Virus preventing and controlling device for potato storage

The invention belongs to the technical field of agricultural product storage equipment, and particularly relates to a virus preventing and controlling device for potato storage. The virus preventing and controlling device for potato storage comprises a storage box body, a sealing strip mouth, a sealing cover, two temperature control mechanisms, a gas changing mechanism and a gas control mechanism;the sealing strip mouth is arranged at the top of the storage box body; the sealing cover is arranged on the sealing strip mouth; the two temperature control mechanisms are arranged on the front sideand the right side of the storage box body respectively; the gas changing mechanism is arranged on the lower part of the left side of the storage box body; the gas control mechanism is arranged on the right side of the storage box body; the temperature control mechanism maintains the internal part of the storage box body to be at constant temperature, so that potatoes can be stored at constant temperature and are not liable to occur lesion; the gas changing mechanism can change gas in the storage box body, so that germs are not brought when the gas in the storage box body is changed; the gascontrol mechanism can vacuumize the storage box body and fill carbon dioxide gas, so that the potatoes can be storage under the pure gas environment, aerobic respiration is reduced, lesion is effectively prevented and the storage time is prolonged.
