Description

Technical Field

[0001] This utility model belongs to the technical field of screening and grading devices, specifically a screening and grading device for processing Chinese medicinal herbs. Background Technology

[0002] In the processing of Chinese medicinal herbs, the dried slices need to be graded to classify herbs of different sizes. Currently, there are generally two methods for grading Chinese medicinal herbs: one is manual screening, which is labor-intensive and inefficient; the other is using an air classifier. However, during air classification, because the Chinese medicinal herbs are sheet-like, the angle of the slices is random as they fall. The air resistance varies depending on whether the slices are vertical or horizontal, resulting in grading errors and poor performance. Therefore, this application proposes a screening and grading device for processing Chinese medicinal herbs. Utility Model Content

[0022] Depend on Figures 1 to 3 This utility model discloses a screening and grading device for processing Chinese herbal medicine slices, comprising a feeding mechanism 1 and a screening mechanism 2. The feeding mechanism 1 is located at one end of the side of the screening mechanism 2, and two support seats 3 are fixedly installed at the bottom end of the feeding mechanism 1. The screening mechanism 2 consists of a supporting base plate 4, four strong supporting springs 5, two supporting plates 6, a screening frame 7, a first screen 8, a second screen 9, and a vibration motor 10. The strong supporting springs 5 ​​are fixedly connected to the four corners of the top of the supporting base plate 4, the supporting plates 6 are fixedly connected to the top of the strong supporting springs 5, the screening frame 7 is fixedly connected to the top of the supporting plates 6, the first screen 8 and the second screen 9 are both fixedly connected to the bottom of the screening frame 7, and the vibration motor 10 is fixedly connected to the bottom of the screening frame 7. The screening frame 7 has an inclined structure.

[0023] In use, the feeding mechanism 1 feeds the Chinese herbal medicine slices. The important slices enter the screening mechanism 2. The vibration motor 10 drives the screening frame 7 to vibrate. The screening frame 7 is elastically supported by four strong support springs 5 ​​and two support plates 6, which improves the mobility of the screening frame 7. The first screen 8 and the second screen 9 screen the Chinese herbal medicine slices for screening and grading. The smaller Chinese herbal medicine slices are discharged through the first screen 8, the slightly larger Chinese herbal medicine slices are discharged through the second screen 9, and the largest Chinese herbal medicine slices are discharged along the discharge port at the other end of the screening frame 7.

[0024] Depend on Figures 2 to 4 Given that the mesh diameter of the second screen 9 is larger than that of the first screen 8, two arc-shaped baffles 11 are fixedly installed on one side of the inside of the screening frame 7, and two arc-shaped baffles 12 are fixedly installed on the other side of the inside of the screening frame 7. The arc-shaped baffles 11 and 12 are alternately installed. A discharge chute 13 located at the bottom of the first screen 8 is fixedly installed on one side of the bottom of the screening frame 7, and a discharge chute 14 located at the bottom of the second screen 9 is fixedly installed on the other side of the bottom of the screening frame 7. Several limiting sleeves 15 are fixedly installed on both sides of the top of the screening frame 7. A cover plate 16 is installed between the limiting sleeve 15 and the screening frame 7. The cover plate 16 and the limiting sleeve 15 are connected by several locking bolts 17. A slot 18 is opened at the end of the cover plate 16 near the feeding mechanism 1.

[0025] Arc-shaped baffle plate 11 and arc-shaped baffle plate 22 can block the Chinese herbal medicine pieces, slow down the falling speed of the Chinese herbal medicine pieces, thereby improving the screening accuracy. Discharge chute 13 and discharge chute 2 14 can realize the discharge. Cover plate 16 can play a blocking role to prevent the Chinese herbal medicine pieces from falling from the top side due to excessive vibration during screening. The slot 18 can facilitate the Chinese herbal medicine pieces to enter the interior of the screening mechanism 2.

[0026] Depend on Figure 1 and Figure 5 As shown, the feeding mechanism 1 consists of a U-shaped support frame 19, a conveyor belt 20, a drive motor 21, a first pulley 22, a leveling roller 23, a second pulley 24, and a belt 25. The conveyor belt 20 is rotatably connected to the bottom end inside the U-shaped support frame 19. The drive motor 21 is fixedly connected to one end of the side of the U-shaped support frame 19 and connected to the conveyor belt 20. The first pulley 22 is fixedly connected to one of the rollers on the conveyor belt 20. The leveling roller 23 is rotatably connected to one end inside the U-shaped support frame 19 and located at the top of the conveyor belt 20. The second pulley 24 is fixedly connected to one end of the leveling roller 23. The belt 25 is connected between the first pulley 22 and the second pulley 24.

[0027] When the feeding mechanism 1 is working, the drive motor 21 drives the conveyor belt 20 to rotate to achieve feeding. The conveyor belt 20 drives the pulley 1 22 to rotate. The pulley 1 22 drives the pulley 24 to rotate through the belt 25. The pulley 24 drives the material leveling wheel 23 to rotate. The material leveling wheel 23 can flatten the piled-up Chinese herbal medicine pieces, avoiding the concentrated feeding of Chinese herbal medicine pieces and affecting the screening accuracy.

[0028] In operation, the screening mechanism, consisting of a supporting base plate, four strong supporting springs, two supporting plates, a screening frame, a first screen, a second screen, and a vibrating motor, enables the screening and grading of Chinese medicinal herbs, improving screening efficiency and accuracy. The use of arc-shaped baffles one and two slows down the movement of the herbs, further enhancing grading accuracy. Discharge troughs one and two facilitate the unloading of the graded herbs. A feeding mechanism, consisting of a U-shaped supporting frame, a conveyor belt, a drive motor, pulley one, a uniform feeding wheel, pulley two, and a belt, feeds the herbs while improving feeding uniformity and preventing accumulated herbs from entering the screening mechanism simultaneously and affecting the screening effect.
