EFFECT OF BLADE TYPE, CUTTING VELOCITY AND STALK CROSS SECTIONAL AREA OF CHICKPEA STALKS ON CUTTING ENERGY, CUTTING FORCE AND SPECIFIC ENERGY
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
A study was carried out to investigate the effect of blade type, cutting velocity and cross sectional area of stalks on cutting energy, cutting force and specific energy required for cutting of chickpea stalks. A pendulum type impact test rig was designed and developed to measure the cutting energy. The bundled chickpea stalks were fitted firmly in the stalk holder to replicate stalks stand in the field. Two types of blades viz., smooth edge and serrated types were used for the present study. The results showed that the cutting energy, cutting force and specific energy requirement were decreased as the cutting velocity increased for both type of blades whereas these values were increased as the cross sectional area of chickpea stalks increased. Among the two types of blades used for experiments, serrated type blade required less cutting energy, cutting force and specific energy as compared to that of smooth edge type blade at all cutting velocities and diameters of stalks.
