[0015] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 2 In the embodiment of a tea spreading and screening device of the present invention shown, it includes a base 1 and a center ring 2. A plurality of spreading frames 3 with top openings are fixedly provided on the outer wall of the center ring 2 in a circumferential direction. A screen 4 is fixedly provided in the middle of each spreading frame 3. The screen 4 divides the spreading frame 3 into a spreading area 31 and an impurity area 32. A center column 21 is provided for rotation at the center of the center ring 2. A plurality of centrifugal components 5 for hitting the inner wall of the center ring 2 are circumferentially provided on the side wall of the center column 2. Specifically, the tea leaves can be evenly spread out through the plurality of spreading frames 3 to prevent the tea leaves from piling up and affecting the spreading effect. At the same time, when the center column 21 rotates, the centrifugal component 5 can continuously hit the inner wall of the center ring 2, thereby causing the screen 4 to vibrate, so that impurities such as broken residues in the tea leaves are hung into the impurity area 32, and the complete tea leaves are retained in the spreading area 31. The structure is simple and the design is ingenious.

[0017] In one embodiment of the present application, a debris discharge port 31 is provided below the side wall of the spreading frame 3 . Specifically, the debris discharge port 31 facilitates timely cleaning of impurities in the impurity area 32 .

One end of the tension spring 52 is fixedly connected to the inner wall of the fixed cylinder 51, and the other end of the tension spring 52 is fixedly connected to the impact rod 53. Specifically, when the center column 21 rotates, the center column 21 drives the fixed cylinder 51 to rotate synchronously. Under the action of centrifugation, the impact rod 53 continuously impacts the inner wall of the center ring 2, causing the multiple screens 4 to vibrate for screening.

[0020] In one embodiment of the present application, an impact ball 530 is fixedly provided at one end of the impact rod 53 away from the central column 21 .
