[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a vibrating sieving device for grading fresh tea leaves, comprising: a supporting base plate 1; a first support frame 2 bolted to the top of the supporting base plate 1; a second sieving box 15 placed above the first support frame 2, with a small fresh leaf screen 22 bolted to the inner side of the second sieving box 15; a second support frame 3 bolted to the top of the supporting base plate 1, with a first sieving box 9 positioned above the second support frame 3; a coarse screen 10 installed inside the first sieving box 9, with a powder screen 11 installed inside the first sieving box 9, the powder screen 11 located below the coarse screen 10; a first discharge guide 13 fixed to one side of the first sieving box 9, the first discharge guide 13 cooperating with the powder screen 11; and a reset structure placed on top of the first support frame 2 and the second support frame 3, with both the first sieving box 9 and the second sieving box 15 connected to the reset structure.
[0028] It should be noted that in this embodiment, the fresh tea leaves to be graded and screened are poured onto the coarse screen 10. The output end of the motor 23 drives the rotating support rod 18 and the cam 20 to rotate. When the cam 20 rotates, its protrusion pushes the top frame 19. The top frame 19 drives the connecting support plate 14, the first discharge pipe 24, and the second discharge pipe 25 to move downward. The first discharge pipe 24 drives the first screening box 9 to move downward, and the second discharge pipe 25 drives the second screening box 15 to move downward. The first screening box 9 and the second screening box 15 drive the outer side support plate 8 to move. The side support plate 8 drives the inner limiting slide column 6 to slide inside the limiting support cylinder 5. The side support plate 8 presses the spring 7 at the top of the top fixed support plate 4. When the output end of the motor 23 continues to drive the rotating support rod 18 and the cam 20 to rotate, the spring 7 will reset and... The side support plate 8, screening box 9, and screening box 15 are driven to return to their original positions. The support rod 18 and cam 20 rotate continuously, allowing for continuous screening through the coarse screen 10, powder screen 11, and small fresh leaf screen 22. The coarse screen 10 screens out large leaves, which are then guided out through the discharge guide frame 12 and collected in an external collection container. The fresh leaves screened through the coarse screen 10 enter the powder screen 11, where powder and sand are screened out and discharged through the discharge pipe 24. The fresh tea leaves then pass through the discharge guide 13 to the small fresh leaf screen 22 for final screening. Leaves that fail the screening are guided out through the discharge guide 16, while successfully screened leaves are discharged and collected through the discharge pipe 25.
[0029] In one embodiment, such as Figures 1 to 4 As shown, a first discharge pipe 24 is fixedly connected to the bottom of the first screening box 9, and a second discharge pipe 25 is fixedly connected to the bottom of the second screening box 15. A connecting support plate 14 is welded and fixed between the first discharge pipe 24 and the second discharge pipe 25. A top moving frame 19 is installed at the bottom of the connecting support plate 14 by bolts.
[0030] It should be noted that in this embodiment, the powder and crushed sand separated by the powder screen 11 are guided and discharged through the first discharge pipe 24, and the fresh leaves after being screened by the small fresh leaf screen 22 are guided and collected through the second discharge pipe 25.
[0031] In one embodiment, such as Figures 1 to 4 As shown, a support frame 17 is bolted to the top of the support base plate 1. A rotating support rod 18 is rotatably provided on the inner side of the support frame 17. A cam 20 that cooperates with the jacking frame 19 is fixed to the outer side of the rotating support rod 18.
[0032] It should be noted that in this embodiment, when the rotating support rod 18 rotates, it drives the outer cam 20 to rotate, and the cam 20 pushes the top frame 19, which in turn drives the connecting support plate 14, the first discharge pipe 24, the first screening box 9, the second discharge pipe 25 and the second screening box 15 to move downward as a whole, thus completing the position movement.
[0033] In one embodiment, such as Figure 4 As shown, a motor 23 is bolted to one side of the support frame 17, and the output end of the motor 23 is fixedly connected to the rotating support rod 18.
[0034] It should be noted that in this embodiment, the output end of the motor 23 drives the rotating support rod 18 to rotate, and the rotating support rod 18 drives the outer cam 20 to rotate and adjust.
[0035] In one embodiment, such as Figures 1 to 4 As shown, it also includes a discharge guide frame 12, which is fixed to one side of the No. 1 screening box 9 and cooperates with the coarse screen 10.
[0036] It should be noted that in this embodiment, the coarse blades screened by the coarse screen 10 are removed by the discharge guide frame 12.
[0037] In one embodiment, such as Figures 1 to 5 As shown, the reset structure includes a top fixed support plate 4, a limiting support cylinder 5, and an inner limiting slide column 6. Side support plates 8 are symmetrically arranged above the top fixed support plate 4. The outer sides of the No. 1 screening box 9 and the No. 2 screening box 15 are bolted to the side support plate 8. The bottom of the side support plate 8 and the top of the top fixed support plate 4 are both fixedly connected to the inner limiting slide column 6. The limiting support cylinder 5 is slidably arranged on the outer side of the inner limiting slide column 6. Springs 7 are sleeved on the outer sides of the limiting support cylinder 5 and the inner limiting slide column 6.
[0038] It should be noted that in this embodiment, the inner limiting slide 6 slides within the limiting support cylinder 5, and the spring 7 resets the moving position of the side support plate 8, thereby resetting the moving positions of the first screening box 9 and the second screening box 15.
[0039] In one embodiment, such as Figures 1 to 4 As shown, a guide frame 21 is bolted to the top of the No. 1 screening box 9.
[0040] It should be noted that in this embodiment, the fresh tea leaves are guided into the No. 1 screening box 9 by the guide frame 21 for screening.
[0041] In one embodiment, such as Figures 1 to 4 As shown, a discharge guide cover 16 is fixedly connected to one side of the No. 2 screening box 15.
[0042] It should be noted that in this embodiment, the tea leaves that were not successfully screened by the small fresh leaf screen 22 are discharged through the second discharge guide 16, and the fresh tea leaves are graded and screened.
