[0002] Traditional Chinese medicine (TCM) decoction pieces refer to medicinal materials that have undergone standardized processing under the guidance of TCM theory and are ready for direct use in TCM clinical prescriptions or pharmaceutical preparations. Impurities in decoction pieces include mud, sand, pebbles, metal shavings, and insect eggs. These impurities not only affect medication safety but may also trigger allergies or mechanical damage.

[0003] In the production process of traditional Chinese medicine decoction pieces, screening and dust removal are the core steps to ensure the quality of the finished product. Currently, mainstream equipment usually uses stainless steel woven mesh, which separates the decoction pieces from impurities through mechanical vibration or rotation. When the size of the impurities is close to the size of the sieve holes, hard impurities are easily stuck in the sieve, causing the sieve to fail. Utility Model Content

[0004] To address the problem that hard debris can easily become stuck in the screen when the size of the debris is close to the size of the screen opening, leading to screen failure, this utility model proposes a multi-stage sorting dust removal and screening device for Chinese herbal medicine pieces to overcome the aforementioned technical problems existing in the relevant technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a multi-stage sorting and dust removal screening device for Chinese herbal medicine slices, including a support 1. The outer surface of the support 1 is provided with a first screening component 2 and an adjusting component 3. The first screening component 2 is provided with a scraping component 4 inside, and the support 1 is provided with a second screening component 5 inside. Both the first screening component 2 and the second screening component 5 are used for dust removal screening of Chinese herbal medicine slices. The adjusting component 3 is used to adjust the angle of the first screening component 2, and the scraping component 4 is used to clean the first screening component 2.

[0030] The first screening component 2 is rotated on the outer surface of the support 1, and the first screening component 2 is limited and fixed by the adjusting component 3. The angle of the first screening component 2 can be changed. After the Chinese herbal medicine slices are poured into the first screening component 2, the larger impurities in the Chinese herbal medicine slices are blocked by the first screening component 2 and slide down along the first screening component 2, realizing the first screening of the Chinese herbal medicine slices. If some impurities are stuck in the first screening component 2, the scraping component 4 is driven to move along the first screening component 2. During the movement, the scraping component 4 pushes the impurities stuck in the first screening component 2 to move and can scrape the impurities out of the first screening component 2. The screened Chinese herbal medicine slices fall into the second screening component 5. The second screening component 5 is started to perform dust removal treatment. The second screening component 5 blows out the dust in the Chinese herbal medicine slices, realizing the second screening of the Chinese herbal medicine slices.

[0031] This utility model connects the first screening component 2 and the slag scraping component 4. The slag scraping component 4 is located inside the first screening component 2. When the first screening component 2 is severely blocked, the slag scraping component 4 is driven to move along the first screening component 2. During the movement, the slag scraping component 4 comes into contact with the debris stuck in the first screening component 2 and pushes the debris to move, scraping the debris out of the first screening component 2.

[0032] In one embodiment, the first screening component 2 includes a rotating frame 201, which is rotatably connected to the support 1. A spring 202 is fixedly installed on the top of the rotating frame 201, and a screening hopper 203 is fixedly connected to the top of the spring 202. A first screen 204 is fixedly installed inside the screening hopper 203, and a vibration motor 205 is fixedly installed on the outer surface of the screening hopper 203. A hopper 206 is rotatably connected to the top of the screening hopper 203.

[0033] The Chinese herbal medicine slices are poured into the hopper 206 and enter the screening hopper 203 from the hopper 206. The vibration motor 205 is started, which drives the screening hopper 203 and the first screen 204 to vibrate. During the vibration, the screening hopper 203 compresses the spring 202, which can push the screening hopper 203 to reset. After passing through the first screen 204, the Chinese herbal medicine slices fall below. Larger impurities in the Chinese herbal medicine slices are blocked by the first screen 204 and slide to the outside of the screening hopper 203.

[0034] In one embodiment, the adjustment component 3 includes an arc plate 301, which is fixedly connected to the rotating frame 201. The outer surface of the arc plate 301 is provided with a positioning hole 302, and a positioning bolt 303 is threadedly connected inside the positioning hole 302. The positioning bolt 303 passes through the arc plate 301 and is threadedly connected to the bracket 1.

[0035] The rotating frame 201 is pushed to rotate on the outer surface of the support 1. The rotating frame 201 drives the arc plate 301 to rotate for angle adjustment. After adjustment, the positioning bolt 303 is threaded through the positioning hole 302 on the outer surface of the arc plate 301 and connected to the support 1 to achieve the limiting and fixing of the rotating frame 201. During use, the angle between the rotating frame 201 and the first screen 204 can be adjusted as needed.

[0036] In one embodiment, the slag scraping assembly 4 includes a guide plate 401, which is fixedly connected to the inside of the screening hopper 203. A sliding plate 402 is slidably connected inside the guide plate 401. A screw 403 is threadedly connected to the outer surface of the sliding plate 402. A support plate 404 is rotatably connected to the outer surface of the screw 403. The support plate 404 is fixedly connected to the screening hopper 203. A wing bolt 405 is threadedly connected to the outer surface of the sliding plate 402. A scraper 406 is rotatably connected to the outer surface of the sliding plate 402. A cross hole 407 is provided on the outer surface of the scraper 406. The wing bolt 405 is inserted into the scraper 406 through the cross hole 407.

[0037] Rotate the wing bolt 405 to separate it from the cross hole 407 of the scraper 406, releasing the limiting fixation between the scraper 406 and the sliding plate 402. The scraper 406 rotates downward and contacts the first screen 204. Then, screw the wing bolt 405 back and insert it into the cross hole 407 on the outer surface of the scraper 406. Rotate the screw 403. The rotation trend of the sliding plate 402 on the outer surface of the screw 403 is blocked by the guide plate 401. At this time, the screw 403 can drive the sliding plate 402 to move the scraper 406 along the first screen 204. The scraper 406 can scrape away the debris stuck in the first screen 204.

[0038] In one embodiment, the second screening component 5 includes a gathering hopper 501, which is fixedly installed inside the support 1. A fan 502 and a second screen 503 are fixedly installed on the outer surface of the gathering hopper 501.

[0039] The Chinese herbal medicine pieces that pass through the first screen 204 fall into the collecting hopper 501. The fan 502 is started, and the fan 502 can blow out the dust in the first screen 204. The second screen 503 on the outer surface of the collecting hopper 501 blocks the Chinese herbal medicine pieces to prevent them from being blown out.

[0040] In one embodiment, for the hopper 206, a fixing bolt 6 is fixedly connected to the outer surface of the hopper 206, a baffle 7 is slidably connected to the outer surface of the fixing bolt 6, and a nut 8 is threadedly connected to the outer surface of the fixing bolt 6.

[0041] Rotate the nut 8 to separate it from the baffle 7, release the limiting fixation of the baffle 7, and push the baffle 7 to slide on the outer surface of the hopper 206, thereby changing the opening size of the hopper 206 to control the feeding speed.

[0042] In one embodiment, for the screening hopper 203 described above, a guide plate 9 is fixedly connected to the outer surface of the screening hopper 203.

[0043] Larger debris slides from the screening hopper 203 onto the outer surface of the guide plate 9 and then slides down the guide plate 9 to the ground.

[0044] Through the above technical solution, 1. By connecting the first screening component 2 and the scraper component 4, the scraper component 4 is located inside the first screening component 2. When the first screening component 2 is severely blocked, the scraper component 4 is driven to move along the first screening component 2. During the movement, the scraper component 4 contacts the debris stuck in the first screening component 2 and pushes the debris to move, scraping the debris out of the first screening component 2; 2. By connecting the rotating frame 201 and the arc plate 301, when the rotating frame 201 drives the arc plate 301 to rotate, the angle between the rotating frame 201 and the support 1 is changed. The screening bucket 203 and the first screen 204 installed on the top of the rotating frame 201 rotate accordingly. After adjusting the angle of the first screen 204, the positioning bolt 303 is installed into the appropriate positioning hole 302, thereby limiting and fixing the rotating frame 201, the arc plate 301 and the support 1, and avoiding unnecessary rotation of the rotating frame 201 and the first screen 204.
