[0021] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0022] Such as Figure 1, Figure 2 As shown in the figure, the utility model provides an impurity removal device for tea processing, including a base mechanism 1. Above the base mechanism 1, a driving mechanism 2 is arranged. Above the driving mechanism 2, a screening and impurity removal mechanism 3 is arranged. Between the screening and impurity removal mechanism 3 and the driving mechanism 2, an impurity collection mechanism 5 is arranged. Behind the driving mechanism 2, a blowing mechanism 4 is arranged. The driving mechanism 2 includes a screening platform plate 21. At the bottom of the screening platform plate 21, a driving motor 22 is fixedly installed. The output shaft of the driving motor 22 is fixedly installed with a gear 23. On the top left side of the screening platform plate 21, a through groove 24 is opened. The screening and impurity removal mechanism 3 includes a bearing 31. The bottom of the bearing 31 is fixedly installed on the top right side of the screening platform plate 21. The inner ring of the bearing 31 is fixedly installed with a screening and impurity removal barrel 32. A plurality of screening holes 33 are arranged in an outer circumferential array on the outer package of the screening and impurity removal barrel 32. On the left side of the outer wall of the screening and impurity removal barrel 32, an external tooth ring 34 is fixedly installed. Above the gear 23, it passes through the through groove 24 to the upper part of the screening platform plate 21 and meshes with the lower part of the external tooth ring 34. At the left center of the screening hole 33, a motor 35 is fixedly installed. The output shaft of the motor 35 penetrates into the inner cavity of the screening and impurity removal barrel 32, and four connecting rods 36 are fixedly installed on both the front and rear sides. The other ends of the connecting rods 36 are fixedly installed with scraping plates 37. On the side of the two scraping plates 37 away from the connecting rods 36, silica gel strips 38 are fixedly installed. The other sides of the two silica gel strips 38 are lapped with the inner wall of the screening and impurity removal barrel 32.

[0023] When screening and removing impurities, by starting the driving motor 22 at the bottom of the screening platform plate 21, the gear 23 can rotate clockwise. Cooperating with the meshing between the part of the gear 23 passing through the through groove 24 and the external tooth ring 34 on the outer wall of the screening and impurity removal barrel 32, the screening and impurity removal barrel 32 can be driven to rotate within the inner ring of the bearing 31, making the tea inside tumble. At the same time, by starting the motor 35 at the left end of the screening and impurity removal barrel 32, the scraping plates 37 connected by the connecting rods 36 on both the front and rear sides of its output shaft can be driven to rotate counterclockwise within the inner circle of the screening and impurity removal barrel 32. By using the fitting of the silica gel strips 38 with the inner wall of the screening and impurity removal barrel 32, it can effectively prevent the tea from adhering to the inner wall of the screening and impurity removal barrel 32 and blocking the screening holes 33. At the same time, it can also stir the tea, making it easier for impurities to fall through the screening holes 33.

[0024] As Figure 3 , Figure 4 ​As shown in the figure, the air blowing mechanism 4 includes a vertical plate 41. The lower front side of the vertical plate 41 is fixedly connected to the rear side of the screening platform plate 21. An electric air pump 42 is fixedly installed at the lower rear side of the vertical plate 41. The output end of the electric air pump 42 is fixedly connected to an L-shaped air pipe 43. The front end of the horizontal part of the L-shaped air pipe 43 penetrates to the front side of the vertical plate 41 and is fixedly connected to an air delivery box 44. The air delivery box 44 is located directly above the screening and impurity removal barrel 32. A plurality of jet nozzles 45 are fixedly connected to the bottom of the air delivery box 44. The mutual spacing between the plurality of jet nozzles 45 is the same as the spacing between the plurality of screening holes 33 in the left-right direction. A support plate 46 is fixedly installed above the right side of the vertical plate 41. The impurity collection mechanism 5 includes a collection frame 51. The collection frame 51 is fixedly installed on the top of the screening platform plate 21. Arc grooves 52 penetrating through its inner cavity are provided on both the left and right sides of the collection frame 51. A draw hole 53 penetrating through its inner cavity is provided at the front end of the collection frame 51. An impurity collection drawer 54 is arranged at the bottom of the inner cavity of the collection frame 51. The front end of the impurity collection drawer 54 penetrates through the draw hole 53 to the front side of the collection frame 51;

[0025] While the silica gel strip 38 scrapes the inner wall of the screening and impurity removal barrel 32, by starting the electric air pump 42 at the rear side of the vertical plate 41, compressed gas is input into the inner cavity of the air delivery box 44 through the L-shaped air pipe 43, and through a plurality of jet nozzles 45 at the bottom of the air delivery box 44, the screening holes 33 of the rotating screening and impurity removal barrel 32 passing below the jet nozzles 45 are blown, so as to more effectively blow off the tea leaves adhering to and blocking the screening holes 33. The impurities falling through the screening holes 33 of the screening and impurity removal barrel 32 will directly fall into the impurity collection drawer 54 in the inner cavity of the collection frame 51 below the screening and impurity removal barrel 32. The left and right ranges of the screening holes 33 opened on the overall screening and impurity removal barrel 32 are between the two arc grooves 52, so that the impurities falling below can completely fall into the impurity collection drawer 54. When discharging is required, the impurity collection drawer 54 can be pulled out of the collection frame 51 through the draw hole 53 for cleaning.

[0026] As Figure 5As shown in the figure, the base mechanism 1 includes a placement bottom plate 11. On the top right side of the placement bottom plate 11, a side vertical plate 12 is fixedly installed. Above the front side of the side vertical plate 12, a bracket 13 is fixedly installed. At the top of the bracket 13, a flipping motor 14 is fixedly installed. The output shaft of the flipping motor 14 is fixedly connected to the front right side of the screening platform plate 21. At the center of the top of the placement bottom plate 11, a weight 15 is fixedly installed. On the top left side of the placement bottom plate 11, two placement rods 16 are fixedly installed. The tops of the two placement rods 16 are both in contact with the bottom of the screening platform plate 21 in a horizontal state. Above the right side of the side vertical plate 12, an L-shaped limiting plate 17 is fixedly installed. The left side of the vertical part of the L-shaped limiting plate 17 is in contact with the right side of the screening platform plate 21 in a vertical state. The bottom end of the vertical support plate 46 is on the same horizontal line as the bottom end of the placement bottom plate 11. At the eccentric position at the top of the screening and impurity removal barrel 32, a feeding pipe 321 is fixedly connected. At the uppermost part of the inner circle of the feeding pipe 321, a sealing cover 322 is installed by threading. At the lowermost part of the inner circle of the screening and impurity removal barrel 32, a discharge threaded cover 323 is installed by threading;

[0027] By starting the flipping motor 14 at the top of the bracket 13 on the front side of the side vertical plate 12, the overall screening platform plate 21 can be driven to flip until it stops against the vertical part of the L-shaped limiting plate 17. At this time, the screening and impurity removal barrel 32 is in a vertical state as a whole. By using the contact of the bottom end of the support plate 46 with the ground and the weight 15 on the top of the placement bottom plate 11, the center of gravity of the placement bottom plate 11 can be ensured to be stable. At this time, by rotating and removing the discharge threaded cover 323, the tea leaves in the screening and impurity removal barrel 32 can be taken out. After taking out, the discharge threaded cover 323 is rotated and sealed at the bottom of the screening and impurity removal barrel 32, and the sealing cover 322 at the top of the feeding pipe 321 is rotated and opened. Then, the tea leaves that need to be decontaminated can be added again, and the output shaft of the flipping motor 14 is reversed until the bottom of the screening platform plate 21 stops against the tops of the two placement rods 16. At this time, the screening and impurity removal barrel 32 remains in a horizontal state. Then, the impurity collection drawer 54 that has been pulled out is pushed back into the collection frame 51 through the pulling hole 53 again, and the decontamination work can be carried out again.

[0028] Next, the working principle of the impurity removal device for tea processing will be specifically described.

[0029] As Figures 1-5As shown in the figure, during screening and impurity removal, by starting the drive motor 22 at the bottom of the screening platform plate 21, the gear 23 can be rotated clockwise. The meshing between the part of the gear 23 passing through the through slot 24 and the external gear ring 34 on the outer wall of the screening and impurity removal barrel 32 can drive the screening and impurity removal barrel 32 to rotate within the inner ring of the bearing 31, causing the tea leaves inside to tumble. At the same time, by starting the motor 35 at the left end of the screening and impurity removal barrel 32, the scraper 37 connected to the connecting rods 36 on both sides of the output shaft can be driven to rotate counterclockwise within the inner ring of the screening and impurity removal barrel 32. By using the fitting of the silica gel strip 38 with the inner wall of the screening and impurity removal barrel 32, it can effectively prevent the tea leaves from adhering to the inner wall of the screening and impurity removal barrel 32 and blocking the screening holes 33. At the same time, it can also stir the tea leaves, making it easier for the impurities to fall through the screening holes 33. While the silica gel strip 38 scrapes the inner wall of the screening and impurity removal barrel 32, by starting the electric air pump 42 at the rear side of the vertical plate 41, the compressed gas can be input into the inner cavity of the air delivery box 44 through the L-shaped air pipe 43 and blown through several air nozzles 45 at the bottom of the air delivery box 44 onto the screening holes 33 of the rotating screening and impurity removal barrel 32 passing below the air nozzles 45, so as to more effectively blow off the tea leaves adhering to and blocking the screening holes 33. The impurities falling through the screening holes 33 of the screening and impurity removal barrel 32 will directly fall into the impurity collection drawer 54 within the inner cavity of the collection frame 51 below the screening and impurity removal barrel 32. The left and right ranges of the screening holes 33 opened on the overall screening and impurity removal barrel 32 are between the two arc grooves 52, so that the impurities falling below can completely fall into the impurity collection drawer 54. When discharging is required, the impurity collection drawer 54 can be pulled out through the pulling hole 53 from the collection frame 51 for cleaning, and it does not need to be put back temporarily after being pulled out. By starting the flipping motor 14 at the top of the front side bracket 13 of the side vertical plate 12, the overall screening platform plate 21 can be driven to flip until it stops against the vertical part of the L-shaped limiting plate 17. At this time, the screening and impurity removal barrel 32 is in a vertical state as a whole, and the center of gravity of the placement bottom plate 11 is ensured to be stable by the contact of the bottom end of the support plate 46 with the ground and the weight 15 on the top of the placement bottom plate 11. At this time, by rotating and removing the discharge threaded cover 323, the tea leaves in the screening and impurity removal barrel 32 can be taken out. After taking out, the discharge threaded cover 323 is rotated and sealed at the bottom of the screening and impurity removal barrel 32, and the sealing cover 322 at the top of the feeding pipe 321 is rotated and opened, and then the tea leaves to be impurity-removed can be added again. Then, the output shaft of the flipping motor 14 is reversed until the bottom of the screening platform plate 21 stops against the tops of the two placement rods 16. At this time, the screening and impurity removal barrel 32 remains in a horizontal state. Then, the pulled-out impurity collection drawer 54 is pushed back into the collection frame 51 through the pulling hole 53 again, and the impurity removal work can be carried out again.

[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
