Description

Technical Field

[0001] The utility model relates to the technical field of tea screening, in particular to a screening mechanism for tea residues. Background Art

[0002] Tea refers to the leaves and buds of the tea tree, the leaves of the evergreen shrub tea tree that can be used to make tea, and beverages brewed from these leaves. Tea contains dust impurities, broken tea leaves and intact tea leaves. During tea production and processing, dust impurities, broken tea leaves and intact tea leaves need to be separated, which is usually done through a related tea impurity removal vibrating screen mechanism.

[0003] The utility model patent with the authorization announcement number CN218360593U discloses a tea impurity removal vibration screen mechanism, which includes a base assembly, a collection assembly is movably connected to the upper surface of the base assembly, and the collection assembly includes a collection box and a first handle, the first handle is fixedly connected to the middle of the two end surfaces outside the collection box, and a notch is provided in the middle of the two ends of the upper surface of the collection box, the four corners of the bottom surface of the collection box are fixedly connected to support blocks, and the middle of the two ends of the bottom surface of the collection box are fixedly connected to sleeves, and a screening assembly is placed in the collection box. The utility model has the advantage of being convenient for quickly cleaning dust impurities and broken tea leaves by setting the collection assembly, and solves the problem that the existing tea impurity removal vibration screen mechanism is usually inconvenient to quickly disassemble the collection mechanism after the dust impurities and broken tea leaves are screened out, so it is not convenient to quickly clean the dust impurities and broken tea leaves screened out, and there are certain limitations in use.

[0004] Although the above utility model can screen tea impurities, in actual use, the collecting mechanism needs to be shaken in the horizontal direction as a whole, so that the tea can only be shaken in the horizontal direction. When screening, the tea accumulates, and only horizontal movement cannot efficiently disperse the tea. In view of this, we propose a screening mechanism for tea residues. Utility Model Content

[0038] During the specific use of the screening mechanism for tea residues of this embodiment, the tea leaves to be screened are first fed into the screening box 151, and then the upper cover 2 is closed by aligning the positioning rod 21 with the positioning hole 113, and then the vibration motor 156 is started to wait for the tea leaves to be screened through the filter 152 under the action of vibration. After the screening is completed, the vibration motor 156 is turned off, the upper cover handle 22 is held to open the upper cover 2, and then the screening support plate 153 can be held to lift the screening mechanism 15 as a whole. At this time, the tea leaves in the screening box 151 are the high-quality tea leaves that have been screened out. After collecting these high-quality tea leaves, the screening mechanism 15 is put back, and then the pull-out handle 141 is held to pull the residue box 14 out of the sliding opening 12, and then the residue filtered out of the residue box 14 can be processed.
