Design and Experimental Study of a Bionic Blade for Harvesting the Wild Chrysanthemum Stem

Wild chrysanthemum has a high medicinal value. Its mechanized harvest can improve harvesting efficiency, reduce labor costs and planting benefits, which is an important way to promote artificial planting. However, one of the difficulties in large diameter hardness stem, leading cutting resistance power consumption. In order consumption, bionic blade designed this paper by employing bionics principle contour cricket’s upper jaw incisor lobe instead sharp triangular teeth standard harvester blade. Using finite element method, cutting-edge angle, reciprocating speed were taken as test factors. The maximum shear force consumption evaluation indexes. At same time, center combination simulation was carried out optimize body determine optimal speed. When angle 21°, 66°, 1.29 m/s, minimal. results showed that cutter reduced 18% 15.8%. bench 10.5% 10.8%, respectively, when entire wild stem cut. provide reference for mechanical stems.
