Description

Technical Field

[0001] This invention relates to the field of Chinese medicinal materials, and in particular to a device and method for cold storage of Chinese medicinal materials. Background Technology

[0002] With the continuous advancement of science and technology, the production technology of Chinese medicinal herbs has made significant progress. Before being put into production, Chinese medicinal herbs need to be preserved to prevent natural damage and waste. The common method of preserving Chinese medicinal herbs is through low-temperature refrigeration. The herbs are placed in storage boxes and then stacked in a cold storage room to protect them. While this method effectively prevents natural damage, the stacking method is relatively traditional. The bottom layer of boxes is in contact with the ground and is easily damaged by moisture, so additional moisture-proof mats are needed, increasing storage costs. Stacking can also cause the herbs to be squeezed, and people need to constantly enter and exit the cold storage room during the stacking process. Working in the low-temperature environment may cause frostbite.

[0003] Therefore, based on the above problems, we are now developing a cold storage device for preserving Chinese medicinal materials that allows for easy layering and storage of Chinese medicinal materials while reducing the time people spend working in low-temperature environments. Summary of the Invention

[0004] To overcome the drawbacks of existing devices that easily damage Chinese medicinal materials by directly stacking them, and the potential for frostbite to people working in low-temperature environments for extended periods, a cold storage device for preserving Chinese medicinal materials is provided that allows for easy layering of Chinese medicinal materials while reducing the time people spend working in low-temperature environments.

[0005] The technical solution is as follows: A cold storage device for preserving Chinese medicinal materials includes a cold storage room, a refrigeration module, a maintenance door, an automatic removal mechanism, and an inner wall cleaning mechanism. The refrigeration module is connected to the top of the cold storage room, and the maintenance door is rotatably connected to the rear side of the cold storage room. The cold storage room is equipped with an automatic removal mechanism that can automatically remove medicinal materials, making it convenient for people to place them. The cold storage room is also equipped with an inner wall cleaning mechanism that scrapes and cleans the inner wall.

[0006] As a further preferred embodiment, the automatic removal mechanism includes a guide seat, a first servo motor, a first lead screw, and a shelf. Three guide seats are connected to the front bottom of the cold storage. The rear side of each guide seat is bolted to a first servo motor. The output shaft of each first servo motor is connected to a first lead screw via a coupling. A shelf is slidably connected to each guide seat, and each shelf is threadedly connected to the corresponding first lead screw.

[0007] As a further preferred embodiment, the inner wall cleaning mechanism includes a protective seat, a second servo motor, a second lead screw, a guide bracket, and a scraper. The protective seat is connected to the middle position of the rear side of the bottom of the cold storage. The second servo motor is bolted to the bottom of the protective seat. The second lead screw is connected to the output shaft of the second servo motor. The guide bracket is connected to the right side of the protective seat. The scraper is slidably connected to the guide bracket. The scraper is threadedly connected to the second lead screw.

[0008] As a further preferred embodiment, it also includes a leveling mechanism for aligning and tidying the Chinese herbal medicine storage box. The leveling mechanism includes a guide frame, a wedge-shaped groove frame, a pusher, a leveling component, and a return spring. The guide frame is bolted to both sides of the guide seat. The wedge-shaped groove frame is slidably connected to each guide frame. The pusher is connected to both sides of the rear of the shelf. Multiple leveling components are slidably connected to each wedge-shaped groove frame. A return spring is connected between each leveling component and the wedge-shaped groove frame.

[0009] As a further preferred embodiment, it also includes a flow guiding mechanism for guiding water droplets and ice adhering to the inner wall of the cold storage. The flow guiding mechanism includes a mounting bracket, a torsion spring, a flow guiding component, a first rotating component, and a pressing component. Four mounting brackets are connected to the bottom of the cold storage. Two first rotating components are rotatably connected to each mounting bracket. A flow guiding component is connected between each pair of first rotating components. A torsion spring is connected between each first rotating component and the mounting bracket. Multiple pressing components are connected to the scraping component.

[0010] As a further preferred embodiment, it also includes an auxiliary moving mechanism for supporting and assisting the movement of the shelf. The auxiliary moving mechanism includes a first mounting block, a second rotating component, a synchronous transmission assembly, a guide slot, a second mounting block, and a moving wheel. Two first mounting blocks are connected to the lower rear side of the shelf, and a second rotating component is rotatably connected to each of the first mounting blocks. Guide slots are connected to the upper left and right sides of the guide seat, and each guide slot is slidably connected to the corresponding second rotating component. Two second mounting blocks are connected to the lower front side of the shelf, and a moving wheel is rotatably connected to each of the second mounting blocks. A synchronous transmission assembly is connected between each moving wheel and the second rotating component on the same side.

[0011] As a further preferred embodiment, it also includes a heating assembly for rapidly melting ice, the heating assembly including a mounting plate and a heating plate, the bottom of the scraper being connected to the mounting plate, and the heating plate being connected to the mounting plate.

[0012] As a further preferred option, each shelf has ventilation slots to reduce the possibility of medicinal materials getting damp when stacked.

[0013] As a further preferred option, the flow guide is made of an elastic material, which can cushion the ice while preventing the flow guide itself from being damaged by impact.

[0014] A method for using a cold storage device for preserving Chinese medicinal herbs:

[0015] Step 1: Start the first servo motor to make the shelf slide forward. As the shelf slides out, the moving wheels will rotate counterclockwise to support the shelf. Then place the Chinese herbal medicine storage box on the shelf.

[0016] Step 2: As the shelf slides back to its original position, the leveling components will push the Chinese herbal medicine storage box, making it more level and less likely to fall off.

[0017] Step 3: During daily operation, the second servo motor and heating plate need to be activated so that the scraper can quickly scrape and clean the inner wall of the cold storage, preventing water droplets and ice from adhering and affecting the storage of Chinese medicinal materials. The scraped water droplets and ice will be collected in the inner edge groove of the cold storage under the guidance of the guide.

[0018] Step 4: If a component inside the cold storage malfunctions and repairs are needed, simply open the maintenance door to perform the maintenance.

[0019] Compared with the prior art, the present invention has the following advantages: 1. The present invention drives the first lead screw to rotate through the first servo motor, thereby making the shelf slide automatically, which facilitates people to quickly place Chinese medicinal materials, reduces the working time of people in the cold storage, avoids frostbite, and the layered design of the shelf can prevent Chinese medicinal materials from being piled together, reducing the possibility of Chinese medicinal materials getting damp or crushed.

[0020] 2. The present invention drives the second lead screw to rotate by rotating the output shaft of the second motor, thereby causing the scraping part to slide and scrape and clean the inner wall of the cold storage, thus avoiding the accumulation of a large amount of water droplets and ice on the inner wall of the cold storage, which could cause the Chinese medicinal materials to become damp and damaged.

[0021] 3. This invention uses the interaction between the leveling component and the return spring to push the boxes of Chinese medicinal materials that are not neatly arranged on the shelf, thereby making the Chinese medicinal materials more evenly placed and preventing the boxes from falling and causing damage to the Chinese medicinal materials.

[0022] 4. The present invention drives the synchronous transmission assembly to rotate through the rotation of the second rotating component, thereby causing the moving wheel to rotate counterclockwise, which in turn supports the shelf and assists the shelf to slide forward, making the sliding of the shelf more stable and convenient.

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] A device and method for cold storage of Chinese medicinal materials, such as Figures 1-5 As shown, it includes a cold storage 1, a refrigeration module 2, a maintenance door 3, an automatic removal mechanism 4, and an inner wall cleaning mechanism 5. The top of the cold storage 1 is connected to the refrigeration module 2, which is used to cool the interior of the cold storage 1. The rear of the cold storage 1 is rotatably connected to the maintenance door 3, which facilitates maintenance of the internal components of the cold storage 1. The cold storage 1 is equipped with an automatic removal mechanism 4, which can automatically remove medicinal materials, making it convenient for people to place them. The cold storage 1 is equipped with an inner wall cleaning mechanism 5, which can scrape and clean the inner wall of the cold storage 1.

[0044] After harvesting, Chinese medicinal herbs need to be centrally stored to prevent natural damage. Low-temperature storage is commonly used to protect them. This device facilitates low-temperature storage of medicinal herbs. In operation, the refrigeration module 2 is first activated to cool the interior of the cold storage 1. Then, the automatic removal mechanism 4 is activated to sort and place the herbs. After placement, the automatic removal mechanism 4 is reset. As the cold storage 1 is used over time, water droplets or ice may accumulate on its inner walls. At this point, the inner wall cleaning mechanism 5 can be activated to clean the inner walls of the cold storage 1, preventing water droplets from forming. Alternatively, ice may remain attached, reducing the cooling effect and preventing the medicinal materials from getting damp. If maintenance is needed on the internal components of the cold storage 1, the maintenance door 3 can be opened, allowing direct access to the cold storage 1 for inspection. In summary, by using the automatic removal mechanism 4 to classify and stack the medicinal materials, it is easier for people to place them, reducing the time people spend directly entering the cold storage 1 and preventing frostbite from prolonged work inside the cold storage 1. At the same time, the internal wall cleaning mechanism 5 can quickly clean the internal walls of the cold storage 1, preventing a large amount of water droplets or ice from adhering to the walls and preventing the medicinal materials from getting damp.

[0045] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the automatic removal mechanism 4 includes a guide seat 41, a first servo motor 42, a first lead screw 43, and a shelf 44. Three guide seats 41 are connected to the front bottom of the cold storage 1. The rear side of each guide seat 41 is connected to a first servo motor 42 by bolts. The first servo motor 42 can provide running power. The output shaft of the first servo motor 42 is connected to the first lead screw 43 by a coupling. The shelf 44 is slidably connected to each guide seat 41. The shelf 44 is threadedly connected to the corresponding first lead screw 43. The shelf 44 is multi-layered, which facilitates the classification and placement of medicinal materials and avoids direct stacking of medicinal materials. Each layer of the shelf 44 has a ventilation groove, which can reduce the possibility of the medicinal materials getting damp when stacked.

[0046] When placing the Chinese herbal medicine storage boxes, the first servo motor 42 can be activated based on the number of boxes to be placed. If there are many boxes, all servo motors 42 should be activated; if there are few boxes, only one servo motor 42 needs to be activated. Activating the servo motor 42 will drive the first lead screw 43 to rotate, causing the corresponding shelf 44 to slide forward. Once the shelf 44 has fully slid out, the first servo motor 42 should be deactivated. The Chinese herbal medicine storage boxes can then be placed on the shelf 44 for categorized placement. Simultaneously, the ventilation slots on the shelf 44... This design avoids the problem of insufficient ventilation when placing Chinese medicinal herbs in storage boxes, which could lead to moisture damage. After the storage boxes are placed, the output shaft of the first servo motor 42 is reversed, causing the first lead screw 43 to rotate in the opposite direction. This causes the corresponding shelf 44 to slide back and reset. Once the shelf 44 is fully reset, the first servo motor 42 is turned off. In summary, the first servo motor 42 drives the first lead screw 43 to rotate, causing the shelf 44 to slide automatically. This facilitates quick placement of Chinese medicinal herbs. At the same time, the layered design of the shelf 44 prevents the herbs from being piled up, reducing the possibility of moisture damage or crushing.

[0047] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the inner wall cleaning mechanism 5 includes a protective seat 51, a second servo motor 52, a second lead screw 53, a guide bracket 54, and a scraper 55. The protective seat 51 is connected to the middle position of the rear side of the bottom of the cold storage 1. The second servo motor 52 is connected to the bottom of the protective seat 51 by bolts. The protective seat 51 can protect the second servo motor 52. The second lead screw 53 is connected to the output shaft of the second servo motor 52. The guide bracket 54 is connected to the right side of the protective seat 51. The scraper 55 is slidably connected to the guide bracket 54. The scraper 55 is threadedly connected to the second lead screw 53. The scraper 55 has a C-shaped design and can scrape and clean the inner wall of the cold storage 1.

[0048] When the cold storage 1 is in a refrigerated state for a long time, ice will gradually form on the inner wall of the cold storage 1. With the opening and closing of the shelf 44 or the maintenance door 3, a large amount of water droplets will appear on the inner wall of the cold storage 1. If not cleaned in time, the Chinese medicinal materials are easily damaged by moisture. Therefore, the second servo motor 52 is started. The output shaft of the second servo motor 52 drives the second lead screw 53 to rotate, thereby causing the scraper 55 to begin to slide downward. During the downward sliding process of the scraper 55, the guide bracket 54 will guide the scraper 55 to slide, making the scraper 55 more stable during the sliding process. As the scraper 55 begins to slide downward... Sliding downwards will scrape away water droplets or ice, causing them to fall into the inner edge groove of the cold storage 1. When the scraper 55 reaches its bottom limit, the second servo motor 52 is turned off. If it is necessary to continue cleaning the inner wall of the cold storage 1, the above operation can be repeated. After cleaning, the second servo motor 52 is turned off. In summary, the output shaft of the second servo motor 52 rotates, driving the second lead screw 53 to rotate, thereby causing the scraper 55 to start sliding, thus scraping and cleaning the inner wall of the cold storage 1, preventing a large amount of water droplets and ice from adhering to the inner wall of the cold storage 1, which could cause the Chinese medicinal materials to become damp and damaged.

[0049] like Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, it also includes a leveling mechanism 6, which includes a guide frame 61, a wedge-shaped groove frame 62, a pusher 63, a leveling component 64, and a return spring 65. The guide seat 41 is bolted to both sides of the guide frame 61, and the wedge-shaped groove frame 62 is slidably connected to each guide frame 61. The rear left and right sides of the shelf 44 are connected to pushers 63, which are slidably connected to their corresponding guide groove frames 84. Multiple leveling components 64 are slidably connected to each wedge-shaped groove frame 62. Six leveling components 64 are slidably connected to the frame 62. The two leveling components 64 on the left and right interact with each other to push and align the placed Chinese medicine boxes, avoiding uneven placement. Each leveling component 64 is connected to a return spring 65. The return springs 65 are all wrapped around the wedge-shaped groove frame 62. The end of the return spring 65 on each pair of left and right symmetrical wedge-shaped groove frames 62 that is close to each other is connected to the leveling component 64, and the end that is far away from each other is connected to the wedge-shaped groove frame 62.

[0050] As the shelf 44 slides forward, it drives the pushing component 63 forward, which in turn pushes the wedge-shaped groove frame 62 to slide away from each other. This causes the leveling component 64 to move away from the shelf 44. When a box containing Chinese medicinal herbs is placed on the shelf 44, and then the shelf 44 slides back to its original position, the pushing component 63 slides along the wedge-shaped groove frame 62, pulling the wedge-shaped groove frame 62 towards the shelf 44. This, in turn, causes the leveling component 64 to move towards the shelf 44. When the leveling component 64... When the herbal medicine storage box comes into contact with the material, it will be pushed, making the box more level. During this process, the leveling component 64 that comes into contact with the box will slide, causing the return spring 65 to be compressed. Then, under the action of the return spring 65, the leveling component 64 is pushed back to its original position. In summary, through the interaction between the leveling component 64 and the return spring 65, the herbal medicine storage boxes that are not placed neatly on the shelf 44 are pushed, making them more level and preventing them from falling and causing damage to the herbs.

[0051] like Figure 3 , Figure 4 , Figure 11 , Figure 12 and Figure 13 As shown, it also includes a flow guiding mechanism 7, which includes a mounting bracket 71, a torsion spring 72, a flow guiding component 73, a first rotating component 74, and a pressing component 75. Four mounting brackets 71 are connected to the bottom of the cold storage 1, two mounting brackets 71 are connected to the rear side of the bottom, and one mounting bracket 71 is connected to each of the left and right sides of the bottom. Two first rotating components 74 are rotatably connected to each mounting bracket 71, and a flow guiding component 73 is connected between each pair of first rotating components 74. The flow guiding component 73 can guide the scraped water droplets or ice. The buffer guide ensures that water droplets or ice cubes enter the inner edge groove of the cold storage 1. The guide 73 is made of elastic material, which can buffer the ice cubes while preventing the guide 73 itself from being damaged by impact. Torsion springs 72 are connected between the first rotating part 74 and the mounting bracket 71. The torsion springs 72 are all wrapped around the first rotating part 74. Multiple pressing parts 75 are connected to the scraper 55. There are eight pressing parts 75 in total, which correspond to the first rotating part 74 respectively. The pressing parts 75 can squeeze and push the first rotating part 74.

[0052] As the scraper 55 begins to scrape and clean the inner wall of the cold storage 1, the scraped water droplets or ice cubes fall directly onto the guide 73. The water droplets flow into the inner edge groove of the cold storage 1 along the guide 73, while the ice cubes remain on the guide 73. As the scraper 55 moves downward, the pressing parts 75 also move downward. When the pressing parts 75 contact the first rotating part 74, the first rotating part 74 is squeezed by the pressing parts 75 and rotates, causing the torsion spring 72 to deform. At this time, the guide 73 rotates towards the side closer to the mounting bracket 71, thereby guiding the ice cubes. Inside the inner edge groove of the cold storage 1, as the scraper 55 moves upward and resets, the first rotating part 74 is no longer squeezed by the pressing part 75. Under the action of the torsion spring 72, the first rotating part 74 will rotate and reset, thereby driving the guide part 73 to rotate and reset to the side away from the mounting bracket 71. In summary, the guide part 73 guides the falling water droplets to ensure that the water droplets can enter the inner edge groove of the cold storage 1. At the same time, the guide part 73 can also buffer the falling ice blocks to prevent the ice blocks from falling directly into the water and splashing water, causing water to accumulate at the bottom of the cold storage 1 and affecting maintenance work.

[0053] like Figure 5 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, it also includes an auxiliary moving mechanism 8, which includes a first mounting block 81, a second rotating component 82, a synchronous transmission assembly 83, a guide slot frame 84, a second mounting block 85, and a moving wheel 86. Two first mounting blocks 81 are connected to the lower rear side of the shelf 44, and the first mounting blocks 81 are symmetrically distributed left and right. A second rotating component 82 is rotatably connected to each first mounting block 81. Guide slot frames 84 are connected to the upper left and right sides of the guide seat 41. The guide slot frames 84 are all Z-shaped designs, and each guide slot frame 84 is slidably connected to the corresponding second rotating component 82. Two second mounting blocks 85 are connected to the lower front side of each shelf 44. The second mounting blocks 85 are symmetrically distributed on the left and right. Each second mounting block 85 is rotatably connected to a movable wheel 86. The movable wheel 86 can support the shelf 44 and assist the shelf 44 in moving. A synchronous transmission assembly 83 is connected between the movable wheel 86 and the second rotating member 82 on the same side. The synchronous transmission assembly 83 includes two transmission wheels and a transmission belt. One transmission wheel is connected to the movable wheel 86, and the other transmission wheel is connected to the second rotating member 82. The transmission belt is wound between the transmission wheels.

[0054] As the shelf 44 begins to slide forward, the second rotating members 82 slide along the guide groove 84, causing them to rotate counterclockwise. This, in turn, activates the synchronous transmission assembly 83, which drives the moving wheels 86 to rotate counterclockwise, thus supporting the shelf 44 and assisting it in sliding forward. This makes the shelf 44 more stable and easier to move. After the medicinal herbs are placed, the shelf 44 slides back to its original position. The second rotating component 82 will move backward to reset. Under the guidance of the guide slot frame 84, the second rotating component 82 will rotate clockwise to reset. The second rotating component 82 will drive the synchronous transmission component 83 to operate, thereby causing the moving wheel 86 to rotate clockwise to reset. In summary, by rotating the second rotating component 82 to drive the synchronous transmission component 83 to operate, the moving wheel 86 will rotate counterclockwise, thereby supporting the shelf 44 and assisting the shelf 44 to slide forward, making the sliding of the shelf 44 more stable and convenient.

[0055] like Figure 3 , Figure 4 and Figure 18 As shown, it also includes a heating component 9, which includes a mounting plate 91 and a heating plate 92. The bottom of the scraper 55 is connected to the mounting plate 91, and the mounting plate 91 is connected to the heating plate 92. The heating plate 92 can heat up to melt the ice and make it easier to scrape and clean.

[0056] When scraping and cleaning the inner wall of the cold storage 1, the heating plate 92 can be activated to melt the ice quickly, making it easier for the scraper 55 to clean the ice, reducing the difficulty of cleaning, and avoiding damage to the scraper 55. After cleaning, the heating plate 92 can be turned off.

[0057] A method for using a cold storage device for preserving Chinese medicinal herbs:

[0058] Step 1: Start the first servo motor 42 to make the shelf 44 slide forward. As the shelf 44 slides out, the moving wheels 86 will rotate counterclockwise to support the shelf 44. Then place the Chinese herbal medicine storage box on the shelf 44.

[0059] Step 2: As the shelf 44 slides back to its original position, the leveling component 64 will push the Chinese herbal medicine storage box, making the Chinese herbal medicine storage box more level and less likely to fall off.

[0060] Step 3: During daily operation, the second servo motor 52 and heating plate 92 need to be activated so that the scraper 55 can quickly scrape and clean the inner wall of the cold storage 1 to prevent water droplets and ice from adhering and affecting the storage of Chinese medicinal materials. The scraped water droplets and ice will be collected in the inner edge groove of the cold storage under the guidance of the guide 73.

[0061] Step 4: If a component inside the cold storage 1 malfunctions and repairs are required, simply open the maintenance door 3 to perform the maintenance.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
