Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a grading device for tea processing. Background Art

[0002] Tea leaves refer to the leaves and buds of the tea plant. They are also known as tea, jiǎ, ming, and chuǎn. They refer to the leaves of the evergreen shrub tea plant that can be used to make tea, as well as beverages made from these leaves.

[0003] For example, patent number CN212442005U is a grading device for tea processing, including a screening chamber and a feed hopper, wherein a first screening plate and a second screening plate are arranged at intervals in the screening chamber; the first screening plate includes a first screen and a first fixed plate arranged at both ends of the first screen, and the second screening plate includes a second screen and a second fixed plate arranged at both ends of the second screening plate body, wherein the aperture of the first screen is larger than the aperture of the second screen. The above document still has deficiencies. When in use, one end of a spring is arranged in the fixing sleeve, and the spring is inserted into the fixing column. A base is arranged at the bottom end of the fixing column, and the fixing sleeve is respectively connected to the first fixing plate and the second fixing plate by threads. The base is connected to the first support plate and the second support plate by bolts respectively. The whole structure is simple to manufacture and install, and the effect is good. However, when the grading device in the above document screens the tea leaves, the tea leaves will press the inclined direction of the sieve plate to move, and the movement speed of the tea leaves is relatively fast. The tea leaves may be discharged without being screened. When the tea leaves are graded, the movement speed of the tea leaves on the sieve plate is relatively fast, which makes the grading efficiency of the tea leaves low. At the same time, when the tea leaves are graded, adding too much tea leaves will affect the grading effect of the tea leaves. If too little tea leaves are added, the grading efficiency of the tea leaves will be reduced. When the tea leaves are graded, it is not convenient to control the amount of tea leaves added.
