[0002] In the production of Chinese herbal medicine slices, crushing and grading are two crucial steps. Traditional Chinese herbal medicine crushing equipment often suffers from uneven crushing, low grading efficiency, and dusty working environments. These issues not only affect the production quality of Chinese herbal medicine slices, but also cause serious pollution to the working environment and pose a threat to the health of operators.
[0003] Specifically, traditional pulverizing equipment typically utilizes a single pulverizing mechanism, which cannot ensure uniform pulverization of the medicinal slices. This results in uneven particle sizes, impacting subsequent grading. Furthermore, the grading process often relies on manual screening or simple screening equipment, resulting in low grading efficiency and precision, making it difficult to meet the high-efficiency and high-precision requirements of modern Chinese medicine slice production.
[0004] Furthermore, the dust and fine particles generated during traditional crushing and grading processes easily become airborne, polluting the work environment and potentially damaging the respiratory system of operators. Therefore, developing a device capable of dust-free crushing and efficient grading of TCM slices is crucial for improving the production quality of TCM slices, enhancing the work environment, and safeguarding the health of operators. To address this issue, we propose a dust-free crushing and grading device for TCM slices. Utility Model Content

[0028] As a preferred embodiment of this embodiment, the recycling box 3 is divided into several recycling bins by a plurality of lower partitions 31, and a second door 30 is hingedly mounted on the outer wall of the recycling box 3, located on the outside of each recycling box 3. The recycling box 3 is divided into multiple recycling bins by the plurality of lower partitions 31, and each recycling bin is equipped with a second door 30, so that the graded medicinal pieces can be collected separately, facilitating subsequent processing and use, thereby improving the practicality and convenience of the device.
[0029] As a preferred embodiment of this embodiment, two first doors 10 are symmetrically hingedly mounted on the top of the crushing box 1. Each first door 10 is mounted on the top of a handle 11. An annular support plate 13 is fixedly mounted near the top of the crushing box 1 to support the first doors 10. This facilitates the operator to open and close the doors for feeding or cleaning, thereby improving the ease of operation of the device.
[0030] As a preferred embodiment of this embodiment, two meshing gears 14 are symmetrically mounted on the outer wall of the crushing box 1. The two gears 14 are coaxially fixed to the two crushing rollers 12. A motor mounting plate 15 is fixedly mounted on the outer wall of the crushing box 1.

The cooperation between the two meshing gears 14 and the crushing motor 16 achieves synchronous rotation of the two crushing rollers 12, ensuring uniform crushing of the medicinal slices and improving crushing efficiency and quality.
[0031] As a preferred embodiment of the present invention, a feed port 24 is provided on the top of the screening box 2 and is connected to the crushing box 1. The feed port 24 is provided at the upper end of the top of the crushing box 1. This facilitates the operator to put the medicinal pieces into the crushing box 1 for crushing, while ensuring that the crushed medicinal pieces can smoothly enter the screening box 2 for classification.
[0032] As a preferred embodiment of the present invention, the outer ring wall of the multi-stage filter 20 is in contact with the inner wall of the crushing box 1. The outer ring wall of the multi-stage filter 20 is in contact with the inner wall of the crushing box 1, ensuring that all the crushed pieces can fall on the multi-stage filter 20 for classification, thereby avoiding omission and waste of pieces.
[0033] As a preferred embodiment of the present invention, the bottom of the recycling box 3 is horizontal, and each of the four corners of the bottom is fixedly connected to a support leg 4. This makes the overall structure of the device stable, easy to place and use, and also improves the safety and reliability of the device.
[0034] The dust-free crushing and grading device for Chinese herbal medicine slices of the utility model is used:
[0035] First, the operator places the Chinese herbal medicine pieces to be crushed into the crushing box 1 through the two first doors 10 at the top. Once the materials are added, the first door 10 is closed and the crushing motor 16 is started. The crushing motor 16, via a coaxially fixed gear 14, drives the two meshing gears 14 to rotate synchronously, which in turn drives the two crushing rollers 12 to rotate symmetrically within the crushing box 1, uniformly crushing the Chinese herbal medicine pieces.
[0036] The crushed Chinese herbal medicine pieces pass through the feed port 24 at the top of the screening box 2 and fall onto the multi-stage filter screen 20 near the top of the screening box 2. Because the multi-stage filter screen 20 is tilted and the filter holes in each section gradually increase from top to bottom, the pieces of medicine with different particle sizes are classified on the multi-stage filter screen 20. Finer pieces of medicine pass through the smaller filter holes and fall into the recovery box 3 below, while larger pieces of medicine remain on the filter screen and continue to slide downward until they pass through the filter holes that match their particle size and fall into the recovery box 3.
[0037] During the screening process, the activation of the four vibrating motors 23 promotes the effective separation of the medicinal slices on the filter screen, improving grading efficiency. Furthermore, the upper partition 21 fixed between two adjacent sections at the bottom of the multi-stage filter screen 20, and the lower partition 31 inside the recovery bin 3, facing the upper partition 21, in conjunction with the corrugated plate 22 installed between the upper and lower partitions 21, further improve the accuracy and efficiency of the medicinal slice grading, preventing medicinal slices of different grades from mixing during the recovery process.
[0038] The graded pieces fall into the recovery box 3 and are collected separately in multiple recovery bins separated by several lower partitions 31. Each recovery bin is hingedly mounted with a second door 30 on the outside, which makes it easy for the operator to open the door and take out the graded pieces for subsequent processing and use.
[0039] Finally, when the device is finished using, the operator can open the first door 10 to clean the inside of the crushing box 1; at the same time, the operator can also open the second door 30 of the recovery box 3 to thoroughly clean the medicinal pieces in the recovery bin to keep the device clean and tidy.
[0040] In summary, the dust-free crushing and grading device for Chinese herbal medicine slices of the utility model realizes the effective crushing and grading of Chinese herbal medicine slices through the combination of the inclined screening box 2 and the crushing box 1, as well as the ingenious design of components such as the multi-stage filter 20, the vibration motor 23, and the recovery box 3, thereby improving the grading efficiency and accuracy, while also maintaining the cleanliness of the working environment and the practicality and convenience of the device.
