Abstract: In order to do a good job in research teaching, on the one hand, combined with the realization of the goal of "carbon neutrality" in the grain storage industry, the energy pile technology was innovatively applied to the grain silo structure for the first time,and a green grain storage system was designed. On the other hand, in view of the teaching difficulties of the green grain storage system of grain silo energy pile, 3D printing technology is used to design supporting teaching aids for popular science from three aspects of appearance application and technology popularization information feedback, and teaching aids for popular science are used to intuitively interpret the composition of the grain silo system and energy transfer mechanism, so as to give students different teaching experiences and broaden their horizons while learning basic knowledge points. Improve innovative thinking.
