Ocena energetyczna sekcji roboczej obsypnika ziemniaczanego z drgajacym korpusem

W korzystnym zakresie prędkości drgający korpus obsypnika ziemniaczanego charakteryzuje się niższym zapotrzebowaniem energetycznym w stosunku do korpusu sztywnego.

The aim of laboratory research, carried out in a soil bin, was an enegetic evaluation of two different constructions of the section of potato ridger. The section with vibratory frame, held by an elastic conical element, was compared to the traditional section. Three working depths and four velocities of work movement were used. Changes in force demand for pulling and frame vibrations were recorded. The results were analysed stastically. The obtained regression equations described the changes in pulling force in relation to the speed and the working depth. The favourable range of working speed of that frame was in the range of 0.75-1.80 m/s.
