Modular grain dry storage system

The invention discloses a modular grain dry storage system. The modular grain dry storage system comprises grain storage boxes, a drying bin and a grain storage bin. A drying frame, a burning furnace,a first transporting mechanism and a first controller are arranged in the drying bin. The multiple grain storage boxes are arranged on the drying frame in a matrix manner, the burning furnace is usedfor drying grain in the grain storage boxes, and the first controller controls the first transporting mechanism to carry the grain storage boxes up and down, left and right and front and back. Rollershutter doors are formed in the periphery of the grain storage bin, an environment detection module is arranged on the top of the grain storage bin, a storage frame, a second transporting mechanism and a second controller are arranged in the grain storage bin, the second controller controls the roller shutter doors to be opened and closed according to environmental data detected by the environment detection module, the mul
