RESEARCH THE SEED DAMAGE BY COMBINES WITH VARIOUS TECHNOLOGICAL SCHEMES OF THRASHING
Abstract
The results of the study found: in the axial-flow type threshing unit the increase rotor speed from 520 rpm to 810 rpm leads to a corresponding increase microdamages seed from 25-30 % to 45-50 %; in the drum type threshing machine the increase in frequency of rotation of the drum with a 700-760 rpm to 820 to results in a corresponding increase in microdamages seeds from 37-38 % to 41-44 %. In order to reduce the level of damage to the seed it is appropriate to provide for the development of domestic seed-breeding combine.
