So far the corn harvester made locally applied on the mature corn.For the foragers can not harvest corn during the harvest season,a few manufactures offer the combines with the price above the average.Moreover the kernels will easy to break when harvesting.In order to solve the above problems,the paper researched on novel bionic snapping mechanism based on the bionics principle.Compared with traditional corn snapping mechanism,the novel bionic snapping mechanism has great difference both in construction and working principle.The traditional way adopt the method of tensile and extrusion to snap corn ear.The new device designs inspiration is from artificially picking up corn ear which adopted bending and breaking.
