TO THE QUESTION OF DECREASE IN LOSSES OF GRAIN AT TWO-PHASE HARVESTING

Article is devoted studying of primary interaction of the deformed pick-up fingers with a roll. At selection of a roll, fingers of the pick-up can be deformed. Restoring the form, to carry out shock influence on a roll, beating out grains. The zone of the movement of fingers of the pick-up at restoration of a form is defined. It is established that with increase of an indicator of a kinematic operating mode of the pick-up λ it increases. The most active influence of fingers on a roll is observed at 1 ≤λ ≤ 3.
