Description

Technical Field

[0001] This utility model relates to the technical field of equipment for processing Chinese medicinal materials, and in particular to a drying rack for preparing Polygonatum and wolfberry tea. Background Technology

[0002] Polygonatum and wolfberry tea is a health-promoting beverage made primarily from Polygonatum and wolfberry. It boasts various health benefits, including nourishing yin and kidneys, nourishing the liver and improving eyesight, and enhancing immunity, and has gained popularity among consumers in recent years. In the processing of Polygonatum and wolfberry tea, Polygonatum, as one of the core ingredients, has a significant impact on the quality of the final product due to its pre-processing techniques. Sun-drying, a crucial step in the initial processing of Polygonatum, not only relates to the preservation of its effective components but also directly affects its storage stability and subsequent processing performance. Therefore, during the processing of Polygonatum, specialized drying racks are typically used to achieve natural drying operations that are well-ventilated, rainproof, dust-proof, and easy to manage.

[0003] The utility model patent CN 220911839 U discloses a Solomon's seal drying rack, including a support frame and multiple drying frames. The support frame is equipped with a shielding component, a driving component, and a connecting component. The driving component moves the shielding panels, allowing for rapid coverage of the drying area in case of sudden weather events such as rain, effectively preventing the Solomon's seal from getting wet and causing quality degradation or loss. Simultaneously, the connecting component enables synchronous control of multiple shielding components, significantly improving operational efficiency and convenience. However, shortcomings still exist in practical use:

[0004] To improve mobility, the drying rack is equipped with casters at the bottom. While this facilitates manual relocation to different drying locations, it also results in poor stability when stationary. Especially on uneven ground or in strong winds, the rack is prone to shifting or even tipping over, threatening not only the equipment itself but also potentially causing spillage and contamination of the Solomon's seal, severely impacting production and product quality. Furthermore, the casters reduce the rack's overall rigidity when stationary, increasing the risk of structural swaying from even minor external forces, further affecting the stability and safety of the Solomon's seal drying process.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a drying rack for Polygonatum and Lycium barbarum tea preparation to solve this problem. This drying rack should, while maintaining its original efficient shading function, optimize the bottom support structure to improve the stability and wind resistance of the equipment when placed, thereby effectively avoiding the risk of tipping over due to the moving wheels; at the same time, it should possess good adaptability and operational safety, significantly improving the reliability and efficiency of the Polygonatum drying process, better meeting the development needs of modern processing and green production of traditional Chinese medicinal materials, and providing strong support for the high-quality development of the Polygonatum and Lycium barbarum tea industry.

[0006] The purpose of this utility model is to provide a Solomon's seal drying rack for preparing Solomon's seal and wolfberry tea. This solves the problem that in the prior art, drying racks with casters installed at the bottom to improve mobility, while facilitating manual transfer to different drying locations, suffer from poor stability when placed.

[0007] To achieve the above objectives, this utility model provides a Polygonatum drying rack for preparing Polygonatum and wolfberry tea, including a base and a drying rack set on top of the base. The drying rack has several drying frames connected inside, and the drying rack has casters installed at the four corners of the bottom.

[0008] Several drying racks are arranged linearly along the vertical direction of the drying rack. Inclined plates are fixedly connected to both sides of the base. Two limiting grooves adapted to the moving wheels are opened on the top of the two inclined plates and the base. Mounting plates are fixedly connected to the other two sides of the base. Vertical plates are fixedly connected to the top two sides of each mounting plate. A limiting structure adapted to the side wall of the drying rack is provided on one side of the vertical plate. The limiting structure is connected to the side wall of the vertical plate through a horizontal adjustment structure.

[0009] The limiting structure includes a vertical plate, and a limiting frame is fixedly connected to the top of one side and the bottom of the other side of the vertical plate. The width of the inner wall of the limiting frame is adapted to the width of the drying rack rod.

[0010] Each of the drying racks has two symmetrically arranged cover plates on its top, and two movable plates are arranged on one side of the drying rack. A bidirectional synchronous moving structure that cooperates with the two movable plates is arranged on the top of one side of the drying rack. The bottom of each cover plate is connected to a sliding plate that slides with the top of the drying rack, and one side of the cover plate is connected to the adjacent movable plate.

[0011] The limiting frame has two inclined side plates connected to one side, and the two side plates are symmetrically arranged.

[0012] The bidirectional synchronous moving structure includes a mounting frame connected to the side wall of the drying rack and a bidirectional lead screw rotatably connected inside the mounting frame. A drive motor that cooperates with the bidirectional lead screw is installed on one side of the mounting frame, and both moving plates are threadedly engaged with the bidirectional lead screw.

[0013] The horizontal adjustment structure includes an adjustment screw rotatably connected to one side of the vertical plate. One end of the adjustment screw is threaded through the vertical plate, and a guide rod is provided at the bottom of the adjustment screw. One end of the guide rod is connected to the side wall of the vertical plate, and the other end slides through the vertical plate.

[0014] This utility model discloses a drying rack for preparing Polygonatum and Lycium barbarum tea. Through the combination of a limiting groove and movable wheels, it effectively solves the problems of instability and tipping caused by the movable wheels in existing drying racks. Especially on uneven ground or in strong winds, the limiting groove provides reliable lateral limiting support, preventing the equipment from sliding or tipping over, thus ensuring the safety of the equipment and materials. Secondly, the application of a limiting structure combined with a horizontal adjustment structure allows users to precisely position and reinforce the drying rack according to the actual usage environment, improving the rigidity and anti-interference ability of the equipment in a fixed state, and avoiding damage caused by... Slight external force-induced shaking affects the drying quality of Polygonatum odoratum; secondly, the design of the inclined plate and limiting groove not only enhances the structural strength of the bottom support, but also simplifies the limiting operation process and improves the ease of use of the equipment; finally, the overall structure takes into account both mobility and placement stability, retaining the advantages of traditional drying racks that are easy to move, while making up for their shortcomings in adapting to harsh weather conditions, comprehensively improving the safety, reliability and work efficiency of the Polygonatum odoratum drying process, providing a more scientific and stable solution for the processing of Chinese medicinal materials, and meeting the industrial needs of modern green production and high-quality development.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, a Solomon's seal drying rack for preparing Solomon's seal and wolfberry tea in this embodiment includes a base 1 and a drying rack 3 set on top of the base 1. Several drying frames 2 are connected inside the drying rack 3, and casters 14 are installed at the four corners of the bottom of the drying rack 3.

[0025] Several drying racks 2 are arranged linearly along the vertical direction of the drying rack 3. Inclined plates 6 are fixedly connected to both sides of the base 1. Two limiting grooves 7 adapted to the moving wheels 14 are opened on the top of the two inclined plates 6 and the base 1. Mounting plates 8 are fixedly connected to the other two sides of the base 1. Vertical plates 5 are fixedly connected to the top two sides of each mounting plate 8. A limiting structure adapted to the side wall of the drying rack 3 is provided on one side of the vertical plate 5. The limiting structure is connected to the side wall of the vertical plate 5 through a horizontal adjustment structure.

[0026] First, the drying rack 3 is moved to a suitable drying area using the casters 14 installed at the four corners of the bottom. Then, the limiting structure and horizontal adjustment structure are adjusted according to the ground conditions to stabilize and fix the drying rack 3. During the drying process, several drying frames 2 are arranged in a linear array along the vertical direction of the drying rack 3, which facilitates the layering of Polygonatum odoratum raw materials and achieves good ventilation and uniform light exposure. When the drying rack 3 is in a fixed state, the casters 14 are partially embedded in the limiting grooves 7 by the cooperation of the inclined plates 6 on both sides of the base 1, thereby restricting the lateral movement of the drying rack 3. At the same time, there are upright plates 5 on the mounting plates 8 on the other two sides of the base 1. One side of the upright plate 5 is connected to the limiting structure. The limiting structure can flexibly adjust the contact pressure with the side wall of the drying rack 3 through the horizontal adjustment structure to further enhance the overall stability. The limiting structure can be finely adjusted according to the wind force or the ground inclination to ensure that the drying rack 3 remains stable under various environmental conditions. In addition, the design of the casters 14 still retains the convenience of moving the equipment and meets the actual needs of frequently changing the drying position.

[0027] Example 2

[0028] Please see Figure 1-5As shown in this embodiment, a Solomon's seal drying rack for preparing Solomon's seal and wolfberry tea includes a limiting structure comprising a vertical plate 9. A limiting frame 12 is fixedly connected to the top and bottom of one side of the vertical plate 9. The inner wall width of the limiting frame 12 is adapted to the width of the drying rack 3's rod. Specifically, by including the vertical plate 9 in the limiting structure, and the limiting frame 12 fixedly connected to the top and bottom of one side of the vertical plate 9, with the inner wall width of the limiting frame 12 adapted to the width of the drying rack 3's rod, when fixing the drying rack 3, the vertical plate 9 is brought close to the drying rack 3, causing the limiting frame 12 to engage with the drying rack 3's rod. The workflow involves adjusting the position of the vertical plate 9 and using the limiting frame 12 for fixation, achieving stable support for the drying rack 3 and preventing lateral or longitudinal movement during use, thus improving the stability of the equipment.

[0029] Two inclined side plates 13 are connected to one side of the limiting frame 12. The two side plates 13 are symmetrically arranged. Specifically, the two inclined side plates 13 connected to one side of the limiting frame 12 and the two side plates 13 are symmetrically arranged. When the limiting frame 12 clamps the rod of the drying rack 3, the side plates 13 provide additional support. In the working process, when the vertical plate 9 approaches the drying rack 3, the side plates 13 contact the drying rack 3, providing a more solid fixing effect. This enhances the clamping force of the limiting frame 12 on the drying rack 3, prevents the drying rack 3 from loosening or shifting due to external forces, and further improves the stability and safety of the equipment.

[0030] The horizontal adjustment structure includes an adjusting screw 11 rotatably connected to one side of the vertical plate 9. One end of the adjusting screw 11 is threaded through the vertical plate 5, and a guide rod 10 is provided at the bottom of the adjusting screw 11. One end of the guide rod 10 is connected to the side wall of the vertical plate 9, and the other end slides through the vertical plate 5. Specifically, by including the adjusting screw 11 rotatably connected to one side of the vertical plate 9, one end of the adjusting screw 11 is threaded through the vertical plate 5, and a guide rod 10 is provided at the bottom of the adjusting screw 11. One end of the guide rod 10 is connected to the side wall of the vertical plate 9, and the other end slides through the vertical plate 5, when fine-tuning the position of the vertical plate 9, the adjusting screw 11 is rotated to push or pull back the vertical plate 9. At the same time, the guide rod 10 ensures the directionality and stability of the movement of the vertical plate 9. The working process is to achieve fine-tuning of the vertical plate 9 by manually rotating the adjusting screw 11, which achieves precise adjustment of the contact pressure between the limiting structure and the drying rack 3, ensuring that the drying rack 3 can maintain the best stability in various environments, and enhancing the overall reliability and adaptability of the equipment.

[0031] Example 3

[0032] Please see Figure 1-5As shown in this embodiment, a drying rack for preparing Polygonatum and Lycium barbarum tea has two symmetrically arranged cover plates 15 on the top of each drying frame 2. Two movable plates 4 are arranged on one side of the drying rack 3. A bidirectional synchronous moving structure is provided on the top of one side of the drying rack 3 to cooperate with the two movable plates 4. A sliding plate 16 is connected to the bottom of each cover plate 15 and slides with the top of the drying frame 2. One side of the cover plate 15 is connected to an adjacent movable plate 4. Specifically, each drying frame 2 has two symmetrically arranged cover plates 15 on the top, and two movable plates 4 are arranged on one side of the drying rack 3. A bidirectional synchronous moving structure is provided on the top of one side of the drying rack 3 to cooperate with the two movable plates 4. The bidirectional synchronous moving structure of the plates 4 has a bottom of each cover plate 15 connected to a sliding plate 16 that slides with the top of the drying frame 2. One side of the cover plate 15 is connected to the adjacent moving plate 4. When it is necessary to cover the drying frame 2, the drive motor 19 is started, and the two moving plates 4 are moved synchronously through the bidirectional lead screw 18, so that the cover plate 15 slides along the sliding plate 16 to cover the drying frame 2. The working process is to control the rotation of the bidirectional lead screw 18 by the drive motor 19, so as to realize the automatic opening and closing of the cover plate 15, achieve the purpose of quickly responding to sudden weather changes, protecting the Solomon's seal from rain, and improving the convenience of operation and production efficiency.

[0033] The bidirectional synchronous moving structure includes a mounting frame 17 connected to the side wall of the drying rack 3 and a bidirectional lead screw 18 rotatably connected inside the mounting frame 17. A drive motor 19 cooperating with the bidirectional lead screw 18 is installed on one side of the mounting frame 17. Both moving plates 4 are threadedly engaged with the bidirectional lead screw 18. Specifically, by setting up the bidirectional synchronous moving structure, which includes a mounting frame 17 connected to the side wall of the drying rack 3 and a bidirectional lead screw 18 rotatably connected inside the mounting frame 17, a drive motor 19 cooperating with the bidirectional lead screw 18 is installed on one side of the mounting frame 17, and both moving plates 4 are threadedly engaged with the bidirectional lead screw 18, after the drive motor 19 is started, the bidirectional lead screw 18 rotates, driving the two moving plates 4 to move synchronously inward or outward, thereby controlling the opening and closing of the cover plate 15. The working process is to precisely control the rotation direction and speed of the bidirectional lead screw 18 through the drive motor 19, achieving precise positioning and rapid response of the cover plate 15, achieving the effect of effectively protecting the Polygonatum material from the influence of the external environment, and enhancing the ease of operation and automation level of the equipment.

[0034] In the Polygonatum drying rack for preparing Polygonatum and Lycium barbarum tea provided by this utility model, the complete working process is as follows: First, the drying rack 3 is flexibly moved to a suitable drying site by means of the movable wheels 14 installed at the four corners of the bottom. After selecting the position, the operator adjusts the limiting structure according to the flatness of the ground and the wind conditions. Specifically, the movable wheels 14 are partially embedded in the limiting grooves 7 opened at the top of the base 1 by means of the inclined plates 6 on both sides of the base 1, thereby achieving lateral limiting and preventing the drying rack 3 from sliding or tipping over. At the same time, the mounting plates 8 on the other two sides of the base 1 are provided with upright plates 5, one side of which is connected to the limiting structure. The limiting structure consists of a vertical plate 9, a limiting frame 12, and an inclined side plate 13. The limiting structure is connected to the upright plate 5 by a horizontal adjustment structure, which includes an adjusting screw 11 and a guide rod 10. The adjusting screw 11 can push or pull back the vertical plate 9, making it fit tightly against the side wall of the drying rack 3, while the guide rod 10 ensures the directionality and stability of the vertical plate 9's movement; the limiting frame 12 locks the rod of the drying rack 3, and the side plate 13 provides additional support, thereby enhancing the clamping stability; in addition, several drying frames 2 are arranged in a linear array along the vertical direction inside the drying rack 3, and each drying frame 2 has two cover plates 15 on its top. The bottom of the cover plate 15 slides with the drying frame 2 through the sliding plate 16 and is connected to the moving plate 4; a bidirectional synchronous moving structure is provided on one side of the top of the drying rack 3, including a mounting frame 17, a bidirectional lead screw 18 and a drive motor 19. When encountering sudden rainfall, the drive motor 19 is started, driving the bidirectional lead screw 18 to rotate, thereby driving the two moving plates 4 to move inward synchronously, causing the cover plates 15 to cover the drying frame 2, achieving rapid shading and protection.

[0035] This structural design brings significant benefits. First, the cooperation between the limiting groove 7 and the moving wheel 14 effectively solves the problem of instability and easy tipping caused by the existing drying racks due to the moving wheel setting. Especially when the ground is uneven or in strong winds, the limiting groove 7 can provide reliable lateral limiting support to prevent the equipment from sliding or tipping over, ensuring the safety of the equipment and materials. Second, the application of the limiting structure combined with the horizontal adjustment structure allows users to accurately position and reinforce the drying rack 3 according to the actual use environment, improving the rigidity and anti-interference ability of the equipment in the fixed state, and avoiding the impact of slight external force on the drying quality of Polygonatum. Third, the design of the limiting frame 12 and the side plate 13 enhances the... The clamping force ensures that the drying rack 3 remains stable even in complex environments. Furthermore, the cover plate 15 slides in conjunction with the drying frame 2 via the sliding plate 16 and is controlled by a bidirectional synchronous movement structure, achieving automated opening and closing. This improves the response speed to sudden weather changes and effectively protects the Polygonatum from rain contamination or quality loss. Finally, the overall structure balances mobility and placement stability, retaining the advantages of traditional drying racks in terms of ease of movement while overcoming their shortcomings in adapting to harsh weather conditions. This comprehensively enhances the safety, reliability, and efficiency of the Polygonatum drying process, providing a more scientific and stable solution for the processing of Chinese medicinal materials, and meeting the industrial needs of modern green production and high-quality development.
