[0039] Compared with the prior art, the sweet potato storage device can automatically arrange multiple holding components 3 containing sweet potatoes horizontally in the cellar 5 through the setting of the conveying mechanism 4, thereby increasing the storage space and storage capacity in the cellar 5.

[0040] The working process of the sweet potato storage device of the utility model is as follows: when performing the placing operation, the filled holding component 3 is placed on the shield 21, and the support block 212 is engaged with the groove, and the control start button in the control key is pressed to start the propulsion motor 24, and the propulsion motor 24 drives the propulsion screw 23 to rotate through the transmission component 25, and then pushes the shield 21 to move toward the lifting rail 11 through the push block 22 until the protrusion 31 is pushed into the recess. In the process of the protrusion 31 pushing into the recess, the metal plug 181 is pushed to move into the contraction groove and squeeze the contraction spring 182. After the protrusion 31 is inserted into place, the metal plug 181 is pushed into the slot 311 by the contraction spring 182 and is engaged and fixed with the protrusion 31, and at this time, the electromagnetic component 183 is in a power-off state. After the shutter 21 moves into position, the controller controls the winding motor 15 to start, the winding motor 15 drives the winding gear 172 to rotate through the driving gear 171, and the winding gear 172 drives the winding roller 14 to rotate through the winding shaft 173. The winding roller 14 controls the retraction and release of the pulling rope 13. The pulling rope 13 is retracted first, and the holding component 3 is driven to rise through the lifting block 12. The controller controls the propulsion motor 24 to drive the shutter 21 to be retracted along the positive direction of the X-axis. After the retraction, the pulling rope 13 is relaxed, and the lifting block 12 and the lifting block 12 are fixed thereto. The containing component 3 moves downward under its own weight until the containing component 3 abuts against the conveyor belt 41. At this time, the groove is engaged with the limit block 412. After moving into place, the controller energizes the electromagnetic component 183, and the electromagnetic component 183 is magnetic. The metal plug 181 moves into the contraction groove and separates from the protrusion 31 under the attraction of the electromagnetic component 183. The controller starts the conveying mechanism 4, and the conveying motor rotates forward through the conveyor belt 41 to drive the containing component 3 to move inward. After moving into place, the next containing component 3 is placed.

[0041] When taking out, the conveyor belt 41 is driven by the reverse rotation of the conveying motor to push the containing assembly 3 on it to engage with the metal plug 181 on the lifting block 12, and the electromagnetic component 183 is in a power-off state. The winding motor 15 is started, and the lifting block 12 and the containing assembly 3 are driven to rise to the top of the lifting rail 11 through the pulling rope 13, and the propulsion motor 24 controls the shield 21 to be pushed out and against the lifting rail 11, and the winding motor 15 controls the lifting block 12 and the containing assembly 3 to move downward through the pulling rope 13 so that the containing assembly 3 is engaged with the support block 212. The electromagnetic component 183 is energized to separate the metal plug 181 from the protrusion 31, and the propulsion motor 24 pulls the containing component 3 away from the entrance of the cellar 5 through the baffle 21. The worker can remove the containing component 3 on one side of the entrance of the cellar 5 and take out the sweet potatoes in the containing component 3 for use. The sweet potatoes on the lower side can be taken out through the drawer 33. The drawer 33 can ensure that the sweet potatoes are easy to take out and avoid damage caused by squeezing the sweet potatoes together, thereby achieving a better preservation effect.

The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
