Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine decoction piece production technology, specifically relating to an adjustable medicinal material fermentation box. Background Technology

[0002] Medicinal herb fermentation is a processing technique that utilizes microorganisms to biotransform traditional Chinese medicinal materials under specific environmental conditions. Its purpose is to alter the structure or content of certain chemical components in the herbs through microbial metabolism, thereby enhancing efficacy, reducing toxicity, or generating new pharmacological activities. Currently, many modern medicinal herb fermentation equipment possess basic control functions such as temperature, humidity, and ventilation, enabling them to simulate and regulate the micro-ecological environment required for fermentation to a certain extent, improving fermentation efficiency and product quality consistency. However, in practical applications, traditionally designed fermentation chambers still suffer from the following problems:

[0003] Firstly, taking the common tray-type fermentation box as an example, its interior typically employs a fixed or semi-fixed tray structure, arranging multiple fermentation trays vertically and equidistantly to achieve efficient space utilization and increase single-batch processing capacity. However, the connection between the trays and the box body in this structure is relatively simple, mostly using pre-reserved slots or snap-fit ​​installations, lacking stability and adjustment flexibility. It is difficult to flexibly adjust the spacing between layers or the overall layout according to the volume, shape, and fermentation cycle characteristics of different medicinal materials, limiting the equipment's versatility and adaptability, and affecting production efficiency and process adaptability.

[0004] Secondly, the support structure inside traditional fermentation chambers is quite complex, creating many hard-to-clean areas. These areas are difficult to reach and clean, and over time, residues can accumulate, leading to the growth of bacteria and increasing the risk of cross-contamination, which in turn affects the quality and safety of subsequent batches of products. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an adjustable medicinal herb fermentation box to solve the problems existing in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is an adjustable medicinal material fermentation box, including a box body, an installation rail provided on the inner side wall of the box body, the length direction of the installation rail being vertically arranged, a support strip provided on the installation rail, and a fermentation tray arranged between the support strips located on the same horizontal plane; a clamp is provided between the support strips and the installation rail; the support strips are detachably mounted on the installation rail under the action of the clamp; by controlling the number and position of the support strips on the installation rail, the position of the fermentation trays in the fermentation box can be flexibly changed, so that the fermentation box can adjust the overall layout of the fermentation trays in the fermentation box according to the properties of the medicinal materials to be fermented.

[0007] Preferably, the mounting rail has a groove; the clamp can switch between a retracted state and a fixed state; the clamp includes a fixed plate connected to the support bar, and a locking block and a control block are slidably disposed on the fixed plate. The locking block is located on both sides of the control block, and both the locking block and the control block have trigger surfaces. The locking block and the control block slide and fit together through the trigger surfaces; when the clamp is in the retracted state, the distance between the locking blocks is less than the groove opening size, so that the locking block and the control block can smoothly enter the groove before operation; when the clamp switches from the retracted state to the fixed state, the control block moves along a set direction and drives the locking block to move synchronously under the action of the trigger surfaces, so that the locking block can be displaced along the length direction of the support bar on the fixed plate; as the distance between the locking blocks gradually increases, the locking block eventually fits tightly against and acts on the two side walls of the groove, thereby fixing the clamp.

[0008] Furthermore, the fixture includes an operating block, and the operating block and the control block are rotatably connected. The operating block and the control block are located on opposite sides of the fixed plate. The connection point between the operating block and the control block is the rotation point, the contact surface between the operating block and the fixed plate is the guide surface, and the area on the guide surface that contacts the fixed plate is the guide area. As the operating block rotates, the guide area changes continuously, and the distance from the rotation point to the guide area also changes accordingly. During the rotation of the operating block, when the distance from the rotation point to the guide area gradually increases, that is, when the rotation point gradually moves away from the fixed plate, the control block can be moved along a set direction.

[0009] Furthermore, a lifting area is formed between the support strips located on the same horizontal plane, and the lifting area is used to place the fermentation tray; when the clamp is in a fixed state, the operating block will not be located directly above the lifting area formed by the support strips on the horizontal plane, thereby avoiding interference with the placement or removal of the fermentation tray.

[0010] Furthermore, the housing has a sealed door, and the mounting rails are arranged on the side walls on both sides of the sealed door. The mounting rails are divided into a near rail close to the sealed door and a far rail away from the sealed door. The clamps are divided into a near clamp acting on the near rail and a far clamp acting on the far rail. The near clamp and the support bar are fixedly or slidably connected, and the operating block of the far clamp and the support bar are fixedly connected. When the far clamp and the far rail are connected, the support bar drives the operating block to rotate, which in turn drives the control block to move in a set direction, thereby realizing the control of the far clamp's action through the support bar. This solves the problems of large housing depth and inconvenient clamp operation.

[0011] Furthermore, the fixing plate of the remote clamp has limiting structures at both ends; under the action of the limiting structures, the remote clamp in the retracted state can only move along the length direction of the remote rail after being placed on the remote rail, ensuring that the remote clamp can maintain its position when the support bar drives the operating block to rotate.

[0012] Furthermore, in the remote clamp, the distance from the rotation point to the guide area is closest when the length direction of the support bar is perpendicular to the contact end face of the fixed plate; the distance from the rotation point to the guide area is farthest when the length direction of the support bar is parallel to the contact end face of the fixed plate; when the remote clamp switches from the retracted state to the fixed state, the relative rotation between the support bar and the remote clamp causes the distance from the rotation point to the guide area to gradually increase, causing the rotation point to gradually move away from the fixed plate, thereby driving the control block to move along the set direction.

[0013] Furthermore, the support bar includes a swing member, one end of which is connected to the operating block of the distal clamp, and the other end of which is connected to the proximal clamp; the end of the swing member connected to the distal clamp is smoothly curved to ensure smooth movement of the swing member; the swing of the swing member drives the operating block to rotate.

[0014] Furthermore, the support bar includes a fixing member, one end of which is fixedly mounted on the far clamp, and the length direction of the fixing member is parallel to the contact end face of the fixing plate; the fixing member is located on the far rail away from the near rail, and the swing member is located on the far rail close to the near rail; when the swing member adjusts the far clamp to a fixed state, the length direction of the fixing member and the length direction of the swing member are parallel and located on the same horizontal line.

[0015] Furthermore, the contact surfaces between the clamp and the mounting rail are treated with anti-slip material to prevent the clamp from moving when it is in a fixed state; the periphery of the locking block is made of elastic material so that after the locking block contacts the mounting rail, the compression and rebound characteristics of the elastic material prevent the locking block from loosening with the mounting rail.

[0016] The main technical effects of this invention are reflected in the following aspects:

[0017] The clamp can switch between a "retracted state" and a "fixed state," enabling quick installation and removal of the support strip on the mounting rail. The clamp, through an internally designed linkage structure of locking blocks, control blocks, and operating blocks, causes the control blocks to slide when the operating block rotates, further expanding or contracting the locking blocks. When the spacing between the locking blocks is smaller than the groove opening size, it is in the "retracted state," facilitating insertion into the rail; when the locking blocks expand and press tightly against the side walls of the groove, it enters the "fixed state." This mechanical linkage design allows for clamp locking and releasing without external tools. It significantly improves the efficiency of support strip installation and removal, enhances the ease of operation and maintainability of the equipment, and is suitable for applications requiring frequent changes in fermentation processes.

[0018] The operating block and control block are connected by a rotation point and have a guide surface that contacts the fixed plate to form a guide area. As the operating block rotates, the contact area (guide area) between the guide surface and the fixed plate changes, causing the distance from the rotation point to the guide area to dynamically adjust. This drives the control block to move in a set direction, causing the clamping block to expand or contract. This achieves an efficient conversion from rotary motion to linear motion, improves the response speed and stability of the clamping action, simplifies the operation process, and reduces the need for manual intervention.

[0019] The design distinguishes between near and far clamps, enabling differentiated operation of clamps in different spatial locations. The mounting rails are divided into "near rails" (closer to the sealed door) and "far rails" (farr from the sealed door), with corresponding "near clamps" and "far clamps." Near clamps are located in easily accessible areas and are directly operated manually; far clamps, located deep within the enclosure, employ a linkage structure, using a support bar to rotate the operating block, achieving automatic locking or releasing. This solves the problem of inconvenient operation of traditional clamps in deep cavity areas, improving the overall spatial adaptability of the equipment and the human-machine interface experience.

[0027] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0028] This invention provides an adjustable fermentation box for medicinal materials, aiming to solve the problems of fixed structure, non-adjustable layout, and inconvenient cleaning of traditional fermentation equipment. It is mainly suitable for processing steps in the production of Chinese medicinal materials that require a high level of fermentation environment, such as the production of prepared slices of Chinese medicinal herbs, fungal medicinal materials, and fermented processed products. However, it is not limited to this application and can also be used in other similar or identical production processes.

[0029] Furthermore, as is common knowledge in this industry, the sealing structure of enclosure 1, the temperature and humidity control module, and the track installation method mentioned above are all common knowledge; therefore, their principles and structures will not be elaborated upon further.

[0030] Example 1

[0031] See Figure 1 This embodiment discloses an adjustable medicinal herb fermentation box, including a box body 1. The box body 1 serves as the main structure of the entire device, providing a sealed environment to control fermentation conditions such as temperature and humidity.

[0032] See Figure 3By optimizing the structure of the mounting rail 2, support strips 3, and clamps 4, the placement of the fermentation trays can be flexibly adjusted. The mounting rail 2 is installed on the inner wall of the housing 1, serving to support and guide the position adjustment of the support strips 3. The mounting rail 2 is vertically oriented, and support strips 3 are mounted on it. Fermentation trays are positioned between the support strips 3 on the same horizontal plane, supporting the medicinal herbs to be fermented. Clamps 4 are installed between the support strips 3 and the mounting rail 2, enabling quick installation, disassembly, and positioning of the support strips 3. The support strips 3 are detachably mounted on the mounting rail 2 under the action of the clamps 4. Through the synergistic effect of the above structures, users can freely adjust the height spacing and quantity distribution of each fermentation tray according to the volume, shape, and fermentation cycle requirements of different medicinal herbs, significantly improving the equipment's versatility and process adaptability. By controlling the number and position of the support strips 3 on the installed rail 2, the position of the fermentation trays inside the fermentation box can be flexibly changed, so that the fermentation box can adjust the overall layout of the fermentation trays inside the fermentation box according to the properties of the medicinal materials to be fermented.

[0033] Traditional fermentation tanks typically employ fixed or slot-type support strips 3, lacking flexibility. In this embodiment, the support strips 3 are detachably connected to the mounting rail 2 via clamps 4, and the layout of the fermentation trays can be dynamically adjusted by controlling the number and position of the support strips 3 on the mounting rail 2. The support strips 3 can be installed at any height on the mounting rail 2; multiple layers can be stacked or partially left empty to meet different process requirements; disassembly and assembly are simple, facilitating maintenance and cleaning.

[0034] See Figure 3 , Figure 5 , Figure 6 Furthermore, the clamp 4 can be switched between a retracted state and a fixed state by rotating the operating block 45, thereby completing the quick installation or removal of the support strip 3. The mounting rail 2 has a groove 21; the clamp 4 can switch between a retracted state and a fixed state; the clamp 4 includes a fixing plate 41 connected to the support strip 3, and a locking block 42 and a control block 43 are slidably disposed on the fixing plate 41; there are two locking blocks 42, located on both sides of the control block 43; both the locking block 42 and the control block 43 have a trigger surface 44, and the locking block 42 and the control block 43 slide against each other through the trigger surface 44; the trigger surface 44 allows the displacement of the control block 43 to be effectively transmitted to the locking block 42, driving it to move synchronously; this ensures that the locking block 42 is fully fitted with the wall of the groove 21 when the clamp 4 is in the fixed state, enhancing the clamping force and stability.

[0035] When the clamp 4 is in the retracted state, this state is applicable to the installation or disassembly stage of the clamp 4, ensuring that the clamp 4 can be freely inserted into or detached from the mounting rail 2; the spacing between the locking blocks 42 is smaller than the slot size of the groove 21, so that before operation, the locking blocks 42 and the control block 43 can smoothly enter the groove 21; before the clamp 4 is locked, the user inserts the clamp 4 into the groove 21 of the mounting rail 2.

[0036] When the clamp 4 switches from the retracted state to the fixed state, after the clamp 4 is inserted into the groove 21, the user changes its posture by rotating the operating block 45, thereby driving the entire clamp 4 into the fixed state. This state achieves a stable connection between the clamp 4 and the mounting rail 2, ensuring that the support strip 3 will not loosen or fall off due to vibration or load. The control block 43 moves along a set direction and, under the action of the trigger surface 44, drives the locking block 42 to move synchronously, allowing the locking block 42 to be displaced along the length direction of the support strip 3 on the fixing plate 41. As the distance between the locking blocks 42 gradually increases, the locking blocks 42 eventually press against and act on the two side walls of the groove 21, thus fixing the clamp 4. The clamp 4 drives the control block 43 to slide by rotating the operating block 45, and further drives the locking block 42 to expand, forming a linkage system that transforms rotational motion into linear motion. This design can lock the clamp 4 without external tools, making it easy to operate and compact in structure.

[0037] See Figure 5 , Figure 6 Furthermore, by cleverly designing the rotation path of the operating block 45 and the change mechanism of the guide surface 47, toolless switching of the state of the fixture 4 from "retracted" to "fixed" is achieved. The clamp 4 includes an operating block 45, which is rotatably connected to the control block 43. The operating block 45 and the control block 43 are located on opposite sides of the fixed plate 41. The connection point between the operating block 45 and the control block 43 is the rotation point 46. The contact surface between the operating block 45 and the fixed plate 41 is the guide surface 47, and the area on the guide surface 47 that contacts the fixed plate 41 is the guide area. As the operating block 45 rotates, the guide area changes continuously, and the distance from the rotation point 46 to the guide area also changes accordingly. During the rotation of the operating block 45, when the distance from the rotation point 46 to the guide area gradually increases, that is, when the rotation point 46 gradually moves away from the fixed plate 41, the control block 43 can be moved along a set direction. Since there is a connection between the operating block 45 and the control block 43 at the rotation point 46, this change in distance will force the control block 43 to move along a set direction (usually horizontal).

[0038] See Figure 2 , Figure 3 , Figure 5 Furthermore, the spatial layout between the clamp 4 and the support strips 3 is optimized to ensure that when the clamp 4 is in a fixed state, its key components (such as the operating block 45) will not affect the normal placement and removal of the fermentation tray, thereby improving the ease of operation and efficiency of the equipment. A support area 31 is formed between the support strips 3 located on the same horizontal plane. The support area 31 is used to place the fermentation tray. The purpose of the support area 31 is to provide a stable, flat, and unobstructed support platform for the fermentation tray, ensuring that the medicinal materials are heated evenly and well-ventilated during fermentation, and facilitating manual or automated loading and unloading operations. To ensure that the fermentation tray can be smoothly placed or removed, any component of the clamp 4 (especially the operating block 45) must be avoided from obstructing or interfering with the support area 31. When the clamp 4 is in a fixed state, the operating block 45 will not be located directly above the support area 31 formed by the support strips 3 on the same horizontal plane, thereby avoiding interference with the placement or removal of the fermentation tray.

[0039] Specifically, to avoid the inconvenience caused by the presence of the operating block 45 in placing and moving the fermentation tray, the operating block 45 can be placed below the support strip 3. Although this method can effectively avoid the operating area of ​​the fermentation tray and avoid interference with the placement and removal of the fermentation tray, thereby improving loading and unloading efficiency and space utilization, this layout also brings new problems: when the clamp 4 is located deep inside the fermentation tank, the operating block 45 is in a low or concealed position, making it difficult for the staff to directly contact the operating block 45 and complete the state switching of the clamp 4 when installing or removing the support strip 3. This makes the fixing or releasing operation of the clamp 4 difficult and affects the overall ease of use.

[0040] Furthermore, specifically addressing the issue that while placing the operating block 45 below the support strip 3 avoids interference with the fermentation tray operation, it also presents installation difficulties, a solution based on "near clamp - far clamp" zoned control is proposed. This achieves efficient and convenient operation of the clamp 4 inside the deep cavity box 1. The box 1 has a sealing door 11, and the mounting rails 2 are located on the side walls on both sides of the sealing door 11. The mounting rails 2 are divided into a near rail 22 closer to the sealing door 11 and a far rail 23 farther from the sealing door 11. The purpose of setting "near rail 22" and "far rail 23" is to differentiate the operation method according to the different positions of the clamp 4. The clamp 4 is divided into a near clamp that acts on the near rail 22 and a far clamp that acts on the far rail 23. The near clamp and the support bar 3 are fixedly or slidably connected. The operating block 45 of the far clamp and the support bar 3 are fixedly connected. When the far clamp and the far rail 23 are connected, the support bar 3 drives the operating block 45 to rotate, which in turn drives the control block 43 to move in a set direction. This allows the support bar 3 to control the action of the far clamp, solving the problems of the large depth of the box 1 and the inconvenience of operating the clamp 4.

[0041] The movement of the support bar 3 automatically triggers the switching of the remote clamp's action, allowing for the fixing or release of the remote clamp without manual intervention. By implementing a "near clamp-far clamp" partitioned design for the clamp 4 and introducing an innovative mechanism for the support bar 3 to control the remote clamp's action, the technical challenges of inconvenient operation of the clamp 4, particularly the difficulty in operating the deep-cavity clamp 4, are effectively solved. This solution not only retains the clamp 4's ability to avoid interference with the fermentation tray's operating area but also significantly improves the equipment's adaptability and operational efficiency in complex spatial layouts. It has promising prospects for engineering application and is suitable for modern Chinese medicinal herb fermentation equipment applications that require both high space utilization and ease of operation.

[0042] See Figure 3 Furthermore, in actual use, when the clamp 4 is in the retracted state (i.e., the locking block 42 is not expanded and the clamp 4 is not locked) and placed on the mounting rail 2, if the clamp 4 itself has a degree of freedom in the lateral or tilting direction, the following problems may occur: The clamp 4 may slide or deviate on the rail; when the support bar 3 drives the operating block 45 to rotate, the remote clamp cannot accurately respond to the linkage action; the locking block 42 cannot expand smoothly, causing the clamp 4 to be unable to enter the fixed state; installation failure or repeated adjustments are required, affecting operating efficiency and equipment stability. Therefore, in order to ensure that the clamp 4 transitions smoothly and reliably from the "retracted state" to the "fixed state", the following improvements have been made: The fixing plate 41 of the remote clamp has limiting structures 48 at both ends, and the limiting structures 48 form a matching relationship with the mounting rail 2, restricting the degree of freedom of movement of the remote clamp on the mounting rail 2. Under the action of the limiting structure 48, the remote clamp, in its retracted state, can only move along the length of the remote rail 23 after being placed on the remote rail 23, ensuring that the remote clamp remains in an inconvenient position when the support bar 3 drives the operating block 45 to rotate. During this process, because the remote clamp is fixed in position by the limiting structure 48, the locking block 42 can accurately fit against the side wall of the groove 21, completing the locking action of the clamp 4; without the limiting structure 48, the clamp 4 may shift due to uneven force, causing the locking block 42 to fail to expand normally or to become misaligned.

[0043] Furthermore, the movement trajectory of the operating block 45 is adjusted due to the change in angle between the remote clamp and the contact end face of the fixed plate 41 along the length direction of the support bar 3, and how it drives the control block 43 to move through the "change in distance from the rotation point 46 to the guide area," thereby completing the switching process of the clamp 4 from the "retracted state" to the "fixed state." In the remote clamp, the distance from the rotation point 46 to the guide area is closest when the length direction of the support bar 3 is perpendicular to the contact end face of the fixed plate 41; the distance from the rotation point 46 to the guide area is farthest when the length direction of the support bar 3 is parallel to the contact end face of the fixed plate 41; when the remote clamp switches from the retracted state to the fixed state, the relative rotation between the support bar 3 and the remote clamp causes the distance from the rotation point 46 to the guide area to gradually increase, causing the rotation point 46 to gradually move away from the fixed plate 41, thereby driving the control block 43 to move along the set direction.

[0044] See Figure 4 Furthermore, the support bar 3 includes a swing element 32. One end of the swing element 32 is connected to the operating block 45 of the far clamp, and the other end of the swing element 32 is connected to the near clamp. The end of the swing element 32 connected to the far clamp is smoothly curved to ensure smooth movement of the swing element 32. The swing of the swing element 32 drives the operating block 45 to rotate. The swing element 32 is the core actuator for realizing the linkage control of the far clamp. It transmits the operating force from the near clamp to the far clamp, enabling it to complete the state switching of the clamp 4.

[0045] During actual equipment installation, due to the needs of the internal space layout, ventilation path, or maintenance passage of the fermentation tank, the far rail 23 is sometimes set at a position far from the depth of the tank body 1, that is, closer to the sealing door 11. The support strip 3 includes a fixing member 33, one end of which is fixedly mounted on the far clamp. The length direction of the fixing member 33 is parallel to the contact end face of the fixing plate 41. The fixing member 33 is located on the far rail 23 on the side away from the near rail 22, and the swing member 32 is located on the far rail 23 on the side closer to the near rail 22. When the swing member 32 adjusts the far clamp to the fixed state, the length direction of the fixing member 33 and the length direction of the swing member 32 are parallel and located on the same horizontal line.

[0046] Furthermore, the contact surfaces between the clamp 4 and the mounting rail 2 are treated with anti-slip material to prevent the clamp 4 from moving when it is in a fixed state; the periphery of the locking block 42 is made of elastic material so that after the locking block 42 and the mounting rail 2 come into contact, the compression and rebound characteristics of the elastic material will prevent the locking block 42 from becoming loose from the mounting rail 2.

[0047] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

The adjustable medicinal herb fermentation box as described in claim 1 or 2, characterized in that: In the aforementioned clamp, the distance from the rotation point to the guide area is shortest when the length direction of the support bar is perpendicular to the contact end face of the fixing plate; the distance from the rotation point to the guide area is farthest when the length direction of the support bar is parallel to the contact end face of the fixing plate. When the remote clamp switches from the retracted state to the fixed state, the relative rotation between the support bar and the remote clamp gradually increases the distance from the rotation point to the guide area, causing the rotation point to gradually move away from the fixed plate, thereby driving the control block to move along the set direction.

4. The adjustable medicinal herb fermentation box as described in claim 3, characterized in that: The contact surfaces between the clamp and the mounting rail are treated with anti-slip material to prevent the clamp from moving when it is in a fixed state. The outer periphery of the locking block is made of elastic material, so that after the locking block comes into contact with the mounting rail, the compression and rebound characteristics of the elastic material will prevent the locking block from becoming loose with the mounting rail.
