Abstract

This utility model provides an adjustable shelf-type natural air-drying rack for Artemisia argyi, relating to the field of air-drying rack technology. It includes a base plate with a fixed cavity at its top. An adjustment mechanism is installed inside the fixed cavity, and a fixed plate is installed at the top of the fixed cavity. Connecting rods are installed on both sides of a rotating block, and a drying frame is installed at one end of each connecting rod. By utilizing the rotating mechanism inside the fixed plate, the drying frame can be moved through the interaction of its second rotating wheel, second worm gear, and second worm wheel. This allows the upper and lower drying frames to be staggered, creating multi-angle ventilation gaps, improving air convection efficiency, accelerating the evaporation rate of Artemisia argyi, shortening the drying cycle, and ensuring that both the front and back of the leaves and the inside and outside of the stems are fully exposed to air. This improves the uniformity of drying, reduces the risk of localized mold growth, and greatly enhances the practicality of the air-drying rack.

Description

Technical Field

[0001] This utility model relates to the field of air drying rack technology, and in particular to an adjustable shelf-type natural air drying rack for Artemisia argyi. Background Technology

[0002] Artemisia argyi is a tall plant, 150-250 cm tall, with a strong aroma. Its leaves are thick and papery, densely covered with hairs. The middle leaves are pinnately shallowly lobed, while the upper leaves are usually unlobed, elliptical or oblong, reaching up to 7-8 cm in length and 1.5 cm in width. When the leaves are rubbed, they often turn into cotton-like fibers. It is used in medicine and is warm, bitter, pungent, and slightly sweet in nature. Pharmacological analysis shows that its volatile oil has inhibitory effects on various molds, cocci, and bacilli, and also has antiasthmatic and antitussive effects.

[0003] In the processing of Qi Ai (Artemisia argyi), natural air drying is a crucial step in preserving its medicinal components and aroma. While air drying racks are commonly used, existing ones typically have a single, integrated structure, making it difficult to rotate and separate the upper and lower sections. This fixed structure prevents the rack from flexibly adjusting the angle of contact between the Qi Ai and the air / sunlight under different wind and light conditions, resulting in poor air circulation, inconsistent drying speeds across different parts of the Qi Ai, and instances of insufficient or excessive drying in certain areas. This severely impacts the quality of the Qi Ai and reduces the effectiveness of the air drying rack, thus diminishing its practicality. Therefore, this invention proposes an adjustable-layer Qi Ai natural air drying rack to address these problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes an adjustable shelf-type natural air-drying rack for Artemisia argyi, which solves the problem in the prior art where it is inconvenient to rotate and stagger the upper and lower drying racks, resulting in poor natural air-drying effects of Artemisia argyi.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an adjustable shelf-type natural air-drying rack for Artemisia argyi, including a base plate, a fixed cavity installed at the top of the base plate, an adjustment mechanism provided inside the fixed cavity, a fixed plate installed at the top of the fixed cavity, a rotating mechanism provided inside the fixed plate, a rotating block installed at the top of the fixed plate, a fixed cavity also installed at the top of the rotating block, connecting rods installed on both sides of the rotating block, and an air-drying frame installed at one end of the connecting rod;

[0006] The rotating mechanism includes a second rotating wheel, a second worm, and a second worm gear. The second rotating wheel is installed at one end of the fixed plate, and the second worm is installed inside the fixed plate on one side. One end of the second rotating wheel is connected to one end of the second worm, and the second worm gear meshes with one side of the second worm. The top end of the second worm gear is connected to the bottom end of the rotating block.

[0007] A further improvement is made in that: the adjusting mechanism includes a transmission rack, a mounting cavity, a first rotating wheel, a first worm, a first worm wheel, and a transmission gear. The transmission rack is disposed inside the fixed cavity, and its top end extends to the outside of the fixed cavity. The top end of the transmission rack is connected to the bottom end of the fixed plate. A mounting cavity is installed above one side of the fixed cavity, and a first rotating wheel is installed below the mounting cavity. A first worm is installed on one side inside the mounting cavity. One end of the first rotating wheel is connected to one end of the first worm. A first worm wheel meshes with one side of the first worm. A transmission gear is coaxially mounted on the rear end of the first worm wheel. One side of the transmission gear meshes with one side of the transmission rack.

[0008] A further improvement is that a limiting groove is provided on one side of the fixed cavity, and a moving block is provided inside the limiting groove. One end of the moving block is connected to one side of the transmission rack.

[0009] A further improvement is that the cross-section of the limiting groove is larger than the cross-section of the moving block, and the limiting groove and the cross-section form a sliding structure.

[0010] A further improvement is that a fixed telescopic belt is installed above the drying frame, a fixed hook is installed at one end of the fixed telescopic belt, and a fixed ring is installed at one end of the drying frame, with the fixed ring and the fixed hook being mutually compatible.

[0011] A further improvement is that two fixed telescopic belts are provided above the drying frame, and the two fixed telescopic belts are symmetrically distributed about the central axis of the drying frame.

[0012] The beneficial effects of this utility model are as follows: By setting a rotating mechanism inside the fixed plate, the interaction between the second rotating wheel, the second worm gear, and the second worm wheel of the rotating mechanism can drive the drying frame to move, staggering the upper and lower drying frames to form multi-angle ventilation gaps, improving air convection efficiency, accelerating the evaporation rate of Qi Ai (Artemisia argyi), shortening the drying cycle, and ensuring that both the front and back of the Qi Ai leaves and the inside and outside of the stems can fully contact the air, improving the uniformity of Qi Ai drying, reducing the risk of localized mold growth, and thus greatly improving the practicality of the drying rack in use; by setting an adjustment mechanism inside the fixed cavity, the transmission rack, mounting cavity, first rotating wheel, and first... The interaction between the worm gear, the first worm wheel, the transmission gear, and the limiting groove allows for adjustment of the distance between the drying frames, resulting in better drying of the Artemisia argyi. When the outside wind is weak, the distance between the drying frames can be increased to increase the cross-sectional area for air circulation between layers, reduce airflow resistance, and allow natural wind to pass through the gaps in the Artemisia argyi more smoothly, avoiding "airflow congestion" caused by excessive spacing and increasing the air contact of the bottom layer of Artemisia argyi. In case of strong winds, the distance between the drying frames can be reduced, using the shelves to create a "damping effect," slowing down the wind speed and guiding the airflow to be evenly dispersed, preventing strong winds from directly blowing over the bundles of Artemisia argyi, and also preventing the leaves of Artemisia argyi from being damaged by mutual friction due to violent shaking.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1, 2 As shown in Figures 3 and 4, this embodiment proposes an adjustable shelf-type natural air-drying rack for Artemisia argyi, including a base plate 1. A fixed cavity 2 is installed at the top of the base plate 1. An adjustment mechanism is provided inside the fixed cavity 2. A fixed plate 3 is installed at the top of the fixed cavity 2. A rotating mechanism is provided inside the fixed plate 3. A rotating block 4 is installed at the top of the fixed plate 3. A fixed cavity 2 is also installed at the top of the rotating block 4. Connecting rods 5 are installed on both sides of the rotating block 4. An air-drying frame 6 is installed at one end of the connecting rod 5.

[0020] The rotating mechanism includes a second rotating wheel 14, a second worm 15, and a second worm gear 16. The second rotating wheel 14 is mounted on one end of the fixed plate 3, and the second worm 15 is mounted on one side inside the fixed plate 3. One end of the second rotating wheel 14 is connected to one end of the second worm 15, and the second worm gear 16 meshes with one side of the second worm 15. The top end of the second worm gear 16 is connected to the bottom end of the rotating block 4. In use, rotating the second rotating wheel 14 drives the second worm 15 to rotate. Because the second worm 15 and the second worm gear 16 mesh... The worm gears 16 mesh with each other, so the second worm gear 16 drives the rotating block 4 to rotate, and then the connecting rod 5 drives the drying frame 6 to rotate. The drying frame 6 is rotated to an appropriate position and staggered to form a multi-angle ventilation gap, which improves the air convection efficiency, speeds up the evaporation of water from the Artemisia argyi, shortens the drying cycle, and allows the front and back of the Artemisia argyi leaves and the inside and outside of the stems to fully contact the air, improving the uniformity of the drying of Artemisia argyi, reducing the risk of localized mold growth, and thus greatly improving the practicality of the drying rack in use.

[0021] The adjusting mechanism includes a transmission rack 7, a mounting cavity 8, a first rotating wheel 9, a first worm 10, a first worm gear 11, and a transmission gear 12. The transmission rack 7 is disposed inside the fixed cavity 2, with its top end extending to the outside of the fixed cavity 2. The top end of the transmission rack 7 is connected to the bottom end of the fixed plate 3. The mounting cavity 8 is installed above one side of the fixed cavity 2, and the first rotating wheel 9 is installed below the mounting cavity 8. The first worm 10 is installed on one side inside the mounting cavity 8, with one end of the first rotating wheel 9 connected to one end of the first worm 10. The first worm gear 11 meshes with one side of the first worm 10, and the transmission gear 12 is coaxially mounted on the rear end of the first worm gear 11. One side of the transmission gear 12 meshes with one side of the transmission rack 7. In use, rotating the first rotating wheel 9 drives the first worm 10 to rotate. The first worm gears 11 mesh with each other, and the first worm gears 11 are coaxially connected with the transmission gear 12. Therefore, the first worm gears 11 drive the transmission gear 12 to rotate. Then, under the limitation of the limiting groove 13 and the moving block, the transmission gear 12 drives the transmission rack 7 to move, adjusting the drying frame 6 to an appropriate height to allow the artemisia argyi to air dry naturally. When the outside wind is weak, the distance between the drying frames 6 can be increased to increase the cross-sectional area of ​​air circulation between layers, reduce airflow resistance, and allow natural wind to pass through the gaps between the artemisia argyi more smoothly, avoiding "airflow congestion" caused by excessive spacing and increasing the air contact of the bottom layer of artemisia argyi. In case of strong wind, the distance between the drying frames 6 can be reduced to form a "damping effect" by using the shelf to block the wind, slow down the wind speed and guide the airflow to be evenly dispersed, preventing strong wind from directly blowing over the artemisia argyi bindings, and at the same time preventing the artemisia argyi leaves from being damaged by mutual friction due to violent shaking.

[0022] A limiting groove 13 is formed on one side inside the fixed cavity 2. A moving block is provided inside the limiting groove 13. One end of the moving block is connected to one side of the transmission rack 7. The cross-section of the limiting groove 13 is larger than the cross-section of the moving block. The limiting groove 13 and the cross-section form a sliding structure. In use, the mutual cooperation between the limiting groove 13 and the moving block can limit the movement of the transmission rack 7, making the transmission rack 7 more stable when moving.

[0023] A fixed telescopic strap 17 is installed above the drying frame 6. A fixed hook 19 is installed at one end of the fixed telescopic strap 17, and a fixed ring 18 is installed at one end of the drying frame 6. The fixed ring 18 and the fixed hook 19 are mutually compatible. There are two fixed telescopic straps 17 above the drying frame 6. The two fixed telescopic straps 17 are symmetrically distributed about the central axis of the drying frame 6. When in use, the fixed telescopic strap 17 is pulled to hang the fixed hook 19 on the fixed ring 18. The two fixed telescopic straps 17 are used to position the mugwort and prevent strong winds from blowing it over, making the mugwort more stable during drying.

[0024] Working principle: First, the worker moves the drying rack to a suitable position, then places the mugwort on top of the drying frame 6. At this point, the worker pulls the fixed telescopic strap 17, hooking the fixed hook 19 onto the fixed ring 18. The two fixed telescopic straps 17 are used to position the mugwort, preventing it from being blown over by strong winds. Then, the second rotating wheel 14 is rotated, driving the second worm gear 15 to rotate. Since the second worm gear 15 and the second worm wheel 16 are meshed, the second worm wheel 16 drives the rotating block 4 to rotate, which in turn drives the drying frame 6 via the connecting rod 5. Rotate the drying frames 6 to the appropriate positions, stagger the drying frames 6, and then rotate the first rotating wheel 9 to drive the first worm 10 to rotate. Since the first worm 10 and the first worm wheel 11 are meshed with each other, and the first worm wheel 11 is coaxially connected with the transmission gear 12, the first worm wheel 11 drives the transmission gear 12 to rotate. Then, under the limit of the limiting groove 13 and the moving block, the transmission gear 12 drives the transmission rack 7 to move, and adjust the drying frames 6 to the appropriate height to carry out the natural air drying treatment of Artemisia argyi.
