Abstract
Abstract After determining the physical-mechanical properties of industrial grain of the corn, we decided to compare the results of experiment with properties of seed-corn. According to some agronomic researchers’ observation, there is special determination method to harvest corn-crop for producing seed-corn. Therefore, because of the observations and analysis, it is an actual theme to do research on creating new innovative corn-seed preparing technologies and grader machines based on smart technological methods. Otherwise, it is difficult to grade precise properties of corn-seed. Therefore, we created new innovative corn-seed grader machine, developed constructive scheme and its 3D model of the smart corn-seed grader machine, and based its positions. It has been known that, the width of the receiving section of the machine should be Bb =0.157 m and Bb =0.314 m when the amount of pod-corn transferred to the device in a unit time is between 1 kg/s and 2 kg/s depending on their average length, diameter and mass.
