[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 5 The utility model provides a raw material drug screening and filtering device, comprising a support leg 1, a guard plate 2 is fixedly installed on the top of the support leg 1, two fixed rods 3 are fixedly installed on the inner surface of the guard plate (2), and the opposite surfaces of the two fixed rods 3 are fixedly connected to a filter box 31, a drug inlet 32 ​​is provided on the top of the filter box 31, a crushing barrel 34 is fixedly installed in the middle of the filter box 31, and a plurality of first grooves 331 are provided at the bottom of the crushing barrel 34, a second motor 36 is fixedly installed on one side of the guard plate 2, the output shaft of the second motor 36 is fixedly connected to a second rotating shaft 361, and two turntables 362 are fixedly connected to the outer surface of the second rotating shaft 361, a sliding rod 37 is movably connected to the top of the turntable 362, and the two sliding rods 37 are fixedly connected to a cross plate 38, and a plurality of dredging rods 39 are fixedly installed on the top of the cross plate 38, a drug discharge pipe 4 is fixedly connected to the bottom of the filter box 31, and the plurality of dredging rods 39 are respectively slidably installed on the inner surface of the first groove 331.

[0026] When processing raw materials, there are large particles and impurities in the raw materials that need to be handled.

[0027] When the present invention is in use, the raw medicine is first injected into the filter box 31 through the medicine inlet 32, and then flows out through the several first grooves 331 on the filter box 31. During the outflow of the raw medicine, impurities and large particles in the raw medicine may block the first grooves 331, resulting in poor flow of the medicine. Therefore, during the drug dispensing process, the second motor 36 output shaft drives the second rotating shaft 361 to rotate, and the second rotating shaft 361 can drive the two turntables 362 to rotate. During the rotation of the turntable 362, it can drive the sliding rod 37 to move up and down, and when the sliding rod 37 moves, it can drive the cross plate 38 and the dredging rod 39 to move up and down. The dredging rod 39 can be inserted into the inner surface of the first groove 331 when moving, and the drug impurities blocked on the inner surface of the first groove 331 are cleaned up, so as to avoid the blockage of the first groove 331 affecting the drug dispensing of the first groove 331.

[0028] Further, such as Figure 2 As shown, there are four guard plates 2, which are grouped in pairs and divided into two groups, and are fixedly installed at the bottom of the guard plates 2 respectively.

[0029] The four supporting legs 1 are evenly arranged at the bottom of the guard plate 2 to support the guard plate 2, and supporting the entire raw material drug screening and filtering device through the four supporting legs 1 can make the filtration process more stable and avoid the raw material drug screening and filtering device from tipping over during the filtration process.

[0030] Further, such as Figure 3 As shown, the drug inlet 32 ​​passes through the inner cavity of the filter box 31, and a limiting rod 363 is fixedly installed in the inner cavity of the filter box 31. Two second grooves 3631 are provided on the top of the limiting rod 363, and the two sliding rods 37 are respectively slidably installed on the inner surface of the second grooves 3631. The second rotating shaft 361 is not in the center of the two limiting rods 363.

[0031] During use of the present invention, when the second motor 36 rotates the turntable 362 via the second rotating shaft 361, since the second rotating shaft 361 is not at the center of the turntable 362, the turntable 362 can lift the sliding rod 37 when it rotates, so that the sliding rod 37 can move up and down with the dredging rod 39 to dredge the first groove 331.

[0032] Further, such as Figure 4 As shown, a first motor 351 is fixedly mounted on one side of the guard plate 2, and an output shaft of the first motor 351 is fixedly connected to a first rotating shaft 35. The first rotating shaft 35 is rotatably connected to the crushing barrel 34 and passes through the crushing barrel 34 and is rotatably connected to one side of the guard plate 2. The first rotating shaft 35 located in the inner cavity of the crushing barrel 34 is fixedly connected to a connecting rod 33, and a connecting column 301 is fixedly connected to the outer surface of the connecting rod 33.

[0033] A plurality of third grooves 3011 are formed on the outer surface of the connecting column 301 , and medicine balls 3012 are rotatably mounted on the inner surfaces of the plurality of third grooves 3011 .

[0034] During use of the present invention, when the raw material medicine enters the filter box 31 through the medicine inlet 32, the first motor 351 can drive the first rotating shaft 35 and the connecting rod 33 to rotate, and the connecting rod 33 drives the connecting column 301 to rotate, and a plurality of crushing balls 3012 are in rotational contact with the inner wall of the crushing barrel 34, and the crushing balls 3012 rotate on the inner surface of the third groove 3011. During this process, the crushing balls 3012 can crush the impurities or large particles in the raw material medicine, so that only impurities remain in the raw material medicine, and there is no situation where large particles in the raw material medicine are not mixed with the medicine liquid.

[0035] Further, such as Figure 5 As shown, a filter plate 41 is fixedly installed on the inner surface of the drug discharge tube 4, a valve 43 is fixedly connected to the bottom of the outer surface of one side of the drug discharge tube 4, and a waste outlet pipe 42 is connected through the outer surface of the drug discharge tube 4. The filter plate 41 is located between the waste outlet pipe 42 and the valve 43.

[0036] During use of the present invention, after the raw material medicine passes through the filter box 31, it will flow out through the medicine discharge pipe 4, and some impurities will remain in the raw material medicine. When passing through the medicine discharge pipe 4, the valve 43 is opened and the raw material medicine will flow out downward, while the impurities in the raw material medicine will remain on the filter plate 41. When it is necessary to clean the impurities, the impurities on the filter plate 41 can be cleaned through the waste pipe 42.

[0037] Working principle: When the present invention is in use, the raw medicine is first allowed to enter the filter box 31 through the medicine inlet 32, and the raw medicine will enter the crushing barrel 34 in the filter box 31 through the medicine inlet 32. Driven by the first motor 351, the first rotating shaft 35 rotates with the connecting rod 33 and the connecting column 301. When the connecting column 301 rotates, a number of crushed medicine balls 3012 will contact and rotate with the inner wall of the crushing barrel 34 by friction. At this time, the large particles in the raw medicine will be crushed and mixed with the raw medicine. Then the raw medicine flows out of the filter box 31 through the first groove 331. Since there are still impurities in the raw medicine, the impurities may block the first groove 331.

[0038] The second motor 36 drives the second rotating shaft 361 and the two turntables 362 to rotate, and the turntable 362 can make the slide bar 37 move up and down with the cross plate 38 and the dredging rod 39 to dredge the first groove 331, and then the raw material medicine flows out through 44. During the outflow process, the raw material medicine is filtered by the filter plate 41, and the impurities remaining on the top of the filter plate 41 are cleaned through the waste pipe 42. The raw material medicine flows out of the drug discharge pipe 4 through the valve 43.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
