[0007] The system includes a screening assembly mounted on the upper part of the base; fan blades mounted on the side of the discharge channel; and a transmission assembly connected to the fan blades. The screening assembly is used to screen the tea leaves inside the screening frame, and the transmission assembly is used to drive the fan blades to rotate and generate airflow.

[0008] Preferably, the screening component includes a drive motor and a first bevel gear. The drive motor is fixedly mounted on the outside of the base, and the output end of the drive motor is fixedly connected to the first bevel gear.

[0009] Preferably, the screening assembly further includes a second bevel gear, a rotating shaft, a double connector, and a vibrating plate. The rotating shaft is rotatably connected to the inner side of the base, and the bottom of the rotating shaft is fixedly connected to the second bevel gear, which meshes with the outer first bevel gear. The upper end of the rotating shaft is fixedly connected to the double connector, and the other side of the double connector is rotatably connected to the outer side of the vibrating plate. The vibrating plate is set on the upper end of the base, and the upper end of the vibrating plate is fixedly connected to a screening frame.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the integrated tea sieving and grading device is equipped with:

[0016] 1. Multi-stage screening structure: In this structure, the tea leaves to be processed fall onto the upper end of the screening frame through the discharge channel. At this time, the drive motor is activated, and the output end of the drive motor drives the first bevel gear to rotate. The first bevel gear meshes with the second bevel gear, which in turn drives the second bevel gear to rotate. The rotation of the second bevel gear drives the rotating shaft to rotate. The rotating shaft drives the screening frame on the upper end of the vibrating plate to swing through the double joint connection. The high-speed swing of the screening frame generates a vibration, which causes the tea leaves at the upper end to move downward along the inclined surface of the screening frame.

[0017] Furthermore, as the tea leaves move downwards along the screening rack, they pass through the first, second, and third screens in sequence. Larger tea leaves fall through the first screen and are discharged inside the first outlet, medium-sized tea leaves fall through the second screen and are discharged through the second outlet, and smaller tea leaves fall through the third screen and are discharged through the third outlet. Through multi-stage screening, the tea leaves are sorted. This structure not only improves the efficiency of tea leaf screening but also saves a lot of manpower.

[0018] 2. Dust removal structure: When the output end of the drive motor rotates, it drives the concentric shaft to rotate through the transmission belt. The rotation of the concentric shaft will drive the fan blades at the end to rotate as well. The rotation of the fan blades will generate wind force, which will blow away light objects such as residue and dust in the tea leaves, thereby improving the quality of the tea leaves.
