Description

Technical Field

[0001] This invention relates to the field of fruit storage prediction technology, specifically to a device and method for predicting the storage period of fruits. Background Technology

[0002] As urban living standards improve, people have increasingly higher requirements for agricultural products in terms of safety, freshness, and many other aspects. However, due to their inherent characteristics and the relatively dispersed production and sales areas, fruits need to be stored and transported to other regions for sale and processing after harvesting and simple processing. Before storage, it is necessary to predict the storage period of the fruits to prevent them from rotting before reaching their destination due to excessive transportation time. This prediction is usually made after checking the current condition of the fruits.

[0003] The patent application number 202420623356.X mentions "a fruit inspection machine". This device, in conjunction with an electric guide rail, can detect the size of fruit in multiple directions, reducing the deviation caused by human factors and the resulting inaccurate statistical data. It solves the problem that existing devices can only detect a single parameter of the fruit and the detection results are incomplete. However, after the above device completes the detection and predicts the storage period of the fruit, the storage period will change due to different transportation environments and storage conditions, resulting in inaccurate prediction of the storage period of the fruit. Sampling and testing are still required during transportation, which is cumbersome and time-consuming. Summary of the Invention

[0013] According to the above technical solution, the input ends of the rotating motor, gas detector, camera, inspection lamp, and electric push rod are electrically connected to the output end of the external power supply, and a horizontal stop bar is welded in the middle of the inspection hole. The camera and inspection lamp are located on both sides of the horizontal stop bar.

[0014] According to the above technical solution, a switching auxiliary component is installed inside the storage box and the bottom support box, and the switching auxiliary component includes a switching motor;

[0015] A switching motor is installed in the middle of the bottom of the storage box. An output tube is fixedly connected to the top of the output shaft of the switching motor. Air supply holes are symmetrically opened at the bottom of the output tube. The output tube passes through one end of a horizontal tube, and the bottom of the other end of the horizontal tube is connected to an air pump.

[0016] A transmission air pipe is rotatably installed through the middle of the storage box. Hollow hexagonal blocks are welded to the top of both the transmission air pipe and the output pipe. A hexagonal hole is opened at the bottom of the transmission air pipe. A base plate is fixedly sleeved on the transmission air pipe near the bottom surface of the storage box. Fixed holes are evenly opened on the bottom surface of the storage box. Movable holes are opened on the base plate corresponding to the fixed holes. A partition frame is evenly fixedly connected to the outside of the transmission air pipe. An air bladder is glued inside the partition frame. A one-way valve is installed at one end of the air bladder. One end of the one-way valve passes through the side of the transmission air pipe. The bottom end of a transparent porous tube is connected to the outside of the base plate. A top cover is placed on the top of the storage box.

[0017] The top of the transmission air pipe is rotatably fitted with an inner end cap, and the bottom of the inner end cap has a slot corresponding to the top of the partition frame. A buffer air pad is evenly adhered to the bottom of the inner end cap.

[0018] According to the above technical solution, the input ends of the switching motor and the air pump are electrically connected to the output end of the external power supply, the bottom ends of the switching motor and the air pump are flush and both are connected to the bottom support box by screws, and the top ends of the output pipe and the transmission air pipe are inlaid with sealing gaskets.

[0019] According to the above technical solution, the fixed hole and the movable hole are the same in shape and size, and the contact surface between the bottom support box and the chassis is a smooth plane.

[0020] According to the above technical solution, a method for using a fruit storage period prediction device includes the following steps;

[0021] S1: Test preparation: Place a bagged mixture of silica gel desiccant and iron powder into the annular drying cage, place the base into the bottom support box, at this time the fixing hole and the movable hole coincide, and gently place the fruits to be stored on the top surface of the base in sequence.

[0022] S2: Place and stack the tubes, connect the test tube clamps to the test hole, align the bottom support ring at the bottom of the storage box with the top of the bottom support box, connect the hexagonal hole at the bottom of the transmission tube with the hollow hexagonal block at the top of the output tube, and install a gas detector at one end of the test tube.

[0023] S3: Detection and prediction. Periodically turn on the inspection light and camera to detect changes in the fruit through optical observation. Switch the motor to drive the transmission air tube to rotate, which in turn drives the fruit on the top of the chassis to rotate, so as to conduct a comprehensive observation and inspection of the fruit. The blow-suction pump draws air from the storage box to the gas detector for testing.

[0024] S4: With the change of environment, the rotating motor drives the blow-suction pump to rotate 180° in the ventilation pipe. The blow-suction pump blows air into the bottom support box. After the air is dried and deoxygenated, the original air in the storage box is discharged, and the environment for storing fruit becomes low-oxygen and dry.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. Equipped with an adjustment and prediction component, during storage, the inspection light and camera are periodically turned on to detect changes in the fruit through optical observation. The rotating motor drives the blow-suction pump to rotate inside the ventilation pipe. The semi-circular baffle covers the end of the semi-circular pipe, and at this time, the first switching hole and the second switching hole coincide. The semi-circular pipe and the bottom support box are connected. The blow-suction pump draws air from the storage box to the gas detector for testing. The content of ethylene, oxygen, and ethanol produced by fruit decay is detected to assess the current state of the fruit. Then, the storage time is predicted again based on 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 prediction.

[0027] If the humidity and oxygen content inside the storage box are too high, leading to a reduction in storage time, each storage box and the bottom support box are connected. The rotating motor drives the blower-suction pump inside the gear ring to rotate 180° inside the ventilation pipe. The ventilation pipe is not connected to the inside of the bottom support box. The blower-suction pump blows air into the bottom support box and activates the electric actuator, so that the windproof ring no longer blocks the side air vents. The air is dried by the silica gel desiccant in the annular drying cage and deoxygenated by the iron powder. The original air in the storage box is discharged, making the environment for storing fruit low in oxygen and dry, thereby extending the predicted storage time of the fruit.

[0028] 2. It is equipped with a switching auxiliary component. If it is necessary to move the fruit storage position frequently, the air pump can be activated. The inflating air bladder will compress the stored fruit, causing the fruit to squeeze against each other. This prevents the fruit from colliding and being damaged when moving the stacked storage boxes. In addition, the inflating air bladder is made of flexible material, so it will not damage the fruit due to excessive pressure, which is beneficial to the storage of the fruit.

[0029] The switching motor is activated, which drives the transmission air pipe to rotate, thereby causing the fruit on the top surface of the chassis to rotate as well. This allows the camera to observe and inspect the fruit more comprehensively, improving the accuracy of the inspection.

[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 hole and the movable hole no longer overlap, so the storage boxes will not interfere with each other, which is beneficial to the storage of fruit.

[0031] In summary, the adjustment prediction component can periodically detect the current condition of the fruit and extend the storage prediction time by changing the environment inside the storage box according to storage needs. The switching 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. It also better assists the adjustment prediction component. The two components work together to achieve better detection and prediction accuracy. Attached Figure Description

[0057] like Figure 11 As shown, a method of using a fruit storage period prediction device includes the following steps;

[0058] S1: Test preparation: Place a bagged mixture of silica gel desiccant and iron powder into the annular drying cage 211. Place the base 309 into the bottom support box 202. At this time, the fixing hole 310 and the movable hole 311 coincide. Gently place the fruits to be stored on the top surface of the base 309 in sequence.

[0059] S2: Place and stack the test tube 222 into the test hole 223, align the bottom support ring 201 at the bottom of the storage box 1 with the top of the bottom support box 202 and stack them, connect the hexagonal hole 308 at the bottom of the transmission air pipe 306 and the hollow hexagonal block 307 at the top of the output pipe 302, and install the gas detector 217 at one end of the gas test tube 216.

[0060] S3: Detection and prediction. Periodically turn on the inspection light 221 and camera 220 to detect changes in the fruit through optical observation. Switch the motor 301 to drive the transmission air pipe 306 to rotate, which in turn drives the fruit on the top surface of the chassis 309 to rotate as well, so as to conduct a comprehensive observation and inspection of the fruit. The blow-suction pump 208 draws air from the storage box 1 to the gas detector 217 for testing.

[0061] S4: When the environment changes, the rotating motor 214 drives the blow-suction pump 208 to rotate 180° in the ventilation pipe 204. The blow-suction pump 208 blows air into the bottom support box 202. After the air is dried and deoxygenated, the original air in the storage box 1 is discharged, and the environment for storing fruits becomes low-oxygen and dry.

[0062] The working principle and usage process of this invention are as follows: Place the bottom support box 202 in the designated position, put a bagged mixture of silica gel desiccant and iron powder into the annular drying cage 211 to ensure that the gap in the annular drying cage 211 is large enough to facilitate the passage of air, and place the base plate 309 into the bottom support box 202. At this time, the fixing hole 310 and the movable hole 311 coincide. Gently place the fruits to be stored on the top surface of the base plate 309 in sequence. When placing them, check that the fruit skin is intact and undamaged. The inner end cap 317 is sleeved on the top of the transmission air pipe 306, and the slot 318 is engaged with the top of the partition frame 312.

[0063] The inspection tube 222 is snapped into the inspection hole 223. Then, the bottom support ring 201 at the bottom of the storage box 1 is aligned with the top of the bottom support box 202 and stacked. The splicing tube 219 is embedded into the top of the bottom support tube 205. The hexagonal hole 308 at the bottom of the transmission air tube 306 and the hollow hexagonal block 307 at the top of the output tube 302 are connected. Multiple storage boxes 1 are stacked in sequence. Finally, the top of the splicing box 218 at the top is closed, and the top cover 316 is placed on the top storage box 1. A gas detector 217 is installed at one end of the gas inspection tube 216, and all electrical equipment is connected to the control platform for subsequent operation.

[0064] If the fruit storage location needs to be moved frequently during storage, the air pump 305 can be started. Air enters the air bladder 313 through the horizontal pipe 304, air inlet 303, output pipe 302, transmission air pipe 306 and one-way valve 314 in sequence. The inflated air bladder 313 will squeeze the stored fruit, causing the fruit to squeeze against each other, preventing collision damage caused by the fruit colliding with each other when moving the stacked storage boxes 1. In addition, the inflated air bladder 313 is made of flexible material, which will not damage the fruit due to excessive pressure, which is beneficial to the storage of fruit.

[0065] During storage, the inspection light 221 and camera 220 are periodically turned on to detect changes in the fruit through optical observation. The rotating motor 214 is then activated, driving the blow-suction pump 208 within the gear ring 212 via gear 213. This causes one end of the semi-circular tube 209 to align with one side of the semi-circular baffle 207, blocking the end of the semi-circular tube 209. At this time, the first switching hole 206 and the second switching hole 210 coincide, aligning the semi-circular tube 209 and the bottom support box 20. 2. The internal structure is interconnected, and each storage box 1 is connected to the splicing box 218 via a gas testing tube 216. A blow-suction pump 208 draws air from the storage box 1 to a gas detector 217 for testing. The detector detects the content of ethylene, oxygen, and ethanol produced by the fruit during decay, assesses the current state of the fruit, and then predicts the storage time again based on changes in appearance and storage environment. The initial storage time prediction is then adjusted. The operation is simple, thereby improving the accuracy and efficiency of the prediction.

[0066] During the above detection process, the switching motor 301 can be activated, which drives the transmission air pipe 306 to rotate, thereby causing the fruit on the top surface of the chassis 309 to rotate as well, so that the camera 220 can observe and detect the fruit more comprehensively and improve the accuracy of the detection.

[0067] After detection and prediction, if the humidity and oxygen content in storage box 1 are high, resulting in a reduced storage time, and if it is necessary to extend the storage time, all storage boxes 1 and the bottom support box 202 are connected, and the rotating motor 214 is started. The rotating motor 214 drives the blow-suction pump 208 in the gear ring 212 to rotate 180° in the ventilation pipe 204 through the gear 213, so that one end of the semi-circular tube 209 and one side of the semi-circular baffle 207 no longer overlap, so that the semi-circular baffle 207 no longer blocks the end of the semi-circular tube 209. At this time, the first switching hole 206 and the second switching hole 210 also no longer overlap, and the ventilation pipe 204 is not... The bottom support box 202 is connected to the inside. The blower pump 208 blows air into the bottom support box 202 and starts the electric push rod 230 to push the transmission tube 228 upward, so that the windproof ring 225 no longer blocks the side air 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, becoming a dry gas with low oxygen content. It enters the storage box 1 from the bottom and discharges the original air in the storage box 1, making the environment for storing fruit low oxygen and dry, thereby extending the storage time of the fruit and preventing the fruit from rotting prematurely.

[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 to rotate, 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 beneficial to the storage of fruit.

[0069] The adjustment prediction component 2 can periodically detect the current condition of the fruit and change the environment inside 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 assists the adjustment prediction component 2. The two components work together to achieve better detection and prediction accuracy.
