[0002] Some Chinese medicinal herbs have very small seeds. To improve cultivation efficiency, it is necessary to grade and screen seeds of different diameters and those that are empty or shriveled. A search revealed a seed screening device for Chinese medicinal herb cultivation with application number CN202123071277.8. This application addresses the problems of low efficiency and difficulty in removing empty or shriveled seeds using traditional screening devices, suggesting that empty or shriveled seeds can be removed by washing with water, and that grading and screening can be performed using a vibrating motor.

[0003] However, the above technology has the following problems: the vibration motor is noisy, the machine body has poor working stability, dust is seriously emitted, and the grading effect is not ideal. Further improvements can be made. In addition, the seeds need to be dried after washing, which is a complicated process and wastes a lot of water resources. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grading device for Chinese medicinal herbs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a Chinese herbal medicine seed grading device, comprising a grading box and an inner ring. The inner ring is fixedly installed inside the grading box, and three sets of inner rings are arranged from top to bottom. A first sieve, a second sieve, and a third sieve are fixedly installed from top to bottom on the top surface of the inner ring. A pull rod is slidably connected through the top surface of the grading box, and a second connecting rod is rotatably connected to the top surface of the pull rod via a rotating pin. The other end of the second connecting rod is rotatably connected to a first connecting rod via a rotating pin. The pull rod passes through the first sieve and the second sieve and is fixedly connected to the center position of the first sieve, the second sieve, and the third sieve via a clamping plate. A drive motor is fixedly installed on the top surface of the grading box via a motor frame, and the other end of the drive shaft of the drive motor is fixedly connected to the other end of the first connecting rod. A feed hopper is connected through the top surface of the grading box, and a discharge port is opened on the surface of the grading box located on the top surface of the inner ring. A discharge channel is fixedly connected to the outer side of the discharge port located on the outer wall of the grading box, and an insert plate is inserted through the top surface of the discharge channel.

[0006] Preferably, the bottom surface of the grading box has a bottom opening, and the bottom of the grading box has a funnel-shaped structure.

[0007] Preferably, a cyclone dust collector is installed on one side of the classification box, and the air inlet of the cyclone dust collector is connected to the top of the classification box through an air supply pipe, and the exhaust end of the cyclone dust collector is connected to a centrifugal fan through an air extraction pipe.

[0008] Preferably, the aperture of the first screening mesh is larger than that of the second screening mesh, and the aperture of the second screening mesh is larger than that of the third screening mesh.

[0009] Preferably, the top surface of the insert plate is equipped with a handle, and the height of the insert plate is greater than the height of the discharge channel, and the width of the insert plate is equal to the internal width of the discharge channel.

[0012] Preferably, both the discharge port and the discharge channel adopt an arc-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model adopts a first screening screen, a second screening screen and a third screening screen. When grading and screening Chinese medicine seeds, the Chinese medicine seeds can be put into the grading box from the feed hopper. The Chinese medicine seeds fall onto the top surface of the first screening screen. Then, the drive motor drives the first connecting rod to rotate, which in turn drives the second connecting rod to rotate and drives the pull rod to move up and down. This causes the first screening screen, the second screening screen and the third screening screen to vibrate up and down for screening. The aperture of the first screening screen, the second screening screen and the third screening screen gradually becomes smaller. The Chinese medicine seeds pass through the first screening screen, the second screening screen and the third screening screen in sequence according to their own particle size. The Chinese medicine seeds fall down in stages and are graded, completing the grading and screening. The number of screening grades is large and the grading is more delicate. At the same time, compared with the traditional vibrating screening, this device has less noise, the machine body is more stable and reliable, and the convenience of use is improved.

[0015] (2) This utility model adopts a cyclone dust collector. When the Chinese medicine seeds are graded and screened, the centrifugal fan is started to draw out the air inside the cyclone dust collector. The air inside the grading box carries the dust into the cyclone dust collector along the air conveying pipe. After the cyclone dust collector is removed, the dust is removed, avoiding the problem of dust dispersion and optimizing the working environment. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] Please refer to Figure 1-4 A grading device for Chinese medicinal herbs includes a grading box 1 and an inner ring 2. The inner ring 2 is fixedly installed inside the grading box 1, and three sets of inner ring 2 are arranged from top to bottom. A first sieve 3, a second sieve 4, and a third sieve 5 are respectively fixedly installed on the top surface of the inner ring 2 from top to bottom. The first sieve 3, the second sieve 4, and the third sieve 5 are all flexible structures. A pull rod 6 is slidably connected through the top surface of the grading box 1, and a second connecting rod 22 is rotatably connected to the top surface of the pull rod 6 via a rotating pin 9. The other end of the second connecting rod 22 is rotatably connected to a first connecting rod 8 via the rotating pin 9. The first screening screen 3 and the second screening screen 4 are fixedly connected to the center of the first screening screen 3, the second screening screen 4 and the third screening screen 5 through the clamping plate 20. The top surface of the grading box 1 is fixedly installed with the drive motor 7 through the motor frame 10, and the other end of the drive shaft 21 of the drive motor 7 is fixedly connected to the other end of the first connecting rod 8. The top surface of the grading box 1 is connected to the feed hopper 18, and the surface of the grading box 1 is provided with the discharge port 11 on the top surface of the inner ring 2. The outer side of the discharge port 11 is fixedly connected to the outer wall of the grading box 1 with the discharge channel 12. The top surface of the discharge channel 12 is inserted through the insert plate 13.

[0025] In this implementation plan: When grading and screening Chinese medicinal herbs, the herbs can be fed into the grading box 1 through the feed hopper 18. The herbs fall onto the top surface of the first screening screen 3. Subsequently, the drive motor 7 drives the first connecting rod 8 to rotate, which in turn drives the second connecting rod 22 to rotate and simultaneously moves the pull rod 6 up and down. This causes the first screening screen 3, the second screening screen 4, and the third screening screen 5 to vibrate up and down for screening. The apertures of the first screening screen 3, the second screening screen 4, and the third screening screen 5 gradually decrease. The herbs pass through the first screening screen 3, the second screening screen 4, and the third screening screen 5 in sequence according to their particle size, and the herbs fall down in a graded manner. The device completes grading and screening with multiple gradations, resulting in finer grading. Compared to traditional vibrating screens, this device is quieter, more stable, and more reliable, improving ease of use. When it is necessary to remove the medicinal seeds, the drive motor 7 can be started to rotate the first connecting rod 8 until the other end of the first connecting rod 8 is at its highest point. At this time, the pull rod 6 rises to its highest point, and the first screening screen 3, the second screening screen 4, and the third screening screen 5 form an inverted funnel-shaped structure. The medicinal seeds slide into the discharge port 11. After removing the insert plate 13, the medicinal seeds can be discharged along the discharge channel 12, making material removal very convenient and further improving ease of use.

[0026] Specifically, the bottom surface of the grading box 1 has a bottom opening 19, and the bottom of the grading box 1 has a funnel-shaped structure.

[0027] In this implementation plan: the bottom opening 19 facilitates the outflow of the smallest diameter Chinese medicinal seeds.

[0028] Specifically, a cyclone dust collector 15 is installed on one side of the classification box 1, and the air inlet of the cyclone dust collector 15 is connected to the top of the classification box 1 through the air supply pipe 14, and the exhaust end of the cyclone dust collector 15 is connected to a centrifugal fan 17 through the air extraction pipe 16.

[0029] In this implementation plan: when grading and screening Chinese medicinal seeds, the centrifugal fan 17 is started to draw out the air inside the cyclone dust collector 15. The air inside the grading box 1 carries the dust into the cyclone dust collector 15 along the air supply pipe 14. After being removed by the cyclone dust collector, the dust is removed, avoiding the problem of dust dispersion and optimizing the working environment.

[0030] Specifically, the aperture of the first screening screen 3 is larger than that of the second screening screen 4, and the aperture of the second screening screen 4 is larger than that of the third screening screen 5.

[0031] In this implementation plan: the apertures of the first screening screen 3, the second screening screen 4, and the third screening screen 5 are set according to the required particle size of the Chinese medicinal seeds.

[0032] Specifically, a handle is installed on the top surface of the insert plate 13, and the height of the insert plate 13 is greater than the height of the discharge channel 12, and the width of the insert plate 13 is equal to the internal width of the discharge channel 12.

[0033] In this implementation scheme: the insert plate 13 is convenient to block the seeds during the grading and screening process, so as to prevent the seeds from leaking during the screening process.

[0034] Specifically, the clamping plate 20 is fixedly connected to the pull rod 6, and the clamping plate 20 is fixedly connected to the first screening screen 3, the second screening screen 4, and the third screening screen 5.

[0035] In this implementation plan, the clamps 20 are distributed vertically to provide a fixing function, which is a common fixing structure.

[0036] Specifically, the bottom of the grading box 1 is fixedly equipped with support legs, and the height of the support legs is not less than 50cm.

[0037] In this implementation plan: the support legs facilitate the installation of the grading box 1, and the support legs also facilitate the staff to place the Chinese herbal medicine seed collection trough below the bottom opening 19.

[0038] Specifically, both the discharge port 11 and the discharge channel 12 adopt an arc-shaped structure.

[0039] In this implementation scheme, the arc-shaped discharge port 11 and discharge channel 12 improve the discharge efficiency.

[0040] Working Principle: When grading and screening Chinese medicinal herbs, the seeds are fed into the grading box 1 through the feed hopper 18. The seeds fall onto the top surface of the first screening screen 3. Then, the drive motor 7 drives the first connecting rod 8 to rotate, which in turn drives the second connecting rod 22 to rotate, simultaneously moving the pull rod 6 up and down. This causes the first screening screen 3, the second screening screen 4, and the third screening screen 5 to vibrate and screen. The apertures of the first screening screen 3, the second screening screen 4, and the third screening screen 5 gradually decrease in size. The seeds pass through these screens sequentially according to their particle size, thus being graded and screened step by step. The device features component-level sieving with multiple sieving grades, resulting in finer grading. Compared to traditional vibrating sieving, this device is quieter, more stable, and more reliable, improving ease of use. When it is necessary to remove the medicinal herb seeds, the drive motor 7 can be started to rotate the first connecting rod 8 until the other end of the first connecting rod 8 is at its highest point. At this time, the pull rod 6 rises to its highest point, and the first sieving screen 3, the second sieving screen 4, and the third sieving screen 5 form an inverted funnel-shaped structure. The medicinal herb seeds slide into the discharge port 11. After removing the insert plate 13, the medicinal herb seeds can be discharged along the discharge channel 12, making material removal very convenient and further improving ease of use.

[0041] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
