Description

Technical Field

[0001] This utility model relates to the field of drying and processing technology for Chinese medicinal materials after planting, and specifically to a drying rack for planting Chinese medicinal materials. Background Technology

[0002] The drying process after harvesting Chinese medicinal herbs is a crucial step in ensuring their quality and medicinal value. Freshly picked herbs have a high moisture content, and without drying, they are highly susceptible to mold and rot due to microbial growth, severely impacting their medicinal efficacy. Drying not only effectively removes excess moisture and inhibits bacterial and mold growth, significantly extending the shelf life of the herbs, but also reduces their volume and weight, facilitating storage and transportation and greatly reducing warehousing and logistics costs. More importantly, during the drying process, some of the chemical components within the herbs undergo transformation, promoting the further accumulation of active ingredients and enhancing their medicinal effects.

[0003] According to the patent authorization announcement number (CN221859062U), a drying rack for processing Chinese medicinal materials includes a U-shaped frame with several equidistant parallel drying boards installed inside. The structure disclosed in this patent has defects in practical application, specifically as follows: its design of using multiple drying boards for open-air drying makes it difficult to withstand the threat of sudden rainfall. In nature, some rainfall events are extremely sudden and instantaneous, pouring down without warning. Workers cannot easily move the large frame indoors for shelter in a short time. At this time, rainwater will pour onto each drying board without any cover, causing large areas of the Chinese medicinal materials to become soaked. Once the medicinal materials become damp, they will not only mold and deteriorate, reducing their medicinal efficacy, but may even completely lose their usability, seriously affecting the drying results and the quality of the medicinal materials. This design has significant deficiencies in terms of rain protection and emergency response. Utility Model Content

[0004] The purpose of this utility model is to provide a drying rack for planting Chinese medicinal herbs. It addresses the problem that existing drying racks lack emergency protection measures against sudden rainfall, resulting in large-scale soaking of Chinese medicinal herbs during unpredictable heavy rain. The present invention provides a solution that can effectively intercept the damage to Chinese medicinal herbs caused by sudden rainfall and prevent damage to the herbs due to failure to move the drying rack in time.

[0005] This utility model is achieved through the following technical solution:

[0006] A drying rack for planting Chinese medicinal herbs includes: a base unit with multiple casters mounted on its bottom; multiple support columns, all of which are detachably mounted on the base unit and enclose an assembly area; multiple medicinal herb holders, which are detachably mounted sequentially from top to bottom within the assembly area; a guide component installed inside one of the support columns and capable of reciprocating along the extension direction of the support column; and a foldable rainproof and protective assembly mounted on the support column. In rainy conditions, the foldable rainproof and protective assembly moves synchronously with the guide component to the outside of the support column, and the foldable rainproof and protective assembly extends to an extended state. In the drying state, the foldable rainproof and protective assembly moves synchronously with the guide component to the inside of the support column, and the foldable rainproof and protective assembly folds to a folded state.

[0007] Furthermore, in this utility model, the edge of the above-mentioned Chinese herbal medicine holder is equipped with multiple shaft sleeves along the circumferential direction, and the multiple shaft sleeves correspond one-to-one with multiple support columns; the shaft sleeves are provided with installation grooves, and positioning components are installed inside the installation grooves; the support columns are provided with multiple positioning slots along the extension direction that cooperate with the positioning components for positioning.

[0008] Furthermore, in this utility model, the positioning component includes a first positioning pin and a return spring; the return spring is sleeved on the outside of the first positioning pin and assembled inside the mounting groove. One end of the return spring is connected to the inner wall of the mounting groove, and the other end of the return spring is connected to the outer wall of the first positioning pin. The first positioning pin can be engaged into the positioning slot under the action of the return spring.

[0009] Furthermore, in this utility model, the guide component includes a guide portion and a connecting portion; the guide portion is internally guided and cooperates with the support column, and the guide portion can reciprocate along the extension direction of the support column. The guide portion is equipped with an assembly channel, and a limiting component is installed inside the assembly channel; the connecting portion has an L-shaped cross-section and connects to the foldable rainproof protective component; the support column has extension positioning holes and folding positioning holes sequentially opened from top to bottom; in the rainy state, the limiting component cooperates with the extension positioning holes to keep the foldable rainproof protective component in an extended state; in the drying state, the limiting component cooperates with the folding positioning holes to keep the foldable rainproof protective component in a folded state.

[0010] Furthermore, in this utility model, the aforementioned limiting component includes an elastic element and a limiting pin; one end of the elastic element is connected to the bottom of the assembly channel, and the other end of the elastic element is connected to the limiting pin; in the rainy state, the limiting pin engages with the extension positioning hole to keep the foldable rainproof protective component in an extended state; in the drying state, the limiting pin engages with the folding positioning hole to keep the foldable rainproof protective component in a folded state.

[0011] Furthermore, in this utility model, the aforementioned foldable rainproof protective assembly includes two first folding rods, two second folding rods, two first connectors, a second connector, and a flexible rainproof covering; one end of each of the two first folding rods is rotatably connected to the connecting part, and the ends of the two first folding rods away from the connecting part are respectively rotatably connected to different first connectors; one end of each of the two second folding rods is respectively rotatably connected to different first connectors, and the other end of each of the two second folding rods is rotatably connected to the same second connector; one edge of the rainproof covering is respectively connected to the inner surface of the two first folding rods, and the other edge of the rainproof covering is respectively connected to the inner surface of the two second folding rods.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] 1. This application utilizes a linkage mechanism between the foldable rain-proof component and the guide component. In the event of sudden rainfall, the foldable rain-proof component can be quickly removed from the support column and extended to form a complete rain barrier, effectively preventing large-scale soaking of medicinal herbs. This prevents the herbs from becoming moldy and deteriorating due to moisture, thus reducing their efficacy and greatly ensuring the drying results and quality of the herbs. It fundamentally solves the shortcomings of existing technologies in emergency rain protection.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0026] Example

[0027] Please refer to Figures 1 to 4 This utility model provides a drying rack for planting Chinese medicinal herbs. The base unit 1 is equipped with casters 2 at its bottom for convenient movement and precise positioning. Multiple support columns 3 are detachably installed in a matrix arrangement on the base unit 1, forming an assembly area. Multi-layered, perforated mesh-like medicinal herb racks 5 are stacked orderly from top to bottom within the assembly area. The number and spacing can be flexibly adjusted according to the drying scale to ensure the herbs are fully exposed to sunlight and have good ventilation.

[0028] One of the support columns 3 features a hollow interior with a guide component that slides axially. This guide component is connected to a foldable rain-proof and protective assembly. In the event of sudden rainfall, the guide component slides outward from the support column 3, causing the rain-proof and protective assembly to move out simultaneously and unfold to form a protective canopy. Its coverage extends to the outside of all support columns 3, creating a complete rain barrier for the multi-layered medicinal herb racks 5 below. Simultaneously, the medicinal herb racks 5 concentrate the herb-bearing area in the center, effectively reducing the risk of rainwater drifting in along the columns. During the drying stage, the guide component drives the rain-proof and protective assembly to fold and retract, retracting it inside the support column 3 to avoid blocking sunlight and ensure efficient drying.

[0029] For example, multiple support columns 3 are detachably connected to the base unit 1 in a matrix array (using bolts). Multi-layered, perforated mesh-like medicinal herb racks 5 allow for detachable, orderly stacking from top to bottom, forming a three-dimensional drying space. This enables rapid assembly and disassembly, significantly reducing space occupancy during equipment storage and greatly improving the convenience and flexibility of transportation, effectively reducing warehousing and transportation costs.

[0030] Please refer to Figure 5 In some embodiments of this application, multiple shaft-connecting sleeves 4 are evenly distributed along the circumferential direction on the edge of the herbal medicine holder 5, with their number corresponding one-to-one with the support columns 3. Each shaft-connecting sleeve 4 has an installation groove 17 inside, and a positioning component is assembled in the installation groove 17; multiple positioning slots 18 are distributed at intervals along the axial direction of the support column 3, and the positioning slots 18 and the positioning components form a positioning fit structure. Taking a four-support column 3 as an example, the four shaft-connecting sleeves 4 on the edge of the herbal medicine holder 5 are coaxially sleeved on the outside of the corresponding support column 3 to achieve a detachable connection. When the height of the herbal medicine holder 5 is adjusted in the assembly area, the shaft-connecting sleeves 4 move synchronously along the axial direction of the support column 3 with the herbal medicine holder 5; when the herbal medicine holder 5 reaches the preset height position, the positioning component inside the shaft-connecting sleeve 4 is exactly aligned with the positioning slot 18 of the corresponding height. Through the embedded fit between the positioning component and the positioning slot 18, the herbal medicine holder 5 is quickly positioned and stably locked.

[0031] Specifically, the positioning assembly includes a first positioning pin 20 and a return spring 19. The return spring 19 is sleeved on the outside of the first positioning pin 20 and is entirely placed within the mounting groove 17 of the shaft sleeve 4. One end of the return spring 19 is securely connected to the inner wall of the mounting groove 17, and the other end is connected to the outer wall of the first positioning pin 20, thereby giving the first positioning pin 20 the ability to engage with the positioning slot 18 of the support column 3 under the action of the return spring 19. To ensure the smoothness and accuracy of the movement of the first positioning pin 20, the first positioning pin 20 and the inner wall of the mounting groove 17 can be a guide fit structure. Under the continuous action of the elastic force of the return spring 19, the first positioning pin 20 is forcefully pushed into the corresponding positioning slot 18, realizing the stable positioning of the shaft sleeve 4, thereby ensuring the reliable fixation of the Chinese herbal medicine bracket 5 in the preset position.

[0032] When the height of the herbal medicine holder 5 needs to be adjusted, the operator only needs to apply a pulling force to the outside of the mounting channel 17 on the first positioning pin 20, so that the first positioning pin 20 can be smoothly disengaged from the current positioning slot 18, thereby releasing the locking state of the shaft sleeve 4. After all the locking of the shaft sleeves 4 on the edge of the herbal medicine holder 5 has been released, the herbal medicine holder 5 can be raised and lowered. When the holder moves to the new preset position, the pulling force applied to the first positioning pin 20 is released, and the return spring 19 drives the first positioning pin 20 to quickly engage with the corresponding positioning slot 18, realizing the positioning of the herbal medicine holder 5 in the new position.

[0033] Please refer to Figure 1 and Figure 6 In some embodiments of this application, the guide member consists of a guide portion 11 and an L-shaped connecting portion 12. The guide portion 11 forms a guiding fit with the inner wall of the support column 3, ensuring the stability of the guide portion 11's movement within the support column 3. The connecting portion 12 is connected to the foldable rainproof protective assembly. When it rains, the guide portion 11 translates outward along the axis of the support column 3. During this process, the connecting portion 12 simultaneously drives the foldable rainproof protective assembly to move. After the foldable rainproof protective assembly moves outside the support column 3, it unfolds to form a rainproof structure, and the limiting component in the mounting channel 21 of the guide portion 11 automatically aligns with the extension positioning hole 9 on the upper part of the support column 3.

[0034] During the drying process, the foldable rainproof and protective component folds up, and the guide part 11 moves in the opposite direction within the support column 3. The guide part 11 drives the connecting part 12 to move, and the guide part 11 moves the folded rainproof and protective component into the support column 3. After the foldable rainproof and protective component is completely retracted into the support column 3, the limiting component automatically engages with the folding positioning hole 10 at the bottom of the support column 3, ensuring that the foldable rainproof and protective component maintains zero displacement during the drying process, thereby providing an unobstructed three-dimensional drying space for the Chinese medicinal materials.

[0035] Specifically, to further enhance the stability and reliability of the limiting component, the limiting pin 23 and the inner wall of the assembly channel 21 adopt a guide-fit structure. When rainfall occurs, the elastic element 22 drives the limiting pin 23 to engage with the extension positioning hole 9 based on its own restoring force, thereby achieving a stable fixation of the guide part 11 and completing the overall positioning of the guide component. At this time, the foldable rainproof protection component has been moved to the outside of the support column 3 and can be quickly unfolded by manual operation, immediately forming a rainproof barrier covering the drying area, effectively blocking rainwater from damaging the Chinese medicinal materials.

[0036] During the drying process, the operator first folds the foldable rainproof and protective assembly, then applies external force to the limiting pin 23, causing it to overcome the elastic force of the elastic element 22 and retract into the assembly channel 21, compressing the elastic element 22 and disengaging it from the limiting restraint of the extension positioning hole 9. After the limit is released, the guide moves downward along the axis of the support column 3, causing the guide part 11 to move synchronously. When the limiting pin 23 reaches the folding positioning hole 10, the elastic element 22 releases its stored elastic potential energy, pushing the limiting pin 23 into the folding positioning hole 10, thus re-establishing a stable mechanical limiting structure. This firmly locks the guide and the foldable rainproof and protective assembly inside the support column 3, completely eliminating the adverse effects of the rainproof assembly on natural light and ventilation during the drying process, providing ideal environmental conditions for the drying of Chinese medicinal materials, and ensuring the drying effect.

[0037] In some embodiments of this application, the foldable rainproof protective assembly adopts a hinged structure design. Specifically, two first folding rods 6 are connected to the L-shaped connecting portion 12 via hinges. During drying operations, the first folding rods 6 can rotate to a state parallel to the connecting portion 12 and be stored within the internal space of the support column 3; in case of rainfall, the first folding rods 6 can quickly unfold to a position perpendicular to the connecting portion 12, providing a supporting foundation for the tensioning of the rainproof covering layer 8.

[0038] Please refer to Figures 1 to 4 The foldable rainproof and protective assembly achieves coordinated expansion and contraction through a hierarchical hinge network: the end of the first folding rod 6 is hinged to the first connecting member 13, the second folding rod 7 is connected to the first connecting member 13 through another hinge point, and the two second folding rods 7 are hinged to the same second connecting member 14, forming a foldable four-bar mechanism. In drying mode, the second folding rod 7 can be rotated in conjunction with the first folding rod 6 to achieve flattened storage of the entire assembly; when the rainproof mechanism is triggered, the first folding rod 6 and the second folding rod 7 unfold together to form a stable rectangular support frame.

[0039] The flexible rainproof covering 8 is made of highly elastic waterproof fabric and is tightly bonded to the inner surface of the folding rods through a hot-press bonding process, forming an integrated protective structure. When the foldable rainproof protective assembly is unfolded, the rectangular frame composed of two first folding rods 6 and two second folding rods 7, together with the rainproof covering 8, forms a complete rainproof barrier. This structure adopts a dual-support fixing strategy. The first support point of the rectangular frame is connected to the connecting part 12 through the first folding rod 6, and the second support point of the rectangular frame is positioned and locked to the top of the diagonal support column 3 through the second connector 14, ensuring that the structure can maintain its stability in windy and rainy environments. Thanks to the elastic deformation characteristics of the flexible material, the rainproof covering 8 can adaptively compress during folding and storage, and is stored inside the support column 3 together with the folding rods. This not only ensures the rainproof function of the rainproof covering 8, but also achieves efficient space utilization with zero obstruction during drying operations, significantly improving environmental adaptability and ease of operation.

[0040] Please refer to Figure 4 In some embodiments of this application, the foldable rainproof and protective component innovatively adopts a dual-pivot positioning and locking mechanism. The second connector 14 is connected to the locking adapter plate 15 through a hinge structure. The surface of the locking adapter plate 15 is provided with positioning through holes, which form a matching system with the positioning lock holes at the top of the preset support column 3.

[0041] When the foldable rainproof and protective assembly unfolds to form a rectangular protective frame, stable load-bearing is achieved based on the principle of dual-point mechanical support: the first support point is connected to the connecting part 12 via the first folding rod 6, providing horizontal constraint; the second support point uses the second connecting piece 14 to form a positioning and locking structure with the top of the diagonal support column 3. During operation, the locking adapter plate 15 can be rotated to fit against the top plane of the diagonal support column 3, so that the positioning through hole and the positioning lock hole coincide. At this time, the second positioning pin 16 is inserted into the positioning through hole and the positioning lock hole in sequence, effectively restricting the spatial freedom of the second connecting piece 14. This structural design greatly improves the rectangular frame's resistance to overturning and deformation in wind and rain environments, ensuring the stability of the rainproof barrier.

[0042] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
