[0016] This application discloses a sieving device for grinding traditional Chinese medicine. (Refer to...) Figure 1 , Figure 3 The system includes a sieving box 1, within which a rotating plate 3 is rotatably connected via a rotating shaft 27, allowing the rotating plate 3 to rotate relative to the sieving box 1 about the rotating shaft 27. A support bearing 28 is detachably fixed to the outer wall of the sieving box 1 via bolts. One end of the rotating shaft 27 passes through the sieving box 1 and is interference-fitted into the support bearing 28, connecting the rotating shaft 27 to the sieving box 1. The support bearing 28 also ensures that the rotating shaft 27 does not interfere with the rotation of the rotating plate 3 relative to the sieving box 1. A crank handle 29 is welded or inserted through the rotating shaft 27 and support bearing 28, allowing for convenient control of the rotation of the rotating shaft 27, and consequently, the rotation of the rotating plate 3. Corresponding positioning holes 30 are provided on the sieving box 1 and the rotating plate 3. A positioning rod 31 is inserted into each positioning hole 30, limiting the rotation of the rotating plate 3 and preventing it from rotating automatically, which would affect the sieving of the ground medicinal herbs.

[0017] Reference Figure 1 , Figure 3A support assembly is connected to the rotating plate 3, and the support assembly is rotatably connected to the sieve cylinder 6. This allows the sieve cylinder 6 to be connected to the rotating plate 3 via the support assembly, which also drives the sieve cylinder 6 to rotate for sieving. Connecting blocks 7 are welded to or detachably fixed to both ends of the sieve cylinder 6 via bolts, ensuring that both ends of the sieve cylinder 6 are connected to connecting blocks 7. The support assembly is connected to the sieve cylinder 6 via the connecting blocks 7, supporting the connecting blocks 7 and driving them to rotate. This supports the sieve cylinder 6 and enables its rotation, thus sieving the ground Chinese medicine entering the sieve cylinder 6. The rotation of the sieve cylinder 6 improves sieving efficiency and prevents clogging of the sieve screen. The support assembly includes a support base 4, a connecting seat 4.1, support wheels 5, a drive wheel 12, and a drive motor 11. One end of the support base 4 is detachably fixed to the rotating plate 3 by bolts, allowing the support base 4 to rotate with the rotating plate 3. This, in turn, allows the entire support assembly to rotate with the rotating plate 3, enabling the sieve cylinder 6 to reach a certain moving angle. This facilitates the sieving of the Chinese herbal powder within the sieve cylinder 6 and allows for the convenient discharge of larger volumes of Chinese herbal powder from the sieve cylinder 6. The connecting seat 4.1 is arc-shaped, and its middle section is welded to or detachably fixed to the support base 4 by bolts, connecting the connecting seat 4.1 and the support base 4. Both ends of the connecting seat 4.1 are connected to the support wheels 5 via connecting shafts 4.2, allowing the support wheels 5 to rotate relative to the connecting seat 4.1 about the connecting shafts 4.2. A connecting groove 8 is provided on the connecting block 7, and a support wheel 5 is disposed in the connecting groove 8. The support wheel 5 supports the connecting block 7 in the connecting groove 8, and in turn, the support wheels 5 at both ends support both ends of the screening cylinder 6. The support wheel 5 does not affect the rotation of the connecting block 7 and the screening cylinder 6 relative to the connecting seat 4.1. In addition, the connecting groove 8 restricts the support wheel 5 to prevent the connecting block 7 from detaching from the support wheel 5, thus affecting the support provided by the support wheel 5 to the connecting block 7 and the screening cylinder 6. The drive wheel 12 is detachably fixed to the output shaft of the drive motor 11 by bolts, so that the drive wheel 12 is connected to the output shaft of the drive motor 11, and the drive motor 11 is energized and its output shaft drives the rotating wheel to rotate. The drive wheel 12 is set in the connecting groove 8 and abuts against the connecting block 7, so that the drive wheel 12 rotates to drive the connecting block 7 to rotate, and then drives the sieving cylinder 6 to rotate, thereby realizing the sieving of Chinese medicine powder. At the same time, the connecting groove 8 is used to limit the drive wheel 12 to prevent the drive wheel 12 from separating from the connecting block 7 and affecting the drive wheel 12 to drive the connecting block 7 to rotate.An upper plate 9 is vertically and detachably fixed to the rotating plate 3 above the sieving cylinder 6 via bolts. The upper plate 9 is located between the connecting blocks at both ends of the sieving cylinder 6, connecting the upper plate 9 to the rotating plate 3 and sealing the top of the sieving cylinder 6 to prevent the Chinese medicine powder from scattering randomly inside the sieving box. The drive motor 11 is detachably and fixed to the upper plate 9 via a fixing seat 10 via bolts, connecting the drive motor 11 to the upper plate 9. A side plate 26 parallel to the rotating plate 3 is vertically and detachably fixed to the upper plate 9 via bolts, connecting the side plate 26 to the upper plate 9. This forms a three-sided enclosed space through the upper plate 9, side plate 26, and rotating plate 3, allowing the Chinese medicine powder sieved by the sieving cylinder 6 to fall downwards sufficiently. One end of the support seat 4 is detachably and fixedly connected to the side plate 26 via bolts, connecting the side plate to the rotating plate 3 through the support seat 4, making the three-sided enclosed space formed by the upper plate 9, side plate 26, and rotating plate 3 more stable.

[0018] Reference Figure 1 , Figure 2 , Figure 3 One end of the sieving cylinder 6 is connected to a feed hose 16, and the other end is connected to a discharge hopper 19. This allows the ground Chinese medicine powder to be fed into the sieving cylinder 6 through the feed hose 16, and the large volume of powder to be discharged from the sieving cylinder 6 through the discharge hopper 19. The feed hose 16 is connected to a feed hopper 18, allowing the ground Chinese medicine powder to be added to the sieving box 1 through the feed hopper 18 and then fed into the feed hose 16. Both the feed hopper 18 and the discharge hopper 19 are funnel-shaped, facilitating the addition of ground Chinese medicine powder to the sieving box 1 and the discharge of large volumes of powder from the sieving cylinder 6. A sealing plate 2 is detachably fixed to the upper end of the sieving box 1 with bolts, connecting the sealing plate 2 to the sieving box 1 and sealing the opening of the sieving box 1. The detachable connection also allows for easy access to the internal components for maintenance. The sealing plate 2 has a feed inlet 17, and the feed hopper 18 and feed hose 16 are connected to the feed inlet 17 to facilitate the transfer of Chinese medicine powder entering the feed hopper 18 into the feed hose 16.

[0019] Reference Figure 1 , Figure 2A baffle 13 is detachably and fixedly connected to the inner end face of the connecting block 7 near the feed hose 16 by bolts. This baffle 13 blocks the end of the sieve cylinder 6 away from the discharge hopper 19, preventing the Chinese medicine powder entering the sieve cylinder 6 from leaking out from the end of the sieve cylinder 6 and affecting the sieving efficiency of the Chinese medicine powder. A connecting hole 14 is provided on the baffle 13, and a connector 15 is provided in the connecting hole 14. The feed hose 16 is connected to the connector 15, so that the feed hose 16 and the baffle 13 are connected together through the connector 15. This allows the Chinese medicine powder to be conveyed into the sieve cylinder 6 through the feed hose 16, without affecting the rotation of the connecting block 7 and the sieve cylinder 6 relative to the connecting hose. The outer end face of the connector 15 is provided with a snap-fit ​​groove, and the inner end face of the connecting hole 14 is set in the snap-fit ​​groove, so that the connector 15 and the baffle 13 are limited by the snap-fit ​​groove, preventing the connector 15 from automatically disengaging from the connecting hole 14, while allowing the connector 15 to rotate relative to the baffle 13.

[0020] Reference Figure 1 , Figure 3 The larger diameter end of the discharge hopper 19 is detachably fixed to the end of the sieve cylinder 6 via bolts, connected to the connecting block 7. This seals the end of the sieve cylinder 6 away from the feed hose 16, preventing the herbal powder entering the sieve cylinder 6 from leaking out. Several arc-shaped guide plates 20 are welded to or detachably fixed to the inner end face of the discharge hopper 19 via bolts. These guide plates confine the herbal powder within the sieve cylinder 6. When the sieve cylinder 6 rotates clockwise to sieve the herbal powder, the arc-shaped guide plates 20 confine the powder, preventing leakage from the discharge hopper 19. When the sieve cylinder 6 rotates counterclockwise, the arc-shaped guide plates 20 facilitate the discharge of large volumes of herbal powder from the sieve cylinder 6. A limiting cover 21 is connected to the end face of the sieve box 1 near the discharge hopper 19, which allows the sieve cylinder 6's discharge hopper 19 to be limited by the limiting cover 21, thus limiting the rotation angle of the sieve cylinder 6 with the rotating plate 3. The lower end of the limiting cover 21 is connected to and communicates with a discharge channel 22 extending outside the sieve box 1, which allows large volumes of traditional Chinese medicine powder discharged from the sieve cylinder 6 to be discharged from the sieve box 1 through the discharge channel 22. A receiving hopper 23 is connected to the sieve box 1 below the sieve cylinder 6 via a support rod 24, which allows the traditional Chinese medicine powder sieved out by the sieve cylinder 6 to be received by the receiving hopper 23. The lower end of the receiving hopper 23 is connected to an extension discharge pipe 25 inside the sieve box 1, allowing the traditional Chinese medicine powder falling into the receiving hopper 23 to be discharged from the sieve box 1 through the discharge pipe 25.

[0021] In use, first, the positioning rod 31 is inserted into the positioning hole 30 to position the rotating plate 3. Then, the ground Chinese medicine powder is poured into the feed hopper 18. The Chinese medicine powder is conveyed to the sieve cylinder 6 along the feed hose 16. Next, the drive motor 11 is powered on and the output shaft of the drive motor 11 drives the drive wheel 12 to rotate. The drive wheel 12 drives the connecting block 7 and the sieve cylinder 6 to rotate. After sieving is completed, the positioning rod 31 is pulled out from the positioning hole 30, and the crank 29 is turned so that the rotating plate 3 drives the sieve cylinder 6 to tilt. At the same time, the drive motor 11 is rotated in the opposite direction to discharge the large volume of Chinese medicine powder in the sieve cylinder 6. This completes the sieving of the ground Chinese medicine powder.

[0022] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
