Description

Technical Field

[0001] This utility model belongs to the technical field of tea processing equipment, specifically relating to a tea screening machine. Background Technology

[0002] A tea sorting machine is a type of tea processing equipment, mainly used for sorting tea leaves during the tea processing process. For example, the existing patent with publication number CN208018962U discloses "a tea sorting machine, with a fixed neck at the top of the main body, a feed hopper rotatably fixed to the fixed neck, a prismatic protrusion on the inner surface of the feed hopper neck, multiple annular grooves on the inner surface of the fixed neck, several annular protrusions adapted to the annular grooves on the outer surface of the feed hopper, four rotating handles on the outer surface of the feed hopper neck at a position higher than the fixed neck, and multiple inclined sieve plates inside the main body". It can be seen that the application describes a common tea sorting machine, which relies on multiple inclined sieve plates inside the sorting machine to sort the tea leaves.

[0003] In existing tea sorting machines, the sorted tea leaves are discharged from the outlets on both sides of the machine. Operators need to use external containers to collect the tea leaves at the bottom of the outlets. When the container is full of sorted tea leaves, it is necessary to replace the container or empty the tea leaves. However, since no sealing structure is designed on each outlet, tea leaves continue to be discharged and fall to the ground while the operator is replacing the container or emptying the tea leaves. Therefore, this utility model proposes a tea sorting machine. Utility Model Content

[0030] The top surface of the screening machine body 1 is provided with a feeding port 2 for feeding the tea to be screened, and the inside of the screening machine body 1 is provided with a plurality of inclined screens.

[0031] Embodiment 2

[0032] Please refer to Figures 1 to 4 As the second embodiment of the utility model, this embodiment is based on the previous embodiment, and the difference is that the rubber protrusion 331 and the base 36 and the like can be arranged to limit the position when the operator laterally pulls and rotates downward the blocking plate 33 to cover the bottom end of the discharge port 4.

[0033] Specifically, the bottom surface of the discharge port 4 is welded and fixed with the base 36, and the side surface of the base 36 is provided with a positioning clamping groove 361, and the inner surface of the blocking plate 33 is glued and fixed with a rubber protrusion 331 corresponding to the positioning clamping groove 361. The rubber protrusion 331 is made of rubber material and will elastically deform when being extruded. When the operator laterally pulls and rotates downward the blocking plate 33 to cover the bottom end of the discharge port 4, the rubber protrusion 331 will enter the positioning clamping groove 361, thereby limiting the position of the blocking plate 33 at this time, ensuring the blocking stability of the blocking plate 33 to the bottom end of the discharge port 4. Subsequently, the blocking plate 33 can be laterally moved to make the rubber protrusion 331 move out of the positioning clamping groove 361, and the blocking plate 33 can be smoothly rotated upward and reset.
