[0020] According to the above technical solution, a method for using a device for predicting the storage period of fruits comprises the following steps:

[0024] S4: The environment changes. The rotating motor drives the blowing and suction dual-purpose pump to rotate 180° in the ventilation pipe. The blowing and suction dual-purpose pump blows air into the bottom support box. The air is dried and deoxygenated, and the original air in the storage box is discharged. The environment for storing fruits becomes low-oxygen and dry.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. An adjustment prediction component is provided. During the storage process, the inspection light and the camera are turned on regularly to detect the changes of the fruit through optical observation. The rotating motor drives the blowing and suction dual-purpose pump to rotate in the ventilation tube. The semicircular baffle covers the end of the semicircular tube, and at this time, the first switching hole and the second switching hole coincide. The semicircular tube and the bottom support box are connected internally. The blowing and suction dual-purpose pump extracts the air in the storage box to the gas detector for detection, and detects the content of ethylene and oxygen emitted by the fruit, and ethanol produced by the decay of the fruit, etc., to evaluate the current state of the fruit, and then the storage time is predicted again through the changes in appearance and storage environment, and the initial storage time prediction is adjusted. The operation is simple, thereby improving the accuracy and efficiency of the prediction;

[0027] If the humidity and oxygen content in the storage box are high and the storage time is reduced, each storage box is connected to the bottom support box, and the rotating motor drives the blowing and suction dual-purpose pump in the gear ring to rotate 180° in the ventilation pipe through the gear. The ventilation pipe is not connected to the inside of the bottom support box. The blowing and suction dual-purpose pump blows air into the bottom support box and starts the electric push rod so that the wind shield ring no longer blocks the side wind holes. The air is dried by the silica gel desiccant in the annular drying cage and deoxygenated by the iron powder, and the original air in the storage box is discharged, so that the environment for storing fruits becomes low-oxygen and dry, thereby extending the predicted storage time of the fruits.

[0028] 2. A switching auxiliary component is provided. If the fruit storage position needs to be moved frequently, the air pump can be started. The expanded air bag will squeeze the stored fruits, so that the fruits are squeezed against each other, to prevent collision damage caused by collision between fruits when moving the stacked storage boxes. The expanded air bag is made of flexible material and will not damage the fruits due to excessive pressure, which is conducive to the storage of fruits.

[0029] Start the switching motor, which drives the transmission air pipe to rotate, and then drives the fruit on the top of the chassis to rotate, so that the camera can observe and detect the fruit more comprehensively, improving the accuracy of detection;

[0030] After the detection and prediction operations are completed, the switching motor is started, the switching motor drives the transmission air pipe to rotate, the chassis rotates, and the fixed holes and the movable holes no longer overlap, the storage boxes will not interfere with each other, which is conducive to the storage of fruits.

[0031] In summary, the adjustment prediction component can regularly detect the current condition of the fruit, and change the environment inside the storage box according to storage needs to extend the storage prediction time. Switching the auxiliary component facilitates better storage of the fruit, reduces collisions between fruits, and assists the optical detection of the camera, making the detection results more comprehensive and accurate, and better assisting the adjustment prediction component. The two components work together to achieve better detection and prediction accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the expanded air bag 313 is made of flexible material, and the fruits will not be damaged due to excessive pressure, which is conducive to the storage of fruits.

[0065] During the storage process, the inspection light 221 and the camera 220 are turned on regularly to detect the changes of the fruit through optical observation, and the rotating motor 214 is started. The rotating motor 214 drives the blowing and suction dual-purpose pump 208 in the gear ring 212 to rotate in the ventilation tube 204 through the gear 213, so that one end of the semicircular tube 209 coincides with one side of the semicircular baffle 207, so that the semicircular baffle 207 covers the end of the semicircular tube 209, and at this time the first switching hole 206 and the second switching hole 210 coincide, and the semicircular tube 209 and the bottom support box 20 2 are internally connected, and at the same time, because each storage box 1 is connected to the spliced ​​splicing box 218 through the gas testing tube 216, the blowing and suction dual-purpose pump 208 extracts the air in the storage box 1 to the gas testing instrument 217 for testing, and detects the content of ethylene and oxygen emitted by the fruit, and ethanol produced by the fruit rotting, so as to evaluate the current state of the fruit, and then predict the storage time again through the changes in appearance and storage environment, and adjust the initial storage time prediction, which is simple to operate, thereby improving the accuracy and efficiency of the prediction;

[0066] During the above detection process, the switching motor 301 can be started, and the switching motor 301 drives the transmission air pipe 306 to rotate, thereby driving the fruit on the top surface of the chassis 309 to rotate, so that the camera 220 can observe and detect the fruit more comprehensively, thereby improving the accuracy of the detection;

[0067] After the detection and prediction are completed, if the humidity and oxygen content in the storage box 1 are high and the storage time is reduced, if the storage time needs to be extended, each storage box 1 is connected to the bottom support box 202, and the rotating motor 214 is started. The rotating motor 214 drives the blowing and suction dual-purpose pump 208 in the gear ring 212 to rotate 180° in the ventilation tube 204 through the gear 213, so that one end of the semicircular tube 209 and one side of the semicircular baffle 207 no longer overlap, so that the semicircular baffle 207 no longer blocks the end of the semicircular tube 209. At this time, the first switching hole 206 and the second switching hole 210 no longer overlap, and the ventilation tube 204 does not The bottom support box 202 is connected to the inside of the bottom support box 202, and the blowing and suction dual-purpose pump 208 blows air into the bottom support box 202, and the electric push rod 230 is started to push the transmission tube 228 upward, so that the wind shield ring 225 no longer blocks the side wind hole 224 to prevent the air pressure in the storage box 1 from being too high. The air is dried by the silica gel desiccant in the annular drying cage 211 and deoxygenated by the iron powder, and becomes dry gas with low oxygen content, and enters the storage box 1 from the bottom in turn, and the original air in the storage box 1 is discharged, so that the environment for storing fruits becomes low-oxygen and dry, thereby extending the storage prediction time of fruits to prevent fruits from rotting in advance;

[0068] After the detection and prediction operations are completed, the switching motor 301 is started, the switching motor 301 drives the transmission air pipe 306 to rotate, the chassis 309 rotates, and the fixed hole 310 and the movable hole 311 no longer overlap, the storage boxes 1 will not interfere with each other, which is conducive to the storage of fruits;

[0069] The adjustment prediction component 2 can regularly detect the current condition of the fruit, and change the environment in the storage box 1 according to the storage needs to extend the storage prediction time. The switching auxiliary component 3 facilitates better storage of the fruit, reduces collisions between fruits, and assists the optical detection of the camera 220, making the detection results more comprehensive and accurate, and better assisting the adjustment prediction component 2. The two components cooperate with each other to achieve better detection and prediction accuracy.
