Microscopic Structures Analysis and Experimental Research of Beak

To reveal the mechanism of the easy discretization and low damage in kernel dispersal, this paper analyzes the microscopic analysis of beak structures and finds that maxillary outside cells of the beak are dense and hard. Besides, the cuticle wrapping on maxilla of chichen's beak can reduce corn kernels damage in the discrete process of corn ear. From force test of corn ear, we found that value of x direction is the maximum, second is the y direction, and the value of z direction is minimum. With reducing of water rate, the forces in three directions all decline, A 3D scanner is used to collect pointcloud data of rooster beak. Based on the point-cloud data, a roller is designed. Then the working process of discrete roller is analyzed. This research can provide a discussion for developing a corn thersher.
