Description

Technical Field

[0001] The utility model relates to the technical field of rotary screens, in particular to a rotary screen for making tea. Background Art

[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea tree. Tea processing is also called "tea making", which is the process of making various semi-finished tea or finished tea through various processing procedures of fresh tea leaves. In the process of tea making, the tea leaves are often screened through a rotary screen to remove impurities;

[0003] For example, the utility model patent with Chinese patent publication number CN217094306U discloses a rotary screen for tea making, including a mounting bracket, support rings are fixedly provided on both sides of the top of the mounting bracket, a rotary screen ring is inserted and connected between the two support rings, a protective connecting plate is fixedly provided between the inner walls of the mounting bracket, the protective connecting plate is located directly below the rotary screen ring, a fixed screen is fixedly provided between the inner walls of the rotary screen ring, a feeding slot is opened on one side of the top of the rotary screen ring, mounting connecting plates are fixedly provided on both sides of the inner wall of the feeding slot, and an adjustment shaft is fixedly provided at the center of one side of each mounting connecting plate;

[0004] It was found during use of the above-mentioned prior art that the device loses its limit by removing the limit bolt, and then the pull ring is pulled to flip the feed cover around the adjusting shaft. When the feed cover and the rotating screen ring are in a vertical direction, the tea leaves to be screened can be placed on the fixed screen inside the rotating screen ring through the feed slot. However, the loading method of the device is relatively complicated, and the screening work must be stopped each time the material is loaded, which takes a lot of time. The larger tea leaves left in the screen after screening are also difficult to remove, and it is also inconvenient to inspect and replace the screen, which reduces work efficiency and leads to poor practicality.
