Description

Technical Field

[0001] The present invention relates to the technical field of potato characteristic determination technology, and specifically relates to a device for determining the storage tolerance characteristics of potatoes. Background Art

[0002] As one of the important food crops globally, potatoes play a crucial role in ensuring food security and promoting the development of the agricultural economy. During its storage process, due to factors such as respiration, water loss, and disease invasion, problems such as quality decline, sprouting, and rotting are likely to occur, resulting in significant economic losses. According to relevant data statistics, under conventional storage conditions, the loss rate of potatoes within 6 months after harvest can reach 15%-30%, severely restricting the sustainable development of the potato industry. Therefore, accurately determining the storage tolerance characteristics of potatoes is of great significance for optimizing storage strategies, extending the storage period, and reducing post-harvest losses.

[0003] In current laboratory research and practical production applications, for the determination of the storage tolerance characteristics of potatoes, the means mainly rely on manual regular observation of the appearance changes of potatoes placed in storage equipment, such as whether there are phenomena such as sprouting, epidermal shrinkage, and rotting spots, and combined with simple weight measurement to estimate the water loss situation.

[0004] However, when most traditional equipment stores potatoes, the potatoes are stacked, causing multiple potatoes to come into contact. Such a practice will lead to large-scale cross-infection, resulting in inaccurate experimental results. Summary of the Invention

[0014] Preferably, when the first storage box and the second storage box are fully opened, the weighing mechanism extends out of the second connecting box body, and when the first storage box and the second storage box are fully closed, the weighing mechanism is located inside the second connecting box body.

[0015] Preferably, a measurement method for a potato storage tolerance measurement device, which is used for the potato storage tolerance measurement device described in any one of claims 1-9, includes the following steps: First, start the motor to drive the first through-shaft to rotate, and then drive the linkage gear and the first connecting rod to rotate synchronously, so that the linkage gear and the first connecting rod on the other side also rotate synchronously. Then, the first connecting rods on both sides rotate around the first through-shaft as the central axis. The force generated by the rotation of the first connecting rod pushes the first storage boxes on both sides to move towards each other and then move to both sides. While the first connecting rod drives the first storage box to move, the first storage box drives the second connecting rod to rotate around the part where the second connecting rod is connected to the bottom case as the central axis, and then drives the second storage box and the first storage box to move towards each other and then move to both sides. Open the second storage box by pulling the handle on the first lid, place the potatoes to be stored for the experiment inside the first storage box and the second storage box, pull the handle to cover the second storage box, and then start the motor to drive the linkage gear to rotate in the reverse direction to reset the first storage box and the second storage box;

[0016] When the motor drives the first through-shaft to drive the linkage gear to rotate to control the opening and closing of the first storage box and the second storage box, it will also synchronously drive the first acceleration gear to rotate, and then drive the second acceleration gear meshing with the first acceleration gear to rotate, thereby driving the connecting shaft and the first bevel gear to rotate. Through the meshing of the first bevel gear and the second bevel gear, the second through-shaft is driven to rotate, and then the first helical gear is driven to rotate through the second through-shaft, so that the first helical gear drives the second helical gear to rotate, and then drives the threaded column to rotate. The rotation of the threaded column drives the moving plate to move on the inner wall of the second connecting box. When the first storage box and the second storage box are fully opened and closed, the weighing mechanism extends out of the inner wall of the second connecting box. When the first storage box and the second storage box are fully closed, the weighing mechanism is inside the second connecting box. Take out the potatoes stored in the first storage box and the second storage box for a period of time and place them above the weighing mechanism for weighing. Evaluate the storage characteristics of the potatoes according to the weight before storage and the measured mass.

[0017] The present invention provides a potato storage tolerance measurement device. It has the following beneficial effects:

[0018] 1. By starting the motor, driving the first through-shaft to rotate, the linkage gear and the first connecting rod rotate synchronously, pushing the first storage boxes on both sides to move to both sides, and driving the second storage boxes to move towards each other. After putting the potatoes in, pull the handle to cover the second storage box, and the reverse rotation of the motor resets the storage boxes, achieving the effect of avoiding large-scale cross-infection and quality decline, and ensuring the accuracy and reliability of the experimental results.

[0019] 2. The present invention drives the second acceleration gear through the first acceleration gear, causing the connecting shaft, the first bevel gear, and the second through shaft to rotate, and then driving the first helical gear and the second helical gear, enabling the threaded column to rotate, driving the moving plate to move on the inner wall of the second connecting box, and storing the weighing mechanism inside the second connecting box when not in use. This can avoid interference and damage to the weighing mechanism from external factors and effectively utilize the internal space of the device, making the structure of the device more compact and reasonable.

[0020] 3. The present invention drives relevant components to operate through the motor. On the one hand, it ensures the quality of experimental samples. On the other hand, it protects the key components of the device and optimizes the device structure, contributing to improving the stability, reliability, and practicality of the entire device, enhancing the value and competitiveness of the device in actual applications.

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0031] Please refer to the attached Figure 1 - attached Figure 5 , the embodiment of the present invention provides a device for measuring the storage tolerance characteristics of potatoes, including a bottom shell 1. A connecting bracket 2 is fixedly connected to the outer wall of the bottom shell 1. A motor 3 is fixedly connected to the outer wall of the connecting bracket 2. A first through shaft 4 is fixedly connected to the output end of the motor 3. The outer wall of the first through shaft 4 is rotatably connected to the inner wall of the bottom shell 1. A linkage gear 5 is fixedly connected to the outer wall of the first through shaft 4. A first connecting rod 6 is fixedly connected to the outer wall of the linkage gear 5. A first storage box 7 is fixedly connected to the outer wall of the first connecting rod 6. A second connecting rod 8 is rotatably connected to the outer wall of the bottom shell 1. The outer wall of the second connecting rod 8 is rotatably connected to the inner wall of the first storage box 7. A second storage box 9 is rotatably connected to the outer wall of the second connecting rod 8. A first box cover 10 is arranged on the upper surface of the second storage box 9.

[0032] Specifically, first, start the motor 3 to drive the first through shaft 4 to rotate. Use the motor 3 as the driving source to drive the rotation of the remaining components. And the motor 3 has self-locking, which is prior art and will not be elaborated here. Then drive the linkage gear 5 and the first connecting rod 6 to rotate synchronously. Through the meshing of the two linkage gears 5 on both sides, the linkage gear 5 and the first connecting rod 6 on the other side also rotate synchronously. Then, with the first through shaft 4 as the central axis, the two first connecting rods 6 rotate to push the two first storage boxes 7 to move towards each other and move to both sides. The thrust of the first connecting rod 6 drives the first storage box 7 and the second storage box 9 to move synchronously, so that the first storage box 7 and the second storage box 9 are opened. When the first connecting rod 6 drives the first storage box 7 to move, the first storage box 7 drives the second connecting rod 8 to rotate with the part where the second connecting rod 8 is connected to the bottom shell 1 as the central axis. The force of the movement of the first storage box 7 drives the second connecting rod 8 to move, so that the second connecting rod 8 rotates, and then drives the second storage box 9 and the first storage box 7 to move towards each other and move to both sides. Then, by starting the motor 3 to drive the linkage gear 5 to rotate in the reverse direction, the first storage box 7 and the second storage box 9 are reset. When a certain potato sample gets diseased or rots, it is not easy to quickly spread to other potatoes, thus avoiding large-scale cross-infection and quality decline, and ensuring the accuracy and reliability of the experimental results.

[0033] Please refer to the attached Figure 1 , attached Figure 2 and attached Figure 3 , the lower surface of the first storage box 7 is attached to the upper surface of the bottom shell 1, and the lower surface of the second storage box 9 is attached to the upper surface of the first storage box 7.

[0034] Specifically, the bottom case 1 provides a supporting force for the first storage box 7 and the second storage box 9 when they are fully closed, preventing the first storage box 7 and the second storage box 9 from dropping too much and causing damage to the connecting rods 6 on both sides. Driven by the first storage box 7, the second storage box 9 can be synchronously driven to move. When fully closed, the first storage box 7 supports the second storage box 9 and shields the first storage box 7, preventing foreign objects from entering the first storage box 7 and contaminating the potatoes, which may lead to inaccurate detection data.

[0035] Please refer to the appendix Figure 1 -appendix Figure 2 -appendix Figure 3 As shown in the figure, the first lid 10 is connected to the second storage box 9 through a hinge. A handle is provided on the outer wall of the first lid 10 for opening the second storage box 9.

[0036] Specifically, by pulling the handle provided on the outer wall of the first lid 10, the first lid 10 opens the second storage box 9 through the hinge, facilitating the placement and removal of potato samples inside the second storage box 9, and preventing foreign objects from entering the second storage box 9 and contaminating the potatoes, which may lead to inaccurate detection data.

[0037] Please refer to the appendix Figure 5 -appendix Figure 8 As shown in the figure, a first acceleration gear 11 is fixedly connected to the middle of the outer wall of the first through shaft 4. The tooth end of the first acceleration gear 11 is meshed with a second acceleration gear 12. A connecting shaft 13 is fixedly connected to the inner wall of the second acceleration gear 12. A cross plate 14 is rotatably connected to the outer wall of the connecting shaft 13. A first bevel gear 15 is fixedly connected to the outer wall of the connecting shaft 13. The tooth end of the first bevel gear 15 is meshed with a second bevel gear 16. A second through shaft 17 is fixedly connected to the inner wall of the second bevel gear 16. A first connecting box 18 is fixedly connected to the outer wall of the bottom case 1. A second connecting box 19 is fixedly connected to the outer wall of the first connecting box 18. The inner wall of the second connecting box 19 is rotatably connected to the outer wall of the second through shaft 17. A first helical gear 20 is fixedly connected to the outer wall of the second through shaft 17. A fixing column 21 is rotatably connected to the outer wall of the second through shaft 17. A second helical gear 22 is rotatably connected to the outer wall of the fixing column 21. A threaded column 23 is fixedly connected to the outer wall of the second helical gear 22. A limiting plate 24 is fixedly connected to the inner wall of the second connecting box 19. A moving plate 25 is threadedly connected to the outer wall of the threaded column 23. A weighing mechanism 26 is provided on the upper surface of the moving plate 25. A second lid 27 is rotatably connected to the inner and outer walls of the threaded column 23. The outer wall of the second lid 27 is arranged on the upper surface of the second connecting box 19.

[0038] Specifically, when the motor 3 drives the through-shaft one 4 to drive the linkage gear 5 to rotate to control the opening and closing of the first storage box 7 and the second storage box 9, it will also synchronously drive the first acceleration gear 11 to rotate. While using the motor 3 as the driving source to drive the opening and closing of the first storage box 7 and the second storage box 9, it can also synchronously drive the first acceleration gear 11 to rotate, thereby driving the second acceleration gear 12 meshing with the first acceleration gear 11 to rotate. The number of teeth of the first acceleration gear 11 is greater than that of the second acceleration gear 12, which has the effect that when the number of turns of the motor 3 driving the through-shaft one 4 to rotate is small, the second acceleration gear 12 can still rotate many turns, thereby driving the connecting shaft 13 and the first bevel gear 15 to rotate. Through the meshing of the first bevel gear 15 and the second bevel gear 16, the through-shaft two 17 is driven to rotate, and through the first bevel gear 15 and the second bevel gear 16, the direction of rotation is changed from vertical rotation to horizontal rotation, so that the through-shaft two 17 drives the first helical gear 20 to rotate, causing the first helical gear 20 to drive the second helical gear 22 to rotate. Through the cooperation of the first helical gear 20 and the second helical gear 22, the horizontal rotation is converted into vertical rotation, which can drive other components to move vertically up and down, and then drive the threaded column 23 to rotate. The rotation of the threaded column 23 drives the moving plate 25 to move on the inner wall of the second connecting box 19. Through the meshing of the threaded column 23 and the moving plate 25, the moving plate 25 is driven to move, and then the weighing mechanism 26 extends out of the inner wall of the second connecting box 19, taking out the potatoes stored in the first storage box 7 and the second storage box 9 for a period of time and placing them above the weighing mechanism 26 for weighing. The weighing mechanism 26 is a prior art and will not be elaborated too much. The storage characteristics of the potatoes are evaluated according to the weight before storage and the measured mass, achieving the effect that the weighing mechanism 26 can be stored inside the second connecting box 19 when not in use, which can avoid the weighing mechanism 26 being interfered with and damaged by external factors and effectively utilize the space inside the device, making the structure of the device more compact and reasonable.

[0039] Please refer to the attached Figure 5 and attached Figure 6 Figure, the outer wall of the horizontal plate 14 is fixedly connected to the inner wall of the bottom shell 1, and the outer wall of the through-shaft two 17 is rotatably connected to the inner wall of the bottom shell 1.

[0040] Specifically, by fixing the horizontal plate 14 inside the bottom shell 1, the horizontal plate 14 plays a role in limiting the position of the connecting shaft 13, preventing the connecting shaft 13 from falling, and at the same time ensuring that the second acceleration gear 12 is always meshed with the first acceleration gear 11.

[0041] Please refer to the attached Figure 7 and attached Figure 8 Figure, the outer wall of the fixed column 21 is fixedly connected to the inner wall of the bottom shell 1, and the tooth ends of the first helical gear 20 are meshed with the tooth ends of the second helical gear 22.

[0042] Specifically, by fixing the fixed column 21 on the inner wall of the bottom case 1, while supporting the second helical gear 22, it also supports and positions the second through shaft 17, preventing the second through shaft 17 from falling downward. Through the meshing connection between the first helical gear 20 and the second helical gear 22, the lateral rotation of the second through shaft 17 is converted into vertical rotation.

[0043] Please refer to the appendix Figure 8 , the inner wall of the limit plate 24 is rotatably connected to the outer wall of the second helical gear 22, and the inner wall of the traveling plate 25 is threadedly connected to the inner wall of the threaded column 23.

[0044] Specifically, through the rotational connection between the limit plate 24 and the second helical gear 22, it plays a role in limiting and supporting the position of the second helical gear 22. While preventing the second helical gear 22 from moving under the force of the first helical gear 20, it also ensures that the second helical gear 22 does not fall downward.

[0045] Please refer to the appendix Figure 2 , appendix Figure 5 and appendix Figure 7 , the second box cover 27 is connected to the second connecting box 19 through a hinge. A handle is provided on the upper surface of the second box cover 27, and the handle is used to open the second connecting box 19.

[0046] Specifically, by pulling the handle, the second connecting box 19 is opened, which is convenient for placing potatoes inside for storage. When closed, it also prevents foreign objects from entering the inside of the second connecting box 19 and contaminating the potatoes, thus affecting the measurement result data.

[0047] Please refer to the appendix Figure 1 and appendix Figure 2 , when the first storage box 7 and the second storage box 9 are fully opened, the weighing mechanism 26 extends out of the inside of the second connecting box 19. When the first storage box 7 and the second storage box 9 are fully closed, the weighing mechanism 26 is located inside the second connecting box 19.

[0048] Specifically, when the first storage box 7 and the second storage box 9 are fully opened, at this time, the potatoes inside the first storage box 7 and the second storage box 9 are completely exposed, and the weighing mechanism 26 is also in an exposed state at this time. It can directly weigh the potatoes in the first storage box 7 and the second storage box 9 to detect the storage characteristics of the potatoes.

[0049] Please refer to the appendix Figure 1 - appendix Figure 8, A measurement method for a potato storage tolerance measurement device, which is used for a potato storage tolerance measurement device according to any one of claims 1-9, comprising the following steps: First, start the motor 3 to drive the through shaft one 4 to rotate, and then drive the linkage gear 5 and the connecting rod one 6 to rotate synchronously, so that the linkage gear 5 and the connecting rod one 6 on the other side also rotate synchronously. Then, make the two connecting rods one 6 rotate with the through shaft one 4 as the central axis. Push the two storage boxes one 7 to move towards each other and to both sides by the force of the rotation of the connecting rod one 6. While the connecting rod one 6 drives the storage box one 7 to move, the storage box one 7 drives the connecting rod two 8 to rotate with the part where the connecting rod two 8 is connected to the bottom shell 1 as the central axis, and then drives the storage box two 9 and the storage box one 7 to move towards each other and to both sides. Open the storage box two 9 by pulling the handle on the box cover one 10, place the potatoes to be stored for the experiment inside the storage box one 7 and the storage box two 9, pull the handle to cover the storage box two 9, and then start the motor 3 to drive the linkage gear 5 to rotate in the reverse direction, so that the storage box one 7 and the storage box two 9 return to their original positions;

[0050] When the motor 3 drives the through shaft one 4 to drive the linkage gear 5 to rotate to control the opening and closing of the storage box one 7 and the storage box two 9, it will also synchronously drive the acceleration gear one 11 to rotate, and then drive the acceleration gear two 12 meshing with the acceleration gear one 11 to rotate, thereby driving the connecting shaft 13 and the bevel gear one 15 to rotate. Through the meshing of the bevel gear one 15 and the bevel gear two 16, drive the through shaft two 17 to rotate, and then drive the helical gear one 20 to rotate through the through shaft two 17, so that the helical gear one 20 drives the helical gear two 22 to rotate, and then drive the threaded column 23 to rotate. The rotation of the threaded column 23 drives the moving plate 25 to move on the inner wall of the connecting box two 19. When the storage box one 7 and the storage box two 9 are fully opened and closed, the weighing mechanism 26 extends out of the inner wall of the connecting box two 19. When the storage box one 7 and the storage box two 9 are fully closed, the weighing mechanism 26 is inside the connecting box two 19. Take out the potatoes stored in the storage box one 7 and the storage box two 9 for a period of time and place them above the weighing mechanism 26 for weighing, and evaluate the storage characteristics of the potatoes according to the weight before storage and the measured mass.

[0051] Specifically, the starting motor 3 drives the first through-shaft 4 to rotate. Using the motor 3 as the driving source, the other components are driven to rotate, thereby driving the linkage gear 5 and the first connecting rod 6 to rotate synchronously. Through the meshing of the linkage gears 5 on both sides, the linkage gear 5 and the first connecting rod 6 on the other side also rotate synchronously. Then, with the first through-shaft 4 as the central axis, the first connecting rods 6 on both sides rotate to push the first storage boxes 7 on both sides to move towards each other. Driven by the thrust of the first connecting rod 6, the first storage box 7 and the second storage box 9 move synchronously, so that the first storage box 7 and the second storage box 9 are opened. While the first connecting rod 6 drives the first storage box 7 to move, the first storage box 7 drives the second connecting rod 8 to rotate with the part where the second connecting rod 8 is connected to the bottom case 1 as the central axis. Driven by the force of the movement of the first storage box 7, the second connecting rod 8 moves, causing the second connecting rod 8 to rotate. Then, it drives the second storage box 9 and the first storage box 7 to move towards each other. By pulling the handle provided on the outer wall of the first box cover 10, the first box cover 10 opens the second storage box 9 through the hinge, which facilitates placing and taking out potato samples inside the second storage box 9. Also, it prevents foreign objects from entering the second storage box 9 and contaminating the potatoes, which may lead to inaccurate test data. By starting the motor 3 to drive the linkage gear 5 to rotate in the reverse direction, the first storage box 7 and the second storage box 9 are reset. When a certain potato sample is diseased or rotten, it is not easy to quickly spread to other potatoes, thus avoiding large-scale cross-infection and quality degradation, and ensuring the accuracy and reliability of the experimental results;

[0052] When the motor 3 drives the through shaft 1 to drive the linkage gear 5 to rotate to control the opening and closing of the first storage box 7 and the second storage box 9, it will also synchronously drive the first acceleration gear 11 to rotate. While using the motor 3 as the driving source to drive the opening and closing of the first storage box 7 and the second storage box 9, it can also synchronously drive the first acceleration gear 11 to rotate. By fixing the cross plate 14 inside the bottom shell 1, the cross plate 14 plays a role in limiting the position of the connecting shaft 13. While preventing the connecting shaft 13 from falling, it also ensures that the second acceleration gear 12 is always meshed with the first acceleration gear 11, thereby driving the second acceleration gear 12 meshed with the first acceleration gear 11 to rotate. Among them, the number of teeth of the first acceleration gear 11 is greater than that of the second acceleration gear 12, which has the effect that when the number of turns of the motor 3 driving the through shaft 1 to rotate is small, the second acceleration gear 12 can still rotate many turns, thereby driving the connecting shaft 13 and the first bevel gear 15 to rotate. Through the meshing of the first bevel gear 15 and the second bevel gear 16, the through shaft 2 is driven to rotate. Through the first bevel gear 15 and the second bevel gear 16, the direction of rotation is changed from vertical rotation to horizontal rotation, thereby driving the first helical gear 20 to rotate through the through shaft 2. The first helical gear 20 drives the second helical gear 22 to rotate. By fixing the fixed column 21 on the inner wall of the bottom shell 1, while supporting the second helical gear 22, it also supports and limits the through shaft 2 to prevent the through shaft 2 from falling downward. Through the cooperation of the first helical gear 20 and the second helical gear 22, the horizontal rotation is converted into vertical rotation, which can drive other components to move vertically up and down, thereby driving the threaded column 23 to rotate. The rotation of the threaded column 23 drives the moving plate 25 to move on the inner wall of the second connecting box 19. Through the meshing of the threaded column 23 and the moving plate 25, the moving plate 25 is driven to move, thereby causing the weighing mechanism 26 to extend out of the inner wall of the second connecting box 19, taking out the potatoes stored in the first storage box 7 and the second storage box 9 for a period of time, placing them above the weighing mechanism 26 for weighing, and evaluating the storage characteristics of the potatoes according to the weight before storage and the measured mass. When the weighing mechanism 26 is not in use, it can be stored inside the second connecting box 19, which can avoid the weighing mechanism 26 being interfered with and damaged by external factors and effectively utilize the space inside the device, making the structure of the device more compact and reasonable.

10. A determination method for a potato storage tolerance characteristic determination device, characterized in that, For a potato storage resistance characteristic measuring device according to any one of claims 1-9, the following steps are included: First, start the motor (3) to drive the first through shaft (4) to rotate, thereby driving the linkage gear (5) and the first connecting rod (6) to rotate synchronously, so that the linkage gear (5) and the first connecting rod (6) on the other side also rotate synchronously, and then make the first connecting rods (6) on both sides rotate with the first through shaft (4) as the central axis. The force of the rotation of the first connecting rod (6) is used to push the first storage boxes (7) on both sides to move towards each other and move to both sides. While the first connecting rod (6) drives the first storage box (7) to move, the first storage box (7) drives the second connecting rod (8) to rotate with the part where the second connecting rod (8) is connected to the bottom shell (1) as the central axis, thereby driving the second storage box (9) and the first storage box (7) to move towards each other and move to both sides. Open the second storage box (9) by pulling the handle on the first box cover (10), place the potatoes to be stored for experiments in the first storage box (7) and the second storage box (9), pull the handle to cover the second storage box (9), and then drive the linkage gear (5) to rotate in the reverse direction by starting the motor, so that the first storage box (7) and the second storage box (9) return to their original positions; When the motor (3) drives the through shaft one (4) to drive the linkage gear (5) to rotate to control the opening and closing of the storage box one (7) and the storage box two (9), it will also synchronously drive the acceleration gear one (11) to rotate, and then drive the acceleration gear two (12) meshing with the acceleration gear one (11) to rotate, thereby driving the connecting shaft (13) and the bevel gear one (15) to rotate. Through the meshing of the bevel gear one (15) and the bevel gear two (16), the through shaft two (17) is driven to rotate, and thus the helical gear one (20) is driven to rotate by the through shaft two (17), so that the helical gear one (20) drives the helical gear two (22) to rotate, and then drives the threaded column (23) to rotate. The rotation of the threaded column (23) drives the traveling plate (25) to move on the inner wall of the connecting box two (19). When the storage box one (7) and the storage box two (9) are completely opened and closed, the weighing mechanism (26) extends out of the inner wall of the connecting box two (19). When the storage box one (7) and the storage box two (9) are completely closed, the weighing mechanism (26) is inside the connecting box two (19). Take out the potatoes stored in the storage box one (7) and the storage box two (9) for a period of time, place them above the weighing mechanism (26) for weighing, and evaluate the storage characteristics of the potatoes according to the weight before storage and the measured mass.
