Abstract:A new type of granary for corn ear was developed for farmers in order to meet the needs of rapid increase of good storage mode. The modular assembly structure was adopted, which constituted a cuboid space to store the corn ear. It was welded with pieces of steel mesh sheet, which was easier to transport and install. The test of granary loaded with corn ear proved that it had stable mechanical property, the function of mildew proof, ratproof, and natural air drying was remarkable, which can successfully reduce the loss of the grain for farmers and ensure the grain quality very well. It provided technical support for the farmers to store grain safely.
