When the second rotary drive mechanism drives the support rod to rotate, it drives the kneading piece to rotate. Due to the sliding fit between the slider and the support rod, under the action of centrifugal force, the kneading piece moves radially away from the support rod, and the two sliders approach each other, compressing the first elastic piece. At this time, the distance between the kneading piece and the inner wall of the screen drum is reduced, and the kneading force is increased; when the support rod stops rotating, due to the reset effect of the first elastic piece, the two sliders move away from each other, and the kneading piece moves towards the support rod. The distance between the kneading piece and the inner wall of the screen drum increases, and the kneading force is reduced. In this way, by controlling the rotation of the support rod gap through the second rotary drive mechanism, different kneading forces can be provided to the Chinese medicinal materials in the screen drum, thereby improving its cleaning effect. To sum up, by adopting the utility model, the surface of the Chinese medicinal materials in the sieve drum is rubbed by the kneading part to make its impurities fall off, and the impurities that fall off are caused to fall from the sieve drum into the outer sleeve through the rotation of the sieve drum, and the dust is discharged through the dust suction port. The cleaning component cleans the inner wall of the outer sleeve as the sieve drum rotates, so that the impurities on the inner wall of the outer sleeve are discharged from the slag discharge port, and the impurities and dust that fall into the outer sleeve are cleaned to prevent the dust and impurities from falling into the sieve drum again, thereby improving the cleaning efficiency of the Chinese medicinal materials.

[0020] An outer sleeve 5 is arranged outside the sieve cylinder 3 and fixed to the frame 1, a gap for accommodating the gear ring 32 is arranged between the outer sleeve 5 and the fixed cylinder 2, and the sieve cylinder 3 arranged in the outer sleeve is a mesh structure. The two ends of the outer sleeve 5 are sealingly connected to the sieve cylinder 3 through bearings, so that the leakage of the herbal medicine or dust and impurities in the sieve cylinder 3 is avoided, and the rotation of the sieve cylinder 3 is ensured. A dust suction port 51 is arranged on the upper side of the outer sleeve 5 for connecting with a dust removal device, dust in the outer sleeve 5 can be sucked out by negative pressure, and a residue discharge port 52 is arranged on the lower side for discharging impurities and soil. An outlet 31 is arranged on the end of the sieve cylinder 3 away from the fixed cylinder 2.

[0021] The outer wall of the screen cylinder 3 is provided with at least one set of cleaning assemblies 6 matched with the inner wall of the outer sleeve 5, which rotates synchronously with the rotation of the screen cylinder 3 driven by the first driving mechanism 4, and the cleaning assemblies 6 clean the inner wall of the outer sleeve 5, so that the impurities and soil adhered to the inner wall of the outer sleeve 5 can be discharged from the residue discharge port 52, avoiding the impurities falling into the outer sleeve 5 from entering the screen cylinder 3 again and polluting the Chinese herbal medicine in the screen cylinder 3. Further, the cleaning assembly 6 comprises a support column 61 provided on the outer wall of the screen cylinder 3, the support column 61 is provided with a mounting groove 62 on the side close to the inner wall of the outer sleeve 5, the mounting groove 62 is provided with a sliding rod 63, the second elastic member 64 is arranged between the sliding rod 63 and the inner wall of the mounting groove 62, and the scraping plate 65 is arranged on the sliding rod 63 and in contact with the inner wall of the outer sleeve 5. At this time, when the screen cylinder 3 rotates, the scraping plate 65 rotates with the screen cylinder 3, and the scraping plate 65 scrapes the impurities on the inner wall of the outer sleeve 5, and when the scraping plate 65 rotates to the residue discharge port 52, the impurities fall into the residue discharge port 52. Due to the arrangement of the second elastic member 64, the scraping plate 65 has a tendency to move towards the inner wall of the outer sleeve 5, thereby being able to be pressed on the inner wall of the outer sleeve 5 without rigid contact with the outer sleeve 5, which can ensure that the impurities are scraped clean and reduce the wear between the scraping plate 65 and the outer sleeve 5.

[0022] The screen cylinder 3 is provided with a support rod 7, the support rod 7 is provided with at least two sliding blocks 71, the first elastic member 72 is arranged between the two sliding blocks 71, the two sliding blocks 71 are respectively hinged to a connecting rod 73, and the other end of the two connecting rods 73 is hinged to the rubbing member 74. Further, the rubbing member 74 comprises a rubbing plate 741, and the rubbing plate 741 is provided with a flexible pad 742. Through the arrangement of the flexible pad 742, the rigid contact between the rubbing plate 741 and the Chinese herbal medicine is reduced, the probability of breaking the Chinese herbal medicine is avoided, and the integrity of the Chinese herbal medicine is ensured. The sliding block 71 is provided with four, and every two sliding blocks 71 are supported by three sets of rubbing members 74 arranged uniformly along the circumference of the support rod 7, that is, four sliding blocks 71 are slidingly arranged on the support rod 7, two sliding blocks 71 form a group, three connecting rods 73 are uniformly hinged to each sliding block 71 along the circumference, and the other end of the two connecting rods 73 on the same group of sliding blocks 71 is hinged to a rubbing member 74. Of course, the lengths of the two connecting rods 73 can be different, that is, different rubbing forces can be realized for the Chinese herbal medicine, and the cleaning efficiency of the Chinese herbal medicine is improved.

[0023] One end of the support rod 7 is connected with the closed end of the fixed cylinder 2 through a bearing and is fixed with the output end of the second rotary drive mechanism 8. The second rotary drive mechanism 8 drives the support rod to rotate, and in use, the rotating direction between the support rod 7 and the screen cylinder 3 is opposite, and the second rotary drive mechanism 8 can be a servo motor and can control the intermittent rotation of the support rod 7. Further, one end of the support rod 7 close to the inlet 21 is provided with a spiral blade 76. At this time, when the traditional Chinese medicinal materials enter the fixed cylinder 2 through the inlet 21, the spiral blade 76 rotates with the support rod 7 to deliver the traditional Chinese medicinal materials into the screen cylinder 3. Further, the support rod 7 is sleeved with a protection cylinder 75, the protection cylinder 75 is provided with a sliding groove 751 which is in sliding cooperation with the connecting rod 73, one end of the protection cylinder 75 close to the fixed cylinder 2 is fixed with the support rod 7, and the spiral blade 76 is arranged on the outer wall of the protection cylinder 75.

Further, a flexible blocking plate can be arranged on the side wall of the sliding groove 751 to block the opening of the sliding groove 751, and when the connecting rod 73 moves, the flexible blocking plate is extruded to deform to make room, which can block the sliding groove 751 to avoid the traditional Chinese medicinal materials entering the protection cylinder 75 and can ensure that the movement of the sliding block 71 and the connecting rod 73 is not interfered.

[0024] In this way, the support rod 7 arranged in the screen cylinder 3 is used to install and drive the rubbing piece 74 to rotate to rub the traditional Chinese medicinal materials in the screen cylinder 3, so that they rub against each other, and then the impurities on the surface of the traditional Chinese medicinal materials fall off. When the second rotary drive mechanism 8 drives the support rod 7 to rotate, the rubbing piece 74 rotates, and due to the sliding cooperation between the sliding block 71 and the support rod 7, under the action of centrifugal force, the rubbing piece 74 moves radially away from the support rod 7, the two sliding blocks 71 move close to each other, and the first elastic member 72 is compressed. At this time, the distance between the rubbing piece 74 and the inner wall of the screen cylinder 3 is reduced, and the rubbing force is increased. When the support rod 7 stops rotating, due to the resetting action of the first elastic member 72, the two sliding blocks 71 move away from each other, the rubbing piece 74 moves towards the support rod 7, the distance between the rubbing piece 74 and the inner wall of the screen cylinder 3 increases, and the rubbing force decreases. In this way, by controlling the intermittent rotation of the support rod 7 through the second rotary drive mechanism 8, different rubbing forces can be provided for the traditional Chinese medicinal materials in the screen cylinder 3, thereby improving the cleaning effect.
