Impact of working parameters on loading of stone rake rotor
Journal Title: Annals of Warsaw University of Life Sciences- SGGW - Agriculture - Year 2015, Vol 66, Issue 66
Abstract
The objective of this study was to determine the impact of the kinematic coefficient and the angle of positioning of the stone rake rotor upon its torque. Research was conducted in a soil bin. In order to achieve the objective, a stone rake model was developed and fixed to the frame of the soil bin tool trolley, using supports. The external diameter of the rotor was 400 mm. The study was performed at the rotational speed of 80 rpm, at two speeds of movement of the picking unit and five angles of positioning of the rotor in relation to perpendicular direction to tool movement within the range of 15 to 35°. The impact of the technical parameters examined on torque driving the stone rake rotor was found to be statistically significant. It was determined that the angle of positioning of the rotor shaft equal to 35° was beneficial due to the energy loads generated by the rotating unit. However, taking into account the working width of the stone rake, for practical purposes, the rotor positioning angle can be recommended to range between 25 and 30°.
