Development and Optimization of Rotary Blade for Tillage Equipment
DOI:10.30954/0974-1712.08.2018.9
Abstract:
In comparison with tractor drawn implements, rotary tillers are of particular interest in final seedbed preparation. In India vertical axis rotary tiller has been introduced in recent years by some farm equipment manufacturers. Farmers claim difference between horizontal and vertical axis rotary action but there are no scientific work compare them. Some research has been done on comparison between rotavator and conventional tillage implements. In this research, a quantitative basis for the description of torque created by different rake angle is given. The design optimization in terms of torque requirement has been carried out for the different rake angle viz., 5, 10 and 15 degree; forward speed viz., 2.0, 2.5, 3.0 and 3.5; rotor rpm viz., 220, 270 and 310. At all groups the investigations indicated that the optimum torque was produced at 2.5 kmph with 270 rpm when the rake angle is 100.
