This invention discloses a dual-cold-source intelligent switching system for sweet potato storage, relating to the field of storage technology. It includes an intermediate chamber with storage compartments on both sides. A spraying assembly is installed on the lower side of each storage compartment, with a mounting plate on the spraying assembly. Sweet potatoes are placed on the upper side of the mounting plate. An air intake wheel is installed between the intermediate chamber and the storage compartments. An air intake assembly is installed on each storage compartment. A front fan and a rear fan are installed on both sides of the intermediate chamber. A refrigerator is installed on one side of both the intermediate chamber and the storage compartments. This technical solution utilizes both natural temperature for cooling and a refrigerator for cooling, resulting in significant energy savings. The spraying assembly in the storage compartment automatically sprays pesticides, ensuring a safe storage environment and greatly improving the quality of sweet potato storage.

The sweet potato storage frame comprises a cuboid frame, the top face of the cuboid frame is open, and the four side faces and the bottom face of the cuboid frame are hollowed out. Supporting legs are arranged at the lower part of the frame; a first positioning unit is arranged at the bottom of one group of opposite side surfaces, and a second positioning unit coupled with the first positioning unit of the other sweet potato storage frame is arranged at the top. The problems that ventilation is not smooth and humidity is not easy to adjust in a traditional sweet potato storage mode are effectively solved, and the risk that sweet potatoes are rotted due to anaerobic respiration in the storage process is remarkably reduced. And the first positioning unit is matched with the second positioning unit at the top, so that accurate positioning and stable connection of the storage frames during stacking are realized, and the reliability of multi-layer stacking is greatly improved. And through cooperative work of the storage frame, the lifter, the forklift and other equipment, accurate butt joint and stable operation in the carrying and stacking process are facilitated, and the working efficiency and safety are remarkably improved.

The utility model relates to the field of storage equipment, in particular to a device for prolonging normal-temperature storage time of sweet potatoes. A plurality of groups of sweet potato storage baskets are detachably mounted between the two groups of supporting frames, the top surfaces of the sweet potato storage baskets are open, the side surfaces and the bottom surfaces are provided with air holes, and mounting plates extending outwards are arranged on the side parts of the tops of the sweet potato storage baskets. According to the device for prolonging the normal-temperature storage time of the sweet potatoes, through cooperation of the supporting frames, the sweet potato storage baskets, the air holes, the mounting plates and the like, the sweet potato storage baskets are mounted between the two sets of supporting frames, then the sweet potatoes are placed in the sweet potato storage baskets, and then the upper layer of sweet potato storage baskets are mounted and placed upwards in sequence. The sweet potatoes are separated by the multiple sweet potato storage baskets, serious extrusion damage caused by stacking of all the sweet potatoes is avoided, paper scraps can be placed at the bottoms of the sweet potato storage baskets, and the paper scraps are used for absorbing redundant moisture of the sweet potatoes and play a role in buffering at the same time. Meanwhile, the vent holes can ventilate, so that the sweet potatoes are prevented from spoilage.
