Description

Technical Field

[0001] This utility model relates to the technical field of medicinal material drying devices, specifically a Chinese medicinal material drying device. Background Technology

[0002] Drying medicinal herbs is a crucial step in the pre-processing of traditional Chinese medicine (TCM) herbs. If the moisture content of TCM herbs is controlled within a certain limit under specific conditions during storage, they are less prone to spoilage. Therefore, harvested TCM herbs must be dried to a safe moisture limit promptly to ensure their quality. In the TCM herb cultivation industry, after harvesting, herbs are generally cleaned, dried, and then sold. The drying process should be carried out in a way that does not affect the medicinal properties of the herbs.

[0003] In the prior art, such as the Chinese herbal medicine drying device disclosed in announcement number CN211823643U, this technical solution discloses a Chinese herbal medicine drying device, including a circular rotating component, multiple herbal medicine carrying frames, and a driving device for driving the rotating component to rotate; the driving device is driven and connected to the center of the rotating component; the multiple herbal medicine carrying frames are evenly arranged in a ring on the rotating component, and each herbal medicine carrying frame can rotate along its own axis. During the rotation of the rotating component, the herbal medicine carrying frames always remain in a horizontal state. The Chinese herbal medicine drying device of this utility model is equipped with multiple herbal medicine carrying frames, each of which rotates around the rotating component. While making full use of sunlight for drying, it also allows the herbs to have full contact with air, using flowing air to accelerate the drying of the herbs. Furthermore, the herbal medicine carrying frames are always in a state of uniform rotation, which can ensure that the herbs inside each frame are dried evenly, thus ensuring the quality of the dried herbs and further shortening the drying time.

[0004] However, when using the existing technology for drying Chinese medicinal materials, the top of the medicinal materials on the carrying frame can only be dried. Since sunlight cannot reach the bottom of the medicinal materials, the medicinal materials cannot be heated evenly, resulting in low drying efficiency.

[0005] To address the aforementioned issues, this application proposes a device for drying Chinese medicinal herbs. Utility Model Content

[0006] This utility model aims to provide a Chinese herbal medicine drying device, which mainly solves the problem that existing Chinese herbal medicine drying devices can only dry the top of the herbs on the support frame. Since sunlight cannot reach the bottom of the herbs, the herbs cannot be heated evenly, resulting in low drying efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A device for drying Chinese medicinal herbs includes a support frame, a rotating shaft, and a turntable. Multiple support frames are rotatably connected to the turntable, and a fixed frame is connected above each support frame. Screens are fixedly connected to the inner walls of both the support frames and the fixed frames. Insert blocks are fixedly connected to both sides of the bottom of the fixed frame. The top of the support frame has slots that match the insert blocks. The insert blocks are provided with limiting components for fixing them inside the slots. Connecting shafts are fixedly connected to both sides of the support frame. The connecting shafts pass through the turntable and are rotatably connected to the turntable. A drive component for rotating the support frames is provided at the end of the connecting shaft away from the support frame.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When using this device, the cleaned Chinese medicinal materials are evenly spread on the screen inside each carrier frame. Then, the insert block at the bottom of the fixed frame is inserted into the slot on the carrier frame, and the insert block is fixed in the slot by the limiting component. In this way, the Chinese medicinal materials are fixed between the carrier frame and the fixed frame. Then, the motor is started, and the rotating shaft drives the turntable to rotate. At the same time, the rotating disc rotates, and the carrier frame rotates by the drive component, so that the sunlight shines evenly on each carrier frame and dries the medicinal materials evenly.

[0011] 2. Beneficial effects: During the operation of this device, by fixing the Chinese medicinal materials between the carrier frame and the fixed frame, the Chinese medicinal materials can be effectively prevented from falling. While the turntable drives the carrier frame to rotate, the drive component can make the carrier frame rotate at the same time. Sunlight can be evenly irradiated on the top and bottom of the Chinese medicinal materials through the screens on the inner walls of the carrier frame and the fixed frame, which can make the Chinese medicinal materials heat more evenly, thereby effectively improving the drying efficiency of the Chinese medicinal materials.

[0012] Preferably, the limiting component includes a sliding cavity opened on one side of the insert block, a wedge block slidably connected inside the sliding cavity, one side of the wedge block extending out of the sliding cavity, and a spring fixedly connected to the other side. The other end of the spring is fixedly connected to the inner wall of the sliding cavity. The inner wall of the slot is provided with a through groove that matches the wedge block. The cleaned Chinese medicinal materials are evenly spread on the sieve inside each carrier frame. Then, the insert block at the bottom of the fixed frame is inserted into the slot on the carrier frame. The inner wall of the slot presses the inclined surface of the wedge block on the insert block, causing it to slide automatically into the sliding cavity. When the insert block is fully inserted into the sliding cavity, the wedge block will pop out under the action of the spring and engage with the through groove, thus fixing the fixed frame on the carrier frame. The device can then operate normally. After the Chinese medicinal materials are dried, the wedge blocks on both sides of the carrier frame are pressed simultaneously to make them slide into the sliding cavity. When the wedge blocks disengage from the through groove, the fixed frame can be disassembled, making it convenient for people to take out the Chinese medicinal materials on the carrier frame.

[0013] Preferably, the drive assembly includes a gear fixedly connected to the end of the connecting shaft away from the support frame, fixed sleeves fixedly connected to the opposite sides of the two support frames, a rotating shaft passing through the fixed sleeve and rotatably connected to the fixed sleeve, multiple connecting rods fixedly connected to the outer wall of the fixed sleeve, and a gear ring fixedly connected to the side of the connecting rod away from the fixed sleeve. The gear ring meshes with the gear. During the operation of the device, when the turntable drives the support frame to make a circular motion, the support frame will drive the gear to make a circular motion through the connecting shaft. Through the meshing connection between the gear and the gear ring, the support frame can rotate, so that sunlight can evenly irradiate the top and bottom of the Chinese medicinal materials, thereby effectively improving the drying efficiency of the Chinese medicinal materials.

[0014] Preferably, sliders are fixedly connected to both sides of the wedge block, and the inner wall of the sliding cavity is provided with a groove that matches the slider. When the wedge block slides inside the sliding cavity, the sliders on both sides of the wedge block and the grooves on the inner wall of the sliding cavity can play a good role in limiting and guiding the wedge block. This not only makes the wedge block more stable when sliding inside the sliding cavity, but also effectively prevents the wedge block from leaving the inside of the sliding cavity.

[0015] Preferably, one side of the wedge block extending out of the sliding cavity is rotatably connected to multiple balls, and the balls are distributed in a linear array at equal intervals on the wedge block. During the insertion of the insert into the slot, one side of the wedge block will abut against the inner wall of the slot under the action of the spring. The multiple balls on one side of the wedge block can effectively reduce the friction between the wedge block and the inner wall of the slot, which makes the assembly and disassembly of the fixing frame more convenient.

[0016] Preferably, there are multiple springs inside the slide cavity, and the springs are distributed in a linear array at equal intervals inside the slide cavity. By setting the number of springs inside the slide cavity to multiple, the multiple springs can exert a greater thrust on the wedge block. This allows the wedge block to better fix the insert block when it engages with the through slot under the action of multiple springs, thereby making the connection between the fixed frame and the load-bearing frame more secure.

[0017] Preferably, all corners at the top of the inner wall of the slot are chamfered. By chamfering all corners at the top of the inner wall of the slot, it is easier to insert the plug into the slot, thus making the installation of the fixing frame easier. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5A Chinese herbal medicine drying device includes a support frame 1, a rotating shaft 2, and a turntable 3. Multiple support frames 4 are rotatably connected to the turntable 3, and a fixed frame 5 is connected above each support frame 4. Screens 6 are fixedly connected to the inner walls of both the support frames 4 and the fixed frames 5. In use, the washed Chinese herbal medicine is first evenly spread on the screens 6 inside each support frame 4. Inserts 7 are fixedly connected to both sides of the bottom of the fixed frame 5. The top of the support frame 4 has slots 8 that match the inserts 7. The corners at the top of the inner wall of the slots 8 are chamfered to facilitate insertion of the inserts 7 into the slots 8. Each insert 7 has a limiting component for fixing it inside the slot 8. Then, the inserts 7 at the bottom of the fixed frame 5 are inserted into the slots 8 on the support frame 4, and the limiting components secure the inserts. Block 7 is fixed inside slot 8, thus fixing the Chinese medicinal materials between the carrier frame 4 and the fixed frame 5. Then, starting the motor will cause the rotating shaft 2 to rotate the turntable 3. The turntable 3 can drive the carrier frame 4 to perform circular motion. Both sides of the carrier frame 4 are fixedly connected to the connecting shaft 13, which passes through the turntable 3 and is rotatably connected to the turntable 3. The end of the connecting shaft 13 away from the carrier frame 4 is provided with a drive component for rotating the carrier frame 4. While the turntable 3 drives the carrier frame 4 to perform circular motion, the drive component can make the carrier frame 4 rotate simultaneously. Sunlight can evenly irradiate the top and bottom of the Chinese medicinal materials through the screen 6 on the inner wall of the carrier frame 4 and the fixed frame 5, which can make the Chinese medicinal materials heat more evenly and thus effectively improve the drying efficiency of the Chinese medicinal materials.

[0026] like Figure 4 and Figure 5As shown, the limiting assembly includes a sliding cavity 9 opened on one side of the insert block 7. A wedge block 10 is slidably connected inside the sliding cavity 9. Slider blocks 19 are fixedly connected to both sides of the wedge block 10. The inner wall of the sliding cavity 9 has a groove 20 that matches the slider 19. One side of the wedge block 10 extends out of the sliding cavity 9, and multiple springs 11 are fixedly connected to the other side. The springs 11 are distributed in a linear array at equal intervals inside the sliding cavity 9. The other end of the springs 11 is fixedly connected to the inner wall of the sliding cavity 9. Multiple ball bearings 18 are rotatably connected to the side of the wedge block 10 extending out of the sliding cavity 9. The ball bearings 18 are distributed in a linear array at equal intervals on the wedge block 10. The inner wall of the slot 8 has a through groove 12 that matches the wedge block 10. The Chinese medicinal herbs are evenly spread on the sieve 6 inside each carrying frame 4. Then, the insert 7 at the bottom of the fixed frame 5 is inserted into the slot 8 on the carrying frame 4. The inner wall of the slot 8 presses the inclined surface of the wedge block 10 on the insert 7, causing it to slide automatically into the sliding cavity 9. When the insert 7 is fully inserted into the sliding cavity 9, the wedge block 10 will pop out under the action of the spring 11 and engage with the through groove 12, thus fixing the fixed frame 5 on the carrying frame 4. The device can then operate normally. After the Chinese medicinal herbs are dried, the wedge blocks 10 on both sides of the carrying frame 4 are pressed at the same time to make them slide into the sliding cavity 9. When the wedge blocks 10 are disengaged from the through groove 12, the fixed frame 5 can be removed, making it convenient for people to take out the Chinese medicinal herbs on the carrying frame 4.

[0027] like Figure 1 As shown, the drive assembly includes a gear 14 fixedly connected to the end of the connecting shaft 13 away from the bearing frame 4. Fixed sleeves 15 are fixedly connected to opposite sides of the two support frames 1. A rotating shaft 2 passes through the fixed sleeve 15 and is rotatably connected to the fixed sleeve 15. Multiple connecting rods 16 are fixedly connected to the outer wall of the fixed sleeve 15. A gear ring 17 is fixedly connected to the side of the connecting rod 16 away from the fixed sleeve 15. The gear ring 17 meshes with the gear 14. During operation, when the turntable 3 drives the bearing frame 4 to rotate, the bearing frame 4 will drive the gear 14 to rotate via the connecting shaft 13. Through the meshing connection between the gear 14 and the gear ring 17, the bearing frame 4 can rotate, allowing sunlight to evenly illuminate the top and bottom of the medicinal materials, thereby effectively improving the drying efficiency of the medicinal materials.

[0028] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0029] When using this device, the cleaned Chinese medicinal herbs are evenly spread on the sieve 6 inside each support frame 4. Then, the insert 7 at the bottom of the fixing frame 5 is inserted into the slot 8 on the support frame 4. The inner wall of the slot 8 presses against the inclined surface of the wedge-shaped block 10 on the insert 7, causing it to slide automatically into the sliding cavity 9. When the insert 7 is fully inserted into the sliding cavity 9, the wedge-shaped block 10 will pop out under the action of the spring 11 and engage with the through groove 12. The fixing frame 5 can be fixed on the support frame 4. At this time, the Chinese medicinal materials are fixed between the support frame 4 and the fixing frame 5, which can effectively prevent the Chinese medicinal materials from falling. When the motor is started, the rotating shaft 2 will drive the turntable 3 to rotate. The turntable 3 can drive the support frame 4 to make circular motion. When the turntable 3 drives the support frame 4 to make circular motion, the support frame 4 will drive the gear 14 to make circular motion through the connecting shaft 13. Through the meshing connection between the gear 14 and the gear ring 17, the support frame 4 can rotate. This allows the sunlight to shine evenly on the top and bottom of the Chinese medicinal materials, thereby effectively improving the drying efficiency of the Chinese medicinal materials.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
