[0002] Tea is generally made from the leaves and buds of the tea tree. After a series of processing, it becomes the tea that people are familiar with. Tea has a long history of drinking and a profound cultural heritage all over the world. It is an indispensable part of the daily life of many people.

[0003] In the process of tea preparation and production, tea leaves need to be screened to distinguish the quality of tea leaves, so as to facilitate the subsequent classification and processing of tea leaves. Existing tea screening equipment usually uses a motor to drive the screening barrel to rotate axially, so as to screen the tea leaves in the screening barrel.

[0004] However, when the tea screening device of this structure is used, tea leaves are easily clogged in the sieve holes of the screening barrel, thereby affecting the screening efficiency. In addition, the tea screening device using the screening barrel to screen tea leaves can only complete one screening, and the screening effect is not good. Utility Model Content

[0032] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0033] Example

[0034] The specific implementation of the utility model is as follows Figure 1-4 As shown, a tea bud screening device comprises an air selection box 2, a screening box 1 connected to the air selection box 2 is installed on the top of the air selection box 2, and an opening 3 is provided on the top of the screening box 1. Among them, a fixed plate 4 is horizontally provided on the inner wall of one side of the screening box 1, a screening basket 5 is rotatably provided on the upper plate surface of the fixed plate 4, and a driving mechanism for driving the screening basket 5 is provided above the screening basket 5. An L-shaped corner frame 8 is fixedly provided on the inner wall of the screening box 1 and is arranged along the side wall and lower surface of the screening basket 5. The corner frame 8 is provided with bristles 9 on the side close to the screening basket 5. In addition, a collection box 10 that can be drawn out from one side is provided in the air selection box 2. A fan 11 is also provided on one side of the air selection box 2, and the output end of the fan 11 is connected to the air selection box 2 through an air duct 12. In this embodiment, the driving mechanism includes a fixed frame 6 horizontally arranged above the screening box 1 and connected to the screening box 1 at one end. A driving motor 7 is provided on the fixed frame 6, and the power output end of the driving motor 7 is transmission-connected to the upper edge of the screening basket 5 through a connecting rod.

[0035] Through the above structure, the screening basket 5 is driven by the driving motor 7 to rotate. Whenever the screening basket 5 passes the brush 9, the brush 9 will dredge its mesh, thereby preventing the tea leaves from blocking the screening basket 5. At the same time, through the fan 11, the weight difference between new and old tea leaves can be used to perform a second screening of the tea leaves, thereby improving the screening effect.

[0036] Regarding this device, a scraper 13 matching the inner diameter of the screening box 1 is provided on the lower surface of the screening basket 5. The scraper 13 rotates with the screening basket 5 and can clean the tea leaves that fall on the fixed plate 4, thereby preventing the tea leaves from being stuck between the fixed plate 4 and the screening basket 5. In this embodiment, in order to avoid wear of the fixed plate 4 and ensure the scraping effect, the scraper 13 is a silicone scraper.

[0037] At the same time, a plug hole 14 is provided on the upper surface of the air selection box 2 near the air duct 12, and a filter 15 that can block the outlet of the air duct 12 is detachably plugged into the plug hole 14. The filter 5 is mainly used to block tea leaves from entering the air duct 12, thereby preventing the fan 11 from malfunctioning. In this embodiment, a limit plate 16 is provided on the upper edge of the filter 15, and the size of the limit plate 16 is larger than the size of the plug hole 14. Such a design can effectively prevent the filter 5 from falling into the plug hole 14, and it is also convenient to take it out.

[0038] In addition, a conical guide hopper 17 is provided below the screening basket 5. A rotating rod 18 is connected to the bottom of the screening basket 5, and the rotating rod 18 passes through the fixed plate 4 and extends into the guide hopper 17. A spiral feeding blade 19 is fixed on the rotating rod 18. The guide hopper 17 cooperates with the rotating feeding blade 19 to evenly deliver the tea leaves screened for the first time to the air separation box 2.

[0039] Furthermore, a partition plate 20 is provided in the collecting box 10, which can divide the collecting box 10 into two storage areas along the air supply direction, and the partition plate 20 is arranged at an angle. The partition plate 20 divides the collecting box 10 into two areas, and the tea leaves can be screened again under the action of the fan 11. At the same time, in order to facilitate the pulling out of the collecting box 10 and observe the amount of tea leaves in the collecting box 10, a handle 21 is provided on the outer wall of the pulling side of the collecting box 10, and the side wall of the collecting box 10 on the side where the handle (21) is provided is a transparent plate.

[0040] The details of how to use the device are as follows:

[0041] First, the driving motor 7 and the fan 11 are started respectively, and the driving motor 7 drives the screening basket 5 to rotate; then, the tea leaves are introduced into the screening basket 5, and the tea leaves that meet the standards are screened out under the uniform and stable rotation of the screening basket 5 and fall onto the feeding blades 19 below; at the same time, the feeding blades 19 are driven by the rotating rod 18 to rotate, so that the tea leaves on the feeding blades 19 are evenly dropped into the air separation box 2.

[0042] Then, the fan 11 blows air, and the old tea leaves are blown farther due to their lighter weight and fall into the area of ​​the collecting box 10 at the end far from the fan 11, while the new tea leaves fall on the side closer to the fan 11. During the rotation of the screening basket 5, the brush 9 clears the tea leaves that block the mesh of the screening basket 5, so that the screening basket 5 is unobstructed.

[0043] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
