the degree of scarification by 2...3 % and the degree of germination by 4...5 %.
