RESULTS OF EXPERIMENTAL RESEARCHES OF THE SIZE OF GRAIN DAMAGE DURING TRANSPORTATION OF WHEAT ON THE SPIRAL CONVEYOR WITH EQUAL INCREASED VOLUTE STEP OF COIL

In the Scientific Work the results of experimental researches of the size of grain damage during transportation of wheat and barley on the spiral conveyor with equal increased volute step of coil in the direction of the freight action are described; the regression equations of the size of grain damage Тsм in depends of the increasing of the whorl step on one volute step ΔТ , angle of slope of the conveyor γ and frequency of rotation of the screw n in such borders of changes of incoming factors: 0,003 ≤ ΔТ ≤ 0,007 (m); 15 ≤ γ ≤ 45 (degrees); 100 ≤ n ≤ 400 (turns/min) are received. Due to the applied program the graphic reflection of the intermediate general regression models shown as quadratic review surfaces and their two-dimensional cuts of the grain damages
