[0025] Both side walls at the two ends of the installation frame 2 are slidably connected through two limit rods 7. A sliding frame 6 is fixedly installed between the four limit rods 7. A driving mechanism is arranged between the inner bottom of the installation frame 2 and the bottom of the sliding frame 6. The driving mechanism includes a limit frame 15 fixedly installed on the bottom of the sliding frame 6. A driving motor 24 is fixedly installed on the inner bottom of the installation frame 2. The end of the output shaft of the driving motor 24 is fixedly installed with a circular disk 16. A driving rod 17 is fixedly installed on the top of the circular disk 16. The driving rod 17 extends into the limit frame 15 and is slidably connected with it. Through the setting of the driving mechanism, it can drive the sieve plate 10 to vibrate left and right to realize the screening operation of traditional Chinese medicine materials;

[0026] A collection mechanism is arranged at the top of the bottom end of the sliding frame 6. The collection mechanism includes a stop frame 8 fixedly installed on the top of the bottom end of the sliding frame 6. A collection basin 9 is placed on the sliding frame 6. The collection basin 9 is located inside the stop frame 8. Through the setting of the collection mechanism, it can centrally collect the screened stones and soil, facilitating subsequent processing of them;

[0027] A sieve plate 10 is fixedly installed on the sliding frame 6. Two blocking plates 11 arranged front and back are fixedly installed on the top of the sieve plate 10. A guide plate 12 arranged obliquely is fixedly installed on the side wall of the sieve plate 10. A cleaning mechanism is arranged on the installation frame 1. The bottom of the cleaning mechanism abuts against the top of the sieve plate 10, and the end of the cleaning mechanism abuts against the side wall of the plugging mechanism. The cleaning mechanism includes an electric slide rail 5 fixedly installed on the installation frame 1. An electric slider 23 is slidably connected inside the electric slide rail 5. A first push plate 18 is fixedly installed on the front side wall of the electric slider 23. Two connecting rods 14 and two fixed rods 19 are fixedly installed on the side wall of the first push plate 18. The ends of the two fixed rods 19 are jointly fixedly installed with a second push plate 20. The bottoms of the first push plate 18 and the second push plate 20 both abut against the top of the sieve plate 10. The ends of the two connecting rods 14 both abut against the side wall of the plugging member 13. Through the setting of the cleaning mechanism, when screening traditional Chinese medicine materials, it can automatically clean the traditional Chinese medicine materials on the sieve plate 10, eliminating the operation of manual cleaning by the operator and reducing the workload of the operator.

[0028] The functional principle of the present utility model can be described through the following operation methods:

[0029] When screening traditional Chinese medicinal materials, first, the operator places the traditional Chinese medicinal materials in the feeding hopper 3, and then starts the driving motor 24. The driving motor 24 drives the circular disk 16 to rotate, and the circular disk 16 drives the driving rod 17 to rotate. When the driving rod 17 rotates, it drives the sliding frame 6 to shake left and right by squeezing the limiting frame 15, and the sliding frame 6 drives the sieve plate 10 to shake left and right. At this time, the electric slide rail 5 is turned on, and the electric slide rail 5 drives the electric slider 23 to move leftward. The electric slider 23 drives the first push plate 18 to move leftward. The first push plate 18 drives the second push plate 20 to move leftward through the fixing rod 19. In addition, the first push plate 18 drives the connecting rod 14 to move leftward. When the connecting rod 14 moves leftward, it squeezes the blocking member 13 to slide, so that the blocking member 13 disengages from the blocking of the discharge pipe 4. At this time, the traditional Chinese medicinal materials in the feeding hopper 3 fall onto the sieve plate 10 through the discharge pipe 4, and the shaking sieve plate 10 screens them. The screened soil and stones fall into the collection basin 9 through the sieve plate 10 for collection, and the traditional Chinese medicinal materials stay on the sieve plate 10. When the sieve plate 10 shakes left and right, the bottoms of the first push plate 18 and the second push plate 20 always abut against the top of the sieve plate 10. When there are more traditional Chinese medicinal materials on the sieve plate 10 and they need to be cleaned, the operator starts the electric slide rail 5 to drive the electric slider 23 to slide rightward. The electric slider 23 drives the first push plate 18 to slide rightward. The first push plate 18 drives the connecting rod 14 and the second push plate 20 to slide rightward. The connecting rod 14 gradually disengages from the pressing of the blocking member 13. At this time, the blocking member 13 slides rightward under the action of the spring 22's pulling force and blocks the discharge pipe 4. The second push plate 20 slides rightward to push the traditional Chinese medicinal materials to move rightward, and the traditional Chinese medicinal materials fall onto the guiding plate 12 through the right side of the sieve plate 10 and are collected after being guided by the guiding plate 12. After the traditional Chinese medicinal materials are cleaned, the operator starts the electric slide rail 5 again to drive the electric slider 23 to move to the leftmost side to continue the screening work of the traditional Chinese medicinal materials.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
